Step-by-step explanation:

Given:

Half of the granola served with breakfast.

Let the amount of Granola present initially = [tex]x[/tex] kg

Half of it ([tex]\frac{x}{2}[/tex]) served with breakfast, so remaining granola :

[tex]x-\dfrac{x}{2} = \dfrac{x}{2}[/tex]

After dinner, the remaining granola 6,250 gm granola was served with yogurt dessert.

First of all, let us convert it to kilogram because the answer is required in Kilograms.

We know that:

1000 gms = 1 kilograms

1 gms = 0.001 kilograms

6250 gms  = 6250 [tex]\times[/tex] 0.001 = 6.250 kilograms

Now, as per given question statement:

[tex]\dfrac{x}{2} = 6.250\ kg\\\Rightarrow x = 2 \times 6.250\\\Rightarrow \bold{x = 12.5\ kg}[/tex]

So, the answer is:

Girl scout camp started with 12.5 Kilograms of granola.

Answer:

[tex]P(T_1\ n\ T_2) = \frac{2}{21}[/tex]

Step-by-step explanation:

From the comments in your question; we have

Stars = 4

Triangles = 5

Circles = 3

Squares = 3

Required  

Determine the probability of both shapes being triangles

First, calculate the total

[tex]Total = 4 + 5 + 3 + 3[/tex]

[tex]Total = 15[/tex]

Next, calculate the probability of the first selected shape being a triangle;

P(T₁) = Number of triangles divided by total number of shapes

[tex]P(T_1) = \frac{5}{15}[/tex]

[tex]P(T_1) = \frac{1}{3}[/tex]

Next, calculate the probability of the second selected shape being a triangle;

P(T₂) = Number of triangles divided by total number of shapes

Because it's probability without replacement. the number of triangle left is 4 and the number of shapes left is 14;

So:

[tex]P(T_2) = \frac{4}{14}[/tex]

[tex]P(T_2) = \frac{2}{7}[/tex]

Hence:

[tex]P(T_1\ n\ T_2) = P(T_1) * P(T_2)[/tex]

[tex]P(T_1\ n\ T_2) = \frac{1}{3} * \frac{2}{7}[/tex]

[tex]P(T_1\ n\ T_2) = \frac{2}{21}[/tex]

Hence, the required probability is [tex]\frac{2}{21}[/tex]

Answer:

2/21

Step-by-step explanation:

There are 4 stars, 5 triangles, 3 circles, and 3 squares

For the first drawing there are 5 triangles and a total of 15 shapes.

p(first triangle) = 5/15 = 1/3

Since there is no replacement, for the second drawing, and one triangle has been taken, now there are 4 triangles left and 14 total shapes left.

p(second triangle) = 4/14 = 2/7

p(two triangles) = p(first triangle) * p(second triangle)

p(two triangles) = 1/3 * 2/7

p(two triangles) = 2/21

===========================================

Plug in x = 0

f(x) = 2x^2 + 5

f(0) = 2(0)^2 + 5

f(0) = 5

Plug in x = 2

f(x) = 2x^2 + 5

f(2) = 2(2)^2 + 5

f(2) = 13

Now use the formula below to find the average rate of change (AROC) from x = a to x = b

AROC = ( f(b) - f(a) )/( b-a )

AROC = ( f(2) - f(0) )/( 2-0 )

AROC = ( 13 - 5 )/( 2 - 0)

AROC = 8/2

AROC = 4

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

This is the same as finding the slope of the line through (0,5) and (2,13)

m = (y2 - y1)/(x2 - x1)

m = (13-5)/(2-0)

m = 8/2

edge2021

The height Abby climb above their original starting position is 20 feet.

Suppose the considered function whose graph is to be made is

f=f(x) f(x)

The values of 'x' (also called input variable, or independent variable) are usually plotted on horizontal axis, and the output values

f=f(x) f(x)

are plotted on the vertical axis.

They are together plotted on the point

f(x)) (x,y) = (x, f(x))

This is why we usually write the functions as:

f(x) y = f(x)

We are given that;

Time= 12min

Now,

To find how high Abby climbed above their original starting position, we need to look at the graph and find the highest point of Abby’s climb.

We can see that Abby’s climb is represented by the blue line on the graph.

The highest point of Abby’s climb is at (6, 22), which means that after 6 minutes, Abby reached a height of 22 feet.

Since the original starting position is at (0, 2), which means that at the beginning, Abby was at a height of 2 feet, we can subtract 2 from 22 to find how high Abby climbed above their original starting position.

Abby climbed 22 - 2 = 20 feet above their original starting position.

Therefore, by the graph the answer will be 20 feet.

Answer:

[tex]y=-\frac{2}{3}x+12[/tex]

Step-by-step explanation:

Step 1: Rule out answers

The answer cannot be B or D because the y-intercept is at 12(b = 12) and in a linear equation y=mx+b, b is the y intercept.

B has the y intercept at 18

D has the y intercept at 18

Step 2: Find the slope

The slop is the change in y over the change in x.  We can also write this as [tex]\frac{rise}{run}[/tex]

We see it lowers by 2 so we will put -2 as the numerator

We also the x value increase by 3 every time it gets lowered by 2 so the run is 3

Therefore the slope is [tex]-\frac{2}{3}[/tex]

Step 3: Plug in the the variables to get the linear equation

[tex]y=mx+b[/tex]

[tex]y=-\frac{2}{3}x+12[/tex]

Therefore the answer is A. [tex]y=-\frac{2}{3}x+12[/tex]

Answer:

[tex]\Large \boxed{{y=-\frac{2}{3}x +12}}[/tex]

Step-by-step explanation:

y = mx + b (slope-intercept form of a line)

m is slope

b is y-intercept

The y-intercept of the line is (0, 12) or 12.

y = mx + 12

The slope of the line can be found through rise over run.

(0, 12) and (18, 0) are two points on the line.

m = (y2-y1)/(x2-x1)

m = (0-12)/(18-0)

m = -12/18

m = -2/3

The slope of the line is -2/3.

y = -2/3x + 12

Answer:

Student Ticket: $8

Adult $28

Step-by-step explanation:

To find out the price of each ticket create 2 equations, then solve for x & y

x = student tickets

y = adult tickets

25x + 28y = 984

25x + 25y = 900

To do this first put x on one side of the equation

25x = 900 - 25y

x = 36 - y

Now substitute this equation in x for the first equation

25(36 - y) + 28y = 984

Now distribute 25 in 36 - y, 900 - 25y + 28y = 984

After this combine like term, then subtract 900 from each side, 3y = 84

Then divide 3 on each side, y = 28

Lastly substitute 28 for y in any equation to solve for x, x = 8

x & y are the price of each ticket

Step-by-step explanation:

3 x 2

Mike: From the school to the mall, we could count out 16 units. From the mall to the library, we could count out 29 units. When we add 16 and 29, we get the distance Mike traveled: 45 units.

Henry: He traveled from the school to the library. To find out how long this distance is, we look at our previous numbers. From the school to the mall: 16. From the mall to the library: 29

To solve, we need to know the Pythagorean Theorem. We use the formula a^2 + b^2 = c^2. Here, 16 is a and 29 is b. We need to square both numbers and add them together to get c^2.

[tex]16^2=256\\29^2=841\\256+841=1097\\1097=c^2[/tex]

Then, we have to square 1097 to find c.

√1097 ≈ 33

Total: We subtract Henry's distance from Mike's to get our final answer.

45 - 33 = 12

Mike traveled 12 more units than Henry.

Answer:

The correct option;

136 cubic inches

Step-by-step explanation:

The dimension of the rectangular flour canister are;

Length = 5 1/2 inches (5.5 inches)

Width = 4 inches

Height = 10 inches

The dimensions of the smaller sugar canister

Length = 3 1/2 inches (3.5 inches)

Width = 3 inches

Height = 8 inches

The volume of a cube is given by the relation;

V = Length × Width × Height

Therefore, we have;

The volume of the rectangular flour canister  = 5 1/2 × 4 × 10 = 220 in³

The volume of the rectangular sugar canister  = 3 1/2 × 3 × 8 = 84 in³

The difference in volume between the two canisters = 220 in³ - 84 in³ = 136 in³

The difference in volume between the two canisters = 136 in³

Answer: [tex]x = \frac{\pi}{4} \ \text{radians}, \ \ y = \frac{\sqrt{2}}{2}[/tex]

Note: pi/4 radians is equal to 45 degrees

===========================================

To get this answer, you can use the unit circle to see that at 45 degrees or pi/4 radians, the sine and cosine value are both [tex]\frac{\sqrt{2}}{2}[/tex]

You could also use your calculator to graph y = sin(x)-cos(x) to find the x intercept in the interval [tex]0 < x < \frac{\pi}{2}[/tex] to find the approximate x intercept to be x = 0.70710678

Then note how [tex]\frac{\sqrt{2}}{2} \approx 0.70710678[/tex]

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

Or you could do the following steps

sin(x) = cos(x)

sin^2(x) = cos^2(x)

sin^2(x) = 1 - sin^2(x)

sin^2(x) + sin^2(x) = 1

2sin^2(x) = 1

sin^2(x) = 1/2

sin(x) = sqrt(1/2)

sin(x) = sqrt(2)/2

Again you'll have to turn to the unit circle, or some reference sheet, to determine the x value that makes the last equation above to be true. That x value is x = pi/4 radians.
