Gabe Amodeo, a nuclear physicist, needs 90 liters of a 50% acid solution. He currently has a 30% solution and a 60% solution. How many liters of each does he need to make the needed 90 liters of 50% acid solution?
Answer:
You need two equations: one for solution amounts and one for alcohol amounts.
Step-by-step explanation:
90 = X + Y
45 = (0.6)/X + (0.3)Y
Here X = amount of 60 % solution and Y = amount of 30 percent solution. Note that percentages have been converted to decimal amounts in the second equation.
From here you have to solve two equations with two unknowns. Easiest to solve first equation for X = 90 - Y, then substitute into second equation. this get you one equation in one unknown. Solving you you will get
X = 30 liters and Y = 60 liters.

А 1 cm
B. 5 cm
C. 11 cm
D. 25 cm
5 is the answer
here we have hypoteaus and base
so by using pythagoreaus theorem
p^2 = h^2 - b^2
p^2 = 13^2 - 12^2
p^2 = 169 - 144
p^2 = 25
p = root under 25
p = 5
Answer:
5 cm
Step-by-step explanation:
A^2+B^2=C^2
12^2+B^2=13^2
144+B^2=169 (You have to subtract 144 from both sides to get B^2 by its self)
-144 = -144
B^2= 25 (To get rid of the square you have to find the square root)
Square root of 25 = 5cm

Mr. Smith has a maximum of $50 to spend at a museum. A ticket to the museum costs $7. He
can spend p dollars to buy other things at the museum. Which inequality can be used to find
the possible values for p?
Answer:
Step-by-step explanation:
After buying the ticket, the amount with him = 50 - 7 = 43
p ≤ 50 - 7
p ≤ 43
Answer:
p≤ 43
Step-by-step explanation:
50-7=43
so now Mr.smith will have $43 to spend
p is less than or equal to 43

Armando has 3 blue shirts, 3 green shirts,
and 2 red shirts. He has 3 pairs of jeans
and 4 pairs of cargo pants. He is equally
likely to wear any of the shirts with any
pair of pants. What is the probability that
Armando will wear a green shirt with cargo pants?
Answer:
0.2143 = 21.43% probability that Armando will wear a green shirt with cargo pants.
Step-by-step explanation:
Probability:
A probability is the number of desired outcomes divided by the number of total outcomes.
Probability of independent events:
The probability of two independent events is the multiplication of their separate probabilities.
Green shirt:
3 green shirts, out of 3 + 3 + 2 = 8 shirts.
So 3/8 probability of green shirts.
Cargo pants:
4 cargo pants, our of 4 + 3 = 7.
So 4/7 probability of cargo shirts.
Green shirt and cargo pants:
[tex]p = \frac{3}{8} \times {4}{7} = \frac{12}{56} = \frac{3}{14} = 0.2143[/tex]
0.2143 = 21.43% probability that Armando will wear a green shirt with cargo pants.

Answer:
1) $68.40
2)456 tickets
Step-by-step explanation:
1)
They need to raise $8,250.
They have already raised $3,120.
The amount they have still to raise is $8,250-$3,120=$5,130.
There are 75 band members, so the amount yet to raise per member is $5,130/75=$68.40.
2)
The businesses give $0.50 for every $1 in ticket sales, ie. they pay an extra 50% of the total.
Let number of tickets sold=x
Let money made from ticket sales = 7.5x
The total amount of money made is therefore 1.5(7.5x)=11.25x
The minimum amount of tickets to hit $5,130:
$5,130=11.25x
x=456

Step-by-step explanation:
An automobile manufacturer sold 30,000 new cars, one to each of 30,000 customers, in a certain year. The manufacturer was interested in investigating the proportion of the new cars that experienced a mechanical problem within the first 5,000 miles driven. a) A list of the names and addresses of all customers who bought the new cars is available. Each customer from a simple random sample of 1,000 customers who bought one of the new cars was asked whether they experienced any mechanical problems within the first 5,000 miles driven. 400 customers from the sample reported a problem. Of the 400 customers who reported a problem, 140 customers, or 32.5%, reported a problem specifically with the power door locks. Explain why 0.35 should not be used to estimate the population proportion of the 30,000 new cars sold that experienced a problem with the power door locks within the first 5,000 miles driven.
Answer:
The reason that 0.35 should not be used to estimate the population proportion of the 30,000 new cars sold that experienced a problem with the power door locks within the first 5,000 miles driven is that 0.35 does not represent the sample proportion.
The correct sample proportion is 0.14 (140/1,000) and not 0.35 (140/400). It is this that can be used to estimate the population proportion and not 0.35.
Step-by-step explanation:
a) Data and Calculations:
New cars sold by the automobile manufacturer = 30,000
Number of customers that the 30,000 new cars were sold to = 30,000
Simple random sample = 1,000 customers
Number of customers from the SRS that reported a problem = 400
This is equal to 40% of the sample (400/1,000 * 100)
Proportion of customers who reported a problem (specifically) with the power door locks = 140/400 = 0.35
Proportion of customers out of the sample that reported specifically a problem with the power door locks = 140/1000 = 0.14.

PETS Each month Travis spends $20 for premium food$10 for treats $18 for grooming, and $3 for toys for his pet. Write an expression that could be used to determine the amount he spends on these items for his pet over a period of 12 months.
Answer:
$492 per year
Step-by-step explanation:
The first step we take towards solving this question is to add all the numbers we were given as money spent(excluding that of the month)
$20 + $10 + $18 + $3 = $41 per month
This means that a total of $41 was spent per month.
Going further, since we're told it's 12 months, we then multiply it by 12, and thus, we have
$41 * 12 = $492 per year
Therefore, the total money spent is $492 per 12 months, or per year

(HELP)matt weighed 60 pounds when he was 8 he now weighs 80 pounds. Find the percent of increase in weight rounded to the nearest tenth
O 20.0%
O 25.0%
O 30.0%
O 33.3%
Answer:
Percent of increase in weight = 33.33% Approx.
Step-by-step explanation:
Given:
Old weight = 60 pound
New weight = 80 pound
Find:
Percent of increase in weight
Computation:
Percent of increase in weight = [(New weight - old weight)/Old weight]100
Percent of increase in weight = [(80 - 60)/60]100
Percent of increase in weight = [(20)/60]100
Percent of increase in weight = 33.33% Approx.

Help 30 point question!
You're given 3 points (x, y) on the circle with equation
x ² + y ² + Dx + Ey + F = 0
and you have to use these known points on set up 3 equations involving D, E, and F.
For the point (3, -1), this means when x = 3, y = -1, so
3² + (-1)² + 3D - E + F = 0
→ 3D + (-1)E + 1F = -10
The next point (-2, 4) gives
(-2)² + 4² - 2D + 4E + F = 0
→ (-2)D + 4E + 1F = -20
And from the last point (6, 8),
6² + 8² + 6D + 8E + F = 0
→ 6D + 8E + 1F = -100
Find the value of the power.
