When a teacher counted her students in groups of 4, there were two students left over. When she counted them in groups of 5, she had 1 student left over. If 15 of her students were girls and she had more girls than boys, how many students did she have?

Answers

Answer 1
There’s 16 students - 15 girls and 1 boy

Number of students in class = x students

X is two more than a multiple of 4

So x is an even number because multiples of 4 are even & adding 2 would mean it’s still equal

X is 1 more than a multiple of 5. We know x is an even number. It has to be a multiple of 5 ending in 5 not 0
5 + 1 = 6

All multiples of 4 ending in 6 are 16, 36, 56...

Since there are 15 girls and there are less boys than girls

16 - 15 = 1

Therefore there’s 16 students

Tasha is packing gift bags that include

the same items. She has 72 glow sticks,

36 markers, and 24 bottles of bubbles.

Tasha believes that she can pack no

more than 6 bags using all of her

supplies. Do you agree with Tasha? Explain.

Answers

Answer:

No, I do not.

She can pack up to 12 bags

Step-by-step explanation:

Given

[tex]Glow\ sticks = 72[/tex]

[tex]Markers = 36[/tex]

[tex]Bubbles = 24[/tex]

Required

Is Tasha correct?

The maximum number of bags she can pack is determined by the greatest common factors (GCF) of the items.

i.e. GCF of 72, 36 and 24.

This is calculated as:

[tex]24 = 2*2*2*3[/tex]

[tex]36 = 2 * 2 *3*3[/tex]

[tex]72 = 2 * 2 * 2 *3*3[/tex]

Multiply all common factors:

[tex]GCF = 2 * 2 * 3[/tex]

[tex]GCF = 12[/tex]

The GCF is 12.

This implies that she can pack up to 12 bags

What is the sum of the interior

that has 7 sides?
Sum = [?]
Hint: Sum = (n-2)180

Answers

Answer:

Sum = 900 degrees.

Step-by-step explanation:

Sum = (n-2)180

=(7-2)180

=(5)180

=900

Answer:

900 degrees

Step-by-step explanation:

The formula for calculating the sum of the interior angles of a regular polygon is : ( n - 2) × 180°. when n is number of sides.

Sum of angles = ( n-2) × 180

Sum of angles = (7-2) × 180

Sum of angles = 5 × 180

Sum of angles = 900 degrees

1. Rita has 3 ¾ cups of potato chips to share with 6 friends. How many cups does EACH friend get

Answers

Answer:

Each friend will get 5/8 (excluding Rita)

Each person will get 15/28 (including Rita)

Step-by-step explanation:

You must simply divide 3 3/4 ÷ 6 (excluding Rita)

You must simply divide 3 3/4 ÷ 7 (including Rita)

5/8 cups

You divide 3 3/4 by 6 so

3.75/6 = 0.625

Then make that back into a fraction
0.625= 5/8
