Answer:20%

Step-by-step explanation:Based on the given conditions, formulate:( 35 - 28 ) divided by 35

Calculate the sum or difference: 7/ 35

Cross out the common factor: 1/5

Multiply a number to both the numerator and the denominator: 1/5 x 20/20

Write as a single fraction: 20/5x20

Calculate the product or quotient:20/100

The percent error of Hector’s guess will be 25%.

A relative number reflecting the hundredth part of any amount. One percent (symbolised 1%) is one hundredth part; consequently, 100 percent denotes the complete amount and 200 percent defines twice the supplied amount. percentage.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

Hector's prediction is 35 stuffed animals. There are a total of 28 stuffed animals.

The percent error is calculated as,

P = [(35 - 28) / 28] x 100

P = (7 / 25) x 100

P = 0.25 x 100

P = 25%

The percent error of Hector’s guess will be 25%.

So, from the question statement, we can conclude that the y and x axes are directly proportional. In order to  show it in the equation form, we can write,

Y=kx (directly proportional)

y=k x

The values that are given in the question are

y = 15

and,

x = 10

Now we will put these individual values in the above relation equation of x and y,

y=k x

15=10k

k=15/10

k=1.5

So, we found the unknown factor by putting the values of the available terms. Now in order to find the new value of y, when the new values of x are given and is,

x=22

We will simply modify the relation equation,

y=k x

By putting the known terms in the above equation,

x=22, k=1.5

y=1.5 * 22

y = 33.

b)6 months

Step-by-step explanation:

a) if he pays $6 every month then you would times $6 by 5 to find out how much he paid off which is 30 so you would add that to the current amount therefore $30+$32=$62

b) You would do $32 divided by 6 to find out how much hit would take to pay off which is 5 but there is 2 remaining so he can pay that off the next month, so it takes 6 months

Answer:

(10, -2)

Step-by-step explanation:

The inequalities are:

y < x - 7               (1)

y < (1/5)x - 2        (2)

To solve this problem, we have to solve both equations simultaneously and then find the value of x and y that makes the inequality true.

To solve the inequality, subtract inequality (2) from inequality (1) which gives:

0 < (4/5) x - 5

-(4/5)x < -5

Dividing both sides of the equation by -4/5 gives:

-(4/5)x / (-4/5) < -5/ (-4/5)

x > 6.25

Put x > 6.2 in inequality 1

y < 6.25 - 7

y < -0.75

The solution of the inequality is x > 6.25 and y < -0.75

From the list of option, the correct answer is (10, -2) since 10 > 6.25 and -2 < -0.75

f(0) +g(1) = 5 +4 =9

F(2) = -2 + 5 =3

Step-by-step explanation:

Given f(x) = -x + 5

      g(x) = 2 x + 2

Put x=0 in f(x) = -x +5

                f(0) = -0 +5 =5

             g(x) = 2 x + 2

Put x= 1

             g(1) = 2(1) +2

             g(1) = 4

f(0) +g(1) = 5 +4 =9

b) f(x) = -x +5

put x = 2

F(2) = -2 + 5 =3

\((2x - \frac{1}{3} ) - ( \frac{2}{x} + 1)\)

\(2x - \frac{1}{3} - \frac{2}{x} + 1\)

\((2x - \frac{2}{x} ) + ( - \frac{1}{3} + 1)\)

\( (\frac{2 {x}^{2} }{x} - \frac{2}{x} ) + ( \frac{ - 1}{3} + \frac{3}{3} )\)

\( \frac{2 {x}^{2} - 2 }{x} + \frac{ - 2}{3} \)

We want to write the given expression as a single fraction. We will get the fraction:

\(\frac{6*x^2 - 4*x - 6}{3*x}\)

So we start with the expression:

\((2*x - \frac{1}{3}) - (\frac{2}{x} + 1)\)

First, let's rewrite each of these parenthesis as fractions, we need to have the same denominator in all the terms, then in the first one we can multiply and divide by 3 (and in the second one we can do the same but with x) so we get:

\((\frac{3}{3} *2*x - \frac{1}{3}) - (\frac{2}{x} + 1*\frac{x}{x} )\\\\(\frac{6*x}{3} - \frac{1}{3}) - (\frac{2}{x} + \frac{x}{x} )\\\\\frac{6*x - 1}{3} - \frac{2 + x}{x}\)

Now we must multiply and divide the left term by x, and the right term by 3, so we get:

\(\frac{x}{x} \frac{6*x - 1}{3} - \frac{2 + x}{x}*\frac{3}{3} \\\\\frac{6*x^2 - x}{3*x} - \frac{6 + 3x}{3*x} = \frac{6*x^2 - x - 3x - 6}{3*x}\\\\\frac{6*x^2 - 4*x - 6}{3*x}\)

use slope formula

The equation of line passes through the points (4, 3) and (2, 7) will be;

⇒ y = - 2x + 11

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (4, 3) and (2, 7)

Now,

Since, The equation of line passes through the points (4, 3) and (2, 7)

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (7 - 3) / (2 - 4)

m = 4 / -2

m = - 2

Thus, The equation of line with slope - 2 is,

⇒ y - 3 = - 2 (x - 4)

⇒ y - 3 = - 2x + 8

⇒ y = - 2x + 11

Therefore, The equation of line passes through the points (4, 3) and

(2, 7) will be;

⇒ y = - 2x + 11

the dimensions of an NHL ice rink are 85 ft by 200 ft.

Let's assume that the width of the rink is x ft. Then the length of the rink is 30 ft longer than twice the width, which means the length is (2x+30) ft.

The perimeter of the rink is the sum of the lengths of all four sides, which is given as 570 ft. So we can write:

2(width + length) = 570

Substituting the expressions for width and length, we get:

2(x + 2x + 30) = 570

Simplifying and solving for x, we get:

6x + 60 = 570

6x = 510

x = 85

So the width of the rink is 85 ft, and the length is (2x+30) = 200 ft.

True. The base of the portion formula represents the whole or 100 percent. It is the total amount or quantity from which a portion is being taken. The portion formula is used to calculate a part or fraction of the whole.


In mathematics, when calculating a portion or fraction of a whole, we use the portion formula. The base of the portion formula represents the total amount or quantity, which is considered as the whole or 100 percent. The portion being calculated is then expressed as a fraction or percentage of this base.

For example, if we want to find 30% of a number, the number itself would be the base, representing the whole or 100%. We then calculate 30% of that number to determine the portion.

In summary, the base of the portion formula does indeed represent the whole or 100 percent, making the statement true.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be A

7⁸ / 7y = 7⁶
