A beaver burrows 10 holes every 5 minutes. How many holes will it burrow if time is increased to 25 minutes

1 answer:

5 0

You can do 25 divide by 5 and you get 5. Then you multiply 5 times 10 and your answer will be of 50. The mole digs 50 holes in 25 minutes.

Find an equation of the line passing through the pair of points. Write the equation in slope-intercept form. (2,8), and (8,2)

leonid [27]

Answer:

$y=-x+10$

Step-by-step explanation:

Hi there!

Slope intercept form: $y=mx+b$ where m is the slope of the line and b is the y-intercept (the value of y when the line crosses the y-axis)

1) Find the slope (m)

$m=\frac{y_2-y_1}{x_2-x_1}$ where the two given points are $(x_1,y_1)$ and $(x_2,y_2)$

Plug in the given points (2,8),and (8,2)

$m=\frac{2-8}{8-2}\\m=\frac{-6}{6}\\m=-1$

Therefore, the slope of the line is -1. Plug this into $y=mx+b$ :

$y=-x+b$

2) Find the y-intercept (b)

$y=-x+b$

Plug in a given point and solve for b

$8=-2+b$

Add 2 to both sides

$8+2=-2+b+2\\10=b$

Therefore, the y-intercept is 10. Plug this back into $y=-x+b$ :

$y=-x+10$

I hope this helps!

Help!!!! Need it now!!! For any number N is greater than 1, is

Basile [38]

Answer:

N is greater than 1.

Step-by-step explanation:

> shows that a number is greater than the other

< shows that a number is less than the other

= shows that a number is equal to the other

~(=) shows that something is congruent to the other

3/4 + 2/3 = 17/12 x n > 1

Patios can be made by mixing cubic meters of cement, gravel, and stones in the ratio 9:4:6. How much gravel is needed to make 20

LenKa [72]

Answer:

44 cubic meters

Step-by-step explanation

9 + 4 + 6 = 19

9/19 of the patio will be cement

4/19 of the patio will be gravel

6/19 of the patio will be stones

Work out the amount of gravel - 4/19 * 209 = 44 cubic meters

What is the answer??

denis-greek [22]

Answer:

10a²+5ab+2b²

Step-by-step explanation:

Start by combining like terms aka the ones that match:

Step 1: (4a²-5ab-6b²) + (10ab+6a²+8b²)

Step 2: (10a²-5ab-6b²) + (10ab+8b²)

Step 3: (10a²+5ab-6b²+8b²)

Final answer: 10a²+5ab+2b²

In step 1, I added the 4 and 6. In step 2, I added -5 and 10. In step 3, I added -6 and 8. For each I attached the proper ending (a², ab, and b²).

I hope this clears some confusion!

Melissa will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $65 and costs an

OleMash [197]

Answer:

Melissa needs to drive 325 miles for the two plans to cost the same

Step-by-step explanation:

Plan A

Initial Fee = 65

Additional cost per mile = 0.50 per mile

Plan B

Initial Fee = 0

Additional cost per mile = 0.70 per mile

Required

Mile both plans will cost the same

Let

$y \to cost$

$x \to miles$

So, we have:

$y = Initial\ Fee + Additional * x$

For plan A

$y = 65+ 0.50* x$

$y = 65+ 0.50x$

For plan B

$y = 0 + 0.70*x$

$y = 0.70x$

So, we have:

$y = 65+ 0.50x$ --- plan A

$y = 0.70x$ --- plan B

Both plans will cost the same when

$y = y$

$0.70x = 65 +0.50x$

$0.70x -0.50x= 65$

$0.20x= 65$

Divide by 0.20

$x= 325$
