perpendicular to the base of the building. Now suppose that she measures the angle of depression from the
top of the building to the closest point to be 35.5º and the angle of depression from the top of the
building to the furthest point to be 29.3º. Determine the height of the building. (Round your answer to the

Simplify: 3[(7 - 5) 2 + (20 - 19) 2] + 14

Answers

Answer:

32

Step-by-step explanation:

We first solve everything in the parenthesis. So: (7 -5) = 2 and (20 - 19) = 1. Now we change the equation:

3[(2)2 +(1)2] + 14

Then we multiply inside the brackets: 2 x 2 = 4 and 1 x 2 = 2. So the equation now looks like this:

3[ 4 + 2] + 14

Now we add:

3{6} + 14:

We multiply:

18 + 14

Finaly we add again:

18 + 14 = 32

What percentage of 3hrs is 45 mins​

Answers

Answer:

25%

Step-by-step explanation:

First convert 3 hours into minutes by multiplying 3 x 60 min/hr. This is 180 minutes. To find the percentage, divide 45 minutes by 180 minutes and then multiply by 100.

45/180=0.25x100 = 25%

The time 45 minutes is 75 percentage of 3 hours

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the percentage be represented as A

Now , the equation will be

The time be represented as p = 45 minutes

The value of p = 3/4 hours

The value of q = 3 hours

So , the percentage is A = ( p/q ) x 100

Substituting the values in the equation , we get

The percentage A = ( 3/4 ) / 3 x 100

On simplifying the equation , we get

The percentage A = ( 3/12 ) x 100

The percentage A = ( 1/4 ) x 100

The percentage A = 25 %

Hence , the percentage is 25 %

The angle of elevation to a nearby tree from a point on the ground is measured to be 66^{\circ} ∘ . How tall is the tree if the point on the ground is 68 feet from the tree? Round your answer to the nearest tenth of a foot if necessary.

Answers

By comparing with a right triangle, we will see that the height of the tree is 62.12ft

How tall is the tree?

We can compare the situation with a right triangle. Such that the hypotenuse measures 68 ft, and an angle measures 66°.

We want to get the height of the tree, which would be the opposite cathetus, then we can use the relation:

Sin(a) = (opposite cathetus)/hypotenuse.

Sin(66°) = H/68ft

Tan(66°)*68ft = H = 62.12ft

The height of the tree is 62.12ft

you have to substitute the equation. sub y=1x-1 into the other equation.

Answers

Answer:

-y = x-1 is a fairly simple equation at least with real integers.

I hope to help you understand the process of solving it so you can apply the thinking to increasingly difficult equations. If this equation is difficult for you, I will try to explain it simply.

let's try a simple trick. If you want to solve for y, then it's helpful to remove the negative from it.

that means you need to do the same thing to the x side, but since x is already positive it needs to change to -x to balance things out.

the equation now reads y = -x+1 because we have reversed the negative and positive values on both sides of the equation.

I hope this helps simplify the thinking behind solving an equation of this nature. The two previous answers above this one are both correct, but may be just a tad more complex than you need at this moment.

-4+x=10 is 13 the solution

Answers

Answer:

No.

Step-by-step explanation:

You are trying to solve for x. Note the equal sign, what you do to one side, you do to the other. Add 4 to both sides of the equation to isolate the variable, x:

-4 + x = 10

-4 (+4) + x = 10 (+4)

x = 10 +4

x = 14

x = 14, x ≠ 13, ∴ 13 is not a solution.

~

No 13 is not the solution. Add 4 to both sides to get x by itself.
So x minus 4 plus 4 equals
X
And
10 plus 4 equals 14
So x equals 14 not 13
