AB = 29

We can split the line into two parts and then we see the distance from -8 to 0 equals 8 (in mathematical language |-8| = 8). The distance from 0 to 21 is obviously 21. Therefore the total length equals the sum of the numbers above and is 21 + 8 = 29.

Kindly check explanation

Step-by-step explanation:

Equipment elevator Descent = 4 fts per Second

Miners elevator descent = 17 ft/sec

Please help calculate the surface area
brilliants [131]

Answer:

<u>SA = 189 cm^2</u>

Step-by-step explanation:

What you're going to want to do is calculate the surface area of each type of side (triangle or rectangle) then add them up accordingly!

Starting with triangles: area = 1/2 * l * h

So, in this scenario its (1/2) * 6 * 4 , or half of 24, which is 12 cm^2

Since we have two triangular sides, that totals to 24 cm^2.

Then the rectangular sides: area = l*h

so, 5*11 = 55 cm^2

We have three rectangular sides, totalling 165 cm^2

165+24 = 189 cm^2

Jennifer made 5 L of punch for her party. Her brother made another 750 mL. If they combine the 2 batches, how many 180 mL servin
USPshnik [31]

Answer:

31 servings

Yes there would be leftover

Step-by-step explanation:

In this question, we are asked to calculate the amount of a certain volume that would be had and if there also would be leftovers.

Firstly, to solve this question, we need to know the total volume made by the siblings.

Let’s convert What Jeniffer made to liters. It must be known that 1000ml is 1L. This means her 5L would be 5 * 1000 = 5000ml

Let’s add this to what her brother has and it would be 5000 + 750 = 5,750ml

Now they made a series of 180ml servings. We need to know how many of these would they have. We simply make a division: 5,750/180 = 31.94

There would be 31 of this and also there would be a remainder
