Answer:
a₁₈ = 113
Step-by-step explanation:
There is a common difference d between consecutive terms
d = 49 - 45 = 53 - 49 = 57 - 53 = 4
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 45 and d = 4, then
a₁₈ = 45 + (17 × 4) = 45 + 68 = 113
For this problem, if we used b to represent your base angle measurement, you would add 8b+2b and set it equal to 180. This is because the measure of the vertex angle is 8 times the base angle measurement, so we had to multiply b by 8. We also had to add it to the other angle measures, so the other angle measures are represented as 2b since they are the same length. We then have to set this equal to 180 since that measures of a triangle must add up to 180. Then we combine like terms on our “b” side to get 10b=180. Then we divide both sides by 10 and we get b=18, which is the measure of our base angle.
Answer:
B. 130 70
Step-by-step explanation:
Agent B sold the highest number (53.85% ) of houses given the number of listed houses.
Find the percentage of houses each agent sold.
For A
x/100 * 150 = 75
cross multiply and find x, that would be 50%
For B
x/100 * 130 = 70
cross multiply and find x, that would be 53.85%
for C
x/100 *145 = 75
cross multiply and find x, that would be 51.72%
Answer:
472
Step-by-step explanation: First subtract the additional cost from the overall cost, than you find the value of the bench by dividing by 2, than add the additional cost to the price of the bench to find the total cost of the Garden Table.
897-47=850
850 divided by 2 = 425
425 + 47 = 472
Answer:
2 1/4 hours
Step-by-step explanation:
Each night, he read for 3/4 hours = 3*60/4 = 45 minutes.
He read for 3 days.
So in total, he read for:
3*45 = 135 minutes.
135 minutes is 2 hours and 15 minutes. 15 minutes is 1/4 of an hour.
So the correct answer is:
2 1/4 hours
