Answer:
[tex]\frac{7}{16}[/tex]
Step-by-step explanation:
=> [tex]\frac{13}{16}-\frac{3}{8}[/tex]
LCM = 16
=> [tex]\frac{13-6}{16}[/tex]
=> [tex]\frac{7}{16}[/tex]
Answer:
7/16
Step-by-step explanation:
13/16 - 3/8
Lowest common multiple is 16.
= 13/16 - 6/16
Subtract the fractions.
= (13-6)/16
= 7/16
Complete the square to rewrite y=x^2-6x+14 in vertex form. Then state whether the vertex is a maximum or minimum and give is coordinates. A. - Minimum at (3,5) B. - Minimum at (-3,5) C. - Maximum at (-3,5) D. - Maximum at (3,5)
Answer:
3,5, Minimum
Step-by-step explanation:
y=x²-6x+14
y=(x²-2*3x +3²-3²)+14
y=(x²-2*3x+3²)+14-9
y=(x-3)²+5
a=1
p=3
q=5
a>0 ⇒ vertex is minimum
V(p,q) ⇒ V(3;5)
Hazel buys a dress that costs $50.00. She pays 5% sales tax. How much does she pay for the dress with tax?
Answer:
$52.5
Step-by-step explanation:
Costing Price = $50
Tax = 5% of $50
=> [tex]\frac{5}{100} * 50[/tex]
=> 0.5*5
=> $2.5 Tax
Total Cost = CP + Tax
=> $50 + $2.5

Which of the following is an equivalent form of the compound inquality -44 > -2x-8 ≥-8
To solve a compound inequality, first separate it into two inequalities. Determine whether the answer should be a union of sets ("or") or an intersection of sets ("and"). Then, solve both inequalities and graph. To find the solution of the compound inequality, we look at the graphs of each inequality and then find the numbers that belong to both graphs—where the graphs overlap. For the compound inequality x>−3 and x≤2, we graph each inequality. if you use this formula you will be able to get the answer

Since they are congruent, triangle TUV just needs to be flipped around to find the length of UV.
Answer:
14 inches
Step-by-step explanation:
For these problems you just have to flip the image in your head to picture what the image will look like the other way around. If you flip it, you can see it's congruent to RS which measures 14 inches long. Therefore, it's 14 inches long.

A function is represented by the table. x y 3 -2 5 -26 7 -50 The rate of change of the function represented in the table is . For the given x- and y-values, the function is .
Answer:
Step-by-step explanation:
Here is your x/y table, a bit more organized:
x | 3 5 7
y | -2 -26 -50
The rate of change is the same thing as the slope. If the slope between coordinates 1 and 2 is the same as the slope between coordinates 2 and 3, we have a linear function in the form y = mx + b, where m is the slope and b is the y-intercept. We will have to solve for b if we want to use this form. Or we could use the point-slope form and not have to solve for b. Let's do that. But first things first. The slope:
Between the first 2 coordinates (3, -2) and (5, -26):
[tex]m=\frac{-26-(-2)}{5-3}=\frac{-24}{2}=-12[/tex]
Between coordinates 2 and 3 which are (5, -26) and (7, -50):
[tex]m=\frac{-50-(-26)}{7-5} =\frac{-24}{2}=-12[/tex]
The slopes are the same, so this in fact a linear function with m = -12. But that's all we have, so let's use the point-slope form of a line to write the equation:
[tex]y-y_1=m(x-x_1)[/tex] where [tex]x_1[/tex] and [tex]y_1[/tex] are coordinates found in the table. Plugging in the first coordinate along with the slope of -12:
[tex]y-(-2)=-12(x-3)[/tex] and
y + 2 = -12x + 36 and
y = -12x + 36 - 2 so the equation for the line in slope-intercept form is
y = -12x + 34
Regardless of which coordinate point you choose as your x1 and y1, I promise you that you will still get the same equation for the line!
Answer:
hi its -12 and decreasing.

If Connie deposits $100 into a savings account with a 3% annual interest rate and doesn't withdraw any of the money for 2 years, what will her balance be at the end of 2 years?
Answer:
The final amount/ her balance after two years is $106.09Step-by-step explanation:
We are going to assume that the balance compounds every year
applying the compound interest formula we have
[tex]A= P(1+r)^t[/tex]
where
A, final amount
P, Principal= $100
r, Rate= 3%= 0.03
T, time= 2years
substituting our values into the formula we have
[tex]A= 100(1+0.03)^2\\A=100(1.03)^2\\A=100*1.0609\\A=106.09\\[/tex]
The final amount/ her balance after two years is $106.09
The mean of the numbers 3, 6, 4, x and 7 is 5. Find the standard deviation.
Answer:
1.2
Step-by-step explanation:
Since (3 + 6 + 4 + x + 7)/5 = 5, then 3 + 6 + 4 + x + 7 equals 25. Adding, we have 20 + x = 25. Thus x = 5. Now we calculate how far each number is from the mean. 3 is 2 away. 6 is 1 away. 4 is also 1 away. 5 is 0 away, and 7 is 2 away. Now, we have to find the mean of this. (2 + 1 + 1 + 0 + 2 ) / 5 is equal to 6/5, which is 1.2
Find the number of sides of a polygon if each interior angle is 150°
Answer:
12
Step-by-step explanation:
The interior angle and exterior angle sum to 180° , thus
exterior angle = 180° - 150° = 30°
The sum of the exterior angles of a polygon = 360° , thus
number of sides = 360° ÷ 30° = 12

Answer: A) stretched vertically by 2 and shifted up 6 units
Step-by-step explanation:
y = A log(Bx - C) + D where
A = vertical stretch by a factor of AB = horizontal shrink by a factor of 1/BC = horizontal shift C units (positive = right, negative = left)D = vertical shift D units (positive = up, negative = down)Given: f(x) = log x
g(x) = 2 log x + 6
→ A = 2 vertical stretch by a factor of 2
→ D = +6 vertical shift UP 6 units
Which graph represents viable values for y = 2x, where x is the number of pounds of rice scooped and purchased from a bulk bin at the grocery store and y is the total cost of the rice? On a coordinate plane, a straight line with a positive slope begins at point (0, 0), and ends at point (2.5, 5). On a coordinate plane, blue diamonds appear at points (0, 0), (1, 2), (2, 4). On a coordinate plane, a straight line with a positive slope begins at point (negative 2.5, negative 5), crosses the x- and y-axis at point (0, 0), and ends at point (2.5, 5). On a coordinate plane, blue diamonds appear at points (negative 2, negative 4), (negative 1, negative 2), (0, 0), (1, 2), (2, 4).
Answer: Most Viable: On a coordinate plane, a straight line with a positive slope begins at point (0, 0), and ends at point (2.5, 5).
Also possible, but only if someone scoops exact amounts (maybe pre-packaged for people who don't want to do their own scooping.): On a coordinate plane, blue diamonds appear at points (0, 0), (1, 2), (2, 4).
Step-by-step explanation:
The line beginning at (0,0) ending at (2.5, 5) represents all the prices for any amount that the customer scoops. for example, $5 for 2 1/2 pounds or $1 for 1/2 pound or $2 for 1 pound would all be represented in the graphed line.
The graphs with negative values don't make sense. You can't scoop negative pounds!

Ash and Misty are both travelling by train. Ash's train travels 80 km in 50 minutes. Misty's train travels 160 km. It leaves at 12:35 and arrives at 15.05. Work out the difference, in km/h, between the average speed of their trains.
Answer:
∆v = 32 km/h
the difference, in km/h, between the average speed of their trains is 32 km/h.
Step-by-step explanation:
For Ash's Train;
Distance travelled d1 = 80km
Time taken t1 = 50 minutes = 5/6 hour
Average speed = distance travelled/time taken
v1 = d1/t1
Substituting the values;
v1 = 80/(5/6)
v1 = 96km/h
For Misty's train;
Total distance travelled d2 = 160 km
Time taken t2 = 15:05 - 12:35 = 2 hours 30 minutes
t2 = 2.5 hours
v2 = d2/t2 = 160/2.5
v2 = 64 km/h
the difference, in km/h, between the average speed of their trains is;
∆v = v1 - v2 = 96km/h - 64 km/h = 32 km/h
∆v = 32 km/h
the difference, in km/h, between the average speed of their trains is 32 km/h.
Answer:
32km/h

Pls Anyone help me!!
Answer:
Put the values into the formula....let me know if you need help....
Step-by-step explanation:
Answer: 0
Step-by-step explanation:
Sum of the first 9 terms = 9/2 (2a + 8d)
Sum of the first 11 terms = 11/2 (2a + 10d)
S9 = S11
9a + 36d = 11a + 55d
2a = -19d
2a + 19d = 0...........(1)
S20 = 20/2 (2a + 19d)
= 20/2 (0) . .. ............from (1)
S20 = 0

A recipe for oatmeal cookies calls for 5 cups of flour for every 6 cups of oatmeal. How much flour is needed for a big batch of cookies that uses 18 cups of oatmeal?
Answer:
15
Step-by-step explanation:
So first you need to find out how many groups of 6 cups of oatmeal there are. So for this just do 18/6=3
So now you should be able to find the amount of flour by doing 5*3=15
The flour is needed for a big batch of cookies that uses 18 cups of oatmeal would be 15 cups.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
In order to find out how many groups of 6 cups of oatmeal there are.
So, For every 6 cups of oatmeal = 18/6=3
Now,
For 5 cups of flour = 5 x 3 = 15
The flour is needed for a big batch of cookies that uses 18 cups of oatmeal would be 15 cups.
