Answer:

x = 7.4

Step-by-step explanation:

cos(42°) = x/10 or distance from bases / rope length

Using the calculator find the value of cos(42°):

cos(42°) = 0.74 = x/10

Find x using the value of cos(42°):

x/10 = 0.74

x = 7.4

Answer:

[tex]2(x+2)/x+1[/tex]

Step-by-step explanation:

Answer:

2( x +2 )

x+1

Step-by-step explanation:

to add or subtract expressions expand them to make their denominators the same, multiply 1 time [tex]\frac{x-2}{x-2}[/tex]

since [tex]\frac{x}{x-2}[/tex] and [tex]\frac{x-2}{x-2}[/tex] have the same denominators add them by adding their numerators

combine x + x -2

factor [tex]x^{2}[/tex] - 4

to add or subtract expressions expand them and multiply by 1

have same denominator add them by adding their numerators

do the multiplications in 3 + ( x-2 )(x+2)

combine like terms in 3 + [tex]x^{2}[/tex] + 2x - 2x -4

divide [tex]\frac{2x-2}{x-2}[/tex] by [tex]\frac{-1 + x^{2} }{(x-2)(x+2) }[/tex] multiplying [tex]\frac{2x-2}{x-2}[/tex]

cancel out x-2 in both numerator and denominator

factor the expression that are not already factored

cancel out x-1  in both numerator and denominator

expand the expression

Answer:

To solve for n, working backwards can help a lot.

Step-by-step explanation:

The last step we took to result in 40 was to add 12. Therefore, working backward would acquit us to subtract 12.

40 - 12 = 28

After we have done that, we need to observe the first step that we took. This was to double n. Similar, to the last order of operations we took in the previous step, we need to perform the opposite of doubling a number. Because the number is being doubled, it is being multiplied by itself. For example, if we double 4, we would receive 8. Likewise, 4² is 8. So, what is the opposite of multiplication? Well, it's division of course!

28 ÷ 2 is 14.

Therefore, n is 14.

The answer is A

Answer:

log (2/5)

Step-by-step explanation:

The rule/law you have in mind is as follows:  log a - log b = log (a/b).

Thus, your log 2 - log 5 = log (2/5).

Answer:

Step-by-step explanation:

First Question: Equilateral triangles all have the same interior angles. 60 degrees. Size does not make the angles bigger. It makes the sides bigger.

Second Question: No the size does not influence the size of the interior angle.

Third Question: That's true for all polygons. Size is not affect the interior angle size.

x=3

Hi! Your answer is x = 3.

Please see an explanation for a clear and better understanding to your problem.

Any questions about my answer and explanation can be asked through comments! :)

Step-by-step explanation:

Our goal is to find the value of x. That means what we have to do is to isolate x-term first.

[tex]\huge{x+10=13}[/tex]

To isolate a variable means that to make a variable as a subject or also known as leaving a variable alone. To isolate the x-term for this problem, simply subtract both sides by 10 so we can get rid of 10 from the left side.

[tex]\huge{x+10-10=13-10}\\\huge{x+0=3}\\\huge{x=3}[/tex]

If you are not sure that the answer is correct or not. We can substitute the value of x in the equation.

[tex]\huge{x+10=13}[/tex]

Substitute x = 3 in the equation.

[tex]\huge{3+10=13}\\\huge{13=13}[/tex]

The equation is true for x = 3. Hence, we can conclude that x = 3 is the solution to the equation.

Answer:

Step-by-step explanation:

A certain number of nickels, dimes and quarters have a value of $5.60 there are an equal number of each type of coin. How much coins are there?

(0.05+0.10+0.25)c =5.60

0.40c=5.60

40c=560

c = 14

There are 14 nickels ,dimes and quarters.

Answer:

Step-by-step explanation:

perimeter=2(125+80)=2(205)=410 yards

let the length of new rectangle be x and y.

Perimeter=2(x+y)

2(x+y)=410

x+y=410/2=205 yards

y=205-x

area A=xy=x(205-x)=205x-x²

[tex]\frac{dA}{dx} =205-2x\\\frac{dA}{dx}=0,gives~205-2x=0\\x=\frac{205}{2}\\\frac{d^2A}{dx^2}=-2<0 ~at~x=\frac{205}{2}\\[/tex]

A is maximum at x=205/2

y=205-205/2=(410-205)/2=205/2

so x=205/2=102.5 yards

y=205/2=102.5 yards

Answer: I don't know how to do the first question but I think I did the 2nd question correctly I believe we learned this in 7th grade.  I am a freshman so if it is wrong I am sorry anyways the answers for #2 are

B: 15 for MN

and C: 30 for JL

Perimeter: is 79.  

This was fun to do lol ik it wasn't much but better than nothing.  

Step-by-step explanation:

11.7

Formula: a^2 + b^2 = c^2

so substitute the numbers like this:

10^2 + 6^2 = c^2

both 10^2 and 6^2 are perfect squares:

10 × 10= 100 and 6 × 6= 36

100 + 36= c^2

add:

100 + 36 =

136 = c^2

now in order to get rid of the squared, you put it into a radical:

√136 = √c^2

note: whatever you do on one side, you do to the other

it's easier to use the calculator for this so put √136 and you're gonna get 11.66

since it's asking you to round it to the nearest tenth:

11.66 = 11.7

sorry if the explanation is kinda long ✋ i tried explaining it better in the end but i failed

Step-by-step explanation:

G(x) = 2/3 x - 6     switch x and y around and solve for y.

y = 2/3 x - 6

x = 2/3 y - 6

x + 6 = 2/3 y

3/2  x + 9 = y

Answer:

Step-by-step explanation:

Your answer

About all the sides are equal so we can say (10x + 44) side's triagle is twice than another triangle

So, 10x + 44 = 2( 8x - 23)

..... 10x +44 = 16x -46

...... X = 15
