Can someone please find the volume of this shape and show work for how you did it??
castortr0y [4]

Answer:

221.4m^{3}

Step-by-step explanation:

To work out the volume of this shape you will first need to work out the area of the triangle. To work out the area of the triangle you would multiply the base of 12 by the height of 4.1, which gives you 49.2. You would then need to divide 49.2 by 2, which gives you 24.6. This is because the formula for the area of a triangle is the same as that of a square, however a triangle is half of a square with the same length and width. To work out the volume you would multiply the area of the triangle, which is 24.6 by the height of 9, which gives you 221.4m^{3}

1) Multiply 12 by 4.1.

12*4.1=49.2

2) Divide 49.2 by 2.

49.2/2=24.6

3) Multiply 24.6 by 9.

24.6*9=221.4m^{3}

jamerra received a $3,00 car loan. she plans on paying off the loan in 2 years. at the end of 2 years, jamerra will have paid $4
leonid [27]

The rate of interest is 75 % per year

<em><u>Solution:</u></em>

Given that, Jamerra received a $3,00 car loan

she plans on paying off the loan in 2 years

<em><u>Jamerra will have paid $450 in interest</u></em>

Therefore, we get

Principal = $ 300

Number of years = 2

Simple Interest = $ 450

Rate of interest = ?

<em><u>The simple interest is given by formula:</u></em>

simple\ Interest = \frac{p \times n \times r}{100}

Where,

"p" is the principal and "n" is the number of years and "r" is the rate of Interest

<em><u>Substituting the given values we get,</u></em>

450 = \frac{300 \times 2 \times r}{100}\\\\450 = 3 \times 2 \times r\\\\6r = 450\\\\r = \frac{450}{6}\\\\r = 75

Thus rate of interest is 75 % per year

Carl is going to make a frame for a picture. The dimensions of the frame need to be 2 feet by 18 inches. How long must the board
MArishka [77]
The perimeter of an object is found by adding all of the sides.  The sides of his frame would be 2 ft, 2 ft, 1.5 ft (18 inches / 12 inches per foot = 1.5 feet), 1.5 feet.  Adding these together we get a total length of 7 feet.  However, he may want to use a slightly longer board to account for any errors!
