How are angle 4 and angle 5 related?

Answer is -9

5(x-2)-3x=6x+26

or,5x-10-3x=6x+26

or,5x-3x-10=6x+26

or,2x-10=6x+26

or,2x-6x=26+10

or,-4x=36

or,x=36/-4

or,x=-9 proved

Answer:

True!

Step-by-step explanation:

If an object travels at a constant speed, then the distance traveled is directly proportional to the time spent traveling, with the speed being the constant of proportionality. The circumference of a circle is directly proportional to its diameter, with the constant of proportionality equal to π.

Answer:

(3x^2+6x)/(x^2-16)

Step-by-step explanation:

When multiplying fractions you just go straight accross

this means that our fraction is equal to

((x+2)(3x))/((x-4)(x+4))

The numerator is quite easy 3x(x+2)=3x^2+6x

The second one is a little tough at first and if you need help I would reccomend using khan academy

but pretty much you get x^2-16

put them together and get your answer

Answer:

5^12

Step-by-step explanation:

When you have a power to the power, you multiply the powers. Since we have (5^3)^4, we can multiply the powers because we have a power to the power. Since 3 * 4 is equal to 12, we have 5^12. That means that 5^12 is the answer.

Answer:

16π cm²

Step-by-step explanation:

circumference = 2πr

Area = πr²

We need to determine r to calculate the area

2πr = 8π

Divide both sides of the equation by 2π to find r

r = 4

Now, we determine area.

area =  πr² =   π4² = 16πcm²

Answer:

Step-by-step explanation:

The formula for the circumference of a circle can be used to solve this problem.

[tex]\underline{\text{CIRCLE OF A CIRCUMFERENCE FORMULA:}}[/tex]

[tex]:\Longrightarrow: \sf{C=2\pi r}[/tex]

[tex]\text{AREA:}= \sf{\pi r^2}[/tex]

[tex]\sf{2\pi r=8 \pi}[/tex]

You have to divide by 2 from both sides.

[tex]\sf{\dfrac{2\pi r }{2}=\dfrac{8\pi}{2} }[/tex]

Solve.

Divde the numbers from left to right.

8/2=4

r=4

[tex]\sf{\pi r^2=\pi4^2}[/tex]

Solve by exponents.

[tex]\sf{4^2=4*4=\boxed{\sf{16}}[/tex]

[tex]\Longrightarrow: \boxed{\sf{16\pi \text{cm}^2}}[/tex]

Answer:

  80.5°

Step-by-step explanation:

The applicable trig function is the tangent.

  Tan = Opposite/Adjacent

In this scenario, the side opposite the angle is the tower height, 324 m. The side adjacent is the distance to the tower, 54 m. Then the angle α is related by ...

  tan(α) = 324/54

The value of the angle with this tangent is found using the arctangent function:

  α = arctan(324/54) ≈ 80.5°

She should set her binoculars to 80.5°.

Answer:

A=1

Step-by-step explanation:

Because A would stand for a variable and a variable would equal to 1

Answer:

The first thing to do when solving an algebraic equation is the isolate the variable.  Thus, simply subtract 1/2x from both sides of the equation and subtract 5 from both sides to get [tex]-2=\frac{1}{2} x[/tex]

Answer:

Tom's share = €800

Step-by-step explanation:

Given that:

Amount shared by Al, Tom and Joe = €3000

Ratio of Al's share to Tom's share = 5 : 4

Joe's share = 1.5(Tom's share) = 1.5(4) = 6

Therefore,

Ratio of Al, Tom and Joe = 5 : 4 : 6

Let,

x be the number of times of amount each get.

5x + 4x + 6x = 3000

15x = 3000

Dividing both sides by 15

[tex]\frac{15x}{15}=\frac{3000}{15}\\x=200[/tex]

Tom's share = 4x = 4(200) = €800

Hence,

Tom's share = €800

Answer:

Jackson is 12 and Shelly is 6.

Step-by-step explanation:

Since we know Jackson is two times older than Shelly, it only makes since for our answer to be 12.

to find this you can make two circles and add dashes in each until you reach 18, but add 2 to Jackson to each 1 you put for Shelly.

Answer:

Her percent error was: ≈ 17% (whole percent)

Step-by-step explanation:

Given

Approximate value = 20 friends

Exact Value = 24 friends

To determine

Percent error

Using the formula to calculate the Percent error

Percent error = | Approximate Value| - Exact Value | / | Exact value | × 100

                       = | 20 - 24 | / | 24 | × 100

                       = | - 4 | / | 24 | × 100

Apply absolute value: |-a| = a,   a>0

                       = 4/24 × 100

                       = 16.67 %

                       ≈ 17% (whole percent)

Thus, her percent error was: ≈ 17% (whole percent)
