The volume of dry goods, like apples or peaches, can be measured usings bushels, pecks, and quarts. A bushel contains 4 pecks, and a peck contains 8 quarts.
What is the relationship between number of bushels, `b`, and the number of quarts, `q`? If you get stuck, try creating a table.
Answers
Answer: For every 1 bushel, there will be 2 quarts
Step-by-step explanation:
If 4:8, then you would have to divide. To find how much bushels there are in a quart, you would need to divide each number by 4. 4/4 = 1. 8/4 = 2. So, the relationship between b:q would be 1:2

Felicia has $350 to deposit into two different savings accounts. Felicia will deposit $200 into Account I, which earns 4.5% annual simple interest. She will deposit $150 into Account II, which earns 334% interest compounded annually. Felicia will not make any additional deposits or withdrawals. Which amount is closes to the total balance of these two accounts at the end of 6 years?
Answers
Total price after 6 years in Account I is :
[tex]P _1=P_o+\dfrac{P_ort}{100}\\\\P_1=200+\dfrac{200\times 4.5 \times 6}{100}\\\\P_1=\$254[/tex]
Total price after 6 years in Account II is :
[tex]P_2=P_o(1+\dfrac{r}{n})^{nt}\\\\P_2=150(1+\dfrac{3.34}{1})^{1\times 6}\\\\P_2=\$1002373.64[/tex]
Total balance, [tex]T=P_1+P_2=1002373.64+254=\$1002627.64[/tex]
Hence, this is the required solution.
Which inequality is equivalent to the given inequality? -4(x+7)< 3(x-2)
Answers
Answer:
x > -22/7
Step-by-step explanation:
To find out which inequality is is equivalent, you solve for x.
-4(x+7) < 3(x-2): distribute variables
-4x-28 < 3x-6: Add 6 to both sided
-4x-22 < 3x: add 4x to both sides
-22 < 7x: divide by 7
-22/7 < x: you can switch sides if prefered but you have to switch sign too
x > -22/7

The product in scientific notation is 1.32 × 10²⁵.
What is scientific notation?Scientific notation is a method for expressing numbers that are too large or too small to be easily written in decimal form (usually resulting in a long string of digits). It is known as standard form, scientific form, or standard index form. Scientists, mathematicians, and engineers all use this base ten notation because it can simplify some arithmetic operations. It is typically referred to as "SCI" display mode on scientific calculators.
Non-zero numbers are written in the form (m x n¹⁰) in scientific notation.
Given (11 x 10¹¹)(12 x 10¹²)
11 x 10¹¹ x 12 x 10¹²
132 x 10¹¹⁺¹² (base same add powers)
132 x 10²³ (132 can be written as 1.32 x 100)
1.32 x 100 x 10²³
1.32 x 10²³⁺²
1.32 x 10²⁵
Therefore the scientific notation is 1.32 x 10²⁵.

9(5 - x) = 81
x = [?]
Answers
Answer:
[tex]\boxed {x = -4}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]9(5 - x) = 81[/tex]
-Use Distributive Property:
[tex]9(5 - x) = 81[/tex]
[tex]45 - 9x = 81[/tex]
-Subtract [tex]45[/tex] to both sides:
[tex]45 - 45 - 9x = 81 - 45[/tex]
[tex]-9x = 36[/tex]
-Divide both sides by:
[tex]\frac{-9x}{-9} = \frac{36}{-9}[/tex]
[tex]\boxed {x = -4}[/tex]
So, the value of [tex]x[/tex] is [tex]-4[/tex].
Damon is 7 years older than his brother Mark. The sum of Damon and marks age is 29
Answers
Answer:
Damon is 18, Damon's brother is 11 years old.
Step-by-step explanation:
So, the total age of them both is 29. Damon is 7 years older, so we use 29-7=22. Now, 22 is Damon's brother's age times 2, so we use 22/2=11. 11 is Damon's age is 11+7=18, and His brothers age is 11.
Answer:
daman's age = (7+x)
let his brother's age be 'x'
according to the question,
(7+x) + x =29
7+x+x = 29
2x = 29 - 7
2x = 22
x = 22÷2
x = 11 = age of daman's brother
age of daman = 7+11 = 18
