The area of a circle is 28.26 cm2. What is the circle's radius?
(Take = 3.14)
The radius of the circle is
cm.

Answer:

x = 90

Step-by-step explanation:

A line will ALWAYS equal 180 degrees, so we know that one angle is <90 and we have to find x, which is the other angle of the line.

So, x + 90 = 180

You can either solve the equation for x or you can just subtract 90 from x, which is the easier way.

180 - 90 = 90

So, x = 90

Answer:

choice 3

Step-by-step explanation:

Answer:

Fourth Option

Step-by-step explanation:

The perimeter of a shape is all sides added. So, if you do 2x + 2x + (x+1) + (x+1), you would get 6x+2. To get the answer to the question, you verify to see which one of the options equal to 6x+2.

First option:

2x(x+1) and 2(2x) + 2(x+1). You find what this equals. 2x(x+1) = 2x^2+2x so we can automatically elimate this one.

Second option:

2x(x+1) and 2x+2x+2x+1. Here again you see 2x(x+1) which equals 2x^2+2x and is not correct so we eliminate this.

Third option:

4x(2x+2) and 2x(x+1) + 2x(x+1). Once more you see 2x(x+1) but added to 2x(x+1) which would basically equal 2x^2+2x *2. Therefore, it's not this one.

Fourth option:

6x+2 and 2x+(x+ 1) +2x + (x+ 1). Now this one looks right because we already got 6x+2 and this is the only option that presents that but also because we initially solved 2x + 2x + (x+1) + (x+1) and this equals 2x+(x+ 1) +2x + (x+ 1).

I guess you don't really have to solve each of them you can kinda see and tell that the last one seems right but if you're not sure you should use the process above.

I hope this helped!

Answer:

The Civil Rights Movement was a social movement in the U.S. that fought to end racial segregation and discrimination against African-Americans. While we continue to recognize the leaders of this movement and those who contributed, the men of the movement are far more celebrated and remembered than the women. In this informational text, Barrett Smith discusses the role that women played in the Civil Rights Movement.

Answer:

-4/5 = x

Step-by-step explanation:

Answer:

3/2

Step-by-step explanation:

x = 3x + 4 - 1

we can subtract 1 from 4

x = 3x + 3

subtract 3x from both sides

-2x = 3

divide both sides by -2

x = -3/2

so -x would equal -(-3/2) = 3/2

Answer:

At least 7 shirts would need to be sold to cover their costs

Step-by-step explanation:

Cost of producing x t-shirts.

The cost of producing x t-shirts is a flat fee of 35 plus 4.25 per t-shirt. So

[tex]C(x) = 35 + 4.25x[/tex]

Earnings of selling x t-shirts:

Charges $10 per t-shirt, so it earns 10 for each t-shirt it sells.

[tex]E(x) = 10x[/tex]

How many shirts would need to be sold to cover their costs?

To cover the costs, we need that the earnings are equal or higher than the costs. So

[tex]E(x) \geq C(x)[/tex]

[tex]10x \geq 35 + 4.25x[/tex]

[tex]5.75x \geq 35[/tex]

[tex]x \geq \frac{35}{5.75}[/tex]

[tex]x \geq 6.09[/tex]

Since we cannot sell a decimal part of a shirt, at least 7 shirts would need to be sold to cover their costs

Answer:

10:2, 15:3, 20:4, etc.

Step-by-step explanation:

Well just keep going, they all simplify back to 5:1

The required equivalent ratios are,

[tex]10:2\\15:3\\20:4\\[/tex]

Equivalent ratios are the ratios that are the same when we compare them. Two or more ratios can be compared with each other to check whether they are equivalent or not.

For example, 1:2 and 2:4 are equivalent ratios.

The given ratio is,

[tex]5:1[/tex]

Now, as we know that we can convert the given ratio into fractions.

[tex]\frac{5}{1}[/tex]

Now, for finding the equivalent ratios multiply the same constant in both the numerator and denominator.

So, the required ratios are,

[tex]\frac{5\times2}{1\times 2} =\frac{10}{2}=10:2\\ \frac{5\times3}{1\times 3} =\frac{15}{3}=15:3\\\frac{5\times4}{1\times 4} =\frac{20}{4}=20:4\\[/tex]

And so, on.

Answer: b

Step-by-step explanation:

By the alternate interior angles theorem, the angle of elevation and the angle of depression have the same measure.

The measure of angle A is 32 degrees or the measure of the angle of elevation is 32 degrees option (b) 32 degrees is correct.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

It is given that:

The right-angle triangle is shown in the picture.

The right-angle triangle is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.

As the two lines are parallel to each other and a transversal is intersect the parallel lines so the angle would be same as 32 degrees

The angle A = 32 degrees

Thus, the measure of the angle A is 32 degrees or the measure of the angle of elevation is 32 degrees option (b) 32 degrees is correct.

Answer:

1.2%

Step-by-step explanation:

Solving our equation

r = 10.2 / ( 425 × 2 ) = 0.012

r = 0.012

converting r decimal to a percentage

R = 0.012 * 100 = 1.2%/year

The interest rate required to

accumulate simple interest of $ 10.20

from a principal of $ 425.00

over 2 years is 1.2% per year.
