Each angle = 60 o Explanation: The two alternate interior angles provided are: ( 2 x + 10 ) o and, ( 3 x − 15 ) o A pair of alternate interior angles as per property ,have equal values. ( 2 x + 10 ) o = ( 3 x − 15 ) o ( 10 + 15 ) o = 3 x − 2 x 25 o = x So, angle 1: ( 2 x + 10 ) o = 2 × 25 + 10 = 60 o angle 2: ( 3 x − 15 ) o = 3 × 25 − 15 = 60 o

PLEASE HELP IM NOT GOOD AT MATH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Jimmy was walking to get the mail; at which time he fell into a hole and broke his ankle. He has a PPO insurance plan. His total bill was $2,000. If Jimmy has a $1,000 deductible with an 80/20% co-insurance, how much total will Jimmy have to pay out of pocket? Show your work.
Answer: $200
Step-by-step explanation:
Since there is a deductible here, you deduct it from the total bill first:
= 2,000 - 1,000
= $1,000
With an 80/20% coinsurance plan, you will pay for 20% of this bill and your insurance company will pay 80%.
You will therefore pay:
= 1,000 * 20%
= $200

Find the solution between - x - 3y = 6 and the equation of the line shown on the graph below.
Answer:
They are the same line.
Step-by-step explanation:
y = -1/3x - 2
-x - 3y = 6
First, we need both lines to follow the equation of y = mx + b so that we can graph them. We already have one equation in that form (the one from the graph given), so we can ignore that for now.
Next, we need to solve -x - 3y = 6. Let's first move the x to the other side of the equal sign.
-3y = x + 6
Now, since we have a similar equation to what we need, we just need to divide the y by the given number in front (or -3). But that also means that we must divide the other side by the same amount (or each variable).
-3y = x + 6. -> y = -1/3x - 2
So, your final equation for -x - 3y = 6 should be;
y = -1/3x -2
Bringing down the other equation, we get:
y = -1/3x - 2 and y = -1/3x - 2
Making both equal to each other (they cancel each other out).
Hope this helps!

A bridge spans a distance of 1012m. Large cables are attached to the tops of the towers, 45 m above the road. The road is suspended from the large cables by many smaller vertical cables. The smallest vertical cable measures about 1.5m. Determine a quadratic equation for the large cables.
Answer:
A quadratic equation for the large cables is [tex]f(x) = \dfrac{87 }{512072} \cdot x^2 + 1.5[/tex]
Step-by-step explanation:
The shape of the quadratic equation representing the large cables is a parabola
Taking the point of the smallest vertical cables as the vertex, (h, k) with coordinates, (0, 1.5), we have;
h = -b/(2·a)
∴ 0 = -b/(2·a), from which we have, b = 2·a × 0 = 0
k = 1.5 = c - (b²/(4·a) = c - (0/(4·a)) = c
∴ c = 1.5
The standard form of the quadratic equation, a·(x - h)² + k is therefore, given as follows;
f(x) = a·(x - 0)² + 1.5 = a·x² + 1.5
At the towers which are on either side of the bridge, when x = 1012/2 = 506, f(x) = y = 45
Therefore, we have;
45 = a·506² + 1.5
a = (45 - 1.5)/506² = 87/512072 ≈ 1.699 × 10⁻⁴
The quadratic equation for the large cables, f(x), can therefore be presented as follows;
[tex]f(x) = \dfrac{87 }{512072} \cdot x^2 + 1.5[/tex]

If interest is compounded semi-annually, which expression represents the account balance in t yeats?
Answer:
ANNUAL Compounding : Total = Principal * (1 + rate)^years
Semi-Annual TOTAL = Principal * (1 +rate/n)^n*years
where "n" is the number of compounding periods per year
So the formula for semi-annual compounding is
TOTAL = Principal * (1 +rate/t)^t*years

Casey's drill team squad was responsible for painting props for a performance at a band contest. The squad painted 18 props in 90 minutes. If they continued painting at this rate, how many props would they paint in 3 hours?
Answer: They would paint 36 props in 3 hours.
Step-by-step explanation:
Given: The squad painted 18 props in 90 minutes.
Time taken to paint each prop = [tex]\dfrac{90\text{ minutes}}{18}[/tex]
= 5 minutes
Now, 1 hour = 60 minutes
3 hours = 3 x 60 minute = 180 minutes
Total props painted in 3 hours = (180 )÷5
= 36
Hence, with same rate , they would paint 36 props in 3 hours.

Solving a Real-World Problem
Mr. Martin is giving a math test next period. The test, which is worth 100 points, has 29 problems. Each problem is
worth either 5 points or 2 points. Write a system of equations that can be used to find how many problems of each
point value are on the test.
Let x be the number of questions worth 5 points and let y be the number of questions worth 2 points.
x + y = 29, 5x + 2y = 100
x + y = 100, 5x + 2y = 29
5x + y = 29, 2y + x = 100
2x + y = 100, 5y + x = 29
Answer:
x + y = 29
5x + 2y = 100
Step-by-step explanation:
Here, we want to set up equations
There are 29 problems, so adding up the number of individual problem types will give 29
x + y = 29 ••••••(i)
Let us work with points now;
x is worth 5 points, y is worth 2 points
Thus, mathematically;
5x + 2y = 100 ••••••••••(ii)
Answer: A. x + y = 29, 5x + 2y = 100 and the other one is B. 14 problems worth 5 points and 15 problems worth 2 points

I wasn't in class so I need help solving the inequality 7/10n+14<49
Answer:
n<50
Step-by-step explanation:
7/2*5n + 14<49
7n/2*5+14<49
(7n)+(2*5)14/2*5 <49
7n+10*14/2*5 <49
7n+140/2*5 <49
7n+140/10 <49
7n+140 < 10*49
7n+140 < 490
(7n+140)+(-140)<490+(-140)
7n+140-140<490-140
7n<350
7n/7 < 350/7

Answer:
B. 20 = 2g
Step-by-step explanation:
What we see here is a diagram showing a bar of 20 at the top, and a pair of g's bars each taking up half of the 20 bar.
Seeing this, that would mean the 2 bars showing g equal 20, so the equation 20 = 2g is the one which the diagram shows.
