The perimeter of a quadrilateral is 336.
The ratio of the sides is 2: 3: 2: 5. Find
the side lengths.
Just trying to win the CONTEST BUT GOOOOD LUCK
Answer:
56 units, 84 units, 56 units, 140 units
Step-by-step explanation:
Since you have the ratios, you can multiply each by x, because you do not know the actual values.
2x+3x+2x+5x=336
12x=336
÷12 ÷12
x=28
Then, plug in the values of x.
So 2*28= 56
3*28=84
2*28=56
5*28=140
is 14:12 equivalent to 7:5
Answer:
Yep,
it is correct!
Answer:
No
Step-by-step explanation:
14:12 is not equivalent to 7:5 because if you divide 14 by 2, you would get 7. If you divide 12 by 2, however, you will get 6. So the equivalent ratio for 14:12 is 7:6.

The area of a rectangle is represented by 63x^{3}+9x and the length is represented by 7x^{2}+1 . Find the width of the rectangle in terms of x.
Answer:
Step-by-step explanation:
[tex]7x^{2} +1 = 15x[/tex] and [tex]63x^{2} +9x= 135x[/tex]
so, divide because to solve for area you multiply so the opposite of multiplication is division, Anyway so [tex]135x/15x=9x[/tex]

Complete the statements about the cone.
The height is units.
The radius is units.
The volume is Tot cubic units.
10
6
Answer:
The answers are:
The height is 6
The radius is 8
The volume is 128 π cubic units.
Step-by-step explanation:
The height is shown in the picture. So the first answer is 6.
To find the radius, you use the equation. [tex]\sqrt{slant height^{2}- height^{2} }[/tex] = radius
The slant height 10, and the height is 6. So you plug those into the equation and solve.
[tex]\sqrt{10^{2}-6^{2} }[/tex] =
[tex]\sqrt{100-36}[/tex] =
[tex]\sqrt{64}[/tex] = 8
So the radius is 8.
Now we use the equation [tex]\pi[/tex][tex]r^{2}[/tex] [tex]\frac{h}{3}[/tex] = volume.
[tex]\pi[/tex][tex]8^{2}[/tex] [tex]\frac{6}{3}[/tex] =
[tex]\pi[/tex]64 [tex]\frac{6}{3}[/tex] =
[tex]\pi[/tex] 64(2) = 128 [tex]\pi[/tex] cubic units
I hoped this helped you. I would love brainiest.
The statements about the cone is that,
The height is 6 units, the radius is 8 units and the volume is 128π cubic units.
What is Volume?Volume of a three dimensional shape is the space occupied by the shape.
Given a cone.
We have to find the complete the statements related to the cone.
From the figure,
height of the cone = 6 units
Using the Pythagoras theorem,
Radius of the cone = √(10² - 6²) = 8 units
Volume of the cone = 1/3 π r² h
= 1/3 π × 8² × 6
= 128π cubic units
Hence the height, radius and volume of the cone are 6 units, 8 units and 128π cubic units respectively.

What is the equation of a line when the slope is -1/2 and the y-intercept is 0.
Answer:
y = -1/2x + 0
y = mx+b
Step-by-step explanation:
What is the equation of the line that passes through the point (4, -2) and has a
slope of -22
Answer: the answer is y=-22x+86
here is why:
the slope is -22 which is the m --> y=mx+b the point is (4,-2) the x=4 and y= =2
If we set up the equation:
-2= -22(4)+86
-2= -88+86
-2= -2
