2 answers:

6 0

Assume that 40 percent of X is 55
This means X (40 / 100) = 55 
0.4 X = 55 
X = 55 / 0.4 
X = 137.5 
55 is 40 percent of 137.5

Simple just do 55/0.40 and that gets you 137.5
so 40% of 137.5=55 here is the proof 137.5x0.40=55

Answer is 137.5

X = slide height
sine (35) = opp / hypotenuse
sine (35) = x / 4.1

x = 0.57358 * 4.1
x = 2.351678 meters
Okay to the nearest meter it is 2

A new pair of shoes is advertised for $110. The sales tax is 7.5%. What is the total cost of the shoes?

CaHeK987 [17]

Answer:

$118.25

Step-by-step explanation:

Always convert the percentage to a decimal by moving the decimal two points to the right/dividing by 100. So 7.5 % = 0.075

110 x 0.075 = 8.25 (the amount of tax added)

110 + 8.25 = 118.25

You can also multiply 110 by 1.075, where the "1" is the $110 and the ".075" is the tax, and save the step of adding. 110 x 1.075 = 118.25

Get brainly if right!! Plsss help

ololo11 [35]

Step-by-step explanation:

t8 = a1 + (n - 1)*d

t8 = 17

17 = a1 + 7*d

t12 = 25

25 = a1 + 11d

17 = a1 + 7d Subtract

8 = 4d Divide by 4

8/4 = 4d/4

2 = d

17 = a1 + 7d

17 = a1 + 7*2

17 = a1 + 14 Subtract 14

3 = a1

Sum 20 terms

The 20 term = a1 + 19*2

The 20 term = 3 + 38

= 41

Sum = (a1 + a20) * 20 / 2

Sum = (3 + 41)* 20/2

Sum = 44 * 10

Sum = 440

Find the area of the shaded region.

stiv31 [10]

Hi!

Let's separate this shape into three sections to make it easier to find the area. (see image)

Let's start with the green shape.
The base of the green shape is 20. The height is 6.

20 x 6 = 120

Now the blue shape.
The base of the blue shape is 20, the height is (9 + 6) 15.

20 x 15 = 300

Now the red shape.
The base of the red shape is (20 - 10) 10, the height is 5.

10 x 5 = 50

Add all of the areas together.

120 + 300 + 50 = 470

The answer is 470

Hope this helps! :)

Answer:

B Survey a random sample of eighth-grade students

Step-by-step explanation:

In order to reach the best conclusion without biased data, the best sampling method would be B because not only does it survey 8th graders, but it also surveys a random group, ensuring that not all of the students are potentially excelling in and/or having trouble with homework.
