Answer:

1728

Step-by-step explanation:

2 $\pi$ r h

2 $\pi$ (11) × 14

968

B= $\pi r^{2}$

B= $\pi$ 11^2 =121 $\pi$

S=2 $\pi$ rh + 2 $\pi r^{2}$

S=968 +2 x 121

S=968 +242 $\pi$ = 1728

9=ln(x+7) | Solve for x

frez [133]

Remember that ln= $log_{e}$
and

$log_{a}x=y$ means $a^y=x$
convert
ln(x+7)=9 means
e^(9)=x+7
minus 7 from both sides
e^9-7=x
use calculator to evaluate
8096.08=x aprox

the perimeter of a pool table is 30 ft.The table is twice as long as it is wide.what is the length of the pool table.

noname [10]

Perimeter is legnth +legnth + width + width or
P=2L+2W

L=2W
subsitute L=2W for L in P=2L+2W

P=2(2W)+2W
P=4W+2W
P=6W

we know that Perimiter=30 so
30=6W
divide both sides by 6
5=Width

subsitute W=5 for W in L=2W
L=2(5)
L=10

to check
10=2(10)+2(5)
30=20+10
30=30
checks

Legnght=10
Width=5

Lisa [10]

Answer:

it denotes existence of additive inverse i.e. option A is correct

Explanation:

In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite (number), sign change, and negation. For a real number, it reverses its sign: the opposite to a positive number is negative, and the opposite to a negative number is positive.

Angles A and B are complementary. Angle A has a measure of 2X - 8. Angle B

harkovskaia [24]

Answer:

Step-by-step explanation:

180 = 2x-8 + 36

152 = 2x

76 = x

now plug it into the given expression

∠A = 2x-8

∠A = 2(76) -8

∠A = 152-8

∠A = 144 °
