Find tan A ( write as a decimal rounded to the three decimal places) FIRST ANSWER GETS BRAINIEST

Answer:

19/8

Step-by-step explanation:

8x-7=-12

8x=19

x=19/8

Answer:

8-7n=-12

Step-by-step explanation:

Answer:

x ≈ 27.2

Step-by-step explanation:

Using the sine ratio in the right triangle

sin54° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{22}{x}[/tex] ( multiply both sides by x )

x × sin54° = 22 ( divide both sides by sin54° )

x = [tex]\frac{22}{sin54}[/tex] ≈ 27.2 ( to the nearest tenth )

Answer:

Terms: -8, -4c, 7, -c, -12c, -2

Variables: c

Coefficients: -4, -1, -12

Constants: -8, 7, -2

Step-by-step explanation:

Terms are anything in between a plus or minus.

Variables are anything that is not a real number, such as c.

Coefficients are the number directly before a variable, such as -4 in -4c.

Constants are any real numbers without a variable, such as -8.

Answer:

Step-by-step explanation:

Answer:

a = ±sqrt(3)

Step-by-step explanation:

a×a×a=a+a+a

Simplifying each side

a^3 = 3a

Divide each side by a

a^3 /a = 3a/a

a^2 = 3

Take the square root of each side

sqrt(a^2) = ±sqrt(3)

a = ±sqrt(3)

Answer:

nope its not equal

a×a×a=a³, but a+a+a=3a

so, a³≠3a

Answer: 300

Step-by-step explanation:

Answer: U = 18

Step-by-step explanation:

U in (-oo:+oo)

U/(-6)+2 = -1 // + 1

U/(-6)+1+2 = 0

3-1/6*U = 0 // - 3

-1/6*U = -3 // : -1/6

U = -3/(-1/6)

U = 18

U = 18

Answer:

-3 (-6u+6) - u = 2 (u-6) - 1​

18u -18 -u = 2u -12 -1

18u-u-2u=-12-1+18

15u= 5

u =5/15 = 1/3

Answer:

D. 2787.64 yd^3

Step-by-step explanation:

This is the formula for the volume of a cone:

[tex]V=\frac{1}{3} \pi r^2h[/tex]

The height of the cone is 22 yd. The radius of the base of the cone is not given but we can use the diameter to calculate it since the radius is equal to half of the diameter.

[tex]r=\frac{1}{2}d\\r=\frac{1}{2}(22)\\r=11yd[/tex]

Therefore, the radius of the base of the cone is 11 yd.

Now, we plug our values into the formula and solve.

[tex]V=\frac{1}{3} \pi r^2h\\V=\frac{1}{3} \pi (11^2)(22)\\V=\frac{1}{3} \pi (121)(22)\\V=\frac{1}{3} \pi (2662)\\V=\frac{1}{3} \pi (2662)\\V=2787.64 yd^3[/tex]

Therefore, the volume of the cone is equal to 2787.64 yd^3.

I hope this helps!

Answer:

Step-by-step explanation:

I don't know what you were supposed to do with 3 but 4 looks much easier.

It's telling you to increase the side lengths by a factor of 3y

4x(3y) + 4x(3y) = 3y * 3y

12xy + 12xy = 9y^2

Perimeter = 24xy + 9y^2

I can't see anything else to do with this question. If you think I've misread it or there is more to it, leave me a note.

Answer:

Concept: Numerical Analysis

Answer:

1/50 as far

Step-by-step explanation:

6.8 x 10[tex]^{16}[/tex] ÷ 3.4 x 10[tex]^{18}[/tex]

Rules state that you divide numbers and subtract exponents

6.8/3.4 = 2

10[tex]^{16}[/tex] ÷ 10[tex]^{18}[/tex] = [tex]10^{-2}[/tex]

whenever exponent is negative, it gets turned into a fraction with 1 as the numerator and the exponent will become positive when placed in the denominator

10^-2 = 1/10^2 which is the same as 1/100

2 multiplied by 1/100 = 1/50

Answer:

0.05nn + 0.10dd ≥ 2

*make sure it is either n or nn depending whether you had a typo in problem*

Step-by-step explanation:

First each nickel is worth 0.05

each dime is 0.10

and we must have a minimum so the total value has to be at least $2

so 0.05nn + 0.10dd ≥ 2

Answer:

54 km/h

Step-by-step explanation:

Step one:

given data

We are required to perform unit from m/s km/h

from 15m/s to km/h

Step two:

1 meter= 1/1000 km,

1 seconds= 1/3600 hour

1m/s = 1/1000/1/3600= km/h= 3600/1000= 36/10= 18/5 km/h

so of 1m/s is equivalent to 18/5 km/h

then 15m/s is equivalent to x

cross multiply

x= 15*18/5

x= 3*18

x=54 km/h

Answer:

y+2=-3(x+3)

Step-by-step explanation:

Your answer is D or $112 + 0.40($112)

Explanation:

I got it right on edge 2021

Answer:

E D C are the answers for the questions

Answer:

The answer is "The first choice"

Step-by-step explanation:

In the given question the first choice is correct because When the zero assumption was valid, it would have been at least as bad to also be 2% to demonstrate a discrepancy as observed difference.

The answer is 60 or 15 because you need to have 150 for a triangle

Answer: 36

Step-by-step explanation:

Sry I got 12 but I changed it since 36 is correct

Answer:

36

Step-by-step explanation:

( 3 * 2 ) ^(2)

Remember the order of operations;

1. Parenthesis

2. Exponents

3. Multiplication or Division

4. Addition or subtraction

( 3 * 2 ) ^ (2)

Simplify what is in parenthesis first.

(6)^(2)

Now simplify the exponent. Remember, the power or the degree to which the base is at is telling one the number of times one needs to multiply the base by itself;

36
