Answers

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]

Solve 64 = h + 30.
K=?

Answers

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

Assuming you meant “h =?” instead of “K=?”. In that case,
h = 34.

To find this answer, you just subtract 30 from 64, isolating h on it’s own side. Or imagine the problem arranged “h + 30 = 64.”

Someone pls help me wit this I’m so confused

Answers

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°

Amy and three of her friends went to lunch. The total bill was $54.00. If they wanted to leave a 20% tip how
much more is added tot he bill?
If the girls split the bill evenly, how much does Amy pay?

Answers

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

Work out the size of angle
X.
X Х
33°
20°
165°

Answers

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

Which is a better deal on a $10 item:

50% off or 10% off and then another 40% off? Explain your answer.

Answers

50% off. You only have to pay $5. If you do 10% off one time you have to pay $9 and then the next time you get 40% off, you’d have to pay $6.

Unless I completely misunderstood, 50% should be better. If it’s 40% off + 10% then it will be 50% and therefore both of them are equal deals and both good.

This recipe makes 18 shortbread fingers.
Rose follows this recipe, but only wants to make 3 fingers.
How much of each ingredient does she need?

Recipe: Makes 18
120 g butter
60 g sugar
180 g flour

Answers

(I don't know if this is the method you are supposed to use, but I believe you will still get the same answer!)

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

20g butter
10g sugar
30g flour
