You have 2 triangles and 3 rectangles. 
Start with a triangle:
area is base side * height / 2 ->  4 * 3 / 2 = 6
The other triangle has the same area: 6

First rectangle: side * other side -> 7 * 5 = 35
Second rectangle: 7 * 4 = 28
Third rectangle: 7 * 3 = 21

Now simply add all this together: 6+6+35+28+21 = 96

A single die is rolled one time. Find the probability of rolling an odd number or a number less than 3
Sergeeva-Olga [200]
I'm pretty sure it'd be 4/6 and then it'd simplify to 2/3. You add together the possibilities of rolling an odd number (3/6) to the possibilities of getting a number less than 3 (2/6) and then subtract the number that they both had in common (which would've been the number 1). So it'd be 3/6+2/6=5/6 - 1/6. and you'd get 2/3

What is the volume of a square pyramid if the perimeter of the base is 44 in and the height is 19 in.? Round to the nearest tent
allochka39001 [22]

Answer:

2299 in^2

Step-by-step explanation:

The formula for the volume of a square pyramid of base A and height h is

V = (A)(h).

Here, the perimeter of the base is 44 inches, so that the length of one side must be (44 in) / 4, or 11 in.  The area of a square of side s is A = s^2, so we have:

Here, V = (11 in)^2 * (19 in) = 2299 in^2

Which is a simplified form of the expression 5x – 12 + 18x – 4?

<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ You may have forgotten to add the options

However, you can collect like terms

In other words, collect the 'x' values and collect the numbers

5x + 18x = 23x

-12 - 4 = -16

Thus, your answer would be 23x - 16.

Any further questions, let me know.

Solve the system by finding the determinants and using Cramer's Rule:<br> 2x - y = 4<br> 3x + y = 1
Ahat [919]

Answer:

<em>(1, - 2) </em>

Step-by-step explanation:

2x - y = 4

3x + y = 1

A = \left[\begin{array}{cc}2&-1\\3&1\end{array}\right] = 2(1) - 3( - 1) =2 + 3 = 5

A_{x} = \left[\begin{array}{cc}4&-1\\1&1\end{array}\right] = 4(1) - 1(- 1) = 4 + 1 = 5

A_{y} = \left[\begin{array}{cc}2&4\\3&1\end{array}\right] = 2(1) - 4(3) = 2 - 12 = - 10

<em>x </em>= \frac{A_{x} }{A} =<em> 1</em>

<em>y </em>= \frac{A_{y} }{A} = <em>- 2</em>

<em>(1, - 2)</em>
