Which system of equations could be used to determine how many of each coin you have

kirza4 [7]

<h3>Answer: Choice A</h3>

0.10d + 0.05n = 2.25

d = 2n

================================================

Explanation:

n = number of nickels

d = number of dimes

we have twice as many dimes as nickels, so we could have something like 18 dimes and 9 nickels. Algebraically we would write d = 18 and n = 9. The equation that fits this is d = 2n. The answer is between A and B at this point.

We rule out choice B since the 0.05d is incorrect. It should be 0.10d to represent the total value of all the dimes.

Choice A is correct

d = number of dimes

0.10d = value of all the dimes in dollars

n = number of nickels

0.05n = value of all the nickels in dollars

0.10d + 0.05n = total value from both coins combined

2.25 = total value from both coins combined

0.10d + 0.05n = 2.25

The average weight of full-grown beef cows is 1,470 pounds with a standard deviation of 230 pounds. if the weights are normally

creativ13 [48]

Answer: The percentile is 89

Step-by-step explanation:

This question can be solved using concept for t tables

In a normal distribution the curve. $\mu= 1470 , \sigma = 230, x=1750$

The relationship between z score, mean and standard deviation is given by

$x = \mu+z\sigma$

So the z value according to this is given by the formula

$1750=1470+z(230)\\ z=\frac{280}{230} \\\\z = 1.217$

From the z table we can infer that p value for z=+1.217 is 88.82

So 1750 is 89th percentile

Write an expression to represent: "the difference of 8 squared and a number"

Gnom [1K]

Answer:

The expression is (64 - x).

Step-by-step explanation:

The statement is:

"the difference of 8 squared and a number"

Let the number be denoted by <em>x</em>.

The value of 8 squared is:

$8^{2}=8\times 8\\$

$=64$

Then the expression for the provided statement is:

(64 - x)

Thus, the expression is (64 - x).
