Answer:
The missing information is: how many hours does she works per day?
Step-by-step explanation:
Amount Jenna makes per hour babysitting = $8
Number of days she works per week = 3 days
The missing information is: how many hours does she works per day ?
ASSUME she works 24 hours per day for 3 days
Total amount Jenna earns in a week = $8 × 24 hours × 3 days
= 8 × 24 × 3
= $576
First, subtract to get the difference.
2.85 – 2.78 = 0.07
Next, divide 2.78 by 100
2.78 ÷ 100 = 0.0278
So, 0.0278 is 1%. Divide 0.07 by 0.0278 to get the answer.
0.07 ÷ 0.0278 ≈ 2.518
2.518 ≈2.5
Therefore, the percentage increase is approximately 2.5% (that's the answer).
Hope this helps!
Answer: You left out half the question so
Step-by-step explanation:
if you're looking for chance of x houses having a tv, then .6^x is your formula,
if you're looking for chance of x houses not having a tv, then .4^x will find it
Both formulas only apply if you're looking at specific homes, since your question is incomplete I can only guess at what your answer should be.
If the question is, "What is the scale factor." That would be a scale (factor) of 2.
Answer:
A, 14
Step-by-step explanation:
Assuming that she has a total of d dollars, and spends half of it, then we have 1/2d. She then spends <em>another</em> 6 dollars, and therefore we would subtract. She is left with one dollar.
1/2d-6=1
Working backwards, we can solve for d, her total amount of money:
1/2d=7
d=14
