Answer:

A

Step-by-step explanation:

You can probably figure out the rectangle of 16 by 8 so no explaining there. 16×8=128. You know that diameter of the cirkel is equal to y so 8. The diameter of a cirkel is two times its radius. so 8=2r. r=4. The area of a cirkel is calculated by the formula \pi×r^2. Fill in r=4 in \pi×r^2 gives us \pi×4^2=16\pi. You only have half of the cirkel so 16\pi/2=8\pi. 128+8\pi=153.12 which is A.

Answer:

No, primes cannot be divided by anything else then the number itself and one. Therefor you cannot divide it by any other prime.

Final answer:

A fraction with a numerator and denominator that are both prime numbers and different from each other cannot be simplified because there are no common factors to remove, as prime numbers only have 1 and themselves as factors.

Explanation:

If the numerator and denominator of a fraction are both prime numbers and are not equal to each other, the fraction cannot be simplified further. This is because prime numbers have only two factors: 1 and themselves. To simplify a fraction, you would prime factorize both the numerator and the denominator and then remove any common factors found in both.

However, since prime numbers have no other factors besides 1 and the number itself, and the two primes in our fraction are not equal, there are no common factors to remove. For example, in the fraction ⅓, both 3 and 5 are prime and there is no number other than 1 that can divide both. Hence, ⅓ is already in its simplest form.

Let's find out!

Step-by-step explanation:

**There is 128 fl oz in a gallon**

To solve, we will try and find the unit rate of 1 fl oz of both the cost of the water and the cost of the gasoline. A unit rate is when the denominator of a fraction is 1, showing how much of something equals 1 of the denominator. For example, if the cost was $1 for 1 fl oz, the cost of a gallon of gasoline would be $128.

[tex]\frac{cost(dollars)}{fl|oz}[/tex]

[tex]\frac{1.50}{16}[/tex] ÷ [tex]\frac{16}{16} = \frac{0.09375}{1} = \frac{0.09}{1}[/tex]

[tex]\frac{3.50}{16}[/tex] ÷ [tex]\frac{128}{128} = \frac{0.02734375}{1} = \frac{0.03}{1}[/tex]

For every 1 fl oz of water, it will cost $0.09

For every 1 fl oz of gasoline, it will cost $0.03

Which costs more?

To rewrite the equation 4^5 = 1024 as a logarithmic equation, we use the definition of a logarithm to get log4(1024) = 5, which indicates that 4 raised to the power of 5 equals 1024.

To rewrite the exponential equation 4^5 = 1024 as a logarithmic equation, we need to apply the definition of a logarithm which states that if b^y = x, then logb(x) = y. In this case, our base (b) is 4, the exponent (y) is 5, and the result (x) is 1024. Therefore, the equivalent logarithmic equation is log4(1024) = 5.

Remember that a logarithm essentially answers the question: To what exponent must the base be raised to produce a given number? Here, we are saying that 4 must be raised to the power of 5 to get 1024. This transformation from an exponential to a logarithmic form is a fundamental concept in mathematics, particularly when dealing with logarithmic scales and operations.

answer: second choice

Answer:

83 yards

Step-by-step explanation:

We are given;

We are required to determine the length;

That is;

P = 2 (L + W)

P = 2L + 2W

Rearranging the formula;

2L = P - 2W

Therefore;

2L = 294 yards - 2 (64 yards)

     = 294 - 128

     = 166

L = 166 ÷ 2

  = 83 yards

Thus, the length of the rectangle is 83 yards.

Answer:

The original price of the skirt is $24

Step-by-step explanation:

The complete question is

Jade buys a blouse and a skirt for 3/4 of their original price. Jade pays a total of $31.50 for the two items. If the original price of the blouse is $18, what is the original price of the skirt?

Let

x ----> the original price of the blouse

y ---> the original price of the skirt

we know that

Three fourth of the sum of the original price of the blouse and the original price of the skirt, must be equal to the total paid for the two items

so

The linear equation that represent this situation is

[tex]\frac{3}{4}(x+y)=31.50[/tex]

we have

[tex]x=18[/tex] ----> given problem

substitute the value of x in the expression above and solve for y

[tex]\frac{3}{4}(18+y)=31.50\\[/tex]

Multiply by 4 both sides

[tex]3(18+y)=4(31.50)\\54+3y=126\\3y=126-54\\3y=72\\y=24[/tex]

therefore

The original price of the skirt is $24

There are [tex]\frac{5}{12}[/tex] of these components together

Solution:

As a science experiment Mo and Jo want to send their rocket into space

They need 1/4 cup of water and 1/6 cup of a secret component

From given question,

[tex]\text{Cup of water} = \frac{1}{4}\\\\\text{Cup of secret component } = \frac{1}{6}[/tex]

How much is there of these two components together?

So we need to add these together

[tex]\text{Cup of water}+ \text{Cup of secret component } = \frac{1}{4} + \frac{1}{6}\\\\\text{Cup of water}+ \text{Cup of secret component } = \frac{1 \times 6}{4 \times 6} + \frac{1 \times 4}{6 \times 4}\\\\\text{Cup of water}+ \text{Cup of secret component } =\frac{6}{24} + \frac{4}{24}\\\\\text{Cup of water}+ \text{Cup of secret component } = \frac{6+4}{24} = \frac{10}{24} = \frac{5}{12}[/tex]

Thus there are [tex]\frac{5}{12}[/tex] of these components together

Answer:

Nathan use scale of 5 inches : 2 feet.

Step-by-step explanation:

Given:

Nathan drew a scale drawing of a hotel.

A room in the hotel is 55 inches long in the drawing.

The actual room is 22 feet long.

Now, to find the scale Nathan use.

The scale drawing of room = 55 inches.

The actual room = 22 feet.

Now, to get the scale Nathan use we set the ratio:

The scale drawing of room : The actual room.

= [tex]55\ inches:22\ feet[/tex]

[tex]=\frac{55}{22}[/tex]

[tex]=\frac{5}{2}[/tex]

[tex]=5\ inches:2\ feet.[/tex]

Therefore, Nathan use scale of 5 inches : 2 feet.

The scale factor Nathan used is 2/5.

To find the scale factor, we can set up a proportion using the length in the drawing and the actual length. Let x represent the scale factor. The proportion can be set up as follows:

55 inches / 1 = 22 feet / x

Cross multiplying, we get:

55 * x = 1 * 22

Simplifying, we have:

x = 22 / 55 = 2 / 5

Therefore, the scale factor Nathan used is 2/5.

Answer:

The slope of g(x) is: [tex]m=0[/tex]

The slope of f(x) is: [tex]m-1[/tex]

Step-by-step explanation:

For this exercise you need to know that:

1. By definition the slope of any horizontal line is zero ([tex]m=0[/tex])

2. The slope of a line can be calculated using the following formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

In this case, you can observe in the graph of the function g(x) given in the exercise that it is an horizontal line.  Then, based on the explanation given before, you can conclude that its slope is:

[tex]m=0[/tex]

To find the slope of the function f(x) shown in the table attached, you need to follow these steps:

- Choose two points  from the table:

[tex](0,3)[/tex] and [tex](4,-1)[/tex]

- You can say that:

[tex]y_2=-1\\y_1=3\\\\x_2=4\\x_1=0[/tex]

- Substitute values into the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]:

[tex]m=\frac{-1-3}{4-0}[/tex]

- Finally, evaluating, you get:

[tex]m=\frac{-4}{4}\\\\m=-1[/tex]

Answer:

The slope is 4, and the y-intercept is Negative five-halves

Step-by-step explanation:

we have

[tex]8x-2y=5[/tex]

This is the equation of the line in standard form

Convert the equation in slope intercept form

[tex]y=mx+b[/tex]

where

m is the slope

b is the y-intercept

Isolate the variable y

Subtract 8x both sides

[tex]-2y=-8x+5[/tex]

Divide by -2 both sides

[tex]y=4x-\frac{5}{2}[/tex]

therefore

[tex]m=4\\b=-\frac{5}{2}[/tex]

The slope is 4, and the y-intercept is Negative five-halves

Given that,

Based on the above information, the calculation is as follows:

8x - 2y = 5

We know that y = mx + b

Here  

m is the slope

b is the y-intercept

Isolate the variable y

So,

-2y = -8x + 5

Now divide 2 by both sides

[tex]y = 4x - \frac{5}{2}[/tex]

So,

m = 4

And b [tex]= \frac{-5}{2}[/tex]

Answer: 0.1359

Step-by-step explanation:

mean = $400

Standard deviation = $50

Since the wages is normally distributed , the first thing is to find the z - score.

z = [tex]\frac{x-mean}{standard deviation}[/tex]

finding the z - value for 300 and 350 , we have

z = [tex]\frac{300-400}{50}[/tex]

z = [tex]\frac{-100}{50}[/tex]

2 = -2

also

z = [tex]\frac{350-400}{50}[/tex]

z = [tex]\frac{-50}{50}[/tex]

z = -1

The next thing is to check the calculated value on z - table.

From z - table :

P (z[tex]\leq[/tex] -2 ) = 0.0228

P ( z [tex]\leq -1[/tex] ) = 0.1587

combining the two

P ( -2[tex]\leq[/tex]z[tex]\leq[/tex]-1 ) = 0.1587 - 0.0228

P ( -2[tex]\leq[/tex]z[tex]\leq[/tex]-1 ) = 0.1359

Therefore , the the probability that a worker

selected at random makes between

$300 and $350 = 0.1359
