Answer:

$\frac{a}{sinA} = \frac{b}{sinB} = \frac{c}{sinC}$

$\frac{x}{sin25} = \frac{32}{sin90}$

$x = \frac{32sin25}{sin90}$

$x = 13.5$

Hope this helps! Have a great day... please mark as brainliest :0 :))

Answer:

15% markup

Step-by-step explanation:

5% markup would be $1. Since 20*5% or 20*.05=1

We can multiply it by 3 to find the percent for $3 markup. Which is 15% or 0.15

As quality control manager at a raisin manufacturing and packaging plant, you want to ensure that all the boxes of raisins you s

9966 [12]

Answer:

Step-by-step explanation:

The population average number of raisins per box is 30.

The type of statistical analysis to be run here is the inferential statistical analysis and its assumptions include normality, linearity and equality of variance.

Null hypothesis: Average number of raisins per box is 30: u = 30

Alternative hypothesis: Average number of raisins per box is not 30: u ≠ 30

To perform a two tailed single sample test, we have

z statistic = (the sample mean - hypothesized mean) / (SD/√n)

sample mean = 28.05, SD = 3.87 hypothesized mean = 30 n = 36

Thus, we have 28.05 - 30 / (3.87/√36)

= -1.95 / (3.87/6)

= -1.95 / 0.645

= -3.023

we say this is a left tailed test and use the negative z table

where -3.02 = 0.0013

To determine whether the average number of raisins per box differs from the expected 30.

Using p < 0.05, since the observed value 0.0013 is less than 0.05, we conclude the the average number of raisins per box differs from the expected 30.

Find four consecutive whole numbers whose sum is 74

Rina8888 [55]

Answer:

17, 18, 19, 20

Explanation:

Let the numbers be x, x + 1, x + 2, x + 3

Their sum is equals to 74

x + x + 1 + x + 2 + x + 3 = 74 (group the variables)

x + x + x + x + 1 + 2 + 3 = 74 (simplify)

4(x) + 6 = 74 (subtract both sides by 6)

4x = 68 (divide both sides by 4)

x = 17

Other numbers:

x + 1 = 17 + 1 = 18

x + 2 = 17 + 2 = 19

x + 3 = 17 + 3 = 20

Square root of 144 X^7 Y^5

LekaFEV [45]

The first step to solving this is to factor out the first perfect square
$\sqrt{12^{2} x^{7} y^{5} }$
now factor out the second perfect square
$\sqrt{ 12^{2} x^{6} X x y^{5} }$
then factor out the second perfect square
$\sqrt{ 12^{2} x^{6} X x y^{4} X y}$
the root of a product is equal to the product of the roots of each factor
$\sqrt{ 12^{2} }$ $\sqrt{ x^{6} }$ $\sqrt{ y^{4} }$ $\sqrt{xy}$
reduce the index of the radical and exponent with 2 of the first square root
12 $\sqrt{ x^{6} }$ $\sqrt{ y^{4} }$ $\sqrt{xy}$
reduce the index of the radical and exponent with 2 of the second square root
12x³ $\sqrt{ y^{4} }$ $\sqrt{xy}$
reduce the index of the radical and exponent with 2 of the third square root
12x³y² $\sqrt{xy}$
this means that the correct answer to your question is 12x³y² $\sqrt{xy}$ .

What is the width of a rectangle with an area of 5/8 inches and the length of 10 inches?

Nimfa-mama [501]

A = LW......W = A/L
A = 5/8
L = 10

W = (5/8) / 10
W = 5/8 * 1/10
W = 5/80 = 1/16
