Answer:

  60°

Step-by-step explanation:

  60 × 1° = 60°

The angle measure is 60°.

Answer:

142 degrees

Step-by-step explanation:

The sum of angle in a quadrilateral is 360 degrees

33 + 20 + 165 + X =360

53 + 165 + X = 360

218 + X = 360

X = 360 - 218

X = 142

Hence the size of angle X is 142 degrees

Answer: (-5,1)

Step-by-step explanation: that should be right

= option J

area of figure = 1/2 × 6× 4 + 8×6 + 3.14× 9/2

= 12+ 48 + 3.14× 4.5

= 60+ 14.13

= 74.13 cm²

option J

Answer:

h = 34

Step-by-step explanation:

64=h+30

Step 1: Flip the equation.

h+30=64

Step 2: Subtract 30 from both sides.

h+30−30=64−30

h=34

Step-by-step explanation:

d+5-f

Plug in the values of d and f

(16)+5-(-18)

Then simplify (Don't forget that since theres a double negative, that changes to a positive.)

Answer:

30

Step-by-step explanation:

To calculate the mean, add up all the numbers in the data and divide the sum by the number of numbers in the data.

(18+36+24+36+30+36)/6 = 30.

Answer:

30

Step-by-step explanation:

To find mean, add up all the numbers, then divide by how many numbers there are:

18 + 36 + 24 + 36 + 30 + 36/6

180/6 = 30

¿*=£×**€×¿¿==£÷€=4÷54

Step-by-step explanation:

The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal or initial amount of money invested.

R represents interest rate

T represents time

Considering the investment on account A,

I = $6.94

R = 3.7%

T = 9 months = 9/12 = 0.75 years

6.94 = (P × 3.7 × 0.75)/100 = 0.02775P

P = 6.94/0.02775 = $250

Considering the investment on account B,

I = $13.80

R = 2.3%

T = 18 months = 18/12 = 1.5 years

13.8 = (P × 2.3 × 1.5)/100 = 0.0345P

P = 13.8/0.0345 = $400

To determine the account that earned more interest in the first month,

250/9 = $27.8

400/18 = $22.2

Account A earned you the most interest the first​ month because $27.8 is higher than $22.2

Answer:

A) Erin has lost 250 points.

Step-by-step explanation:

The reason A is correct is because Erin has -250 points, which means he went down or lost them.

Answer:

x=4

Step-by-step explanation:

you have to get x on one side so x=4

Answer:

x=4

Step-by-step explanation:

combine the like terms beside eachother so it would be

6x-x=24-4

5x=20

then move the 5 and divide

x=20/5

x=4

Step-by-step explanation:

Answer:

$16.20

Step-by-step explanation:

Bill: $54.00

Tip: 20%

People: 4

To figure out 10% of the bill, you need to move the decimal point over to the left one place: $5.40

10%: $5.40

5.40 times 2 = $10.80

54.00 + 10.80 = 64.80

Grand Total= $64.80

Since there are 4 people, we need to divide by 4:

64.80 divided by 4 = $16.20

Answer:

8units²

Step-by-step explanation:

Area of the trapezoid = 1/2(a+b)h

a and b are the opposite sides

h is the height

Take a square as 1 unit

a = 1 unit

b = 3 units

height h = 4 units

Substitute

A = 1/2(1+3)*4

A = 1/2 * 4 * 4

A = 16/2

A = 8units²

Hence the area of the trapezoid is 8units²

Right format of question:

Plot two points that are 7 units from Point D and also share the same x-coordinate as Point D.

Answer:

[tex]D' = (-4,-6)[/tex] and [tex]D' = (-4,8)[/tex]

Step-by-step explanation:

Given

[tex]D(x,y) = (-4,1)[/tex]

Required

Determine a point 7 points from D and in the same x coordinate

Represent this point with D'.

From the requirement of the question, D' has two possible values and these values are:

[tex]D' = D(x,y-7)[/tex] ----> 7 units down and

[tex]D' = D(x,y+7)[/tex] ----> 7 units up

Substitute values for x and y in [tex]D' = D(x,y-7)[/tex] and [tex]D' = D(x,y+7)[/tex]

So, we have:

[tex]D' = D(x,y-7)[/tex]

[tex]D' = (-4,1 - 7)[/tex]

[tex]D' = (-4,-6)[/tex]

[tex]D' = D(x,y+7)[/tex]

[tex]D' = (-4,1+7)[/tex]

[tex]D' = (-4,8)[/tex]

Answer:

B. 1.5

Step-by-step explanation:

12/8 = 1.5

Answer: 75.75°

Step-by-step explanation:

Sine is the opposite of the angle divided by the hypotenuse. The opposite side of the angle is 12.6 and the hypotenuse is 13.

sin(Ф) = 12.6/13

Take the inverse sine of both sides, this requires a calculator.

Ф = 75.75°

Answer:

See below, please!

Step-by-step explanation:

There are infinite number of ratios equivalent to 3:8 because both numbers can be multiplied by a common number or divided by a common number.

For example, 9:24 would still be equivalent to 3:8 because the common number in our case is 3. See what I mean?

Answer: 20 g butter, 10 g sugar, 30 g flour

Step-by-step explanation: First off, if we look at 3 and 18, you notice that three is a factor or 18, going into the number 6 times.

So, if you are making 6 times less of the original amount, divide each measurement by six to give you your answer.

120/6 = 20

60/6 = 10

180/6 = 30
