Marie went out for dinner with her friend. The dinner cost $24. Tax is 5% and Marcie wants to leave a
15% tip (she computed tip on the cost of dinner and tax.) How much will Marcie pay all together for
dinner?
Answers
Answer:
$28.83
Step-by-step explanation:
We will use: \(\frac{part}{whole}=\frac{percent}{100}\) and then use cross multiplication.
Let's solve the tax first.
We have:
tax (percent) = 5%
dinner cost (whole) = $24
we want to solve for "part". Lets set the equation up before we plug anything in
\(part*100=percent*whole\)
\(part = (\frac{percent*whole}{100} )\)
now plug everything in:
\(part = (\frac{5*24}{100} )\)
part = $1.20
what does this mean?
Well it actually means $1.20 is the amount of money we pay in tax.
So we add that to our total.
24 + 1.20 = $25.20
Next we will do the tip. We will use the same equation as above:
tip (percent) = 15%
dinner cost (whole) = $25.20
plug everything in:
\(part = (\frac{15*24.2}{100} )\)
part = $3.63
That means we pay an extra 3.63 as a tip. So lets add that to our dinner cost:
25.20 + 3.63 = $28.83
So we end up paying $28.83 for our dinner in total.

Answers
Answer:Median; because the data is not symmetric and there are outliers.
Step-by-step explanation:We know that a median is a central tendency of a data and it best represents the given data set.
From the given information we see that the data is skewed to the right since most of the data points takes the higher value and the data is not symmetric as it is skewed.

Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
Answers
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Q1) 80% of a dog's mass is equal to 24% of the mass of a lion. If the mass of the lion is 105 kg more than the mass of the dog, find the total mass of the dog and the lion.
Answers
We are given that 80% of the dog's mass is equal to 24% of the lion's mass. Mathematically, this can be expressed as:
0.80D = 0.24L
We are also given that the mass of the lion is 105 kg more than the mass of the dog:
L = D + 105
We can use these two equations to find the values of D and L.
Substituting the value of L from the second equation into the first equation:
0.80D = 0.24(D + 105)
Now, let's solve for D:
0.80D = 0.24D + 0.24(105)
0.80D - 0.24D = 25.2
0.56D = 25.2
D = 25.2 / 0.56
D ≈ 45
Now that we have the value of D, we can find the value of L by substituting it back into the second equation:
L = 45 + 105
L = 150
Therefore, the total mass of the dog and the lion is:
D + L = 45 + 150 = 195 kg
So, the total mass of the dog and the lion is 195 kg.

4.35 and we multiply it by 1000

The miles on Connor's old car were 39 times greater than the miles on his new car.
What is the distance?A mathematical number known as distance measures "how much ground an object has traveled" while moving. Distance is defined as the product of speed and time.
To solve this problem, we need to divide the number of miles on Connor's old car by the number of miles on his new car and round the result to the nearest whole number.
The number of miles on Connor's old car is 1.67 x 10⁵ miles and the number of miles on his new car is 4.35 x 10³ miles, so the number of times greater the miles on his old car are than his new car is:
(1.67 x 10⁵ miles) / (4.35 x 10³ miles) = 38.6
Rounded to the nearest whole number, this is 39.
Therefore, the miles on Connor's old car were 39 times greater than the miles on his new car.

2. One angle of a triangle measures 10 degrees more than the second. The measure of the third angle is twice the sum of the measures of the first two angles. Find the measure of each angle. [Hint: the sum of the three angles in a triangle equals 180°.] PLEASE SHOW YOUR WORK I WILL MAKE BRAINLIST PLEASE!!!!!!!
Answers
Answer:
first angle = 25 degrees
Second angle = 35 degrees
Third side = 120/degrees
Step-by-step explanation:
Let the size of the second angle be x degrees.
One angle of a triangle measures 10 degrees more than the second. This means that the size of the first angle is ( x+ 10 )degrees.
The measure of the third angle is twice the sum of the measures of the first two angles. This means that The third angle = 2( first angle + second angle). So the size of each angle is
First angle (x + 10) degrees
Second angle = x degrees
Third angle = 2(x + 10 + x) = (4x + 20) degrees
Sum of angles in a triangle = 180 degrees. Therefore, x + 10 + x + 4x + 20 = 180 degrees 6x + 30 = 180
6x = 180 - 30 = 150
x = 150/6 = 25 degrees
First angle = x + 10 = 25 +10 = 35
Third angle = 4x + 20 = 4 × 25 + 20
= 100+ 20 = 120 degrees
Hope this helps
Answer:25(1st angle),35(2nd angle),120(3rd angle)
Step-by-step explanation: (/ stands for divide)
180/6=30 (sum of angles/total units=value of one unit, third angle is 4 units as it is twice the sum of first two angles)
30x4=120 (value of unitxnumber of units of 3rd angle=3rd angle)
30x2=60 (value of unitxfirst angle+second angle total units=value of 1st angle+2nd angle)
(60-10)/2=25(1st angle)
25+10=35(2nd angle)

4a2. Sample 2 Mean: $5650; Sample 2 Median: $5600.
4b. The monthly cost of living is more expensive for a married couple w/ 1 child than for a single person.
Step-by-step explanation:
2a./2b.
In order to find the mean absolute deviation, we need to first find the mean.
(21 + 45 + 21 + 14 + 21 + 28 + 24 + 14 + 24 + 28)/10
(66 + 35 + 49 + 38 + 52)/10
(101 + 87 + 52)/10
(101 + 139)/10
240/10
The mean of this set is 24.
Now for the deviation.
21 - 24 = -345 - 24 = 2114 - 24 = -1028 - 24 = 424 - 24 = 0For the mean absolute deviation, divide the combined value of the 10 deviation values from before (in absolute value) by 10.
(|-3| + 21 + |-3| + |-10| + |-3| + 4 + |-10| + 4)/10
(3 + 25 + 3 + 10 + 3 + 10 + 4)/10
(28 + 13 + 13 + 4)/10
(41 + 17)/10
58/10
The mean absolute deviation is 5.8. That interpreted would be like this: A score, on average, is 5.8 points away from the average score.
2c.
What I'll do here is the following: subtract 45 from 240, and then subtract 21 from the mean deviations. In both cases, I will now divide by 9.
(240 - 45)/9
195/9
65/3
The mean of the set (without 45) is now 21 2/3.
(58 - 21)/9
37/9
The new mean absolute deviation is 4 1/9, which rounds to 4.1. That's 1.7 points nearer to the average than originally.
So, without 45 as one of the scores, the M.A.D. decreases by about 2. That interpreted would be like this: The scores are about 2 points nearer to the average than before.
4a./4b.
First, I'll find the mean for sample one.
(1800 + 2000 + 2200 + 2300 + 2500 + 3000)/6
(3800 + 4500 + 5500)/6
(8300 + 5500)/6
13800/6
The mean for sample one is $2,300/month.
Now for the median for sample one. Since there are 6 values, add the two middle values and divide by 2.
(2200 + 2300)/2
4500/2
The median for sample one is $2,250/month.
Now for the mean & median for sample two.
Mean:
(5400 + 5500 + 5600 + 5600 + 5800 + 6000)/6
(10900 + 11200 + 11800)/6
(22100 + 11800)/6
33900/6
The mean for sample two is $5,650/month.
Median:
Again, there are 6 values. However, this time they are the same, so there is no need to divide. The median for sample two is $5,600/month.
Looking at the data, the mean & median for sample was larger than sample one. Thus, I can conclude the following: The monthly cost of living is more expensive for a married couple w/ 1 child than for a single person.
