Answer:

-4

Step-by-step explanation:

1. They are alternate exteriors meaning they are supposed to be the same so you sort the equation like 134+x=130

2. Then you pass 134 both side like ×=130

-134

3. Which will equal :-4

The true statement is The volume of the larger cylinder is 8 times the volume of the smaller cylinder.

The correct option is (C)

The volume of cylinder is, V=  πr²h.

Volume of large cylinder,

= πr²h

= πd²(2h)

= 2hπd²

Volume of large cylinder,

= πr²h

= π(d/2)²(h)

= πd²h/4

= 2πd²h/8

Hence, The volume of the larger cylinder is 8 times the volume of the smaller cylinder.

Answer:

Step-by-step explanation:

The circumcenter is the intersection of the perpendicular bisectors.

Find the two equations for the perpendicular bisectors and solve the system for intersection point.

Given the vertices A(-4,6), B(6,6), C(6,2)

Find the slope and midpoint of AB and BC

M(AB) is

Perpendicular bisector is a vertical line that passes through (1, 6) so its equation is:

m(BC) is undefined as x-coordinates are same, so the segment is vertical

M(BC) is

Perpendicular bisector is a horizontal line that passes through (6, 4) so it is:

The intersection of the lines x = 1 and y = 4 is the point (1, 4)

The circumcenter is point (1, 4)

Answer:

the length is 33 feet

Step-by-step explanation:

The computation of the length is shown below:

Let us assume the length be x

So the width be 1 by 3 x

And the area is 363 square feet

So

As we know that

Area = length × width

363 = x × 1 ÷ 3 x

363 = 1 ÷ 3x^2

Now

363 × 3 = x^2

1089 = x^2

x = 33 feet

hence, the length is 33 feet

Answer:

26

Step-by-step explanation:

Devaughn = 2x

Sydney = x

x + 2x = 78

3x = 78

x = 78 / 3

x = 26

Hope that helps!

Answer:

26

Step-by-step explanation:

Lets say Devaughn age = d and Sydney age = s

Therefore,

d = 2s

and s + d = 78

Well, we can use substitution for d.

s + (2s) = 78

3s = 78

s = 26

Answer:

simplified its 5:4 for juniors to freshmen's

Step-by-step explanation:

Answer:

5 : 4

Step-by-step explanation:

Ratio of juniors to freshmen = 15 : 12

15 = 3 * 5

12 = 3 * 4

GCF = 3

15 : 12 = 15÷3 : 12÷ 3

         = 5 : 4

The formula for the area of a circle is [tex]\pi r^2[/tex]

So if we have the first one...[tex]3.14*5^{2}[/tex]≈78.5

Now you can solve the other ones with this formula! Good luck!

Step-by-step explanation:

Finding the lengths of a Triangle is [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]

Your triangle is [tex]7^{2}[/tex] + [tex]b^{2}[/tex] = [tex]25^{2}[/tex]

Which is 49 + b = 625

Subtract the difference 625 - 49. then you get the following

b = 576

Finally find the square root of this number and that's your answer: 24

The error interval for d is from 391.6 to 391.9 and 392.1 to 392.4.

We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.

To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.

Given, The depth 'd' of a lake is 392 m, rounded to the nearest integer.

Now a number rounded to the nearest integer to 392 is only possible when the number is less than 392.5 which is 392.4 and greater than 391.5.
