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:

To find the circumference of a cylinder, you have to be aware that a cylinder's cross-section is a circle. If you know the cylinder's radius: Multiply the radius by 2 to get the diameter. Multiply the result by π, or 3.14 for an estimation. That's it; you found the circumference of the cylinder.

1. Subtraction property

2. Division property

Step-by-step explanation:

Question has missing details.

Kira's steps are:

[tex]\frac{7}{2} - 2x = \frac{11}{2}[/tex]

[tex]\frac{7}{2}- \frac{7}{2} - 2x = \frac{11}{2}- \frac{7}{2}[/tex]

[tex]- 2x \div -2= \frac{4}{2} \div -2[/tex]

[tex]x = -1[/tex]

Required

The properties used

For the first step, we have:

[tex]\frac{7}{2} - 2x = \frac{11}{2}[/tex]

To get to step 2, Kira subtracted [tex]\frac{7}{2}[/tex] from both sides.

i.e.

[tex]\frac{7}{2}- \frac{7}{2} - 2x = \frac{11}{2}- \frac{7}{2}[/tex]

This property is subtraction property

In the second step, where x is isolated.

[tex]- 2x \div -2= \frac{4}{2} \div -2[/tex]

Both sides of the equation were divided by -2  to give:

[tex]x = -1[/tex]

This property is division property

Answer:

person above correct

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

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:

  16π/17 radians ≈ 169.41°

Step-by-step explanation:

The arc length of the sector is the circumference of the cone:

  C = 2πr = 2π(4 cm) = 8π cm

The angle and arc length are related by ...

  s = rθ . . . . . θ in radians

  8π cm = (8.5 cm)θ

  θ = 8π/8.5 = 16π/17 . . . . radians

bii) The angle of the sector is 16π/17 radians ≈ 169.41°.

Answer:

169° (3sf)

Step-by-step explanation:

the area of a circle multiplied by the angle over 360 gives you ans.

x/360 × π × r²=34π -> ur ans frm part i

x × π(8.5²)=12240π

x × 72.25=12240

x=169.41°

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.

Step-by-step explanation:

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. Now we have two non linear lines left and there is only one that is decreasing (going down and it is the line between -2 and 0.

Answer:

(x+4)x

Step-by-step explanation:

The factor of the expression into an equivalent form x² + 4x would be;  x(x + 4)

Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.

To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.

We need to factor the expression into an equivalent form x² + 4x

This expression could also be given by;

x² + 4x

Then factor out x we get;

x² + 4x =  x(x + 4)

Hence, the expression into an equivalent form x² + 4x would be; x(x + 4)

Answer:

x = 5

Step-by-step explanation:

Because the red-marked lines are parallel, we know that the ratios are the same

5x : 45 = 20 : 36

5x/45 = 20/36

5x * 36 = 20 * 45

5x * 4 = 20 * 5

5x * 1 = 5 * 5

x = 5
