Help please??????????

Mathematics
1 answer:
Ostrovityanka [42]3 years ago
7 0

Step-by-step explanation:

Since <em>a</em> is the final altitude after <em>t</em> minutes, we can plug in 21,000 for <em>a</em> in the given equation.

21,000 = 3400t + 600

Solve for t.

20,400 = 3400t

t = 6 minutes

35/40 reducing fractions
laila [671]

Answer: 7/8

What you have to do here is to find the highest number which can be divided by both. Or you have to divide both the numerator and denominator until it can not be divided by any number anymore. You can do this by finding the highest common factor (<u>HCF)</u> of both the number, 35 and 40.

Highest Common Factor: HCF of two or more numbers is the greatest factor that divides the numbers. For example, 2 is the HCF of 4 and 6.

So, the highest number which divides 35 and 40, is 5. Now 35 divided by 5 is 7 and 40 divided by 5 is 8. The final answer is 7/8 and there is no more numbers which can divide both of them by a specific number.

Which of these tables is a non linear function
adoni [48]

Answer:

C

Step-by-step explanation:

Because on all the graphs all the numbers on the Y side are essentially adding one.  With the 3rd graph, it goes from 17 to 19, skipping 18.  Therefore it is not linear.

If K is the midpoint of JL, JK=9x-1 and KL=2x+27, find JL.
ratelena [41]

Answer:

The answer is B. 70

Step-by-step explanation:

First, since K is the midpoint of line segment JL, JK must equal KL.

So, set 9x-1 = 2x+27 and solve.

7x=28 so x=4

Then, since they are asking for JL, using x=4, add together JK and KL.

So, 9x-1+2x+27 = 11x+26 = 11(4) + 26 = 44+26 = 70
