C doesn’t belong because it has rounded edges. all the other options have vertices

Maybe C because it doesn’t have any straight lines or A because it has all equal faces

The ends of a pipe when measured with a tape measure that has marks every millimeter are exactly at the 0 mark and the 15 meter

exis [7]

If the ends span from the 0 to the 15 meter mark, then the length of the pipe is 15 meters. However, you should report it using the right amount of significant figures. It is mentioned in the problem that millimeter marks are calibrated between meters. Since millimeter is 1/1000 of a meter, you should add three decimal places to the 15 meters. Hence, you should report it as 15.000 meters.

What is the answer to m

tigry1 [53]

Answer:

Height of a cell tower is, 30 m

Step-by-step explanation:

Proportion states that the two fractions or ratios are equal.

As per the given statement:

Let height of a cell tower be h.

Height of a pole = 3m ,

Shadow of a pole = 4 m and

shadow of a cell tower = 36+4 = 40 m

By definition of proportion;

$\frac{\text{Height of a cell tower}}{\text{Shadow of a cell tower}} = \frac{\text{Height of a pole}}{\text{Shadow of a pole}}$

Substitute the given values we get;

$\frac{h}{40}=\frac{3}{4}$

by cross multiply we get;

$4h = 120$

Divide both sides by 4 we get;

h = 30 m

Therefore, the height of a cell tower is, 30 m

Isabel wrote this mystery problem. The quotient is multiple of 6. The dividend is multiple of 9. The divisor is a factor of 12.

Marina86 [1]

Answer:

Consider the expression $q=\frac{a}{b}$ . q is called the quotient, a is is the dividend and b is the divisor.

Since q is a multiple of 6, then q has the form $q=6k$ for some integer k.

Since a is a multiple of 9, then a has the form $a=9s$ for some integer s.

Since b is a factor of 12, then if 12 can be expressed of the form $12=c*b$ , for c an integer. Then b has the form $b=\frac{12}{m}$

Replacing the preview expression in the initial expression we obtain:

$6k=\frac{9s}{\frac{12}{m}}=\frac{9sm}{12}\\6*12k=9sm\\72k=9sm\\72k-9sm=0$

Then $72k-9sm=0,\; for \; k,s,m\in \mathbb{Z}$ is a equation to Isabel's problem.

Please help, basic algebra. Find the value of x

Naily [24]

Answer:

<em>76 degrees</em>

Step-by-step explanation:

The corresponding angles help you solve this.

The vertical angle of x (meaning the one practically in front of it) is 76 degrees, since x is vertical to 76, the degree will be the same.

Find the missing side of the triangle. leave your answer in simplest radical form

KIM [24]

missing side is $x} = 10.15$ mi .

<u>Step-by-step explanation:</u>

Here we have the following info from the figure: A right angled triangle with following dimensions

$Perpendicular = x$

$base = \sqrt{122}$

$Hypotenuse = 15$

By Pythagoras Theorem :

$Hypotenuse^2 = Perpendicular^2 + base^2$

⇒ $Hypotenuse^2 = Perpendicular^2 + base^2$

⇒ $15^2 = x^2 + (\sqrt{122})^2$

⇒ $225 = x^2 + 122$

⇒ $x^2 = 225-122$

⇒ $x^2 = 103$

⇒ $(x^2)^\frac{1}{2} = (103)^\frac{1}{2}$

⇒ $x} = (103)^\frac{1}{2}$

⇒ $x} = 10.15$

Therefore, missing side is $x} = 10.15$ mi .
