The answer must be 120\quad m{ m }^{ 2 } since the triangular pyramid has 4 faces and each has an area of 30 m{ m }^{ 2 } we should multiply that by 4 , so :

4\cdot 30\quad m{ m }^{ 2 }=\quad 120\quad m{ m }^{ 2 }

In the diagram of circle A, what is the measure of _XYZ?<br> 35 70 75 140
Tasya [4]

Answer:

First Option is correct.

Step-by-step explanation:

Since we have given that

Measure of arc WZ = 175°

Measure of ∠XAZ = 105°

We need to find the measure of ∠XYZ.

As we know the angle subtended at the center is the average of the measure of arc intercepted by it angle and its vertical angles.

Hence, the value of  ∠XYZ is 35°.

Hence, First Option is correct.

An answer is needed ASAP. THANK YOU!

Hey there!

A number that is divisible by both 2 and 9 is 18. This is just 2 multiplied by 9. To make this into a 3-digit number, you can just multiply 18 by itself. This will be 324, which is divisible by 9 and 2. 

324 ÷ 2 = 162

324 ÷ 9 = 36

So, a number you could choose is 324. 

Hope this helped you out! :-)

A line passes through the points (p, a) and (p, –a) where p and a are real numbers. If p=0, what is the y-intercept? Explain your reasoning. 

<span>p - as "x" never changes with the value of "y", so no matter what y is, x is always "p", so when y is 0, x = p </span>

<span>slope of the line </span>
<span>change in y over the change in x </span>
<span>(-a - a) / (p - p) = infinity - or a vertical line </span>
<span>equation of the line </span>
<span>y = p </span>
<span>slope of a line perpendicular to the given line </span>
<span>inverse of the orig slope or (p - p)/(-a - a) = 0</span>
