New grass seeds grow rapidly. A grass seed has grown to 12 millimeters tall. Tomorrow it will

1 answer:

5 0

The sequence is 11n+1 as the difference between each number is 11 and if you substitute 1 for n, you must add 1 to 11 to make 12. This sequence works for the other numbers as well.
To find out the height of the plant on the 15th day, just substitute 15 for n:
(11 x 15)+1=166mm is the height of the plant in 15 days.

Jason had three more than four times the amount of money that Jeff has. Together they have $72. How much money does each person

adelina 88 [10]

Answer:

Jason has $58.20 and Jeff has $13.80.

Step-by-step explanation:

Let x represent the amount of money Jason has, and y represent the amount of money Jeff has.

We know that together they have $72. So, we can write the following equation:

$x+y=72$

We know that Jason has three <em>more</em> than four <em>times</em> the amount of money Jeff has. So:

$x=3+4y$

This is a system of equations. We can solve it by using substitution. Let's substitute the second equation into the first. This yields:

$(3+4y)+y=72$

Combine like terms:

$5y+3=72$

Subtract 3 from both sides:

$5y=69$

Divide both sides by 5:

$y=69/5=\$13.80$

So, Jeff has $13.80

We know that Jason has three more than four times the amount of money Jeff has.

Therefore, Jason has:

$x=13.8(4)+3$

Multiply and add:

$x=\$58.20$

So, Jason has $58.20 and Jeff has $13.80.

And we're done!

Jacob is 5 and 5 sixths feet tall. and Linda is 5 and 1 fourth . How much taller is Jacob?

devlian [24]

Jacob=5 5/6 ft
Linda=5 1/4

So to find out the difference, we first have to make the fractions equivalent.

5/6x2/3=10/12
1/4x3/3=3/12

Now we subtract.

5 10/12-5 3/12
=7/12

Jacob is 7/12 ft taller than Linda.

Find the side indicated by the variable. Round to the nearest tenth.

zepelin [54]

Answer:

b ≈ 25.6

Step-by-step explanation:

From the figure attached,

By applying tangent rule in the given triangle,

tan(32°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

tan(32°) = $\frac{16}{b}$

b = $\frac{16}{\text{tan}(32)}$

b = $\frac{16}{0.62487}$

b = 25.605

b ≈ 25.6
