O The quadrilaterals have corresponding angles that are congruent.
0 The quadrilaterals are all the same size and shape.
O The quadrilaterals are different shapes but the same size.
O The quadrilaterals have corresponding sides that are congruent.
Answer:
B. The quadrilaterals are all the same size and shape.
Step-by-step explanation:
Lauren was drawing a tower ONLY using SIMILAR quadrilaterals, so since that is, since the quadrilaterals are similar, then they must have the same size and shape.
The statement i.e. true for quadrilaterals should be
B. The quadrilaterals are all the same size and shape.
What are quadrilaterals?A quadrilateral refer to the closed shape also it is the type of polygon that comprises of four sides, four vertices, and the four angles. Here the sum of the interior angle should be equivalent to the 360 degrees.

what you find 420% of 85 what are you looking for?
Answer:
420% of 85 = 357
Step-by-step explanation:
85/x=100/420
(85/x)*x=(100/420)*x - we multiply both sides of the equation by x
85=0.23809523809524*x - we divide both sides of the equation by (0.23809523809524) to get x
85/0.23809523809524=x
357=x
x=357

Sales tax on a shirt is 0.07 times the cost of the shirt. The sales tax for a shirt is $1.26. Which equation could you use to find the cost, c, of the shirt before sales tax? A. 0.07 · c = 1.26 B. 0.07 · 1.26 = c C. 0.07 ÷ 1.26 = c D. 0.07 ÷ c = 1.26
Answer:
Option A: 0.07c = 1.26 is the correct answer
Step-by-step explanation:
Given that the price of shirt is denoted by c.
Given that the sales tax is 0.07 times of the cost of shirt.
Mathematically it can be written as:
[tex]Sales\ tax=0.07c[/tex]
Now it is also given in the statement that the sales tax is $1.26
Putting this value in the above equation
[tex]1.26 = 0.07c[/tex]
As we have to find the cost, dividing both sides by 0.07
[tex]\frac{1.26}{0.07} = \frac{0.07x}{0.07}\\c = \frac{1.26}{0.07}[/tex]
Hence, we saw that the intermediate equation was: 1.26 = 0.07c
So,
Option A: 0.07c = 1.26 is the correct answer
Answer: A. 0.07 · c = 1.26
Step-by-step explanation:
Sales tax (0.07) x cost (c) = price (1.26)
When Jake volunteers at the animal shelter, he divides Two-thirds cup of cat food equally between 2 cats. How much food does he give each cat? Use the area model. Two-thirds divided by 2= ?????
Answer: 1/3
Step-by-step explanation:
From the question, we are informed that when Jake volunteers at the animal shelter, he divides two-thirds cup of cat food equally between 2 cats.
The amount of food that is given to each cat will be:
= 2/3 ÷ 2
= 2/3 × 1/2
= 1/3
Each cat gets 1/3 of the food

Answer:
The average rate of change of the function [tex]g(x)=x^2+10x+18[/tex] over the interval [tex]-11 \leq x\leq -1[/tex] is -1
Step-by-step explanation:
We are given the function [tex]g(x)=x^2+10x+18[/tex] over the interval [tex]-11 \leq x\leq -1[/tex]
We need to find average rate of change.
The formula used to find average rate of change is : [tex]Average \ rate \ of \ change=\frac{g(b)-g(a)}{b-a}[/tex]
We have b=-1 and a=-11
Finding g(b) = g(-1)
[tex]g(x)=x^2+10x+18\\Putting \ x=-1\\g(-1)=(-1)^2+10(-1)+18\\g(-1)=1-10+18\\g(-1)=9[/tex]
Finding g(a) = g(-11)
[tex]g(x)=x^2+10x+18\\Putting \ x=-11\\g(-11)=(-11)^2+10(-11)+18\\g(-1)=121-110+18\\g(-1)=29[/tex]
Finding average rate of change
[tex]Average \ rate \ of \ change=\frac{g(b)-g(a)}{b-a}\\Average \ rate \ of \ change=\frac{9-29}{-1-(-11)}\\Average \ rate \ of \ change=\frac{-10}{-1+11}\\Average \ rate \ of \ change=\frac{-10}{10}\\Average \ rate \ of \ change=-1[/tex]
So, the average rate of change of the function [tex]g(x)=x^2+10x+18[/tex] over the interval [tex]-11 \leq x\leq -1[/tex] is -1

Pllllzzzzz hellllpppp!!! What is an equation of the line that passes through the point (2,2) and is parallel to the line x-2y=4
Answer:
-2y = 4 - x
2y = x - 4
y = 1/2x - 2
1/2 is the slope of both lines.
y = mx + b
Substitute the given point and the common slope
2 = 1/2 x 2 + b
2 = 1 + b
b = 1
y = 1/2x + 1
The equation of the line that passes through the point
(2, 2) and is parallel to the line x - 2y = 4 is y = 1/2x + 1 or 2y = x + 2.
hope this helps u
plz give me the brainliest i really need it
Answer:
x - 2y = - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
x - 2y = 4 ( subtract x from both sides )
- 2y = - x + 4 ( divide all terms by - 2 )
y = [tex]\frac{1}{2}[/tex] x - 2 ← in slope- intercept form
with slope m = [tex]\frac{1}{2}[/tex]
Parallel lines have equal slopes, thus
y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute (2, 2) into the partial equation
2 = 1 + c ⇒ c = 2 - 1 = 1
y = [tex]\frac{1}{2}[/tex] x + 1 ← equation in slope- intercept form
Multiply through by 2
2y = x + 2 ( subtract 2y from both sides )
0 = x - 2y + 2 ( subtract 2 from both sides )
- 2 = x - 2y, that is
x - 2y = - 2 ← equation in standard form
Is there an ordered pair?
Answer: Yes, there is an ordered pair solution
The quick way we can see this without having to graph or do any algebra is to look at the two slopes of the lines.
y = x+1 has slope of 1
y = -x+5 has slope of -1
Recall that y = mx+b has slope m.
The two different slopes (1 and -1) indicate the lines are not parallel, so they must intersect exactly once. This intersection is the where the solution is located.

In a scale drawing of a house, 2 inches : 5 feet. The actual kitchen of the house will be 17 feet long. How long will the drawing of the kitchen be? ( Hint: Not A)
A. 5.2
B. 6.8
C. 7.5
D. 8
9514 1404 393
Answer:
B. 6.8
Step-by-step explanation:
The drawing measure can be found using the proportion ...
drawing/actual = 2 in/(5 ft) = x/(17 ft)
Multiplying by 17 ft gives ...
x = (2 in)(17/5) = 6.8 in
The drawing of the kitchen will be 6.8 inches.
