The total cost of 3 bags of chips and 4 jars of salsa at a
store is $11.25. The cost of each bag of chips is $2.75.
Write an equation that can be used to determine the cost
,
X, of 1 jar of salsa.
Answers
Answer: 2.75(3) + 4x = 11.25
Step-by-step explanation:
It says each bag costs $2.75 and there are 3 bags so multiply those 2 and then subtract them from the total cost (11). What you get after you subtract is the total costs of the salsa so divide that by 4 to get the cost of each, in this case it doesn't ask so we leave it as 4x.
two trucks leave a factory at the same time. one travels east 60 miles per hour, and the other travels west at the 39 miles per hour. in how many hours will they be 150 miles apart?
Answers
9514 1404 393
Answer:
1 17/33 hours, about 1.52 hours
Step-by-step explanation:
The distance between the trucks is increasing at the rate of 60+39 = 99 miles each hour. Then the time to get to a separation distance of 150 miles is ...
(150 mi)/(99 mi/h) = (150/99) h = 1 17/33 h
The trucks will be 150 miles apart after ...
1 17/33 hours, about 1 hour 30 min 55 seconds.

When you flip a based coin the probability of getting a tail is 0.39. What's the probability of getting head
Answers
Answer:
0.61 or 61 %
Step-by-step explanation:
Answer:
0.61
Step-by-step explanation:
0.39 is also 39%, the highest probability is always 100% unless it says otherwise, so our equation is:
1 - 0.39 = 0.61
So the probability of getting a head is 0.61 or 61%

Solve for x -2(4x-3)=30
X=-2
X=-3
X=-4
X=-6
Answers
Answer:
Step-by-step explanation:
x-2(4x-3)=30
x-8x+6=30
-7x=30-6
-7x=24
x=-24/7 maybe it is a mistake in the statement of the problem
Then you have to combine like terms -7x+6=30
Move the constant to the right which will be -7x=30-6
Then you subtract the numbers -7x=24
Divide both sides by -7 so it equals x=-24/7
Which equals x=-4
Stefan sells Jin a bicycle for $137 and a helmet for $17. The total cost for Jin is 140% of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally? How much money did he make bying the bicycle and helmet to Jin? Stefan originally spent $
Answers
Answer:
Stefan originally spent $110.
Stefan made a profit of $44.
Step-by-step explanation:
Given that:
Stefan sold the bike and helmet for $137 and $17
Total amount = 137+17 = $154
This is 140% of the price Stefan originally paid.
Let,
x be the original price paid by Stefan
140% of x = $154
[tex]\frac{140}{100}x=154\\1.4x = 154\\\frac{1.4x}{1.4}=\frac{154}{1.4}\\x=110[/tex]
Therefore,
Stefan originally paid $110 for the bicycle and helmet.
Profit made by Stefan = 154-110 = $44
Hence,
Stefan originally spent $110.
Stefan made a profit of $44.

What proportion of the sampled wafers had at least one particle
Answers
) What proportion of the sampled wafers had at least one particle? At least five particles? (Round your answers to two decimal places.)
Answer:
0.99
0.71
Step-by-step explanation:
The total number of frequency is 100 when added together
A.
The proportion with at least one particle.
Here we are to get :
Total frequency - (frequency of cases whose particles are 0.)
= 100-1
= 99
99/100
= 0.99
B.
At least 5 particles:
Total number of frequency - (cases that have frequencies with 4 or less particles)
= 100 - (12+11+3+2+1)
= 100 - 29
= 71
71/100
= 0.71
