Answer:

x = 13

∠WZX = 57°

Step-by-step explanation:

Because it is a rectangle, ∠XYZ is 90°

∠XZY + ∠YXZ = 90

(5x - 8) + (x + 20) = 90

simplify:

6x + 12 = 90

subtract 12 from each side

6x = 78

divide both sides by 6

x = 13

∠WZX is complimentary to angle (x + 20)

∠WZX = 90 - (13 + 20) = 57°

The sum of a number times 10 and 17 is at most 27
guajiro [1.7K]

<em>Answer:</em>

<em>The value of the number should be 1 (or less I think)</em>

<em>Step-by-step explanation:</em>

<em>At most means the highest value of the sum should be 27.</em>

<em>10x + 17 = 27</em>

<em>10x = 27 - 17</em>

<em>10x = 10</em>

<em>x = 10/10</em>

<em>x = 1</em>

<em>∴</em><em>The value of the number should be 1</em>

On a standardized exam, the scores are normally distributed with a mean of 145 and a standard deviation of 25. Find the z-score
Kryger [21]

Answer:

z = 2.6

Step-by-step explanation:

<u>Use the formula for z-score</u>

z=\frac{x-\mu}{\sigma}\\ \\z=\frac{210-145}{25}\\ \\z=\frac{65}{25}\\ \\z=2.6

This tells us that this person's score of 210 places them 2.6 standard deviations above the mean

an isosceles triangle contains two equal angles. Each of these angles is 25 degrees larger than twice the smallest angle. What a
Helga [31]
Well, the sum of all internal angles in a triangle, isosceles or whatever else, is always 180°, so the sum of all those three folks, will be 180 then

so.. hmmm let's say the smallest angle is "a" units

twice that is, 2*a, or 2a
25 larger than that? is well 2a + 25

so... the other two twin angles, are 2a+25 each

thus   a + (2a + 25) + (2a + 25) = 180

solve for "a" to find the smalles one

what about the twins? well, each is 2a + 25

Can you please help asap
dybincka [34]
For question 38 it would be C. -38 because -38 - 7 is -45 and -45 divided by 9 is -5.

Question 35 would be B. 4/5 because 80% converted into a decimal is 4/5.

Hope these helped!! :)
