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:

3(x-7) – x=2x-21 ( the equation)

--> infinitely many solutions

Step-by-step explanation:

The solution of the equation is infinitely many solutions, the correct option is C.

In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

We are given that;

Equation 3(x-7) – x=2x-21

Now,

To solve the equation, we need to simplify both sides and isolate x. We can do this by following these steps:

3(x-7) – x = 2x - 21 Expand the parentheses by multiplying 3 with x and -7:

3x - 21 - x = 2x - 21 Combine like terms on the left side by subtracting x from 3x:

2x - 21 = 2x - 21 Subtract 2x from both sides to eliminate x:

-21 = -21 This equation is always true, regardless of the value of x. This means that the equation has infinitely many solutions. Any value of x will satisfy the equation

Therefore, the answer of the given equation will be  infinitely many solutions

Step-by-step explanation:

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

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:

Amy had 4 erasers. Brianna gave her x more erasers which doubled the amount of erasers she had. How many erasers does Amy have in total?

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. In case the value of the discriminant is less than zero then the quadratic equation will have no real roots.

In order to know if the quadratic equation has real roots or not, we need to find the discriminant of the given quadratic equations,

A.) [tex]-x^2+2x -6 = 0[/tex]

Here, a= -1, b=2 and c=-6

[tex]D = b^2 -4ac[/tex]

[tex]D = 4 -24\\D = -20[/tex]

As the value of the discriminant is negative it will not have real roots.

B.) [tex]-2x^2+3x+4 = 0[/tex]

Here, a= -2, b=3 and c=4

[tex]D = b^2 -4ac[/tex]

[tex]D = 9 +32\\D = 41[/tex]

As the value of the discriminant is positive it will have real roots.

C.) [tex]2x^2+x-6 = 0[/tex]

Here, a=2, b=1 and c=-6

[tex]D = b^2 -4ac[/tex]

[tex]D = 1 +48\\D =49[/tex]

As the value of the discriminant is positive it will have real roots.

A.) [tex]2x^2 -x+3 = 0[/tex]

Here, a=2, b=-1 and c=3

[tex]D = b^2 -4ac[/tex]

[tex]D = 1-24\\D = -23[/tex]

As the value of the discriminant is negative it will not have real roots.

Solution:

The least possible number of steps will be the lowest common multiples of these sets of steps.

We want fractions that will give whole numbers because realistically, one cannot take half a step of a step.

 So, the number of steps must be a multiple of denominators of the fractions given.

   Denominators are 2 , 3 and 8

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

Step-by-step explanation:

Convert the decimal number to a fraction by placing the decimal number over a power of ten. Since there are  2   numbers to the right of the decimal point, place the decimal number over  10 ^2  ( 100 ) . Next, add the whole number to the left of the decimal.

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.

To find : what is the number.

Solution : We have given if you multiply a number by 3 and then subtract 5, you will get 40.

According to question :

Let the number =  x

Multiply is with 3 = 3x

Subtract 5 from it we get 40 .

3x -5 = 40

On adding both sides by 5

3x = 45 .

On dividing both sides by 3

x =  15.
