Zarrin [17]
Two equations 

let c the calories in carrot
let h the  <span>calories in </span><span>hershey's kisses
</span><span>

4c + 8h = 230                eq 1</span>
10 c + 7 h = 263             eq 2  


to solve the solution  we multiply eq  1 by 10 
we multiply <span>eq  2 by 4
</span>
40 c + 80 h =  2300
40c + 28 h = 1052 

we subtract the two equations we get
 52  h = 1248 

h= 24 

and so in replacing h = 24 in the equation we get c = 9.5

Answer:

Given expression is equal to  1/32

Step-by-step explanation:

Given that:

= 4^(-5/2)

To eliminate "-" sign we will invert the fraction as follows:

= (1/4)^ 5/2

Or it can be written as:

= =\sqrt{(1/4)^5} \\=\sqrt{1/1024} \\=1/32

This is the simplified expression.

i hope it will help you!

What is the greatest common factor of 90, 126, 180 and 990?
mylen [45]

9514 1404 393

Answer:

  18

Step-by-step explanation:

90 = 18·5

126 = 18·7

180 = 18·10

990 = 18·55

The greatest common factor of these numbers is 18.

__

<em>Comment on the GCF</em>

It can be useful to know Euclid's algorithm for finding the GCF:

  1. Determine the remainder from dividing the larger number by the smaller.
  2. If the remainder is zero, the smaller number is the GCF. If the remainder is non-zero, use it to replace the larger number and repeat from step 1.

For example, 126 mod 90 = 36; 90 mod 36 = 18; 36 mod 18 = 0, so 18 is the GCF of 126 and 90. (The modulo function 'mod' returns the remainder from division.)

5.69÷7 you can round to nearest hundredth
pogonyaev
The answer would be .81 becuase you can't round the 1 up to 2 becuase the number in the thousandths place is not above 5. 
Hope this helps!!
