Answer:
16.25, 20, 13.75, 12.5, 7.5
Step-by-step explanation:
1cm= 2.5m
6.5x2.5= 16.25
8x2.5= 20
5.5x2.5= 13.75
5x2.5= 12.5
3x2.5= 7.5
How do you solve
5x2 - 13x = 6
Using the ax2 +bx + c = 0 equation
I personally like the square method but I am lazy to draw this out (take too long)
5x²-13x-6 = (5x+2)(x-3)
x = -2/5 or 3
Double-check:
5x²-15x+2x-6 = 5x²-13x-6 √

on weekends a movie ticket costs $10.50. form an inequality and solve it to find the maximum number of tickets kate can buy with $205
STEP BY STEP EXPLANATION PLEASE
$10.50
10 Tickets would be $105.00
$105.00 - $10.50 = $94.50 so 9 Tickets would be $94.50
$105.00 + $94.50 = $199.50
$205.00 - $199.50 = $5.50 which isn't enough for another ticket.
10 Tickets + 9 Tickets = 19 Tickets.

Drake bought a $110,000 life insurance policy at $12.95 for a 20 year term.
What will he pay over 20 years for the premium?
Drake will pay $28,490 over 20 years for the premium.
Data and Calculations:
Life insurance policy = $110,000
Insurance term = 20 years
Premium rate = $12.95 per $1,000
Total premium per year = $1,424.50 ($12.95 x $110,000/$1,000)
Total premium for 20 years = $28,490 ($12.95 x $110,000/$1,000 x 20)
Thus, Drake will pay a total premium of $28,490 for 20 years.

What are the solutions of y=x^2+5x-7
Answer:
You have two variables, and only one condition. It means you have infinite solutions of the form [tex](t; t^2+5t-7)[/tex]. Technically correct, probably not what you want to know.
If you wanted to know if and where the RHS crosses the x axis, the points are the solution to
[tex]x^2+5x-7= 0 \rightarrow x=\frac12(-5\pm\sqrt{25+28})\\x_1= \frac12(\sqrt{53}-5); x_2=-\frac12(\sqrt{53}+5)[/tex]
If you wanted the graph it's a parabola passing through the two points we just found, (0;-7), and with an axis of equation [tex]x=-\frac52[/tex].

√8x^3y^2
Answer:
[tex]2xy\sqrt{2x}[/tex]
Step-by-step explanation:
Because this is a whole term in itself (no addition or subtraction), you can just directly find squares and factor them out. First, when looking at 8, you can factor out 4, to get 2 on the outside. Then, while looking at x cubed, you can factor out x squared, to get x on the outside, and when looking at y squared, you can just pull that outside itself, to get y. Now, we have one 2 and one x remaining, for a total of [tex]2xy\sqrt{2x}[/tex]

Sale price = original price - rate of discount is the formula we used if original price and rate of discount are given. True or False, provide some explanation
Answer:
I say true
Step-by-step explanation:
How to calculate discount and sale price:
Find the original price (for example $90 )
Get the discount percentage (for example 20% )
Calculate the savings: 20% of $90 = $18.
Subtract the savings from the original price to get the sale price: $90 - $18 = $72.
And You're all set!
Answer:
False
Step-by-step explanation:
Sale price = original price - rate of discount * original price
Rate of discount is a percent so we need to multiply by the original price to get a a price so that all the units are the same.

25 = 25...............true, these numbers form a right triangle
Given the complementary angle of y is 43º. Find the supplementary angle of y
Step-by-step explanation:
complementary = adds up to 90 degrees.
supplementary = adds up to 180 degrees.
the complementary angle of y is 43 degrees.
so, y = 90 - 43 = 47 degrees.
the supplementary angle of y = 47 is
180 - 47 = 133 degrees
Hello!
Given the complementary angle of y is 43º.
90 - 43 => 47°
Find the supplementary angle of y
180-43 => 137°

does the point (5 6) satisfy the equation y = 2x - 7
Answer: No
Step-by-step explanation: To determine this, all we have to is plug our ordered pair into the equation for x and y.
Remeber that the first number is our x-coordinate and our second
number is our y-coordinate so we plug a 5 in for x and a 6 in for y.
So we have (6) = 2(5) + 7 or 6 = 10 + 7 or 6 = 17.
Since this is not a true statement, this point doesn’t satisfy the equation.
Find the coordinates of the other endpoint when you are given the midpoint (point M) and one of the endpoints (point P).
P = (10, 6) and M = (-4, 8)
Answer:
(-18, 10)
Step-by-step explanation:
If the other end point is Q, the midpoint is ...
M = (P +Q)/2
2M = P +Q
Q = 2M -P = 2(-4, 8) -(10, 6) = (-8-10, 16-6)
Q = (-18, 10)
The other end point is (-18, 10).

45. m∠5 = 180 - 65 =115
46. m∠1 = 180 - 50 = 130
47. m∠4 = 180 - (50+65) = 180 - 115 = 65
