What grade is this? !

Combine the constants into one:

n^2 + 88 = 0

This has two complex roots.

I suspect you may have meant n^2 + 10n + 78 = 0.

Double check the original problem and make any necessary corrections.

4: 0.99

5: 0.66

6: 0.79

7: 5.2

8: 4.86

9: 4.3

I hope I helped! Also, one thing when you adding decimals or multiplying them, pretend the decimal point isn't even there. Then, once you have your answer, you just add the decimal in the middle. Basically just adding like in first grade! Super easy and I hope I helped!

The graph shows how many apples Erin can pick if she maintains a constant rate. What is the linear equation for this relationshi

Ainat [17]

Answer:

The linear equation $y=50(x)$ and Erin can pick $50$ apples per hour if she maintains a constant rate.

Step-by-step explanation:

To find the linear equation of the relationship from the graph.

We have to find the coordinates .

Let say $(x,y)=(1,50)$ and $(x_1,y_1)=(2,100)$

Here $x$ variable is the time in hour and $y$ variable is the number of apples.

To find linear equation we have to find the slope (m) of the line by using point-slope form.

$m=\frac{y_1-y}{x_1-x}$

So,

$m=\frac{100-50}{2-1}=50$

The the linear equation will be.

$y=50(x)$

Number of apples Eric pick in an hour is $50$ .

By plugging the value of $x=1$ in the equation we can find the number of apples picked by Erin per hours subsequently $x=2$ for second hour.

In each hour she picks $50$ apples.

Linear equation is $y=50(x)$ and number of apples picked by Eric in an hour is $50$ .

Find a ratio equivalent to 15/60

Flauer [41]

Answer:

$\large\boxed{\dfrac{15}{60}=\dfrac{5}{20}=\dfrac{3}{12}=\dfrac{1}{4}}$

$\large\boxed{\dfrac{15}{60}=\dfrac{30}{120}=\dfrac{45}{180}=\dfrac{60}{240}}$

Step-by-step explanation:

Divide the numerator and the denominator by the same number:

$\dfrac{15}{60}\\\\=\dfrac{15:5}{60:5}=\dfrac{3}{12}\\\\=\dfrac{15:3}{60:3}=\dfrac{5}{20}\\\\=\dfrac{15:15}{60:15}=\dfrac{1}{4}\\\vdots$

Multiply the numerator and the denominator by the same number:

$\dfrac{15}{60}\\\\=\dfrac{15\cdot2}{60\cdot2}=\dfrac{30}{120}\\\\=\dfrac{15\cdot3}{60\cdot3}=\dfrac{45}{180}\\\\=\dfrac{15\cdot4}{60\cdot4}=\dfrac{60}{240}\\\vdots$
