Answer:

0.3

Step-by-step explanation:

0.8/y = 2 : 3/4

The value of y in the above expression can be obtained as follow:

0.8/y = 2 : 3/4

0.8/y = 2 ÷ 3/4

0.8/y = 2 × 4/3

0.8/y = 8/3

Cross multiply

0.8 × 3 = y × 8

2.4 = 8y

Divide both side by the coefficient of y i.e 8

y = 2.4/8

y = 0.3

Thus, the value of y is 0.3

kenny6666 [7]

Answer:

Step-by-step explanation:

6÷2 = 3 and 18÷6 = 3 so: q = 3

$a_n=a_1\cdot q^{n-1}\\\\a_1=2\\q=3\\n=15\\\\a_{15}=2\cdot3^{15-1}\\\\a_{15}=2\cdot3^{14}\\\\a_{15}=9\,565\,938$

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 $50$ .
