From the given, we expressed the time that each of the team members ran in mathematical expression.
Reggie = 57.12 seconds
Alvin = 57.12 + 2.45 seconds = 59.57 seconds
Jose = 57.12 - 3.81 seconds = 53.31 seconds
We then sum up all the time we calculate to determine the total time for the team. The answer is therefore 170 seconds.
The rhombus is shown in the diagram below
The length of one side of the rhombus is 5 units, hence all the other sides are also 5 units each.
Answer:
(x = -20) if what your saying is 6 = -2x - 4 and (x = -16) if what your saying is x = -2 x 6 - 4
Step-by-step explanation:
Answer:
KL = 50
Step-by-step explanation:
∆JML is similar to ∆JNL. it follows that:
[tex] \frac{JM}{JN} = \frac{JL}{JK} [\tex]
JM = 4 + 20 = 24
JN = 4
JL = 10 + KL
JK = 10
Plug in the values
[tex] \frac{24}{4} = \frac{10 + KL}{10} [\tex]
[tex] 6 = \frac{10 + KL}{10} [\tex]
Multiply both sides by 10
[tex] 6*10 = \frac{10 + KL}{10}*10 [\tex]
[tex] 60 = 10 + KL [\tex]
Subtract 10 from each side
[tex] 60 - 10 = KL [\tex]
[tex] 50 = KL [\tex]
KL = 50
Answer:
29
Step-by-step explanation:
(1.2 x 10-4) + (2.4 x 10-3)
Simplify
1.2 x 10- 4 = 8
2.4 x 10- 3 = 21
Add both sums to get 29!
SCIENTIFIC NOTATION
2.9 x 10 to the 1st power
Move the decimal over to make a number less than ten, so that makes 2.9 and 10 to the 1st because you moved the decimal once! Hope this is better
