Answers

Answer:

Step-by-step explanation:

Set up the following ratio. Let the total number of shots = x

40/100 = 140/x Cross multiply

40x = 100* 140 Combine the right

You’d like to see how many baseball and soccer games you can attend this spring. Travel time for basketball games is 2 hours and soccer games is 1 hour. You would like to spend no more than 15 hours traveling to the games. In total, you would like to attend at least 8 games.

Answers

4 basketball games and 7 soccer games

We have to attend 7 basketball games and 1 soccer game.

Given, we had two types of game namely basketball and soccer.

Travel time for basketball games is 2 hours and soccer games is 1 hour.

Let no. of basketball games be x and no of soccer games be y.

According to the question we would like to attend at least 8 games, so we have the inequality [tex]x+y\geq 8[/tex]

And we would spend no more than 15 hours traveling to the game, so [tex]2x+1y\leq 15[/tex].

[tex]x+y=8\\[/tex]

[tex]2x+1y=15\\[/tex]

On solving we get [tex]x=7[/tex] and [tex]y= 1[/tex].

Hence we have to attend 7 basketball games and 1 soccer game.

Answer: -3

So, first off, judging from the h(x) graph, h(x)=-2x–1
So this is compositions or something like that; it’s been a year since I’ve done calculus but here we go:
First, you must find f(6) by replacing every x in that function by 6
f(6) = (1/2)(6) – 4
f(6) = (6/2) – 4
f(6) = 3 – 4
f(6) = -1
Now, since you’ve found f(6), now to find h(-1) (since f is -1 and h( f(6) ) is h(-1) )
h(-1) = 2(-1) – 1
h(-1) = -2 – 1
h(-1) = -3

So, the answer is -3

Hope it helps

Answer: 9

Step-by-step explanation: First, look for the value of x. A number with a variable in front of it means that you’ll be multiplying, but you can use division which makes it easier to find x. SO, DIVIDE 72 by 8 (82 ÷ 7), which equals to 9. (8 x 9 = 72)

The answer is 55. You need to use the rules above to find the actual measure for angle b

Answers

209 + 96 + 55 = 360

Step-by-step explanation:

A circle is 360 degrees

209 is part of the circle so find the difference between 360 and 209

360 - 209 = 151

If the two angles are equivalent to 151, then we find the difference between 151 and 96 to get the measurement for angle b

151 - 96 = 55

A student has passed 60 percent of the 20 quizzes he has written so far successfully. If the student writes 50 quizzes during the year, and passes 80 percent of the remaining quizzes successfully, what would his average percentile be?

Answers

Answer:

A student has passed 60 percent of the 20 quizzes he has written so far successfully mean:

successfully quizzes = 60 % of 20 quizzes = ( 60 / 100 ) * 20 = 60 * 20 / 100 = 1200 / 100 = 12

The remaining quizzes = 50 - 20 = 30 quizzes

80 percent of the remaining quizzes successfully mean:

The remaining successfully quizzes = 80 % of 30 = ( 80 / 100 ) * 30 = 80 * 30 / 100 = 2400 / 100 = 24

Total successfully quizzes = 12 + 24 = 36

Average = ( 36 / 50 ) * 100 % = 0.72 * 100 % = 72 %

Leigh is renting a moving van The function C (d) = 0.12d + 25 is used to relate the cost, C, in dollars of the rental after Leigh
uses the van for d miles. What is the interpretation of the slope for this function? (1 point)
The initial cost of the moving van is $0.12
The additional cost is $25 for each additional mile the van is driven
The initial cost of the moving van is $25.
The additional cost is $0.12 for each additional mile the van is driven

Answers

Answer:

The additional cost is $0.12 for each additional mile the van is driven ⇒ D

Step-by-step explanation:

The form of the linear function is

f(x) = m x + b, where

m is the rate

b is the initial value

In our question

The function C(d) = 0.12 d + 25 represents the cost C in dollars of the rental van uses for d miles

→ Compare it with the form of the linear function above

∴ m = 0.12

∴ b = 25

∵ The cost C depends on the number of miles d

∴ $0.12 is the cost per mile ⇒ additional cost for each additional mile

∴ $25 is the initial cost ⇒ initial cost of the moving the van

The interpretation of the slope for this function is:

The additional cost is $0.12 for each additional mile the van is driven

Answer:

+0.12

Step-by-step explanation:

The additional cost is 0.12 cents for each additional mile the van is being driven.

In a city the distance between the libary and the police station is 3 miles less than than the distance between the police station and fire station the distance between the libary and police station is 5 miles how far apart are the police station and the fire station

Answers

Answer:

8 miles

Step-by-step explanation:

Given

Represent the police station with P, Library with L; Fire station with F

The first statement can be represented as:

[tex]L - P = P - F - 3[/tex]

The second can be represented as:

[tex]L - P = 5[/tex]

Required

Determine the distance between the police station and the fire station (P - F)

[tex]L - P = P - F - 3[/tex] --- (1)

[tex]L - P = 5[/tex] --- (2)

Substitute 5 for L - P in (1)

[tex]5 = P - F - 3[/tex]

Add 3 to both sides

[tex]3 +5 = P - F - 3 + 3[/tex]

[tex]3 +5 = P - F[/tex]

[tex]8= P - F[/tex]

B.) 7 seconds

Step-by-step explanation:

We are given that the ant can crawl 95 centimeters in 5 seconds, which means that it can crawl 19 centimeters in 1 second (95 centimeters/5 seconds). Now you need to divide 19 from 133 (133 centimeters/19 centimeters per second), and you get 7 seconds.

A drone costs $200, and you receive a 15% discount due a coupon. What is
the total amount to be paid?

Answers

Answer:

the total would be 170 dollars

Step-by-step explanation:

200x0.15

Answer:

$170

Step-by-step explanation:

15% of 200 is 30, so subtracting 30 from 200 gets you 170.

If you're having trouble with finding 15% of 200, just flip it around, and find 200% of 15. 15% of 200 and 200% of 15 are both 30. This works no matter what numbers you have. For example, 8% of 100 and 100% of 8 are equivalent, 70% of 200 and 200 and 200% of 70 are equivalent as well.
