do you want an expression?
if so it would be T = 40 + 20h
t = total
h = hour(s)
Answer:
x = 87
Step-by-step explanation:
the ratio SR / RV is equal the ratio ST / TU (both ratios are equal to 1), and the angle in the vertex S is the same for both triangles SUV and STR, so we can affirm that these triangles are similar (case S-A-S).
Then, we have that the ratio SR / SV is the same as RT / UV:
SR / SV = RT / UV = 1 / 2
RT * 2 = UV
2*(x - 37) = x + 13
2x - 74 = x + 13
x = 87
Answer:
y = 2x² - 5x + 7
Step-by-step explanation:
General form of a quadratic is:
y = Ax² + Bx + C
Using the given points, construct equations and solve for A,B and C.
When x = 0, y = 7
7 = A(0)² + B(0) + C
C = 7
y = Ax² + Bx + 7
When x = -1, y = 14
14 = A(-1)² + B(-1) + 7
A - B = 7
A = 7 + B
When x = 1, y = 4
4 = A(1)² + B(1) + 7
A + B = -3
(7 + B) + B = -3
2B = -10
B = -5
A = 7 + (-5)
A = 2
y = 2x² - 5x + 7
Answer:
225 p/p
Step-by-step explanation:
This design consists of 3 groups of participants, each with 25 members and three case studies, thus:
case (1) 17 inch ----------- 25 members
case (2) 18 inch ----------- 25 members
case (3) 21 inch ----------- 25 members
Total: case = 3 ----------- 75 members
Total pieces of paper = 3*75 = 225 piece of paper
Answer: 9 likes
Step-by-step explanation:
Question is incomplete but assuming the question is to find out the number of likes that Rebecca's video had, it was:
Amina had 63 likes and this is 7 times more than Rebecca's.
Assume Rebecca's are x:
7x = 63
x = 63/7
x = 9 likes
