Your restaurant bill comes to $46.27. Estimate a 10% tip.

Answers

If the bill of the restaurant comes to $46.27 then the tip of 10% is equal to $4.627.

What is percentage?

Percentage is number or ratio that is expressed as a fraction of 100. It is shown by % sign. It shows some quantity over other quantity. The number which shows the percentage is the number in the quantity itself.

How to calculate percentage?

We have been given that the bill of the restaurant comes to $46.27 and 10% is the tip. We have to calculate the tip.

Tip=Bill*10/100

=46.27*10/100

=4627*10/100*100

=46270/10000

=$4.627

Hence if the bill of the restaurant is $46.27 then tip will be $4.627.

Answer:15

Step-by-step explanation:

Answer:

The answer is B) 75

Step-by-step explanation:

The angle shown is a 90-degree angle. Therefore if the other angle is 15 degrees, that means that all we have to do is subtract 15 from 90.

90-15= 75 which means the angle known as x is a 75-degree angle.

The graph shows the relationship between the distance a car is driven and the number of gallons of gasoline used. Identify the value in d in the point (1, d). What does that point represent?

A. d=25; the unit rate is 25 miles per gallon
B. d=25; the unit rate is 25 gallons per mile
C. d=50; the unit rate is 50 miles per gallon
D. d=50; the unit rate is 50 gallons per mile

Answers

Answer:

A. d = 25; the unit rate is 25 miles per gallon

Step-by-step explanation:

The point (1, d) on the graph represents (x, y), where,

x = gasoline used = 1 gallon

y = distance = d = 25 miles

That is, (1, d) represents when x = 1, y = 25.

Thus, (1, 25) is the unit rate which is 25miles per gallon.

Question 1 A)

What side length did Mr.Freeman measure the second time?

Answers

D. 2.33

The number that has 1/10th the value of 0.3 is 0.03.

Each place value to the left of a decimal place is 10x the value of the one closer to the decimal, and each place value to the right of a decimal is 1/10th the value of the place closer.

Answer:  D) 2.33 meters

==========================================================

Explanation:

The hundredths digit is 1/10 of the tenths digit. Because of this, the tenths and hundredths digit must be the same digit.

Only choice D fits the description.

The digit in the tenths place represents the value 0.3

Taking 1/10th of this leads to (1/10)*0.3 = 0.1*0.3 = 0.03

So the hundredths place represents the value 0.03

Note that,

2 + 0.3 + 0.03 = 2.33 meters

Find the missing side lengths. Leave your answers as radicals in simplest form.

Answers

Answer:

A. a = √2

b = √2

Step-by-step explanation:

Apply trigonometric function to find a and b:

Reference angle = 45°

Hypotenuse = 2

Opposite side = a

Adjacent side = b

✔️Apply SOH to find a, which is:

Sin 45 = Opp/Hyp

Sin 45 = a/2

2*Sin 45 = a

2*1/√2 = a (sin 45 = 1√2)

2/√2 = a

Rationalize

(2*√2)/(√2*√2) = a

2√2/2 = a

√2 = a

a = √2

✔️Apply CAH to find b, which is:

Cos 45 = Adjacent/Hypotenuse

Cos 45 = b/2

2*Cos 45 = b

2*1/√2 = b (Cos 45 = 1√2)

2/√2 = b

Rationalize

2√2/2 = b

√2 = b

b = √2

Solve the equation. Show the process, not just an answer. 6.EE.7
1) 4k = 24
2) 34 + h = 60
3) 1/5x = 30
4) m-42 = 85

Answers

Isolate the variable, note the equal sign, what you do to one side, you do to the other.

1) 4k = 24

Isolate the variable, k. Divide 4 from both sides of the equation:

(4k)/4 = (24)/4

k = 24/4

k = 6

2) 34 + h = 60

Isolate the variable, h. Subtract 34 from both sides of the equation:

34 (-34) + h = 60 (-34)

h = 60 - 34

h = 26

3) 1/5x = 30

Isolate the variable, x. Multiply 5 to both sides of the equation:

(5) * (1/5)x = (30) * (5)

x = 30 * 5

x = 150

4) m - 42 = 85

Isolate the variable, m. Add 42 to both sides of the equation:

m- 42 (+42) = 85 (+42)

m = 85 + 42

m = 127

v=10.1

Step-by-step explanation:

v= 4.5 + at  -------> equation 1

given

a=1.6

t=3.5

so we will plug in the value in equation 1

v = 4.5 + (1.6 x 3.5)

v = 4.5 + 5.6

v = 10.1
