A vehicle moving at a constant speed travels 45 miles in 3/4 hour. The driver thinks he will be late to a meeting that is still 65 miles away and that starts in 1.25 hours. Assume he maintains a constant speed. Find the driver's unit rate of speed and explain whether he was late or not. I REALLY need help!

Answers

Answer 1

Answer: ok so
speed=distance/time

find his speed in miles per 1 hour

3/4=0.75
s=d/t
s=45/0.75
s=60/1
s=60mph

starts in 1.25 hours
if he takes all that time, will he be late, on time, or early

multiply
60mph
1.25 hours
60 times 1.25=75
in 1.25 hour he can travel 75miles

he needs to only travel 65
75>65
he will make it
not late, he is early

Answer 2

Answer: 1) we calculte the driver´s unit rate of speed.
s=speed
d=distance
t=time.

s=d/t

45 miles------------------3/4 hour
x----------------------------- 1 hour

x=(45 miles * 1 hour) / (3/4 hour)=60 miles.

speed or rate=60 miles / 1 hour.

2)we calculate the distance traveled at 1.25 hour.

distance=rate * time

distance=(60 miles /1 hour) * 1.25 hour=75 miles.

Answer: the driver would´t go late, because, the distance is 65 miles, and he can travel 75 miles if he drive with that speed .

Need help Math 8 lesson 10.4 . I know that i have to keep the base and that the top turns into a one.

Answers

There are two ways to do this, but I'm only gonna use the first way.
First, to move the 2^-8 to the numerator and combine the exponents, and keep the same base and you get 2^ 14. Next, to divide powers, you subtract the exponents and keep the base. So 2^14/2^10 gives you 2^4. If you want to simplify it further, you'll get 16.

so you add the exponents and then you multiply the sum by the base number. that becomes your denimator. then you solve the numerator and your answer becomes the new numerator of your new denominator. Finally you simplefy

Step 1 :Pulling out like terms :

1.1 Pull out like factors :

2p + 8 = 2 • (p + 4)

Equation at the end of step 1 : Step 2 :Equations which are never true :

2.1 Solve : 2 = 0

This equation has no solution.
A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2 Solve : p+4 = 0

Subtract 4 from both sides of the equation :
p = -4

One solution was found : p = -4

your bag`s weigh is 22 pound right now so you still can add 40 - 22 = 18 pounds. So you can right this inequality:
x + 22 ≤ 40
so x is the number of pound that you can add:
x ≤ 40-22
x ≤ 18 :)))

Find 30% of 26. I need help really bad.

Answers

To find a percentage of a number, you multiply the number by the decimal form of the percentage. The decimal form of 30% is 0.3, so we multiply 26 by 0.3:

26 x 0.3 = 7.8

30% of 26 is 7.8

answer is 7.8 because if u use a claculator and do 30%*26 it will equal 7.8

From the picture below, what is the measure of DCF?

Answers

Answer:

236°

Step-by-step explanation:

The central angle is equal to the measure of the arc subtending it.

arc GF = 180° - (90 + 34)° = 180° - 124° = 56°, thus

arc DCF = arc DG + arc GF = 180° + 56° = 236°
