Answers

Answer 1

Answer:

c= -6

Step-by-step explanation:

2(2c+9)=c

4c+18=c

4c+18-18=c-18

4c=c-18

4c-c=c-c-18

3c=-18

3c/c=-18/3c

c= -6

carpeting is needed to cover a 60 feet length room and 40 feet width ​

Answers

Answer:

[tex]266[/tex] [tex]\frac{2}{3}[/tex] [tex]yards[/tex]

Step-by-step explanation:

1. Approach

First, convert the dimensions of the room from feet to yards. Remember, the conversion rate between feet and yards is, [tex]3feet=1yard[/tex]. Next, find the area of the room by multiplying the length by the width.

2. Convert the unit of measurement

The measurement unit is given in feet, one must convert it into yards. The conversion rate between yards and feet is, [tex]3feet=1yard[/tex].

[tex]60feet=20yards\\\\40feet=13\frac{1}{3}yards[/tex]

3. Find the area of the room

Now multiply the length by the width to find the area of the room.

[tex]20yards*13\frac{1}{3}yrads\\\\= 20 * \frac{40}{3}\\\\=\frac{800}{3}\\\\= 266\frac{2}{3}_{.}yards^{2}[/tex]

Answer:

D  

Step-by-step explanation:

Two lines are parallel if they have the same slope.

the given equation is in the form

y=mx+b

where

m=-5/2

b=-7

m is the slope.  You can see this by noting that if you increase x by 1 you increase y by m.

So, in this case, you are looking for a line with slope of -5/2.

You can solve each of the choice equations for y to see which one has the right slope.

A: y=(2/5)x-6   no good

B: y=-(2/5)x-1   no good

C: y=(5/2)x-4   no good

D: y=-(5/2)x-4  GOOD

In a video game, a guppy that escapes a net turns into three goldfish. Each goldfish can turn into two betta fish. Each betta fish can turn into two angelfish. Complete the diagram and write the number of fish at each stage. Write and evaluate an expression for the number of angelfish that can be formed from one guppy

Answers

Answer: 1 guppy = 3 goldfish

1 goldfish = 2 betta fish.....so 3 goldfish = (3 * 2) = 6 betta fish

1 betta fish = 2 angel fish....so 6 beta fish = (6 * 2) = 12 angel fish

so the number of angelfish that can be formed by 1 guppy is 12 angelfish

A tea shop brewed 8 7/8 pitchers of chamomile tea, of which it sold 2 3/5 pitchers. How many pitchers remained unsold?

Answers

Answer:6 11/40

Step-by-step explanation: You can change your units to decimals or to fractions of equal value.  Decimals are easier for this so 8 7/8= 8.875 and 2 3/5 =2.6.  Then subtract: 8.875-2.6= 6.275   You can now convert back to a fraction by simplifying the .275 into 11 by dividing by 25 and 1000 into 40 by dividing by 25.  6+11/40= 6 11/40 tea left

Answer:

6 11/40

Step-by-step explanation:

First you have to convert the fractions into improper fractions, where 8 7/8 would turn into 71/8 and 2 3/5 would turn into 13/5. Then you have to find a common denominator which would be 40, so you get 355/40 and 104/40. Then to find the remaining amount, you have to subtract 104/40 from the 355/40, so 355/40 - 104/40, which equals 251/40. This turns into 6 11/40, which can't be simplified any further. Hope this helps :)

A rectangular pool is 6 feet by 12 feet. A 4 foot walkway is placed around the entire pool. What is the area of just the walkway?

PLEASEE HELP

Answers

Ok so the answer is 88 feet^2.

Explanation: First we would find the area of the pool. 6 times 12 is 72.
Since 4 feet is added add that to 6 AND 12.
Now multiply 10 and 16. 10 * 16 = 160.
Subtract 72 from 160. 160-72= 88 ft^2

Answer:

[tex]\sqrt[3]{8+3\sqrt{21} } + \sqrt[3]{8-3\sqrt{21} }[/tex] = 1

Step-by-step explanation:

Given[tex]\sqrt[3]{8+3\sqrt{21} } + \sqrt[3]{8-3\sqrt{21} }[/tex]To find The value of the expressionSolution

Let's rewrite the given as:

[tex]\sqrt[3]{3\sqrt{21} + 8} - \sqrt[3]{3\sqrt{21} - 8}[/tex]

Let the value is m and the expressions under 3rd roots are a and b, then we have

a = 3√21 + 8, b = 3√21 - 8m = ∛a - ∛b

Cube the both sides:

m³ = (∛a - ∛b)³m³ = a - b - 3[tex]\sqrt[3]{a^2b}[/tex] + 3[tex]\sqrt[3]{ab^2}[/tex]

Simplify in bits:

a - b = 3√21 + 8 - 3√21 + 8 = 16ab = (3√21 + 8)(3√21 - 8) = 9*21 - 64 = 125∛ab = ∛125 = 5

So the expression becomes:

m³ = 16 - 3[tex]\sqrt[3]{125a} + \sqrt[3]{125b}[/tex]m³ = 16 - 15∛a + 15∛bm³ = 16 - 15(∛a - ∛b)m³ = 16 - 15m

Solve for m:

m³ + 15m - 16 = 0m³ - 1 + 15m - 15 = 0(m - 1)(m² + m + 1) + 15(m - 1) = 0(m - 1)(m² + m + 16) = 0m - 1 = 0, m² + m + 16 = 0m = 1 is the only real root, the quadratic equation has no real roots
