The amount of rice harvested this year from 690 acres of farmland was 5211570 bushels

<h3>What is an equation?</h3>

An equation is an expression used to show the relationship between two or more numbers and variables.

This year, a large farm harvested rice from 690 acres of farmland. The crop yield was 7,553 bushels per acre.

Hence:

Amount of rice harvested = 7,553 bushels per acre * 690 acres = 5211570 bushels

The amount of rice harvested this year from 690 acres of farmland was 5211570 bushels

Candice spent 5 1/4 hours doing her homework. Her brother, Ronald, spent 1/2 that number of hours doing his homework. How many h

Elden [556K]

Let

x-----> the number of hours that Candice spent doing her homework

y-----> the number of hours that Ronald spent doing his homework

we know that

$x=5\frac{1}{4}\ hours$

convert mixed number to an improper fraction

$5\frac{1}{4}\ hours=\frac{5*4+1}{4}= \frac{21}{4}\ hours$

so

$x=\frac{21}{4}\ hours$ -------> equation A

$y=\frac{1}{2}x$ ------> equation B

Substitute equation A in equation B

$y=\frac{1}{2}*\frac{21}{4}=\frac{21}{8}\ hours$

convert an improper fraction to a mixed number

$\frac{21}{8}\ hours=2.625=2+0.625=2+\frac{5}{8}=2\frac{5}{8}\ hours$

therefore

<u>the answer is the option B</u>

$2\frac{5}{8}\ hours$

A. -2x + 3y = -15
-2x + 2x + 3y = 2x - 15
3y = 2x - 15

A is correct.

B. y = ²/₃ - 5
B is also correct.

C. 6y = 4x - 30
6 6
y = ²/₃x - 5
C is also correct.

D. y + 3 = ²/₃(x - 3)
y + 3 = ²/₃(x) - ²/₃(3)
y + 3 = ²/₃x - 2
- 3 - 3
y = ²/₃x - 5
D is also correct.

The answer to the problem is A, B, C, and D.

What is the following quotient?

mamaluj [8]

Answer:

A. $2(3^{\frac{1}{3}})-\sqrt[3]{18}$

Step-by-step explanation:

We are given that

$\frac{6-3(\sqrt[3]{6}}{\sqrt[3]{9}})$

We have to find the quotient.

$\frac{6}{\sqrt[3]{9}}-3(\frac{\sqrt[3]{6}}{\sqrt[3]{9}})$

$\frac{2\times 3}{\sqrt[3]{3^2}}-3(\frac{\sqrt[3]{3\times 2}}{\sqrt[3]{3^2}})$

$2\times\frac{3}{3^{\frac{2}{3}}}-3(\frac{2^{\frac{1}{3}}\times 3^{\frac{1}{3}}}{3^{\frac{2}{3}}})$

Using the property

$(ab)^n=a^n\cdot b^n$

$2\times 3^{1-\frac{2}{3}}-3(2^{\frac{1}{3}}\times 3^{\frac{1}{3}-\frac{2}{3}})$

Using the property

$\frac{a^x}{a^y}=a^{x-y}$

$2(3^{\frac{1}{3}})-3(2^{\frac{1}{3}}\times 3^{-\frac{1}{3}})$

$2(3^{\frac{1}{3}})-2^{\frac{1}{3}}\times 3^{1-\frac{1}{3}}$

$2(3^{\frac{1}{3}})-2^{\frac{1}{3}}\times 3^{\frac{2}{3}}$

$2(3^{\frac{1}{3}})-2^{\frac{1}{3}}\times \sqrt[3]{3^2}$

$2(3^{\frac{1}{3}})-2^{\frac{1}{3}}\times \sqrt[3]{9}$

$2(3^{\frac{1}{3}})-\sqrt[3]{2\times 9}$

$2(3^{\frac{1}{3}})-\sqrt[3]{18}$

Hence, the quotient of $\frac{6-3(\sqrt[3]{6}}{\sqrt[3]{9}})$ is given by

$2(3^{\frac{1}{3}})-\sqrt[3]{18}$

Option A is correct.
