All you have to do is take $32.10 and then subtract 1.80. So it should look like 32.10 - $1.80. The answer should be 30.30
Sammy ate lunch and wanted to leave her waitress a 15% tip. Her meal costs $8. 95. How much money should Sammy leave for the tip?
Answer:
Sammy left a tip of $1.34
Step-by-step explanation:
Convert 15% into a decimal by dividing by 100%
15% ÷ 100% = 0.15
Multiply it to the meal cost
$8.95 × 0.15 = $1.3425
Rounding to the nearest cent, Sammy should leave a tip of $1.34.
I hope this helps you!
Have a wonderful day!

Two angles are supplementary. One measures (3x) degrees and the other measures 51 degrees.
a. Write an equation to show the relationship between the two angles and solve for the value of x.
b. Find the measure of both angles
Answer:
a. 3x +51=180
x=43
b. 3(43)+51 =180 51 degrees; 129 degrees
Step-by-step explanation:
3x +51 =180
3x=180-51
3x=129
x=43
brandon took a 50-question exam worth a total of 160 points. There were x two-point questions and y five point questions. How many of each type of question were on the exam?
Answer:
[tex]\large{\boxed{\sf x = 30 , \ y \ = \ 20}}[/tex]
Step-by-step explanation:
Here it is given that Brandon took a 50 question exam worth of 160points . So here the sum of 2 point and 5 point question is 50. So ,
[tex]\sf\qquad\longrightarrow x + y = 50.....(i)[/tex]
Again the maximum marks for the exam is 160 . Therefore ,
[tex]\sf\qquad\longrightarrow 2x + 5y = 160 ..... (ii) [/tex]
Multiply equation (i) with 5 ,
[tex]\sf\qquad\longrightarrow 5x + 5y = 250 [/tex]
Subtract equation (ii) and (i) ,
[tex]\sf\qquad\longrightarrow 5x - 2x = 250-160\\[/tex]
[tex]\sf\qquad\longrightarrow 3x = 90\\[/tex]
[tex]\sf\qquad\longrightarrow x =\dfrac{90}{3}\\[/tex]
[tex]\sf\qquad\longrightarrow \pink{ x = 30} [/tex]
Substitute this value in (i) ,
[tex]\sf\qquad\longrightarrow y = 50-x \\ [/tex]
[tex]\sf\qquad\longrightarrow y= 50-30\\ [/tex]
[tex]\sf\qquad\longrightarrow \pink{ y = 20} [/tex]
Hence ,
No. of 2 point question = 30No. of 5 point question = 20If

What is the area of the semicircle window shown above?
Solution:
We know that the diameter of the semi-circle is 30 inches. Before we use the formula, let's find the radius of the semi-circle.
⇒ Diameter = 2(Radius)
⇒ 30 inches = 2(Radius)
⇒ Radius = 30/2 = 15 inches
The area of the circle is πr², but we need to find the area of the semi-circle. A semi-circle is basically half of a circle. This means that the area of a semi-circle is πr²/2. Now, let's solve for the area of the semi-circle.
⇒ πr²/2 = Area of semi-circle
⇒ (22/7)(15²)/2
⇒ (22/7)(225)/2
⇒ (22/7)(112.5)
⇒ 22/7 × 112.5
⇒ 2475/7 in²
Thus, the area of the semi-circle is 2475/7 in².

Answer:
x = 9 , y = - 3
Step-by-step explanation:
(1)
8.88 = 4.44(x - 7) ← divide both sides by 4.44
2 = x - 7 ( add 7 to both sides )
9 = x
(2)
5(y + [tex]\frac{2}{5}[/tex] ) = - 13 ← distribute parenthesis by 5
5y + 2 = - 13 ( subtract 2 from both sides )
5y = - 15 ( divide both sides by 5 )

Answer:
10
Step-by-step explanation:
Hello! So over here, when they use the word "directly," they're hinting that they want you to use direct proportions.
You know that the mass and the weight directly correlate, which means that they are direct proportions.
We are given a comparison of mass to weight as an example. Mass:Weight = 8:64
If we simplify that ratio, we get 1:8. The ratio of Mass:Weight is 1:8. In other words, the mass is 8 times less than the weight.
We are given our new weight of 80. Since mass is 8 times less than weight, we do 80/8 which equals 10.

To get to school, 19/50 of the students ride in the family vehicle, 5 out of 12 students ride on the school bus, and 0.12 of the students ride a bike. Order the types of transportation students use to get to school from least to greatest.
Answer:
0.12, 19/50, 5 out of 12
0.12 (least). 19/50 (second least), and 5 out of 12 (greatest)
Step-by-step explanation:
If you convert them all to decimals by dividing it will be much easier to solve.
19/50 = 0.38
5 out of 12 is 5/12 = 0.41

does y-2=2-x have a negative slope
Answer:
Yes
Step-by-step explanation:
Simplifying the equation, you get y= -x+4
The slope is -1, from -x, so the slope is negative
Feel free to comment if you have any questions! Your welcome btw :D
Answer:
Step-by-step explanation:
Let us solve for y and get the equation format y = mx + b where m is the slope's value.
We get y = -x+4. Since m is negative, then the function does have a negative slope.

Find sin 2theta if theta is in the first quadrant and tan theta=40/9. PLEASE HELP. No links
well, we know that angle θ is in the I Quadrant, namely that sine as well as cosine are both positive and most likely 2θ is in the II Quadrant, where sine is positive, so
[tex]tan(\theta )=\cfrac{\stackrel{opposite}{40}}{\underset{adjacent}{9}}\qquad \textit{now let's find the \underline{hypotenuse}} \\\\\\ \textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies c=\sqrt{a^2+b^2} \qquad \begin{cases} c=hypotenuse\\ a=adjacent\\ b=opposite\\ \end{cases} \\\\\\ c=\sqrt{9^2+40^2}\implies c=\sqrt{1681}\implies c=41 \\\\[-0.35em] ~\dotfill[/tex]

A date in the month of June is selected, then a letter from the word SPERSTAR is chosen. what is the probability of getting a multiple of 8 then S?
Answer:
1/40
Step-by-step explanation:
the chance of getting a multiple of 8 in June:
there are 3 multiples of 8 in June so that makes the chance 3/30 or 1/10
the chance of getting an S in Superstar:
there are 2 's' in Superstar and 8 letters total so the chances are 2/8 or 1/4
to get the chance we just need to multiply 1/10 by 1/4 and we get 1/40

If you run 3 meters per second to the left, where will you be 4 seconds after you pass zero?
Answer:
12 meters to the left, or -12
Step-by-step explanation:
3 meters per second for 4 seconds
Meaning it's 3 x 4
3 x 4 = 12, so therefore it's -12 meters or just 12 meters to the left.
Answer:
12 meters to the left of your starting point.
Step-by-step explanation:
You start at 0 meters. You then start running to the left with an acceleration of 3 m/s to the left. After each seconds, you are 3 more meters to the left.
So
3 m/s * 4 s = 12 m to the left.
Hence, the answer in 12 meters to the left.

Rachel has 10 sweets in a bag.
7 of the sweets are yellow.
3 of the sweets are red.
Rachel takes random sweets from the bag, one at a time, until she gets a red sweet.
She does not replace the sweets that she takes from the bag.
Rachel stops as soon as she gets a red sweet.
Work out the probability that Rachel takes no more than three sweets from the bag.
Using it's concept, it is found that there is a 0.713 = 71.3% probability that Rachel takes no more than three sweets from the bag.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, we have that:
One sweet, the probability is 3/10.For two, the probability is 7/10 then 3/9.For three, it is 7/10 then 6/9 then 3/8.So:
[tex]p = \frac{3}{10} + \frac{7}{10} \times \frac{3}{9} + \frac{7}{10} \times \frac{6}{9} \times \frac{3}{8} = 0.713[/tex]
0.713 = 71.3% probability that Rachel takes no more than three sweets from the bag.
