Yo can someone do this for me ty i’m too lazy to do this myself

Debora [2.8K]

Answer:

1. 8 + 4 = 12 x 6 = 72

2. 9 + 6 = 15 x 4 = 60

3. 11 + 8 = 19 x 6 = 114

4. 4 + 6 = 10 x 5 = 50

5. 7 + 3 = 10 x 8 = 80

6. 8 + 12 = 20 x 9 = 180

7. 5 + 10 = 15 x 8 = 120

8. 19 + 13 = 32 x 10 = 320

9. 3 + 6 = 9 x 2 = 18

Evaluate the expression 3.14(a2 + ab) when a = 4 and b = 2. (Input decimals only, such as 12.71, as the answer

ivolga24 [154]

3.14((4^2)+(4)(2))
3.14(16+8)
3.14(24)
=75.36

You just want to plug in the values of a and b into the equation and solve using order of operations. Hope this helps!

10. Which travels faster, a car that goes 200 miles in 2 hours, or a

umka21 [38]

<h2>Answer:</h2>

<em>Question 10. </em><u><em>The truck travels faster</em></u><em>.</em>

<em>Question 11. </em><u><em>The slug travels faster</em></u><em>.</em>

<h2>Step-by-step explanation:</h2>

<h2><u>Question 10.</u></h2>

<u />

<h3>1. Find the velocity of each vehicle.</h3>

$Speed=\frac{distance}{time}$

$Speed_{Car} =\frac{200(miles)}{2(hours)}=100mi/h. \\\\ Speed_{Truck} =\frac{300(miles)}{2.5(hours)} =120mi/h.\\ \\$

<h3>2. Compare the velocities.</h3>

$Speed_{Car} =100mi/h < Speed_{Truck} =120mi/h.$

<em>Hence, the trucks travels faster than the car.</em>

<h2><u>Question 11.</u></h2>

<em>Apply the same method as in question 10.</em>

<h3>1. Find the velocity of each body.</h3>

<em /> $Speed_{snail}=\frac{20(cm)}{(3 min)} =6.67cm/min.\\ \\Speed_{slug}=\frac{15(cm)}{(2 min)} =7.5cm/min.$

<h3>2. Compare the velocities.</h3>

$Speed_{snail}=\frac{20(cm)}{(3 min)} =6.67cm/min < Speed_{slug}=\frac{15(cm)}{(2 min)} =7.5cm/min.$

Hence, the slug travels faster.
