x=?..................​

Answer:

24

Step-by-step explanation:

Answer:

25. [tex]27a^{3}b^{2}[/tex]

26. [tex]3\pi x^{3}y[/tex]

Step-by-step explanation:

For 25:

[tex]A = \frac{a+b}{2} h[/tex]  (area of a trapezoid)

[tex]A=\frac{11a^{2}b+7a^{2}b}{2} *3ab[/tex]  (substitute terms)

[tex]= \frac{18a^{2}b}{2}*3ab[/tex]  (collect like terms)

[tex]= 9a^{2}b*3ab[/tex]  (reduce the fraction by crossing out 2)

[tex]= 27a^{3}b^{2}[/tex]  (calculate)

For 26:

[tex]A=\pi r^{2}[/tex]  (equation of area of a circle)

[tex]A=\pi (3x^{3} y)^{2}[/tex]  (enter the radius)

[tex]= 3\pi x^{3} y[/tex]  (communtative property to reorder the terms)

Answer:

12

Step-by-step explanation:

Pythagoras Theorem is clearly used in this question.

To Calculate the Hypotenuse:

C = [tex]\sqrt{a^2+b^2}[/tex]

The Adjacent angle has already given as 9, so you can factor that into the question.

In Order to calculate the Opposite angle you need to use the following formula.

[tex]b = \sqrt{c^2-a^2}[/tex]

With the integers we already have for both Hypotenuse and Adjacent factored in this will be your equation:

[tex]b = \sqrt{15^2-9^2} = 12[/tex]

Therefore you answer is 12, Hope this helps, feel free to make as brainilest.

Answer:

The number of 5-inch cuts if duct tape remainding is 14.

Step-by-step explanation:

1. 96 - 22.5 = 73.5

2.  73.5/5 = 14.7

3. .7 isnt a full piece of tape, so he has 14 5inch tapes

Answer:

x = 15

Step-by-step explanation:

Assuming 3x and x-60 are in degrees, you can use:

cos(a) = sin(a+90)

To rewrite the equation as:

sin(3x) = sin(x-60+90)

sin(3x) = sin(x+30)

3x = x+30

2x = 30

x = 15

But, solving 3x = x+30 which simplifies to x=15 is not the only solution to this equation, as you can see in below picture. Finding all solutions is a bit more work, but maybe that is not required in your case.

Answer:

25.6

Step-by-step explanation:

16*2=32

32*0.8=25.6

Answer:

25.6

Step-by-step explanation:

16x.8=12.8

because he makes it every half mile we have to multiply by 2\

12.8*2=25.6

if he walks 16 miles he makes 25.6

Answer:

it's three hope it helps

Step-by-step explanation:

answer: 3.8857

explanation:

Simplifying

-5k + 2.9 = -12k + 30.1

Reorder the terms:

2.9 + -5k = -12k + 30.1

Reorder the terms:

2.9 + -5k = 30.1 + -12k

Solving

2.9 + -5k = 30.1 + -12k

Solving for variable 'k'.

Move all terms containing k to the left, all other terms to the right.

Add '12k' to each side of the equation.

2.9 + -5k + 12k = 30.1 + -12k + 12k

Combine like terms: -5k + 12k = 7k

2.9 + 7k = 30.1 + -12k + 12k

Combine like terms: -12k + 12k = 0

2.9 + 7k = 30.1 + 0

2.9 + 7k = 30.1

Add '-2.9' to each side of the equation.

2.9 + -2.9 + 7k = 30.1 + -2.9

Combine like terms: 2.9 + -2.9 = 0.0

0.0 + 7k = 30.1 + -2.9

7k = 30.1 + -2.9

Combine like terms: 30.1 + -2.9 = 27.2

7k = 27.2

Divide each side by '7'.

k = 3.885714286

Simplifying

k = 3.885714286

Answer:

135 minutes

Step-by-step explanation:

The total number of minutes Tim needs to practice is 300 minutes.

We subtract the number of minutes he has already finshed:

300 - 127 - 38 = 135 minutes

Answer:

138 minutes

Step-by-step explanation:

so all we have to do is subtract the times he practiced for on sunday and tuesday by 300

300-127-38=138

he still has to practice 138 minutes to reach his goal

Answer:

37,500 and non recurring

Step-by-step explanation:

The Riley's will pay a total of $7,500 in costs for the closing costs and $30,000 down payment on their mortgage.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, Rileys are buying a home that costs $250,000.

12% for a down payment

So, down payment is

12% of 250,000

= 12/100 ×250,000

= 12×2500

= $30,000

They are paying 3% in closing costs

3% of 250,000

= 3/100×250,000

= $7,500

Therefore, the Riley's will pay a total of $7,500 in costs for the closing costs and $30,000 down payment on their mortgage.

Step-by-step explanation:

Answer:

[tex](x+5)^{2} = 9[/tex]

Step-by-step explanation:

To complete the square you need to add [tex]\frac{b}{2}^{2}[/tex]to both sides. (Parenthesis around b/2)

b = 10

b/2 = 5

(b/2)^2 = 25

[tex]x^{2}[/tex] +10x + 16 = 0

subtract 16 to both sides

[tex]x^{2}[/tex] + 10x = -16

add 25 to both sides

[tex]x^{2}[/tex] +10x + 25 = 9

Perfect Square Trinomial Factoring

[tex](x+5)^{2}[/tex] = 9

Steps:

solve for x=3

(3,5)

solve for X=7

(7,-19)

then find the slope using

[tex] \frac{y2 - y1}{x2 - x1} [/tex]

and it will be = -6

Answer:

Step-by-step explanation:

okay, so here are a few methods you can use.

___

1) +

x + 7 = 10 so because this is addition we use the reverse, subtraction. So

x - 7 = 10 - 7 and that equals to 3.

2) -

x - 2 = 10 so because this is subtraction we do the reverse, addition.

x + 2 = 10 + 2 and that equals to 12.

3) x

x times 3 = 21 because this is multiplying we divide.

x/3 = 21/3 and that would be 7.

4) /

x/2 = 10 same as above, reverse is multiplying.

x times 2 = 10 times 2 and thats 20.
