A mistake was made in the steps shown to simplify the expression. Which step includes the mistake?

Answer:

b=3

Step-by-step explanation:

When multiplying square roots, you multiply numbers inside the radical.

S

[tex] \sqrt{3} \times \sqrt{6} = \sqrt{18} [/tex]

Next, simplify the answer, and you will get

[tex]3 \sqrt{2} [/tex]

giving 3 as your b value.

Answer:

60

Step-by-step explanation:

horizontal plane = 180

therefore 180 - b + 27 = 180

this will give us the missing inner angle

then we create a linear equation to get the value of b, and since the sum of the inner angles of the triangle = 180

b - 7 + b - 26 + (180 - 27 - b) = 180

b = 60

Answer:

Below in bold.

Step-by-step explanation:

The expression is:-

f(h) = 16(h + 5) - 4

When h = 92:

f(92) =  16(92 + 5) - 4

= 16 * 97 - 4

= 1552 - 4

= 1548.

Answer:

The ___a_ value of the quadratic function determines whether the parabola opens upward or downward.

Answer:

The 'a' value.

Step-by-step explanation:

The general quadradic equation is:

[tex]ax^2 + bx + c; \text{ } a\neq 0[/tex]

If the value of a is greater than 0, then the parabola would open upward. If the value of a is less than 0, then the parabola would open downward.

Answer:

The answer is yes, when two improper fractions is multiplied, the product will always be more than one.

Because when you convert an Improper fraction, the decimal value of it is always more than 1. Thus any improper fraction, added or multiplied with each other the answer will always be more than 1.

Example:

5/ 2 = this is an improper fraction. To convert it into decimal divide the denominator from the numerator

=> 5 / 2

=> 2 1/2

Answer:

A

Step-by-step explanation:

A is correct because if the minimum is 29,000 feet, x (the airplane altitutude) must be greater than or equal to 29,000 ft. Since the maximum is 41,000 feet, x must be less than or equal to that number.

Answer:

The triangle is not acute because 2^2 + 4^2 < 5^2

Step-by-step explanation:

2^2 is side a,

4^2 is side b,

5^2 is side c,

then

c^2 = a^2 + b^2 is right triangle

c^2 > a^2 + b^2 is obtuse

c^2 < a^2 + b^2 is acute

If we insert the numbers into the equation and square them:

c^2 = a^2 + b^2

25 = 4 + 16

25 > 20

This means the triangle is NOT accute, but obtuse

Therefore, it means the triangle is not acute, but obtuse

i.e.,

[tex]a^2 > b^2+c^2\\\\5^2 > 2^2+4^2[/tex]

What is the acute angle?

An angle is formed when two rays meet at a vertex. When this angle measures less than [tex]90[/tex] degree, it is termed an acute angle.

As per the Pythagoras theorem the triangle is acute only if the square of the longest side is less than the sum of the squares of the two smaller sides.

i.e., [tex]a^2 < b^2+c^2[/tex]

where [tex]a,b,c[/tex] are the lengths of the sides of a triangle.

So,

[tex]a^2=5^2\\b^2=2^2\\c^2=4^2[/tex]

Then,

The right triangle is [tex]a^2=b^2+c^2[/tex].

The obtuse triangle is [tex]a^2 > b^2+c^2[/tex]

The acute triangle is [tex]a^2 < b^2 + c^2[/tex]

i.e.,

[tex]5^2 = 2^2+4^2\\\\25=4+16\\\\25 > 20[/tex]

Hence, this means the triangle is not acute, but obtuse.

Answer:

About $16.42

Step-by-step explanation:

Since you know the overall price of 5 cans of pinto beans is 3.35, you divide 5 by 3.35, to get the price of one can.

5 / 3.35 = 1.49, giving you the price of one can of pinto beans

You then multiply this number by 11, which gives you 16.42 (rounded)

The equation is given by:

 9-1/3x = 7      

Step-by-step explanation:

Let the number be denoted by x.

Now, we are given a word phrase as follows:

One-third of a number less than nine is equal to seven.

Now this word phrase could be mathematically expressed as a equation by:

 one-third of x is: 1/3 x

and this number less than 9 is given by:

 9-1/3x

Now, this number is equal to 7.

i.e. we finally have:

 9-1/3x = 7    

Answer:

In two years, George will be 8 years old.

Step-by-step explanation:

g = 3s

(g + 2) / 2 = a + 2

g + 2 = 2 (s + 2)

g + 2 = 2s + 4

g = 2s + 2

3s = 2s + 2

s = 2

g = 3s

g = 3 (2)

g = 6

6 + 2 = 8

Step-by-step explanation: its y2-y1 over x2-x1

Answer:

Part A:

The Standard Form equation of a line has the following formula:

Ax+By=C, where A, B, and C are integers, and A is non-negative.

We will assume that when renting a boat Sam paid fixed cost and rental charge per day.

y = the total rent

x = the number of days

Sam rented a boat at $225 for 2 days would mean:

y = 225 when x = 2 or if we plug into Ax+By=C:

2A + 225B = C since A is non-negative we divide both sides by A

2 + (B/A)225 = C/A

He rents the same boat for 5 days, he has to pay a total rent of $480 means:

y = 480 when x = 5 days

5A + 480B = C since A is non-negative we divide both sides by A

5 + (B/A)480 = C/A

Now we have:

2 + (B/A)225 = C/A

5 + (B/A)480 = C/A

Lets denote s = B/A  and t = C/A. Now we can write the following system of equations:

2 + 225s = t

5 + 480s = t

........

........

s = -1/85

t = -11/17 = -55/85

Now we can go back to:

B/A = -1/85 and C/A = -55/85

A = 85, B = -1, C = -55

The standard equation is:

85x - y = -55

Part B:

Using the equation 85x - y = -55 we solve for y

.......

click here to see the equation solved for y

........

y = 85x + 55

or in function notion y = f(x)

f(x) = 85x + 55
