The width of a rectangle room is 80 percent of its length. WHat is the area of the room?
Answer:
180 squared ft
Step-by-step explanation
80% = 80/100 = 40/50 = 4/5
L = 15
W= 4/5 of 15 = 12
Area = LxW
Area = 15x12 = 180 squared ft

Answer:
All three are similar!
Step-by-step explanation:
If you get that right, follow Sammy Revv on Spotify!
Answer:
The three of them are similar.
Step-by-step explanation:
1- Triangle A and Triangle B have two same angles, 37° and 47°, which means the two angles are congruent. According to the Angle Angle Theorem (AA), in two triangles, if two pairs of corresponding angles are congruent, then the triangles are similar.
2- First, place both triangles correctly. When you do it, you'll notice that 24≅12, 32≅16, and 9≅4.5:
24/12 = 2 ✓ 32/16 = 2 ✓ 9/4.5 = 2 ✓According to Side-Side-Side Theorem (SSS), if the measures of corresponding sides are known, then their proportionality can be calculated. If all three pairs are in proportion, then the triangles are similar.
3- Here, the triangle shows in each one two different angles, sharing only one which is 55°. To know if they are congruent, you can add the two different angles that show both triangles, 72° and 53°, with the 55°. If it gives 180, it means the can be congruent:
55°+72°+53 = 180° ✓Rewrite the following equation in standard form. y = 2/5x
Answer:
2x - 5y = 0

You invest $1,900 at 4% and it's compounded semi-annually (twice a year) for 3 years. How much will your $1,900 be worth in 3 years?
Answer:
FV= $2,139.71
Step-by-step explanation:
Giving the following information:
You invest $1,900 at 4% and it's compounded semi-annually (twice a year) for 3 years.
First, we need to calculate the semiannual interest rate:
Semmi-annual interest rate= 0.04 / 2= 0.02
To calculate the future value, we need to use the following formula:
FV= PV*(1 + i)^n
PV= $1,900
i= 0.02
n= 2*3= 6 semesters
FV= 1,900*(1.02^6)
FV= $2,139.71

Find the surface area of this rectangular prism. Be sure to include the correct unit in your answer.
The length of a rectangular garden is four times its width (w), plus 3 feet. Which expression represents the garden's length in feet?
Answer: 4w + 3
Step-by-step explanation:
Since the width is represented by w.
The expression for the length of the rectangular garden which is four times its width (w), plus 3 feet will be:
= (4 × w) + 3
= 4w + 3
For example, if the width is 5feet, the length will be:
= 4w + 3
= 4(5) + 3
= 20 + 3
= 23 feet.

PLEASE I REALLY NEED HELP PLEASE!!
Answer:
I think the answer is B.
Step-by-step explanation:
Solve for x. please i need know
Answer:
x = 18
Step-by-step explanation:
Vertically opposite angles are equal.
x + x + x + 90 = 144
3x + 90 = 144
Subtract 90 from both sides
3x = 144 - 90
3x = 54
Divide both sides by 3
x = 54/3
x = 18

how many 1/2 cups to make 3/4 of a cup?
We are required 1.5 half cups to form the required fraction of a cup.
What is a fraction?The upper part of a fraction is numerator and the lower part is denominator.
How to find the fraction?We are told to make 3/4 of a cup from1/2 of cup so let the number of times we need half of a cup be x
So
1/2 * x=3/4
x=3/2 which means 1.5
So we need 1.5 times the half cup to make 3/4 of a cup.
