Solve using pemdas 3 plus 7 times 6 divided by 3

kondor19780726 [428]

Answer:

Step-by-step explanation:

3 + 7 * 6 / 3

PEMDAS says we multiply and add before adding and subtracting so we multiply first (going from left to right)

3 + 42 / 3

Then we divide

3 + 14 = 17

A new television set was recently purchased for a common room in a residence hall for $408.00 including tax. If the tax rate is

Nadusha1986 [10]

Answer:

$400

Step-by-step explanation:

To solve this, we need to understand how one reaches the final price. The general formula for final price (with tax) is:

t(c) = p x (1+t)

t(c) is total cost

p is price

t is tax rate as a decimal

To find p, we need to create a new formula. Since we have the total cost ($408) and the tax rate (2% or .02), we can divide the total cost by 1 + the tax rate to solve for the price:

t(c) / (1+t) = p

408 / (1+.02) = $400

I hope this helps!

Aiko stands 5 m from a tree. At that distance, the angle of elevation from the ground to the top of the tree is 80°.

denis23 [38]

Answer:

$\boxed {\boxed {\sf About \ 28.36 \ meters }}$

Step-by-step explanation:

Assuming the tree is perpendicular to the ground, we can use the right triangle trigonometric ratios to find the tree's height.

sin(θ)= opposite/hypotenuse
cos(θ)= adjacent/hypotenuse
tan(θ)= opposite/adjacent

Now, let's draw a diagram. We know Aiko is 5 meters from the base of the tree. From there, the angle to the top of the tree is 80 degrees. We are looking for x, the tree's height. The diagram attached is not to scale.

We base the sides off of the angle. x is opposite of 80 degrees and 5 is adjacent. Therefore we must use tangent.

$tan(\Theta)=\frac{opposite}{adjacent}$
