Alex17521 [72]

The question was posted incomplete.

This is the part missing:

<span>What is the height of the plane to the nearest meter?

Answer: 559 m.

Explanation:

1) The horizontal distance between the plane and tha atoll makes a right triangle with the height, with the depression angle between the two legs.

2) Therefore, you can use the tangent trigonometric ratio:

tan(10°) = opposite-leg / adyacent-leg = height / horizontal distance

⇒ height = horizontal distance × tan (10°)

⇒ height = 3,172 m × tan(10°) = 559.31 m, which rounded to the nearest m is 559

The formula for the area of a trapezoid with altitude k and bases m and n is . A=k/2 (m+n) solve for m..

SashulF [63]

Answer:

$m=A\times\frac{2}{k}-n$

Step-by-step explanation:

Given : The formula for the area of a trapezoid with altitude k and bases m and n is $A=\frac{k}{2}(m+n)$

We have solve for m .

Consider the given formula $A=\frac{k}{2}(m+n)$

Multiply both side by $\frac{2}{k}$ , we have,

$A\times\frac{2}{k}=m+n$

Now subtract n both side, we have,

$A\times\frac{2}{k}-n=m$

Thus, $m=A\times\frac{2}{k}-n$

Arbara signed up for dance lessons at Dance Unlimited. She was charged $55 per month for lessons and a one-time recital fee of $

kramer

Given:

Per month fee = $55

One-time recital fee = $165

The equation represents the $495 total cost that Barbara paid to Dance Unlimited.

$495=165+55m$

To find:

We need to find the number of month Barbara receive dance lessons from Dance Unlimited.

Solution:

We have,

$495=165+55m$

Here, m is number of months. We need to isolate m.

Subtract 165 from both sides.

$495-165=55m$

$330=55m$

Divide both sides by 55.

$\dfrac{330}{55}=m$

$6=m$

The value of m is 6. So, the required number of month Barbara receive dance lessons from Dance Unlimited is 6.

Maya has 5 over 6 cup of ice cream. How many 1 over 4-cup servings are in 5 over 6 cup of ice cream? ASAP I need help

Ierofanga [76]

Answer:

Find the LCD (least common denominator)

{5}/{6} and {1}/{4}

it would be 12 (6x2=12 and 4x3=12)

so you multiply {5}/{6} by 2 and get {10}/{12}

then multiply {1}/{4} by 3 and get {3}/{12}

you get 3 WHOLE servings from {5}/{6} cups of icecream
