Vincent has already finished 5 oil changes today, and can complete more at a rate of 1 oil change per hour. Warren just came on shift, and can finish 2 oil changes every hour. Sometime during the day, the friends will be tied, with the same number of oil changes completed. How long will that take? How many oil changes will Vincent and Warren each have done?

Answer:

B. 13

First, use the Pythagorean Theorem

a^2 + b^2 = c^2

5^2 + 12^2 = c^2

25+144=c^2

169=c^2

square root of 169=13

Therefore your answer would be, B. 13

Answer:

sq rt of 32 units

Step-by-step explanation:

use the pythagorean theorem:

4^2 + 4^2 = c^2

16 + 16 = c^2

32 = c^2

sq rt of 32 = c

The length of the hypotenuse of a right triangle is 4√2.

The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

Given:

P= 4 units, B= 4 units

Now, using Pythagoras theorem

H² = P² + B²

H² = 4² + 4²

H²= 16+ 16

H² =32

H= √32

H= 4√2

Hence, the Hypotenuse is 4√2.

Given :

The store sells gasoline for .25 per gallon below it's regular cost per gallon.

Suppose the store sells 5,750 gallons that day.

To Find :

the stores profit or loss in comparison to the amount the store would had made without the special offer.

Solution :

Since, store is selling gasoline for lower amount than regular so they will be in loss.

Loss =$ 0.25 × 5750

Loss = $1437.5

Therefore, loss of store in comparison to the amount the store would had made without the special offer is $1437.5 .

Hence, this is the required solution.

WE know, compound interest is given by :

[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]

Here, P is principle amount.

r is annual interest rate.

n, number of times that interest is compounded per unit t .

t, time the money is invested or borrowed for.

To Find :

How much more money would Isabella have in her account than Gabriel, to the nearest dollar.

Solution :

[tex]D = P(1 + \frac{r_1}{n})^{nt}- P(1 + \frac{r_2}{n})^{nt}\\\\D = 77000\times ( 1 + \dfrac{33}{8\times 12})^{12\times 6}-77000\times ( 1 + \dfrac{7}{2\times 12})^{12\times 6}\\\\D = \$(1.257\times 10^{14})[/tex]

Answer: 3534

3534 in delta math

Step-by-step explanation:

Answer:

5

Step-by-step explanation:

Let x be the number of cell phones with keyboards needed.

40% = [tex]\frac{40}{100}[/tex]

[tex]\frac{x+45}{x+120}[/tex] = [tex]\frac{40}{100}[/tex]

x+45 = 40 -----1

x+120 = 100 -----2

You would want to make the total of 1 the same as 2.

1×[tex]\frac{100}{40}[/tex]: 2.5+112.5 = 100 -----3

Now 2 and 3 are equal.

x+120 = 2.5x+112.5

Isolate the x and numbers.

120-112.5 = 2.5x-x

Simplify.

1.5x = 7.5

x = [tex]\frac{1}{1.5}[/tex] × 7.5

x = 5

The manager of the store needs to add 5 more cell phones with keyboards.

Step-by-step explanation:

4(2x - 1) = 3x + 6

Simplify

8x - 4 = 3x + 6

Subtract 3x from both sides

8x - 3x - 4 = 3x - 3x + 6

5x - 4 = 6

Add 4 to both sides

5x - 4 + 4 = 6 + 4

5x = 10

Divide both sides by 5

5x/5 = 10/5

x = 2

Step-by-step explanation:

4(2x - 1) = 3x + 6

8x-4=3x+6

8x-3x=6+4

5x=10

x=10/5=2

Answer:

[tex]6\frac{2}{3}[/tex] %

Step-by-step explanation:

First, convert 3 meters into centimeters.

1m = 100cm

3m = 100 × 3 = 300cm

Now, form the fraction by putting the given value, 20cm, over the total measurement, 300cm.

[tex]\frac{20}{300}[/tex] = [tex]\frac{2}{30}[/tex] = [tex]\frac{1}{15}[/tex]  ⇒ Simplify your fraction to its simplest terms.

Next, multiply your simplified fraction by 100 to get your percentage.

[tex]\frac{1}{15}[/tex] × [tex]100[/tex] = [tex]\frac{100}{15}[/tex] = [tex]6\frac{10}{15}[/tex] = [tex]6\frac{2}{3}[/tex] %   ⇒ Simplify your percentage to its simplest terms.

Larry's statement is correct

Step-by-step explanation:

Larry says 5 × 900 is less than 5 × 9,000.

Doni says 5 × 900 is greater than 5 × 9,000.

5 × 900 = 4500

5 × 9000 = 45,000

45,000 is greater than 4500 because the place value of 45,000 is tens thousands and 4500 is Thousands.

Hence, Larry's statement is correct.(Larry says 5 × 900 is less than 5 × 9,000.)

j=3+25, here's the equation

Step-by-step explanation:

J=28

Answer:

j = 28

Step-by-step explanation:

Since we know that j is 25 more than 3, then we must know that 3+25= J (because J is 25 more/+ than 3) So, we simply solve 25+3 which equals 28.

The new point after rotation of point  (-7, -3) counterclockwise by 90 degrees will be ( 3, -7).

A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).

Coordinates are always written in the form of small brackets the first term will be x and the second term will be y.

For example (5,3) here 5 will be for the x and 3 will be for the y.

Another example is (9,0) here 9 is for x and 0 is for y.

Given,

Point A =  (-7, -3)

Let's say after rotation this point moves to a new coordinate (x, y) which is point B

Let's say the origin is O

Slope of line segment AO = (-3-0)/(-7-0) = 3/7

Slope of line segment BO = (y - 0)/(x - 0) = y/x

Now,

Since both lines are perpendicular to each other so

Slope AO × Slope BO = -1

3/7 × y/x = -1 ⇒ 3y = -7x

Now if we observe the result then it will be clear that if we put x = 3 than y = -7 will be the new coordinate.

Hence, The new point after rotation of point  (-7, -3) counterclockwise by 90 degrees will be ( 3, -7).
