Answer:
y=-1/4x+1
Step-by-step explanation:
Hi there!
We're given the point (-8,3) and a slope of -1/4
lines are typically written in the formula y=mx+b, where m is the slope and b is the y intercept
as we are already given the slope, we can substitute its value into the equation
substitute -1/4 as m
y=-1/4x+b
now we need to find b
as the equation passes through the point (-8,3),we can use it to solve for b
substitute -8 as x and 3 as y
3=-1/4(-8)+b
multiply
3=2+b
subtract 2 from both sides
1=b
substitute 1 as b
y=-1/4x+1

in a school ,the number of boys who play cricket is 3 times as much as a number of boys who play tennis. if 12 boys, who play cricket, play tennis instead, the number of boys who play each of these sports would be the same. find the number of boys who play tennis
Answer:
The number of boys who play tennis is 36.
Step-by-step explanation:
Let the number of boys who play tennis is x.
number of boys who play cricket = y
x = 3 y..... (1)
12 boys plays both cricket and tennis.
According to the question,
x - 12 = y + 1 2
3 y - 12 = y + 12
2 y = 24
y = 12
So, the number of boys who plays tennis is x = 3 x 12 = 36.

The volume of prism for the given condition is 147 cm³.
What is volume of prism?A prism is a polyhedron comprising an n-sided polygon base, a second base which is a translated copy of the first, and n other faces, necessarily all parallelograms, joining corresponding sides of the two bases.
Here, Prism(Rectangle)
Length(L) = 3.5 cm.
Width(W) = 6 cm
Height (H) = 7 cm
Volume = Area of Rectangle x Height
Volume of Prism: V = L x W x H
V = 3.5 X 6 X 7
V = 147 cm³
Thus, The volume of prism for the given condition is 147 cm³.

Answer:
1 3/8
Step-by-step explanation:
We are to add 1/2 + 1/4 + 5/8
[tex]\frac{1}{2} + \frac{1}{4} + \frac{5}{8}[/tex]
[tex]\frac{4 + 2 + 5}{8}[/tex] = 11/8 = 1 3/8

Step-by-step explanation:
A lampshade has a height of 12cm and upper and lower diameters of 10cm and 20cm A)what area of material is required to cover that curved surface of the frustum B)what is the volume of the frustum (Give both answers in terms of pie)
Answer:
[tex](a)\ Area = 195\pi[/tex]
[tex](b)\ Volume = 700\pi[/tex]
Step-by-step explanation:
Given
[tex]h = 12[/tex]
[tex]d_1 = 10[/tex] --- lower diameter
[tex]d_2 = 20[/tex] --- upper diameter
Solving (a): The curved surface area
This is calculated as:
[tex]Area = \pi l(r_1 + r_2)[/tex]
Where
[tex]r_1 = 0.5 * d_1 = 0.5 * 10 = 5[/tex] --- lower radius
[tex]r_2 = 0.5 * d_2 = 0.5 * 20 = 10[/tex] --- upper radius
And
[tex]l = \sqrt{h^2 + (r_1 - r_2)^2[/tex] ---- l represents the slant height of the frustrum
[tex]l = \sqrt{12^2 + (5 - 10)^2[/tex]
[tex]l = \sqrt{12^2 + (-5)^2[/tex]
[tex]l = \sqrt{144 + 25[/tex]
[tex]l = \sqrt{169[/tex]
[tex]l = 13[/tex]
So, we have:
[tex]Area = \pi l(r_1 + r_2)[/tex]
[tex]Area = \pi * 13(5 + 10)[/tex]
[tex]Area = \pi * 13(15)[/tex]
[tex]Area = 195\pi[/tex]
Solving (b): The volume
This is calculated as:
[tex]Volume = \frac{1}{3}\pi * h * (r_1^2 + r_2^2 + (r_1 * r_2))[/tex]
This gives:
[tex]Volume = \frac{1}{3}\pi * 12 * (5^2 + 10^2 + (5 * 10))[/tex]
[tex]Volume = \frac{1}{3}\pi * 12 * (25 + 100 + (50))[/tex]
[tex]Volume = \frac{1}{3}\pi * 12 * (175)[/tex]
[tex]Volume = \pi *4 * 175[/tex]
[tex]Volume = 700\pi[/tex]

True or False: △XYZ has sides XY, YZ and XZ that measure 15 cm, 20 cm, and 25 cm respectively is a right triangle.
Please answer please
Answer:
True
Step-by-step explanation:
As a right triangle, it follows the Pathagorem Therom. All you have to do is multiply 15 x 15 = 225 and 20 x 20 = 400, then finally, you would do 25 x 25, which is the biggest number of all, and get 625. Since 225 + 400 = 625, this follows the Pathagorem Therom.

Isa finished 30% of his homework in 27 minutes. How many more minutes will it take Isa to complete his homework, assuming that he works at the same pace?
Answer:
90 Minutes
Step-by-step explanation:
If he took 27 minutes to do 30% of his homework, then we can reverse the operation to find the total amount
30% is the same as 0.3, therefore you divide 27 by 0.3 because the 100% is 1, so by dividing you'll get the 100%.
90 minutes
Step-by-step explanation:
So 27 = 30%
30% + 30% + 30% = 90%
27 + 27 + 27 = 81
30% ÷ 3 = 10%
27 ÷ 3 = 9
90% + 10% = 100%
81 + 9 = 90
