Answer:

6.5 km per minute

Step-by-step explanation:

To calculate the average speed, you add the speed of one trip to the speed of the other then divide by 2.

The first trip was a speed of 80km/10 minutes or 8km per 1 minute.

The second trip was a speed of 100km/20 minutes or 5km per 1 minute.

To find the average, add and divide by 2:

$\frac{8+5}{2}=\frac{13}{2}=6.5$ km per minute

At First Class Pizza, 12% of the pizzas made yesterday were pepperoni pizzas. If 27 pizzas have pepperoni, how many pizzas were

gogolik [260]

Answer: 225

Step-by-step explanation:

Let the total number of pizza made be represented by x.

Therefore, the situation in the question can be written as:

12% × x = 27

12/100 × x = 27

0.12 × x = 27

0.12x = 27

Divide both side by 0.12

0.12x/0.12 = 27/0.12

x = 225

The total pizza made was 225.

A table is shaped like a regular hexagon. The length of one side is (7x + 4) in. and the length of another side is (8x − 1) in.

kirza4 [7]

Answer:

39 in.

Step-by-step explanation:

As it's a regular hexagon all sides are congruent.

Therefore

7x + 4 = 8x - 1

4 + 1 = 8x - 7x

x = 5.

So the required length is 7(5) + 4 = 39 in.

A coordinate plane with a line passing through (0, negative 3), (2, 0), and (4, 3).

adell [148]

Answer:

$y=\frac{3}{2}x-3$

Step-by-step explanation:

The given line passes through: (0,-3), (2,0), and (4,3).

We first of all find the slope using $m=\frac{y_2-y_1}{x_2-x_1}$

Using $(x_1=0,y_1=-3),and\:(x_2=2,y_2=0)$ we find the slope to be

$m=\frac{0--3}{2-0}=\frac{3}{2}$

The equation is given by $y=mx+c$ , where $m=\frac{3}{2}$ is the slope and c=-3 is the y-intercept.

Therefore the equation is $y=\frac{3}{2}x-3$
