Answer:
Diameter= 6.15
Step-by-step explanation:
Like the radius explanation but multiply the answer by 2.
Check the picture below.
the idea being that sides of 2.5 andd 8 are fixed, what's are the possible lengths of "x"?
well, if we open the fixed sides, we'll end up with a 3rd side of 2.5 + 8 = 10.5, however if "x" is ever 10.5, the figure will become a flat-line and we'd be losing the triangle.
and if we close the fixed sizes, the longest "x" could be is 8 - 2.5 = 5.5, but the same, it can't be 5.5 exactly otherwise the figure will turn to a flat-line.
5.5 < x < 10.5.
Answer:
a) 11mph
b) 6mph
c) 25 miles
Step-by-step explanation:
She can run 12 miles in 2 hours.
She can bike 33 miles in 3 hours.
a) What is Jennifer's biking speed?
Divide:
b) What is Jennifer's running speed?
Divide:
c) Jennifer biked for 2 hours and then ran for 30 minutes. What distance did she cover?
She bikes 11 miles per hour.
2 hours would be = 11mi * 2 = 22miles
She runs 6 miles per hour.
30 minutes or 1/2 hour would be = 6mi * 1/2 = 3 miles
Add these distances.
22+3=25 miles
∠PXS = (180 - 106) ÷ 2 // isosceles triangle
∠PXS = 37°
∠XQR = 180 - 106 //parallelogram
∠XQR = 74°
∠RXQ = 74° //Isosceles triangle
∠SXR = 180 - 37 - 74 // Adjacent angles on a straight line
∠SXR = 69°
------------------------------------------
Answer: ∠SXR = 69°

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!
