Answer:

<MQP = 138 degrees

Step-by-step explanation:

5x + 19 = 2x + 49

5x - 2x = 49 - 19

3x = 30

x = 30/3

x = 10

2 (<MQN) = 5(10) + 19 = 69 * 2 = 138 degrees

Answer:

we get $812.95:  total cost

Step-by-step explanation:

The sales tax on this $750.99 camera is found as follows:  0.0825($750.99) = $61.96.  Adding this amount to the $750.99 price, we get $812.95:  total cost.

A faster way to calculate the total cost is to multiply $750.99 by (1.0825):  again we get $812.95

Answer:

[tex]P(Y|X)=\frac{P(Y\cap X)}{P(Y)} \\ P(Y\cap X) = P(Y)P(Y|X) \\ = 0.45 \times 0.25 \\ \boxed{P(Y\cap X) =0.1125} \\ P(Y\cup X) = P(Y) + P( X) - P(Y\cap X) \\ = 0.45 + 0.35 - 0.1125 \\ \boxed{P(Y\cup X) =0.6875}[/tex]

Step-by-step explanation:

[tex]{\large{\boxed{\mathfrak{Question}}[/tex]

A plane's average speed when flying from one city to another is 550 mi/h and is 430 mi/h on the return flight. To the nearest mile per hour, what is the plane's average speed for the entire trip?

[tex]{\large{\boxed{\mathfrak{Formula}}}[/tex]

The formula to find the average speed is distance divided by time

[tex]{\large{\boxed{\mathfrak{Equation\:to\:find\:average\:speed}}}[/tex]

Let a be the average speed

[tex]\frac{1}{550}+\frac{1}{430} =\frac{2}{a}[/tex]

Since we don't want our denominator's we will get rid of them by multiplying the [tex]LCM[/tex] between the two numbers.

Definition of LCM - The smallest quantity that is divisible by two or more given quantities, also known as Least Common Multiple

Multiply both sides by [tex]23650a[/tex] since that is our LCM.

Now our equation is

[tex]43a+55a=47300[/tex]

[tex]{\underline{simplify}}[/tex]

[tex]98a=47300[/tex]

Since we want to isolate the average speed on one side or also known as [tex]a[/tex] we will divide both sides by 98

[tex]a=482.653[/tex] miles per hour

[tex]{\large{\boxed{\mathfrak{Answer}}}[/tex]

Our average speed is [tex]482.653[/tex] miles per hour or [tex]483[/tex] miles per hour

The first term is 3 and the explicit rule for the given geometric sequence is 3 × [tex]5^{n-1}[/tex].

A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.

For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.

As per the given GP series,

3,15,75,375, 1,875​

The common ratio r = 15/3 = 5

First term a = 3

The nth term is given as a[tex]r^{n-1}[/tex]

Therefore,

The nth term will be as, 3 × [tex]5^{n-1}[/tex]..

Hence "The first term is 3 and the explicit rule for the given geometric sequence is 3 × [tex]5^{n-1}[/tex]".

Answer:

n = 6 1/3

Step-by-step explanation:

"Product" means to multiply

Can be written as 6 x n = 38 or 6n = 38

6n = 38

6n/6 = 38/6

n = 6 2/6

n = 6 1/3

If the product of 6 and a number is 38 then the number 'x' is equal to 6.33.

Let's denote the unknown number as 'x'. According to the given information, the product of 6 and 'x' is equal to 38. We can express this mathematically as:

6x = 38

To find the value of 'x', we need to isolate it on one side of the equation. We can achieve this by dividing both sides of the equation by 6:

6x/6 = 38/6

Simplifying the equation, we have:

x = 6.33

Therefore, the number 'x' is equal to 6.33.

It's important to note that in this case, the number 'x' is not an integer but a decimal value. The equation 6x = 38 represents a proportional relationship, where 6 times the value of 'x' equals 38. By dividing both sides by 6, we solve for 'x' and determine that it is approximately 6.33.

Answer:

26/35

Step-by-step explanation:

1. First to divide the 3 1/2 by 2 3/5 you have to turn them both into improper fractions

First take 3 1/2. You have to multiply the whole number (3) by the denominator (2) and you would get 6. Then you would add then you add the product (6) to the numerator (1) and get 7.

You keep the denominator the same so the improper fraction is 7/2

Do the same thing to 2 3/5 and the improper fraction is 13/5

2. Now we can divide 13/5 by 7/2 using "keep, change, flip"

Keep: 13/5

Change: division to multiplcation

Flip: 7/2 to make 2/7

Your new equation is 13/5 × 2/7. Multiplcation is easy so you just have to multiply staight across: 13 × 2 and 5 × 7 giving you 26/35

If you divide 35 by 26 you will get 1.34 and a bunch of other numbers but I usually stop at two decimal places

Answer:

A) No solution

Step-by-step explanation:

Given the systems of linear equations, y = 2x + 1 and y = 2x - 1:

Both equations in the system have the same slope, m = 2, thus forming parallel lines.  Since their lines are parallel from each other, then it means that their lines will never intersect.

Therefore, the given systems of linear equation is an inconsistent system that has no solution.

Answer:

1) x = 2

2) x = 7

3) x = 12

4) x = 4

5) x = 8

6) x = 3

Step-by-step explanation:

1) 7x + 9 = 23

(7x + 9) +  (-9) = 23 + (-9)

7x + 9 - 9 = 23 - 9

7x = 14

7x/7 = 14/7

x = 2

2) 5x + 7 = 42

(5x + 7) + (-7) = 42 + (-7)

x = 7

3) 4x+3=51

(4x + 3) + (-3) = 51 + (-3)

4x + 3 - 3 = 51 - 3

x = 12

4) 9x+5=41

(9x + 5) + (-5) = 41 + (-5)

x = 4

5) 4x+2=34

(4x  +  2) + (-2) = 34 + (-2)

x = 8

6) 11x+3=36

(11x + 3) + (-3) = 36 + (-3)

11x + 3 - 3 = 36 - 3

x = 3
