The surface area is the area of all six sides when the object is a box.

Formula

SA = 2*L*w + 2*L*h + 2*w*h

Givens

L = 6 ft

w= 3 ft

h = 2.5 feet

Substitute and Solution

SA = 2*6*3 + 2*6*2.5 + 2*3*2.5

Answer:

False

Step-by-step explanation:

To calculate the unit price of an item, divide the total number of units by the total price is a "false statement." To calculate the unit price of an item, you have to understand that unit price means price per unit. To find the unit price we divide the total cost by the amount of items we are given in the question.

Example:

Sarah has 12 apples, she paid 20 dollars for all 12 apples, what is the unit price?

[tex]unitp=cost\div quantity[/tex]
[tex]unit=20\div12=1.66666667[/tex]
[tex]=1.66666667[/tex]

Round the answer to the nearest cent:
[tex]1.66666667[/tex]
[tex]6 > 5[/tex]
[tex]=1.67[/tex]

Which means the unit price of the 12 apples is "$1.67."

Hope this helps.

Answer:

1 : 4

Step-by-step explanation:

the scale factor is the ratio of corresponding sides , that is

4 : 16 = 1 : 4

For 3 sides to form a triangle two sides added together need to be greater then the 3rd side. You need to check all 3 combinations:

1. 11.5 + 10.5 = 22, 22> 6.1

11.5 + 6.1 = 17.6 17.6 > 10.5

10.5 + 6.1 = 16.6, 16.6 > 11.5

This one can make a triangle.

2. 9.5 + 3.5 > 4.5

9.5 + 4.5 > 3.5

4.5 + 3.5 < 9.5

Cannot make a triangle.

3. 8 + 6.7 > 1

6.7 + 1 < 8

Cannot make a triangle.

4. Can make a triangle

5. Can

6. Can

Can form triangle : 11.5,10.5, 6.1 & 8, 6.7, 9.8 & 5, 6, 8 & 9.5, 7.5, 8.5

Can not form triangle : 9.5, 3.5, 4.5 & 8, 6.7, 1

If sum of any two line segments is greater than the third line segment, then we can say that, they can make a triangle.

1st problem,

The given line segments are 11.5, 10.5, 6.1

Now, 11.5+10.5 = 22 > 6.1

10.5+6.1 = 16.6 > 11.5

11.5+6.1 = 17.6 > 10.5

So, this three segments can form triangle.

2nd problem,

The given line segments are 9.5, 3.5, 4.5

Now, 9.5+3.5 = 13 > 4.5

9.5+4.5 = 14 > 3.5

4.5+3.5 = 8 < 9.5

Here triangle inequality rule isn't applicable.

So, it can not form triangle.

3rd problem,

The given line segments are 8, 6.7, 1

Now, 8+6.7 = 14.7 > 1

8+1 = 9 > 6.7

6.7+1 =7.7 < 8

Here triangle inequality rule isn't applicable.

So, it can not form triangle.

4th problem,

The given line segments are 8, 6.7, 9.8

Now, 8+6.7 = 14.7 > 9.8

8+9.8 = 17.8 > 6.7

6.7+9.8 = 16.5 > 8

So, this three segments can form triangle.

5th problem,

The given line segments are 5, 6, 8

Now, 5+6 = 11>8

5+8 = 13 > 6

6+8 = 14 > 5

So, this three segments can form triangle.

6th problem,

The given line segments are 9.5, 7.5, 8.5

Now, 9.5+7.5 = 17 > 8.5

9.5+8.5 = 18 > 7.5

7.5+8.5 = 16 > 9.5

So, this three segments can form triangle.

Answer:

E. 4 cm

Step-by-step explanation:

Given:

Scale factor (R) = [tex] \frac{m_{image}}{m_{preimage}} = \frac{1}{3} [/tex]

AB = 12 cm

Required:

Length of A'B'

SOLUTION:

A'B' = length of the image = x cm

AB = length of the preimage = 12 cm

Thus, using the scale factor given, the length can be calculated as shown below:

[tex] \frac{m_{image}}{m_{preimage}} = \frac{x}{AB} = \frac{1}{3} [/tex]

[tex] = \frac{x}{12} = \frac{1}{3} [/tex]

Multiply both sides by 12

[tex] \frac{x}{12}*12 = \frac{1}{3}*12 [/tex]

[tex] x = \frac{12}{3} [/tex]

[tex] x = 4 [/tex]

x = A'B' = 4 cm

  "line of reflection."

Step-by-step explanation:

It appears as though the figure on the left is a reflection of the figure on the right across the line. Hence line P is the line of reflection.

Explanation

The given equation y = 2x+3 is in the form y = mx+b

Compare the terms to see that 2x matches with mx, so m = 2

The other term matches with b, so b = 3

m is the slope and b is the y intercept, so that's how I got those answers above.

Answer:

Step-by-step explanation:

Vertical angles are just angles formed by intersecting lines, there is no rule that states they must be acute (they can also be right or obtuse)

The option that is False is that Vertical angles are acute angles.

In mathematics, the term congruent means a figure, shape, or angle that has two equal parts, size, and length.

However, vertical angles assume a right angle and they are perpendicular to the straight line which makes them 90°, but we know that acute angles are angles that are less than 90°.

Therefore, we can conclude that vertical angles are not acute angles.

Rates are used to compare related quantities such as costs of items in two countries

The question is incomplete;

So, I will give a general explanation on how to calculate the rate.

Assume that the costs are:

United Kingdom = 500

Canada = 750

The ratio would be:

Ratio = United Kingdom : Canada

So, we have:

Ratio = 500 : 750

Simplify

Ratio = 2 : 3

Express as rate

Rate = 2/3

Using the assumed values, the rate of the total cost for items in the United Kingdom to that of the total cost of items in Canada is 2/3
