If a 42.9 ft tall flagpole casts a 253.1 ft long shadow then how long is the shadow that a 6.2 ft tall woman casts?

We will have to use proportions:
$\frac{42.9}{253.1} = \frac{6.2}{x}$
Cross multiplying we get
$42.9x = 6.2 \times 253.1$
Now divide:
$x = \frac{6.2 \times 253.1}{42.9}$
Solve to tenths place we get
$x = 36.6$
The woman casts a 36.6 ft long shadow.

Answer the circled ones, Thanks

Answer:

1. 6, 4. 27s, 6. 11mn/ 7. 12(3x+2), 8. 3(2+x), 11. 2(x-2)

Step-by-step explanation:

the GCF is the highest factor that can go into each monomial, 27s factors are 27 and 1 as well as s, 57st factors are 26 and 2 as well as 57 and 1, with s and t. the highest factor is 27 with s, or 27s. the same thing applies with factoring monomias just take out the GCF and multiply it by what's left. 6 has factors of 6 and 1 as well as 2 and 3, 3x has factors of 3 and 1 with x take the common 3 out and your left with 3(2+1x) or 3(2+x).

Answer:

the answer is (x,y) = (6,6)

Step-by-step explanation:

1) first solve the equation for 2y

you should've gotten:

2y = -6 + 3x

5x - 2y = 18

2) substitute the value of 2y into the equation

5x - 2y = 18

so, 5x -(-6 + 3x) = 18

3) now solve 5x -(-6 + 3x) = 18

4) from that solving that equation, u should've gotten x = 6

5) now plug in 6 for x in the other equation, solve for y

( • stands for multiplication if u didn't know, we use this in higher levels of math so multiplication symbols and x variables aren't confused)

5 • 6 - 2y = 18

6) after solving for y in the previous equation, u should've gotten y = 6

7) now we know that x = 6 and y = 6, however it is always important to check if ur answer is correct by plugging in the x value y values u ended up with into the original system of equations.
