What is the surface area of this right rectangular prism?

Enter your answer in the box.

The answer is -3.

5-2/2-3 = -3

Answer:

3/8 yards

Step-by-step explanation:

3/4 yard tall and 1/2 yard wide

Multiply the two fractions

3/4 (1/2)

= 3/8 yards

If the width of the rectangular painting is one unit then the height of the painting will be 3/8 yards. Then the correct option is A.

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.

A painting is going to be reprinted as a poster.

The dimensions of the painting are 3/4 of a yard and 1/2 of a yard wide.

The poster company is trying to determine how big to make the poster For each yard of width,

Let h be the height of the poster. Then we have

[tex]\rm h \times 1 = \dfrac{3}{4} \times \dfarc{1}{2}\\\\h \ = \dfrac{3}{8}[/tex]

If the width of the rectangular painting is one unit then the height of the painting will be 3/8. Then the correct option is A.

Answer:

48,58

Step-by-step explanation:

Let The speed of the west bound train be x

Let the east bound train be x+10

The speeds can be calculated as follows

2(2x+10)= 232

4x + 40= 232

4x= 232-40

4x= 192

x= 192/4

= 48

Hence the speedof the west bound train is 48

The speed of the east bound train is 48+10

= 58

Step-by-step explanation:

We would expect that 4 of the next 9 children to enroll will be elementary school students.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

If 8 out of the last 18 children to enroll at the daycare center were elementary school students,

We can find the fraction of elementary school students in that group by dividing the number of elementary school students by the total number of children:

= 8/18

= 4/9

This means that 4 out of every 9 children enrolled were elementary school students.

If we want to predict how many of the next 9 children to enroll will be elementary school students,

We can use this ratio:

4/9 of 9 children

= (4/9) x 9

= 4

Therefore,

We would expect that 4 of the next 9 children to enroll will be elementary school students.

Answer: The answer is 42

Step-by-step explanation:

I did the test too :)

The weight of clothing for which the ratio of weight to dye is different from the other ratios is 42 pounds.

To determine which weight of clothing has a ratio of weight to dye different from the other ratios, we need to compare the ratios for each weight.

Let's calculate the ratios for each weight of clothing by dividing the weight of clothing (in pounds) by the cups of dye:

For 21 pounds of clothing: 21 pounds / 3 cups = 7 pounds per cup

For 42 pounds of clothing: 42 pounds / 9 cups = 4.67 pounds per cup

For 84 pounds of clothing: 84 pounds / 12 cups = 7 pounds per cup

For 105 pounds of clothing: 105 pounds / 15 cups = 7 pounds per cup

From the calculations, we can see that for weights of 21 pounds, 84 pounds, and 105 pounds of clothing, the ratios of weight to dye are the same, which is 7 pounds per cup. However, the ratio for 42 pounds of clothing is different, which is 4.67 pounds per cup.

Therefore, the weight of clothing for which the ratio of weight to dye is different from the other ratios is 42 pounds.

y = (x + 9)² -93

vertex: (-9, -93)

Step-by-step explanation:

x² + 18x = 12

Answer:

The investment will be worth $450 after 25.255 years which is about 25 years and 3 months.

Step-by-step explanation:

You have to use the following formula to calculate the number of years:

t=ln(A/P) / n(ln(1 + r/n)), where:

t=time in years

A=Accrued amount=450

P=Principal amount=100

n=number of compounding periods per time period=4

r=interest rate=0.06

Now, you can replace the values in the formula:

t=ln(450/100)/4(ln(1+(0.06/4)))

t=ln(4.5)/4(ln(1.015))

t=1.50/0.059

t=25.255

According to this, the answer is that the investment will be worth $450 after 25.255 years which is about 25 years and 3 months.

Answer:

1200 square inches

Step-by-step explanation:

First find area of rectangle which is length x width

20 x 30 = 600

then to find area of the two right triangles multiply the legs then divide by 2

20 x 30 = 600

600/2 = 300

since there is 2 multiply 300 by 2

600

then add everything together

600+600 = 1200

Answer:

7. 80 miles

8. F

Step-by-step explanation:

7. Jorge leaves 2 hours early, and is going 20 miles per hour. So before Marcos starts going, Jorge has gone 40 miles (2*20). Then, 1 hour later, Jorge is at 60 miles and Marcos is at 40 (because he goes 40 miles per hour in his car). Another hour later, Jorge is at 80 (60+20) and Marcos is at 80 as well (40 + 40). They will both have gone 80 miles when Marcus catches up.

8. You want to get a isolated.

A = h/2(a + b)

First, multiply both sides of the equation by the reciprocal of h/2.

2A/h = a + b

Then, subtract b from both sides.

The scale factor is 1/3

Step-by-step explanation:

Here, we want to get the scale factor used in dilating the original segment

As we can see;

(9,3) turned to (3,1)

looking at this , we can see that both coordinate values were divided by 3

So what this mean is that the particular scale factor used is reduction by 1/3

This is the case with the other point as (-6,-9) turned to (-2,-3)
