Answer: $37.20

Step-by-step explanation:

24.50+12.70=37.20

Quinn earned a total amount of $37.20 which is the addition of the earnings from dog-sitting and the recycling cans.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

We have been given that Quinn earned $24.50 for dog-sitting and $12.70 for recycling cans.

We have to determine the total amount he earned.

The total amount is the addition of the earnings from dog-sitting and the recycling cans.

The total amount = earnings from dog-sitting + earnings from the recycling cans.

The total amount = $24.50 + $12.70

The total amount = $37.20

Therefore, he earned a total amount of $37.20.

So yes u is -1

Answer:

$63.55

Step-by-step explanation:

Taxes are charges paid by individuals and enforced by the government in other to fund government spending and various public expenditures.

The flowers cost $59.95 and tax is 6%.

Tax = 6% of flower cost = 0.06 × $59.95 = $3.6

The  total cost of the flowers is the sum of tax and the cost of flowers, hence:

Total cost of the flowers = $59.95 + $3.6

Total cost of the flowers = $63.55

Answer:

7 pieces of candy each friends have

Step-by-step explanation:

35 ÷ 5 = 7

5 × 7 = 35

so the answer is 7

Each friend will receive 7 pieces of candy after dividing it equally.

" Division is the method of distributing or sharing any group of items equally."

According to the question,

Total pieces of candy = 35

Total number of friends= 5

Division of candy between 5 friends

Number of candy each friend will received = 35 ÷ 5

                                                                        = 7pieces

Hence, Each friend will receive 7 pieces of candy.

Answer: 60%

Step-by-step explanation:

Given: Climbing rate at the end of week 1 = 25 steps per minute.

Climbing rate at the end of week 4 =   60 steps per minute

The  percent increase in Maggie's rate of climbing steps from the end of week 1 to the end of week 4 will be :

[tex]\dfrac{\text{Climbing rate after week 4 - Climbing rate after of week 1}}{\text{Climbing rate after week 1}}\times100[/tex]

[tex]=\dfrac{40-25}{25}\times100\\\\=\dfrac{15}{25}\times100=15\times4=60\%[/tex]

Hence, the percent increase in Maggie's rate of climbing steps from the end of week 1 to the end of week 4 = 60%

Answer:

2/3

Step-by-step explanation:

I think you meant y=2/3x+4 because what you wrote the correct equation for slope, but anyway the slope would be 2/3 because if lines are parallel, they have the same slope.

I hope this helps!

Answer:

Slope = -1

Step-by-step explanation:

[tex](3, -5 ) = (x_1,y_1) \\ (-7,5)=(x_2,y_2)[/tex]

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

Substitute values into the given equation

[tex]slope \: = \frac{5 - ( - 5)}{ - 7 - 3} \\ \\ slope \: = \frac{5 + 5}{ - 7 - 3} \\ \\ [/tex]

[tex]slope \: = \frac{10}{ - 10} \\ slope \: = - 1[/tex]

Answer:

To get 2 imaginary solutions, c must be less than -2

Step-by-step explanation:

The general form of the quadratic equation is:

[tex]ax^2+bx+c=0[/tex]

Solve the quadratic equation by using the formula:

[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

The equation to solve is:

[tex]-2x^2+4x+c=0[/tex]

In our equation: a=-2, b=4, c=unknown

For the roots to be imaginary, the argument of the square root must be negative, that is:

[tex]b^2-4ac<0[/tex]

Substituting the known values:

[tex]4^2-4(-2)c<0[/tex]

[tex]16+8c<0[/tex]

Subtracting 16:

[tex]8c<-16[/tex]

Solving:

[tex]c<-2[/tex]

Thus, to get 2 imaginary solutions, c must be less than -2

Answer:

C. Sin 75,5 = y/12

Step-by-step explanation:

This angle can be calculated using the law of sine:

sin(angle)=opposite cathete/hypothenuse

sin(angle)=wall/ladder

In this exercise we want to calculate the height of the ladder, so the equation is changed afterwards.

sin(angle)=wall/ladder

sin(75,5°)=12ft/y

The height y above the ground in feet is ; (C ) sin 75.5 = y / 12

The ladder, the horizontal ground and the vertical height above the ground form a right angle triangle are ;

The vertical height y = opposite

Length of ladder = hypotenuse

Horizontal ground  = adjacent.

According to trigonometry, sine of an angle is opposite/hypotenuse

sin 75.5 = y/12.

In conclusion, the height y above the ground in feet is sin 75.5 = y / 12.

Answer:

D. b = r+z

Step-by-step explanation:

Given the expression b-r = z, we are to solve for b. To do this, we will add 'r' to both sides of the equation as shown;

b-r+r = z+r

Since -r+r = 0, substitute:

b+0 = z+r

b = z+r

Hence the resulting equation when r is added to both sides of the equation is b = z+r

Hence option D is correct

Answer:

A. 1 mile / 1,760 yards

Step-by-step explanation:

A single conversion factor is a number that we can multiply directly with 8,462 yards to determine how many yards are there in 8,462 yards.

Since 1 mile is to 1,760 yards, the single conversion factor to use in determining how many miles a number of yards would be = 1 mile/1,760 yards = [tex] \frac{1}{1,760} [/tex]

Thus, to find out many miles are in 8,462 yards, multiply by [tex] \frac{1}{1,760} [/tex].

[tex] 8,462*\frac{1}{1,760} = \frac{8,462}{1,760} = 4.8 [/tex] miles

Answer:

The answer is below

Step-by-step explanation:

Let x represent the cost of apples, y represent the cost of strawberries and z represent the cost of oranges.

The money used to buy 2 apples, 3 boxes of strawberry, and 4 oranges is represented as:

2x + 3y + 4z = 15.3         (1)

The money used to buy 4 apples, 1 boxes of strawberry, and 2 oranges is represented as:

4x + y + 2z = 10.9       (2)

The money used to buy 5 apples, 2 boxes of strawberry, and 1 oranges is represented as:

5x + 2y + z = 13.7        (3)

Solving equation 1, 2 and 3 simultaneously gives:

x = $1.5, y = $2.5 and y = $1.2

The cost of orange is $1.5, cost of strawberry = $2.5 and cost of orange = $1.2

Answer:

B 50=n(125) 40%

Step-by-step explanation:

The percent equation, 125 = n(50); 250%

A number or ratio which can be expressed as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage therefore refers to a part per hundred. Per 100 is what the word percent means. The letter "%" stands for it. There is no dimension to percentages. As a result, it is known as a dimensionless number. When we say a number is 50% of something, we mean that it is 50% of everything.

As in 0.6%, 0.25%, etc., percentages can also be expressed as decimals or fractions. The grades earned in any subject have been calculated in terms of percentages in academics.

Let the required percentage be x%.

A/c to question,

[tex]\frac{x}{100} * 50= 125\\\\ x=250[/tex]

That is, required percentage is 250%.

Hence, option C is correct.
