The lateral area of a right cylinder having a base diameter of 10 units and height of 10 units is:

Answer:

$121,500

Step-by-step explanation:

If the value increases by 5% every year, then in 61 years  it will increase by

5% * 61 years = 305%

301% of %30,000  is $91,500

$(30,000 + 91,500)

= $121,500

Answer:

x = 10,-4

Step-by-step explanation:

(x-3)^2 -49 = (x-3-7)(x-3+7)

= (x-10)(x+4)

The zeros of f(x) are 10 ,-4

This problem can be solved by following steps

[tex]f(x)=0\\(x-3)^{2}-49=0\\ x^{2} -6x-40=0\\x^{2} -10x+4x-40=0\\x(x-10)+4(x-10)\\(x-10)(x+4)\\x = 10 , -4[/tex]

Hence the zeroes are 10 and -4

Answer:

Step-by-step explanation:

We first need to come up with a system of equations that models this situation. Let's call apple pies "a" and lemon pies "L". Then we look to each individual involved in selling these pies and come up with an equation for each. Scott sold 3 apple and 12 lemon pies. The combination of this number of these 2 types of pies grossed him $141. In equation form, the combination of this number of these 2 types of pies is an addition thing. Namely,

3a + 12L = 141

For Paul, his combination was 2 apple and 5 lemon for a total of $64. His equation is

2a + 5L = 64

We need to solve this system either by substitution or elimination/addition to come up with the cost of both types of pies. I chose elimination/addition because I think in this case it is easier, and easier is good.

Setting up for elimination/addition:

3a + 12L = 141

2a  + 5L = 64

Let's first eliminate the a terms. That means that the coefficient on each a has to be the same but with different signs. The LCM of both 3 and 2 is 6, so we will multiply the top equation by 2 and the bottom equation by -3 (we could also have chosen to eliminate the L's first; we also could have chosen to eliminate the a's first but made the 2 negative instead of the 3. As long as you do the math correctly, you'll get the same answer regardless of how you choose to do it). Multiplying the first equation by 2 and the second by -3 gives us a new system:

6a + 24L = 282

-6a - 15L = -192

The reason this is called the elimination or addition method is because the goal is to eliminate, but you do that by adding the columns together. As you can see, 6a - 6a eliminates the a terms, right? What you're left with then is

9L = 90 and

L = 10

Now that we know the cost of a lemon pie, we can back sub in to solve for the cost of an apple pie. It doesn't matter which equation you back sub into, as long as it has both an L and an a in it.  I'll choose the first equation we wrote when we took on this nightmare:

3a + 12L = 141.  Subbing in 10 for L gives us

3a + 12(10) = 141 and

3a + 120 = 141 and

3a = 21 so

a = 7

That means that lemon pies cost 10 each and apple pies cost 7 dollars each.

The diameter is 12 so the radius is  d/2 = 12/2 = 6

V = 4/3 pi 6^3

V = 288 pi

Let pi = 3.14

V =904.32

Answer:

it is 80 degrees for first and then 105 degrees for second

Step-by-step explanation:

The measure of ∠BAC is 105°.

Given that, ∠DAC=(x-20)°=25° and ∠DAB=(2x-10)°.

The two angles are said to be adjacent angles when they share the common vertex and side.

Now, ∠DAC=(x-20)°=25°

⇒x=45°

So, ∠DAB=(2x-10)°=80°

Then ∠BAC=∠DAC+∠DAB=25°+80°=105°

Therefore, the measure of ∠BAC is 105°.

3x -1 =11

Add 1 to each side

Step-by-step explanation:

Answer:

0.05x+0.25y=8.75; the y intercept represents that if she found 0 nickels she must have found 35 quarters.

Step-by-step explanation:

1. Solve for y:

0.25y= 8.75-0.05x (subtract 0.05x on both sides)

y= (8.75-0.05x)/0.25 (divide by 0.25 on both sides)

2. Since the y intercept can be found when x equals 0, plug in 0 for x into the equation.

y=(8.75-0.05(0))/0.25

y= 8.75/0.25

y=35

Answer:

9.6 ounces butter

8 ounces sugar

12 ounces flour

4 eggs

Step-by-step explanation:

I'm going to write them down so it's easier for me to look at.

12 ounces butter

10 ounces sugar

15 ounces flour

5 eggs

Now make a ratio: 12 : 15 = 4 : 5

Apply this to all of the ingredients.

12 * 0.8 = 9.6

10 * 0.8 = 8

15 * 0.8 = 12

5 * 0.8 = 4

Answer:

Below in bold.

Step-by-step explanation:

12 is  12/15 = 4/5 of 15 so you multiply the amounts of each ingredient by 4/5 or 0.8.

Butter: 12 * 0.8 = 9.6 oz.

Sugar:  10 * 0.8 = 8 oz.

Flour:  15 * 0.8 = 12 oz.

Eggs: 5 * 0.8 = 4 eggs.

Answer:

  0.1948° in each exterior angle

Step-by-step explanation:

The exterior angle measure is 360° divided by the number of sides. Here, that is 10x, so the exterior angle is ...

  360°/(10x) = 36°/x

The measure of the interior angle is the supplement of the exterior angle, so we have ...

  x -5 = 180 -(36/x)

  x(x -5) = 180x -36 . . multiply by x

  x^2 -185x = -36 . . . . . subtract 180x

  x^2 -185x +8556.25 = -36 +8556.25 . . . . complete the square

  (x -92.5)^2 = 8520.25

  x -92.5 ≈ ±92.3052

  x ≈ 184.8052 or 0.19480

It does not make any sense for the number of sides to be 10·0.1948 = 1.948, so we assume the number of sides is 184.8052·10 = 1848.

Then the number of degrees in each exterior angle is ...

  36°/184.8052 = 0.1948

Answer: The volume of the pyramid is 99.8 cubic feet.

Step-by-step explanation:

Hi, to answer this question we have to apply the next formulas:

Base area = side length^2 = 5.8^2 = 33.64 ft2

And then:

Volume of a pyramid = 1/3 x base area x height

Replacing with the values given:

V = 1/3 x 33.64 x8.9 =99.8 ft3

The volume of the pyramid is 99.8 cubic feet.
