PLEASEEE SOMONEE HELP ASAP!! If The Pattern Shown Continues How Many Black Keys Appear On A Keyboard

Answers

Answer 1

Answer:

25 black keys

Step-by-step explanation:

Let the number of requires black keys = 'x'

White key : Black keys = 7 : 5

7 : 5  :: 35 : x

Product of extremes = product of means

             7 *x = 35 * 5

                  x = [tex]\frac{35*5}{7}[/tex]

                 x = 5 *5

                 x = 25

Give your answer as an improper fraction in its simplest form.​

Answers

Answer:

y = - [tex]\frac{72}{5}[/tex]

Step-by-step explanation:

Plug x = -6 into the given equation : 8(-6)−5y=24Multiply the numbers: -48 - 5y = 24Move the constant to the right-hand side and change its sign: -5y = 24 +48Add the numbers: -5y = 72Divied both sides of the equation by -5 : y = - [tex]\frac{72}{5}[/tex]

The math club is having a car wash to raise funds to attend a state competition. They need to raise a minimum of $325.00. The cost of supplies for the car wash is $25.00. If they expect 40 cars on the day of the car wash, what is the amount they will have to charge each car to meet the minimum goal?

Answers

Answer:

8.75

Step-by-step explanation:

the formula to use would be:

$325 = 40x - 25

add 25 to both sides of the equation to get:

$350 = 40x

divide both sides by 40 to get:

x = 350/40 = $8.75

if they charge $8.75 per car, they will raise 40 * that for a total of $350.

they would then subtract the $25 for the cost of the supplies and they would be left with $325.

that's their minimum goal.

Answer:

7x - 8y = -23

Slope = 1.750/2.000 = 0.875

x - intercept = -23/7 = 3.28571

y - intercept = 23/8 = 2.87500

7x - 7y = -14

Slope = 1

x - intercept = -2/1 = -2.00000

Answer:

n= 1.8

Step-by-step explanation:

Solve the following expression:

n/-15 = -1.2

(-1.5) n/-1.5 = -1.2(-1.5)

n=1.8

Therefore, the final answer is n = 1.8.

Submit Answer

Answers

Answer:

[tex] TV = 34 [/tex]

Step-by-step explanation:

WX = 23 – 2x,

TV = 64 – 10x,

First, create an equation you will use to find the value of x.

Thus:

[tex] WX = \frac{1}{2}(TV) [/tex] (midsegment theorem of a ∆)

[tex] 23 - 2x = \frac{1}{2}(64 - 10x) [/tex] (substitution)

[tex] 23 - 2x = \frac{1}{2}(64 - 10x) [/tex]

Multiply both sides by 2

[tex] (23 - 2x)*2 = \frac{1}{2}(64 - 10x)*2 [/tex]

[tex] 46 - 4x = 64 - 10x [/tex]

Collect like terms

[tex] 46 - 64= 4x - 10x [/tex]

[tex] -18= -6x [/tex]

Divide both sides by -6

[tex] 3 = x [/tex]

[tex] x = 3 [/tex]

Find TV:

[tex] TV = 64 - 10x [/tex]

Plug in the value of x

[tex] TV = 64 - 10(3) = 64 - 30 [/tex]

[tex] TV = 34 [/tex]

A cheetah runs at an average speed of 50 mph between two jungles that are 150 miles apart. An antelope runs at an average speed of 30 mph, a lion runs at an average speed of 25 mph, and an elephant runs at an average speed of 15 mph.
How long does it take each animal to run to the second jungle?

Answers

Answer:

cheetah, 3 hours antelope, 5 lion, 6 elephant, 10

Step-by-step explanation:

The time taken by each animal to reach another jungle are:

Cheetah = 3 hours

Antelope = 5 hours

Lion = 6 hours

Elephant = 10 hours

What is speed?

Speed is a scalar quantity that refers to how fast an object is moving.

Given are the speeds of different animals,

Cheetah = 50 mph

Antelope = 30 mph

Lion = 25 mph

Elephant = 15 mph

Speed = distance/time.

Time = distance/speed

Distance = 150 miles

Time taken by each :

Cheetah = 150/50 = 3 hours

Antelope = 150/30 = 5 hours

Lion = 150/25 = 6 hours

Elephant = 150/15 = 10 hours

Hence, The time taken by each animal to reach another jungle are:

Cheetah = 3 hours

Antelope = 5 hours

Lion = 6 hours

Elephant = 10 hours

Given the following two equations determine if they are parallel, perpendicular, or neither.
3x + 6y = 30
4y + 2x = 9

Please show work!

Answers

Answer:

Parallel

Step-by-step explanation:

What you want to do first is to put both equations into the slope intercept form: y=mx+b.

In the first equation, you move the [tex]3x[/tex] to the right side of the equal sign by subtracting on both sides:

[tex]6y = -3x + 30[/tex]

Then you want to divide both sides by 6 to isolate y:

[tex]y = -\frac{1}{2}x + 5[/tex]

Next for the second equation, you do similar steps. You subtract [tex]2x[/tex] from both sides:

[tex]4y=-2x+9[/tex]

Then you want to divide both sides by '4' to isolate y:

[tex]y= -\frac{1}{2}x+\frac{9}{4}[/tex]

Now to check if the two equations are parallel, perpendicular, or neither, you compare the slopes 'm' which is the coefficient next 'x'. If two equations have the same slope, then they are parallel. If the slopes multiplied equal -1, then they are perpendicular. If the slopes are not the same or if the product of the slopes is not -1, then it is neither.

In the case of this problem, the slopes are the same, so the equations are parallel:

[tex]-\frac{1}{2} = -\frac{1}{2}[/tex]
