take a look at this image, because ac=25 you set dc as x and ad as 25-x, then after that, you can form the equation root of 25^2-(x5-x)^2=root of 30^2-(x)^2 using the pythaeogrem theorem. After that you would get that x=18, then after that you just apply the theorem. 30^2-18^2 root which you would then get 24.

how do I find "Z"? of possible can you do a step by step?
Answers
Answer:
z = 7.5
Step-by-step explanation:
Polygon ABCD and polygon EFGH are similar, therefore, their sides would be proportional to each other. This means the ratio of their corresponding sides would be equal to each other.
BC corresponds to FG
CD corresponds to GH
Therefore:
8/6 = 10/z
4/3 = 10/z
Cross multiply
4*z = 10*3
4z = 30
4z/4 = 30/4
z = 7.5

-3,6,-28,72,-360,2160, ___ ,___
Answers
Answer:
Step-by-step explanation:
a₁ = -3 = (-1)¹×3
a₂ = 6 = (-1)²×2×3
a₃ = -28 = (-1)³×2²×7
a₄ = 72 = (-1)⁴×2³×3²
a₅ = -360 = (-1)⁵×2³×3²×5
a₆ = 2160 = (-1)⁶×2⁴×3³×5
That's as far as I got. I can predict that a₇ is a multiple of -32 and a₈ is a multiple of 64, but I don't see the pattern with the other factors.
The local diner employs three servers, Ally, Benny, and Charli. On Monday night Ally served 40% of the customers, while Benny served 27%. What percent did Charli serve?
That night 60% of Ally's customers ordered pie, while 40% did not. Of Benny's customers, 20% ordered pie. What percent did not?
Find the probability that a customer ordered pie on Monday night.
Given that a customer ordered pie that night, what is the probability that their server was Ally? Round to the nearest whole percent.
Answers
Answer: See explanation
Step-by-step explanation:
Ally served 40% of the customers
Benny served 27%
Percentage served by Charli will be:
= 100% - (40% + 27%)
= 100% - 67%
= 33%
That night 60% of Ally's customers ordered pie, while 40% did not. Of Benny's customers, 20% ordered pie.
The percent that did not will be:
= 100% - 20%
= 80%

Both x and y because it’s a 45-45-90 triangle
Answer:
x = 6√(2)x = 6√(2)y = 6√(2)Step-by-step explanation:
Sides equal opposite to equal angles are always equal -----------<1>If one angle of triangle is 90°, then it is a right triangle, can find sides with the help of Pythagoras Theorem. -----------<2>The sum of all three sides of any triangle is 180°. -----------<3>→ Given angles of triangle = 45° + 45° + 90° {from <3>}
→ x = y {because of <1>}
→ H² = P² + B² (Pythagoras Theorem) {from <2>}
→ (12)² = x² + y²
→ 144 = x² + x² [x = y]
→ 144 = 2x²
→ 144/2 = x²
→ 72 = x²
→ √(72) = x
→ 6√2 = x
→ x = y
so,
x = 6√2 = y
x = 6√(2)y = 6√(2)HOPE THIS HELPS YOU

A department of transportation's study on driving speed and miles per gallon for midsize automobiles resulted in the following data. Speed (Miles per Hour) 30 50 40 55 30 25 60 25 50 55 Miles per Gallon 29 26 26 22 29 31 21 35 25 26 Compute the sample correlation coefficient. (Round your answer to two decimal places.) Interpret the sample correlation coefficient. There is a strong negative relationship between the driving speed and miles per gallon. For driving speed between 25 and 60 miles per hour, higher speeds are associated with lower miles per gallon.
Answers
Answer:

55
Miles per Gallon :

The correlation Coefficient, R shows the degree or level of relationship between the dependent and independent variable. A positive R value denotes a positive correlation while a negative R value denotes a negative relationship. R values should range between - 1 to +1 with values close to 1 and - 1 depicting strength while value of zero means no relationship exist.
Hence, R value of -0.90 depicts a strong negative relationship. Hence, higher speed are related to lower miles per gallon and vice versa.

Jolyn was paid $340 last week working 17 hours. What was Jolyn’s hourly pay? Do not include the units in your answer
Answers
Answer:
20
Step-by-step explanation:
It is mentioned that Jolyn made $340 in 17 hours last week. In order to evaluate this, you'll have to divide the money earned by the hours worked.
[tex]\frac{340}{17} =20[/tex]
Therefore, Jolyn makes $20 an hour as 20 x 17 = 340 which is correct,
An office supply store recently sold a black printer ink cartridge for $14.99 and a color printer ink cartridge for $23.99. At the start of a recent fall semester, a total of 64 of these cartridges was sold for a total of $1157.36. How many of each type were purchased?
Answers
49 were sold in total, hence,
B+C= 49 ------------(1)
Also, its given that
18.99 B + 27.99 C = 1146.51---------(2)
Multiplying (1) by 18.99,
18.99 B+ 18.99 C= 930.51 ------(3)
Now, subtracting (3) from (2),
18.99 B + 27.99 C = 1146.51
18.99 B+ 18.99 C= 930.51
------------------------------------
9 C = 216
C= 24
We know, B+ C= 49
Hence B = 49-24 = 25
Hence, number of Black printer ink cartridges = 25 and color printer ink cartridges = 24.
