A school ordered 32 orange shirts, 29 blue shirts, and 34 green shirts. The shirts are being divided equally among 6
classrooms. If each classroom gets the same number of shirts, how many shirts will be left over?
A. 5
B. 3
C. 4
D. 2

Answers

Answer:

5

Step-by-step explanation:

32+29+34= 95 total shirts

95/6=15.8333 round down

If each group get 15 shirts you need 90 shirts (15*6=90)

and so you will have 5 left over (95-90=5)

There are 57 ounces of cereal in 5 boxes. At this rate, how many ounces of cereal are in 8 boxes?

Answers

Answer:

91.2

Step-by-step explanation:

If there is 57 ounces in 5 boxes and you divide 57 by 5 you'll get 11.4. After that you should times 11.4 by 8 to get 91.2 ounces

Answer:

91.2 ounces

Step-by-step explanation:

Let's make a proportion using this setup:

ounces/boxes=ounces/boxes

There are 57 ounces in 5 boxes, and x ounces in 8 boxes.

57 ounces/5 boxes= x ounces/8 boxes

57/5=x/8

Now we have to solve for x. x and 8 are being divided. To undo this, multiply both sides by 8, because multiplication is the opposite of division.

8*57/5=x/8*8

The 8s on the right will cancel, so we are left with:

8*57/5=x

8*11.4=x

91.2=x

There are 91.2 ounces in 8 boxes

in 1900, greenville had a population of 4000 people. Greenville's population increased by 100 people each year. Springfield had a population of 1000 people. Springfields population increased bu 4% each year. In what year were the populations about equal?

Answers

Answer: year 1948

Step-by-step explanation:

1900 is our t = 0

The population of Greenville can be written as:

G = 4000 + 100*t

the equation for Springfield can be written as:

S = 1000*(1.04)^t

we want to find the value of t that makes S(t) = G(t)

4000 + 100*t = 1000*(1.04)^t

(4000 + 100*t) = 1.04^t

4 + 0.1*t = 1.04^t

now, you can graph both of this equations (left side and right side) and see in wich value of t the graphs intersect eachother, or you also may use different values of t until the values are about the same for both sides, which is the thing i did with the equation:

4 = 1.04^t - 0.1*t

You will find that the correct value is t = 48

So we can assume that in year 1948 the populations will be about the same.

Given that ACDE, CBFG, and ABIH are squares and the side of the equilateral △ABC is 1 in. Find the square of the value of the shaded area.

Answers

Answer:

  6.75

Step-by-step explanation:

The shaded area amounts to two congruent equilateral triangles. Each has a side length of 2(1 in)cos(30°) = √3 in.

The height of an equilateral triangle with side length √3 is ...

  height = (√3 in)sin(60°) = 3/2 in

Then the area of the two equilateral triangles is ...

  A = bh = (√3 in)(3/2 in) = 3√3/2 in^2

The square of the numerical value of the area is ...

  A^2 = ((3/2)(√3))^2 = 27/4 = 6.75

The square of the shaded area is 6.75.

Which expression can be used to find 17% of 58?
A. 58 = 0.17 B. 58 = 17
C. 58 x 0.17
D. 58 x 17

Answers

Answer:

58 times 0.17 which agrees with answer C in the given list of possible answers.

Step-by-step explanation:

Notice that 17% in math terms is 17/100 = 0.17

Now to find the 17% of the number 58, we need to multiply 58 by 17/100, which gives:

58 times 0.17

Answers

Step-by-step explanation:

m∠2 = 180-150 = 30

m∠3 = 180-(80+30) = 180 - 110 = 70

using the law of sine :

AC/sin(m∠2) = 5/sin(m∠3) ⇒ AC = sin(m∠2)*(5/sin(m∠3)) = sin(30)×(5÷sin(70))

=2.66044443119

CB/sin(m∠1) = 5/sin(m∠3) ⇒ CB = sin(m∠1)*(5/sin(m∠3)) ⇒ CB = sin(80)×(5÷sin(70)) = 5.240052604588

Going from 1 to 7. The not functions are 2,4,6, and 7

Step-by-step explanation:

How you can determine if its a function is if all x values are different. Vertical line test.

Using the function concept, it is found that these following relations are not functions:

(1,3), (1,7), (5,11), (5,15), (9,19)

(2,4), (1,1),(0,0), (1,-1), (2,-4)

(1,3), (3,11), (3,7), (7,15), (9,19)

(1,3), (3,7), (5,11), (9,15), (9,19)

A relation is a function if one input is mapped to only one output.

In the relation (1,3), (1,7), (5,11), (5,15), (9,19), the input 1 is mapped to the output 3 and to the output 7, so it is not a function.In the relation (2,4), (1,1),(0,0), (1,-1), (2,-4), the inputs 2 and 1 are mapped to multiple outputs, so it is not a function.In the relation (1,3), (3,11), (3,7), (7,15), (9,19), the input 3 is mapped to the outputs 11 and 7, so it is not a function.In the relation (1,3), (3,7), (5,11), (9,15), (9,19), the input 9 is mapped to the outputs 15 and 19, so it is not a function.

Answer:

-23

Step-by-step explanation:

x = -5 lies in the last piece

h(-5) = 4(-5) - 3

= -20 - 3

= -23

Step-by-step explanation:

Step 1:  Find which piece-wise function it is in

Equation 1 → x < -7

Let x = -5 → (-5) < -7 ← False

Equation 2 → -7 ≤ x < -5

Let x = -5 → -7 ≤ (-5) < -5 ← False

Equation 3 → x ≥ -5

Let x = -5 → (-5) ≥ -5 ← True

Step 2:  Find the value of h(-5)

[tex]h(-5) = 4x - 3[/tex]

[tex]h(-5) = 4(-5) - 3[/tex]

[tex]h(-5) = -20 - 3[/tex]

A salesman made a trip of 420 miles by bus and train. He traveled 3 hours by bus and 5 hours by train. If the train averaged 12 mph more than the bus, find the rate of each.

Answers

Answer:

The speed at which the buss made the trip was 45 mph and the train was 57 mph.

Step-by-step explanation:

The average speed is given by:

speed = distance / time

Therefore we can manipulate it to give us the distance:

distance = speed*time

The time distance of each stage of his trip summed must be equal to the total distance of the trip. Since he made a trip in two legs, one by bus that lasted 3 h at a speed of "x" and one that lasted 5 hours at a speed of "x + 12". We have:

420 = 3*x + 5*(x + 12)

3*x + 5*(x + 12) = 420

3*x + 5*x + 60 = 420

8*x = 420 - 60

8*x = 360

x = 45 mph

The speed at which the buss made the trip was 45 mph and the train was 57 mph.

Answer:

45 mph

Like any historical event, the causes of the Civil War were complicated, but the biggest underlying issue was the disagreement concerning slavery. Some historians have said that economics was the main cause. They argue that the agricultural system of the South was at odds with the industrial, free labor system of the North. The economy of the South revolved around agriculture and slavery. The South was completely committed to a single crop, cotton, which was picked entirely by slave labor. Therefore, virtually all of the labor in the South was slave labor. Many in the northern states felt that slavery was morally wrong, but this was just one cause for concern. The North also worried that slave labor would undermine the position of free white laborers. People in the North worried that the South had intentions to expand slavery, which would make it hard for white laborers to find work. Still other historians might argue that a rise in sectionalism was the cause of war. The nation seemed to be splitting down social and political lines, becoming two different cultures that embraced very different ideas. These cultures were most strongly divided, however, on the issue of allowing slavery and not allowing slavery. The southern states believed they had the right to practice slavery. To them, ending slavery would mean an end to their culture. Due to these societal differences, the North and South found it difficult to agree on political issues. The two areas of the country grew further apart until it seemed that war was inevitable.Which of the following choices best describes the opinion of the author of the passage above?A.
