A car is traveling on a small highway and is either going 55 miles per hour or 35 miles per hour, depending on the speed limits, until it reaches its destination 200 miles away. Letting x represent the amount of time in hours that the car is going 55 miles per hour, and y being the time in hours that the car is going 35 miles per hour, an equation describing the relationship is:
55x + 35y = 200
If the car spends 2.5 hours going 35 miles per hour on the trip, how long does it spend going 55 miles per hour?
Round your answer to the nearest hundredths decimal place.
9514 1404 393
Answer:
2.05 hours
Step-by-step explanation:
Using the given equation with the given time, we have ...
55x +35(2.5) = 200
55x = 112.5 . . . . . . . . subtract 87.5
x = 2.05 . . . . . . . . . . divide by 55
The car spends 2.05 hours at 55 mph.

Find the surface area of the cuboid shown below
Answer:
Surface area of cuboid = 352 cm
Step-by-step explanation:
Given that:
Height of cuboid = 8 cm
Length of cuboid = 12 cm
Width of cuboid = 4 cm
Surface area = 2lw + 2lh + 2hw
Putting all the values;
Surface area = 2*12*4 + 2*12*8 + 2*8*4
Surface area = 96 + 192 + 64
Surface area = 352 cm
Hence,
Surface area of cuboid = 352 cm

If a triangle has angle A that is 70* and angle B that is 90* what is angle C?
Answer:
angle c = 20 °
Step-by-step explanation:
as sum of all sides of triangle is equals to 180°
If angle e and angle f are complementary if measure of angle e = 9x+22 and measure of angle f = 2x+24 fine measure of angle f
Answer: 32°
Step-by-step explanation:
Complementary angles are the ankea that are equal to 90° when we add them together. This will then be:
9x+22 + 2x+24 = 90
11x + 46 = 90
11x = 90 - 46
11x = 44
x = 4
Angle F = 2x + 24
= 2(4) + 24
= 8 + 24
= 32°
