Answer:
k=69
Step-by-step explanation:
(plug in 69 instead of k)
69/3 = 23.
23+1=24
The ≥ sign means 21 has to be GREATER or EQUAL to 17.
Is it?
24≥17?
YES!
So, it works out.
Hope this helps.

The Mongolian Giant Sunflower produces seeds that are over 1 inch long, grow up to 18 feet tall, and flowers that are 1 ½ feet wide. Each flower head produces 1,000 seeds. You decide to harvest the seeds at the end of the season so that you can sell them the following spring. If you save 8 flowers for harvesting, how many seeds is that? Write your answer in scientific notation.
Answer:
8*10^3
Step-by-step explanation:
The Mongolian Giant Sunflower produces seeds that are over 1 inch long, grow up to 18 feet tall, and flowers that are 1 ½ feet wide. - All of this information is useless, all the question is asking is how many seeds do 8 flowers produce.
Each flower head produces 1,000 seeds. If you save 8 flowers for harvesting, how many seeds is that? - 1000*8 = 8000. 8000 is scientific notation is 8*10^3, as 10^3=1000, and 1000*8=8000 seeds.

Answer:
17, 17, 1 13/21
Answer:
1 13/21
Step-by-step explanation:
First, Multiply the 4 and 3 by 7 to get 28/21. Then Multiply the 2 and 7 by 3 to get 6/21. Add them up and you get 34/21. To convert, divide 34 and 21 to get one with the remainder of 13. The final answer is 1 13/21.
A population of caribou in a forest grows at a rate of 3% every year. If there are currently 208 caribou, which function represents the number of caribou in the forest in t years?
Answer:
f(x)=208^0.3x
Step-by-step explanation:
Think of this as a graph. You start out with 208 caribou, which is your y intercept, as it is there when the growth is 0.
The generic formula fr an exponential equation is a^x.
A represents your initial value. In this case, its 208
x represents the growth. In this case, it's 0.3%.
Your equation should be f(x)=208^0.3x

Answer:
y=2x+6
I started with the simplist equation for the first set (0,6) of y=X+6 and then tested it out for the second set (1,8) which didn't work. I then ajusted it so it would work with the second set by doing y=2x+6. Lastly, I tested this equation with all of the points and it worked for them all.

5/6 times 13 is 10 5/6. No
4 times 13 is 52. Yes
3/4 times 13 is 9 3/4. No
10/10 times 13 is 13. Yes
The expressions greater or equal to 13 are B and D.
What is an expression?An expression in math is a statement having minimum of two numbers, or variables, or both and an operator connecting them.
Given are expressions we need to determine expressions having values equal to or greater than 13,
So,
5/6 and 3/4 are numbers less than 1 if we multiply any number with them it will decrease its value,
So, the expression 4 x 13 and 10/10 x 13 will be the expressions having values equal to or greater than 13.
Hence the expressions greater or equal to 13 are B and D.

Solve for m.
−48=12(m+4)
Enter your answer in the box.
Answer:
-8
Step-by-step explanation:
First, you distribute the right side
-48 = 12(m+4)
-48 = 12(m) + 12(4)
Simplify:
-48 = 12m+48
Solve for m
-96 = 12m

141x + 50 + 4x = 340
What is x?
Answer:
x = 2
Step-by-step explanation:
141x + 50 + 4x = 340
=> 145x + 50 = 340
=> 145x = 290
=> x = 2
Hoped this helped.
Simplify both sides of the equation
141x+50+4x=340(141x+4x)+(50)=340(Combine Like Terms)145x+50=340145x+50=340Subtract 50 from both sides
145x+50−50=340−50145x=290Divide both sides by 145
[tex] = > \frac{145x}{145} = \frac{290}{145} [/tex]

Maria has already written Two-fifths of her 1,000 word essay. If she continues writing at the same pace of 6One-half words per minute, which expression shows the amount of time it will take her to write the rest of the essay?
1000 times two-fifths times 13/ 2
1000 times two-fifths divided by 13/ 2
1000 times three-fifths times 13 / 2
1000 times three-fifths divided by 13/2
Answer: B
Step-by-step explanation: Well use the process of elimination, there are no three-fifths in the equation so you can exclude options C and D, and then you take the remaining words left (600) and divide it by 6 and 1/2 to get how much time left. you wouldn't multiply it because that would increase the time which doesn't make sense.
A washing machine is filling up with water at a constant rate. The rate is Three-fourths of a gallon in 1 over 5 of a minute. Don calculated the unit rate to be 3 over 20 of a gallon per minute. What did he do wrong?
Answer:
First, you have to see how many gallons fill in a minute, obviously, so take 3/4 and divide it by 1/5, which gives 15/4. so you can see, don multiplied the two numbers instead of dividing, which is what he did wrong.Step-by-step explanation:
Answer from NukeExplosions1
Answer:
What he did wrong is that he multiplied the denominator wrong. it is supposed to be a 15. Don should re-calculate it to 3 over 15 of a gallon per minute.

A weather station on the top of a mountain reports that the temperature is currently 0°C and has been falling at a constant rate of 3°C per hour. What was the temperature:
1 hour ago?
3 hours ago?
Half an hour ago?
Answer:
For one hour ago, it would be 3 C, 3 hours ago, it would be 9 C, and half an hour ago, it would be 1.5 C.
Step-by-step explanation: It's quite straightforward. Since the temperature is dropping, and you want to find the temp. of earlier times, just add 3C to every hour (1.5 for a half) it was ago, to what the temperature currently is now. (0 C).
