Jorge wants to plant 70 total flowers in his new garden.He wants the ratio of tulips to daisies in his garden to be 2 to 5. He d
weeeeeb [17]
Add the ratio together:  2 + 5 = 7
Divide this by the total number of plants;
70/7 = 10

Now times the ration by this number:
2:5 becomes 20:50 (times by 10)
This tells us we have 20 tulips as 50 daisies

A fruit stand has to decide what to charge for their produce. They need \$10$10 for 44 apples and 44 oranges. They also need \$1
KatRina [158]

Answer:

<em>We can't find a unique price for an apple and an orange.</em>

Step-by-step explanation:

Suppose, the price of an apple is x and the price of an orange is y

They need $10 for 4 apples and 4 oranges. So, the first equation will be.......

4x+4y=10 ........................................(1)

They also need $15 for 6 apples and 6 oranges. So, the second equation will be........

6x+6y= 15 ........................................(2)

Dividing equation (1) by 2 on both sides :  2x+2y= 5

Dividing equation (2) by 3 on both sides :  2x+2y=5

So, we can see that both equation (1) and (2) are actually same. That means, we will not get any unique solution for x and y here. Both x and y have <u>"infinitely many solutions"</u>.

Thus, we can't find a unique price for an apple and an orange.

Answer:

The function f(x)= \frac{1}{x^2+2} is continuous for all real numbers

Step-by-step explanation:

To know the possible points of discontinuity of this function, we must find out when the denominator of the function is equal to 0.

The denominator is:

x ^ 2 + 2

Then we equal 0 and clear x

x ^ 2 +2 = 0\\\\x ^ 2 = -2

x ^ 2> 0 for any real number.

This means that

x ^ 2 +2> 0 <em>for all reals numbers</em>.

Therefore, the function f(x)= \frac{1}{x^2+2} is <em>continuous</em> for all real numbers, that is, it does not have discontinuities.

The graphic of this function is shown in the image
