Step-by-step explanation:

Answer:

∠A= 111.75°

Step-by-step explanation:

Please see the attached picture.

∠B +∠C= 180° (adj ∠s on a str. line)

(x +35)° +∠C= 180°

∠C= 180° -(x +35)°

∠C= 145° -x°

∠A= ∠C (corr. ∠s)

∠A= 145° -x°

Given that ∠A is (3x +12)°, equate this expression to the expression we found.

145° -x°= 3x° +12°

3x° +x°= 145° -12°

4x°= 133°

x°= 133° ÷4 (÷4 on both sides)

x°= 33.25°

Substitute the value of x back into the expression for ∠A:

∴∠A= 3(33.25°) +12°

∠A= 111.75°

Answer:

x=2

Answer: E

Step-by-step explanation:

You have to add 2 to the other side and shade to the left because it’s less than 18.

Answer:

Letter E

Step-by-step explanation:

To solve this, all you need to do is add two to both sides to isolate the x, and that will result in x ≤ 18. In a number line, it is a closed circle (because it has the line below the sign), and it points to the left because it is less than or equal to.

Step-by-step explanation:

Answer:

-3.5

Step-by-step explanation:

I got it correct.

Answer:

Brandon's methot is not correct

for example: x=9 9×1/2=4.5

Here's why:

Let's use his method to find the square root of 36. That means we multiply 36 by 1/2 = 0.5 to get 36*0.5 = 18; however, 18 is not the square root of 36. We can see that 18*18 = 324. Instead, the square root of 36 is 6 because 6*6 = 36.

As another example, let's say we want to find the square root of 64. With Brandon's method, we would get to 64*0.5 = 32, but 32*32 = 1024. Ashley's method is correct and 8*8 = 64 shows that 8 is the square root of 64.

As a visual approach, think of a square with side lengths 8 feet each. The area would be 8*8 = 64 square feet. If you didn't know the side length, but you knew that the area was 64 square feet, then you could apply the square root operation to find the side length to be 8 feet (or you could effectively use Ashley's guess-and-check method to arrive at 8 feet). In short, the square root operation is the opposite of squaring a number. We consider these inverse operations.

Multiplying by 1/2 is the same as dividing by 2. Division is the opposite of multiplication, and division is not the inverse of squaring a number. It's just a coincidence that Brandon's method happened to work on the value 4. But as shown earlier, it doesn't work in general.

Answer:

A)36

B)100

F)25

hope it helps.

Answer:

A = 36=6²

B = 100=10²

F = 25 =5²

those are the perfect square

The question is incomplete had the number of harvested apples isn't given.

Answer:

0.06n

Step-by-step explanation:

When a farmer harvests apples he expects 6% of the apples to be rotten how many apples would the farmer expect to be rotting when harvesting apples

The expected percentage of rotten apples when harvesting = 6%

The expected number of rotten apples can be obtained by taking the product of the expected percentage and the number of apples to be harvested.

Since the number of harvested apples isn't given,

Let the number of harvested apples = n

Therefore, the expected number of rotten apples will be :

6% * n

0.06n

Note : you can easily substitute the actual number of harvested apples for n in the equto get the actual answer

Answer: hello your question to the given scenerio is missing below is the missing question

question:  Does this setting represent a Binomial distribution ?

answer : Yes the setting represents a Binomial distribution

Step-by-step explanation:

The setting represents a Binomial distribution, because the criteria's for a Binomial distribution is all present which are

yes, this setting represent the binomial distribution.

Given that,

The student took 100 equal sized slips of paper and crinkled 25 of them before putting them all into a box.

After mixing well, they asked an uninformed person to select a winner at random.

We have to determine,

Does this setting represent a Binomial distribution.

According to the question,

Let Y = the number of times that a crinkled paper was selected.

The setting represents a Binomial distribution, because the criteria's for a Binomial distribution is all present .

These are the points which represents the given representation is a binomial distribution.

        [tex]Probability\ of \ success = \dfrac{25}{100} = 0.25[/tex]

Hence, yes this setting represent the binomial distribution.

Answer:

D. 60, 45,75

Step-by-step explanation:

For options C and D

For a triangle the sum of the angles must always be equal to 180 degrees

So 180 ≠45+45+80

and

60 +45+ 75= 180

For option A and B

The length of the longer side is equal to the square root of the sum of squares of the other two sides in a triangle.

According to Pythagorus theorem

hypotenuse²= base² + perpendicular²

c²= a²+ b²

90²= 50² + 35²

8100= 2500+1225

8100≠3725

95²= 60²+ 25²

9025= 3600+ 625

9025≠4225

Therefore only D is the correct option

When you see things that move at a non linear rate, it means that it is not a straight line. Automatically, you can eliminate A and D because the lines there between those numbers are straight.

Step-by-step explanation:

Answer:

The oil needed is 0.51.

Step-by-step explanation:

Since you know that the gas to oil ratio is 50:1 and you have to find the oil needed for 25.5L of gas, you can write the numbers in the ratio as a fraction and let's consider that x is the amount of oil needed:

[tex]\frac{50}{1} = \frac{25.5}{x}[/tex]

Now, you have to solve this using cross multiplication:

50*x=25.5*1

50x=25.5

Finally, your have to isolate the variable x:

x=25.5/50

x=0.51

According to this, the answer is that the oil needed is 0.51.
