Answer:

<em>Mario has -16 points.</em>

Step-by-step explanation:

Race car driver Mario won 3 races and earned 75 points for each win.

Total points won = 75\times3=225

During the fourth race he had deductions of 55 points 104 points and 85 points but earned 3 points for finishing.

Total points Mario has now = 225+(-55)+(-104)+(-85)+3

= -16 points

<em>Therefore, Mario has -16 points.</em>

After kicking, one coach likes to play practice games with 6 players on each
Nezavi [6.7K]

There are many possible numbers. First, lets begin with the data there giving us. They are saying she wants to play a practice game so there at least needs to be 2 teams. It also says, that she wants 6 players on each team, nothing more and nothing less. So, for this we are going to use the 6 timetables.

6 x 2 = 12

6 x 3 = 18

6 x 4 = 24

6 x 5 = 30

6 x 6 = 36

There are also more numbers, but I am not doing those. But, for your first five, there can be 12, 18, 24, 30, and 36 students to be on the teams for the practice game.

A Springer Spaniel weighs 20 kilograms 490grams. A Cocker Spaniel weighs 7,590 grams less than a Springer Spaniel. A Newfoundlan
egoroff_w [7]
It is important that the units of measurement for the masses will be expressed in one unit only. For the purpose of illustration in this problem, we express the masses in kilograms. Hence, the mass of Springer Spaniel is equal to 20.49 kg. With this concept, we determine the mass of Cocker Spaniel.

Mass of Cocker Spaniel = 20.49 kg - 7.59 kg = 12.9 kg 

From this calculated mass, we determine the mass of the Newfoundland,
 
Mass of Newfoundland = 12.9 kg + 52.656 kg = 65.556 kg

The difference of the weights of Newfoundland and Springer Spaniel,
   D = 65.556 kg - 20.49 kg = 45.066 kg

<em>ANSWER: 45.066 kg</em>

nevsk [136]

Answer:

13

Step-by-step explanation:

Given:

  1. Square stickers that were 3/4 in long
  2. The spine is 10 and 1/2 in long

If she laid the stickers side by side without gaps or overlaps so the number of sticker to cover the length of the spine:

\frac{The length of the spine}{the length of the sticker}

10 : \frac{3}{4} ≈13  

She needs 13 stickers cover the length of the spine

6. (5 points) Graph using two intercepts; show your work in finding the intercepts. 6x - 3y = 18
Setler [38]

Answer:

Divide both sides by 18. The new coefficients will be the reciprocals of the intercepts:

6x-3y=18 \rightarrow \frac6{18}x - \frac3{18}y = 1 \rightarrow \frac x3-\frac y6 =1 The two intercepts are then 3 and -6.

(I know, dividing by 3 both sides of the equations would have made the whole process way easier).

Alternatively, plug x = 0 to find the y intercept and y=0 to find the x intercept. Either way the graph will look something like the one I'm sketching on paint.

The ratio of marbles to stones in a large pot is 6 to 7. If there are 42 marbles, then how many stones are there?
dexar [7]

Answer:

49 stones

Step-by-step explanation:

Write the following proportion based on the given ratio of marbles (m) to stones (s), and naming the unknown number of stones to find, with the letter "X":

6 m / 7 s = 42 m / X s

cross multiply to get the unknown in the numerator:

6 * X = 42 * 7

divide both sides by 6 to isolate X entirely on the left of the equal sign

X = ( 42 * 7 ) / 6

X = 49

Therefore, there are 49 stones
