(11x + 8) + (8x + 12) =27
Answer:
11x + 8 +8x +12 =27 (drop the parenthesis, there's no actual need for them)
19x +20 =27 (i combined like terms and then subtracted 20 from both sides)
19x = 7 (divide both sides by 19 to get x alone)

Find the surface area of the 3D solid. Round to one decimal place.
Answer:
172.5
Step-by-step explanation:
The formula for the surface area of a right circular cone (the following shape) is πr( r + √h^2 + r^2). Since the radius (r) is already given (3) and the height (h) is already given (15), you just replace each r with 3 and h with 15. After solving this out, you should get 172.45, which rounds to 172.5 to the first decimal place

simplify the expression a² • 3a and explain your steps pls
Answer:
3a^3
Step-by-step explanation:
Ok I got you bud now the the first thing to notice that they're all the same variable. so the way I learned to look at is like this
1a^2 x 3a^1
so the reason I put it like this is so I remember that in front of every variable is a coefficient. so you would first multiply the coefficient
3x1=3
3
then multiply the a's you have one a that is being squared and one a to the first power so since your multiplying them you just add the exponents
a^1 + a^2 = a^3
so when you put it all together it says 3a^3
hope this helps

Suppose a cylinder has a diameter of 18 feet and a height of h feet. Which equation can be used to find V, the volume of the cylinder in cubic feet?
Answer:
Volume of a cylinder, V = πr^2h
but r= d/2
therefore, Vol = π(d/2)^2h
from the parameters given,
Vol = π(18/2)^2h
=81πh
identify the slope and write the equation of the line .
Answer:
y=-2x+5; slope is -2
Step-by-step explanation:
slope is rise/run. we can see it rises 2 and goes left one which would give us rise/run=2/-1=-2. that is our slope.
using y=mx+b to write the equation, m is slope and b is the y-int.. we can see that the y-int. is (0,5). we can plug 5 into b.
plugging b and m in we can get the equation: y=-2x+5
Find the volume of a pyramid with a square base, where the side length of the base is
14.4 m and the height of the pyramid is 15.3 m. Round your answer to the nearest
tenth of a cubic meter.
Answer:
Volume of pyramid with square base is 1057.54 m³
Step-by-step explanation:
We are given:
Length of base of pyramid = 14.4 m
Height of pyramid = 15.3 m
We need to find:
Volume of pyramid with square base
The formula used is: [tex]Volume=\frac{1}{3}\times a^2 \times h[/tex]
Where a = base of pyramid and h is height
Putting values and finding volume
[tex]Volume=\frac{1}{3}\times a^2 \times h\\Volume=\frac{1}{3}\times (14.4)^2 \times (15.3)\\Volume=\frac{1}{3}\times 207.36 \times 15.3\\Volume=1057.54 \ m^3[/tex]
So, Volume of pyramid with square base is 1057.54 m³

1057.5

-6x-2y=42
x-y=-15
Multiply x-y=-15 by 6 ( eliminate the x first)
6(x-y)=6(-15)
(6)(x)=6x
(6)(-y)=-6y
6(-15)=-90
-6x-2y=42
6x-6y=-90
eliminate x the systems of equations by subtracting
-6x+6x-2y+-6y=42-90
-2y-6y=42-90
-8y=-48
divide both sides by -8 to get y by itself
-8y/-8=-48/8
y=6
Find x by substitution method
use y=6 into one of the system of equations
x-y=-15
x-6=-15
move -6 to the other side
sign changes from -6 to +6
x-6+6=-15+6
x=-15+6

Hana has some blue paint. She wants to lighten the shade, so she mixes in 1
cup of white paint. The color is still too dark, so Hana keeps mixing in 1 cup of
white paint at a time. After adding 4 cups, she decides the color is too light.
Answer:
The answer is below
Step-by-step explanation:
Hana has some blue paint. She wants to lighten the shade, so she mixes in 1 cup of white paint. The color is still too dark, so Hana keeps mixing in 1 cup of white paint at a time. After adding 4 cups, she decides the color is too light.
How would she express the amount of paint to add to be between too dark and too light.
Solution:
After adding a cup of white paint, the color is still dark, she adds the second cup of paint and the color is still dark. She adds the third cup of paint and the color is still dark but when she adds the fourth cup of white paint, the color became too light.
This means that the amount of paint to add to be between too dark and too light is between the third and fourth cup.
Let w represent the amount of paint to add to be between too dark and too light. Hence:
3 < w < 4
A squirrel burrowed 6 holes in 2 minutes. How many holes could the squirrel burrow in 7 minutes
Answer:
He burrows 6 holes in 2 minutes which means that he can burrow 3 holes in 1 minute.
To determine how many he can burrow in 7 minutes, you would multiply the
unit rate of 3 holes in 1 minute by 7.
He would burrow 21 holes in 7 minutes.
Step-by-step explanation:
brainliest pls?
Answer:
He burrows 6 holes in 2 minutes which means that he can burrow 3 holes in 1 minute.
therfore your answer would be 21 holes in 7 minutes

Use the coordinates J(7, 8), K(1, 2) and L(5, 2) for △JKL.
The centroid for △JKL is at point M. What is JM rounded to the nearest tenth?
prolly D
..............................
The distance between the point JM will be 4.81 units.
What is the centroid of the triangle?In science and math, the centroid of a planar figure or firm figure, also known as the point of intersection or center of the figure, is the mean absolute position of all of the other points on the subject's surface.
The centroid of the triangle is given as,
(x, y) = [(x₁ + x₂ + x₃) / 3, (y₁ + y₂ + y₃) / 3]
Use the coordinates J(7, 8), K(1, 2) and L(5, 2) for △JKL. Then the centroid for △JKL is at point M is given as,
(x, y) = [(7 + 1 + 5) / 3, (8 + 2 + 2) / 3]
(x, y) = (13/3, 12/3)
(x, y) = (13/3, 4)
Then the distance between the point JM is calculated as,
D² = (13/3 - 7)² + (4 - 8)²
D² = 7.1111 + 16
D² = 23.11
D = √23.11
D = 4.81 units
The distance between the point JM will be 4.81 units.
More about the centroid of the triangle link is given below.

Step-by-step explanation:
Consecutive angles are equal only when dealing with a square or a rectangle. All other 4 sided figures do not have this property.
So the answer is sometimes.

Answer: m∠T = 48°
ΔMAT has MA = MT
=> ΔMAT is a isosceles triangle at M
=> ∠A = ∠T = (180° - ∠M)/2
=> x + 20 = (180 - 3x)/2
⇔ 2x + 40 = 180 - 3x
⇔ 5x = 140
⇔ x = 140/5
⇔ x = 28
=> ∠A = ∠T = 28 + 20 = 48°
