Answer:
4. is x = 9
but I don't know about 5. sorry.
Step-by-step explanation:
5x + 3 = 48
-3. -3
5x = 45
5. 5
x = 9
5(9) + 3 = 48
48 = 48
5y + 1
â 4 + 7x â 20y
Let f(x, y) = 7x + 4 5y + 1 . Then fx(x, y) = ________
(a) What is the measure of RQP? Explain your answer.
(b) What is the value of x? Explain your answer with work.
(c) What is the measure of QRP? Explain your answer with work.
(d) What is the measure of RPQ? Explain your answer with work.
Answer:
(a) 90°
(b) 8.75
(c) 63.75°
(d) 26.25°
Step-by-step explanation:
(a) A radius to a point of tangency is always perpendicular to the tangent line there. Q is the point of tangency of line PQ, so the segment RQ from the center of the circle, R, to that point makes a 90° angle with PQ. Angle RQP is 90°.
(b) The sum of the acute angles of a right triangle is 90°, so ...
(5x +20)° + (3x)° = 90° . . . . . the sum of the acute angles is 90°
8x + 20 = 90 . . . . . . . . . . . . simplify, divide by °
8x = 70 . . . . . . . . . . . . . . . . . subtract 20
70/8 = x = 8.75 . . . . . . . . . . . divide by the coefficient of x
(c) ∠QRP = (5x+20)° = (5·8.75 +20)° = 63.75° . . . . . use the value of x in the expression for the angle measure
(d) ∠RPQ = (3x)° = (3·8.75)° = 26.25° . . . . . use the value of x in the expression for the angle measure

What is the mean
here?
Answer:
590.625
Step-by-step explanation:
Add up all data values to get the sum
Count the number of values in your data set
Divide the sum by the count
Answer:
590.625
Step-by-step explanation:
To find the mean, add up all of the values then divide by the amount of values there are.
The total amount is 16 +16+ 41+ 64+ 1322+ 3230+ 16+ 20 = 4725
There are 8 total values so you divide by 8
590.625
