Isn't it 5? x=5 cause the model's height is 4 less than the width so like if the actual width is 9 than the height is 4 smaller
Answer:
divide the figure into two parts.
area of triangle = 1/2×base×height
area of triangle = 1/2×3×3
area pf triangle = 4.5 units²
area of square = side²
area of square = 3²
area of square = 9unit²
Answer:
z^ {8/5}
Step-by-step explanation:
Answer:
The length of the diagonal support is 69 feet.
Step-by-step explanation:
Dimensions of the box: length = 6 feet
width = 5 feet
height = 8 feet
The diagonal support relates with the diagonal of the base and the height.
From the base of the box, let the length of its diagonal be represented by x. Applying Pythagoras theorem;
= +
= +
= 36 + 25
= 61
x =
= 7.81
let the length of the diagonal support be represented by l. So that;
= +
= +
= + 64
l =
= 61 + 8
= 69
Thus, the length of the diagonal support is 69 feet.
Given:
15% of its height each day
27 inches on day 10.
How tall was it yesterday?
27 represents 115% of the height yesterday. So we divided 27 by 115% to get yesterdays height.
27 ÷ 115% = 23.48 inches.
The plant was 23.48 inches tall yesterday.
To check:
23.48 x 15% = 3.52 inches
23.48 + 3.52 = 27 inches
