Solve for F: C=5/9(F-32) ​

Answer:

Ashleys age is 28.

Step-by-step explanation:

When finding numbers that are consecutive, I like to divide the sum in this case, 100 by the number of people or things, in this case, the 4 siblings. The sum is 100 and there are 4 of them so we divide them first.

100÷4=25 so our answer must be around there. The question states that the ages must be even. So the even numbers in the range of lets say 20-30 are 20, 22, 24, 26, 28 and 30. Closest four numbers to 25 are 22, 24, 26 and 28. We must have two numbers below 25 and two numbers above 25.  So we will keep 22,24,26 and 28. If you add them together, then you'll get 100! Since we are looking for Ashley's age which is the oldest, her age will be 28 as 28 is the highest number out the four numbers (22,24,26,28)

The value of the function f(-4) = 16.

A function is categorized as a relationship between a set of inputs that each have one output.

For the given function in the question;

f(x) = x ² , if  x < 0.

f(x) = 0 , if  x = 0.

f(x) = 2x + 1 , if  x > 0

Now, estimate the values;

(a) f(-4)

As, the value of the x to be substitute is negative, the function used will be.

f(x) = x ² ,for  x < 0.

Put the value x = -4

f(-4) = (-4)²

f(-4) = 16

The value of f(-4) = 16.

(b) f(0)

As the value of function is zero.

Then,

f(x) = 0 , if  x = 0.

Put x = 0 in function we will get.

f(x) = 0.

(c) f(2)

As the value to be substituted is positive, the function used is;

f(x) = 2x + 1 , if  x > 0

Put x = 2

f(2) = 4 + 1

f(2) = 5

Thus, the value of f(2) is 5.

The representation of 1 / 8 in decimal form will be 0.125 and it is a rational number as it is a terminating decimal.

We are given a fraction:

1 / 8.

We have to represent it as a decimal and tell that it is a rational number.

To write it as a decimal, First we will make the denominator a multiple of 10:

1 / 8 × 125 / 125 = 125 / 1000.

Now writing it in the decimal form, we get that:

= 0.125.

Now, we can see that it is a non repeating terminating number.

So, we can say that it is a rational number.

Therefore, the representation of 1 / 8 in decimal form will be 0.125 and it is a rational number as it is a terminating decimal.

Answer:

The correct option is 1.

Step-by-step explanation:

We have to find a function where f(2)=4. It means the value of function is 4 at x=2.

In graph 1, the value of function is 4 at x=2, therefore option 1 is correct.

In graph 2, the value of function is -4 at x=2, therefore option 2 is incorrect.

In graph 3, the value of function is not shown in the graph at x=2, therefore option 3 is incorrect.

In graph 4, the value of function is not shown in the graph at x=2, therefore option 4 is incorrect.

Thus, correct option is 1.

Here are the examples that combine to make zero:

Two month ago, the temperature was 15 degrees. This morning, the temperature dropped to 15 degrees below zero.

Michael has $0 in his account. He makes a purchase of $75. Later in the day, he deposits 75 in the account.

An elevator rises to the ninth floor and she then takes the elevator from the ninth floor to the ground floor.

The parking garage is located 4 floors below ground level. But, her office is 4 floors above ground level.

What are the real world examples?

In order for the examples to combine to make zero, there has to be a positive number and a negative number. A positive number is a number that is greater than zero. A negative number is a number that is less than zero.

In order for the positive and negative number to make zero, they have to be added together. Addition is determining the total value or summing two or more numbers. Addition is one of the four basic operations in mathematics.

Two month ago, the temperature was 15 degrees. This morning, the temperature dropped to 15 degrees below zero. -15 + 15 = 0

Michael has $0 in his account. He makes a purchase of $75. Later in the day, he deposits 75 in the account.  - 75 + 75 = 0

Answer:

277g / 40cm³

Step-by-step explanation:

Density = mass / volume

In this case:

volume = 8cm*5cm*4cm = 160cm³

then:

Density = 1088g / 160cm³ = 544g/80cm³ = 277g/40cm³

Answer:

  156 games

Step-by-step explanation:

You want to know the total number of games when each of 13 teams plays every other team exactly twice.

Each of the 13 teams will meet 12 others, for a total of 13×12 = 156 meetings.

This total counts the time team 1 meets team 2, and also the time team 2 meets team 1. In other words, this is exactly the game count we're looking for.

  156 games will be played.

__

Alternate solution

Team 1 will meet teams 2 through 13, for a total of 12 games. Team 2 has already met team 1, so will need to meet teams 3 through 12 for a total of 11 games. When we count all the games for one meeting between teams, we find the count to be 12 +11 +10 +9 +... +1 = (12)(13)/2 = 78.

If the teams are to meet twice, then 2 times this number of games will be played: 2(78) = 156.

Answer:

The measure of <CDO and <DCo are 60° and 30°.

Step-by-step explanation:

∠CDO = 1/2 ∠CDA

= 1/2 (120)° = 60°

∠ADC + ∠DCB = 180°

120° + ∠DCB = 180°

⇒ ∠DCB = 180° – 120° = 60°

∠DCO = 1/2 ∠DCB

= 1/2 (60°) = 30°

The value of e from the given equation is -1.78

Linear functions are function that has a leading degree of 1

Given the expression below;

0.75(8+e)=2-1.25e

Expand to have;

0.75(8) + 0.75e = 2-1.25e

6 + 0.75e = 2 - 1.5e

6-2 = -1.5e - 0.75e

4 = -2.25e

e = 4/-2.25

e = -1.78

Answer: $0.33 per cup

Step-by-step explanation:

15.84/3 to find the price per 1 gallon.

15.84/3 = 5.28 per gallon

There are 16 cups in a gallon, so divide the price of a single gallon by 16.

5.28/16 = price per cup

5.28/16 = .33

The price for each cup of bleach is $0.33.

The lowest form of this fraction 49/100 is still 49/100.

It should be noted that a fraction can only be reduced to its lowest term if it has a common factor.

In this case, there is no common factor between 49 and 100.

Therefore, the lowest form of this fraction 49/100 is still 49/100

Answer:  Choice 2

invalid. The inner circle is plants, and the outer circle is those with cells.

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

Further Explanation:

If we throw a dart at random, and we land in the inner circle (plants), then we automatically land in the outer circle (has cells).

Now imagine the dart landed in the "has cells" circle, but outside the smaller circle. This could be stuff like animal cells, bacteria, etc. So just because something has cells it does not automatically make it a plant. Saying "an iris has cells" is not enough info to be able to tell it's a plant or not. This means the conclusion of "irises are plants" is shaky at best.

This is why the overall argument structure is invalid.

Answer:

3-11-(-6)

the answer will be

-2

Answer:6 will be greater

Step-by-step explanation:

The graph of the linear equation can be seen in the image below.

Here we have the linear equation:

y = -4x + 8

And we want to find 3 ordered pairs, to do so, we need to evaluate x in different values.

if x = 0 then:

y = -4*0 + 8 = 8

So we have the ordered pair (0, 8).

if x = 1 then:

y = -4*1 + 8 = 4

Then we have the ordered pair (1, 4)

If x = 2 then:

y = -4*2 + 8 = 0

Then we have the ordered pair (2, 0).

Now that we have these 3 ordered pairs, we can graph them in a coordinate axis and then connect them with a line, we will get something like the graph below.

That is the graph of our linear equation:
