Answer:

Step-by-step explanation:

Step one:

we are told that their joint amount is $62

let John's amount be x

and Pedro's amount be y

so that y=x+15

Step two:

The equation to represent the situation is

62=x+(x+15)

open the bracket and solve for x we have

62=x+x+15

62=2x+15

2x=62-15

2x=47

divide both sides by 2

x=47/2

x=23.5

John has $23.5

Answer:

B

Step-by-step explanation:

f(x)=x (slope is 1, y-intercept is zero)

g(x) = (1/3)x (slope is (1/3), y-intercept is zero)

(1/3)x = (1/3)f(x)

Answer:

B

Step-by-step explanation:

as u notice the slop of f function is higher than g function so g(x) is approximately one third of function f and there are no shifts in g(×) so no need for sum of subtract .

From the question, we are informed that 1/3 of gym members say they spent 5 hours per week at the gym.

Assuming there are 150 people working out at the gym, the number of people that'll most likely spend 5 hours at the gym this week will be calculated by multiplying 1/3 by 150. This will be:

= 1/3 × 150

= 50 people

Answer:

Option (D)

Step-by-step explanation:

Formula to get the average rate of change of the function f(x) between two points x = a and b is,

Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]

We have to calculate the average rate of change between x = 0 and x = 2.

From the graph attached,

f(0) = -2

f(2) = 6

Therefore, average rate of change = [tex]\frac{6-(-2)}{2-0}[/tex]

                                                          = [tex]\frac{8}{2}[/tex]

                                                          = 4

Option (D) will be the correct option.

Step-by-step explanation:

Oops I meant "there are 3! = 6 ways to permute ABTS that have TS."

There are 12 different combinations to display marvel that doesn't involve Steelie and the tiger.

A permutation is an orderly arrangement of things or numbers. Combinations are a means to choose items or numbers from a collection or set of items without worrying about the items' chronological order.

Given, Zara has a collection of 4 marbles: an Aggie, a Bumblebee, a Steelie, and a Tiger. She wants to display them in a row on a shelf but does not want to put the Steelie and the Tiger next to one another.

We want the number of ways to permute the string ABST that has S and T separated.

Total ways of displaying marbles = 4! = 24

If S and T are together, then the permutation contains the consecutive pair ST or TS somewhere. We can count these possibilities by regarding ST or TS as a single symbol

permutation of getting them together = 2 * 3!

permutation of getting them together = 12

Thus,

total desired combination = Steelie and tiger do not come together

total desired combination = 24 - 12 = 12

therefore, There are 12 possible combinations of displaying marvel without making Steelie and tiger together.

Answer:

The correct options are presented as follows;

ΔABC is reflected across the y-axis to become ΔA'B'C' is rotated 90° counterclockwise about the origin to become ΔA''B''C''. Because the transformations are rigid transformations the preimage and image are congruent

Step-by-step explanation:

The coordinate of the preimage point A = (-2, 1)

The coordinate of the image point A' = (2, 1)

Similar for points B(-5, -2) and B'(5, -2), C(-3, -4) and C'(3, -4)

Which is equivalent to a reflection across the y-axis

Similarly, we have;

The coordinate of the preimage point A' = (2, 1)

The coordinate of the image point A'' = (-1, 2)

Which is equivalent to rotation of 90° counterclockwise which involves transforming a preimage (x, y) to an image (-y, x)

Similar for points B and B', C and C'

Therefore, because the reflection transformation, and the rotation transformation, are rigid transformation, the figures of the preimage and the image are congruent

Therefore, we have;

ΔABC is reflected across the y-axis to become ΔA'B'C' is rotated 90° counterclockwise about the origin to become ΔA''B''C''. Because the transformations are rigid transformations the preimage and image are congruent.

Answer:

0.22 miles

Step-by-step explanation:

Let

A = Distance pumpkin A travels = 0.61 miles

Distance pumpkin B travels is 0.28 mile farther than Pumpkin A

[tex]B=0.28+A\\\Rightarrow B=0.28+0.61\\\Rightarrow B=0.89\ \text{miles}[/tex]

Distance pumpkin B travels is 0.06 miles further than pumpkin C

[tex]B=0.06+C\\\Rightarrow C=B-0.06\\\Rightarrow C=0.89-0.06\\\Rightarrow C=0.83\ \text{miles}[/tex]

To calculate how much farther pumpkin C travels than pumpkin A we have the subtract their distances

[tex]C-A=0.83-0.61=0.22\ \text{miles}[/tex]

So, pumpkin C traveled 0.22 miles more than pumpkin A.

Answer:

-2 and 2

Step-by-step explanation:

When you look at the graph, you see that the line is in a U shape. We are trying to see what the value of g(x)=4. Since g is represented by the graph, the equation equals 4. The 4 in the equation is positive so you would look at the graph for a positive 4. There are 2 positive 4's on the graph; one on the x axis and one on the y axis. If you look at the U-shaped line, you see that it passes the 4 on the y axis. (the point -2,4 has the 4 as y and the point 2,4 has 4 as y). This makes the answer -2 and 2 because both the numbers have 4 as the y when you put them as points.

components: LeftAngleBracket 16, 11 RightAngleBracket distance: 194.16 yards

Step-by-step explanation:

get her done!!! Correct on Edge 2020

The vector represents the path from the house to the park is components: {16,11} and actual distance between them is 194.16 yards. So, option A is correct.

The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.

|AC|^2 = |AB|^2 + |BC|^2    

In order to find the length of a point to another point that has different y and x points, we will use the pythagorean theorem

(a^2 + b^2 = c^2)

Here, 16 and 11 are the distances from her house,

16^2 + 11^2 = c^2

c^2 = 377

c = 19.416...

Now, we have to convert this to yards;

19.416 x 10 = 194.16 yards

Hence, the vector represents the path from the house to the park is components: {16,11} and actual distance between them is 194.16 yards.

So, option A is correct.
