The value of the equation 3ab - 9ab + 7ab is \boxed{ab}.

Further explanation:

There are two properties.

1. The property of addition or property of sum.

2. The property of subtraction.

3. The property of division.

4. The property of multiplication.

Given:

The equation is 3ab - 9ab + 7ab.

Explanation:

Consider the equation S = 3ab - 9ab + 7ab.

The equation contains the two variables that are “a” and “b”.

In the equation we have two operations one is addition and another is subtraction.

Solve the above equation to obtain the value of the equation.

First add 3ab and 7ab.

\begin{aligned}X&=3ab+7ab\\&=10ab\\\end{aligned}

Now subtract 9ab from 10ab.

\begin{aligned}S&=10ab-9ab\\&=1ab\\&=ab\\\end{aligned}

The value of S is ab.

Hence, the value of the equation 3ab - 9ab + 7ab is \boxed{ab}.

For the upcoming holiday season, Dorothy wants to mold 20 bars of chocolate into tiny pyramids. Each bar of chocolate contains 6
abruzzese [7]

Answer:

The largest  number of pyramids she can make from 20 bars of chocolate is:

  • <u>A. 180</u>

Step-by-step explanation:

Firstly, you must find the volume of the 20 bars of chocolate, remember that each bar contains 6 cubic inches of chocolate (6 in^3), so:

  • Volume of the bars = 6 in^3 * 20
  • <u>Volume of the bars = 120 in^3</u>

Now, you must find the volume of each pyramid, using the next formula:

  • Volume of a pyramid = 1/3 B * h

Where:

<em>B = area of the square base.</em>

<em>h = height of the pyramid.</em>

How these values are given in the problem, we only replace the values in the formula:

  • Area of a pyramid = 1/3 (1 in^2) * 2 in
  • <u>Area of a pyramid = 2/3 in^3</u>

Finally, we divide the volume of the bars in the volume of each pyramid:

  • Total number of pyramids = 120 in^3 / 2/3 in^3
  • <u>Total number of pyramids = 180</u>

I need help on 1-6 and If you can, can you explain how to do these? I'm not entirely sure how to.
gayaneshka [121]
1. Using c=2pi(r), plug in 7 for r and solve. Then using a=pi(r)^2, plug in 7 for r once again and solve.

2. First, the diameter (d) is 12 so to get the radius (r), divide 12 by 2 and you should get 6. Then use c=2pi(r) for circumference and a=pi(r)^2 for area to solve.

3. To get the area of the semicircle, divide 16 by 2 to get the radius (r), plug it into a=pi(r)^2, and divide the answer you get for a by 2. To get the area of the triangle, use a=1/2bh, plugging in 16 for b and 10 for h. Finally, add your two answers (the a's from the semicircle and triangle problems).

4. Multiply 20 by 5.5 to get the area of the triangle. Then multiply 4.5 by 20 to get the area of the parallelogram and add your two quotients.

5. Use a=1/2bh and plug in 4 for b and 3 for h and solve. Then multiply the quotient by 10 and there's your volume. To find the surface area, solve SA=(10×4)+(10×3)+(10×5)+12. All I did there was find the area of all the sides and added them together.

6. To find the triangle's volume, use a=1/2bh (b=4, h=1.5) and then multiply the quotient of that by 2.5. To find the rectangle's volume, use v=lwh (l=4, w=2.5, h=2) and solve. Finally, add the triangle's volume and the rectangle's volume to get the total volume. To get its surface area, start with the rectangle. Find the areas of all the sides and add them together but then subtract the 2.5×4 rectangle as it is not on the surface. It should look like this: SA=2(4×2)+2(2.5×2)+10. Again, all I did was find the areas of all the rectangle's sides on the surface and added them. Next, find the triangle's areas on the surface and it should look like this: SA=2(1.5×4)+2(2.5×2.5). Finally, add both values of SA from the triangle and rectangle and there's your surface area.

True [87]

Answer:

64 inch³

Step-by-step explanation:

3 / 2 = 1.5 radius

1.5²x π x 10 = 22.5 π = volume

22.5 π x 9/10 = 20.25π of water

= 63.6172512352
