Water flows through pipe at a rate of 490 Milliliters every 6.5 hours express this rate of flow influence one's permanent round
likoan [24]

Answer:

To the nearest hundredth, the rate of flow will be 75.38 mm/hr

Step-by-step explanation:

Here in this case, we are to express the rate at which the water flow and round it up to the nearest hundredth.

We are told that water flows through the pipe at a rate of 490 mm every 6.5 hours.

Now, the rate will be 490/6.5 = 75.384615384615 mm/hr

Rounding this value to the nearest hundredth, we have 75.38 mm/hr

Brayden is working two summer jobs, making $18 per hour lifeguarding and making $9 per hour clearing tables. In a given week, he
spin [16.1K]

Answer:

2 hours.

Step-by-step explanation:

Money earned for 14 hours of life-guarding = 14*18 = $252.  If he worked another 5 hours  to make the maximum of 19 he would earn 252 + 5*9

= $297  but he wants to work a minimum of hours for  a minimum of 270.

Thus we have the inequality:

252 + 9x ≤ 270

9x  ≤  18

x  ≤ 2.

So the number of hours he must do clearing tables = 2.

frutty [35]

Answer:

Ball cannot be fit inside the box.

Step-by-step explanation:

Given:

Circumference of ball = 26 inches

Dimension of box = 8.25 in x 8.25 in x 8.5 in.

We need to find the whether ball gets fits inside the box.

First we will find the Diameter of ball.

Circumference of ball is given so we will find radius of the ball.

Circumference of the sphere is equal to 2 times π times radius.

framing in equation form we get;

2\pi \times r =26\\\\r= \frac{26}{2\pi}= 4.14\ in.

Now we will find the Diameter of the ball.

Diameter of ball is equal to 2 times radius.

framing in equation form we get;

Diameter of ball =  2\times 4.14 = 8.28\ in

Now given that two parallel sides of box has dimension which is 8.25 in.

Since Dimension of box is smaller than diameter of the ball.

Hence we can say that ball cannot be fit inside the box.

Tju [1.3M]

Answer:

Step-by-step explanation:

we can use y = mx + b

m = 5

y = 5x + b\\\\3 = 5(4) + b\\3 = 20 + b\\b = -17\\y = 5x - 17
