$\qquad\qquad\huge\underline{{\sf Answer}}$

Let's find the value of given expression for x = 5 ~

$\qquad \sf \dashrightarrow \:3(3x + 5)$

$\qquad \sf \dashrightarrow \:9x + 15$

now, plug in the value of x as 5

$\qquad \sf \dashrightarrow \:9(5) + 15$

$\qquad \sf \dashrightarrow \:45 + 15$

$\qquad \sf \dashrightarrow \:60$

so, the equivalent value is 60

Arc is 41 and angle is 40. I have no other given information but I have to find x

tiny-mole [99]

First of all I want to point out you drew the diagram a little wrong. The Arc is 41 doesn't mean its 41 degrees it means it has length 41 so remove the degrees symbol.

Now for the answer the other arc have to have angle 40 too because vertical angles. And because the radius is the same, both of the length has formula 40/360*pi*2*radius which is 41 in this case. So x has to be 41 also :) Done!

At many golf clubs, a teaching professional provides a free 10-minute lesson to new customers. A golf magazine reports that go

Airida [17]

Answer:

Step-by-step explanation:

a) The objective of the study is test the claim that the average gain in the green fees , lessons or equipment expenditure for participating golf facilities is less than $2,100 under the claim the null and alternative hypothesis are,

H₀ : μ = $2,100

H₀ : μ < $2,100

B) Suppose you selects α = 0.01

The probability that the null hypothesis is rejected when the average gain is $2,100 is 0.01

C) For α = 0.01

specify the rejection region of a large sample test

At the given level of significance 0.01 and the test is left-tailed then rejection level of a large-sample = < - 1.28

V=πr²h
V=(3)(2²)(8)
V=96

V=(πr²h)/3
V=(3)(2²)(3)/3
V=12

V=96+12

a truck that can carry no more than 6400 lb is being used to transport refrigerators and upright pianos. Each refrigerator weigh

Tems11 [23]

I'm not going to do the entire question, but I'll do the first part.

For the first part, you have to set up an inequality. Use context clues, such as no more than (the one used in this sentence) to figure out what the symbol should be for the inequality.
In this case, because it is NO MORE THAN 6400, it would be:

6400 $\leq$ 250r + 475p

where r represents the # refrigerators, and p represents the # pianos

Now that you have the equation, make the graph, then for the 3rd part, plug in 12 and 8 to r and p to see if it keeps the inequality true.

Hope this helps! :)

(-5,7) and (2,5) <br> find the slope of the line passing through the given points

svp [43]

Answer: -2/7

Step-by-step explanation:

To find the slope, you use the formula $m=\frac{y_2-y_1}{x_2-x_1}$ .

$m=\frac{5-7}{2-(-5)} =\frac{-2}{7}=-\frac{2}{7}$

Now, we know the slope is -2/7.
