Answer:

The two bolts of 50.9 ft apart

Step-by-step explanation:

boat 1

$\tan(21) = \frac{45.33}{x} \\ x = \frac{45.33}{ \tan(21) } \\ x = 118.1 \: ft$

boat 2

$\tan(34) = \frac{45.33}{x} \\ x = \frac{45.33}{ \tan(34) } \\ x = 67.2 \: ft$

$118.1 - 67.2 = 50.9 \: ft$

PLEASE HELP ME IN MATH IM CONFUSED

Butoxors [25]

Answer:

the second choice is correct

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = $\frac{3}{4}$ x - 9 is in this form

with slope m = $\frac{3}{4}$

• Parallel lines have equal slopes, hence

y = $\frac{3}{4}$ x + c ← is the partial equation of the parallel line

To find c substitute (- 8, - 18) into the partial equation

- 18 = - 6 + c ⇒ c = - 18 + 6 = - 12

y = $\frac{3}{4}$ x - 12 ← equation of parallel line

Answer:

$V=210\ cm^3$

Step-by-step explanation:

The legs measuring 10 cm and 14 cm.

The height of the pyramid is 9 cm.

We need to find the volume of the pyramid. The formula for the volume of a right pyramid is given by :

$V=\dfrac{1}{3}Bh$

Where

B is area of base,

$B=\dfrac{1}{2}\times 10\times 14=70\ cm^2$

Put all the values,

$V=\dfrac{1}{3}\times 70\times 9\\\\V=210\ cm^3$

So, the volume of the right pyramid is equal to $210\ cm^3$ .
