On Monday, 220 students went on a trip to the zoo. All 4 buses were filled and 8 students had to travel in cars. How many students were in each class and what is the algebraic equation to this?

Answers

If you would like to know how many students were in each class, you can calculate this using the following steps:

4 buses * x + 8 students = 220 students
4 * x + 8 = 220
4 * x = 220 - 8
4 * x = 212 /4
x = 212 / 4
x = 53

53 students were in each bus.

the size of a computer screen is measured along the diagonal. what is the approximate size measured to the nearest inch, of a 12 inch by 10.5 in computer screen

Answers

In this exercise we have to use the knowledge of pythagoras and triangles to calculate the size of a canvas, in this way we find that;

$15.945 inch$

So knowing that the Pythagorean formula is given by:

$a^2=b^2+c^2$

Substituting b and c for the values informed in the exercise we find that:

$a^2=144+110.25 \n a^2=254.25 \n a=15.945$

See more about pythagoras at brainly.com/question/10174253

This uses pythagoras which is a^2=b^2+c^2. You need to find the diagonal which is "a". Therefore a^2=144+110.25 which equals 254.25 then square root it and you get 15.945

Of the 200 packages of bagels sold 15 of them are sesame seed bagels what percent of the bagel packages sold are sesame seed bagels

Answers

Of the 200 packages of bagels sold, 15 of them are sesame seed bagels. What percent of the bagel packages sold are sesame seed bagels?

The fraction $(15)/(200)$ represents the number of sesame seed bagel packages out of all the packages.

To find out what percent are sesame seed bagel packages, we can turn the fraction $(15)/(200)$ into a percent.

We can first reduce the fraction $(15)/(200)$ by dividing both the numerator and denominator by the Greatest Common Factor of 15 and 200 using 5.

15 ÷ 5 = 3

200 ÷ 5 = 40

3 ÷ 40 = 0.075

0.075 × 100 = 7.5%

Therefore, 7.5% of the bagel packages sold were sesame seed bagels.

15 = x% from 200
15 = * 200
15 = 2x / ÷ 2 (both sides)
x = 7.5 [percent]

explain how you can use multiplication to find the quotient 3/5 divided by 3/15. then evaluate the expression

Answers

we know that

Dividing is the opposite of multiplying. Therefore, dividing by a fraction can be accomplished by multiplying by its reciprocal

$((a)/(b))/((c)/(d)) =(a)/(b)*(d)/(c)$

in this problem we have

$(a)/(b)=(3)/(5)\n \n(c)/(d)=(3)/(15)$

substitute in the formula above

$((3)/(5))/((3)/(15)) =(3)/(5)*(15)/(3)=3$

therefore

the answer is

$3$

$(3)/(5)$ ÷ $(3)/(15)$

⇒ $(3)/(5)$ × $(15)/(3) = (45)/(15) = 3$
