Race car driver mario won 3 races and earned 75 points for each win. During the fourth race he had deductions of 55 points 104 points and 85 points but earned 3 points for finishing. Write and find the value of an expression for how many points he has now

Answers

Answer:

Mario has -16 points.

Step-by-step explanation:

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

Total points won = $75*3=225$

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

Therefore, Mario has -16 points.

Answer:

(75 * 3) + 55 + 104 + 85 + 3.

75 * 3, because each race is 75 points.

8. The temperature was 8°F. It dropped so that the temperature was 0°F.°F represents the change in temperature.

Answers

Answer: -8f

Initial temperature= 8F
Final temperature = 0F

Change temperature= Final temperature-initial temperature

Change in temperature = 0-8F
Change temperature = -8F
So final answer is
change in temperature = -8F

If the ratio of boys to girls at the school is 2:5 and there are 40 boys how many girls are there?

Answers

The total number of students in school is 140 and number of girls at the school is equal to 100.

What do you mean by ratio ?

Ratio is the quantitative relationship between two values indicating how frequently one value contains or is contained within the other.

It is given that the ratio of boys to girls at the school is 2:5.

Let's assume the total number of students in school is x.

We now need to find the number of girls in the school but before that we must try to find the total number of students in the school.

Sum of ratios = 2 + 5 = 7

It is given that there are 40 boys in students.

2/7 of the total number of students are boys.

i.e., the expression can be written as :

2x / 7 = 40

2x = 40 × 7

2x = 280

x = 140

The total number of students in school is 140.

So , the number of girls in school is :

= 140 - 40

= 100

There are 100 girls in the school.

Therefore , the total number of students in school is 140 and number of girls at the school is equal to 100.

Answer:

100 girls

Step-by-step explanation:

The ratio of boys : girls is 2 : 5.

In other words, boys are 2 parts of the school while girls are 5 parts of the school.

Since there are 40 boys, 2 parts of the school is 40. Thus:

$2p = 40\np = 20$

1 part is 20.

Since there are 5 parts girls, there are

$5p = 5*20 = 100$

100 girls.

Answer: 100 girls

Which function has the largest maximum?

Answers:
f(x)
g(x)
h(x)
All three functions have the same maximum value.

Answers

Answer:

The correct option is 1. The function f(x) has the largest maximum.

Step-by-step explanation:

The vertex form of a parabola is

$y=a(x-h)^2+k$

Where, (h,k) is vertex.

The given functions is

$h(x)=-(x-5)^2+3$

Here, a=-1, h=-5 and k=3. Since the value of a is negative, therefore it is an downward parabola and vertex is the point of maxima.

Thus the maximum value of the function h(x) is 3.

$g(x)=4\cos (2x-\pi)-2$

The value of cosine function lies between -1 to 1.

$-1\leq \cos (2x-\pi)\leq 1$

Multiply 4 on each side.

$-4\leq 4\cos (2x-\pi)\leq 4$

Subtract 2 from each side.

$-4-2\leq 4\cos (2x-\pi)-2\leq 4-2$

$-6\leq 4\cos (2x-\pi)-2\leq 2$

Therefore the maximum value of the function g(x) is 2.

From the given table it is clear that the maximum value of the function f(x) is 4 at x=3.

Since the function f(x) has the largest maximum, therefore the correct option is 1.

Max(f(x)) = f(3) = 4

Max(g(x)) = g(π/2) = 2

Max(h(x)) = h(5) = 3

Of these values, f(3) = 4 is the largest.

The function with the largest maximum is f(x).
