3 0

Answer:

3.1 feet

Step-by-step explanation:

Use the Pythagorean Theorem to find 0.5x and then multiply it by 2 to find x.

1.4²+b²=2.1²

1.96+b²=4.41

b²=2.45

b= $\sqrt{2.45}$

b≈1.56524758

x≈1.56524758×2

≈3.13049517

≈3.1 ft

Boatesville is 65 3/5 kilometers from Stanton. A bus traveling from Stanton is 24 1/3 kilometers from Boatesville. Write an equa

Elena L [17]

Distance the bus has traveled :

$65 \dfrac{3}{5} - 24\dfrac{1}{3}$

$= 65 \dfrac{3 \times 3 }{5 \times 3} - 24\dfrac{1 \times 5}{3 \times 5}$

$= 65 \dfrac{9 }{15} - 24\dfrac{5}{15}$

$= 41 \dfrac{4 }{15} \text { km}$

How do I do this ? I don’t understand logarithm

ale4655 [162]

Hello from MrBillDoesMath!

Answer:

x = 19

Discussion:

Both sides are logarithms to the same base, namely 20 , which implies the expressions in x (what we are taking logarithms of) must be equal. So we need to solve

4x - 10 = 3x + 9 => subtract 3x from both sides

4x-3x - 10 = 9 => add 10 to both sides

x = 9 + 10 = 19

Thank you,

MrB
