ln triangle PQR, angle P-Q=20 and angle Q-R=50, find the value of angle R
Answer:
R = 20Step-by-step explanation:
The sum of measures of angles in triangle is always 180°:
P + Q + R = 180
Q - R = 50 ⇒ Q = 50 + R
P - Q = 20 ⇒ P = 20 + Q = 20 + 50 + R = 70 + R
so:
P + Q + R = 180
70 + R + 50 + R + R = 180
120 + 3R = 180
3R = 180 - 120
3R = 60
R = 60:3
R = 20

HELP ME PLZ Between 9 P.M. and 6:20 A.M., the water level in a swimming pool decreased by 7/12 . Assuming that the water level decreased at a constant rate, how much did the water level drop each hour? The water level decreased by nothing in. each hour.
Answer:
0.06245
Step-by-step explanation:
Decrease 7/12=0.583
from 9 p.m to 6:20 am is 9:20= (9+20/60) = 9.33 hours
0.583/9.33 = 0.06248
round the 0.06248 to 0.06245

Let g(x) = 3x² – 1. Find g(-2).
c.
a. (-2, 11)
b. (-2, -7)
(-2, -13)
d. (-2,5)
Answer:
g(- 2) = 11
Step-by-step explanation:
To evaluate g(- 2) substitute x = - 2 into g(x) , that is
g(- 2) = 3(- 2)² - 1 = 3(4) - 1 = 12 - 1 = 11
x = - 6, y = - 3 and z = 4 Evaluate the following expression when x ^ 2 * y - 4z

Can 702 be written as the product of two prime numbers?
Answer:
Since the sum of its digits equals nine, 702 is divisible by nine.
702 is a composite number.
Prime factorization: 702 = 2 x 3 x 3 x 3 x 13, which can be written 702 = 2 x (3^3) x 13
The exponents in the prime factorization are 1, 3, and 1. Adding one to each and multiplying we get (1 + 1)(3 + 1)(1 + 1) = 2 x 4 x 2 = 16. Therefore 702 has exactly 16 factors.
Factors of 702: 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
Factor pairs: 702 = 1 x 702, 2 x 351, 3 x 234, 6 x 117, 9 x 78, 13 x 54, 18 x 39, or 26 x 27
Taking the factor pair with the largest square number factor, we get √702 = (√9)(√78) = 3√78 ≈ 26.49528.

„Ms. Karone orders a total of 350 black, blue, and red pens for the school.
• She orders 170 black pens.
• She orders 120 blue pens.
Which equation can be used to find r, the number of red pens Ms. Karone
orders?
350 - 170 – 120 =r
350 + 170 + 120 =
350 – 170 + 120 = r.
350 +170 – 120 = r
Answer:
350 - 170 – 120 = r
Step-by-step explanation:
Since there is a total of 350 black, blue, and red pens, and we know how many black and blue ones there are, this can be used to find the number of red ones.
350 - 170 – 120 = r can be used to find the number of red pens, because if you subtract the amount of black pens (170) and the amount of blue pens (120) from the total, that will leave you with r, the amount of red pens.
So, 350 - 170 – 120 = r is the correct equation.

Sharon and Tim each opene a savings account on the same day. Sharon started by putting $15 in her account, and she will deposit an additional $7 each week. Tim made an initial deposit of $35, and he will add $3 more each week. Eventually, Sharon and Tim will each have the same amount saved. What is that amount?
Answer:
Step-by-step explanation:
Sharon y = 7x + 15
Tim y = 3x + 35
7x + 15 = 3x + 35
4x + 15 = 35
4x = 20
x = 5 weeks
Sharon: 7(5) + 15 = 35 + 15 = $50
Tim: 3(5) + 35 = 15 + 35 = $50

Is y= -2 a function? Someone please help me ✌️✨
Answer:
no it's not
hope it helps;)
Answer:
No
Step-by-step explanation:
A function is defined as a set of outputs based on a set of inputs.
This means that we need to have two variables in order for this to be a function.
y needs to change as we input different values of x.
However, there are no x values here! It's just a simple line.
Therefore this is not a function.
