A rectangular room measures 15 feet by 20 feet. The ceiling is 9 feet high. What is the total area of the four walls? (to the ne

frozen [14]

Answer:

Answer:

825 feet of area of the wall required to be painted.

Explanation:

Given:

Length of the room = 15 feet

Width of the room =12 feet

Height of the room = 9-foot

Size of the door= 3 feet x 7 feet

To find:

The area of the walls that requirespainted=?

Solution:

We know that,

Area of walls that need paint = total surface area of room – area of door that doesn’t need paint…………(1)

Finding the Total area of the room:

room is cuboidal shape,

Then, its total surface area = 2(lb + bh + hl)

Where

h is height,

l is length,

b is width

Substituting the values,

Total surface area = 2(15 x 12 + 12 5 9 + 9 x 15)

Total surface area = 2(180+108+135)

Total surface area = 2( 423)

Total surface area = = 846 feet…………..(2)

Finding the area of the door:

Area of door = area of rectangle = length x width

Substituting the values,

area of door= 3 x 7 = 21 feet……………(3)

Substituting (2) and (3) in (1)

Area that is require paint = 846 – 21 = 825 feet

A pizza had 9/10 left before Lucas ate 4/5 of the pizza. How much pizza is left over?

Allushta [10]

Step-by-step explanation:

always try to bring fractions you need to compare to the same denominator (bottom number).

we have 9/10 of the pizza left.

then 4/5 if the pizza are eaten.

how to compare 9/10 with 4/5 ?

by bringing 4/5 also to a fraction of 10ths.

what do I need to multiply 5 with to get 10 ?

right, 2.

since we don't want to change the overall value of the original fraction, we need to multiply both levels (numerator and denominator) by that same factor :

4/5 × 2/2 = 8/10

aha !

that we can compare with 9/10.

so, when Lucas ate 4/5 (= 8/10) of the pizza, when there was originally 9/10 left, then we have 1/10 of the pizza left.

Can you show the working out as well please?

Airida [17]

Answer:

BC = 60

Step-by-step explanation:

3X + X = 80 <---- X = BC

3X + X = 4X

4X = 80 <---- DIVIDE BOTH SIDES BY 4

4X ÷ 4 = X

80 ÷ 4 = 20

20 × 3 = 60

6 cups of flour is needed for a big batch of cookies that uses 9 cups of oatmeal

Step-by-step explanation:

For 3 cups of oatmeal 2 cups of flour is required.

We need to find how much flour is needed for 9 cups of oatmeal.

Solving by using Unitary Method

3 cups of oatmeal require flour = 2 cups

1 cup of oatmeal require flour = $\frac{2}{3}$

9 cups of oatmeal require flour = $\frac{2}{3}*9\\$

= $6$

So, 6 cups of flour is needed for a big batch of cookies that uses 9 cups of oatmeal
