Answer:

$1129.93

Step-by-step explanation:

100 - 9.5 = 90.5

8000 - 90.5 = 7909.5

7909.5 ÷ 7 = 1129.93

i hope this helps

Answer:

12

Step-by-step explanation:

Add 3 to 4, you get 7. Divide 21 by 7. Multiply by 4.

Step-by-step explanation:

103° + 37° + < C = 180° { being sum of angles of triangle }

< C = 180° - 140°

< C = 40°

Hope it will help :)

Answer:

k = 13.5

Step-by-step explanation:

Since 3 * 3 = 9

And 3 * 4 = 12

Then 3* 4.5 = 13.5

As the statement goes, "Triangle XYZ is similar to Triangle ABC."

Answer: Choice D

They should be blocked by pain resistance so the subjects are as similar as possible.

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

Explanation:

The process of blocking in statistics is where we group up people in blocks, and each block is determined by a characteristic of some sort. In this case, we're grouping people up by pain resistance level. Those very resistant to pain will be in one group, while those who easily feel pain will be in another block, and so on. It might be effective to have a pain scale and sort people by that.

Blocking is done so that we eliminate unwanted variability. We are testing the effectiveness of the itching cream, so all we care about is if the itch reduces or not. We aren't worried about the levels of pain. However, it says that "Previous studies have shown the effects of treatment may vary based on a subject's pain resistance". So we group up the people by pain tolerance to help eliminate the variability of pain tolerance levels.

This is why choice D is the final answer.

-------------

Extra info:

Answer:D

Step-by-step explanation:

This is due to the question explicitly stating how the previous studies have shown the effects of treatment may vary based on a subjects pain resistance. This leads to the only option that relates to the study's background, D

false, true . false

Step-by-step explanation:

if u want an explanantion you can ask me :)

Answer: a. True b. True c. False

Explanation:

a. 65+25 =90 complementary angles add up to 90°

b. 65 + b + 25 = 180

90 + b = 180

b = 180 - 90

b = 90

Check-

65 + 25 + 90 = 180

90 + 90 = 180

180 = 180 ✅

c.not vertical angles because they aren’t across from eachother

Answer:

(x+4)^2+(y-3)^2 = 85

Step-by-step explanation:

The standard form of equation of a circle is expressed as;

(x-a)^2 + (y-b)^2 = r^2

(a, b) is the center

r iis the radius

Get the radius

Radius is the distance between the two points

r^2 = (-3-3)^2 + (3-(-4))^2

r^2 - (-6)^2+(7)^2

r^2 = 36+49

r^2 = 85

Substitute (-4, 3) and r^2 = 85 into the formula

(x-(-4))^2 + (y-3)^2 = 85

(x+4)^2+(y-3)^2 = 85

This gives the required equation

Answer:

nth term = 0.8 * -5^(n - 1)

First five terms are: 0.8, -4,

20, -100, 500

Step-by-step explanation:

First term, a1 = 0.8

Common ratio, r = -5

a1 = 0.8

Second term = ar

= 0.8 * -5

= -4

Third term = ar²

= 0.8 * -5²

= 0.8 * 25

= 20

Fourth term = ar³

= 0.8 * -5³

= 0.8 * -125

= -100

Fifth term = ar⁴

= 0.8 * -5⁴

= 0.8 * 625

= 500

First five terms are: 0.8, -4,

20, -100, 500

nth term = ar^(n - 1)

= 0.8 * -5^(n - 1)

nth term = 0.8 * -5^(n - 1)

Answer:

97 degrees

Step-by-step explanation:

360 degrees is our total. so:

306 - 60 - 30 - 72 - 46 - 55 = x

x = 97

Answer:

x<24

*the answer will be incorrect if you meant 2/(3x) instead of (2/3)x

Step-by-step explanation:

First, add 7 to both sides of the inequality to get "2/3x<16." Then multiply both sides by 3 to get "2x<48." Finally, divide both sides by 2 to get "x<24"

Answer and Step-by-step explanation:

So, you would do 100 times 31.8, which is 3180, that'll be the area of the rectangle.

Now, the semicircles. They together form a circle.

So, we do pi times d (diameter), which is 3.14 times 31.8 = 99.852

Now we add them together.

99.852 + 3180 = 3279.85 (rounded to the nearest hundredth of a meter)

The rectangle area is 3180.

The Semi circles' combined area is 99.85.

The total area of the figure is 3279.85.

I hope this helps! Have a great day!

Answer:

Step-by-step explanation:

according to the question

the area of full shape

=[tex]\text{area of the rectangle+the area of the full circle}[/tex]

=(100×31.8)+(π×(31.8/2)²)

=3180+(3.14×(15.9)²

=3180+(3.14×252.81)

=3180+793.8234

=3973.8234

=3973.82
