Answer 1

Answer: 1)
The formula for the area of a rectangle is:

A=l*w

Since we know both the length, 15, and the area, 150, we can solve for the width.

150=15*w
Divide both sides by 15
10=w

The width is 10ft

Answer= The Dimensions of the rug are 10ft by 15ft

2)
The formula for the area of a rectangle is:
A=l*w

To solve for this problem, we need to subtract the area of the rug, from the area of the room.

A(room)-A(rug)=A(remaining)

We still don't know the area of the entire room, so lets solve for that

A(room)=l*w
A(room)=25*20
A(room)=500sq ft

Now we can search for the remaining area...

A(room)-A(rug)=A(remaining)
500-150=
350 sqft

Answer=350 sqft

Heather is trying to decrease the amount of toys that Oliver has. Originally, he had 55 toys in his room and now he only has 30. By what percentage did Heather decrease the amount of toys?

Answers

Answer: 45.45%

Step-by-step explanation:

Given: The number of toys in Heather's room before = 55

The number of toys now in the room = 30

Now, the decrease in the toys = $55-30=25$

We know that the percent decrease is given by ;-

$\frac{\text{Decrease in amount}}{\text{amount before}}*100$

$\n=(25)/(55)*100=45.4545\approx45.45\%$

Hence, Heather decrease the amount of toys by 45.45% .

25/55 = x/100, so I think it is 45% Decreased.

a triangular shape has an area of 70 square inches the height is 8 and three fourths write and solve an equation to find the length of the base

Answers

Area formula of a triangle is:
A = $(1)/(2) bh$
We know the area and the height, so substitute to find the base

A = 70 m²
h = 8.75 m or $8 (3)/(4)$ m (its the same thing)

70 = $(1)/(2)$ × b × 8.75
70 = 4.375b
Divide by 4.375 on either sides to isolate b
$(70)/(4.375) = (4.375b)/(4.375)$
4.375 and 4.375 cancels out

16 m = b

The base of this triangle is 16 m

Jade ran six times around her neighborhood to complete a total of one mile. How many times will she need to run to complete 5/6 of a mile

Answers

-- 6 laps around the neighborhood = 1 mile

-- Each lap = 1/6 of a mile.

-- 5/6 of a mile requires 5 laps.

==========================================

Using a proportion:

   ('L' laps) / (5/6 mile) = (6 laps) / (1 mile)

Cross-multiply the proportion:

   L lap-mile = (6) x (5/6) lap-mile

Divide each side by mile :

   L lap = (6) x (5/6) lap = 5 lap

the answer would be 5 laps because 1 miles= 6 laps and she needs to run 1 less then that.

Solve the equation t/4 = 16

Answers

First you do you opposite of dividing because of the 4 dividing the t. Since the opposite of division is multiplication you multiply and the 4's cancel each other out. So now you have t=16 but what you do to one side you do to the other so you have to * 4 the 16 giving you 64. so now you have 4 = 64. To check you have to divide 64 by 4 giving you 16 once more showing its correct.

t = 4 * 16;
t = 64;

The solution is correct because 64 / 4 = 16;

The cone shown has a radius of 6 inches and a slant height of 10 inches. What is the total surface area of the cone? Use 3.14 to approximate pi. Round your answer to the nearest whole number.

Answers

To find the total surface area, we can use the formula
A=3.14*r*l + 3.14*r^2
In this case, the radius is 6 and the slant height
Therefore, the equation to find the surface area is:
A = 3.14 * 6 * 10 + 3.14 *6^2
When simplified, we find that the surface area is about 301.44
Therefore, the answer rounded to the nearest whole is 301

Hope this helped!! :D

A=π•r•l+π•r²
A=3.14•6•10+3.14•6²
A=188.4+113.04
A=301.44 =301
