Answer:
2 cups of sugar
Step-by-step explanation:
Set up a proportion where x is the amount of sugar for 7.5 flour cups
[tex]\frac{3}{0.8}[/tex] = [tex]\frac{7.5}{x}[/tex]
Cross multiply and solve for x:
3x = 6
x = 2
So, you will need 2 cups of sugar

The loudest animal on Earth is the blue whale. Blue whales can emit sound with an intensity of 106.8 watts/meter2. The equation
log
by the human ear, Io (approximately 1 x 10-12 watts/meter).
Based on this information, which value is closest to the sound level, in decibels, of the vocalizations of a blue whale?
A.
140 dB
B.
100 dB
C. 240 dB
D. 1,000 dB
Answer:
140 db
Step-by-step explanation:
I have succesfully finished tihs
The value is closest to the sound level of the vocalizations of a blue whale is 140dB.
We have given that,
Intensity(I)= 106.8 watts/meter^2
The intensity of sound hair by the human ear is,
[tex]I_0=1\times10^{-12}[/tex]
What is the meaning of the sound intensity?Sound intensity is defined as the power carried by sound waves per unit area in a direction perpendicular to that area.
We have to find which value is closest to the sound level, in decibels, of the vocalizations of a blue whale
So we have given the formula
[tex]B=10 log(\frac{I}{I_0} )[/tex]
So use the given value we get
[tex]B=10 log(\frac{106.8}{1\times 10^{-12}} )[/tex]
B= 140.28 dB≈140 dB
Therefore the value is closest to the sound level of the vocalizations of a blue whale is 140dB.

4x + 5y = -10
4x + 3y = -22
Solve by using the method of elimination
Answer:
y=6. &. x = -10
Step-by-step explanation:
if 4x + 5y = -10
then 4x = -10 -5y. ---------->(1)
if 4x + 3y = -22
then 4x = -22 -3y. ------------>(2)
from equation (1) & (2) :
then -10 -5y = -22 -3y
then 22 -10 = 5y -3y
12 = 2y
then y=6
substituting in (1) or (2):
then. x= -10

The regular price of a skateboard is p. Which expression represents the price of the skateboard when it is on sale for 25% off? Select all that apply.
Answer: The expression represents the price of the skateboard when it is on sale for 25% off = 0.75p
Step-by-step explanation:
Given: Regular price of a skateboard is p.
Discount = 25% off = 0.25p
Now, the price of the skateboard when it is on sale for 25% off = p - Discount
= p -0.25p
= (1-0.25)p
= 0.75p
Hence, the expression represents the price of the skateboard when it is on sale for 25% off = 0.75p
Answer: The expression represents the price of the skateboard when it is on sale for 25% off = 0.75p

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
From the table,
Amount of energy used.
First-year: 1,000,000
Second-year: 900,000
Third year: 810,000
Fourth-year: 792,000
The difference between the amount of energy between consecutive years.
1,000,000 - 900,000 = 100,000
900,000 - 810,000 = 90,000
810,000 - 792,000 = 18,000
We see that,
There is a different amount of energy decreasing each year.
Thus,
The amount of energy used decreases by a different amount each year.

10. A bag of cat food contains 4
pounds. Each serving is 4 of a cup.
How many servings are in the bag?
Answer:
16
Step-by-step explanation:
each pound has 3.6 cups
1/4 of a pound can be multiplied
3.6 x 1/4 = 0.9
then we subtract 4 - 3.6 = 0.4 say if the question was for one pound
But we have to find 14.4 cups instead as;
3.6 x 4 = 14.4 = 4 pounds
We go back to 0.9 are first smaller serving = 1/4 cup
14.4/0.9 = 16

Answer:
B) 3 1/3
Step-by-step explanation:
To divide the fractions, simply follow these steps.
First, flip the second fraction, so that the numerator is the denominator, and the denominator is the numerator. Change the division sign into a multiplication:
(2/3)/(1/5) = (2/3) * (5/1)
Next, multiply straight across:
(2/3) * (5/1) = (2 * 5)/(3 * 1) = 10/3
Finally, simplify. Change the improper fraction into a mixed:
10/3 = 3/3 + 3/3 + 3/3 + 1/3 = 3 1/3
B) 3 1/3 is your answer.
