To steam rice, Paul uses m cups of water for every p
cups of rice. In terms of m and p, how many cups of
water are needed to steam p + 2 cups of rice?
Answer:
[tex]\frac{(p + 2)m}{p}[/tex]
Step-by-step explanation:
Given
m cups of water = p cups of rice
Required
Cups of water required for p + 2 cups of rice
The question shows a direct proportion between cups of rice and cups of water.
So, the first step is to get the proportionality constant (k)
This is calculated using the following expression;
[tex]m = k * p[/tex]
Where k represents cups of water and p represents cups of rice
Make k the subject of formula
[tex]k = \frac{m}{p}[/tex]
Let x represents cups of water when cups of rice becomes p + 2;
k becomes:
[tex]k = \frac{x}{p + 2}[/tex]
Equate both expressions of k; to give
[tex]\frac{m}{p} = \frac{x}{p + 2}[/tex]
Multiply both sides by p + 2
[tex](p + 2) * \frac{m}{p} =(p + 2) * \frac{x}{p + 2}[/tex]
[tex](p + 2) * \frac{m}{p} =x[/tex]
[tex]x = (p + 2) * \frac{m}{p}[/tex]
[tex]x = \frac{(p + 2)m}{p}[/tex]
Hence, the expression that represents the cups of water needed is [tex]\frac{(p + 2)m}{p}[/tex]
A car accelerates uniformly from 36 km/h to 72 km/h in 2 seconds. Calculate :a.The acceleration of the car b.The distance covered by the car in that time.
Answer:
(a) The acceleration of the car is 5 m/s²
(b) The distance covered by the car in that time is 30 m
Step-by-step explanation:
Given;
initial velocity of the car, u = 36 km/h = 10 m/s
final velocity of the car, v = 72 km/h = 20 m/s
time for the motion, t = 2 seconds
(a) .The acceleration of the car;
v = u + at
[tex]a = \frac{v-u}{t} \\\\a = \frac{20-10}{2}\\\\a = 5 \ m/s^2[/tex]
(b) The distance covered by the car in that time
[tex]s = (\frac{v+u}{2} )t\\\\s = (\frac{20+10}{2} )*2\\\\s = 30 \ m[/tex]
Problem: \ The yellow portion of a circle represents 35%: How many degrees are in the angle formed by the edges of the yellow region?
Answer:
126°
Step-by-step explanation:
Given that the yellow portion covers 35% of the circle, the degree formed by its edges can be calculated as follows:
The degree of a full circle = 360°
To find the degree formed by the edges of the yellow region, we would calculate 35% of 360°:
[tex] \frac{35}{100}*360 [/tex]
[tex] \frac{35*360}{100} [/tex]
[tex] \frac{12600}{100} [/tex]
[tex] \frac{126}{1} [/tex]
[tex] 126 [/tex]
126° is formed by the edges of the yellow region.

******BRAINLIEST IF ANSWERED****** Which equation can be used to find the measure of angle BAC? * inverse tan(5/12) inverse cos(5/13) inverse sin(12/5) inverse tan(12/13)
Answer:
[tex]cos^{-1}(\frac{5}{13} )[/tex]
Step-by-step explanation:
We can see that x is at ∠A.
To find x:
cosx° = 5/13
x = cos^-1(5/13)
sinx° = 12/13
x = sin^-1(12/13)
tanx° = 12/5
x = tan^-1(12/5)
Out of our answer choices, the only one that fits is the inverse cos(5/13).

Which of the following is the sum of the slopes of the line 3x+y=1 and a line perpendicular to this line? A 0 B 13 C −83 D −6
Answer:
-8/3
Step-by-step explanation:
First find the slope of the line
3x+y = 1
Solve for y
y = -3x+1
This is in slope intercept form
y = mx+b where m is the slope
The slope is -3
The slopes of perpendicular lines multiply to -1
m* -3 = -1
m = 1/3
The line perpendicular has a slope of 1 / (3) = 1/3
The sum is -3 + 1/3
-9/2 + 1/3 = -8/3

rene is 6 years older than her younger sister after 10 years the sum of their ages will be 50 find their persent ages
Answer:
Rene = 18
Sister = 12
Step-by-step explanation:
Let
Rene's age be 6+x
Her sister's age be x
Given that:
6+x+10+x+10 = 50
To calculate their ages, we have to find out the value of x. To find the value of x, rearrange and solve the above equation:
6+x+10+x+10 = 50
26 + 2x = 50
2x = 50-26 = 24
x = 12
We said at the start that Rene's age was 6+x, so her age = 12+6 = 18
Rene's sister's age = x = 12
Hope this helps
Answer:
18 , 12
Step-by-step explanation:
R -Rene age
R-6= age of her sister
after 10 years Rene age=R+10
her sister age= R-6+10=R+4
so R+10+R+4=50
2R+14=50
-14 -14
2R=36
:2 :2
R=18 ( Rene age)
18-6=12 ( her sister age)

Answer:
6. E
7. D
8. 5,-8,34
Step-by-step explanation:
A. Parallel to the y-axis and passes through the point (3,5)
For it to be parallel to the y-axis, what this means is that it has an x-intercept and no y intercept.
So what this means is that x = 3 is our line so E is correct
B. Perpendicular to the y-axis means it is parallel to the x-axis
It means is has no x intercept and thus its x value at any point in time is zero
So the equation is y = -5
or simply y + 5 = 0 which means D is correct
C. It is parallel to the line 5x -8y + 12 = 0
Thus: 8y = 5x + 12
dividing both sides by 8
y = 5x/8 + 12/8
y = 5x/8 + 3/2
y = 5x/8 + 1.5
Comparing this with the general equation of a straight line ;
y = mx + c
where m is that slope, this means that 5/8 is the slope of the line
Mathematically if two lines are parallel, they have equal slopes.
So we can say the slope of the other line too is 5/8
Now to find the equation of the other line, we can use the point-slope method
y-y1 = m(x-x1)
where (x1,y1) in this case is (-2,3)
So we have;
y-3 = m(x-(-2))
y-3 = 5/8 (x + 2)
8(y-3) = 5(x + 2)
8y -24 = 5x + 10
5x + 10 + 24 -8y = 0
5x -8y + 34 = 0
So A, B, C = 5, -8, 34
Find the slope of the line that passes through:
(-2,-5) and (8, -11)
Answer:
Slope= [tex]\frac{-3}{5}[/tex]
Step-by-step explanation:
(-2 , -5) ; (8,-11)
[tex]Slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{-11-[-5]}{8-[-2]}\\\\=\frac{-11+5}{8+2}\\\\=\frac{-6}{10}\\\\=\frac{-3}{5}[/tex]

A circle with radius of \greenD{2\,\text{cm}}2cmstart color #1fab54, 2, start text, c, m, end text, end color #1fab54 sits inside a \blueD{7\,\text{cm} \times 11\,\text{cm}}7cm×11cmstart color #11accd, 7, start text, c, m, end text, times, 11, start text, c, m, end text, end color #11accd rectangle. What is the area of the shaded region? Round your final answer to the nearest hundredth.
Answer:
64.43 cm^264.44 cm^2 using π = 3.14Step-by-step explanation:
The area of the 7 cm by 11 cm rectangle is ...
A = bh
A = (7 cm)(11 cm) = 77 cm^2
The area of the circle of radius 2 cm is ...
A = πr^2 = π(2 cm)^2 = 4π cm^2
If the shaded area lies between the circle and the rectangle, its area is the difference of these:
shaded area = 77 cm^2 -4π cm^2
Using π = 3.14, this area is ...
(77 -4·3.14) cm^2 = 64.44 cm^2
Using π = 3.141592, this area is ...
(77 -4·3.141592) cm^2 ≈ 64.43 cm^2
The shaded area is 64.43 cm^2, (64.44 if you use π=3.14).

Comment on π
Often, you are required to use a specific valued for π, even if that is inappropriate for the number of significant digits required in the answer. In recognition of that, we have offered both the correct answer (64.43) and the one associated with the value of π you may be expected to use.
Answer:
64.43cm ^2
Step-by-step explanation:
First, calculate the area of the whole figure, including the unshaded area.
The area of a rectangle is the length times the width.
7cm x 11cm = 77c[tex]m^{2}[/tex]
Next, calculate the area of the inner figure.
The area of a circle is [tex]\pi[/tex][tex]r^{2}[/tex]
[tex]\pi[/tex] x 2cm x 2cm = 4[tex]\pi[/tex] c[tex]m^{2}[/tex]
Finally, subtract the area of the inner circle from the area of the outer rectangle.
77 c[tex]m^{2}[/tex] - 4[tex]\pi[/tex] c[tex]m^{2}[/tex] ≈ 64.43 c[tex]m^{2}[/tex]

The distance, y, in centimeters, of an ant from a hole in the tree for a certain amount of time, x, in seconds, is shown in the graph, photo above
Part A: Is the graph linear or nonlinear? Explain your answer. (2 points)
Part B: In which segments is the graph increasing, decreasing, and constant? (3 points)
Part C: In your own words, describe the motion of the ant, as shown on the graph (6 points)
Answer:
a. The graph is non-linear. If the graph was linear, it would be one continuous straight line.
b. The graph is increasing from x = 0 to x = 2, constant at x = 2 to x = 3, and decreasing from x = 3 to x = 5. So, [0, 2) is increasing, [2, 3) is constant, and [3, 5] is decreasing.
c. The ant starts to travel 6 cm away from the nest for 2 seconds. Between 2 to 3 seconds, it stays the same distance away. Then, after 3 seconds, it comes back to the base. At 5 seconds, it has returned.
Step-by-step explanation:
Answer:
Part A: it is linear because it is not curving and it consists of straight lines.
Part B: in side A it is increasing because it has a positive slope. In side b it is constant because the slope is 0 since it is straight. Finally, side C is decreasing because the slope is negative.
Part C: during side A the ant is crawling out of the hole in 2 seconds. After that, the ant stops for 2 more seconds as shown in side B. Then, he crawls back into the hole as shown by the decrease in distance due to the slope.

Nadine sold two kinds of tickets to her class play. Student tickets cost $3 each, and adult tickets cost $5.50 each. If Nadine sold a total of 25 tickets for $90, how many student tickets did she sell?
Answer:
19 tickets
Step-by-step explanation:
Nadine sold two kinds of tickets to her class play
The student tickets cost $3
Adult tickets cost $5.50
Nadine sold a total of 25 tickets for $90
We are required to find the number of students tickets that were sold
Let x represent the number of tickets sold to students
Let y represent the number of tickets sold to adults
x + y= 25
x= 25-y..........equation 1
Since the total cost of the ticket is $90
3x + 5.50y=90..........equation 2
Substitute 25-y for x in equation 2
3(25-y) + 5.50y= 90
75-3y+5.50y= 90
75+2.5y= 90
Collect the like terms
2.5y= 90-75
2.5y=15
Divide both sides by 2.5
2.5y/2.5=15/2.5
y= 6
Substitute 6 for y in equation 1
x= 25-y
x= 25-6
x= 19
Hence Nadine sold 19 student tickets

AB and AC are tangent. Find AB
Answer:
[tex]AB = \frac{11}{2}[/tex]
Step-by-step explanation:
Given
The above diagram
[tex]AB = 3y + 4[/tex]
[tex]AC = 11y[/tex]
Required
Determine length AB
Tangents drawn from the same point of a circle are equal;
This implies that
[tex]AB = AC[/tex]
Substitute values for AB and AC
[tex]3y + 4 =11y[/tex]
Subtract 3y from both sides
[tex]3y - 3y + 4 = 11y - 3y[/tex]
[tex]4 = 8y[/tex]
Divide both sides by 8
[tex]\frac{4}{8} = \frac{8y}{8}[/tex]
[tex]\frac{4}{8} = y[/tex]
[tex]\frac{1}{2} = y[/tex]
Substitute [tex]\frac{1}{2}[/tex] for y in [tex]AB = 3y + 4[/tex]
[tex]AB = 3 * \frac{1}{2} + 4[/tex]
[tex]AB = \frac{3}{2} + 4[/tex]
[tex]AB = \frac{3 + 8}{2}[/tex]
[tex]AB = \frac{11}{2}[/tex]

Step-by-step explanation:
Which cannot be the angle measurements of triangle ABC? Measure of angle A = 55 degrees, measure of angle B = 65 degrees, measure of angle C = 60 degrees Measure of angle A = 60 degrees, measure of angle B = 60 degrees, measure of angle C = 60 degrees Measure of angle A = 57 degrees, measure of angle B = 58 degrees, measure of angle C = 65 degrees Measure of angle A = 61 degrees, measure of angle B = 57 degrees, measure of angle C = 61 degrees
The last set should not be the angle of the measurements of triangle ABC i.e. Measure of angle A = 61 degrees, measure of angle B = 57 degrees, measure of angle C = 61 degrees
Calculation of the angle measurements:If we add the three sides of triangle so its total should be 180 degrees
So
= 55 + 65 + 60
= 180
Now
= 60 + 60 + 60
= 180
Now
= 57 + 58 + 65
= 180
And,
= 61 + 57 + 61
= 181
Therefore, The last set should not be the angle of the measurements of triangle ABC i.e. Measure of angle A = 61 degrees, measure of angle B = 57 degrees, measure of angle C = 61 degrees
