5x+34+8x+15=88

step by step

Let's solve your equation step-by-step.

5x+34+8x+15=88

Step 1: Simplify both sides of the equation.

5x+34+8x+15=88

(5x+8x)+(34+15)=88(Combine Like Terms)

13x+49=88

13x+49=88

Step 2: Subtract 49 from both sides.

The volume of a cylinder is 576Pi cubic inches. The radius of the circular base is 4 inches. What is the height of the cylinder?

Recall the formula V = pi r squared h.
18 inches
24 inches
36 inches
72 inches

Answers

Answer:

The height of the cylinder is 36 inches

Step-by-step explanation:

Given, The volume of a cylinder is 576[tex]\pi[/tex] cubic inches and the radius is 4 inches.

[tex]\pi[/tex] = 3.14

Formula for voulme of cylinder is V = [tex]\pi[/tex] * r^2 * h

Substitute the given values in the above formula to find the unknown value.

V = 3.14 * 4^2 * h

576[tex]\pi[/tex] = 3.14 * 4^2 * h

1,808.64 = 3.14 * 16 * h

1,808.64 = 50.24 * h

1,808.64 / 50.24 = h

36 = h

h = 36 inches

The final answer is 36 inches.

Therefore the height of the cylinder is 36 inches.

Answers

Answer: The area of the banner is 100 in^2

Step-by-step explanation:

so let say the banner was still a rectangle with the triangle still  attached to it so if we needed to find the area of the whole rectangle we will need to multiply the length times the width

so  14 * 8 =  112    

But now a triangle is being cut out of the rectangle so we need to find the area of the triangle being cut out and subtract it from the area of the whole rectangle.  But first we need to find the base and the base is 8  since the other side  base is 8  too and the height will be 3 since 14- 11= 3  

Now find the area of the triangle by multiplying the base times the height and divide it by 2.

8 * 3= 24

24/2= 12

subtract 12 from 112

112- 12 = 100

Step-by-step explanation:

You have to guve the probabiloty of picking a candy that is not blue, so you have to do:

5 red + 4 green = 9

total = 5 + 4 + 3 = 12

9/12 is equal to 3/4

Step-by-step explanation: the  answer is3/12

it is 3/12 because if you add 5+4+3 you will get 12 so out of that 12 which are blue which is 3 so it would be three

An aircraft carrier left Port 35 traveling north five hours before a container ship. The container ship traveled in the opposite direction going 8 km/h faster than the aircraft carrier for seven hours after which time the ships were 303 km apart. What was the aircraft carrier's speed ?

Answers

Answer:

Aircraft carrier speed = 4.97 km/h

Step-by-step explanation:

Given that the time taken by the aircraft = 5 hours

Let the distance covered = X

Speed = V

Time taken by the ship = 7 hours

Let the distance covered = Y

Speed = 8V

Since it is 8 km/h faster than the aircraft carrier.

Using the speed formula

Speed = distance/time

Distance = speed × time

For the aircraft;

X = 5V

For the ship:

Y = 7 × 8V = 56V

Since they are 303km distance apart,

X + Y = 303

5V + 56V = 303

61V = 303

V = 303/61

V = 4.97 km/h

Aircraft carrier speed = 4.97 km/h

Check all of the points that are solutions to the system of inequalities.
Y=>5x-3
X<5
