If xx and y vary directly and y is 21 when x is 7, find y when x is 5
Answer:
y = 15
Step-by-step explanation:
We need to solve for k
y = x
21 = 7k Divide both sides by 7 to solve for k
3 = k
y = xk
y = 5(3)
y = 15
Answer: y = 15

The question says to simplify it(4x-1)+(-6x+3)
Step-by-step explanation:
(4x - 1) + (-6x + 3)
Combine 4x and -6x to get -2x
-2x + 1 - 3
Subtract 3 from 1 to get -2
-2x - 2
Answer: -2x - 2

A box of greeting cards contains 20 birthday cards, 15 get-well cards, and 15 thank-you cards.
Find the percent of each type of card in the box.
A:20 B:30 C;35 D:40
Answer:
the bday cards are 40%, the get well cards are 30%, and thank you cards are 30%
Step-by-step explanation:
hope it helps :)
Answer:
A: 40%, B: 60%, C: 70%, D: 80%
Step-by-step explanation:
20 + 15 + 15 cards = 50 cards (we are going to use 50 as the denominator)
(multiply the numerator and denominator by 2 for each answer) 20/50 = 40%
30/50 = 60%
35/50 = 70%
40/50 = 80%
For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

You exercise for 34 of an hour. You jump rope for 13 of that time. In simplest form, what fraction of the hour do you spend jumping rope?
Answer:
You spend 1/4 of the hour jumping rope. The question states that 1/3 of 3/4 of an hour is spent jumping rope.
Step-by-step explanation:
Answer: You spend 1/4 of the hour jumping rope.
Step-by-step explanation:
The question states that 1/3 of 3/4 of an hour is spend jumping rope
To find this, multiply 3/4 by 1/3
3/4 times 1/3 = 3/12 = 1/4
So one third of 3/4 is 1/4

Answer:
37.5
Step-by-step explanation:
cosФ = \(\frac{A}{H}\)
cos(33°35') = \(\frac{m}{45}\)
m = 45 × cos(33°35')
m = 37.5 (1d.p.)

To design a spinner with the given probabilities, we can use the following sectors:
A sector covering 60 degrees for the number 1, with probability 1/6.
A sector covering 120 degrees for the number 3, with probability 1/3.
A sector covering 180 degrees for the number 7, with probability 1/2.
A sector covering 180 degrees for the odd numbers (1 and 3), with probability 1.
To create the spinner, draw a circle and divide it into four equal sectors. Color one sector red for the number 1, color two adjacent sectors green for the number 3, color one remaining sector blue for the number 7. Finally, color half of the blue sector green to represent the odd numbers.
The resulting spinner will have the desired probabilities: P(1) = 1/6, P(3) = 1/3, P(7) = 1/2, P(odd number) = 1.
hich equation corresponds to the sentence, "Five times a minus two is equal to t"?

Last month I had 8 guppies. This month I have 20 guppies. What is the percent of increase in guppies from last month to this month?
Answer: 150% increase
Step-by-step explanation:
percent of increase: new/old × 100%-100%
--------------
new/this month: 20 puppies
old/last month: 8 puppies
new/old×100%-100%
=20/8×100%-100%
=2.5×100%-100%
=250% -100%
=150% increase
Hope this helps!! :)

When multiplying or dividing both sides of an inequality by a negative number, the direction of the inequality symbol is flipped. True or false?
Answer:
true
Step-by-step explanation:
Example:
2 > 1 is true.
Now, multiply both sides by -1.
-2 > -1 is false.
To make the inequality true, after multiplying or dividing by a negative number, you must flip the inequality sign.
-2 < -1 is true.

Help Please, I don't understand this
Firstly, you have to understand that if you talk about slope is a similar word gradient of the graph. So if you are calculating slope you have to use gradient formula:
m= Y2-Y1
X2-X1
therefore, in order for you getting first box & second box you have to use this formula above.
First box answer is:
Points fromthegraph (-2:-2) & (-3:-3)
m= Y2-Y1
X2-X1
m = -3-(-2)
-3-(-2)
m = 1
Second box answer is:
Points fromthegraph (3:3) & (4:4)
m= Y2-Y1
X2-X1
m= 4-3
4-3
m= 1
Third box answer is:
= 4
Forth box answer is:
= -3

your friend Shawn tells you that he has been practicing flipping coins so that they will land on heads more frequently than tails. he claims that he can now flip a coin and the probability it will land on heads is 4/3.
do you believe him? why or why not?
Answer:
I wouldn't believe him
Step-by-step explanation:
First of all, how would it land on heads more times than he threw the coin
Second of all, I dont have a friend named Shawn
Third of all, please mark brainliest ;) and have a good day
Answer:
I wouldn't believe him.
Step-by-step explanation:
The reason I won't believe him is that it is a 50/50 chance that it could land or either one and because since there are only two sides. If there were 3 sides, that's another story. You have to look at it since it has 2 sides. It not possible that it is odd and it only two sides.
Hope that helps and makes sense! If not, please let me know and I will edit this :) !
