Answer:

m∠2 = 104°

m∠3 = 76°

m∠4 =  104°

Step-by-step explanation:

∠1 and ∠3 are vertical angles

That means they are of the same value.

∠2 and∠4 are also vertical angles and we can find the value like this:

Sum of all angles = 360°

Total value of found angles = 152°

Number of angles need to be found = 2x (note: this is 2x because both angles are the same)

Equation = 360 - 152 = 2x

208 = 2x

x = 208/2

x = 104

So angle m∠4 = 104°

and m∠2 = 104°

Answer:

a. 80 units

b. 482.843 units²

Step-by-step explanation:

First things first, we need to solve for the side of the octagon. We can do so by using Pythagorean Theorem: a² + b² = c² where c is the hypotenuse and a and b are the other two sides.

12² + b² = 13²

144 + b² = 169

b² = 25

b = 5

Now that we know half of the side of the octagon is 5, we know that one side of the octagon is 10.

a. To find perimeter we just add every side together (or since every side is the same size, we multiply by 8)

10 × 8 = 80

b. The formula for finding the area of an octagon is 2(1 + radical 2)a² where a is the length of a side. By plugging in to a calculator we get:

2(1 + radical 2)(10)² = 482.843

Please mark me as brainliest. thanks!!!

Answer:

Option (B)

Step-by-step explanation:

Let the weight of one container = x pounds

Therefore, weight of 5 containers = 5x pounds

Weight of the platform = 30 pounds

Total weight of the platform and containers = (5x + 30) pounds

If the maximum weight that can be lifted by the cable = 780 pounds

Inequality representing this situation will be,

(5x + 30) < 780

5x < 780 - 30

5x < 750

x < 150

Therefore, Option (B) is the answer.

Pythagorean Theorem

•a²+4²=4.5²

•a²+16=20.25

•Subtract 16 from both sides

•a²=4.25

•Remove the square root

•√a²=√4.25

•a=2.06155

Answer:

Step-by-step explanation:

In math, when a number is squared, it means it has been multiplied by itself. For instance, two squared equals two times two, or four.

In this same case x^2---> x * x

x times x ---> x^2

Answer:

[tex]x=10[/tex]

Step-by-step explanation:

Pythagorean theorem: [tex]a^{2}+b^{2}=c^{2}[/tex]

Answer:

B

Step-by-step explanation:

Pythagorean theorem states that a²+b²=c²

Through observation, I assumed that 8 was the hypotenuse

I sqaured both the known lengths of the leg and hypotenuse and plugged them into the equation: a²+36=64

I subtracted 36 from 64 leaving me with 28=a²

Then in order to isolate the variable I had to apply square root to both values, cancelling the "²" and leaving me with √28=a

Answer:

8

Step-by-step explanation:

If you add the ratios together, it is equal to 9

Since NQ = 9, 9/9=1

So each unit is 1

Then you can just add 5*1 + 3*1

Which is 8

Answer:

A food distribution company has employees that order food supplies for local restaurants by predicting sales. It is important that the employees order the correct amount of food. If they order too much, the food will spoil. If they don’t order enough, the restaurant will not get the food they need. The company pulls an SRS of 500 orders and finds that 408 of the orders were correct. Calculate and interpret a 95% confidence interval for the proportion of all orders that were correct.(4-step process)

Answer:

#. x=12.75

Step-by-step explanation:

51/4

10% off means she pays 90% of the original price. (100% - 10% = 90%)

62 x 0.90 = 55.80 the sale price of the dress is $55.80

Now add the tax by multiplying the sale price by 1 + tax rate:

55.80 x 1.0675 = 59.57

She paid $59.57

Answer:

10% off means she pays 90% of the original price. (100% - 10% = 90%)

62 x 0.90 = 55.80 the sale price of the dress is $55.80

Now add the tax by multiplying the sale price by 1 + tax rate:

55.80 x 1.0675 = 59.57

She paid $59.57

Answer:

27°

Step-by-step explanation:

I'm assuming you have learned basic trigonometry: SOH CAH TOA. In this diagram to find the angle x we are given the opposite side and the hypotenuse, therefore we will use SOH. sinθ = opp/hyp. Plugging in those values we get sinθ = 5/11 -> θ = sin⁻¹ (5/11) = 27.03569179° = 27°

Answer:

(2,2)

Step-by-step explanation:

Step-by-step explanation:

So looking at this question, we have two variables (1 - a glass of milk; 2 - a snack bar) and two equations to use to solve for the two variables. Remember that for any number of variables, you need that same number or more equations to solve for the variables.

Let's say that a glass of milk is represented by g and a snack bar is represented by s.

So we essentially have two equations here:

4 glasses of milk + 3 snack bars = 88 carbs, or:

4g + 3s = 88

2 glasses of milk + 4 snack bars = 74 carbs, or:

2g + 4s = 74

Now that we have this, we can solve for our equations. There are two ways to do this:

SUBSTITUTION - solve for one variable, then substitute it in

Let's solve for g using the second equation. First, we'll isolate g by subtracting 4s from both sides.

2g = 74 - 4s

Next, we can divide the whole equation by 2 to solve for g.

g = 37 - 2s

Now, we can substitute this into the first equation for g and solve for s.

4g + 3s = 88

4(37 - 2s) + 3s = 88

148 - 8s + 3s = 88

148 - 5s = 88 (now subtract 88 from both sides and add 5s to both sides)

60 = 5s

s = 12

Now we can use this to solve for g in the original equation

g = 37 - 2s

g = 37 - 2(12) = 37 - 24 = 13

ELIMINATION - eliminate one variable to solve for the other, then use that to solve for the first

Let's look at our two equations

4g + 3s = 88

2g + 4s = 74

Let's eliminate the variable g first by multiplying the second question by -2.

4g + 3s = 88

-4g - 8s = -148

If we add these two equations together, we get

-5s = -60

Divide both sides by -5 and we get

s = 12

Now, we can plug s into either equation to solve for g as we did above.
