Answer: 30 on both.

Step-by-step explanation: 30 because 3x3 is 9 so then add a zero

Answer: Area is length multiplied by width.

90=10×9

Step-by-step explanation: The sides will be multiplied to get the area.

10 And 9 are the sides

Answer:

47

Step-by-step explanation:

a)

a^2 + b^2 = c^2

33^2+33^2=c^2

2178=c^2

c=(nearest is 47)

b)

If you cut the square in half diagonally, it forms two right triangles with angle measures 90-45-45. You can use sin (opposite over hypotenuse) to find the length of the hypotenuse.  sin (45) would be 33/(hypotenuse length). From a trig chart, you can find that sin (45) is 1/sqrt(2), meaning that 33/x = 1/sqrt(2). This means that x=33sqrt(2), which is around 47.

The length of the diagonal of Stacy's ceiling is 46,7.

Pythagoras Theorem (also called Pythagorean Theorem) is an important topic in Mathematics, which explains the relation between the sides of a right-angled triangle.

The ceiling of Stacy's living room is a square that is 33 ft long on each side. Stacy knows the diagonal of the ceiling from corner to corner must be longer than 33 ft, but she doesn't know how long it is.

By using Pythagoras theorem;

[tex]\rm Hypotenuse ^2=33^2+33^2\\\\ Hypotenuse ^2=1089+1089\\\\ Hypotenuse ^2=2178\\\\ Hypotenuse =46.9\\\\[/tex]

By using trigonometry;

[tex]\rm Cos45=\dfrac{33}{d}\\\\d =\dfrac{33}{cos45}\\\\d=46.7[/tex]

Hence, the length of the diagonal of Stacy's ceiling is 46,7.

Answer:

4 × (x - 2)

Step-by-step explanation:

we want to transform 4x - 8 from a difference of two terms into a product of two factors​ :

4x - 8 is a the difference of the terms 4x and 8

4x - 8 = 4x - 4×2 = 4 × (x - 2)

4 × (x - 2)  is the product of the two terms 4 and x - 4

Answer:

SA = 3.04 m²

Step-by-step explanation:

→ Find: Surface Area (SA)

SOLUTION:

→ SA = 2(1x0.8) + 2(0.4x0.8) + 2(1x0.4)

→ SA = 1.6 + 0.64 + 0.8

↓

SA = 3.04 m²

Answer: $17.55

Step-by-step explanation:

    We will multiply the bill by 117% to account for the original amount and the tip being given.

117% / 100 -> 1.17

$15 * 1.17 = $17.55

     Sarah should leave $17.55 in total.

Answer:

1800 square feet

Step-by-step explanation:

Area of composite figure

Figure 1:

length = 27 ft

Width = 24 ft

Area of figure1 = length * width

                        = 27 * 24

                        = 648 square feet

Area of figure II:

              length = 27 ft

              Widht = 32 ft

Area of figure II = 27 *32

                          = 864 square feet

Area of figure III:

    base = 18 ft

     height = 32 ft

[tex]\text{Area of triangle (figure III) = $\dfrac{1}{2}*base*height$}\\\\[/tex]        

                                            [tex]= \dfrac{1}{2}*18*32\\\\= 288 \ square \ feet[/tex]

Area of composit figure = 648 + 864 + 288

                                        = 1800 square feet

After find the area of one side, we proceeded to find the length and with as

Length = 10.95 feet width = 10.95 feet

Given Data

If the area of 4 side = 480 ft^2

Area of 1 side will be = x

Cross multiply we have

x = 480/4

x = 120 ft^2

Let us find the length and width of the room

x = √120

x = 10.95 feet

hence Length = 10.95 feet

width = 10.95 feet

Height = 10 feet

Answer:

8 $10 notes

Step-by-step explanation:

I started by working it backwards. $93-$3 equals $90. So we have three of our 13 notes. We need ten more. Well the most $10 notes we can have is 8. if we had 8 $10 notes that would give us $80. $90-$80=10. We can take ten and divide it by five so we have 2 $5 notes.

So in total he would have 8 $10 notes, 2 $5 notes, and $3 one dollar notes which adds up to 13 notes

Answer:

22.1666666667 ~ 22.17 (This should be rounded)

Step-by-step explanation:

The mean formula is to add all the numbers and then divide by the quantity or how many numbers were listed.

25+31+12+38+12+15/6 = mean

All the numbers added up should equal 133

You need to divide the sum by 6 since that is how many numbers that are in your data set.

The Mean of the Data set is 22.1666666667 which is approximately 22.17
