ABC ~ XYZ. The ratio of their areas is 25/16. If XY has a length of 40, what is the length of AB?
answer ASAP please !!!!
Answer:
62.5
Step-by-step explanation:
From the question, we ware told that triangle ABC is similar to XYZ
Hence Aabc/Axyz = AB/XY
Substitute the given values
25/16 = AB/40
Cross multiply
16AB = 40 * 25
16AB = 1000
AB = 62.5
Hence the length of AB is 62.5

Answer:
Step-by-step explanation:
you know the sum of the angles in a parallelogram is 360 degrees
you have an angle that is 44, the Y angle is also 44 (opposite angles are equal)
360-(44+44)=360-88=272 is the sum of the angle x and its opposite
272/2=136
x=136
When should you use the quotient of powers property?
Answer:
As well as we could multiply powers we can divide powers. This is an example of the quotient of powers property and tells us that when you divide powers with the same base you just have to subtract the exponents. When you raise a quotient to a power you raise both the numerator and the denominator to the power.

A baker made 5 pounds of dough.He used 7/9 of the dough to make sandwich rolls. how many pounds of dough was left over?
EASY MATH HALP
Answer:
Since he USES 4/9th of the dough, what is left is 1-4/9=9/9-4/9=5/9 In math, the word 'of' can translate to 'multiplied by' therefore 5/9 OF the 5pounds of douch left can translate to: 5/9*5=25/9 pounds of dough left (about 2.7 pounds)
Write an equation of the line through the point (-3,-8) and perpendicular to the line y=-7.
A. X=-3
C. y=
b. X=-8
d. y=-8
Answer:
A
Step-by-step explanation:
y = - 7 is a horizontal line parallel to the x- axis.
A line perpendicular to it must therefore be a vertical line parallel to the y- axis with equation
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (- 3, - 8) with x- coordinate - 3, then
x = - 3 ← equation of perpendicular line

Answer:
for 6: -2x+30
I dont know for # 8
Step-by-step explanation:
to distribute, you have to multiply -3 by x and -10.
-3(x) - -3(10) + x =
-3x + 30 + x:
then you have to add common terms
-3x + x = -2x
then replace that in your equation to get:

Convert 3/8 to a decimal and percent.
Answer:
0.375
37.5%
Step-by-step explanation:
Answer:
Decimal o.375
Percent 37.5 %
What percent said red, blue, or yellow?
Answer:
1 a = 70%
b 6.5 times
c green = 16%
2. ????? Very poorly worded question
2. a 54%
b. 46%
c. 70%
d. 27%
Step-by-step explanation:
1. Students in a class were asked to tell their favorite color.
a. What percent said red, blue, or yellow? __% said red, blue, or yellow.
red is .26
blue is .40
yellow is .04
---------------------
.70 = 70 %
b. How many times more students said red than yellow?
red .26
yellow is .04
.26/.04 = 6.5 times
c. What percent of students said green? __% said green.
The circle must total 100 %
Red + blue + yellow + purple + green = 100
26+ 40 + 4 + 14 + green = 100
84 + green = 100
Subtract 84 from each side
84-84 + green = 100-84
green = 16
2. Which two methods could be used to find the percent of students who said green?
We can either convert the percents to decimals or the decimals to percents
The total percents must equal 100%
The total decimal must equal 1
a. Find the sum of the percents given in the circle graph.
If they only want the ones written on the graph as percents
(14+40) = 54%
b. Find the sum of the percent forms of the numbers given in the circle graph. Subtract the result from 100%.
100 - 54% = 46%
c. Find the sum of the decimal forms of the numbers given in the circle graph. Subtract that sum from 1. Change the result to a percent.
.26+.04 = .3
1-.3 = .7
70%
d. Find the sum of half of the percents given in the circle graph. Subtract that total from 50%.
1/2 (46%) = 23%
50 -23 = 27%

Step-by-step explanation:
From 90 apples to 75 apples Round to nearest percent
The percentage decrease of the apples will be 17%.
How to calculate the percentage?A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.
The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.
From 90 apples to 75 apples, the percentage decrease will be:
= (90 - 75) / 90 × 100
= 15 / 90 × 100
= 1/6 × 100
= 17%
