Answer:
She runs for 1.6 hours
Step-by-step explanation:
For this, one way to do it is to just set 1 hour over 4 miles equal to x hours for 6.4 miles. The reason this is done is because if the speed is constant that means the rate stays the same, which means the ratio of miles to hours should always be the same, so the two ratios must be equivalent.
1/4 = x/6.4
Multiply both sides by 6.4 to get x by itself:
6.4/4 = x
1.6 = x
Hope that helps!
Answer:
Width = 25
Length = 58
Step-by-step explanation:
Let the width = w
Length = 2w + 8
2(w + 2w + 8) = 166 Combine terms in the brackets
2(3w + 8) = 166 Divide both sides by 2
(3w + 8) = 83 Subtract 8 from both sides
3w = 83 - 8
3w = 75 Divide by 3
w = 25
L = 2*25 + 8 Find the Length
L = 50 + 8 = 58
HI, a right triangle is a triangle that has a 90 degree angle. the angle look similar to the letter l capitalized L then to complete this you will draw a diagonal line connecting the two points on the 90 angle. I Hope this could help.
The answer would be 2 and 3/10. To find this, I multiplied 1 and 1/2 by 2 and 3 and 1/2 by two. So, now to make 3 dozen muffins, a recipe uses 7 cups of flour. I did this because obviously dividing 3 and 7 are easier and its hard to find how many cups of flour make 1 dozen when you have the equation for 1 and 1/2 because 1 doesn't go into 1 and 1/2 equally. Now, with the new equation, I can just divide 3 by 3 to get 1 (which would be 1 dozen muffins) and also divide 7 by 3 to get 2.3. 2 is obviously the whole number in the mixed number and .3 is the fraction, which is 3/10. Hope this helps!
Answer:
33.3 ft
Step-by-step explanation:
Draw a picture, you should see that a right triangle is formed from the flag and shadow. Apply pythagorean theorem. See attached image for work out.
