To check whether the statements are correct, we need to convert cm to mm.

surface area of a cube = 6 a²
294 cm² = 6 a²
294 cm² / 6 = a²
49 cm² = a²
√49 cm² = √a²
7cm = a

1 cm = 10 mm
7 cm = 70 mm

Surface area of a cube = 6a²
= 6 * (70mm)² = 6 * 4,900mm² = 29,400mm²

<span>B. The number representing the surface area would increase.
</span><span>E. The actual surface area would stay the same.</span>

Rama09 [41]

Answer:

The answer is False,

Step-by-step explanation:

The answer is False because in some expressions if there are parentheses and there is a subtraction problem in the parentheses but there is an addition problem in front of the parentheses that does not exactly mean that you do the addition first, this is because the subtraction is inside the parentheses and so since the subtraction is in parentheses it is done fist.

The measures of two complementary angles are in the ratio 8:1. how many degrees are in the larger angle?
djverab [1.8K]
Since the measures of the two angles are in the ratio 8:1, this means the bigger angle's is 8x and the smaller angle is x. Since they are complementary, they add to 90°, so you create the equation 8x+x=90°. This can be simplified to 9x=90°. Then, you divide 90 by 9 to get 10. This means x=10. Next, you replace x with 10 to find the measure of the bigger angle. 8x10=80, so the larger angle is 80°.
