Can someone pls help me to solve 15 and 16 and answer 17 I will mark you the brainly pls I will really appreciate
Answers
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°

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 proportionGiven 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

I think the blocks are a unit each and you have to count how much space the triangle is taking up
Answer:
6
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

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%
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
