plzzz help me i need to do this for homework thank you :)

Check the picture below.

so the pyramid has a base area of "B" and a height of "h", thus

\(\textit{volume of a pyramid}\\\\ V=\cfrac{Bh}{3} ~~ \begin{cases} B=\stackrel{base's}{area}\\ h=height\\[-0.5em] \hrulefill\\ B=\frac{1}{2}(x)(6)\\[1em] h=9\\ V=99 \end{cases}\implies 99=\cfrac{1}{3}\stackrel{B}{\left[\cfrac{1}{2}(x)(6) \right]}(\stackrel{h}{9}) \\\\\\ 99=\cfrac{1}{3}(3x)(9)\implies 99=9x\implies \cfrac{99}{9}=x\implies 11=x\)

Answer:

11

Step-by-step explanation:

The formula for a triangular pyramid is:

V = 1/3 × base area × height

(base area is base × height ÷ 2 so x × 6 ÷ 2)

99 = 1/3 × 6x/2 × 9 divide equation by 9

÷9 ÷9

3(11 = 1/3 × 6x/2) multiple equation by 3

(33 = 6x/2) multiple by 2

66 = 6x divide by 6

÷6 ÷6

11 = x

Answer:

y=4x+3.....hope this helps ; )

Step-by-step explanation:

Answer:

y = 4x +b

Step-by-step explanation:

The question asks you to write in slop intercept form which is y = mx+b so first you ahve to solve for the slope (m) and the formula for that is m = y2-y1/x2-x1

and bascially you plug in any points that are on the table and use the y's and x's

so im going to use the first two points

m =  (11-7) / (2-1)

   = 4 / 1

   = 4

so the slope equals four and we can plug that into our slope intercept equation

y = 4x + b and now we need to slove for b the y intercept and we can do that by plugging in any points from the table into our equation (to understand why this works probaly ask you teacher for a in-depth explination)

im going to use the first points again and plug it into our equation

7 = 4(1) + b (mutiply 1 by four)  

7 = 4 +b (isolate b so subtract four from each side)

-4   -4

3 = b so we now know the slope and the y intercept so our equation in slope intercept form will be y = 4x +3

Answer:

Step-by-step explanation:

The correct option is C More than 12.5 Weeks Let x be the number of weeks, then 200 − 2 x < 175 ⇒ 2 x > 200 − 175 ⇒ 2 x > 25 ⇒ x > 12.5 So, More than 12.5 Weeks is the answer.

ANSWER 12

Answer:

Step-by-step explanation:

A.13w, 13 weeks will get him down to 174lbs, 12 weeks would only get him 176lbs, so the minimum/full amount of weeks he needs to get down to less than 175lbs is 13.

Equation:

w=2

13w=26

200-26=174.

Answer: 6

Simple Explanation:

To find 75% of 8, just multiply 8 by 0.75 (which is the same as 75%).

8 x 0.75 = 6

Answer:

5 pitchers

Step-by-step explanation:

As you can see, there is data for 5 different pitchers (each listed separately on the x / horizontal axis)

So, there are 5 pitchers--regardless of how many innings they each pitched (unless one of them theoretically pitched 0 innings, but that is not the case)

well, Yasin is correct, the exterior angles are all 36° each, however "g" is including more than just that, Check the picture below.

Answer: 36 is wrong

Step-by-step explanation: 360 - 36 = 324  degrees

Here is the order

Step-by-step explanation:

Under these conditions, plant B produced 12000 panels

We are told that 3% of the 9000 panels in plant A and 10% of "x" quantity in plant B are defective.
As it is not known how much plant B produces, but it is known that the grand total of defects is 7%, the total defective of separate plants are added and the value is equaled to the grand total of defects.

\(\begin{array}{l}\sf 0.03\times 9000 + 0.1b = 0.07\times(9000+b)\\\sf 270 + 0.1b = 630 + 0.07b\\\sf 0.1b-0.07b = 630-270\\ \sf 0.03b=360\\\raisebox{6pt}{$\sf b=\dfrac{360}{0.03}$}\\\therefeore\bf b=12000~panels\end{array}\)

So, plant B produces 12000 panels

Step-by-step explanation:

Distribute then add like terms.

Answer:

In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.

Answer:

x = 1 and y = 4

Step-by-step explanation:

Multiply the top equation by 7 on both sides, and then cancel it out:

7(5x + y) = 7(9)

35x + 7y = 63

Now use this equation to cancel out -7y on the second equation:

35x + 7y = 63

10x - 7y = -18

45x = 45

x = 1

Now that we have our x-value, we can plug it into one of our two original equations:

5(1) + y = 9

y = 4

I’m done with high school

Step-by-step explanation:

Literally it was horrible when i was in middle school and elementary school

Answer:You just divide the original amount by 100 (move the decimal point over two places)

750 / 100 = 7.5

Now you multiply that by the interest rate, which in this case is 7.

7.5 x 7 = 52.5

Now finally, you multiply that by the amount of years. In this case, 3.

52.5 x 3 = 157.5

That would be the amount added after three years! Remember, this is simple interest. Compound interest is a little more complex.

Step-by-step explanation: I hope this helps.
