Answer:

The slope is 4/5 and the y intercept is -3

Step-by-step explanation:

The equation is in slope intercept form

y= mx+b where m is the slope and b is the y intercept

y = 4/5x -3

The slope is 4/5 and the y intercept is -3

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:

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:

A = 68

B = 44

Step-by-step explanation:

The sum of the angles of a triangle add to 180

A+B+C =180

x + x-24 +68 = 180

Combine like terms

2x+44 =180

Subtract 44 from each side

2x+44-44= 180-44

2x = 136

Divide by 2

2x/2 = 136/2

x = 68

A = x = 68

B = x-24 =44

Answer: I’m confused with A but I’m 100% sure B is 44 I hope this helped

4 7/6

This is an improper fraction

4 6/6 + 1/6

5 1/6

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:

$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:

( [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:

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:

12,400

Step-by-step explanation:

Let the current employees be x

65% increase in number = 0.65x

If the total number of employees after the increase is 20,460, then;

x + 0.65x = 20,460

1.65x = 20,460

x = 20,460/1.65

x = 12,400

Hence the current number of employees is 12,400

Answer:

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

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

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:

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:

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:

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.
