The ramp on the back of a moving van is 3ft high and rises at an angle of 25° . how long is the ramp . round to the nearest foot.

Answers

Answer 1

Answer: Remember Soh Cah Toa (say it aloud, this is how I remember it)- Sin(a)=Opposite/Hypotenuse, Cos(a)=Adjacent/Hypotenuse, and Tan(a)=Opposite/Adjacent. Each of these terms is related to the angle you're working with
So for your problem:
3 ft is opposite of the angle so to calculate the hypotenuse=3/Sin(25)

Answer:

6 hours

Step-by-step explanation:

Set up a proportion:

15kg/5 hrs = 18kg/x hrs

Cross multiply:

5(18)=15x

90 = 15x

Divide by 15:

90/15 = x

6 = x

Rectangle ABCD is similar to rectangle EFGH. Side CD is proportional to side ___.A.EF
B.FG
C.GH
D.HE

Answers

If the rectangle ABCD is similar to rectangle EFGH, side CD is proportional to the side

C. GH

The order of the letters in naming the rectangle gives us which sides are adjacent in rectangle and which sides correspond to the other rectangle.

Answer: C. GH

Step-by-step explanation:

Given: Rectangle ABCD is similar to rectangle EFGH.

Side AB is corresponding to EF [First two letters]

Side BC is corresponding to FG [Middle two letters]

Side CD is corresponding to GH [Last two letters]

Side AD is corresponding to EH [First and last letter]

We know that the corresponding sides of the similar figures are proportional.

Therefore, we can see that Side CD is proportional to side GH.

1.Read the complete problem before answering. Teresa bought gallons of chocolate milk at the dairy farm. Chocolate milk cost $4.50 a gallon. How much did Teresa spend on the milk?

A student solved the problem this way.

gallons = 2.5 gallons
Let n represent the amount Teresa spent on the milk.
n = 2.5 × $4.50
n = $11.25
Teresa spent $11.25.

I think it'll be better if you put one question at a time....

( I'm gonna go and follow it like the last problem we did, where we assume the amount bought or made in the 1st part of a problem will be the same amount in the second part of the problem. )

1. $4.6 * amount/pounds bought in total

( Since in part 1, Teresa bought 2.5 gallons... )

2.5 pounds of red sand and 2.5 pounds of brown sand = 5

$4.6 * 5 =$23

2. ( Giles had 2 quarts in total )

2 quarts of ginger ale + 2 quarts of lemonade= 4 quarts, and 1 quart = 2 pints, so 8 pints

3. ( 4.33 yards since in the first part, Mark had 13 feet, and 13 feet= 4.33 yards )

So we assume Julie has 2 pieces of Velcro and each are worth 13 feet ( like Mark ). 13 * 2 = 26 feet

4. ( Patty had 9 quarts, and one gallon = 4 quarts, so she had 2.25 gallons )

So, we assume 8 in the morning and 9 during lunch, since the part 1's answer was 9. 9*2=18 hours, 18 hours = 1080 minutes
