Part A: In the first box, enter an equation to represent the distance, d, that Ms. Chung drives to work. Part B: In the second box, enter the distance Ms. Chung drives to work.

Answers

Answer 1

A) The algebraic expression will be 12d + 7 = 91

B) He drives 7 miles per day to work.

For 11 days straight, Ms. Chung drove the same distance every day going to and coming from work.

The distance she drove on Saturday was; 0.9 miles.

The number of miles she drives per day:

84 miles/12

= 7 miles per day

Let the number of miles she travels be day = d

12d + 7 = 91 miles

12d + 7 = 91

12d = 91 - 7

12d = 84

d = 84/12

d = 7 miles per day

In one part of a rainforest in South America, 3/5 of the frogs are poisonous. What fraction of the frogs are not poisonous?

Answers

2/5 of the frogs in that portion of the South American rainforest are not poisonous.

How to calculate the fraction of frogs that are not poisonous in South American rainforest

On the off chance that 3/5 of the frogs in a rainforest in South America are poisonous, at that point, the remaining division speaks to the frogs that are not poisonous.

To discover this division, we subtract the division of poisonous frogs from 1 (which speaks to the complete):

1 - 3/5 = 5/5 - 3/5 = 2/5

Hence, 2/5 of the frogs in that portion of the rainforest are not poisonous. This fraction represents the parcel of frogs that don't have poisonous characteristics.

Based on these results how

Answers

We can expect 258 blocks in the bag to be green.

We have to given that,

A bag has 6 blocks in it. Jerry picks a block out of the bag 60 times. He gets the green block 43 times.

Since, We know that Jerry picked a block out of the bag 60 times, and got the green block 43 times.

So the probability of picking a green block is:

P = 43/60

P = 0.7167

This means that out of every 60 blocks picked, there are 43 green.

Now, For this probability to estimate the number of green blocks in the bag.

since, Jerry picked 60 blocks 6 times

When, we assume that the bag contains a total of 360 blocks , we can multiply this total by the probability of getting a green block:

360 x 0.7167 = 258.012

It takes 9 hours for 4 roofers to complete a certain job. How long would it take 6 roofers to complete the same job?
hours

Answers

Answer:

6 hours

Step-by-step explanation:

Varying inversely simply means using the "inverse proportion" method

So therefore,

4 roofers= 1 hour

1 roofer= 9 * 4

= 36 hours

Why? Because the lesser amount of workers you have, the more time will be needed so as to complete the work.

6 roofers= 36/6=6 hours

The more people you have, the lesser amount of time will be spent on completing the work.

Answers

The rigid transformations that can take AEFD to CFEB are translation, rotation, and reflection.

To describe the rigid transformations that take polygon AEFD to CFEB, we need to identify the transformations that preserve the shape and size of the polygon. Here are some possibilities:

Translation: A translation involves moving the entire polygon without changing its orientation or shape. If we shift polygon AEFD to the right, it will align with polygon CFEB. Therefore, translation is one way to achieve this transformation.

Rotation: If we rotate polygon AEFD around a fixed point, such as the center of the polygon or a vertex, by a certain angle, it can align with polygon CFEB. A rotation preserves the shape and size of the polygon.

Reflection: A reflection involves flipping the polygon across a line, resulting in a mirror image. If we reflect polygon AEFD across a line of reflection, it can match polygon CFEB.

Graph the circle (x - 3)^2 + (y + 3)^2= 36.

Answers

The circle on a graph by drawing the center point and then drawing a circle around it with a radius of 6.

To graph the circle with the equation (x - 3)² + (y + 3)² = 36, we can start by finding the center and radius of the circle.

The equation of a circle in standard form is (x - h)² + (y - k)² = r² (h, k) represents the center of the circle and r represents the radius.

Comparing the given equation with the standard form, we can see that the center of the circle is (3, -3) and the radius is √36 = 6.

Using this information, we can proceed to plot the circle on a graph:

Plot the center point: (3, -3).

From the center point, move 6 units in each direction (up, down, left, and right) to determine the points on the circle.

Up: (3, -3 + 6) = (3, 3)

Down: (3, -3 - 6) = (3, -9)

Left: (3 - 6, -3) = (-3, -3)

Right: (3 + 6, -3) = (9, -3)

Connect the plotted points to form a circle.

The resulting graph should look like this:

B √1/9

Please explain the answer my radical calculator doesn't work on anything with letters in it.​

Answers

Answer: C 1/6*√2n

Step-by-step explanation:

• Simplify √n/18 as (1/3)^2*n/2

• Multiply them under the radical so the squares 1/3 cancels out to 1/3*√n/2

• Multiply the √n/2 on both sides as √2*n/√2*√2 so it comes out to √2n/2

• Multiply √2n/2 with 1/3 to make √2n/6

√2n/6 is equal to 1/6*√2n

The radical expression √n/18 when simplified is 1/3√n/2

Simplifying the radical expression

From the question, we have the following parameters that can be used in our computation:

√n/18

Express 18 as 9 * 2

So, we have the following representation

√n/18 = √n/(9 * 2)


Rewrite as

Take the square root of 9

Write an exponential growth model giving the earning y (in millions of dollars) t years after 2015. Write the base of the model as a decimal

Answers

The exponential growth model for the baseball player's earnings, in millions of dollars, t years after 2015 is[tex]y = 3 \times (1.04)^t,[/tex]  with a base of 1.04.

To model the exponential growth of the baseball player's earnings, we can use the formula:

[tex]y = a \times (1 + r)^t[/tex]

where:

y represents the earning in millions of dollars

a represents the initial earning in millions of dollars (in this case, $3 million)

r represents the growth rate per year (4%, which can be expressed as 0.04)

t represents the number of years after 2015

In this case, we want to find the earning y (in millions of dollars) t years after 2015.

Since the initial earning in 2015 is $3 million, we can substitute a = 3.

Therefore, the exponential growth model for the player's earnings is:

[tex]y = 3 \times (1 + 0.04)^t[/tex]

Simplifying the expression further, we have:

[tex]y = 3 \times 1.04^t[/tex]

The base of the model is 1.04, which is the decimal representation of the growth rate (4%).

Using this model, we can calculate the player's earnings for any year after 2015 by plugging in the value of t.

For example, if we want to find the earnings 5 years after 2015, we substitute t = 5 into the equation:

[tex]y = 3 \times 1.04^5[/tex]

This will give us the projected earnings in millions of dollars for that particular year.

f(x) = x²

Since g(x) is the translation of the function f(x) and the value of g(x) = 0, when x = -4,

g(x) = (x + 4)²

A cyclic quadrilateral is a quadrilateral which has all its four vertices lying on a circle. The sum of angles in a cyclic quadrilateral is 360 degrees.

Opposite angles of a cyclic quadrilateral is supplementary.

c = 180 - 96

c = 84 degrees

d = 180 - 100

d = 80 degrees

100 = 1 / 2 (a + 99)

0.5a = 50.5

divide both sides by 0.5

a = 50.5 / 0.5
