Answer:
2:40 p.m.
Step-by-step explanation:
Annike's 11-mile head start is being made up by Celia at the rate of 3 miles per hour. It will take Celia 11/3 = 3 2/3 hours to catch Annike. 3 hours and 40 minutes after 11 a.m. is 2:40 p.m..
Celia and Annike will both have completed 51 1/3 miles at 2:40 p.m..
_____
distance = speed×time
Annike: 11 mph × 4 2/3 h = 51 1/3 mi
Celia: 14 mph × 3 2/3 h = 51 1/3 mi
Answer:
Since there are 2 sides, a front & back, and a top & bottom, you must find the surface area of each of those 3 surfaces and multiply by 2.
Step-by-step explanation:
The formula would be:
Top & Bottom - 5 × 4 (multiply by 2 for top AND bottom)
Front & Back - 5 × 7 (multiply by 2 for front AND back)
Sides - 4 × 7 (multiply by 2 for BOTH sides)
___________________________________________________
Once you find the 3 surface areas, add the areas all together for the total. (I did not show the answer because that is for you to do on your own.)
Ex. Top & Bottom + Front & Back + Sides
Answer:
= - 9x2+4x+2/4x-2
Step-by-step explanation:
Remove parentheses
its blank we need to find a number
step 1: = -/4x-2 (9x2+4x+2)
step 2: multiply fractions and there is your answer
9x2+4x+2/4x-2
Answer:
24
Step-by-step explanation:
Step 1: Define
x = 2
y = 4
16x + 2x² - y²
Step 2: Substitute and Evaluate
16(2) + 2(2)² - 4²
32 + 2(4) - 16
16 + 8
24
