Answers

Answer:

7/21+9/21=16/21

Hope it helps

Have a good day

Answer:

16/21

Step-by-step explanation:

[tex]\frac{3}{7}+\frac{1}{3}[/tex]

First, make them have a common denominator.

The least common factor of 7 and 3 is 21, so you can do

3/7 * 3/3 = 9/21

1/3 * 7/7 = 7/21

The new expression would be:

[tex]\frac{9}{21}+\frac{7}{21}[/tex]

[tex]\frac{16}{21}[/tex]

So the answer is 16/21

Question 4 (Essay Worth 10 points)
(06.05 MC)

Iris is a botanist who works for a garden that many tourists visit. The function f(s) = 2s + 25 represents the number of flowers that bloomed, where s is the number of seeds she planted. The function s(w) = 25w represents the number of seeds she plants per week, where w represents the number of weeks.

Part A: Write a composite function that represents how many flowers Iris can expect to bloom over a certain number of weeks. (4 points)

Part B: What are the units of measurement for the composite function in Part A? (2 points)

Part C: Evaluate the composite function in Part A for 30 weeks. (4 points)

Answers

Answer:

(a) f (w)=50w+25

b number of flowers for a given number of weeks

Step-by-step explanation: hope this helps :)

A function is said to be a composite function when a function is written in another function. The composite function that represents the number of flowers is [tex]f(w) = 50w + 25[/tex] and the number of flowers for 30 weeks is 1525.

Given that:

[tex]f(s) = 2s + 25[/tex]

[tex]s(w) = 25w[/tex]

The number of flowers to bloom over w weeks is calculated using the following composite function: f(w)

[tex]f(s) = 2s + 25[/tex]

Replace s with s(w)

[tex]f(s(w)) = 2(s(w)) + 25[/tex]

Substitute [tex]s(w) = 25w[/tex]

[tex]f(s(w)) = 2(25w) + 25[/tex]

[tex]f(s(w)) = 50w + 25[/tex]

Hence:

[tex]f(w) = 50w + 25[/tex]

The units of the measurement of f(w) is flowers

The number of flower for 30 weeks means:

[tex]w = 30[/tex]

So, we have:

[tex]f(30) = 50 \times 30 + 25[/tex]

[tex]f(30) = 1525[/tex]

Hence, the number of flowers for 30 weeks is 1525

Answers

Answer:

Step-by-step explanation:

19+1 additional for each guest so there are 13 guests so 13+1= 14 so 14+19= 33

hope this helps or maybe it could be that you have to times it so here it is.

13 times 1 = 13 so we still have 19 so 19+13= 32 but i think it is 33 trust me. :) tell me if this was right thx.

Answer is $32

The initial cost without inviting any guest is $19 which implies that after she invited 13 guest at the cost of $1 for each guest then the total cost will be the addition of $19 and $13 which is $32

The sides of a 45°-45°-90° triangle are in the ratio 1:1:√2

The side opposite the 90° angle is 12√2.

a = c = (12√2)/√2 = 12

The sides of a 30°-60°-90° are in the ratio 1:√3:2.

The length of the side opposite the 30° angle is 12 units.

d = length of side opposite 60° angle = 12√3 units
