Answer:

5625π cm²

Step-by-step explanation:

Radius = 150 / 2 = 75 cm

Area = πr² = π(75)² = 5625π cm²

Answer: 17662.5 (I used 3.14 instead of the regular pi but if you need to use pi the answer would be 17671.4587)

Step-by-step explanation:

First, you grab the diameter then divide that by 2 (that gives you the radius of the circle) Then, multiple 75² * 3.14 (or pi) to give you the answer!

Hope this helps! Good luck!

Your answer is -6

Step-by-step explanation:

Hope this helps :3

Answer:

The answer to the problem is -6.

Answer:

Question 10.

angle 1 = 137°

angle 2 = 43°

angle 3 = 137°

reasoning - vertically opposite angles are equal, and angles on a point total to 360 degrees

Question 11.

a) Vertical: I dont know sorry :(

b) Complementary: ∠c and ∠b

c) Suplementary: ∠c and ∠d

d) All adjacent: I dont know sorry :(

e) Find values of all angles, if angle c is 30°: ∠a = 90°, ∠b = 60°, ∠c = 30°, ∠d = 150°, ∠e = 30°

hope this helps :)

Answer:

y-intercept: -3.

Slope:7/5

Step-by-step explanation: Y-intercept: The line crosses the y-axis at y=-3.

Slope: If you start from the point on the y-axis, -3, and count up 7 units, you reach 4 and then count right 5 units to reach a part of the line which touches a point. You go up 7 and go right 5 units. Therefore, the slope is 7/5. You go up, or rise, 7 units, and go right, or run, 5 units.

hi there user! Looks like your looking for help, so Mizuki came here to help you!

the answer is:

m is 2/3

The whole work I did:

m + 4 ÷ 3 = 2

m + 4/3 = 2

m + 4/3 - 4/3 = 2 - 4/3

m = 6/3 - 4/3

m = 2/3

Anyways hope this helped! qwq

M is -41. If you add 43 to -41, your result will be 2. A number line would help you, too.

Answer:

mean = 85.5

median = 90

mode = 95

range = 35

Step-by-step explanation:

First arrange the data in ascending order:

60 75 75 90 90 95 95 95 95

Mean is the average number found by adding all of the numbers together and dividing by the number of terms in the set.

[tex] = \frac{60 + 75 + 75 + 90 + 90 + 95 + 95 + 95 + 95}{9} [/tex]

[tex] = \frac{770}{9} [/tex]

=85.5

Median is the middle number of the set: (9+1) ÷2 = 5th term.

60 75 75 90 90 95 95 95 95

therefore the median is 90

The mode is the number that is repeated more often than any other, so 95 is the mode.

The range = the largest value - the smallest value

= L-S = 95-50

= 35

Therefore the range is 35.

Answer:

27-degrees

Step-by-step explanation:

these are vertical angles which are equal to each other *congruent

39 + k = 66 --> *subtract 39 from both sides*

k = 27

Answer:

27°

Step-by-step explanation:

Remember the angle opposite of another angle in two straight lines are equal

So 66=39+k

Then put k by itself by subtracting 39 from both sides

66-39=k

k=27°

Step-by-step explanation:

inequalities are stuff like 4x > 2x or 1 < 2

Answer:

the two balls are yellow and green, in either order.

Step-by-step explanation:

P(Y) = 5/10 = 1/2

P(R) = 3/10

P(G) = 2/10

Since the only combination that makes a product of 1/10, so

P(Y)*P(G) = (5//10) * (2/10) = 10/100 = 1/10

So the two balls are yellow and green, in either order.

Answer:

how much km was left

Step-by-step explanation:

his whole journey length would be if u add both km

Answer:

What u said dosent make sense lol

Answer:

Step-by-step explanation:

4.

a)

P = 2width + 2length

8x = 2x + 2 length; 8x-2x = 2 length; 6x=2 length

length = 3x

b)

sides= 1/4 of 3x = 3x/4

perimeter of square = 4* side = 4*3x/4 = 3x

c)

x= 4

P rectangle =8x= 8*4= 32

P square = 3x = 3*4 = 12

32-12 = 20 cm greater is the P rectangle than P of square

d)

A rectangle = 2x*x = 2*4*4 = 32

A square =(3x/4)² = (3*4/4)² = 9

32-9 = 23 cm² greater is the A rectangle than A of square

4Comic+1 Nonfiction

4comic = 8y so 1 comic = 2y

1 nonfiction = (3+7y)+ 2y

a)

1 nonfiction = 7y+2y+3 = 9y+3

b)

total= 8y+9y+3 = 17y+3

if y=4

total = 17*4 +3  = $71
