What value correctly fills in the blank so that the expressions are equivalent?
32 + 72 = blank x (4 + 9)
Answer:
8
Step-by-step explanation:
8*4 is 32 8*9 is 72
so, it is 8
since it is distributive property 8(4+9)
Answer:
8
Step-by-step explanation:
1) simplify the equation
32+72=104
104=4x+9x (distibute the "x")
104=13x
x=8
hence the "blank" is 8

The polygons are similar. The area of one polygon is given. Find the area of the other polygon.
4 cm
12 cm
A = 10 cm
Area =
cm2
Answer:
90 cm²
Step-by-step explanation:
Given that both triangles are similar, it follows that the ratio of their area equals the square of their corresponding sides.
Let the area of the other triangle be x. Therefore:
[tex] \frac{10}{x} = \frac{4^2}{12^2} [/tex]
[tex] \frac{10}{x} = \frac{16}{144} [/tex]
Cross multiply
[tex] 10*144 = 16*x [/tex]
[tex] 1440 = 16x [/tex]
Divide both sides by 16
90 = x
Area of the other polygon = 90 cm²
Answer:
Answer is 90

you use 4 gallons of water on 30 plants in your garden. At the rate,how much water will it take to water 45 plants
Answer:4 gallons of water ... 30 plants
x gallons of water = ? ... 45 plants
If you would like to know how much water will it take to water 45 plants, you can calculate this using the following steps:
4 * 45 = x * 30
180 = 30 * x /30
x = 180 / 30
x = 6 gallons of water
Result: You will use 6 gallons of water to water 45 plants.

Answer:

Step-by-step explanation:
Answer:
y = 4[tex](2)^{x}[/tex]
Step-by-step explanation:
An exponential function in standard form is
y = a[tex]b^{x}[/tex]
Substitute points from the graph into the equation to find a and b
Using (0, 4 ), then
4 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ], so
a = 4
y = 4[tex]b^{x}[/tex]
Using (1, 8 ), then
8 = 4[tex]b^{1}[/tex] = 4b ( divide both sides by 4 )
b = 2
y = 4 [tex](2)^{x}[/tex] ← exponential equation

Find the midpoint of the segment.
A. (4, 2)
B. (1, 0)
C. (-4, 0)
D. (0, 1)
Answer:
B. (1, 0)
Step-by-step explanation:
9514 1404 393
Answer:
B. (1, 0)
Step-by-step explanation:
You can count grid squares on the graph to find the point that is 4 of the 8 units horizontally between the points, and 2 of the 4 units vertically between the points. That will be ...
C +(4, 2) = D -(4, 2) = (1, 0)
__
Or, you can use the midpoint formula:
M = (C +D)/2
M = ((-3, -2) +(5, 2))/2 = (-3+5, -2+2)/2 = (2, 0)/2
M = (1, 0)
The midpoint is (1, 0).

What is a parallelogram?A parallelogram is a quadrilateral that has two pairs of parallel sides.
In a parallelogram, opposite sides and angles are equal.
The adjacent angles add up to 180 degrees.
We have,
Three vertices of the parallelogram ABCD.
A = (0, 2)
B = (8, 1)
D = (3, 4)
C = (x, y)
A___________B
/ /
/ O /

D C
Now,
AO = OC
BO = DO
O is the midpoint of BD.
O =(m, n)
m = (8 + 3) / 2
m = 11/2
n = (1 + 4)/2
n = 5/2
O = (11/2, 5/2)
Now,
O is the midpoint of AC.
m = (x + 0)/2
11/2 = x/2
x = 11
n = (y + 2)/2
5/2 = (y + 2)/2
y + 2 = 5
y = 3
The coordinates of C.
= (x, y)
= (11, 3)
Thus,
The coordinates of vertex C are (11, 3).

a rectangle has a length 3 meters more than three times the width. the area of the rectangle is less than 90 meters squared. write an expression that represents all possible widths (use the variable x) of the rectangle. write your answer as an inequality, a < x < b.
Answer: -6<x<5
Step-by-step explanation:
Given
Length is 3 m more than three times the width
Suppose width is x
So, the length is 3x+3
The area of a rectangle is [tex]length\times width[/tex]
Area= [tex](3x+3)x<90[/tex]
[tex]\Rightarrow 3x^2+3x-90<0\\\Rightarrow x^2+x-30<0\\\Rightarrow x^2+6x-5x-30<0\\\Rightarrow (x+6)(x-5)<0\\\Rightarrow -6<x<5[/tex]
Daniel rollerbladed 3 miles in 12 minutes. At this rate, how many miles will he rollerblade in 1 hour? Show your work.
Answer:
Daniel is rollerblading at 15 miles per hour
Daniel can go 3 miles in 12 minutes so we do 12÷3 to find out how many minutes it takes to go 1 mile which is 4 now we do 60÷4 to get 15
Alternatively we could do 60÷12 to get 5 then do 3×5 to get 15

Which of the following best describes the graph above?
A.
neither a relation nor a function
B.
function only
C.
relation only
D.
both a relation and a function
Answer:
Option C
Step-by-step explanation:
To test a graph whether it represents a function or relation we conduct a vertical line graph.
If the vertical line intersect the graph at two different points, graph represents a relation only.
By analyzing the given graph with the vertical line test,
Since, a vertical line (x = -4) intersect the graph at two points (y = -1 and y = 5),
Given graph represents a relation only.
Option C is the answer.

You lose 2 points every time you forget to write your name on a test. You have forgotten to write your name 4 times. What integer represents your change in points from forgetting to write your name?
Answer:
-8
Step-by-step explanation: since it says Times, (for me times is multiplication) you would multiply -2 and 4. negative 2 would be from that person losing 2 points. and 4 since it is your total amount of times you have forgotten to write your name. so, -2 x 4 = -8.
how i got -8. both signs from -2 and 4 are different, and when they are different the answer will always be negative.

Riya wants curtains in her room. These are the lengths of curtains in metres. 1.0 m, 1.25 m, 1.5 m The lengths follow a pattern. Riya wants the next length up from 1.5 m. What length of curtains will Riya buy?
Answer:
1.75
Step-by-step explanation:
Since the curtains are going up in .25. We need to add .25 to 1.5.
1.5 + .25 = 1.75
The length of curtains will Riya buy is 1.75 m.
What is sequence?A sequence is an arrangement of numbers in a specific order. A series, on the other hand, is defined as the sum of the elements in a sequence.
For example, In the sequence 1, 3, 5, 7, 9, …, 1 is the first term, 3 is the second term, 5 is the third term, and so on.
We have length of curtains as
1m, 1.25 m, 1.5 m,...
Now, from above the first term is 1.
Common difference, d= 1.25 - 1 = 0.25
So, the next length of curtain will be
= 1 + (4-1)0.25
= 1 + 0.75
= 1.75 m
