Step-by-step explanation:

Number of students in Jacob's homeroom = 20.

Number of students who bring their lunch to school = 5

Since the rest eat lunch in the cafeteria, the number of those who eats in the cafeteria will be:

= 20 - 5

= 15

Fraction that eats in the cafeteria will be: = 15/20 = 3/4

Answer:

1/3

Step-by-step explanation:

because smaller the fraction bigger the pieces so 1/3 will be greater than 2/3 :)

Answer:

any number that is more than 2/3

so you can put 3/4 or/3

Step-by-step explanation:

135+25+5x=180°

160+5x=180

5x=20

x=4

Answer:

(-4, 2)

Step-by-step explanation:

X+4=0

x= - 4

When you get this value, you have the x value of the minimum. That's because you have made the x value 0. Any other value will turn the y value into a number greater that 2.  In other words, the absolute value is larger than 0, so the y value is greater than 2.

The vertex is (-4,2) .  I have enclosed a graph to show what this will look like when graphed.

Don't do anything until I check this. I'm using my phone.  You are the first person I have tried to use my phone on. It's not as good as my computer. This is the final answer.

Bru I’m in ur class and it’s The median

Step-by-step explanation:

It’s the median

Out of all the options listed, the only one that does not show variation (spread) is the median.

The median is simply used to show the medium value of a data set. It cannot be used to tell the variation because it does not take into account all the values but rather the middle one alone.

The other options are wrong because:

In conclusion, only the median does not help with finding the variation of a dataset.

Answer:

They will be at the same position after 2 hours.

Step-by-step explanation:

Here, it should be asked the time it will take for Anita to catch Brad.

Anita began riding at start of the path and is riding at rate of 18 mile per hour.

This means that, after t hours, her position will be given by:

[tex]A(t) = 18t[/tex]

Brad begin from a sport 10 mile ahead of her and I riding at rate of 13 mile per hour

This means that, after t hours, his position will be given by:

[tex]B(t) = 10 + 13t[/tex]

After how much time will they be at the same position?

This is t for which:

[tex]A(t) = B(t)[/tex]

So

[tex]18t = 10 + 13t[/tex]

[tex]5t = 10[/tex]

[tex]t = \frac{10}{5}[/tex]

[tex]t = 2[/tex]

They will be at the same position after 2 hours.

Step-by-step explanation:

square of 44 + 77

1st step = go with the number that is inside the square

that will 44+77 = 121

now using the square root , you may think about which number multiple by himself give you 121

Answer:

730 x 0.028 = (assuming per year) 20.44

20.44 x 5 = 102.2

102.2 + 730 = 832.2

Your final answer is 832.2

Step-by-step explanation:

Hope this helps!

The value of amount will be in Jean's account after 5 years is,

⇒ Amount = $832.2

The multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

We have to given that;

Jean deposits $730 in an account that pays 2.8% simple interest.

And,  He neither adds more money nor withdraws any mone from his account.

Now, We know that;

Interest = PRT / 100

Where, P is principal amount,

R is rate

And, t is time.

Hence, Substitute the values we get;

Interest = 730 x 2.8 x 5 /100

            = $102.2

Hence, The value of amount will be in Jean's account after 5 years is,

⇒ $730 + $102.2

⇒ $832.2

Therefore, The value of amount will be in Jean's account after 5 years is,

⇒ Amount = $832.2
