First multiply the exponents. You will get 3 to the power of 12: 531441. Multiply this by 30 and you have 15943230
Answer:
<h3>#1</h3>
- tangent = opposite leg / adjacent leg
- tan ∠F = DE/ EF
- tan ∠F = 24/7
<u>Option D</u>
<h3>#2</h3>
Sine and cosine are same for complementary angles.
- Complementary of 67° is 90° - 67° = 23°.
- sine 67° = cosine 23°
Using the probability concept, we have that:
- The probability that the student only plays football is: (c) 13 /33.
- The probability that the student plays baseball, but not football is: (d) 8/33.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
The total number of students is given by:
26 + 3 + 9 + 10 + 6 + 5 + 7 = 66
Of those, 26 play only football, hence the probability is:
p = 26/66 = 13/33
Which means that option c is correct for question 19.
Of those same 66 students, 9 + 7 = 16 play baseball but not football, hence the probability is:
p = 16/66 = 8/33
Which means that option d is correct for question 20.

#SPJ1
Answer:
8 Weeks
Step-by-step explanation:
First let's collect the given data:
• <u>Class A:</u>
- Starts at 8 cm
- grows at 3.5 cm/week
• <u>Class B:</u>
- Starts at 10cm
- grows at 3.25 cm/week
Class B's plant starts out 2 cm taller and Class A's plant grows 1/4 cm faster. So, to find when these two will be at an equal height, divide 2 cm by 1/4.
2 ÷ 1/4 =
2 × 4/1 =
2 × 4 =
8
It will take 8 weeks for the plants to be at an equal height.
Hi there
Payment per year
1,000×12months=12,000
total payment over the lifetime of the loan.
12,000×10years=120,000
Hope it helps
