If 37 grams of pure drug are contained in 150 milliliters, how many grams are contained in 75 milliliter?
Answer:
17.5
Step-by-step explanation:
The ratio of "pure drug" to liquid is 35:150
Therefore to evaluate for 75 mls we get the ratio 75/2150 or simply 1/2
multiply 35 by the ratio 1/2
35/2=17.5

A bank loaned out $25,000, part of it at the rate of 12% annual interest, and the rest at 4% annual interest. The total interest earned for both loans was $1,480.00. How much was loaned at each rate?
Answer:
1875
Step-by-step explanation:
The bank loaned part of the $25,500 at a 6% interest rate. We will call this loan amount x. Then the rest of the 25,500 was loaned at a 9% interest rate. We will define this amount as 25,500 - x. We also know that the total interest earned was $1,875. With this information, we form the equation:
.06(x) + .09(25500 - x) = 1,875
.06x + (2,295 - .09x) = 1,875
Simplify the above equation to:
-.03x + 2,295 = 1,875
-.03x = -420
x = 14,000
Since x is the amount loaned at the 6% interest rate, we know that $11,500 was loaned at a 9% interest rate. (25,500 - 14,000 =11,500)
To figure out the amount loaned at 6%, subtract 11,500 from 25,500 ... this gives us 14,000. This means $14,000 was loaned at 6%.
To check:
14,000 x .06 = 840
11,500 x .09 = 1035
840 + 1035 = 1875

A real estate agent has 10 properties that she shows. She feels that there’s a 50% chance of selling any one property during a week. The chance of selling any one property is independent of selling another property. Compute probability of selling no more than six properties in one week
Answer:
Step-by-step explanation:
According to the condition, for any single property the probability not selling it during a week is 100% - 40% = 1 - 0.4 = 0.6.
The probability not selling any one of 13 properties during a week is 0.6%5E13.
The probability to sell at least 1 property in one week is the COMPLEMENT to it

Blake bought a total of 24
doughnuts. Each doughnut cost
$0.84, including tax. Of the
doughnuts he bought, 5/8 were
glazed doughnuts. What was the
total cost of the glazed doughnuts?
Answer:
$27.60
Step-by-step explanation:
Step 1: Find 5 over 8 of 24
[tex]\frac{5}{8}[/tex] doughnuts were glazed. So the total is 24. Now we just have to find 5 over 8 of the total.
[tex]\frac{5}{8} \times 24[/tex]
Or
[tex]\frac{5}{8} \times \frac{24}{1}[/tex]
Cross divide 8 and 24
[tex]24\div 8 = 3\\\\\frac{5}{1} \times \frac{3}{1}[/tex]
So we are left with
[tex]5\times 3[/tex]
Remember, "1" doesn't change anything.
Simplify
[tex]5\times 3 = 15[/tex]
Therefore, the cost of the glazed doughnuts WITHOUT TAX is $15.
Step 2: Add the tax to the cost of the glazed doughnuts.
[tex]\$0.84[/tex]
To find the tax or sales tax, just multiply the sales tax (in decimal form, but it already is) to the total.
[tex]15\times \:0.84=12.60[/tex]
Now, add the result to the total.
[tex]12.60+15.00 = 27.60[/tex] (you don't have to add the zeros, but it still won't change anything)
The total cost of the glazed doughnuts is $27.60A dumpster in the shape of a rectangular prism has a volume of 528 cubic feet. The length of the dumpster is 5 feet less than twice the width w, and the height is 2 foot less than the width. Find the equation, in terms of w, that could be used to find the dimensions of the dumpster in feet. Your answer should be in the form of a polynomial equals a constant.
answer: 2w^3 - 9w^2 + 10w = 528
The dimensions of the dumpster will be 8 feet by 11 feet by 6 feet.
What is the volume of the rectangular prism?Let the prism with a length of L, a width of W, and a height of H. Then the volume of the prism is given as
V = L x W x H
A dumpster in the shape of a rectangular prism has a volume of 528 cubic feet. The length of the dumpster is 5 feet less than twice the width w, and the height is 2 feet less than the width. Then the equation will be
L = 2W - 5 ...1
H = W - 2 ...2
Then the polynomial is given as,
V = L x W x H
528 = (2W - 5)(W - 2)W
528 = (2W² - 5W)(W - 2)
528 = 2W³ - 4W² - 5W² + 10W
0 = 2W³ - 9W² + 10W - 528
Factorize the equation, then we have
2W³ - 4W² - 5W² + 10W - 528 = 0
(W - 8)(4W + 7)² = 0
W = 8, 1.75i, and -1.75i
Then the length and height will be
L = 2 x 8 - 5
L = 11 feet
H = 8 - 2
H = 6 feet
The dimensions of the dumpster will be 8 feet by 11 feet by 6 feet.

Answer:
y = 10x - 6
Step-by-step explanation:
If we know the function is linear then we can use any two coordinate pairs to find the slope of the line.
Note that the first pair is (0, -6) and the last pair is (4, 34). The 'run' is from x = 0 to x = 4, a 'run' of 4. The 'rise' is from -6 to34, a 'rise' of 40. Thus, the slope of this line is m = rise / run = 40/4 = 10.

Coco needs 150mg of a medication that comes in tablets labelled 100mg each. How many tablets will you give her?
Please show work!
Answer:
1.5
Step-by-step explanation:
If 1 tablet is 100mg, and you need 150mg, we set up this equation:
Let x be the number of tablets Coco needs.
x = 150/100
x = 1.5
Therefore, you need 1.5 tablets for the medication.

If a hamburger shop sold a combined total of 423 hamburgers and cheeseburgers but the number of cheeseburgers sold was two
times the number of hamburgers sold. How many hamburgers were sold
Answer:
141
Step-by-step explanation:
First, we choose two variables to represent the two unknown numbers, the number of hamburgers and the number of cheeseburgers.
Let x = number of hamburgers.
Let y = number of cheeseburgers.
Now we use the given information to write two equations using the variables we defined above.
"If a hamburger shop sold a combined total of 423 hamburgers and cheeseburgers"
x + y = 423
"the number of cheeseburgers sold was two
times the number of hamburgers sold"
y = 2x
We have a system of two equations.
x + y = 423
y = 2x
Since the second equation is already solved for y, we can easily use the substitution method. We substitute what y equals to (2x) for y in the first equation.
x + y = 423
x + 2x = 423
3x = 423
x = 141
Since we let x = number of hamburgers, we have the answer.
Answer: 141

Scale factor of similar figures is usually the ratio of one to the other.
In the diagram given, the scale factor is the length of any side of the smaller figure divided by the length of the corresponding side length of the bigger figure.
Length of smaller figure = 3
Corresponding length of larger figure = 6
Scale factor = smaller figure/larger figure = 3/6

lets talk about the basics of pythagoras (maths)?
Answer:
Is there a question?
Step-by-step explanation:
The Pythagorean theorem states that for any right triangle with legs of length “a” and “b” and a hypotenuse of length “c,” the lengths of the sides always satisfy the relationship, “a^2 + b^2 = c^2.” In other words, the sum of the squares of the lengths of the two legs of a triangle is equal to the square of its hypotenuse. The formula is alternatively written with the hypotenuse length isolated (i.e., c = Sqrt(a^2 + b^2).
This is the definition.
