Step-by-step explanation:
7+8+9=24
72/24 = 3
7X3 =21
8x3 = 24
9x3 = 27
Answer:
Step-by-step explanation:
L = W+3
perimeter = 2L+2W = 58
L+W = 29
(W+3)+W = 29
W = 13 ft
L = W+3 = 16 ft
So first, find the area of the square. 12x12= 144inches^2
Then find the area of the circle. To do this we use pi x r^2. The radius of the circle is 6 inches. Pi x 6^2 = 113.04inches^2.
144 - 113.04 = 30.6, so your answer is 30.6 inches^2
The circles circumference is worked out by using pi x d. The diameter is 12 inches, so 3.14x12 = 37.68 inches.
The squares perimeter is 12 x 4 = 48 inches.
If you round up the circumference of the circle to the nearest integer, you get 38 inches. The ratio would therefore be, 38:48, which can be rounded down to 19:24 :)

Answer:
7(1/4) = 7/4 = 1 3/4
Step-by-step explanation:
Multiplication is used to simplify repeated addition. The multiplier represents the number of times the sum includes the repeated value.
Here, the term 1/4 appears in the sum 7 times. That means we can write the equivalent expression ...
7 × 1/4 . . . . written as a multiplication expression
The product is found by multiplying the numerator of the fraction by the integer factor.
7 × 1/4 = 7/4
This improper fraction can be written as a mixed number.
7/4 = 1 3/4 . . . . the value of the sum
