Answer:

d = 6.1m

n = 7km

Step-by-step explanation:

To find the variables, use tan

⇒ tan = \frac{opposite}{adjacent}

finding d:

⇒tan 63 = \frac{d}{3.1}

tan of 63 is 1.963

⇒ 1.963 = \frac{d}{3.1}

multiply 3.1 on both sides

⇒ 1.963 x 3.1 = \frac{d}{3.1} x 3.1

⇒ 6.0853 = d

round to the nearest tenth:

⇒ 6.0853 = 6.1

finding n:

⇒ tan 45 = \frac{7}{n}

tan of 45 is 1

⇒ 1 = \frac{7}{n}

multiply 7 on both sides:

⇒ 1 x 7 = \frac{7}{n} x 7

7 = n

Answer:

D = 1.4, N =

Step-by-step explanation:

<em>To get D you need to find the cosine of 63 degrees </em>

<em>Cosine(63) = D / 3.1</em>

<em>Multiply by 3.1 to isolate D :</em>

<em>3.1Cosine(63) = D</em>

<em>Put it into a calculator and you'll get 1.4.</em>

Also, it's a 45-45-90 triangle so the 2 legs will be equal to each other.

Proof: To get N put you have to do the tangent of 45 degrees

Tan(45) = 7 / N

Now you can't to do this you have to multiply the both sides by N

N(tan(45)) = 7

Then divide both sides by (tan(45))

N = 7 / (tan(45)

Put it into the calculator and you'll get

Use the distributive property to remove the parentheses. -6(11 - 2)​
salantis [7]

Answer:

-66+12 or -54

Step-by-step explanation:

To remove the parenthesis multiply the number outside of the parenthesis (in this case -6) to the numbers inside of the parenthesis (11, and -2).

-6*11=-66

A negative multiplied by a positive is a negative.

-6*-2=12

A negative multiplied by a negative is a positive.

-66+12=-54

How do I use the subtraction theorem to write equivalent expressions?
Andreas93 [3]
The subtraction theorem states that for all real numbers, a and b, a-b=a+(-b).
(To subtract, we can add the inverse.)
Thus, we can have the these two equivalent expressions.

3 - 2 = 3 + (-2) = 1\\ \\ 5 - (-2) = 5 + 2 = 7

The lead statue of the Korean War Memorial in Washington DC casts a 43.5 inch shadow at the same time a nearby tourist casts a 3
AfilCa [17]

Answer:

The lead statue is 87 inches tall

Step-by-step explanation:

Let

x ----> the height of the lead statue

using proportion

we know that

The height of the  lead statue divided by the length of his shadow must be equal to the height of the tourist divided by the length of his shadow.

so

\frac{x}{43.5}=\frac{64}{32}\\\\\frac{x}{43.5}=2\\\\x=2(43.5)\\\\x=87\ in

Use your equation from Exercise 6 to find m when n=40
Andreyy89

Answer:

=4/5(N+7)N

Step-by-Step Explanation:

We move all terms to the left:

-(4/5(N+7)N)=0

Domain of the equation: 5(N+7)N)!=0

N∈R

We multiply all the terms by the denominator

-(4=0

We add all the numbers together, and all the variables

=0

N=0/1

N=0
