Answer:
4 hrs
Step-by-step explanation:
22.8-17.6=5.2
so they are 5.2 miles apart.
Let they meet after t hrs.
distance coverd by Quico in t hrs=2.6t
distance covere by Chespirito in t hrs =3.9t
3.9t-2.6 t=5.2
or 1.3 t=5.2
t=5.2/1.3 =4

Step-by-step explanation:
Answer:
11.25 or 11 1/4
Step-by-step explanation:
seeing as how tiled in this sense essentially means 'cut' we have to look at the following rectangle as 2 separate rectangles instead of one whole
so we'll let the biggest rectangle be rectangle one and the smallest rectangle two-
now we need the dimensions of each one-
rectangle one
l=5 w=2
rectangle two
l=5 w=1/4
now let us set up the equation and solve-
a=lw
rectangle one
a=5*2=10
rectangle two
a=5*1/4=1.25
and the last step is to add together the areas of both rectangles
10+1.25=11.25
and since you need your answer as a mixed number the answer is 11 1/4
(to do this you just put 11.25 over 100 and then simplify)
good luck :)
i hope this helps
brainliest would be highly appreciated

ENTERTAINMENT For Exercises 19 and 20, use the following information.
Fairfield High spent d dollars for refreshments, decorations, and advertising for a dance. In
addition, they hired a band for $550.
19. Write an expression that represents the cost of the band as a
fraction of the total amount spent for the school dance.
20. If d is $1650, what percent of the budget did the band account for?
Answer:
D + 550 = X
The band accounted for 25% of the budget.
Step-by-step explanation:
Since Fairfield High spent D dollars for refreshments, decorations, and advertising for a dance, and in addition, they hired a band for $ 550, to write an expression that represents the cost of the band as a fraction of the total amount spent for the school dance and determine, if D is $ 1650, what percent of the budget did the band account for, the following calculations must be performed:
D + 550 = X
D = 1650
1650 + 550 = X
2200 = X
2200 = 100
550 = X
550 x 100/2200 = X
55,000 / 2,200 = X
25 = X
Therefore, the band accounted for 25% of the budget.

C. Two motorcycles start at the same point. One travels 15 km due north and stops while the other travels 32 km due west
and stops. Which value is closest to the distance between the motorcycles when they are both stopped?
A. 28.3 km
B. 47.0 km
C. 35.3 km
D. 21.9 km
9514 1404 393
Answer:
C. 35.3 km
Step-by-step explanation:
From your knowledge of right triangles, you know that the hypotenuse is longer than the longest leg and shorter than the sum of the legs.
For this geometry, the distance of interest is longer than 32 km and shorter than 15+32 = 47 km. The only answer choice in the correct range is ...
35.3 km

Step-by-step explanation:
A model rocket is launched with an initial upward velocity of 62/ms. The rocket's height h (in meters) after t seconds is given by the following.
h=62t-5t^2
Find all values of t for which the rocket's height is 29 meters.
Round your answer(s) to the nearest hundredth.
9514 1404 393
Answer:
t = 0.49, 11.91
Step-by-step explanation:
A graphing calculator can show you the answers quickly. The times are 0.49 seconds and 11.91 seconds.
__
We can write the equation as ...
h = 29
62t -5t^2 = 29 . . . . . substitute for h
-5(t^2 -12.4t) = 29
-5(t^2 -12.4t +6.2^2) = 29 -5(6.2^2) . . . . complete the square
-5(t -6.2)^2 = -163.2 . . . . . simplify
t -6.2 = ±√(-163.2/-5) = ±√32.64 . . . . divide by -5, take the square root
t = 6.2 ±5.71
t = 0.49, 11.91
The rocket has a height of 29 meters at t=0.49 seconds and t=11.91 seconds.

You buy a new backpack that costs $62.00. The sales tax is 6.5%. What is the total amount you need to pay, including tax?
Answer:
$66.03 in total.
Step-by-step explanation:
$66.03 because 6.5% is 0.065 and $62.00 times 0.065 equals $4.03. $62.00 plus $4.03 is $66.03.
