7 is “what was our opinion of the experiment and results?”
8 is “random”
Answer:
12 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated using the formula
A = h(a + b)
where h is the height and a, b the parallel bases
here h = 3, a = 3 and b = 5, hence
A = × 3 (3 + 5) = 1.5 × 8 = 12 cm²
Answer:
6.5 Gallons
Step-by-step explanation:
288 miles / 12 gallons = 24 mpg
156 miles / 24 mpg = 6.5 gallons
Answer:
Step-by-step explanation:
Hello, please consider the following.
m and n are the two numbers.
m + n = 24, right?
n = 2 m
We replace n in the first equation, it comes
m + 2m =24
3m = 24 = 3*8
So, m = 8 and n = 16
Thank you
Replace S with the given surface area:
2646 = 6x^2
Divide both sides by 6:
x^2 = 2646 / 6
x^2 = 441
Take square root of both sides:
x = √441
x = 21
The answer is D. 21
