Answer 1

Answer:

There are 24 students and teachers that rode in vans, and there are 385 students and teachers that rode in buses.

Step-by-step explanation:

First we are going to set up a system of equations where:

b= number of buses

v= number of vans

We know from the equation that each bus transported 55 people and that each van transported 12 people and that there was a total of 409 people transported. We also know that the number of buses was 5 more than the number of vans.

Knowing that we can set up our system:

[tex]\left \{ {{55b+12v=409} \atop {b=v+5\\}} \right.[/tex]

Since we know what b is equal to, we can now use the substitution method to plug the value of b from the bottom equation into the one on the top and solve for variable v.

55(v +5)+12v =409

From there we can distribute 55 into (v+5)

55v +275+12v =409

We can now combine like terms.

67v +275 = 409

From there we subtract 275 from both sides of the equation to isolate the variable.

67v +275 = 409

      -275    -275


After doing this, we now divide both sides of the equation by 67 to solve for v.

[tex]\frac{67v}{67} =\frac{134}{67}[/tex]

We now know that v, the number of vans is 2 and can plug that into our bottom equation from our system of equations ([tex]b=v+5[/tex]).

[tex]b=2+5\\b=7[/tex]

Knowing that there are 7 buses and 2 vans, we can now plug these numbers into the terms in the top equation of our system. 55b and 12v.

[tex]55(7)=385[/tex]

[tex]12(2)= 24\\[/tex]

385 people rode buses. 24 people rode vans

Check your equation

409 people went in total. 385 + 24 = 409.

The Smith family went to eat at Buffalo Wild Wings. The bill was $43.86. They gave the server a 20% tip. How much did they pay altogether?

Answers

Answer:

$52.63

Step-by-step explanation:

To find 20% of $43.86 we multiply $43.86 by 0.2

$43.86 • 0.2 = $8.772

Now add $43.86 and $8.772 to find out how much the family paid altogether.

$43.86 + $8.772 = $52.632

In money the smallest place value is cents so we have to round to the hundredths place.

Doing this we get the grand answer of:

$52.63

52.63

To find the altogether cost of the meal including tip you need to multiply the bill ($43.86) by 1.20

43.86(1.2) = 52.632

Same would go for if you were leaving a 10% tip but you would multiply by 1.10

Answers

Answer:

4 miles per hour

Step-by-step explanation:

Unit rate is the rate of something per 1 unit. In other words, the unit rate is x units per 1 unit. In this situation, the unit rate is how many miles Hassan walks in 1 hour.

Proportion

First, to find the rate of anything we can set up a proportion. In the question, the rate is described as miles per hour, so the miles will be the numerator and the hours will be the denominator.

This creates the proportion [tex]\frac{12miles}{3hours}[/tex]

So, the rate we are given is 12/3.

Unit Rate

To find the unit rate we need to make the denominator equal to 1. To do this, divide both the numerator and denominator by 3.

12/3 equals 43/3 equals 1

So, this means that the new proportion is 4/1. Next, we can add our units, which means that Hassan walks 4 miles per 1 hour.

Graph

Now we can resize the bar graph. The purple bar should be set to 4 because this represents the miles. Then, the green bar should be set to 1 because it represents the hours.

4 miles per hour bc that's what the answer is

Answers

Answer:

Step-by-step explanation:

A, B, D, and E are all true. A is true because 5/5 equals a whole, and because the fraction is 4/5 in terms of negative numbers, it’s greater than -1 because it is closer to 0. B is correct because 1/5 is equal to 2/10, or 0.2, and 0.2 is greater than -0.3. D is correct because 0 is the origin, and -0.5 is below 0. E is correct because -3/5 is equal to -60%, or -0.6.

Aakesh has two bags of marbles. The first bag contains 6 red marbles, 4 blue
marbles, and 5 green marbles. The second bag contains 3 red marbles, 1 blue
marble, and 5 green marbles. Aakesh will randomly select one marble from
each bag.
What is the probability that Aakesh will select a green marble from each bag?


A. 4/9

B.1/3

C. 5/9

D. 5/27

Answers

The answer for the 1st bag is option B = 1/3

The answer for the 2nd bag is option C = 5/9

Number of marbles in 1st bag - 15 (6 red, 4 blue & 5 green)

Number of marbles in 2nd bag - 9 (3 red, 1 blue & 5 green)

The formula of probability = Total number of events in the outcome /total number of outcomes.

Now the probability that Aakesh will select a green marble from the 1st bag is 5(green marbles)/15(total number of marbles in 1st bag)

That is 5/15=1/3

Now the probability that Aakesh will select a green marble from the 2nd bag is 5(green marbles)/9(total number of marbles in 1st bag)

That is 5/9

C.) 5/9

☆☆●◉✿Step-by-step explanation:✿◉●☆☆

First we must figure out how many marbles we have in total.

Meaning we will add all of the marbles together in bag one and then bag two.

Bag one: 6+4+5= 15

Bag two: 3+1+5= 9

Total= 24 marbles

Now we will try and figure out how many greens are in the total amount of marbles.

Amount of green marbles in bag one: 5

Amount of green marbles in bag two: 5

Total green marbles: 10

The third and final step!

10/24 is the amount of green marbles so the answer is C!

Which figure is a trapezoid?

Answers

Answer:

none of those

Step-by-step explanation:

A trapezoid is a 4-sided shape with 1 parallel side

Could you pls choose this as brainliest???!!!

The answer would be a four sided shape with one set of parallel sides. Parallel sides are two sides that will never touch or intersect. To further explain, if we take the left and right sides of the trapezoids and extend them, they will eventually intersect meaning that they aren’t parallel. This will go for and trapezoid, no matter the side lengths. However, if we take the top and bottom sides of a trapezoid and extend them left and right, we will find that they will never intersect which is how we know that a trapezoid only has one pair of parallel sides.
