Hello there! Slope is rise/run. The formula for finding slope is y2 - y1 / x2 - x1, where you subtract the first x and y-coordinates from the second x and y-coordinates. In other words, the order that the coordinates show up for this problem will be used in that order. For this case, here are the numbers that will be used for each.

y2: 5
y1 : -33
x2: 47
x1: -19

Let's plug it in to get 5 - (-33) / 47 - (-19). Now, let's subtract. Just by looking at the numbers, we will actually be adding the numbers, because when you add a negative number, you actually add. So 5 + 33 is 38. 47 + 19 is 66. 38/66 is 19/33 in simplest form. There. The slope of the line is 19/33.

The height of a square pyramid-shaped gift box is one half the length of
Schach [20]

Answer:

15 inches

Step-by-step explanation:

Volume of a squre based pyramid :

V = a²(h/3)

a = base edge ; h = height

h =1/2 a

V = 4500

4500 = a² * (1/2a) ÷ 3

4500 = a² * a/2 * 1/3

4500 = a³/2 * 1/3

4500 = a³ / 6

27000 = a³

27000 = a³

Take the cube root of both sides

(27000)⅓ = a

30 = a

Recall:

h = 1/2a

h = 1/2(30)

h = 15 inches

Eleven is 20% of ____
ollegr [7]

Convert to a decimal which would be 0.55 (11/20).


Then you want to multiply 0.55 by 100 (which is a whole number, all % is going to come from 100) to convert to a full % -> 0.55*100


Then you will simplify 0.55*100


You answer will be 55%.

There are a total of 84 students in a robotics club in the science club. The science club is 12 more students in the robotics cl
Anna [14]

Answer:


Step-by-step explanation:

Let the Number of students in the Robotics club be x

So , the number of students in the Science club must be x+12

(Because it is given that the science club have 12 more students.)

Total number of students = 84

So ,

x+(x+12)=84

combining the like terms we get

2x+12=84

Subtract 12 from both sides

2x=72

Divide both sides by 2

x=36

So ,


Number of students in the Robotics club = 36

Number of students in the Science club =36+12 = 48

The population of a city can be modeled by P(t) 3810(1.0005)7t , where P(t) is the population after t years. Which function is a
swat32

Answer:

P(t) = 3810(1.0035)^{t}

Step-by-step explanation:

Given:

P(t) = 3810(1.0005)^{7t}             -----(1)

Simplifying (1.0005)^{7t}

From Law of indices, x^{mn} = (x^{m})^{n}

(1.0005)^{7t} = (1.0005^{7})^{t}

When 1.0005 is raised to the 7th power, it is approximately 1.0035.

Substituting (1.0005)^{7t} = (1.0035)^{t} into equation(1)

P(t) = 3810(1.0035)^{t}
