On Friday, a local hamburger shop sold a combined total of 390 hamburgers and cheeseburgers. The number of cheeseburgers sold was two times the number of hamburgers sold. How many hamburgers were sold on Friday?
Answer:
There were 130 hamburgers sold on Friday
Step-by-step explanation:
Assume that the number of hamburgers sold is x
∵ The number hamburgers sold = x
∵ The number of cheeseburgers sold was two times the number of
hamburgers sold
∴ The number of cheeseburgers sold = 2x
∵ On Friday, the shop sold a combined total of 390 hamburgers and
cheeseburgers
→ Add x and 2x, then equate the sum by 390
∴ x + 2x = 390
→ Add the like terms
∴ 3x = 390
→ Divide both sides by 3
∵ [tex]\frac{3x}{3}[/tex] = [tex]\frac{390}{3}[/tex]
∴ x = 130
∵ x represents the number of hamburgers
∴ There were 130 hamburgers sold on Friday

y = mx + b Ax + By = C
y = -3/4x + 2 y = -3/4x + 2 add 3/4x to both sides
3/4x + y = 2 multiply by 4
3x + 4y = 8
What is the solution to 8x-3(2x-4)= 3(x-6
)
Answer:
x = 30
Step-by-step explanation:
8x - 3(2x - 4) = 3(x - 6)
Distribute te -3 on the left, and the 3 on the right
8x - 3(2x - 4) = 3(x - 6)
8x - 6x + 12 = 3x - 18
Simplify
8x - 6x + 12 = 3x - 18
2x + 12 = 3x - 18
Inverse operations
2x + 12 = 3x - 18
-2x -2x
12 = x - 18
+18 +18
30 = x
Find the vector that has the same direction as 3, 2, −6 but has length 2.
Answer:
The vector is [tex]\vec r = \left(\frac{6}{7},\frac{4}{7},-\frac{12}{7}\right)[/tex].
Step-by-step explanation:
We can determine the equivalent vector ([tex]\vec r[/tex]), dimensionless, by means of the following formula:
[tex]\vec r = \frac{\vec u}{\|\vec u\|} \cdot \|\vec r\|[/tex] (1)
Where:
[tex]\vec u[/tex] - Original vector, dimensionless.
[tex]\|\vec u\|[/tex] - Norm of the original vector, dimensionless.
[tex]\|\vec r\|[/tex] - Norm of the new vector, dimensionless.
The norm of the original vector is determined by the following definition:
[tex]\|\vec u\| = \sqrt{\vec u\,\bullet \,\vec u}[/tex] (2)
If we know that [tex]\vec u = (3, 2, -6)[/tex], then the norm of the original vector is:
[tex]\|\vec u\| = \sqrt{(3)\cdot (3)+(2)\cdot (2)+(-6)\cdot (-6)}[/tex]
[tex]\|\vec u\| = 7[/tex]
If we know that [tex]\|\vec r\| = 2[/tex], then the new vector is:
[tex]\vec r = \frac{2}{7}\cdot (3,2,-6)[/tex]
[tex]\vec r = \left(\frac{6}{7},\frac{4}{7},-\frac{12}{7}\right)[/tex]
The vector is [tex]\vec r = \left(\frac{6}{7},\frac{4}{7},-\frac{12}{7}\right)[/tex].

Answer:
[tex]Volume = 2000\ in^3[/tex]
Step-by-step explanation:
Given
Dimension: 10in by 20in by 10in
Required
Determine the capacity of the aquarium
This question implies that, we calculate the volume of the prism and this is calculated by multiplying the dimensions of the aquarium. i.e.
[tex]Volume = Length * Width * Height[/tex]
Substitute values for the dimensions
[tex]Volume = 10 * 20 * 10[/tex]
[tex]Volume = 2000\ in^3[/tex]

The current of Cache Creek has speed 2 mph. It takes a small boat a total of 4 hours to travel 12 miles upstream and 12 miles back. Find the speed of the boat in still water. If your answer is not an integer, round it off to two decimal places.
Answer:
6.61 mph
Step-by-step explanation:
Speed of current; c = 2 mph
Total time to travel upstream and back; t = t1 + t2 = 4 hours
Let x represent speed of the boat in still water
Then the actual speed of the boat when going upstream is x - 2, and the actual speed when going downstream downstream is x + 2.
We know that; distance = speed x time, Thus;
For the upstream trip;
12 = (x - 2)t1
t1 = 12/(x - 2)
For the downstream trip;
12 = (x + 2)t2
t2 = 12/(x +2)
Adding both equations, we have;
t1 + t2 = (12/(x - 2)) + (12/(x +2))
4 = (12/(x - 2)) + (12/(x +2))
Multiply through by (x - 2)(x + 2)
4(x - 2)(x + 2) = 12(x + 2) + 12(x - 2)
4x²- 16 = 12x + 24 + 12x - 24
4x² - 16 = 24x
4x² - 24x - 16 = 0
Using quadratic formula, we have;
x ≈ 6.61 mph

A civic group is selling bumper stickers as a fundraiser. During the first week, they sold 500 bumper stickers. During the second week, they sold 50% more bumper stickers than the first week. During the third week, they sold 50% fewer bumper stickers than the second week.
Explain how you can use proportions to find the percent decrease from the first weeks' sales to the third weeks' sales. Your explanation must include the math you did to determine this. If you do not include the math and it make sense you will not get credit for this question.
Answer:
The third week they sold $375 in bumper stickers
Step-by-step explanation:
Proportions and Percentages
During the first week, the civic group sold 500 bumper stickers as a fundraiser.
During the second week. they sold 50% more bumper stickers than the first week. First, we calculate the increment of 50% of 500:
50% 500 = 50 * 500 / 100 = 250
Thus the second week they sold:
500 + 250 = 750 bumper stickers
Now we know the third week they sold 50% fewer than the second week.
Again, we calculate the 50%, but this time on the basis of 750, and not 500 bumper stickers:
50% 750 = 50 * 750 / 100 = 375
Thus the third week they sold:
$750 - $375 = $375
The third week they sold $375 in bumper stickers

In 2004, an art collector paid $ for a particular painting. The same painting sold for $ in 1950. Complete parts (a) through (d). a) Find the exponential growth rate k, to three decimal places, and determine the exponential growth function V, for which V(t) is the painting's value, in dollars, t years after 1950.
Answer:
The value of k is 0.149.
Step-by-step explanation:
The complete question is:
In 2004, an art collector paid $84,275,000 for a particular painting. The same painting sold for $27,000 in 1950. Complete part (a) through (d)? (a) Find exponential growth rate k, to three decimal places, and determine the exponential growth function V, for which V(t) is the painting’s value, in dollars, t years after 1950.
Solution:
The exponential growth function can be expressed as follows:
[tex]y=a\cdot e^{kt}[/tex]
y = Final value after t years
a = initial value
It is provided that:
y = $84,275,000
a = $27,000
The value of t from 1950 to 2004 is, t = 54
Compute the value of k as follows:
[tex]y=a\cdot e^{kt}[/tex]
[tex]84,275,000=27,000\times e^{54k}\\\\e^{54k}=\frac{84275000}{27000}\\\\54k=\ln (\frac{84275}{27})\\\\k=\frac{1}{54}\times \ln (\frac{84275}{27})\\\\k=0.149[/tex]
Thus, the value of k is 0.149.

Solve seven times three and one fifth.
A) twenty two and one fifths
B) twenty two and two fifths
C) twenty two and three fifths
D) twenty two and four fifths
Answer:
B
Step-by-step explanation:
3 1/5 x 7/1
(3 x 5) + 1 = 16/5
16/5 x 7/1 = 112/5.
112 ÷ 5 = 22 2/5
so its B.
Answer:
22 2/5, twenty two and two fifths, B.
Step-by-step explanation:
7 * 3 1/5
To make it simpler, convert 3 1/5 into a mixed number.
3 1/5 = 15/5 + 1/5 = 16/5
Now, it's 7 * 16/5
Next, to prevent confusion, convert 7 to a mixed fraction as well.
7 = 7/1 (also known as a rational number.)
now it's 7/1 * 16/5
Simply multiply 7 * 16 and 1 * 5, which results in
112/5
The answer is a mixed number, and you want to simplify it as much as possible,
112/5 is 5 going into 112 with it's highest factor.
5*22 is 110, which is the highest factor that can go into 112.
now 22 can be the whole number, and the remaining numbers in the part over whole fraction stays put. Basically, you subtract the numerator of the mixed number with the highest factor that the denominator can fit into the numerator. (112-110 = 2)
So, the answer is 22 2/5, B. (cannot be further simplified.)

In tryouts for the olympics a speed skater had times of 44,64,43,45,42,79 and 4,228 seconds find the average time add numbers
Answer:
[tex]Average = 43.29[/tex]
Step-by-step explanation:
Given
Time: 44.64,43.45,42.79 and 42.28
Required
Determine the average time
Average or mean is calculated as thus;
[tex]Mean = \frac{\sum x}{n}[/tex]
Where
[tex]\sum x[/tex] = sum of observation
n = number of observation = 4
[tex]Average = \frac{44.64 + 43.45 + 42.79 + 42.28}{4}[/tex]
[tex]Average = \frac{173.16}{4}[/tex]
[tex]Average = 43.29[/tex]
Hence, the average time is 43.29

Before giving the solution let discuss what is the universal set, Union, and intersection:
A universal set (typically represented by U) is a collection that has items from all the sets, with no elements being repeated.It specifies in general as a set of all items to be considered.It describes all the elements or objects, including the elements, of other collections.The union of two sets is a collection with all A or B components (possibly both).The intersection denotes the resulting set between such two sets, which contains all the common items.Following are the solution to the question:
Given:

Answer:
4p^3 (4p + 1)
Step-by-step explanation:
All we can do with this equation is factor it.
16p^4 + 4p^3
When we look at the coefficients, there is a common factor of 4 with 16 and 4. The p's are also common factors, and we can take out a common factor of x^3. We can combine these common factors and take them out of the equation at the same time.
