Answer:

for number one the answer is D). 1,250 sq ft. for number 2 it is A.) 125 ft

Thats all you really need to answer, it doesnt ask for you to explain it or anything.

Step-by-step explanation:

. We assume, that the number 10 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 10 is 100%, so we can write it down as 10=100%.

4. We know, that x is 0.034% of the output value, so we can write it down as x=0.034%.

5. Now we have two simple equations:

1) 10=100%

2) x=0.034%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

10/x=100%/0.034%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 0.034% of 10

10/x=100/0.034

(10/x)*x=(100/0.034)*x - we multiply both sides of the equation by x

10=2941.1764705882*x - we divide both sides of the equation by (2941.1764705882) to get x

10/2941.1764705882=x

0.0034=x

x=0.0034

now we have:

0.034% of 10=0.0034

Step-by-step explanation:

Identification of given pairs of angles are as follows:

∠1 and ∠10: Corresponding angles

∠6 and ∠12: Alternate exterior angles

∠8 and ∠10: Alternate interior angles

∠4 and ∠11: Alternate interior angles

∠2 and ∠8: Alternate exterior angles

Assuming you meant to say triangle ABC is congruent to triangle DEF, then the corresponding pieces AB and DE are the same length.

In short AB = DE.

Since DE = 10, this makes AB = 10 also.

Answer:

4

Step-by-step explanation:

x²=16

x=√16

x=4

Answer:

x^2=16

^ stands for power or exponent

so, the equation is: x square= 16

for this x should be equal to 4

now,

4^2=16

Step-by-step explanation:

Answer:

slope is -2

and y-intercept is 13

Step-by-step explanation:

[tex]slope=m=\frac{y_2-y_1}{x_2-x_1} \\m=\frac{5-3}{4-5}=\frac{2}{-1}\\slope=m= -2\\Then, we can write equation of line as y=mx+b\\y=-2x+b\\using either points given we can find b \\so using point (4,5)\\5=-2(4)+b\\so b=13\\ therefore y-intercept is = 13[/tex]

Answer:

I want to say it is 8,000

Step-by-step explanation:

go to 80 degrees and go up to the next point and that is on 8,000

Answer:

8,300

Step-by-step explanation:

If you continue the graph to 80 degrees, your average will end up at 8,300. You can tell because it will be above 8,000 but not close to 9,000 so it has to be 8,300.

Answer:

y= -2x+6

Step-by-step explanation:

use point slope form ----> y-y,=m(x-x,)

(the commas serve as ones)

y-4= -2(x-1)

use distributive property

y-4= -2x+2

add 4 to each side

y= -2x+6

The solution of the trigonometric inequality will be equal to π / 4.

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relation between variables and the numbers.

The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.

Given inequality is 3 - tanx ≥ 4 - 2tanx. The inequality will be solved as,

3 - tanx ≥ 4 - 2tanx

2tanx - tanx ≥  4 - 3

tanx ≥ 1

tanx ≥  tan(π/4)

x ≥ (π/4)

Therefore, the solution of the trigonometric inequality will be equal to π / 4.

Given :

For the school's sports day, a group of students prepared 12 1/2 litres of lemonade. At the end of the day they had 2 5/8 litres left over.

To Find :

How many litres of lemonade were sold.

Solution :

Initial amount of lemonade, I = 12 1/2 = 25/2 litres.

Final amount of lemonade, F = 2 5/8 = 21/8 litres.

Amount of lemonade sold, A = I - F

A = 25/2 - 21/8 litres

A = 9.875 litres

Therefore, 9.875 litres of lemonade were sold.

Hence, this is the required solution.

Answer:

There is 7.5% increase in the number of songs on his mp3 player.

Step-by-step explanation:

Original Songs in mp3= 440 songs

Final Songs in mp3= 473 songs

We need to find percent of increase in the number of songs on his mp3 player.

The formula used is: [tex]Percent \ of \ increase = \frac{Final \ Value \ -\ Original \ Value}{Original \ Value} \times 100[/tex]

Now putting values and finding percent of increase

[tex]Percent \ of \ increase = \frac{Final \ Value \ -\ Original \ Value}{Original \ Value} \times 100\\Percent \ of \ increase = \frac{473-440}{440} \times 100\\Percent \ of \ increase = 7.5\%[/tex]

So, there is 7.5% increase in the number of songs on his mp3 player.

Answer:

A, and D

Step-by-step explanation:

If you go through all the problems, just replace "b" with "(4)" into a calculator. For A and D, they both equaled 180.

The expression that has a value of 180 when b = 4 is D. 51b−24

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

87b - 179 + 957/87.

= 87(4) - 179 + 857/87.

= 348 - 179 + 9.85, will not be 180.

33b12, will not be 180 at b = 4.

b² + 120,  will not be 180 at b = 4.

51b - 24.

= 51(4) - 24.

= 204 - 24.

= 180.

11b + 187 - 1756/13.

= 11(4) + 197 - 135.07, will not be 180 at b = 4.

Answer:

No solutions (roots)

Step-by-step explanation:

The root of an equation is basically the solution of the equation. If I'm reading the problem correctly, the equation is (6+x)*2 - x*2 = 168.

We distribute the (6+x)*2 part and get 12+2x - 2x = 168. Uh oh.. the 2x terms cancel each other out and we are left with 12=168. Either I'm reading the equation wrong or the equation has no solutions.
