Answer:
Number of small candles = 12
Number of large candles = 16
Step-by-step explanation:
Total candles = 28
x + y = 28 ---------------(I)
Cost of 'x' small candles = 4 *x = 4x
Cost of 'y' large candles = 6 *y = 6y
Total amount = $144
4x + 6y = 144 -------------(II)
Multiply equation (I) by (-4) and then add the equation. So, x will be eliminated and we can find the value of 'y'
(I) * (-4) -4x - 4y = -112
(II) 4x + 6y = 144 {Now, add}
2y = 32
y = 32/2
y = 16
Plug in y = 16 in equation (I)
x + 16 = 28
x = 28 - 16
x = 12
Answer:
small candles-x
large -y
144-4x=6y
28-x=y
28-y=x
(28-x)6+4x=144
168-6x+4x=114
-2x=-54
2x=54
x=27
27 small and 1 large

Cheyenne's car is in the shop, so she needs to rent a car for 4 days. The cost of a rental car is $24.99 per day, and she will be charged $0.18 per mile for every mile she drives over 200 miles. If she drives 300 miles and the sales tax she pays on the rental is 5.5%, how much will she pay for this rental?
Answer:
22.99
Step-by-step explanation:
Well, $24.99 dollars no matter how many miles. if she drove 200 miles, we will say that x represents miles driven. So, the cost will be $24.99+ $0.10x
to solve, substitute 20 for x.
$24.99 + $0.10(20)
$24.99 + $2
$24.99
Your answer is 22.99 dollars!

What is the volume of this rectangular prism?
cm
4/3 4/3 4/3
Answer:
64/27 cm³ or 2.37 cm³Step-by-step explanation:
volume of the rectangular prism = length x width x height
where:
length = 4/3 cm
width = 4/3 cm
height = 4/3 cm
plugin values into the formula:
volume of the rectangular prism = length x width x height
= 4/3 x 4/3 x 4/3
= 64/27 cm³ or 2.37 cm³
assume that the class has 80 students and that the examination period is 95 minutes in length. How many students do you expect will be unable to complete the exam in the allotted time
Answer:
Number of students successful= 75
Number of students not able to complete the exam in the allotted time= 5
Step-by-step explanation:
In this question the main part is missing .The given statement is the sub part of the problem .
Suppose the main part is
The time needed to complete a final examination in a particular college course is normally distributed with a mean of 80 minutes and a standard deviation of 10 minutes.
If the main part was given like this only then we could do the following calculations.
So from above the
Population mean = μ= 80
Population Standard deviation =σ= 10 mins
Sample mean = x`= 95
Sample size= n= 80
Now first we calculate the z= score
z= x`-μ/σ
z= 95-80/10= 1.5
From the z- table we find the P (z< 1.5)= 0.9332
Now we have to find the number of students who need to complete the exam in the allotted time
Number of students successful= np= 80 * 0.9332= 74.656= 75
Number of students not able to complete the exam in the allotted time= 80-75= 5
These answers are based on the main part supposed to be as added just to explain how it will be calculated.

- Lynn has two cats, Polly and Barney.
Lynn knows that Polly has a mass of 3 kg.
She estimates that Barney's mass is 3 times Polly's mass.
Work out an estimate of Barney's mass.
Answer:
9kg
Step-by-step explanation:
Because it is said that Polly's mass is 3kg but, Barney's mass is 3 times more kg than Polly.
So we multiply 3 (Polly's mass) multiplied by 3(cuz it is said three times more). So 3*3 = 9kg

If (p, q) is the solution to the system of equations, what is the value of q?
−16p − 2q = 100
p − 4q = 200
Answer:
The solution to the system of equations
p = 0q = -50Hence, the value of q = -50
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}-16p-2q=100\\ p-4q=200\end{bmatrix}[/tex]
solving to determine the value of q
Multiply p − 4q = 200 by 16: [tex]16p-64q=3200[/tex]
[tex]\begin{bmatrix}-16p-2q=100\\ 16p-64q=3200\end{bmatrix}[/tex]
so adding the equations
[tex]16p-64q=3200[/tex]
[tex]+[/tex]
[tex]\underline{-16p-2q=100}[/tex]
[tex]-66q=3300[/tex]
so
[tex]\begin{bmatrix}-16p-2q=100\\ -66q=3300\end{bmatrix}[/tex]
solve -66q = 3300
[tex]-66q=3300[/tex]
Divide both sides by -66
[tex]\frac{-66q}{-66}=\frac{3300}{-66}[/tex]
[tex]q=-50[/tex]
substituting q = -50 in −16p − 2q = 100
[tex]-16p-2\left(-50\right)=100[/tex]
[tex]-16p+100=100[/tex]
Subtract 100 from both sides
[tex]-16p+100-100=100-100[/tex]
Simplify
[tex]-16p=0[/tex]
Divide both sides by -16
[tex]\frac{-16p}{-16}=\frac{0}{-16}[/tex]
[tex]p=0[/tex]
Thus, the solution to the system of equations
p = 0q = -50Hence, the value of q = -50

The times a musician spends performing a rock song and a country song are approximately Normally distributed. The rock song has a mean time of 133 seconds with a standard deviation of 3.5 seconds, and the country song has a mean time of 126 seconds with a standard deviation of 3.3 seconds. If the musician randomly selects 4 times the rock song is played and 3 times the country song is played, what is the probability that the mean time for the rock song is less than the mean time for the country song?

Given m \| nm∥n, find the value of x.
Answer:
x=32
Step-by-step explanation:
If you do 2x-16+4x+4=180, then you should get 32.
The value of x is 32.
Given,
The m line is parallel with the n line.
We need to find the value of x.

AFD = CMF
AFM = CME
From the figure, we see that
2x - 16 + 4x + 4 = 180
6x - 12 = 180
6x = 180 + 12
6x = 192
x = 192/6
x = 32
Thus the value of x is 32.

(4+g)(-11)=121 pls show work whoever has answers first with right answer gets brainliest
Answer:
g = -15
Step-by-step explanation:
First, you are going to want to divide by -11 on both sides of the equation.
— (4 + g) (-11) / -11 = 121 / -11
— 4 + g = -11
(Note: dividing a positive number by a negative number will result in a negative number.)
Next, subtract 4 from both sides of the equation.
— 4 + g - 4 = -11 - 4
— g = -15
So, assuming you are looking for the value of g, you're answer is g = -15
The linear scale factor of two similar solids is given. Then the surface area and volume of the smaller figure are also given. Find the surface area and volume of the large figure.
Scale factor: 5:8
Surface area: 475
volume: 1125
Surface area: ?
volume: ?
Answer:
Surface area: 1216
Volume: 4608
Step-by-step explanation:
Scale factor: 5:8
This means that the dimensions of the larger figure are 8/5 of those in the smaller figure.
Surface area:
The surface area is found multiplying the square of the change(8/5) by the original surface area(475). So
[tex]S = (\frac{8}{5})^2 \times 475 = \frac{64}{25} \times 475 = 64 \times 19 = 1216[/tex]
Volume:
The volume is found multiplying the cube of the change(8/5) by the original volume(1125). So
[tex]S = (\frac{8}{5})^3 \times 1125 = \frac{512}{125} \times 1125 = 512 \times 9 = 4608[/tex]
