Answer 1

Answer:

1.D 2. A 3.C 4.D

1 Is the monomial as it only contains one expression.

2. Is the difference of squares because something squared minus something squared.

3. Is standard because it is of the form

$a_nx^n+ a_(n-1)x^(n-1)+...+a_1x+a_0$

4. We know D is the not the monomial simply because its power is negative which means it does not fit the definition of a polynomial.

Bradley is in a class of 15 boys and 10 girls. 40% of the class takes the bus to school. How many students do not take the bus to school?

Answers

Answer:

30 Students

Step-by-step explanation:

As given

Bill is in a class of 15 boys and 35 girls.

Total number of students in the class = Number of boys + Number of girls

= 15 + 35

= 50

As given

40% of the students in the class take the bus to school.

40% is written in the decimal form.

= 0.40

Number of students take bus to school = 0.40 × Total students in class.

= 0.40 × 50

= 20

.Thus

Students not take bus to school = Total students - Number of students take bus to school

= 50 - 20

= 30

Therefore 30 students not take bus to school .

Answer:

15 students

Step-by-step explanation:

First of we have to calculate how many students there are in the class. There are 15 boys and 10 girls, whish means there are 25 people in total (15+10=25).

Since 40% takes the bus to school, 60% of the sudents do not take the bus to school. The easiest way to calculate how many students is 60% is to first divide the students with 10. 25/10 is 2.5. 2.5 students is 10% of 25 students (100% divided by 10 is 10%).

To get 60%, the number of students has to be multiplied with 6, because 10% times 6 is 60%.

2.5 (10%) times 6 is 15, so the answer is 15.

If one gallon is the same amount as 16 cups, how many cups equal 2.5 gallons? (Only input whole numbers.)

Answers

Answer:

Step-by-step explanation:

Hello, I think I can help you with this

you can solve this easily using a simple rule of three

Step one

define the relation and solve for x

1 gallon ⇒16 cups

2.5 gallons⇒x cups?

$(1)/(16) = (2.5)/(x) \nisolate\ x\n(1*x)/(16)=2.5\nx=(2.5*16)/(1) \nx=40$

so, 2.5 gallons is the same amount as 40 cups

I hope it helps, Have a fantastic day.

40 cups, 16+16=32, 32+1/2 16=40, 16÷2=8:) hope i helped

Answers

To do these, always convert the percents to decimals, so you can subtract it from 1. Remember, 1 is the whole. When you subtract the part that's taken off, you are left with what you have to pay. If you have 20% off of $100, then you are paying for 80% of $100. **of means to multiply** so you would multiply: 0.8X100, which would be $80.

First, multiply 125x0.8

Multiply that answer by 0.7

You should get B. $70

3) multiple 22.90x0.93

You should get D

2) B. $70
First you multiply 125 by 20%, but put the percent to a decimal then subtract and of the same with the 30% just add on to it

3) first you multiply 22.90 and .07 and add
