Answer:
Length of beads altogether in the necklace = 3.75 cm
Step-by-step explanation:
Length of the beads used in a necklace = 
cm
Number of beads used in the necklace = 3
Therefore, length of beads in the necklace = Length of each bead × Number of beads used
= 
= 
= 3.75 cm
Length of the beads altogether in the necklace = 3.75 cm
66 + 149 = 215
215/2 = 107.5
107.5 is the average.
Answer:
HL (Hypotenuse Leg)
Step-by-step explanation:
You have BC=CD (Because of reflexive property), AC=DC, and measure of BAC is equal to the measure of BDC, which is 90 degrees. Since these triangles are right and they have a hypotenuse and a leg congruent, you can say that they are congruent because of HL.
Answer:
140 minutes
Step-by-step explanation:
After 28 mins you've gone 4 miles, assuming this rate is constant and you dont slow down or speed up, in order to get to 20 miles you will have run 5x as much (20/4 = 5), thus 5x the amount of time (28x5).
20/4 = 5
5x28 = 140
