Answer:

22 3/4 ft

Step-by-step explanation:

The diagram seems to show a 6 1/2 ft person casting a 9 ft shadow at the same time a flagpole is casting a 31 1/2 ft shadow. You want the height of the flagpole.

<h3>Proportion</h3>

Shadow lengths are presumed proportional to the height of the object making them. This means ...

h/(31 1/2) = (6 1/2)/9 . . . . . all lengths in feet

Multiplying by 31 1/2, we get ...

h = (31 1/2)(6 1/2)/9 = (819/4)/9 = 91/4

h = 22 3/4 . . . . ft

The flagpole is 22 3/4 feet tall.

Anyone know how to solve this? I know the answers for j and g but I need help finding h, f and i!!!!!!! PLS HELP TY! (SEE ATTACH

Juliette [100K]

Step-by-step explanation:

RISE/RUN is an important rule...

f = $\frac{50}{3}$ = around 16.7 (3.s.f)

h = $\frac{(70-50)}{(6-4)}$ or $\frac{20}{2}$ = 10

i = $\frac{30}{1}$ = 30

What is the solution to 6x+5y=19 4x+6y=10

igor_vitrenko [27]

Answer:

The value of x is 4 and y is -1 .

Step-by-step explanation:

First, you have make any term to have the same coefficient. So I will choose x term :

$6x + 5y = 19 - - - \times 2$

$12x + 10y = 38 - - - (1)$

$4x + 6y = 10 - - - \times 3$

$12x + 18y = 30 - - - (2)$

Next, you have to solve it by Elimination method :

$(1) - (2)$

$12x + 10y - 12x - 18y = 38 - 30$

$- 8y = 8$

$y = - 1$

$substitute \: y = - 1 \: into \: (1)$

$12x + 10( - 1) = 38$

$12x - 10 = 38$

$12x = 38 + 10$

$12x = 48$

$x = 4$
