Answer: 35 girl costumes, 25 boy costumes.


Step-by-step explanation:

60 split into 2 groups is 30 each.

Add 5 to one group and subtract 5 from the other to get a difference of 10.

Girls group is 30+5=35

Boys group is 30-5=25

Answer:

<em>They will need 25 boy costumes and 35 girls costumes.</em>

Step-by-step explanation:

There are x boys.

There are x + 10 girls.

Altogether, there are x + x + 10 students.

Altogether, there are 60 students, so

x + x + 10 = 60

2x + 10 = 60

2x + 50

x = 25  (boys)

x + 10 = 35  (girls)

The formula
son4ous [18]

Answer:

The truck travel must to have a constant speed of 22.06\ ft/sec

Step-by-step explanation:

we have

d=1.3t^{2}+t+2

where

d expresses a car's distance in feet

t is the number of seconds

<em>Find the distance d for t=8 sec</em>

d=1.3(8)^{2}+8+2=93.2\ ft

<em>Find the distance d for t=8.2 sec</em>

d=1.3(8.2)^{2}+8.2+2=97.612\ ft

The total distance in this interval of 0.2 sec is

97.612-93.2=4.412\ ft

<em>Find the speed of the car</em>

Divide the total distance by the time

4.412/0.2=22.06\ ft/sec

therefore

The truck travel must to have a constant speed of 22.06\ ft/sec

15/10 to a mixed number
tensa zangetsu [6.8K]
First, we have to find how many times 10 goes into 15.

We can divide 15 by 10, and we will see that 10 goes into 15 1 whole time, with 5/10 left over.

Now, we can simplify!

In order to simplify, we have to find the GCF (greatest common factor) of 5 and 10. Let's list out the factors (the numbers that can be divided into 5 and 10)

1*5

1*10
2*5

The largest factor, as we can see, is 5! Let's dicide 5/10 by 5.

5/5=1
10/5=2

So, 5/10 simplifies to 1/2, and, if we bring down the whole number we found before, 15/10 is equal to 1 and 1/2! :)

We can check this answer by multiplying the whole number, 1, by the denominator, (the bottom number of a fraction) 2, and adding the numerator, (the top number of a fraction), 1.

1*2=2
2+1=3

Keep the denominator as 2.

The improper fraction is 3/2, which is equivalent to 15/10 (multiply 3/2 by 5 to see)!

So, our answer is 1 1/2.

I hope I helped! :)
