What is an equation of the line that passes through the points (-6,-5) and (-3,0)?put your answer in fully reduced form
Step-by-step explanation:
The equation is y = -3x + 6.
Answer:
3y = 5x + 15
Step-by-step explanation:
Slope = Change in y-cordinates
---------------------------------
Change in x-cordinates
= 0 - (-5)/-3 - (-6)
= 5/3
Using point (-3,0)
y - y1 = m(x - x1)
y - 0 = 5/3 (x - (-3))
y = 5/3 (x + 3)
Expand the bracket
y = 5x/3 + 15/3
Multiply through by 3
3y = 5x + 15

A spherical container has a diameter of 100 centimeters. It is filled with a liquid that costs $80 per cubic centimeter. What is the total value of the liquid in the container?
Use 3.14 for π.
Enter your answer in the box to the nearest penny. will mark brainliest
Answer:
The total value of the liquid in the container is about $41,866,666.67.
Step-by-step explanation:
A spherical container has a diameter of 100 centimeters.
It is filled with a liquid that costs $80 per cubic centimeter.
And we want to determine the total value of the liquid in the container.
We can start by finding the volume of the container.
Since the container has a diameter of 100 centimeters, its radius if 50 centimeters.
The volume of a sphere is given by:
[tex]\displaystyle V=\frac{4}{3}\pi r^3[/tex]
Substitute. We will also use 3.14 for π. So:
[tex]\displaystyle =\frac{4}{3}(3.14)(50)^3=523333.33...\text{ cm}^3[/tex]
(Try not to round intermediate values.)
Since each cubic centimeter costs $80, we will multiply the total volume by the cost per cubic centimeter to find the total value. Thus, the total value is:
[tex](523333.\overline{3})(80)\approx \$41, 866, 666.67[/tex]
The total value of the liquid in the container is about $41,866,666.67.

Answer:
-9
Step-by-step explanation:
(x + 89)° + (x + 109)° = 180°
(interior angles on the same side of transversal)
(2x + 198)° = 180°
2x + 198 = 180
2x = 180 - 198
2x = - 18
x = - 18/2
x = - 9
The measure of angle R is 129 degrees,
What is the measure of angle S?

pls answer asap!!ty!!
Please label the missing angles below.
Answer:
Triangle A: 38 degrees
Triangle B: Unknown (not enough information)
Triangle C: Unknown (not enough information)
Triangle D: 70 degrees
Triangle E: 40 degrees
Step-by-step explanation:
Work for Triangle A: 90 + 52 = 142. 180 - 142 = 38.
Work for Triangle B: Unidentifiable because there is no indicator to tell you if any of the angles/lines are equal. Generally there will be a "double lined" indicator in the corners of which a triangles angles are equal.
Work for Triangle C: Same as B.
Work for Triangle D: 90 + 20 = 110. 180 - 110 = 70.
Work for Triangle E: 90 + 50 = 140. 180 - 140 = 40.

Lara borrowed $4500 for some home repairs. She will be paying 6% in simple interest over the next three years. What is the total amount she will be paying on the loan
Answer:
5310
Step-by-step explanation:
6% of 4500=270
270x3years=810
4500+810=5310
Lara will be paying the total amount is $5310
What is simple interest?Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.
Given that, Lara borrowed $4500 for some home repairs. She will be paying 6% in simple interest over the next three years.
We need to find the total amount she will be paying on the loan,
So, the formula for simple interest is - SI = PRT / 100
P = principal, r = rate and t = time
Therefore,
SI = 4500 x 6 x 3 / 100
= 45 x 18 = 810
The interest = $810
She will pay = interest + principal = 810 + 4500 = $5310
Hence, Lara will be paying the total amount is $5310

114 students chose tea as a drink
19.87 but there’s a 20% discount what’s the answer now?
19.87 = 100%
If you divide both sides by ten, you would get what ten percent is.
1.987 = 10%
Multiply this by two to get 20%.
3.974 = 20%
Minus twenty percent from the original amount.
18.87 minus 3.974 = 15.886 after the discount.

Matteo spends a total of 38 min exercising. He walks for 6 min to warm up and then runs at a constant rate of 8 min per mile for the rest of the time. Matteo says that he ran 4.75 mi. Is he correct?
Answer:
No, he not correct because he only ran 4 mi
Step-by-step explanation:
If he walks for 6 min out of the 38 min, then he ran for 32 min.
d = rt 1 mi = 8r
r = 1/8 = 1 mi/8 min Since he ran 32 min we have
d = 1/8(32) = 4 mi.
No, he not correct because he only ran 4 mi
