12+4y=-4x slope intercept equation
Answer: y=-x-3
Step-by-step explanation:
What is the equation of a line that has a slope of 0 and goes through the point (4, 10)?
Answer:
y =10
Step-by-step explanation:
The equation of a line in point slope form is expressed as;
y - y0 = m(x-x0)
m is the slope
(x0, y0) is the point on the line
Given
m = 0 and (x0, y0) = (4, 10)
On substituting;
y - 10 = 0(x-4)
y - 10 = 0
y = 0+10
y = 10
Hence the required equation of the line is y =10
350 students signed up what percent signed up for the airforce (64)
Answer: 18.29%
Step-by-step explanation:
There are 350 students. Out of these students, 70 signed up for the Army, 64 for the Airforce, 56 for the Navy and 160 for the Marines for a total of 350.
The percentage of students who signed up for the Airforce out of the total can be calculated by:
= number of students (airforce) / total number of students * 100
= 64/350 * 100
= 18.29%
A scale of 1:20 is used to make the drawing of a car if the length of the drawing is 10 what is the real length of the car?
Answer: 200
Step-by-step explanation:
since 10 is one part
10 x 20 = 200
The real length of the car will be 200 units.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
A scale of 1:20 is used to make the drawing of a car.
And, The length of the drawing is 10.
Now,
Since, The length of the drawing is 10.
And, The used scale = 1 : 20
Hence, The real length of the car = 20 × 10
= 200 units

Answer:kilometers
Step-by-step explanation:
a rectangles side lengths are 8 cm and 4 cm. Approximate the length of the diagonal of the rectangle to the nearest tenth.
Answer:
8.4cm
Step-by-step explanation:
first you have to square both sides
8²+4²= Hypotenuse (the diagonal)
you'll get
56 + 16
next you add it, and it'll equal 72
lastly you'll find the square root of that number
which is going to give you 8.4
What is the slope of a line parallel to the line whose equation is x-3y=-27 Fully reduce your answer
Answer:
1/3Step-by-step explanation:
Note that any line parallel to the given line will have the same slope as the line given.
Given the equation of the line expressed as x - 3y =-27
Rewrite in standard form y = mx+c where m is the slope
x - 3y =-27
-3y = -x -27
Multiply through by -11
3y = x+27
Divide through by 3
y = 1/3 x + 9
Since the slope of the line is 1/3, hence the slope of a line parallel to the line is also 1/3
Carl sees 25 melons at the store. 15 are small and the rest are large. How many melons are large?
Answer: 10 large melons
Step-by-step explanation:
Carl saw 25 melons at a store.
Of these 25, 15 were small and the rest were large.
The number of large melons will have to be the whole total of 25 melons less the number of small melons which is 15:
= 25 total melons - 15 small melons
= 10 large melons

A model of Steven’s house is shown in the diagram. He is replacing the roof, which consists of two rectangular surfaces. The diagram shows one side of the roof, with the other side hidden from view. What is the total area of the roof to the nearest square foot?
Answer:
Option B
Step-by-step explanation:
From the picture attached,
Area of the one side of the roof = Area of the rectangle
= Length × Width
= AE × AC
To get the length of side AC, construct a perpendicular AD on side BC which divides BC in two equal parts.
BD = DC = 13 ft
By applying cosine rule in ΔADC,
cos(45)° = [tex]\frac{\text{DC}}{\text{AC}}[/tex]
[tex]\frac{1}{\sqrt{2}}=\frac{13}{\text{AC}}[/tex]
AC = 13√2
AC = 18.38 ft
Therefore, area of one side of the roof = 38 × 18.38
= 698.62 square feet
Area of both the sides of the roof = 698.62 × 2
= 1397.24 feet²
≈ 1397 feet²
Option B will be the answer.
The total area of the roof to the nearest square foot is 1,397 square feet
Area of composite shapes.In order to get the area of the roof, we will need the slant height of the triangle.
Using the pythagoras theorem;
[tex]cos45 = \frac{26/2}{l} \\cos 45 = \frac{13}{l} \\0.7071 = \frac{13}{l} \\l = \frac{13}{0.7071} \\l=18.39 feet[/tex]
Get the area of the roofArea of the roof = 2(lw)
l is the length of the rectangle = 38ftw is the width = 18.39 feetArea of the roof = 2(38 * 18.39)
Area of the roof = 1,397.64
Area of the roof ≈ 1,397 square feet
Hence the total area of the roof to the nearest square foot is 1,397 square feet

Answer:

Step-by-step explanation:
There is a common difference d in the values, that is
9 - 5 = 13 - 9 = 17 - 13 = 21- 17 = 4
To obtain a term in the sequence add 4 to the previous term, thus
t₉ = t₈ + 4 → C
(b)
Given the n th term formula 3n - 8
To find any term, substitute the term position n into the formula
(i) first term (n = 1), then
3(1) - 8 = 3 - 8 = - 5
(ii) tenth term (n = 10, then
3(10) - 8 = 30 - 8 = 22
(iii) 100 th term ( n = 100), then
3(100) - 8 = 300 - 8 = 292
A bucket is leaking.After 3hr the bucket has leaked 3/4 of an ounce.How many ounces per hour is the bucket leaking 3/4oz-3hr= 3/4 divided by 5/1= _x_=oz /1hr
Answer: 1/4 ounces per hour
Step-by-step explanation:
In the 3 hours that the bucket has leaked, it has lost 3/4 ounces.
The rate at which it is leaking is therefore:
= 3/4 / 3
= 3/4 * 1/3
= 3/12
= 1/4 ounces per hour

The ratio of Rogers age to his sons is 7:3. If the sum of their ages are 60 how old is Rogers son
Answer:24
Step-by-step explanation:
Sum of their ages is 60 yr. As such
7x + 3x = 60
10x = 60
x = 60 / 10
x = 6
The rationale is 6, therefore
Father's age is 7x = 7 × 6= 42 years
Son's age is 3x = 3 × 6 = 18 years
Difference in their ages
42 - 18 = 24 years

Find the solution of the system of equations 3x+3y=6
9x-5y=-24
Answer:
Then the answer to the system is the point (-1, 3)
which corresponds to x = -1 and y = 3
Step-by-step explanation:
Start by dividing the first equation by 3 on both sides, and get:
x + y = 2
now multiply it by 5 in order to be able to eliminate the term in y in the combining of both equations:
5 x + 5 y = 10
+
9 x - 5 y = - 24
___________
14 x + 0 = -14
solve for x by dividing both sides by 14:
x = -14/14 = -1
Use the x = -1 answer in the equation 3 x + 3 y = 6 and solve for y:
-3 + 3 y = 6
add 3 on both sides:
3 y = 9
divide both sides by 3 to isolate y:
y = 3
Then the answer to the system is the point on the plane (-1, 3)
which corresponds to x = -1 and y = 3
A container holds 600 kg of rice . 33 1/3% of rice was distributed to groceries . How many kilograms of rice remained in the container
Answer:
Amount left in the container is [tex]400\:\text{kg}[/tex].
Step-by-step explanation:
Given: A container holds [tex]600[/tex] kg of rice. [tex]33 \frac{1}{3} \%[/tex] of rice was distributed to groceries.
To find: How many kilograms of rice remained in the container?
Solution:
We have,
Amount of rice in the container [tex]=600[/tex] kg
Amount distributed to the groceries [tex]=33 \frac{1}{3} \%= \frac{100}{3}\%[/tex]
Therefore, amount distributed to groceries[tex]=\frac{100}{3}\times\frac{1}{100}\times600=200 \:\text{kg}[/tex]
Now, amount of rice left in the container[tex]=600\:\text{kg}-200\:\text{kg}=400\:\text{kg}[/tex]
Hence, amount of rice left in the container is [tex]400 \:\text{kg}[/tex].
[tex]\bold{\underline{Answer : -}}[/tex]
Amount of the rice left in container = 400kg[tex] \: [/tex]
[tex]\bold{\underline{Explanation : -}}[/tex]
(33⅓)% = (100/3)%[tex] \longmapsto \sf( \frac{100}{3} )\% \times 600 [/tex]
[tex] \longmapsto \sf( \frac{ \frac{100}{3} }{100} ) \times 600 \\ \longmapsto \sf\frac{ \cancel{100}}{3} \times \frac{1}{ \cancel{100}} \times 600 \\ \longmapsto \sf \frac{1}{3} \times 600 = \frac{600}{3} = 600 \div3 \\ \longmapsto \bold \red{200kg}[/tex]
Soo :
[tex] \longmapsto \sf600kg \times 200kg \\ \longmapsto \boxed{ \bold{ \underline{400kg}}}[/tex]
