Can Someone Pls Help Me To Solve 15 And 16 And Answer 17 I Will Mark You The Brainly Pls I Will Really

Answers

Answer 1

Answer:

15) x = 20

16) y = 45°, z = 30°

17) all 4 corners = 90°, all 4 sides are equal length, diagonals are perpendicular, diagonals bisect the corner angles.

We can't do the extra credit because we do not have a relationship about the side lengths. We just have angle information.

Step-by-step explanation:

15) 2x + 8 = 3x - 12

x = 20

16) 2y = 90°

y = 45°

3z = 90°

z = 30°

Select an equation that is equivalent to a^2-144b^2 a) (a-12b)^2 B) (a+12b)^2 C) (a-12b)(a+12b) C) a^2-24ab+144b^2

Answers

Answer:

C) (a-12b)(a+12b)

Step-by-step explanation:

a^2-144b^2 = (a-12b)(a+12b)

This is the formula that when two terms squared are written with a minus sign between them their factors are the product of the original numbers once with a plus sign and once with the minus sign.

This can be explained by multiplying them.

                (a-12b)

                *(a+12b)        

                  a²- 12ab

                      +12ab - 144b²      

                    a²    +0    - 144b²    

We see we get the same answer as applying the formula above.

Decrease 117 kg in the ratio 10:13​

Answers

Answer:

90kg

Step-by-step explanation:

it is so because, to decrease a number by a ratio you have to multiply with the smallest number and divide with the biggest one. For example 117 in the ratio 7:3. 117×3=351 which is divided by 7 and is equal to 50.14.

The value 117kg decreased in the ratio 10:13 will be 90kg

Ratios and proportion

Given the ratio 10:13. To reduce 117kg in this ratio, we will follow the steps:

Step 1: Multiply 117 by the smallest value

117 * 10 = 1170

Step 2: Divide the result by the largest value to have:

Value = 1170/13

Value = 90kg

Hence the value 117kg decreased in the ratio 10:13 will be 90kg

A survey of 5,913 American adults concludes that 53% of them prefer Captain America to Ironman. Find the Margin of Error. Type your answer as a Percentage rounded to 1 decimal.

Answers

Answer:

1.3%

Step-by-step explanation:

Phat = 0.53

1 - phat = 1 - 0.53 = 0.47

Sample size, n = 5913

Assume the confidence level = 95%

Zcritical at 95% = 1.96

Margin of Error = Zcritical * √(phat(1 -phat)) / n

Margin of error :

1.96 * √((0.53 * 0.47) / 5913)

1.96 * 0.0064905

= 0.0127215

= 0.0127215 * 100%

= 1.272%

= 1.3%

I think the blocks are a unit each and you have to count how much space the triangle is taking up

Answer:

Step-by-step explanation:

Remark

This is one of those things that when you see it, you think that really is something.

The trick is to subtract a smaller right triangle from a larger one.

The base for both triangles is 4 (going from where the right angle is to your right where the lines of the red enclosure meet.

Calculations

The height of the larger triangle is 8

The height of the smaller triangle is 5

Area_L = 1/2 8 * 4 = 1/2 * 32 = 16

Area_S = 1/2 5 * 4 = 1/2 * 20 = 10

Red area = 1/2 * 32 - 1/2*20 = 16 - 10 = 6 units
