The y - intercept is the graph corresponds to the rate at which Mia spends the quarters.
And, The value of slope will be 2.
What is Equation of line?The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
She spends them at a rate of two every minute until she runs out.
Now,
Since, She spends them at a rate of two every minute until she runs out.
And, The number of quarters Mia has is graphed over time.
We know that;
Usually we represent the independent variable (time) by x and dependent variable (quarters) by y.
Hence, The y - intercept is the graph corresponds to the rate at which Mia spends the quarters.
So, The slope = 2/1
= 2
Thus, The y - intercept is the graph corresponds to the rate at which Mia spends the quarters. And, The value of slope will be 2.

The correct answer is 935,087,000,000,000.
Step-by-step explanation:
Find the value of c that makes x2 + 6x + c a perfect square. Then write the trinomial as a perfect square.
Hi there!
[tex]\large\boxed{c = 9, (x +3)^2}[/tex]
To find the value of c, we can say:
ax² + bx + c
(b/2)² = c
Therefore:
(6/2)² = 3² = 9
Rewrite the trinomial:
x² + 6x + 9
To write as a binomial, take the square root of c:
√9 = 3
Thus:
(x + 3)² = x² + 6x + 9

Answer:
|x − 8| = 6Step-by-step explanation:
|x − b| = c1. x - b = c ⇒ x = b + c2. x - b = -c ⇒ x = b - cWe have solution:

What is the intersection (x, y) of the two lines generated by the 2 equations:
y= x+3
y=-x +7
Answer:
x=2
y=5
Step-by-step explanation:
y= x+3...(1)
y= -x+7...(2)
(1) + (2):
y+y= (x+3) + (-x+7)
2y= (x-x) + (3+7)
2y= 10
y= 5
By substituting y=5 into (1),
we have
5= x+3
x+3=5
x= 5-3
x= 2

(22+(-6/20)) * (214-10(-6/20)) - (284.75)=4424.15
Thank you so much, I just... I cannot will myself to figure out this problem today. Love youuu!
Step-by-step explanation:
(22 + (-6/20) × (214 - 10 ( -6/20)) - (284.75)
(22 - 6/20) × (214 + 60/20) - (284.75)
(22 - 0.3) × (214 + 3) - (284.75)
(21.7 × 217) - 284.75
4708.9 - 284.75
= 4424.15
Sarah needs a PVC pipe with a diameter of 10 inches and a heigh of 2 inches, how much
material is needed to make 5 pipes?
Answer:
314.2in^2
Step-by-step explanation:
GIven data
diameter= 10in
radius= 5in
Height= 2in
The expression for the curved surface area (CSA) of a cylinder is given as
CSA=2πrh
CSA=2*3.142*5*2
CSA=62.84 in^2
The material needed to make one pipe is 62.84in^2
Hence the material need for 5 pipes is
=62.84*5
=314.2in^2
Manuel borrowed $1,500 from his bank and signed a
contract to make monthly payments for two years at 4%
interest compounded annually. How much total interest
will Manuel pay on this loan?
Answer:
The total interest to pay back on the loan is $122.40
Step-by-step explanation:
Here. we want to get the amount of interest on the loan
We are going to use the compound interest formula here
A = P(1 + r/n)^nt
where A is the amount to be paid back
P is the amount borrowed called the principal which is $1,500
r is the interest rate which is 4% annually
This is same as 4/100 = 0.04
n is the number of times the interest will be compounded per year ; annually means yearly and so for this case, n = 1
t is the number of years = 2
So we have;
A = 1500(1 + 0.04/1)^(2)(1)
A = 1500(1.04)^(2)
A =$ 1,622.40
So the amount of interest is the difference between the amount borrowed and the value to pay back
That will be;
$1,622.40 - $1,500
= $122.40

Given:
In triangle [tex]ABC,m\angle A=138^\circ,c=19,a=29[/tex].
To find:
The [tex]m\angle C[/tex].
Solution:
According to the law of sines:
[tex]\dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}[/tex]
Taking [tex]\dfrac{\sin A}{a}=\dfrac{\sin C}{c}[/tex], we get
[tex]\dfrac{\sin 138^\circ}{29}=\dfrac{\sin C}{19}[/tex]
[tex]\dfrac{0.66913}{29}\times 19=\sin C[/tex]
[tex]0.4383959=\sin C[/tex]
Taking sin inverse on both sides, we get
[tex]\sin{-1}0.4383959=C[/tex]
[tex]26.001577^\circ=C[/tex]
[tex]C\approx 26^\circ[/tex]
Therefore, the correct option is b.

Please Help! A bag contains four green marbles and five yellow marbles. You randomly select three marbles. What is the probability that all three marbles are green when (a) you replace each marble before selecting the next marble, and (b) you do not replace each marble before selecting the next marble? Write each probability as a decimal rounded to the nearest thousandth. Then compare the probabilities.
Answer:
A. 0.088
B. 0.048
C. 1.83 times
Step-by-step explanation:
From the question given above, the following data were obtained:
Green (G) = 4
Yellow (Y) = 5
Total = 4 + 5 = 9
A. Determination of the probability of selecting three green marbles with replacement.
Green (G) = 4
Yellow (Y) = 5
Total = 9
P(1st G) = 4/9
P(2nd G) = 4/9
P(3rd G) = 4/9
P(all G) = P(1st G) × P(2nd G) × P(3rd G)
P(all G) = 4/9 × 4/9 × 4/9
P(all G) = 64/729
P(all G) = 0.088
B. Determination of the probability of selecting three green marbles without replacement.
Green (G) = 4
Yellow (Y) = 5
Total = 9
P(1st G) = 4/9
P(2nd G) = 3/8
P(3rd G) = 2/7
P(all G) = P(1st G) × P(2nd G) × P(3rd G)
P(all G) = 4/9 × 3/8 × 2/7
P(all G) = 24/504
P(all G) = 0.048
C. Comparing probability of replacement and without replacement.
P(all G with replacement) = A = 0.088
P(all G without replacement) = B = 0.048
A/B = 0.088/0.048
A/B = 1.83
Cross multiply
A = 1.83 × B
Thus,
P(all G with replacement) = 1.83 × P(all G without replacement)
