If a 6 foot long person casts a 2 foot long shadow or 1/3 of height then it is 109 feet tall or 328/3=109.3333

714, because the unit rate is three and three times 328 is 714

Consider the series.

Serga [27]

Put 1

$\\ \rm\Rrightarrow \left(\dfrac{3^{1+1}}{3(1)+1}\right)$

$\\ \rm\Rrightarrow 3^2/4=9/4=2.2$

Put 2

$\\ \rm\Rrightarrow \left(\dfrac{3^{2+1}}{3(2)+1}\right)=3^3/7=27/7=3.8$

R is

3.8/2.2=19/11

Its greater than 1 .

So diverge series.

If 400ml of milk is used for 8 pancakes then how much is used for 6

Naddik [55]

To solve this equation, you will need to set up a proportion where you set two fractions equal to each other.

Let x = the unknown amount of milk

$\frac{400}{8} = \frac{x}{6}$

You would then crossmultiply and solve for x.

8x = 400(6)

8x = 2400

x = 2400/8

x = 300

You will need 300 mL of milk to make 6 pancakes if you previously needed 400 mL to make 8 pancakes.

whitney has a coin jar with a small collection of nickels and dimes. there are 69 coins in the jar. they have a value of $5.90.

Anastaziya [24]

Answer:

The number of nickels in the jar is 20.

The number of dimes in the jar is 49.

Step-by-step explanation:

Let us assume the total number of nickels = x

The total number of dimes = y

Total coins = 69 coins

⇒x + y = 69

Now as we know:

1 Nickel = $0.05

and 1 Dime = $0.10

⇒ The value of x nickels = x ( $0.05) = 0.05 x

and The value of y nickels = y ( $0.10) = 0.10 y

Total amount in jar = $5.90 ⇒0.05 x + 0.10 y = $5.90

So, the given system of equation is

x + y = 69 .............. (1)

0.05 x + 0.10 y = 5.90 ....... (2)

Substitute the value of y = 69 - x in (2) , we get:

0.05 x + 0.10 y = 5.90 ⇒ 0.05 x + 0.10 ( 69 - x) = 5.90

or, 0.05 x + 6.9 - 0.10 x = 5.90

or, - 0.05 x = -1.00

⇒ x = 1/0.05 = 20, or x = 20

⇒ y = 69 - x = 69 - 20 = 49

Hence the number of nickels in the jar is 20

and the number of dimes in the jar is 49.
