Answer:

Value of miles traveled (m) = 13 mile

Step-by-step explanation:

Given:

Equation

3.00 + 0.50 m = 9.50

Find:

Value of miles traveled (m)

Computation:

3.00 + 0.50 m = 9.50

0.50 m = 9.50 - 3.00

0.50 m = 6.50

m = 6.50 / 0.50

m = 13

Value of miles traveled (m) = 13 mile

Answer:

The question is not complete, below is the complete question:

A taxi driver wrote a formula to represent the mileage and fee for his last customer. He wrote the equation 3.00 + 0.50 m = 9.50, where m represents the number of miles traveled.

Which statement shows the meaning of the driver's equation? Check all that apply.

a.) Three dollars added to $0.50 is the same as $9.50.

b.) Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.

c.) Three dollars more than the quotient of $0.50 and the number of miles is nine dollars and fifty cents.  

d.) The product of the number of miles and the sum of $3 and $0.50 is equal to $9.50.

e.) The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.

Answers

The correct answers are:

b

e.) The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.

Step-by-step explanation:

The formula written by the driver is: 3.00 + 0.50 m = 9.50

where m = number of miles travelled

This means that when the product of 0.50 and the number of miles travelled 'm' is added to $3, the result is 9.50

And this is the same explanation as the following options:

a.) Three dollars($3) plus $0.50 times the number of miles is equal to nine dollars and fifty cents($9.50).

e.) e.) The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents;

note that 50 cents is the same as $0.50

Answer:

230 capsules.

Step-by-step explanation:

The following data were obtained from the question:

Taste >>>>>>>>>>> Frequency

Volluto >>>>>>>>>> 12

Livanto >>>>>>>>>> 7

Ristretto >>>>>>>>> 23

Cosi >>>>>>>>>>>> 3

Other >>>>>>>>>>> 5

Next, we shall determine the total frequency.

This is illustrated below:

Total frequency = 12 + 7 + 23 + 3 + 5

Total frequency = 50

Finally, we shall determine the number of Ristretto in 500 capsules.

This can be obtained as follow:

Number of Ristretto = Frequency of Ristretto /total frequency x total capsule

Frequency of Ristretto = 23

Total frequency = 50

Total capsule = 500

Number of Ristretto = 23/50 x 500

Number of Ristretto = 23 x 10

Number of Ristretto = 230.

Therefore, the number of Ristretto in the 500 capsules is 230.

Answer:

Step-by-step explanation:

coordinate of O(2,1),Y(3,-2),T(-3,-3)

let the reflected points are O',Y',T'

distance of O from y=2 is 1 unit.

∴ ordinate of O' =1+2(1)=3

or O' is (2,3)

distance of Y from y=2 is2+2=4

ordinate of Y'=-2+2(4)=6

so coordinate of Y' is (3,6)

distance of T from y=2 is (2+3)=5

so ordinate of T' =-3+2(5)=7

coordinate of T' is(-3,7)

Answer:

Answer:

The output is 5

Step-by-step explanation:

y=x+2,

Let x =3

y = 3+2

y = 5

The output is 5

Answer:

5

Step-by-step explanation:

We are given the relation:

y=x+2

The input is also called "x", and the output is also known as "y". We want to find the output, or y, when x is equal to 3.

Therefore, we must substitute 3 in for x and solve.

y= x+2 at x=3

y=3+2

Add 3 and 2.

y=5

If the relation is y=x+2 and the input is 3, then the output is 5.

After raising the walls of the building of height 2cm 5 times the height of the wall will be 10cms.

Multiplication is a short hand of addition like if we have to add 2 by100  times it is same as multiplying 2 with 100 which is 200.

According to the given question Bryce is making a model building.

Said that he raises the walls of the building by 2 centimeters five times.

So, Either we can sum 2 centimeters 5 times which is (2 + 2 + 2 + 2 + 2) which is

= 10cms.

Or we can multiply the height of the building which is 2 cm by the no. of times he raised it which is 5.

∴(2×5) = 10cms.

Answer:

The correct unit price can be calculated by dividing the total price paid by 84 that was the number of pairs of padded work gloves that were bought:

$102.48/84=$1.22

The correct unit price is $1.22.

-The error is that the person calculated the unit price by dividing the total price paid by 7 but the statement indicates that the contractor purchased 7 dozen pairs, which means: 7*12= 84. According to this, the contractor purchased 84 pairs of padded work gloves.

Answer:

Step-by-step explanation:

Given initial population of animals = 300 animals

If the population increases by 23% annualy, yearly increment will be expressed as:

Yearly increment = 23% of 300

Yearly increment = 0.23*300

Yearly increment for = 69

Let the total number of years of be x

Increment after x years = 69x

Increase in population of animals after x years with an annual rate of 23% = Initial population + Increment after x years

= 300 + 69x

Hence, the equation represents a population of 300 animals at the increase and an annual rate of 23% is expressed as 300 + 69x

Answer:

Given equation: [tex]x^2 = -8x -7[/tex]

To solve the quadratic equation, we will need to set one side of the equation equal to 0. This can be done by subtracting x² on both sides.

[tex]\implies x^2 - x^2= -8x -7 - x^2[/tex]

[tex]\implies 0= -8x -7 - x^2[/tex]

To further simplify, we can factor -1 from the expression on the R.H.S. Then, we can cancel the -1 since there is a 0 on the other side.

[tex]\implies 0= -1(8x + 7 + x^2)[/tex]

[tex]\implies 0= 8x + 7 + x^2 = x^2 + 8x + 7[/tex]

Finally, factor the expression on the right hand side.

Factoring a quadratic equation can be done in 2 ways.

In this method, we split the middle term into two suitable terms. The suitable terms must follow two conditions.

Then, we factor the first two terms of the expression and the last two terms of the expression. Eventually, we will get a common expression. So, we can further factorize to get a product of two expressions.

In this method, we will compare our equation with the standard form equation to determine the a, b, and c variables. Then, we plug the variables into the formula and simplify to get the roots (solutions).

[tex]\text{Quadratic Formula:} \ \dfrac{-b\ \± \sqrt{b^{2} - 4ac} }{2a}[/tex]

We can use any method to solve for the roots. First, let us check whether the middle term could be split into two suitable terms such that those terms could meet the criteria stated above.

-----------------------------------------------------------------------------------------------------

We can see that 8x is the middle term and it can be split into the sum of 7x and x. The product of the (middle term) coefficients is 7. The product of the coefficients (first and last terms) is also 7. Since both products match, we can use the splitting method to factorize the expression.

[tex]\implies 0= x^2 + 8x+ 7[/tex]

[tex]\implies 0= x^2 + x + 7x+ 7[/tex]

Now, factor the first two terms and the last two terms separately.

[tex]\implies 0= x^2 + x + 7x+ 7[/tex]

[tex]\implies 0= x(x + 1) + 7(x+ 1)[/tex]

We can see a common expression. Finally, let us factor the common expression to get a product of two expressions.

[tex]\implies 0= (x + 7)(x + 1)[/tex]

Since the factorized expression equals to 0, we can set each expression (inside the parentheses) equal to 0.

[tex]\implies x + 7 = 0; x + 1 = 0[/tex]

[tex]\implies x = -7; x = -1[/tex]

Now, let us try to solve using the Quadratic formula.

[tex]0= x^2 + 8x+ 7[/tex]

Tip: Standard form: 0 = ax² + bx + c

Comparing both equations will allow us to determine the a, b, c variables.

⇒ a = 1; b = 8; c = 7

Now, let us plug these values into the quadratic formula and simplify.

[tex]\implies \dfrac{-b\ \± \sqrt{b^{2} - 4ac} }{2a}[/tex]

[tex]\implies \dfrac{-8\ \± \sqrt{8^{2} - 4(1)(7)} }{2(1)}[/tex]

[tex]\implies \dfrac{-8\ \± \sqrt{64 - 28} }{2}[/tex]

[tex]\implies \dfrac{-8\ \± \sqrt{36}}{2} = \dfrac{-8\± 6}{2} = \dfrac{-8 + 6}{2},\ \dfrac{-8 - 6}{2} = \dfrac{-2}{2} ,\ \dfrac{-14}{2} = -1 , -7 \ \text{(B)}[/tex]

Therefore, in both methods, the answer is -1, -7 (B).

[tex]= -4\left(2x-y\right)+y+5\left(x+y\right)[/tex]

Open the parenthesis:

[tex]= -4(2x)-4(-y)+y+5(x)+5(y)\\\\= -8x+4y+y+5x+5y[/tex]

Collect the like terms:

[tex]= -8x+5x+4y+y+5y[/tex]
