Answer:

[tex] - \frac{5}{6} [/tex]

Step-by-step explanation:

The first thing to do is solve for the root. A trick is to ignore the numerator and only focus on the denominator in the root. So it is a third root so you have to find out what multiplied by itself three times is 343. The correct answer for that is 7. So now we must introduce the numerator back, so it would be:

[tex] \frac{1}{7} [/tex]

I'll show the new expression below.

[tex] \frac{1}{6} - 7( \frac{1}{7} )[/tex]

Second order of business is to multiply the second half of the expression. Easy enough the 7 cancels out the 1/7. New expression below.

[tex] \frac{1}{6} - 1[/tex]

Now just solve for that.

[tex] - \frac{5}{6} [/tex]

Answer:

[tex]=75[/tex][tex]ft^{2}[/tex]

Step-by-step explanation:

Area is found by mulitplying width and height.

[tex]A=7.5(5)\\[/tex]

[tex]A=37.5\\[/tex]in

The ratio is 0.5in : 1ft, so if you multiply that ratio to the answer, you should get the answer in feet.

[tex]37.5[/tex]in x [tex]\frac{1ft}{0.5in}[/tex] [tex]=75[/tex][tex]ft^{2}[/tex]

Answer:

0.2821 gal

Step-by-step explanation:

Since this is a direct and proportional relationship, we know that the ratio for 2.539 gal of water to 9 hours is the same as the ratio from the water in the pool after 1 hour to 1 hour. Therefore, we can simplify 2.539:9 into 0.2821111... I’m not sure what value you must round to, so I’ll assume it is to the nearest thousandth. Hence, our answer is 0.2821 gal.

I hope this helps! :)

Answer:

I'm thinking it's A...

==================================================

Explanation:

I'm assuming you meant to say 2 & 1/2 instead of 2,1/2

If so, then we cut that last term 2 & 1/2 in half

The whole part 2 cuts in half to 1

The fractional part 1/2 cuts in half to 1/4

2 & 1/2 cuts in half to 1 & 1/4 which leads to choice C

The reason why we cut in half is because the jump from 20 to 10 is "divide by 2", and the same applies from 10 to 5, and from 5 to 2 & 1/2.

Answer:

area=length*width

3/5*3/10=9/50

9/50 meters squared

Answer:

9/50 meters

Step-by-step explanation:

area = length x width
So just do 3/5 x 3/10
Then you'll get your answer 9/50

Answer:

The correct expression to represent the three consecutive integers whose sum is 21 will be:

Step-by-step explanation:

Let 'a' be the first number

so

a + (a+1) + (a+2) are the three consecutive integers.

Given that the sum of three consecutive integers is 21.

so

a + (a+1) + (a+2) = 21

3a + 3 = 21

subtracting 3 from both sides

3a + 3 - 3 = 21 - 3

3a = 18

a = 6

Therefore, the correct expression to represent the three consecutive integers whose sum is 21 will be:

Note: your option answers are a little unclear, but I hope you may have got an idea about this concept.

Bike 1

Step-by-step explanation:

If you look at the graph, you'll see that Bike 1 went 9 feet but Bike 2 is at about 7.5 feet in 6 seconds.

Answer: Perpendicular

Step-by-step explanation: x-y=5 —-> subtract x from both sides to give you y alone. -y= -x+5 —-> next step is to continue to get y alone so you have to divide both sides by -1. y=x-5 now the first one is done

x+y=-10 —-> solve to get y alone so subtract both sides by x making it y=-x-10 Meaning that the two lines are perpendicular to each other.

Answer:

Because 4 is a perfect square

Step-by-step explanation:

When simplifying a radical, you have to look for perfect squares. 4 is a perfect square but x is not. Variables are only perfect squares if they have even numbered exponents so the x has to stay in the radical.

Answer:

  25.5 cm

Step-by-step explanation:

If the walk is x meters wide, it adds 2x to the overall length and width. Then the area of the walkway is ...

  (2x +5)(2x +6.25) -(5)(6.25) = 6

  4x^2 +22.5x = 6 . . . . simplify left side

  4x^2 +22.5x -6 = 0 . . . subtract 6 to put into standard form

Using the quadratic formula, the walkway width can be found to be ...

  x = (-22.5 +√(22.5² -4(4)(-6)))/(2(4)) = (-22.5 +√602.25)/8

  x ≈ 0.25510

The border width should be about 25.5 cm.

The solution to the inequality 4(c-3)>10 is c > 5.5

Given data:

The inequality is represented as 4(c-3)>10

To solve the inequality 4(c - 3) > 10, we'll follow these steps:

Step 1: Distribute the 4 on the left side of the inequality:

4c - 12 > 10

Step 2: Add 12 to both sides of the inequality to isolate the variable:

4c - 12 + 12 > 10 + 12

4c > 22

Step 3: Divide both sides of the inequality by 4 to solve for c:

(4c)/4 > 22/4

c > 5.5

Hence, the solution is c > 5.5.
