Consider the original parallelogram and the reduction.
A parallelogram with side lengths 18 centimeters and 45 centimeters. A second parallelogram with side lengths A and 5 centimeters.
Figures not drawn to scale.
What is the length of side A in the new parallelogram?
2 cm
9 cm
90 cm
162 cm
i believe it is a but someone pls confirm thx
I can confirm that it is A as I took the test and got 100%.
The length of side A in the new parallelogram will be [tex]2[/tex] cm.
What is Scale Factor ?Scale Factor is defined as the ratio of size of new image formed to the size of old image.
We have,
A parallelogram with side lengths [tex]18[/tex] centimeters and [tex]45[/tex] centimeters.
And,
A second parallelogram with side lengths [tex]A[/tex] and [tex]5[/tex] centimeters.
Now,
Scale Factor [tex]=\frac{size\ of\ new\ image}{size\ of\ old\ image}[/tex]
So,
Now, Comparing sides ,
We get,
Scale Factor [tex]=\frac{45}{5}=9[/tex]
i.e. the second parallelogram have Scale Factor of [tex]9[/tex].
So,
Other sides of both parallelograms will be of same Scale Factor.
i.e.
[tex]=\frac{18}{A} =9[/tex]
⇒
[tex]A=2[/tex] cm
Hence, we can say that the length of side A in the new parallelogram will be [tex]2[/tex] cm.

HELP IM SO CONFUSED about this
Answer:
180
straight
Step-by-step explanation:
Hello There
So we are given that angle a is equal to 11x + 37
we are also given that x = 13
because we are given the value of x we can simply find the measure of angle A by plugging in 13 to x into the expression
so basically angle A = 11 ( 13 ) + 37
11 * 13 = 143
143 + 37 = 180
now we want to classify the angle
here are the angle types and what they measure
(let x be measure of angle)
acute 0 < x < 90
so an acute angle has a measure of less than 90 degrees
the measure of angle A is 180 degrees so we can clarify that it is not an acute angle
right angle x = 90
a right angle has a measure of 90 degrees
angle a has a measure of 180 degrees therefore it is not a right angle
obtuse angle 90 < x < 180
the measure of an obtuse angle must be less than 180
because angle a = 180 it is not classified as an obtuse angle
straight angle x = 180
the measure of a straight angle is 180 degrees
angle a measure 180 degrees so we can conclude that angle a is a straight angle
45 percent of what is 27
Answer:
x = 60
Step-by-step explanation:
We have, 45% • x = 27
or,
45 /100 • x = 27
Multiplying both sides by 100 and dividing both sides by 45,
we have x = 27 • 100/ 45
x = 60

Paul wants to visit his aunt who lives 300 miles away from his house. He drives his car at about 50 miles an hour. If X represents the time spent driving and why represents the distance from his aunts house which scatterplot could represent the situation
Answer:
It would take 6 hours.
An equation for that could be: 50x = 300 (X is how long it would take)
So 50 mph• X (time spent) = 300 miles
You didn't give me any scatterplots to look at so I can't help you with that sorry

Cups of flour = 13
Cups of cinnamon = 25
Number of cinnamon cups needed for each cup of flour :
Number of cinnamon cups / number of cups of flour
25 / 13
= 1.923
Hence, about 1.92 cups of cinnamon is needed per cup of flour

3 5 of the first group are right-handed. 80% of the second group are right-handed. What fraction of the class is right-handed?
Answer:
7/10
Step-by-step explanation:
To make things simple, let's turn 80% into a fraction, 8/10. To get a common denominator let's turn 8/10 into 4/5. Since they are both of equal size, the first group would have 2/5 left-handed people and the second 1/5 left-handed people. Let's imagine that each group has 5 people in it. There would be 10 people in total. There is 1 person for each fifth so we can add now. 4 + 3 = 7 right handed people. To check, 2 + 1 = 3 and 3 + 7 = 10. so 7/10 of the class is right-handed.

Answer:
c
Step-by-step explanation:
[tex]sin = \frac{opposite}{hypotenuse}[/tex]
it wants us to find sin a
the opposite of a is 24 and the hypotenuse is 26
so sin A = 24/26
[tex]cos = \frac{adjacent}{hypotenuse}[/tex]
it wants us to find cos a
the adjacent of a is 10 and the hypotenuse is 26
so cos A = 10/26

6/12+8/12+9/12=23/12=1 11/12
Answer:
D. 1 11/12
Step-by-step explanation:
Let's set up our common denominator first. To do this we need to find a number divisible by 2, 3, and 4.
Multiply 3 by 4 and you'll come out with 12. 12 is divisible by 2.
Now, multiply your fractions by the numbers they need to get the denominator to 12.
1/2 x 6/6 = 6/12
2/3 x 4/4 = 8/12
3/4 x 3/3 = 9/12
Add your numerators.
6 + 8 + 9 = 23.
Your fraction should look like 23/12.
Subtract 12 from 23 and you should get 11. Because 12 equals a whole, we can go ahead and put one.
