Answer:

the problem is asking you to divide (16-2) by (7-5)

14 / 2

The answer is 7

Step-by-step explanation:

The expression for the calculation of the quotient of 16 minus 2 and 7 minus 5 is (16-2)/(7-5) and the solution of this equation is 7.

Quotient is the resultant number which is obtained by dividing a number with another. Let a number is divided by number b. Then the quotient of these two number will be,

[tex]q=\dfrac{a}{b}[/tex]

Here, (a, b) are the real numbers.

The expression for the calculation of the quotient of 16 minus 2 and 7 minus 5 has to be written.

Let n, is the required expression. Thus,

[tex]n=\dfrac{16-2}{7-5}[/tex]

Solve it further,

[tex]n=\dfrac{14}{2}\\n=7[/tex]

Thus, the expression for the calculation of the quotient of 16 minus 2 and 7 minus 5 is (16-2)/(7-5) and the solution of this equation is 7.

Answer:

[tex] \frac{7}{9} \times 5 \frac{2}{5} \\ = 4 \frac{1}{5} [/tex]

The result of 7/9 × 5 2/5 as a fraction is 21/5.

Given the expression in the question:

7/9 × 5 2/5

To multiply 7/9 by 5 2/5 as a fraction, first, convert the mixed number 5 2/5 to an improper fraction.

5 2/5 ⇒ ( 5 × 5 + 2 )/5 = ( 25 + 2 )/5 = 27/5

Hence, we have:

7/9 × 27/5

To multiply fractions, multiply the numerators together and then multiply the denominators together:

( 7 × 27 )/( 9 × 5 )

( 189 )/( 9 × 5 )

189/45

Simplifying, we get:

21/5

Therefore, the simplified form is 21/5.

Answer:

By the time she achieves her 26 mile goal Andrea will have run 176 miles.

Step-by-step explanation:

Since Andrea runs 4 miles every day, but she wants to increase her distance in order to run a 26 mile marathon and she decides to add 2 miles each day to her distance until she achieves her goal, to determine, if she starts with 6 miles today, how many miles will she have run in total, by the time she achieves her 26 mile goal the following calculation should be performed:

6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 + 22 + 24 + 26 = X

14 + 22 + 30 + 38 + 46 + 26 = X

36 + 68 + 72 = X

36 + 140 = X

176 = X

So, by the time she achieves her 26 mile goal Andrea will have run 176 miles.

Answer:

  (b) ΔPQR ~ Δ STR, PR = 16, SR = 12

Step-by-step explanation:

The similar triangles are ...

  ΔPQR ~ ΔSTR . . . . by AA similarity: S ≅ P; ∠SRT ≅ ∠PRQ

Corresponding sides are proportional, so we have ...

  PR/PQ = SR/ST

  (x +1)/8 = (x -3)/6

  3(x +1) = 4(x -3) . . . . . . multiply by 24

  3x +3 = 4x -12 . . . . . . . eliminate parentheses

  15 = x . . . . . . . . . . . . . . add 12-3x

Then the side lengths are ...

  PR = x+1 = 15 +1 = 16

  SR = x -3 = 15 -3 = 12

The similarity statement and side lengths match the 2nd choice.

Answer:

D) 171 cm²

Step-by-step explanation:

You don’t actually need to decompose it.  You could just do it as a trapezoid:

(15+23)/2=19

19x9=171

If you want to decompose it into 2 triangles and a rectangle:

10=15x9=135

1/2(3)(9)=13.5

1/2(5)(9)=22.5

135+13.5+22.5=171 also

Given:

A straight line goes through (-2,1), (0,0), and (2,-1).

To find:

The slope of the given line.

Solution:

Slope formula

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Consider any two points from the given points.

The line goes through (-2,1) and (0,0). So, the slope of the line is

[tex]m=\dfrac{0-1}{0-(-2)}[/tex]

[tex]m=\dfrac{-1}{2}[/tex]

Therefore, the slope of the line is [tex]m=-\dfrac{1}{2}[/tex].

Step-by-step explanation:

8 × 9 = 72

33 + 72 = 105

The answer is 105

31 - 20 = 11

11 × 3 = 33

The answer is 33

102 - 6 = 8 - 5

102 - 6 = 96

96 = 8 - 5

8 - 5 = 3

96 = 3

93 = 3 is false so therefor, this equation has no solution.

4th Equation:

102 = 12 + 4 × 7 - 2

4 × 7 = 28

102 = 12 + 28 - 2

12 + 28 = 40

102 = 40 - 2

40 - 2 = 38

102 = 38

102 = 38 is false so, it means that this equation has no solution.

Answer:

27.09% of the panthers weigh less than 76 pounds

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 82 pounds and a standard deviation of 9.8 pounds.

This means that [tex]\mu = 82, \sigma = 9.8[/tex]

What percent of the panthers weigh less than 76 pounds?

The proportion is the pvalue of Z when X = 76. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{76 - 82}{9.8}[/tex]

[tex]Z = -0.61[/tex]

[tex]Z = -0.61[/tex] has a pvalue of 0.2709

0.2709*100% = 27.09%

27.09% of the panthers weigh less than 76 pounds

Answer:

5.5×5.5=30.5

we rounded 30.25 in nearest tenth it becomes 30

Answer:

C.] 5.5

Step-by-step explanation:

It is mentioned that the number was multiplied by the number itself.

Let's take 'x' as the number. It was multiplied by itself and the product is 30. So the equation will be:

x × x = 30

[tex]x^{2}[/tex] = 30

x = [tex]\sqrt{30}[/tex]

x = 5.47 = 5.5 (to the nearest tenth)
