a≈13.27

Step-by-step explanation:

Context for variables

a= Side legth

A=Area

Answer:

1/8

Step-by-step explanation:

( 2^-1 / 2^0) ^3

First simplify inside the parentheses

We know that a^b / a^c = a^(b-c)

2^(-1-0) = 2^-1

( 2^-1 ) ^3

Then we know that a power to a power is

a^b^c = a^(b*c)

2^(-1  *3)

2^ -3

Then a negative exponent makes it a fraction

a^ -b = 1/a^b

1 /2^3

1/8

Answer:

x = 0

y = -4

negative 4 cuz the line goes down, meaning it's negative

Answer:

80 degrees

Step-by-step explanation:

angle 1 is equal to 100 because of the law of exterior angles. And since andgle 1 and 2 make 180 degrees we can subtract 80 from 100 and we get the measure of angle 2. Angle 2 and 4 are the same becasue of the law of adjacent angles.

To determine the amount Jimmy made last week, you will need to calculate the commission he made on his sales and add the $500 to that amount.

Here is the math equation showing this:

($1540 x 0.08) + $500 = $623.20

Jimmy made $623.20 last week.

Answer:

-1/13

Step-by-step explanation:

The slope of a line is calculated as rise/run.

The rise is the difference in y-values, and the run is the difference in x values

slope= y₂ - y₁/x₂ - x₁

let (26 , 7) be (x , y) and (-39 , 12) be (x₂, y₂)

slope= (12 - 7)/ (-39 -26)

        = 5/-65

reduce the fraction to get -1/13

Answer:

( [tex]\frac{1}{2}[/tex], 0 )

Step-by-step explanation:

To find the x- intercepts let y = 0, that is

2x² + 3x - 2 = 0

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 2 × - 2 = - 4 and sum = + 3

The factors are + 4 and - 1

Use these factors to split the x- term

2x² + 4x - x - 2 = 0 ( factor the first/second and third/fourth terms )

2x(x + 2) - 1 (x + 2) ← factor out (x + 2) from each term

(x + 2)(2x - 1) = 0

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

2x - 1 = 0 ⇒ 2x = 1 ⇒ x = [tex]\frac{1}{2}[/tex]

The x- intercepts are (- 2, 0 ), ( [tex]\frac{1}{2}[/tex], 0 )

Answer:

Given b=1.7 and ∠β=39°,

So

x = 2.70133

Answer:

4) Alternate angles

Step-by-step explanation:

Alternate angles are on the opposite corners of the line of the angle, and 10 and 14 are on opposite corners, so that makes them alternate angles. I hope this helped you!

Answer:

Y(4) = 200(1.1)^4

Step-by-step explanation:

Given that :

Number of tickets purchased before consecutive wins = 200

For each consecutive win, ticket purchased increases by a factor of 1.1

Number of tickets after 4 wins

This scenario describes an exponential relation :

Where increase is factor based and not a certain number :

Hence,

Number of tickets, Y= Initial number of ticket * growth factor^number of wins

Hence, we have

Y(n) = 200(1.1)^n

Y(4) = 200(1.1)^4 = 292.82

Answer:

the slope is 2.5

(from x=0 to x=2 it goes up by 5)

-2 is the intercept with the y-Axis

the general formula is:

y = m*x + b

where m is the slope and b the intercept

here you go:

y = 2.5x -2

Answer:

$.40 cents in nickels and $1.50 (or 150 cents) in quarters in total she would have $1.90 in cents he would have 190 cents in total

Step-by-step explanation:

you would do 8x5 to get 0.40 cents and then do 6x25 to get $1.50 so she will

Answer:

$974.50

Step-by-step explanation:

The sales tax is 0.0925($891.99), or $82.51.  We need only add this amount to the listed price ($891.99) to find the total cost with sales tax included:

$891.99

+    82.51

--------------

$974.50

An alternative approach would be to multiply the listed price by 1.0925:

1.0925($891.99) = $974.50

Here the '1' refers to the listed price and the '0.0925' to the sales tax.

Answer:

A = 20.25 sq units

Step-by-step explanation:

to find the area of a square you only need to know the measure of one side -- all other sides will be equal to it

it appears the segment is 4.5 units so you would square that to get the area

A = 4.5²

A = 20.25

Answer:

LM = 8 cm

Step-by-step explanation:

LM = KN = x + 7

NM = KL = x + 7 + NQ = x + 7 + 2 = x + 9

KN×NM = 80

(x+7)(x+9) = 80

x² + 7x + 9x + 63 = 80

x² + 16x + 63 = 80

x² + 16x - 17 = 0

solution of a quadratic equation

x = (-b ± sqrt(b² - 4ac))/(2a)

a=1

b=16

c=-17

(-16 ± sqrt(256 + 4×17))/2 = (-16 ± sqrt(256+68))/2 =

= (-16 ± sqrt(324))/2 = (-16 ± 18)/2

x1 = (-16 + 18)/2 = 2/2 = 1

x2 = (-16 - 18)/2 = -34/2 = -17

x2 as negative value is no valid solution for a side length.

so, only x1 remand as solution.

=> x=1, LM = KN = 1+7 = 8, NM = KL = 1+9 = 10

Step-by-step explanation:

its like a bar graph but joint. theres no space between two consecutive bars

Answer:

A' = (0,0)

B' = (6,-12)

C' = (-12,-12)

Step-by-step explanation:

According to the Question,

A = (0,0)  , B = (2,-4)  , C = (-4,-4)

A = (0,0) becomes A' = (0,0). No change happens. This point is fixed

B = (2,-4) becomes B' = (6,-12). This point does move

C = (-4,-4) becomes C' = (-12,-12). This moves as well

So all you need to do from here is draw triangle A'B'C'.

Answer:

The answer is 1/3.

Step-by-step explanation:

A coin has either heads or tails. The odds of a coin getting heads is 1/2.

There are three equal-sized sections with numbers 3, 6 and 9 on the spinner. There are two sections with numbers greater than 3, which are 6 and 9. The odds of getting a number greater than 3 is 2/3.

To find the overall probability of both incidents occurring, the two fractions are multiplied together, which is 1/2 * 2/3 = 1/3

Answer:

0.333/1/3

Step-by-step explanation:

Well, the probability of getting heads is 1/2 since there are 2 sides to a coin. There are 2 numbers on the spinner greater than three (6,9) which is 2/3.

1/2 times 2/3=0.33. The probability of getting heads and getting a number that is greater than is 0.333 or 1/3.

Answer:

103

Step-by-step explanation:

Find the area of the rectangle on the top

A = 7*13 = 91

Now find the area of the rectangle on the bottom

13 - (5+5) = 3

11-7 = 4

The dimensions of the bottom rectangle are 3 by 4

A = 3*4 = 12

The total area is 91+12 = 103

Answer:

the awnser is c. p-250 + p

Answer: The value of x can be either 5 or 10.

Step-by-step explanation:

We are given:

Total profit, P = $5600

The given equation follows:

⇒ P = 600 + 1500x - 100x²

Putting value of P in above equation, we get:

⇒ -100x² + 1500x + 600 = 5600

⇒ -100x² + 1500x - 5000 = 0

⇒ 100x² - 1500x + 5000 = 0

Solving this equation by middle term split, we get:

⇒ 100(x² - 15x + 50) = 0

⇒ (x² - 10x - 5x + 50) = 0

⇒ x(x - 10) - 5(x -10) = 0

⇒ (x - 10)(x - 5) = 0

⇒ x = 10, 5

Hence, the value of x can be either 5 or 10.

Answer:

Total Volume = 190 m³

Step-by-step explanation:

Volume of the entire figure = L (Area 1  + Area 2)

where L = 10 m

Area 1 (blue prism) = 4 x 3 = 12 m²

Area 2 (brown prism = 1 x 7 = 7 m²

plugin  values into the formula:

Volume of the entire figure = L (Area 1  + Area 2)

                                            = 10 (12 + 7)

                                            = 120 m³ + 70 m³

                                            = 190 m³
