Answer:
x = -37.5
Step-by-step explanation:
Set up a proportion so -5/12.5 = 15/x
Solve for x so -5x = 15(12.5) so -5x = 187.5 so x = -37.5

The volume of this cylinder is 175pi cubic units. What is the volume of a cone that has the same base area and the same height? Write your answer in terms of pi.
Answer: 58.33π units ³
Step-by-step explanation:
The volume of a cylinder = πr²h
The volume of a cone = 1/3πr²h
Since we have been told that the volume of this cylinder is 175pi cubic units and that the cone has the same base area and the same height, then the volume of the cone will be the volume of the cylinder divided by 3. This will be:
= 175π / 3
= 175/3π
= 58.33π units ³
The volume of the cone is 58.33π units ³
Answer:
183
Step-by-step explanation:
When multiplied by pi, it rounds out to 183.

Justine earned $19,000 during the first year of her job at city hall. After each year, she received a 8.6% raise. Find her total earnings throughout her 20-year career.
Answer:
929,477.13
Step-by-step explanation:
Number of years, n = 20
Using the relation :
a(1- r^n)/ (1 - r) ;
where a is the first term, r is the common ratio and n is the number of years
a = 19000
r = 1 + 8.6% = 1.086
19000(1 - 1. 086^20) / (1 - 1.086)
19000(1 - 1.086^20) / (1 - 1.086)
−79935.0336930 / (1 - 1.086)
= 929,477.13

A regular heptagon has an apothem of approximately 4.2 ft and a perimeter of approximately 28.0 ft.
Find the area of the heptagon.
Answer:
Step-by-step explanation:
If perimeter is 28 then each side is 28/7=4ft These sides can be seen as the bases of seven triangles that make up the heptagon. The apothem, 4.2ft, is the height of each of those triangles. The total area will be the sum of the areas of those seven triangles.
A=7(bh)/2
A=(7(4)4.2)/2
A=58.8 ft^2
Find the midpoint, M, of CD.
C = (2,5) D = (-4,1)
M = ([?],[ ])
Answer:
M= ([-1],[1/2])
The number in the green box is -1
Step-by-step explanation:
M= ([x1+x2/2], [y1+y2/2])
M= ([2+(-4)/2], [5+1/2])
M= ([-2/2, 6/2])
M= ([-1, 3])
Can someone help me on this please? X/4=-12 this says x divided by 2 equals -8. Explain how you would solve for x and what you would get.
Answer:
-48 ; - 16
Step-by-step explanation:
Given the expression :
X /4 = - 12
Multiply both sides by 4
X/4 * 4 = - 12 * 4
X = - 48
For the second :
X/2 = - 8
Multiply both sides by 2
X/2 * 2 = - 8 * 2
X = - 16
please help I’ll give pts and brainiest
Help please like can u explain instead of just giving me the answer
Answer:
Thanks for asking for the explanation, everyone wants just the answer, You want to know how to solve the problem , great. :)
Step-by-step explanation:
Our strategy and one you can use on any triangle problem.
the interior angles add to 180° . Remembering that, seems to me, that very often is the "key" to figuring out triangle problems.
keeping that in mind, we know to add up all the inside angles to 180
180= A + B + C
from this particular triangle then, we have
A = 6X
B = 90 ( b/c that's what the small red square is telling us, it's a 90 angle )
C = 5x - 2
put that all together
180 = 6x + 90 +5x - 2
now use your algebra skills to solve for X ( and to be fair, this is where lots of people struggle, the algebra skills are not so good )
so I'll just go slow
put like terms together
180 = 11x + 88 ( I just added the terms with an x, and the constant terms )
move the 88 over to the other side by subtracting
92 = 11x
divide both sides by 11
92 / 11 = x
8.3636 = x
now that we know x, plug it into the expression for the angle next to the y angle in the picture
5x - 2
5(8.3636) - 2
39.8181
then y is the other part of another 180 pair of angles sooo use that again
180 = 39.8181 + y
solve for y
140.1818 = y
Hope this helps, ask any questions you may have, :)
Se van a repartir 5 barritas de amaranto entre
8 niños, de manera que les toque lo mismo
y que no sobre.
¿Cuánto le tocará a cada uno?
Answer:
De acuerdo a la información proporcionada, dado que se van a repartir 5 barritas entre 8 niños, se tiene que dividir las barritas entre el número de niños y a partir de aquí, se construye la fracción 5/8. Esto lo que indica es que cada barrita se divide en ocho pedazos y cada niño recibiría 1/8 de cada barrita y para las 5 barritas sería:
1/8*5=5/8

Step-by-step explanation:
Laura and martin obtain a 25 year 160,000 conventional mortgage at 10.5% on a house selling for 190,000. Their monthly payment, including principal and interest, is $1510.40
Complete question :
Laura and Martin obtain a 30-year, $180,000 conventional mortgage at 10.0% on a house selling for $210,000. Their monthly mortgage payment, including principal and interest, is $1566.00. Determine the total amount they will pay for their house. How much of the cost will be interest? How much of the first payment on the mortgage is applied to the principal?
Answer:
$563760 ; $383760 ; $66
Step-by-step explanation:
Given that:
Monthly mortgage payment = $1566
Period = 30 years
Number of months in period = (30 * 12) = 360
Principal = $180,000
1.)
Total amount paid :
Monthly payment * period
$1566 * 360 = $563760
2.)
Total amount paid = Principal + Interest
Interest = Total amount paid - principal
Interest = $563760 - $180000
Interest = $383760
3)
First payment = 1566
Interest rate = 10% per annum = 0.1 / 12 = 0.0083333
monthly interest: 180,000 * 0.0083333 = 1500
Principal = 1566 - 1500 = $66
