Answer:

28º

Step-by-step explanation:

CAT = 90 - 62

CAT = 28º

Answer:

60

Step-by-step explanation:

10×2=20÷2=10×2=20 goes for the two top ones

20×2=40÷2=20×2=40 goes for the two bottom ones

40+20=60 is the answer

Answer:

60ft^2

Step-by-step explanation:

Split the area into two large triangles, the right and the left.

The base for the triangle is 10ft+20ft =30ft and we know the height is 2.

Since A=bh*1/2, A = 30*2*1/2. This equals 30. since there are two of these large triangles and they are equal, just multiply the area by 30.

Answer:

Part A= 19.2 Part B= 27.2

Step-by-step explanation:

4+8=12 divided by 1.25 equals 19.2

Width= 4+6=10 divided by 1.25=8

19.2+8= 27.2 is the total area

Hope this is right (:

Answer:

A. 19.2 Feet

B. 307.2 Feet

Step-by-step explanation:

A. First you divide 2 feet by 1.25 inches to figure out how much feet per inch.

2/1.25=1.6 feet

Meaning that 1 inch is 1.6 feet or 1 inch=1.6 feet

After that you add the length of 4 inches and 8 inches which equals 12 inches.

4+8=12 inches

After that you multiply 12 by 1.6

12*1.6=19.2

Meaning that the actual length is 19.2 feet

B. Once you find the length you add 4 inches and 6 inches which equals 10 inches.

Multiply 10 by 1.6

10*1.6=16 feet

After that to find the area you multiply 16 and 19.2.

16*19.2=307.2 feet

Answer:

240 people

Step-by-step explanation:

[tex]\frac{60}{25} =\frac{x}{100}[/tex] (x represents people)

60×100= 6000 , 25 × [tex]x[/tex] = 25[tex]x[/tex]

[tex]\frac{25x}{25x}=x[/tex]        [tex]\frac{6000}{25x} = 240[/tex]

x=240

Answer:

(using substitution to solve the problem)

x=y-3

2x+y=12

2(y-3)+y=12

2y-6+y=12

3y=18

y=6

y=6

x=6-3

= (3, 6)

Step-by-step explanation:

using substitution, substitute the x in the second equation to y-3, to find the value of y. after that distribute the 2 into the parenthesis and collect like terms. once you simplify, you have the value of y, so substitute the value of y into the first equation to find x. once you have both values put them in the ordered pair form and you're done.

Answer:

Do you have a picture of the work hhh

Step-by-step explanation:

Given:

In circle D, the measure of angle ADC is 108 degrees.

To find:

The measure of angle ABC.

Solution:

Central angle theorem: According to this theorem, the measure of central angle of an arc is twice of the measure of inscribed angle on that arc.

Using the Central angle theorem, we get

[tex]m\angle ADC=2\times m\angle ABC[/tex]

[tex]108^\circ=2\times m\angle ABC[/tex]

[tex]\dfrac{108^\circ}{2}= m\angle ABC[/tex]

[tex]54^\circ= m\angle ABC[/tex]

Therefore, the measure of angle ABC is 54 degrees.

Answer:

75.4 ft³

Step-by-step explanation:

Volume of a cone = πr²h/3

π = 3.14

radius, r = diameter / 2

= 6ft/2

= 3 ft

Height, h = 8 ft

Volume of a cone = πr²h/3

= (3.14 * (3)² * 8) / 3

= (3.14 * 9 * 8) / 3

= 226.08 / 3

= 75.36

Volume of a cone = 75.36 ft³

Approximately to the nearest tenth = 75.4 ft³

Answer:

Down below.

Step-by-step explanation:

A=2(wl+hl+hw)

A=2(4*5+5*7+7*4)

A=2(20+35+28)

A=2(83)

A=166mm^2

Answer:

hello yes from Mr Ching class the answer would just be 1271.7 because the volume of a cone is 1/3 of the volume of a cylinder of the same dimensions

Step-by-step explanation:

multiply cone volume by 1/3

Answer:

103 & 77 degrees

Step-by-step explanation:

Supplements add up to 180 degrees.

I started at 90 & did:

90 + 13 = 103

(Because 13 * 2 is 26, but if you subtract 26 then the supplement will be 52 away & not 26)

180 - 103 = 77

103 - 77 = 26

Hope this helped. :)

Answer:

-4 is less than 17 and the "less than" symbol is <. however, this situation can also be expressed by -4 being "less than or equal to" 17 (this symbol is < with a line underneath it)

-4 < 17 OR -14 "less than or equal to" 17
