Answer:

x = 45°

Step-by-step explanation:

the triangle has 2 congruent sides and is therefore isosceles with the base angles being congruent, both x

the sum of the 3 angles = 180° , then

x + x + 90° = 180° ( subtract 90° from both sides )

2x = 90° ( divide both sides by 2 )

x = 45°

Answer:

12

Step-by-step explanation:

it will be 12 because if you see the length were number 12 is it's the same as the other side

Answer:

∠ 2 = 40°

Step-by-step explanation:

∠ 1 and ∠ 2 are corresponding angles and congruent, thus

∠ 2 = ∠ 1 = 40°

The 3 angles when added together need to equal 170.

To find the 3rd angle subtract the 2 given angles from 180

180-30-70 = 80

Answer: B. 80

Answer:

B) 80

Step-by-step explanation:

All triangles add up to 180 degrees

So to solve angle 3 the equation would be

Angle 3 = 180 - Angle 1 - Angle 2

Angle 3 = 180 - 30 - 70

Angle 3 = 80

Answer:

B 452.16 cm^3

Step-by-step explanation:

the volume of the cylinder is 16π x 9, and if we replace π with 3.14, the answer will be 452.16 cm^3

Step-by-step explanation:

[tex]v = \pi \: r {}^{2} h[/tex]

v = ?

r = 4 cm

h = 9 cm

[tex]v = \frac{22}{7} \times 4 {}^{2} \times 9[/tex]

[tex]v = \frac{22}{7} \times 16 \times 9[/tex]

[tex]v = \frac{3168}{7} [/tex]

[tex]v = 452.57 \: cm {}^{3} [/tex]

Using the relation between velocity, distance and time, it is found that the trip took 2 hours.

Velocity is distance divided by time, that is:

[tex]v = \frac{d}{t}[/tex]

On the first part of the trip, a time of t was taken, with an average speed of 60 km/hour, hence:

[tex]60 = \frac{d}{t}[/tex]

d = 60t

On the second part, a time of t + 1 was taken, with an average speed of 40 km/hour, hence:

[tex]40 = \frac{d}{t+1}[/tex]

d = 40(t + 1).

Since the distance is equal for both parts, we can equal the equations and find the time.

60t = 40t + 40

20t = 40

t = 2.

The trip took 2 hours.

Step-by-step explanation:

Paxton multiplied 2/3 times the 5 in the numerator. Then he multiplied the 3 and 8 in the denominator.

The correct way to solve this problem would be to multiply the numerators and then multiply the denominators. This would give you 10/24. You can then divide the numerator and deonminator by 2 and get 5/12.

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

A function is a fifth-degree polynomial.

Now,

Since, We know that;

The turning point of n degree polynomial = n - 1

Here, The highest power of the polynomial = 5

Thus, The turning point of 5 degree polynomial = 5 - 1

                                                                           = 4

Therefore, A function with a fifth-degree polynomial have 4 turning points.

Answer:

280 inches

Step-by-step explanation:

The area can be found by looking at each shape individually.

The area of the square can be found my multiplying the length by the width...
14*14 = 196 square inches

The area of the triangle can be found by multiplying the base by the height and dividing by 2...
A = b*h/2 (or some text books say half of the base times the height)

We knot the height of the triangle is 12 inches, and the base is implied as it shares a side with a square which has 4 equal sides of 14 inches.  Therefore
A = (14*12)/2 = 84 square inches

We get the total area by combining the two segments...
Area (triangle) + Area (square) = Area (total)
84 + 196 = 280 square inches

Answer:

a = 17

Step-by-step explanation:

using the cosine ratio in the right triangle and the exact value

cos45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then

cos45° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{a}{17\sqrt{2} }[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )

a × [tex]\sqrt{2}[/tex] = 17[tex]\sqrt{2}[/tex] ( divide both sides by [tex]\sqrt{2}[/tex] )

a = 17

b = 17 since the legs of an isosceles triangle are congruent

Using the normal distribution, it is found that:

1. 85% of NBA players are taller than Greg.

2. 15% are shorter.

3. A height of 6'11'' would be needed.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem:

Item 1:

The proportion is one subtracted by the p-value of Z, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{75 - 79}{3.9}[/tex]

[tex]Z = -1.03[/tex]

[tex]Z = -1.03[/tex] has a p-value of 0.15

1 - 0.15 = 0.85.

85% of NBA players are taller than Greg.

Item 2:

100 - 85 = 15% are shorter.

Item 3:

This is X when Z has a p-value of 1 - 0.025 = 0.975, so X when Z = 1.96.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.96 = \frac{X - 75}{3.9}[/tex]

[tex]X - 75 = 1.96(3.9)[/tex]

[tex]X = 83[/tex]

83 = 6 x 12 + 11.

A height of 6'11'' would be needed.

The quadratic equations that have real roots are [tex]-2x^2+3x+4 = 0[/tex] and  [tex]2x^2+x-6 = 0[/tex].

The value of a discriminant of a quadratic equation shows how many roots f(x) have. If the value of the discriminant is greater than 0 then the quadratic equation has real and distinct roots and if the value of the discriminant is equal to 0, then the quadratic equation has real and same roots.
