Answer:

18.75

Step-by-step explanation:

80 = 100%

1% = 100%/100 = 80/100 = 0.8

the grades changed by 95 - 80 = 15.

how many % is that ?

we find the answer by checking how often 1% fits into 15. and we do this kind of check by division :

15 / 0.8 = 18.75

so, the grades changed by 18.75%.

Step-by-step explanation:

It will take 2 seconds a jet to accelerate from 200 m/s to 300 m/s with a constant acceleration of 50 m/s.

One type of operation in mathematics is division. We divide the phrases or numbers into the same number of components during this operation.

Given:

A constant acceleration is of 50 meter per second.

A jet to accelerate from 200 m/s to 300 m/s.

Acceleration is 100 meters per 2 seconds.

That means,

it will take = (300 - 200)/ 50 m/s

                = 2 seconds.

Therefore, it will take 2 seconds.

Step-by-step explanation:

no, it does not.

because almost every valid value of x (from -3 to +3) has 2 associated result values of y.

like x = 0 has y = 3 and y = -3.

but for a function there can be only ONE associated y value for every valid x value.

If the length of a tennis court is (7x + 8) ft, and its width is (3x + 6) ft, the expression of that represents the area of the court is: [tex]\mathbf{Area = 21x^2 + 66x + 48}[/tex]

Recall:

Given the algebraic expressions for the dimension of the rectangular court as:

length = (7x + 8) ft

width = (3x + 6) ft

Area = [tex](7x + 8) \times (3x + 6)[/tex]

[tex]Area =7x(3x + 6) +8(3x + 6)\\\\Area = 21x^2 + 42x + 24x + 48\\\\[/tex]

If the flight back to Boston against the same wind took 6 hours. The speed of the wind if the speed of the plane in still air is 550 mph is 50 mph.

Given data:

Boston to London = 5 hours

Flight back to Boston  = 6 hours

Still air = 550 mph

Using this formula

Speed (s) = Distance /Time

We need to formula an equation that will be used to find the speed

Equation: (550 + s)5 = (550 - s)6

So,

Let s represent the speed

(550 + s)5 = (550 - s)6

2750 +5s = 3300 - 6s

Collect like terms

6s +5s = 3300 - 2750

11s = 3300 - 2750

11s = 550

Divide both side by  11s

s= 550/11

s = 50mph

Therefore the speed of the plane is 50mph.

Answer:

y=6x+11

Step-by-step explanation:

The slope of y=3x+4 is 3 and the slope of y=6x+11 is 6.

Hope this helps :)

y = 3x + 4 is the steeper line with the slope 3

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The given two lines are y = 3x + 4 and y = 6x + 11

In the given line  y = 3x + 4

The slope of the line is 3

In the given line  y = 6x + 11

The slope of the line is 6

Among the two lines the line y = 3x + 4 has less slope. So the  the steeper line y = 3x + 4

Hence, y = 3x + 4 is the steeper line with the slope 3

A checking account

Step-by-step explanation:

It's called a checking account

Answer:

i have no idea what this question is asking for but my guest is that you need to reformate the equations

-5x+y=-11 in y+mx+b format is y=5x-11

x-y=7 in y=mx+b formate is y=-x+7

Step-by-step explanation:

you know what the slope of the line is ? it is the inclination of the line. how strongly is it going up or down, or is it maybe flat ?

in the formulas the slope is always the factor of x. the slope is excised as ratio of y coordinate change / x coordinate change when going from one point to another.

we see here 2 clear points in my opinion :

(0, -3) and (3, 0)

that is where the line crosses the y and the coordinate axis.

so, going from (0, -3) to (3, 0) :

x changes by +3 (from 0 to 3)

y changes by +3 (from -3 to 0).

so, the slope is

+3/+3 = 1

Answer:

The most she can spend on each blank shirt is $5.50.

Step-by-step explanation:

In order to set up the inequality, we need to write an expression for the total cost of each shirt wherein the price of each blank shirt is "x". Tina needs to buy 12 shirts and there is an additional charge of $2.75 for each logo. The total cost needs to be less than or equal to $99.

This gives us 12 * (x + 2.75) ≤ 99

We can then distribute:

12x + 12 * 2.75 ≤ 99

12x + 33 ≤ 99

Then subtract 33 from both sides:

12x ≤ 66

And finally divide by 12 on both sides:

x ≤ 5.5

Answer:

Step-by-step explanation:

12x + 2.75*12 < 99             Combine 12 * 2.75

12x + 33 < 99                     Subtract 33 from both sides

12x < 99 - 33                      Combine

12x <66                               Dive by 12

x < 66/12

x < 5.50

The very most she can spend is 5.50 on each shirt. Actually it should be 5.49 which will be less than 99. It will come to 65.88 which is just 12 cents less than 99, but it answers the problem. The problem does not use less than or equal which would mean that 99 is the answer ≤
