Answer:

Step-by-step explanation:

Factorize all the numbers in numerator and denominator

16 = 2*2*2*2

125 = 5 *5 *5

\frac{a^{m}}{a^{n}}=a^{m-n},  where m >n

\frac{5^{4}*7^{5}*2^{8}}{16*125*7^{3}}=\frac{5^{4}*7^{5}*2^{8}}{2^{4}*5^{3}*7^{3}}\\\\\\=5^{(4-3)}*7^{(5-3)}*2^{(8-4)}\\\\\\=5^1*7^2*2^{4}

Answer:

98,000

Step-by-step explanation:

5^{4} *7^{5}* 2^{8}/16*125*7^{3}

=5^{4} * 7^{5}* 2^{8}  /2^{4} *5^{3} *7^{3}

=5^{4-1} *7^{5-3} *2^{8-4}

=5^{3} *7^{2} *2^{4}

=125*49*16

=98000

ANSWER ASAP !! NEED HELP ASAP
liq [111]

Answer:

130

Step-by-step explanation:

The two angles add up to be 180 degrees, so you could find the value of the second angle to be 110 degrees, but it is asking for the x value so you would choose 130 since when you subtract 20 from 130 you get 110.

A chef uses 4 3/4 cups of broth for 10 servings of soup. How much broth is used in one serving of soup? Let x represent the amou
Margarita [4]
Convert 4 and 3/4 into an improper fraction: 19/4. Then, divide 19/4 into 10, but to divide fractions, you multiply by the reciprocal. So: 19/4•1/10=19/40. So the chef uses 19/40 cup of broth in each serving.

What is the area of the figure?? HELP PLS!!
Alchen [17]
Hi!

I've included an image showing the shape divided into 3 rectangles. We're going to find the area of each rectangle.

To find the area of a rectangle, multiply the length times the width. 

The red rectangle:

8 · 9 = 72
The area of the red rectangle is 72in.

The orange rectangles:

The orange rectangles have the same area. 
10 · 3 = 30
30 + 30 = 60
The area of both orange rectangles is 60in.

72 + 60 = 132

The answer is 132 square inches.

Hope this helps! :)

onsider the following limit of Riemann sums of a function f on​ [a,b]. Identify f and express the limit as a definite integral.
sveta [45]

Answer:

The solution is given as \int_{6}^{10} x^4dx

Step-by-step explanation:

It is given that

\lim_{\Delta \to 0} \sum_{k=1}^{n}(x_{k}^{*})^4\Delta x_{k}                 \, \,\,\,\,\,\,\,\,\, [6, 10]

As

\int_{a}^{b} F(x)dx=\lim_{\Delta \to 0} \sum_{k=1}^{n}(x_{k}^{*})\Delta x_{k}

where a and b are the lower and upper limits of the bound respectively.

On comparison it is observed that

  • a=6
  • b=10
  • F(x)= x^4

So the equation is given as

\lim_{\Delta \to 0} \sum_{k=1}^{n}(x_{k}^{*})^4\Delta x_{k}\\=\int_{6}^{10} x^4dx

So the solution is given as \int_{6}^{10} x^4dx
