Answer:

length = 11.4 mi

Step-by-step explanation:

Area of triangle = 1/2 * height * length - Now, lets substitute

41.6 = 1/2 * 7.3 * length - Now, lets solve the equation!

length = 11.3972602739726 - round it up to the nearest tenth

length = 11.4 mi

Hope this Helps)))

Answer:

11.4 mi

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = $\frac{1}{2}$ bh ( b is the base and h the height )

Here A = 41.6 and h = 7.3 , b is to be found, thus

$\frac{1}{2}$ × 7.3b = 41.6, that is

3.65b = 41.6 ( divide both sides by 3.65 )

b ≈ 11.4 ( to the nearest tenth )

Marta is solving the equation s=2πrh+2πr^2 for h. which should be the result?

Marta_Voda [28]

Answer: First option.

Step-by-step explanation:

Marta needs to subtract $2\pi r^2$ from both sides of the equation:

$s=2\pi rh+2\pi r^2$

$s- 2\pi r^2=2\pi rh+2\pi r^2- 2\pi r^2$

$s- 2\pi r^2=2\pi rh$

Now she needs to divide both sides of the equation by $2\pi r$ , then:

$h=\frac{s- 2\pi r^2}{2\pi r}$

Rewriting:

$h=\frac{s}{2\pi r}-\frac{2\pi r^2}{2\pi r}$

Simplifying, she should get:

$h=\frac{s}{2\pi r}-r$

This matches with the first option.

Estimate each product. 2/3×26

kondor19780726 [428]

If i understand the question.
you are estimating up each number.
so it would be 2/3 going into 1 and 26 going into 30
both turning into whole numbers.

Task 3:

Natalija [7]

Answer:

A. 4.5 ft

B. 4 ft

C. 1 ft

Step-by-step explanation:

If you pretend that h is replacing y and d is replacing x and you would graph the equation, then you would get a parabola that opens down.

You would need to find the vertex of the parabola. The ordered pairs would be (d, h) instead of the normal (x, y).

A. The maximum height will be the h value of the vertex

B. Let h = 0 and solve the equation for d. That will give you distance from the stump that the frog landed.

C. The distance from the log at the maximum height is the d value of the vertex

So, that is what is needed to be done.

Without me going thru all the work, the vertex is (1, 4.5) and the solutions to the equation when h = 0 are 4, -2 (discard -2 since a distance cannot be negative)

So the answer to A is 4.5 ft.

The answer to B is 4ft.

The answer to C is 1 ft.

Now, can you find the vertex on your own and can you solve the equation when h = 0? I hope so. OK?
