find the 19th term of the arithmetic sequence d=5 a1=2
Answer:
92
Step-by-step explanation:
nth term = a₁ + (n - 1)d
19th term = 2 + (19 - 1) * 5
= 2 + 18*5
= 2 + 90
= 92

The angle of elevation from a boat to the top of a lighthouse is 50°.
If the boat is 150 feet from the base of the lighthouse, how tall is the lighthouse?
Round answer to the nearest foot.
9514 1404 393
Answer:
179 ft
Step-by-step explanation:
The applicable trig relation is ...
Tan = Opposite/Adjacent.
The height of the lighthouse is the opposite side of the right triangle. The adjacent side to the angle of elevation from the boat is the distance to the lighthouse base. Then ...
tan(50°) = height/(150 ft)
height = (150 ft)(tan(50°)) ≈ 178.76 ft
The height of the lighthouse is about 179 feet.

Michelle compares 5.8 x 106and 2.32 x 107. What steps could she use to compare the two numbers?
Answer:
5.8 × 10^(6) is greater.
Step-by-step explanation:
The 2 numbers she wants to compare are;
5.8 × 10^(6) and 2.32 x 10^(7)
Now,for her to compare easily both numbers will need to have the same powers of 10.
To this effect, let's convert the power of ten of the second number to the power of 6.
We will divide by 10 to get it.
Thus; 2.32 x 10^(7) ÷ 10 = 0.232 × 10^(6)
Comparing 0.232 × 10^(6) to 5.8 × 10^(6), we can see that they have same power of 10 but the greater number that precedes the power of 10 is 5.8.
Thus, 5.8 × 10^(6) is greater.

Work out the fraction that is halfway between 1/2 and 1 1/4
Answer:
The fraction that is halfway between 1/2 and 1 1/4 is: 5/8
Step-by-step explanation:
Given the fractions
1/2 and 1 1/4
In order to determine the fraction that is halfway between 1/2 and 1 1/4 first, we need to add the fractions and then divide the result by 2.
1)
Add the numbers
[tex]\frac{1}{2}\:+\:1\frac{1}{4}[/tex]
as 1 1/4 = 3/4, so
[tex]\frac{1}{2}\:+\:1\frac{1}{4}=\frac{1}{2}+\frac{3}{4}[/tex]
Apply fraction rule: [tex]\frac{a}{c}+\frac{b}{c}=\frac{a+b}{c}[/tex]
[tex]=\frac{2+3}{4}[/tex]
[tex]=\frac{5}{4}[/tex]
2)
Divide by 2
[tex]\frac{5}{4}\div \:2[/tex]
Convert element to fraction: [tex]2=\frac{2}{1}[/tex]
[tex]\frac{5}{4}\div 2=\frac{5}{4}\div \:\frac{2}{1}[/tex]
Apply fraction rule: [tex]\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}[/tex]
[tex]=\frac{5}{4}\times \frac{1}{2}[/tex]
Multiply fractions: [tex]\frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}[/tex]
[tex]=\frac{5\times \:1}{4\times \:2}[/tex]
[tex]=\frac{5}{8}[/tex]
Conclusion:
Therefore, the fraction that is halfway between 1/2 and 1 1/4 is: 5/8

You rent an apartment that costs $1400 per month during the first year, but the rent
is set to go up $180 per year. What would be the monthly rent during the 5th year of
living in the apartment?
The rent in the 5th year is $2120.
What is Arithmetic?The mathematical branch known as arithmetic deals with the study and application of numbers, their relationships, and mathematical observations. We can find the amount regularly increasing by using arithmetic.
As per the given data:
Cost of the apartment per month during the first year is given, also the increase in rent every year is given.
We have to find out the monthly rent during the 5th year of living in the apartment.
For finding out the monthly rent during the 5th year of living in the apartment:
Rent in first year + Increase in rent in each year × (5 - 1)
= 1400 + 180 × 4
= 1400 + 720
= $2120
The rent in the 5th year is $2120.
Hence, The rent in the 5th year is $2120.

Lauren invests money in an account paying simple interest. She invests $50 and no money is added or removed from the investment. After one year, she has $50.50. What is the simple percent interest per year?
Based on the amount invested and the amount it grew to, the simple interest rate is 1%.
Lauren invested $50 and got $50.50 after a year.
What is the Simple Interest rate?This rate can be found by the formula:
= (Difference in investment in year 1) / Amount invested x 100%
Solving gives:
= (50.50 - 50) / 50 x 100%
= 1%

Margo is practicing her free throws for basketball
tryouts. To make the team she has to make at least
80% of her free throws. How many free throws does
she have to make if she attempts 20 shots?
Answer:
16
Step-by-step explanation:
Well if you think about it, if she has a total of 10 attempts she has to make 8 of them to make it on the team. Now the total attempts is double so we double the number of throws she needs to make in order to make the team so to do this we would do 8*2 which is 16. She needs to make 16 throws to make it on the team.

Jordan's dog weights p pounds. Emmett's dog weighs 50% more than Jordan's dog.
Which expressions represent the weight, in pounds, of Emmett's dog?
the expression fir the weight of Emmett's dog is 1.25p
Step-by-step explanation:
The weight of Jordan's dog is p pounds.
And it has been given that Emmett's dog weighs 25% more than Jordan's dog.
Hence, 25% of weight of Jordan's dog is
25% of p
= 0.25p
Now, since, Emmett's dog weighs 25% more than Jordan's dog.
Hence, the weight of Emmett's dog is given by
Weight of Jordan's dog + 25% of weight of Jordan's dog
= p + 0.25p
=1.25 p
Therefore, the expression fir the weight of Emmett's dog is 1.25p

The price of bananas can be determined by the equation P=0.25n, where P is the price and n is the number of bananas. What is the constant of proportionality (unit rate)?
Given:
The price of bananas can be determined by the equation P=0.25n, where P is the price and n is the number of bananas.
To find:
The constant of proportionality
Solution:
We have,
[tex]P=0.25n[/tex] ...(i)
where P is the price and n is the number of bananas.
Price P is directly proportional to the number of bananas. So,
[tex]P\propto n[/tex]
[tex]P=kn[/tex] ...(ii)
Where, k is the constant of proportionality.
On comparing (i) and (ii), we get
[tex]k=0.25[/tex]
Therefore, the constant of proportionality is 0.25.
