If four times a number, added to 3 is divided by the number plus 2, the result is seven halves. Find the number.
The number is…

Answer:

$9450

Step-by-step explanation:

Answer:

A = $9,450.00

A = P + I where

P (principal) = $9,000.00

I (interest) = $450.00

Calculation Steps:

First, convert R as a percent to r as a decimal

r = R/100

r = 5/100

r = 0.05 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 9,000.00(1 + 0.05/1)(1)(1)

A = 9,000.00(1 + 0.05)(1)

A = $9,450.00

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $9,000.00 at a rate of 5% per year compounded 1 times per year over 1 years is $9,450.00.

Option A is accurate. The points were plotted with the coordinates (x, log) y), and they are (3, 2.097), (4, 2.796), and (5, 3.495).

Exponents can also be written as logarithms. The other number is equal to a logarithm with a number base. It's the exact inverse of the exponent function.

Answer:

13/40

Step-by-step explanation:

Rewrite a percentage as a decimal: [tex]\frac{32.5}{100}[/tex]

Convert decimals to integers: [tex]\frac{325}{100}[/tex]

Reduce the fraction: [tex]\frac{13}{40}[/tex]

Answer: [tex]\frac{13}{40}[/tex]

32.5% as a fraction in simplest form is 13/40.

Here we have to find fractional form of 35 percent

Since we knw that,

A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

To convert a percentage to a fraction,

we can simply write it as a fraction with a denominator of 100.

Then,

we simplify the resulting fraction to its simplest form.

For 32.5%,

we can write this as,

⇒ 32.5/100

Now, we can simplify this fraction by dividing both the numerator and denominator by their greatest common factor (GCF).

The GCF of 32.5 and 100 is 12.5,

so we can divide both by 12.5,

⇒ 32.5/100 = (32.5 ÷ 12.5) / (100 ÷ 12.5)

                   = 13/40

Therefore, 32.5% as a fraction in simplest form is 13/40.

To conduct a hypothesis test for the above situation. We define the null hypothesis and the alternative hypothesis.

The null hypothesis is the claim that the average commute time to downtown is 20 minutes while the alternative hypothesis is a contradiction of the null hypothesis which is that the average commute time to downtown is not 20 minutes.

i.e. H0: μ = 20 and H1:  μ ≠ 20.

x = 26,  [tex]\mu[/tex] = 20, [tex]\sigma[/tex] = 7 and n = 15 putting the values in the question we will get the z-score value.

The width of the model is 3.6 inches.

The figures with the same shape are said similar when the sides of both the figures are in proportion.

Sara has a model of length = 18inches.

The original ship has a length is 160 ft

The width of the original ship is 32 ft

The model is a scaled-down version of the original figure and so the length and width of the model will be in the same proportion as the original dimensions.

Let x represents the width of the model then,

160/18 = 32/x

x = 32 * 18 / 160

x= 3.6 inches.

Domain: All real numbers

Range: All real numbers

Answer:

B)  0.5

Step-by-step explanation:

The given formula is:

          Height = Constant * Width

You may now choose any point on the graph (the horizontal line represents a point for width, and the vertical line represents a point for height) and put it into the specified formula. Let's test the two supplied points (2, 1):

Now, 2 is on the horizontal line, so we put it in for width, and 1 is on the vertical line, so we plug that in for height. When we do it, we get:

1 = C * 2

(In the expression above we need to solve for C, and we can do that by dividing both sides by 2)

C= 1/2 = 0.5

So, the answer is 0.5 or option B.

The following cannot be expressed as a fraction or whole number.

Hence, the following value of x is irrational.

Answer:

C 12/48

Step-by-step explanation:

Original fraction:

x/y

The ratio of the numerator to the denominator is 1:4, so

x/y = 1/4

Cross multiply:

y = 4x

If three is added to the numerator and subtracted from the denominator, the new fraction reduces to one-third.

(x + 3)/(y - 3) = 1/3

Cross multiply:

3(x + 3) = 1(y - 3)

3x + 9 = y - 3

Above, we have y = 4x, so substitute 4x for y in the equation just above and solve for x.

3x + 9 = 4x - 3

12 = x

x = 12

y = 4(12) = 48

The original fraction is x/y = 12/48

Answer:

Last graph that slopes upwards from left to right and that has an y-intercept of -1

Step-by-step explanation:

let us pick some points!(you can chose any two)

when x =3 , y = 14 : helps us get points (3,14)

when x =1 , y = 4 : helps us get points (1,4)

so we find the gradient using the two points:

[tex]gradient \ =\frac{14-4}{3-1} =\frac{10}{2} \\[/tex]

we now use gradient 10/2 and point (1,4) to find the equation  of the line:

[tex]\frac{10}{2} =\frac{y-4}{x-1} \\2(y-4)=10(x-1)\\2y-8=10x-10\\2y=10x-10+8\\2y=10x-2\\y=5x-1[/tex]

from the equation of the line found we are able to find the y- intercept of the line is -1 and that the line has a positive gradient thus should slope upwards from left to right.

From the pictures you posted, we pick the last graph as it seem to slope upwards from left to right and has the line cutting y axis at around -1
