A carpenter is constructing a staircase in a house. The distance from the first floor to the basement is 9.2 feet. The staircase will be 13.3 feet long. What angle do the stairs make with the basement floor?

Answer:

[tex]x=\frac{9}{25}[/tex]

x = 0.36

Step-by-step explanation:

5x/3 + 2/5 = 1

5x/3 + 2/5 - 2/5 = 1 - 2/5

[tex]\frac{5x}{3} = 0.6[/tex]

5x/3 × 3 = 0.6 × 3

5x = 1.8

5x ÷ 5 = 1.8 ÷ 5

[tex]x=\frac{9}{25}[/tex]

x = 0.36

Answer:

it is approximately 12.57meters

Answer:

12.56 meters

Step-by-step explanation:

The area of a circle is πr², where r is the radius of the circle.

First we square the radius, which is 2. 2²=4.

Now our area is 4π.

Using 3.14 for π, we can say the area is 4 × 3.14, which is equal to 12.56

Answer:

A = 3 + 9/10

B = -(3 + 3/10)

Step-by-step explanation:

We have two numbers, A and B, such that:

A + B = 3/5

A - B = 7 + 1/5

To solve this, we first need to isolate one of the variables in one of the equations, I will isolate A in the first equation:

A = 3/5 - B

Now we can replace this in the other equation:

A - B = 7 + 1/5

(3/5 - B) - B = 7 + 1/5

3/5 - 2*B = 7 + 1/5

-2*B = 7 + 1/5 - 3/5

-2*B = 7 - 2/5 = 35/5 - 2/5 = 33/5

B = -(33/5)/2 = -33/10 = - 30/10 - 3/10 = -3 - 3/10 = -(3 + 3/10)

Now that we know the value of B, we can use the equation

A = 3/5 - B

To find the value of A:

A = 3/5 - ( -(3 + 3/10))

A = 3/5 + (3 + 3/10)  = 6/10 + 3 + 3/10 = 3 + 9/10

The numbers are:

A = 3 + 9/10

B = -(3 + 3/10)

Answer:

Number of 1/8 cups of sugar needed = 2

Number of 1/8 cups of whole wheat flour needed = 6

Number of 1/8 cups of all purpose flour needed = 4

Step-by-step explanation:

Recipes Kelly needs:

Sugar = 1/4 cups

Whole wheat flour = 3/4 cups

All purpose flour = 1/2 cups

She could only find her ⅛ cup measuring cup.

How many ⅛ cups will she need for each ingredient?

Number of 1/8 cups of sugar needed = cups of Sugar needed / 1/8 cups

= 1/4 ÷ 1/8

= 1/4 × 8/1

= 8/4

= 2

Number of 1/8 cups of sugar needed = 2

Number of 1/8 cups of whole wheat flour needed = cups of whole wheat flour needed / 1/8 cups

= 3/4 ÷ 1/8

= 3/4 × 8/1

= 24/4

= 6

Number of 1/8 cups of whole wheat flour needed = 6

Number of 1/8 cups of all purpose flour needed = cups of all purpose flour needed ÷ 1/8 cups

= 1/2 ÷ 1/8

= 1/2 × 8/1

= 8/2

= 4

Number of 1/8 cups of all purpose flour needed = 4

Answer:

B. experimental probability

Step-by-step explanation:

It wasn't A because the coin was flipped making it an experiment.

Option C is just wrong.

So that leaves you with option B as your answer.

Answer:

d. 18x^3-27x^2y

Step-by-step explanation:

(3x)^2(2x-3y)

work out the first term

9x^2(2x-3y)

distribute

18x^3-27x^2y

Answer:

(d.) [tex]18x^3-27x^2y[/tex]

Step-by-step explanation:

When given the following equation,

[tex](3x)^2(2x-3y)[/tex]

Systematically perform the operations. Use the order of operations, the order of operations states the following,

1. Parenthesis

2. Exponents/ radicals

3. Multiplication/ Division

4. Addition/ Subtraction

Remember, when performing an exponential operation, one multiplies the base by itself the number of times the exponent indicates. In the given equation, perform the exponent by multiplying the base (3x) by itself twice.

[tex](3x)^2(2x-3y)\\\\(3x)(3x)(2x-3y)\\\\(9x^2)(2x-3y)[/tex]

Now distribute, multiply every term inside the parenthesis by the term outside of it

[tex](9x^2)(2x-3y)\\\\(9x^2)(2x) + (9x^2)(-3y)\\[/tex]

Simplify,

[tex]18x^3-27x^2y[/tex]

Therefore the solution is (d.) [tex]18x^3-27x^2y[/tex]

Answer:

The answer is 360

Step-by-step explanation:

the formula for the volume of a rectangular based pyramid is 1/3 times the base area times the height and the height is given as 15 cm the base parameters are 9 and 8 respectively so deep area of the rectangular base is 9 * 8 * 15 that is 1080 x 1/3 which is 360

Answer:

Net Earnings = $65

Step-by-step explanation:

Money deposited in saving account = $2500

Interest rate = 5% pa = 5% of 2500 = $125

Fee = $5 (monthly). So annual fee = 12 x 5 = $60

So, net earning = Interest Earning - Annual Fee

= $125 - $60 = $65

Answer:

B.

Step-by-step explanation:

If x is a number, then twice a number is 2x. The difference between 17 and 2x is 17-2x.

Common Error:

A. says 17 less than twice a number. Since it is 17 less, it is 2x-17 not 17-2x.

Hope this answer helped! :)

Answer:

23.25 m^3

Step-by-step explanation:

First you must find the area of the base you find it like this:

A(area)=1/2(one half)3.1(base)2.5(height)

you get 3.875(this is the area of the base)

now you have to multiply the area of base times the area of height like this:

A(area)=3.875(area of base)6(height)=23.25

so the answer is 23.25m^3

Hope I'm right have a great day!

Answer:

Step-by-step explanation

Ok I am not so sure about this one, since this was a LOT of counting, and unless you want to see 5 pages of calculations, I'm just going to go on a limb and say trust me. However, if you really want to see for yourself, I'll give you a hint. For the first 1***1 numbers, the sum is 1440. For the 2***2 numbers, the sum is 1683. Try to calculate this to 9***9 to find the answer! Again, not sure about my answer if it's wrong, sorry!

None of the above

Step-by-step explanation:

Measure of one base angle: 52°

Measure of the other base angle: 52°

Measure of the third angle: x

Sum of the measures of the three angles: 180°

Equation:

x + 52 + 52 = 180

x + 104 = 180

Answer: None of the above

Answer:

Half of 6 is 3(new radius)

3^3 = 9

9 x 3.14 = 28.26(area of circle)

Now we multiply by height

28.26 x 5 = 141.3

Now we divide by 3 since its part for the formula of finding the cone's volume:

141.3 x 1/3(basically just dividing by 3) = 47.1

Now let's find the volume of the cylinder:

3^3 = 9, 9 x 3.14 = 28.26

28.26 x 14 = 395.64

Now let's add the given volumes:

395.64  + 47.1 = 442.74 cm^3 is your answer.
