Answer:

If your asking what is 4 x 8 its 32 or are you asking for 8 divided by 4 which is 2 or are you asking if 13) 45 is 9 times as many as 5. 14) 15 is 5 times as many as 3 . 15) 4 times as many as 7 is 28 . 16) 24 is 3 times as many as 8 .

Step-by-step explanation:

8 x 4 : 8 + 8 + 8 + 8 = 32 or 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 = 32

8 divided by 4 : 4 x 2 is 8 so we already have 4 and 8 so the answer is 2

Answer:

$5^{12}$

Step-by-step explanation:

Lets say there's a number 'x' and there's an expression $(x^a)^b$ where 'a' & 'b' are also numbers , <u>the simplified form of the expression is </u> $x^{a \times b}$ <u>.</u>

So ,

$(5^4)^3 = 5^{4 \times 3} = 5^{12}$

a small silver dollar pancake served at the restaurant has a circumference of 2*pi inches. A regular pancake has a circumference

Ludmilka [50]

Pi = 3.14

2*3.14 = 6.28
4*3.14 = 12.56

area = pi [ C/ (2pi)] ^2
C= circumference

area of small = 3.14 (6.28/6.28)^2 =3.14
area of regular = 3.14 (12.56/6.28)^2 = 12.56

12.56/3.14 = 4

The regular pancake is 4 times the area.

A circle with a circumference of 51 inches to find the area

Kaylis [27]

$\textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ C=51 \end{cases}\implies 51=2\pi r\implies \boxed{\cfrac{51}{2\pi }=r} \\\\[-0.35em] ~\dotfill\\\\ \textit{area of a circle}\\\\ A=\pi r^2\qquad \implies A=\pi \left( \cfrac{51}{2\pi } \right)^2\implies A=\cfrac{51^2}{2^2\pi }\implies A\approx 206.98$

Or what value of x does 4x=(1/8)^x+5?<br> –15<br> –3<br> 3<br> 15

liq [111]

Answer:

Step-by-step explanation:

$4^x=\left(\dfrac{1}{8}\right)^{x+5}\qquad\text{use}\ a^{-1}=\dfrac{1}{a}\\\\4^x=(8^{-1})^{x+5}\\\\(2^2)^x=\bigg((2^3)^{-1}\bigg)^{x+5}\qquad\text{use}\ (a^n)^m=a^{nm}\\\\2^{2x}=2^{-3(x+5)}\iff2x=-3(x+5)\qquad\text{use the distributive property}\\\\2x=-3x-15\qquad\text{add}\ 3x\ \text{to both sides}\\\\5x=-15\qquad\text{divide both sides by 5}\\\\x=-3$

Which equation can be used to find the area of the of the trapezoid?

Leto [7]

Answer:

C) 1/2(15 +23)(9)

Step-by-step explanation:

The formula for the area of a trapezoid in terms of base lengths b1 and b2 and height h is ...

... A = 1/2(b1 +b2)h

Substituting the values shown in the figure, this becomes ...

... A = 1/2(15 +23)(9) . . . . . matches selection C
