A cook used 6 gal of cooking oil last month. She used 15% less this
month. How much cooking oil did she use this month?
Answer:
100%-15%=85%
She used 85% of the total oil for last month
So 6gallons × 85 ÷ 100 = 5.1 gal
In 1998, Hurricane Bonnie approached the United States at a speed of 8 miles per hour. The function y = 8x describes how many miles y Hurricane Bonnie traveled x hours. Use the graph to estimate how far the hurricane traveled in 2.5 hours.
Answer:
20 miles
Step-by-step explanation:
Given the equation of the line of the graph, y = 8x, where,
y = distance the hurricane travelled in miles
x = time of travel in hours
8 = slope/speed in miles/hour
To find how far the hurricane travelled in 2.5 hours, substitute x = 2.5 into y = 8x
This:
y = 8(2.5)
y = 20 miles
Thus, from the graph, we can estimate this also. On the x-axis, between 2 and 3, we have 2.5 hours. The corresponding value of x = 2.5 is y = 20.
Convert 60 quarts to gallons. 60 qt = ? gal Will the converted amount have more or fewer units than the original?
Answer: 15 gallons .
Step-by-step explanation:
Step 1
4 quarts = 1 gallon
therefore 60 quarts = (60 quarts x 1 gallon) / 4 quarts
= 15 gallons .
Step 2-- The converted amount which is 15 has fewer units than the original which is 60.

The school band decided to make pizza kits to sell for their fundraiser.
The materials cost them $
1500, and they sold the pizza kits for $8.50 a
kit. The Function below can be used to find the profit p(x), where x is
the nunuer of kits sold.
P(x) = 8.50x- 1500
If the band made a profit of $2920, how many pizza kits were sold?
a. 167 kits
b. 344 kits
C. 402 kits
d. 520 kits
Answer:
520
Step-by-step explanation:
Given that:
Profit function p(x) is :
P(x) = 8.50x- 1500
If the profit made = $2920 ; the number of pizza kits sold is :
Then p(x) = 2920
Putting p(x) = 2920 in the equation :
2920 = 8.50x - 1500
2920 + 1500 = 8.50x
4420 = 8.50x
Divide both sides by 8.50
4420 / 8.50 = 8.50x / 8.50
520 = x
Hence, number of pizza kits sold is 520

What value of x will make the polygon a parallelogram?
Step-by-step explanation:
In a parallelogram, opposite sides are equal.
Hence 3x = 6 and x = 2.
a. -6 + 2x + 4 + 3x - (-2)
What is the answer?
Answer:
5x
Step-by-step explanation:
-6 + 2x + 4 + 3x - (-2)
rearrange to make it easier to solve
2x + 3x - 6 + 4 - (-2)
add like terms, negative time negative is positive
5x - 2 + 2
5x
5(x-3y)-2x=6 and x=3y
Solve the equations please by substitution
Answer for the first equation:
(7, -1)
Step-by-step explanation:
Original Equation: 5(x - 3y) - 2x = 6 When x = 3y
Substitute in the 3y for x:
5(3y - 3y) - 2(3y) = 6
5(0) - 6y = 6
-6y = 6
y = -1
Plug -1 in for y in the original equation:
5(x -3(-1)) - 2x = 6
5(x + 3) - 2x = 6
5x + 15 - 2x = 6
3x + 15 = 6
3x = -9
x = -3
The mean balance of all checking accounts at a bank on December 31, 2005, was $900. A random sample of 53 checking accounts taken recently from this bank gave a mean balance of $841 with a standard deviation of $190. Using the 1% significance level, can you conclude that the mean balance of such accounts has decreased during this period
Answer:
Step-by-step explanation:
Given that:
The population mean μ = 900
The sample size n = 53
The sample mean = 841
The standard deviation = 190
The level of significance = 0.01
To test the claim that the mean balance of the accounts has decreased during the period.
The null and the alternative hypothesis can be computed as:
[tex]H_o : \mu \ge 900 \\ \\ H_1 : \mu < 900[/tex]
This is a left-tailed test since the alternative is less than 900
The test statistics can be computed as:
[tex]Z = \dfrac{\overline x - \mu}{\dfrac{s}{\sqrt{n}} }[/tex]
[tex]Z = \dfrac{841 -900}{\dfrac{190}{\sqrt{53}} }[/tex]
[tex]Z = \dfrac{-59}{\dfrac{190}{7.28}}[/tex]
Z = -2.26
The p-value = P(Z < -2.26)
From the z-tables
The p-value = 0.01191
The p-value ≅ 0.012
Decision rule: To reject the null hypothesis if the significance level is > p-value.
We failed to reject the null hypothesis.
Conclusion: Thus, there is insufficient evidence to conclude that such accounts mean balance has decreased during this period.

A contractor needs to buy nails to build a house. The nails come in small boxes and large boxes. Each small box has 50 nails and each large box has 350 nails. The contractor bought 5 more large boxes large boxes than small boxes, which altogether had 2550 nails. Determine the number of small boxes purchased and the number of large boxes purchased.
Answer:
Number of small boxes purchased : 2
Number of large boxes purchased : 5
Step-by-step explanation:
Let,
x be the number of small boxes of nails purchased
y be the number of large boxes of nails bought
Then according to given statement;
50x+350y = 2550 Eqn 1
y = x+5 Eqn 2
Putting value of y from Eqn 2 in Eqn 1
50x + 350(x+5) = 2550
50x + 350x + 1750 = 2550
400x = 2550-1750
400x = 800
Dividing both sides by 400
[tex]\frac{400x}{400}=\frac{800}{400}\\x=2[/tex]
Putting x=2 in Eqn 2
y = 2+5
y = 7
Hence,
Number of small boxes purchased : 2
Number of large boxes purchased : 5

Which sentence has modifiers in the right place to make its meaning clear?
A.
Every year, we bought a homemade apple pie at a little store that cost only $5 on the road to the cabin.
B.
Every year, we bought a homemade apple pie that cost only $5 at a little store on the road to the cabin.
C.
Every year, we bought a homemade apple pie at a little store on the road to the cabin that cost only $5.
The correct answer is B. Every year, we bought a homemade apple pie that cost only $5 at a little store on the road to the cabin.
Explanation:
In the sentences presented the section "that cost only $5" is a modifier because this describes the noun "homemade apple pie". Moreover, this modifier should be placed right after the noun it describes to clarify the "$5" refer to the cost of the pie.
This occurs in option B "a homemade apple pie that cost only $5" because this places the modifier after the noun, and this makes the sentence to be clear. On the other hand, in other options the meaning is confusing. For example in A "a homemade apple pie at a little store that cost only $5," it is not clear if the cost refers to the apple or the store.
