If paintbrushes cost $1.50 each and canvases cost 6 times that much, which of the following
represents the cost, in dollars, of p paintbrushes and c canvases ?
Answer:
$9 each
Step-by-step explanation:
1.50 x 6 = 9, so c (canvases) are 9 dollars and p (paintbrushes) are 1.50

Answer:
[tex]15x + 30y - 220[/tex]
Step-by-step explanation:
[tex](30 \times \frac{1}{2} x ) + (30 \times - 2) + (40 \times \frac{3}{4} y )+( 40 \times - 4)[/tex]
[tex] = 15x - 60 + 30y - 160[/tex]
[tex] = 15x + 30y - 60 - 160 \\ = 15x + 30y - 220[/tex]
A game of "Doubles-Doubles" is played with two dice. If a player rolls doubles, the player earns 3 points and gets another roll. If the player rolls doubles again, the player earns 9 more points. How many points should the player lose for not rolling doubles in order to make this a fair game?
Answer:
27/35 points
Step-by-step explanation:
The probability of getting one double;
P(getting one double) = 5/36
Probability of getting two doubles is;
P(getting two doubles) = 1/36
Probability of getting no doubles is;
P(getting no doubles) = 1/36
For us to find the Number of points that the player should lose for not rolling doubles, we have;
(12/36) + (5(3 - x)/36) - (5x/6) = 0
(12/36) + (15 - 5x)/36 - 5x/6 = 0
Multiply through by 36 to get;
12 + 15 - 5x - 30x = 0
35x = 27
x = 27/35

Does f(x)=x^2-6x+14 have a minimum or maximum?
Answer:
Step-by-step explanation:
So like uhm its maximum cs I said so period
Answer:
It has a minimum in the point (3, 5)
Step-by-step explanation:
A quadratic function always has either a minimum or a maximum - never both. To find out which one, just look at the coefficient at the x^2. If it's positive, it has a minimum (think of its value for very low x - the value gets higher and higher, because x^2 is positive and rising the lower x is - similar for very high xs when x increases - so it must have a smallest point in the middle).
Analogously, if the coefficient at the x^2 is negative, the reasoning above is reversed - so it has to have a highest point.
Because out function has a positive coefficient at x^2 (the coefficient is 1), we know the function has a minimum.
BTW, let's find the minimum. We can rewrite the function as
[tex]f(x) = x^2 - 6x + 14 = x^2 - 6x + 9 + 5 = (x - 3)^2 + 5[/tex]
Notice that you can do that to any quadratic function by analyzing the ratio between coefficient at x^2 and at x.
Now the function is an x^2 function that was moved 5 upwards and 3 to the right. The minimum has to be in x - 3 = 0, so x = 3, and the value is 5!
The minimum is at (3, 5).
x= -3 and x = 7

Madison is saving for a new flat screen TV, which cost $600. She has already saved $25. She earns $50 per week working at the supermarket. How many weeks will it take to earn enough for the new flat screen TV? b) Write an equation showing the relationship between the number of weeks and total savings.
please help!
Answer:
$50w + 25 = $600 12 weeks
Step-by-step explanation:
replace w with 12.
(50 x 12) + 25 = 625
so that means she has to work 12 weeks to get the minimum amount needed

Step-by-step explanation:
Quinn had $4.00. He spent 1/2 of his money on a baseball card, 1/4 of it on a drink, and 1/8 of it on bubble gum. How much money does Quinn have left?
US dollars btw
Answer:
$0.50
Step-by-step explanation:
He spent 2 on a card 1 on a drink and 1/2 on a piece of gum.
4 - (2+1+1/2) = 1/2
I am not sure it's correct.
Answer: Quinn has $0.50 left.
Step-by-step explanation:
This is because if you were to divide $4.00 into 1/2 it would equal $2.
Next, you would divide $4 into 1/4, this would give you $1.
Finally, you would divide $4 into 1/8, this would give you $0.50.
To get the answer you would add all of those quotients together, adding up to $3.50.
You would then take $4.00 - $3.50 = $0.50
(To get those numbers just divide by the denominator it is way easier. Example: To divide $4 into 1/8 you would divide by 8. aka 4 ÷ 8.)
Need Help With This Problem
Can someone help me with this problem? Plzzzz
ASAP!!!
Answer:
b=70 degrees
Step-by-step explanation:
a= 8x+6. b= 4x+38
a=b alternate exterior
combine like terms
8x+6=4x+38
Subtract 4x from both sides and 6
4x=32
Divide by 4
x=8
Plug in= 8 for B equation
b= 4(8)+38
b=70 degrees
Answer:
x = 8
m∠B = 70°
Step-by-step explanation:
The alternate exterior angles theorem states that m∠A and m∠B are the same. So,
8x + 6 = 4x + 38
Subtract 6 from both sides.
8x = 4x + 32
Subtract 4x from both sides.
4x = 32
Divide both sides by 4.
x = 8
Now to find the measure of m∠B, substitute x = 32 into 4x + 38.
8 * 4 + 38 =
32+ 38 = 70
m∠B = 70°
Just in case, let's double check our answer. Because m∠A is equal to m∠B, m∠A should be equal to 70.
70 = 8x + 6
70 = 8 * 8 + 6
70 = 64 + 6
70 = 70
Thus, x = 8 and m∠B = 70° is true.
I hope this helps! Feel free to ask any questions!

You roll a 6-sided die.
What is P(5)?
Write your answer as a fraction or whole number.
Answer:
1/6
Step-by-step explanation:
there is one 5 on the die. therefore the chance of rolling a 5 is 1/6
The required probability P(5) = 1/6.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
+ Addition operation : Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation : Subtracts right hand operand from left hand operand.
for example 4 -2 = 2
* Multiplication operation : Multiplies values on either side of the operator
For example 4*2 = 8
The die has only one 5 on it.
The number of favorable outcomes = 1
There are the total outcomes as {1, 2, 3, 4, 5, 6}
So the total number of outcomes = 6
Required probability P(5) = 1/6
Hence, the chance of rolling a 5 is 1/6
