We know that the factory uses 3 3/4 per batch, and they used 7 1/2 barrels of raisin yesterday. Firstly, let’s convert our mixed fraction to an improper fraction. 3 3/4 is 15/4 and 7 1/2 is 15/2. I can now change the denominator of 15/2 to match 15/4. This gives me 30/4. This means our fractions are now 15/4 and 30/4. I can then divide 30/4 by 15/4 to give me 2. Therefore, our answer is 2. They created 2 batches yesterday.

(You don’t need common denominators to divide fractions, but it would be easier if I did it this way for this equation.

70 POINTS!

You can solve this question with pythagorean theorem > ${a}^{2} + {b}^{2} = c^{2}$

Based on the information, you already have one side (a or b, doesn't matter, 12) and the hypotenuse (the cut, c, 15)

So:
1. $12^{2} + b^{2} = 15^{2}$
2. 144+ $b^{2}$ = 225
3. $b^{2}$ = 225 - 144 = 81
4. $b= \sqrt{81}$
5. $b=9$

A poll was taken to determine which candidate students were voting for in an upcoming class president election. Of the students

hram777 [196]

Answer:

Step-by-step explanation:

the way to find how many participanted in the class voted, you need to look at the percentages and the number of students that voted for Vicky.

50% of students voted for Vicky and the question later explained that the total of the 50% was 30 students. This mean we know half of the student that participated. To find the total amount of students to make 100%, you need to multiple 30 by 2. which is 60.

Now that we know there were 60 students in total, we can find how many participated by using Iverson's percentage.

this is the formula that can help with any percentage math problem:

The percentage of something ÷ 100% = the number you are looking for ÷ the total

in our case:

40÷100 = x (because it is the unknown term)÷60

from here you cross multiple getting

2400÷100x

which equals

now we have to add Vicky's and Iverson's voter

24 + 30= 54

60-54=6

6 students did not participate

Find the distance d(P1, P2) between the points P1 and P2. P1 = (-5,3) P2 = (2,4) d(P1,P2) = (Simplify your answer. Type an exact

Reptile [31]

Answer:

distance between two points is

$5\sqrt{2}$

Step-by-step explanation:

the distance d(P1, P2) between the points P1 and P2

Use distance formula

$D= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

P1 = (-5,3) is (x1,y1) P2 = (2,4) is (x2,y2)

Plug in the values in the distance formula

$D= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\D= \sqrt{(2+5)^2+(4-3)^2}\\D= \sqrt{(7)^2+(1)^2}\\\\D= \sqrt{50}\\D=5\sqrt{2}$
