Jason and Doug competed in the long jump at a track meet. Jason's long jump was 98 inches. Doug's long jump was 3 yards. How muc
vlada-n [284]
One foot is 12 inches, multiply that by 3 and you have 1 yard.  
To get one yard to 3 yards ad 36+36+36 or 36 X 3 

3 yards is 108.

Drugs jump was 3 yards. 

3 yards = 108
3 yards = Doug's jump
Doug's jump = 108

108- 98 = 10

Doug's jump was 10 inches longer

What are the integer solutions to the inequality below?<br><br> 4x+1&lt;5x≤3(x+2)
Anarel [89]

Given:

The inequality is:

4x+1

To find:

The integer solutions to the given inequality.

Solution:

We have,

4x+1

This compound inequality can be written as two separate inequalities 4x+1 and 5x\leq 3(x+2).

Now,

1

1                 ...(i)

And,

5x\leq 3(x+2)

5x\leq 3(x)+3(2)

5x-3x\leq 6

2x\leq 6

Divide both sides by 2.

x\leq \dfrac{6}{2}

x\leq 3               ...(ii)

From (i) and (ii), we get

1

Here, 1 is excluded and 3 is included in the solution set. There two integer values 2 and 3 in 1.

Therefore, the integer solution for the given inequality are 2 and 3.

Are 9x and 9x2 like terms? Explain why or why not?
enot [183]

Answer:

no

Step-by-step explanation:

they are not like terms because the term 9x^2 is to the 2nd power which means that you are supposed to times the number by itself 2 times and 9x is not to the 2nd power so it stays the same.

A zookeeper weighed an African elephant to be 9 × 103 pounds and an African lion to be 4 × 102 pounds. How many times greater is
lesantik [10]

Answer:

2.25 x 10

Step-by-step explanation:

In the above question, we were given :

The weight of the Elephant = 9 × 10³ pounds

The weight of the African Lion = 4 × 10² pounds

We would compare both weights to determine which size is bigger

Weight of Elephant : Weight of Lion

9× 10³ : 4 × 10²

= 9 × 10³/4 × 10²

= 2.25 × 10¹

= 2.25 × 10

The weight of the elephant is 2.25 × 10 times greater than the weight of the lion.

The curves y = √x and y=(2-x) and the Cartesian axes form two distinct regions in the first quadrant. Find the volumes of rotati
makkiz [27]

Answer:

Step-by-step explanation:

If you graph there would be two different regions. The first one would be

y = \sqrt{x} \,\,\,\,, 0\leq x \leq 1 \\

And the second one would be

y = 2-x \,\,\,\,\,,  1 \leq x \leq 2.

If you rotate the first region around the "y" axis you get that

{\displaystyle A_1 = 2\pi \int\limits_{0}^{1} x\sqrt{x} dx = \frac{4\pi}{5} = 2.51 }

And if you rotate the second region around the "y" axis you get that

{\displaystyle A_2 = 2\pi \int\limits_{1}^{2} x(2-x) dx = \frac{4\pi}{3} = 4.188 }

And the sum would be  2.51+4.188 = 6.698

If you revolve just the outer curve you get

If you rotate the first  region around the x axis you get that

{\displaystyle A_1 =\pi \int\limits_{0}^{1} ( \sqrt{x})^2 dx = \frac{\pi}{2} = 1.5708 }

And if you rotate the second region around the x axis you get that

{\displaystyle A_2 = \pi \int\limits_{1}^{2} (2-x)^2 dx = \frac{\pi}{3} = 1.0472 }

And the sum would be 1.5708+1.0472 = 2.618
