the scale factor ( y).

Answer:

Class width = 5

Mean = 20.375

Step-by-step explanation:

To find the class widths, find the difference between the upper and lower boundaries.

As there are gaps between the classes, the lower boundaries will be 0.5 less and the upper boundaries will be 0.5 more.

Class width = 10.5 - 5.5 = 5

To find the mean:

The easiest way to do this is to create a table (see attached).

[tex]\textsf{mean}=\dfrac{\sum fx}{\sum f}=\dfrac{815}{40}=20.375[/tex]

When the sectors of the circle are rearranged, they are close to forming a trapezoid with a length of 2*pi*r units and a width of r units.

The area of the rearranged figure is equal to that of the circle. So, the area of the circular base 2*pi*r square units.

A trapezoid is a two-dimensional geometric shape that has four sides with only two being parallel.

Answer:

x = 7

Step-by-step explanation:

Just write what you see in terms of a formula.

2x - 9 = 5

Solve for x

add both sides by 9

2x = 5 + 9

2x = 14

divide both sides by 2

x = 14/2

x = 7

Answer:

x = 7

Step-by-step explanation:

9 subtracted from 2x gives the result 5. Find the value of x.

Translate:

2x - 9 = 5

Simplify:

2x - 9 = 5 <== add 9 to both sides

    + 9  + 9

2x = 14 <== divide both sides by 2 to isolate the variable

/2    /2

x = 7

The total surface area of any given net of a rectangular prism = area of each rectangular face.

If we are given the net of a rectangular prism, the total surface area of the rectangular prism is the area of each rectangular face all summed together.

The image of the net of the rectangular prism is missing, however, let's assume the image attached below is the net of the prism.

Therefore, the total surface area of the rectangular prism = area of each rectangular face = 20 + 8 + 40 + 8 + 20 + 40 = 96 cm².

look up surface area calculator

Step-by-step explanation:

The surface area of the triangular prism is 161 square feet. Then the correct option is A.

Let h be the height and b be the base of the triangle. Let L₁, L₂, and L₃ be the length and W be the width of the rectangle. Then the surface area of the triangular prism will be given as,

Surface area = 2 Area of triangle + 3 Area of rectangle

Surface area = (h x b) + (L₁ + L₂ + L₃) x W

The surface area is calculated as,

SA = (5 x 5) + (5 + 5 + 7) x 8

SA = 25 + 17 x 8

SA = 25 + 136

SA = 161 square feet

Thus, the correct option is A which is top left.

Answer:

Caden is 11 and Christina is 24.

Step-by-step explanation: IF we know the sum of their ages is 35, then we can do the math. 35 - 11 = 24

So this means we know two ages 11 and 24.

The only thing left to do is to figure out who's age is who's. We know that Christina is older so she has to be 24 year old and Caden would be younger.

Step-by-step explanation:

Answer:

3 7/12

Step-by-step explanation:

First find the common denominator.

8,16,24

3,6,9,12,15,18,24

Once you find the common denominator. You have to fix the numerator.

7 2/8 would become 7 6/24

Whole numbers stay the same.

8 x 3 = 24

2 x 3 = 6

Now we repeat it on the other mixed number.

3 2/3 would become 3 16/24

Again whole numbers stay the same.

3 x 8 = 24

2 x 8 = 16

Once you convert the fractions to having the same denominator you subtract like normal.

7 6/24 - 3 16/24 = 3 14/24

3 14/24 can be simplified to 3 7/12

Answer:

[tex]\boxed{3 \dfrac{7}{12}}[/tex]

Step-by-step explanation:

The first step in simplifying the expression is to convert both the fractions into improper fractions [a/b (a > b)].

⇒ [tex]7\dfrac{2}{8} - 3\dfrac{2}{3}[/tex]

⇒ [tex]\dfrac{7 \times 8 + 2}{8} - \dfrac{3 \times 3 + 2}{3}[/tex]

⇒ [tex]\dfrac{56 + 2}{8} - \dfrac{9 + 2}{3}[/tex]

⇒ [tex]\dfrac{58}{8} - \dfrac{11}{3}[/tex]

The next step in simplifying the expression is to make the denominators of both fractions equivalent.

⇒ [tex]\dfrac{58}{8} - \dfrac{11}{3}[/tex]

⇒ [tex]\dfrac{58 \times 3}{8 \times 3} - \dfrac{11 \times 8}{3 \times 8}[/tex]

⇒ [tex]\dfrac{174}{24} - \dfrac{88}{24}[/tex]

The third step in simplifying the expression is to subtract the fractions.

⇒ [tex]\dfrac{174}{24} - \dfrac{88}{24}[/tex]

⇒ [tex]\dfrac{86}{24}[/tex]

The fourth step in simplifying the expression is to simplify the difference of the two fractions.

⇒ [tex]\dfrac{86}{24}[/tex]

⇒ [tex]\dfrac{86 \div 2}{24 \div 2}[/tex]

⇒ [tex]{\dfrac{43}{12}}[/tex]

The fifth step in simplifying the expression is to convert the improper fraction into mixed fraction.

⇒ [tex]{\dfrac{43}{12}}[/tex]

⇒ [tex]{\dfrac{36}{12}} + \dfrac{7}{12}[/tex]

⇒ [tex]3 + \dfrac{7}{12}[/tex]

⇒ [tex]\boxed{3 \dfrac{7}{12}}[/tex]

Answer:

The number would be 90

Step-by-step explanation:

140 + 10 - 90 = 60

90 - 30 = 60

60 = 60

Answer: 90

Step-by-step explanation:

Let's use x as a placeholder to the number we are trying to find

[tex]140+10-x=x-30[/tex]

Now we need to isolate x

Step 1) Simplify both sides

[tex]140+10-x=x-30\\150-x=x-30[/tex]

Step 2) Add 30 to both sides

[tex]150-x+30=x-30+30\\180-x=x[/tex]

Step 3) Add x to both sides

[tex]180-x+x=x+x\\180=2x[/tex]

Step 4) Divide both sides by 2

[tex]\frac{180}{2}=\frac{2x}{2} \\90=x[/tex]

Step 5) Sub our value into the original equation and solve

[tex]140+10-x=x-30\\140+10-90=90-30\\150-90=60\\60=60[/tex]
