The attendant at a parking lot compared the number of hybrid vehicles to the total number of vehicles in the lot over a weekend.

EastWind [94]

We are given:

The ratios of the number of hybrid vehicles to the total number of vehicles in the lot over a weekend (3 days) are equivalent.

This means that if on day 1, 100 hybrid cars parked and there are 300 cars in total, the ratio is 1 is to 3.

Therefore, on day 2 and 3, we can determine the number of hybrid cars parked given the total number of cars parked using the ratio, and vice versa.

Describe and correct the error a student made in writing an exponential function

NemiM [27]

Answer:

we CANNOT DIVIDE 3 with 6.

Step-by-step explanation:

Here,as given in the question:

Starting value = 6

Constant ratio = 1/3

Now, exponential function is obtained by the product of starting value and the constant ratio repeatedly.

⇒ f(x) = (Starting value) x (ratio)... x times

$\implies f(x) = 6 (\frac{1}{3} )^x = 6 (\frac{1}{3} ) (\frac{1}{3} ) (\frac{1}{3} ) .... x$

Now, we CANNOT DIVIDE 3 with 6 as it is in the power of x.

Hence, $\implies f(x) = 6 (\frac{1}{3} )^x$ and $f(x) \neq 2^x$

nadezda [96]

Answer: 12,8 approximately 13 cones

Step-by-step explanation:

1] volume of a cone

V=1/3πr^2h

V=1/3π(3)^2(5)

V=47,12 cubic inches

2] volume of a cylinder

V=πr^2h

V=π(8)^2(3)

V=603.19

Now devide the volume of a cylinder by the volume of a cone

603,19÷47,12=12,8 cones

Write the equation - 3x + 2y = 7 in slope-intercept form.

VikaD [51]

Answer:

The answer is :

$y = \frac{3}{2} x + \frac{7}{2}$

Step-by-step explanation:

Given that the slope-intercept form is represented by y = mx + b. So you have to rearrange the equation :

$- 3x + 2y = 7$

$2y = 3x + 7$

$y = \frac{3}{2} x + \frac{7}{2}$
