A car can travel 275 miles in 5 hours. Find the average speed in miler per hour.(please show steps!)

Answers

Answer 1

Answer: you just divide 275 with 5 so five cant to into 2 so you add the 7 down that will equal 5 and you subtract 25 because 5 cant go into 27 and that equals 2 you then bring down the five and it will make 25 5 mutiplied by 5 equals 25 so it would make 55 PLUS to check multiply 55 with 5=275 <3

Answer 2

Answer: 275/5=55
The average speed is 55 mph.

The baby sleeps from 9pm to 5am. How many hours does the baby sleep?

Answers

Answer: 8 hours.

Step-by-step explanation:

If the baby sleeps from 9pm to 5am, you will count. 9pm-12am is 3 hours of sleep. if you add 5 more hours, (12am+5 hours) it equals 5am. 5hours + 3hours is 8 hours.

Answer: 8 hours

Step-by-step explanation:

if you add 9+5 you will get 14 but if you count it like you would for hours it would be 9-10-11-12-1-2-3-4-5

7. acute means all angles are less than 90
right triangle mean that one angle is 90 degrees
it is not posible for all angles to be less than 90 and one angle is 90 so this is not possible

180 degrees per triangle
3 angles

13 POINTS.+Betsey is 11 years older than Waldo. Betsey's age is 15 years less than three times Waldo's age. The system below models the relationship between Betsey's age (b) and Waldo's age (w):

b = w + 11
b = 3w − 15

Which of the following methods is correct to find Betsey's and Waldo's age?
Solve w + 11 = 3w − 15 to find the value of w.
Solve b + 11 = 3b − 15 to find the value of b.
Write the points where the graphs of the equations intersect the x-axis.
Write the points where the graphs of the equations intersect the y-axis.

Answers

Answer:

Option 1st is correct

Solve w + 11 = 3w − 15 to find the value of w.

Step-by-step explanation:

Here b represents the Betsey's age and w represents the Waldo's age

As per the statement:

Betsey is 11 years older than Waldo. Betsey's age is 15 years less than three times Waldo's age.

The system below models the relationship between b and w:

$b = w+11$

$b = 3w-15$

Equate these equations to solve for w, we have;

$w+11 = 3w-15$

Add 15 to both sides we have;

$w+26= 3w$

Subtract w from both sides we have;

$26= 2w$

Divide both sides by 2 we have;

13 = w

w = 13 years

Substitute in b = w+11 we have;

b = 13 +11 = 24 years.

b = 24 years

Therefore. following methods is correct to find Betsey's and Waldo's age is:

$w+11 = 3w-15$

$w + 11 = 3w - 15 \n 2w=26 \n w=13 \n b = w + 11 \n b = (13) + 11=24$
