-f=-100<br> solve for f<br> f=<br> wold the answer be 1
marshall27 [118]
1 is incorrect. to solve for f, you have to get it alone, and right now you have a negative sign in your way.

you can eliminate the negative by dividing both sides by -1:

-f = -100

divide by -1 to cancel out the - in front of f

f = 100

Let the graph of f(x) represent the cost in thousands of dollars to feed the zoo animals daily, where x is the number of animals
pickupchik [31]

Answer:

<u>There are 200 animals, and the cost is $8,000 daily</u>

Step-by-step explanation:

y=f(x) represents the cost in thousands

x is the number of animals measured in hundreds

so the point (2,8) means

x = 2

y = f(2) = 8

so it means  for 2*100=200 animals, the cost is 8*1000=8 000

The correct answer is then

There are 200 animals, and the cost is $8,000 daily

hope this helps

What are the values of a and b?
ivann1987 [24]

Answer:

<h2>a = 400/21, b = 580/21</h2>

Step-by-step explanation:

Small triangles are similar. Therefore, the sides are proportional

\dfrac{a}{20}=\dfrac{20}{21}               <em>cross multiply</em>

21a=(20)(20)       <em>divide both sides by 21</em>

a=\dfrac{400}{21}

For b, we can use the Pythagorean theorem:

b^2=\left(\dfrac{400}{21}\right)^2+20^2\\\\b^2=\dfrac{160000}{441}+400\\\\b^2=\dfrac{160000}{441}+\dfrac{176400}{441}\\\\b^2=\dfrac{336400}{441}\to b=\sqrt{\dfrac{336400}{441}}\\\\b=\dfrac{\sqrt{336400}}{\sqrt{441}}\\\\b=\dfrac{580}{21}

What is the value of 5 2/3(−3.6)?
Anestetic [448]

Answer:

<em>Hello, Your answer will be -20 2/4.</em>

Step-by-step explanation:

Conversion a mixed number 5 2

3

to a improper fraction: 5 2/3 = 5 2

3

= 5 · 3 + 2

3

= 15 + 2

3

= 17

3

To find new numerator:

a) Multiply the whole number 5 by the denominator 3. Whole number 5 equally 5 * 3

3

= 15

3

b) Add the answer from previous step 15 to the numerator 2. New numerator is 15 + 2 = 17

c) Write previous answer (new numerator 17) over the denominator 3.

Five and two thirds is seventeen thirds

Conversion a decimal number to a fraction: -3.6 = -36

10

= -18

5

a) Write down the decimal -3.6 divided by 1: -3.6 = -3.6

1

b) Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)

-3.6

1

= -36

10

Note: -36

10

is called a decimal fraction.

c) Simplify and reduce the fraction

-36

10

= -18 * 2

5 * 2

= -18 * 2

5 * 2

= -18

5

Multiple: 17

3

* (-3.6) = 17 · (-18)

3 · 5

= -306

15

= -102 · 3

5 · 3

= -102

5

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(-306, 15) = 3. In the next intermediate step the fraction result cannot be further simplified by cancelling.

In words - seventeen thirds multiplied by minus eighteen fifths = minus one hundred two fifths. <em>Hope That Helps!</em>
