Answer:

B - 593.8 ft2

Step-by-step explanation:

I also just finish the quiz and got the question right.

To find the base: 10 x 18 = 180

There are 4 lateral face, two each are conguent:

18 x 14.1 = 253.8

253.8 divided by 2 = 126.9

126.9 x 2 = 253.8

Other conguent sides:

10 x 16 = 160

160 divided by 2 = 80

80 x 2 = 160

Finally: 180 + 253.8 + 160 = 593.8 ft2

Answer:

a = 51
b = 51 (??not so sure)
c = 20 cents

Step-by-step explanation:

a) 25 x 408 = 10200
10200 ÷ 200 = 51 square ft is one one roll.

b) the surface area of an average gift is 51 sq ft (?)

c) 40 ÷ 200 = 0.2
each roll costs $40 dollars. each roll can wrap 200 gifts so 40 ÷ 200 = $0.20/ 20 cents

Answer:

-25

Step-by-step explanation:

f(-12) means x = -12

so you just plug it in the equation and solve for x

$f(x) = 3(-12)+11\\f(x) = -36+11\\f(x) = -25$

Clifton ran 6 miles in 39 minutes. At this rate, how much time Clifton takes to run one mile?

slavikrds [6]

Option C: Clifton takes 6 minutes and 30 seconds to run one mile.

Explanation:

Given that Clifton ran 6 miles in 39 minutes.

We need to determine the time it takes for Clifton to run one mile.

To determine the time that it takes for Clifton to run one mile, we shall divide 39 minutes by 6 miles.

Thus, we have,

$\frac{39 \ minutes}{6 \ miles}=6.5 \ minutes$

$=(6+0.5) \ minutes$ -------(1)

To convert 0.5 minutes to seconds, let us multiply the value by 60.

Thus, we have,

$0.5 \times 60= 30 \ seconds$

Thus, substituting in equation (1), we have,

$(6+0.5) \ minutes= 6 \ minutes \ and \ 30 \ seconds$

Therefore, it takes 6 minutes and 30 seconds for Clifton to run one mile.

Hence, Option C is the correct answer.
