Tom decides to paint one wall in his room green. Use the dimensions below to calculate the area of the this wall.

Anton [14]

Option C:

Area of the wall $=94\frac{15}{16}$ square feet

Solution:

Length of the wall = $12 \frac{1}{4}$ feet

Width of the wall = $7 \frac{3}{4}$ feet

Area of the wall = length × width

$$=12 \frac{1}{4}\times 7 \frac{3}{4}$

Convert mixed fraction into improper fraction.

$$=\frac{12 \times 4+1}{4}\times \frac{7\times 4+3}{4}$

$$=\frac{49}{4}\times \frac{31}{4}$

$$=\frac{1519}{16}$

Convert improper fraction into mixed fraction.

$$=94\frac{15}{16}$

Area of the wall $=94\frac{15}{16}$ square feet

Option C is the correct answer.

Three numbers add up to 210. The second number is 10 more than the first and the third number is 3 times the first. Find the num

svp [43]

Answer:

I. First number, a = 40.

II. Second number, b = 50.

III. Third number, c = 120.

Step-by-step explanation:

Let the three numbers be a, b and c respectively.

Given the following data;

Translating the word problem into an algebraic equation, we have;

a + b + c = 210

b = a + 10

c = 3a

Substituting the value of b and c into the equation, we have;

a + a + 10 + 3a = 210

5a + 10 = 210

5a = 210 - 10

5a = 200

a = 200/5

a = 40

To find the value of b;

b = a + 10

b = 40 + 10

b = 50

To find c

c = 3a

c = 3*40

c = 120
