Leah combines 6.54 ounces of strawberries with 6.09 ounces of blueberries to make fruit bowls. She pours the fruit equally into 3 bowls, and has 1.68 ounces of fruit left over. How many ounces of fruit are in each bowl?
Answer:
4.21 Ounces
Step-by-step explanation:
You first want to add 6.54 to 6.09 getting you an answer of 12.63 then you want to divide that by 3 which gets you an answer of: there are 4.21 ounces in each bowl.
Line $1$ represents the graph of $3x + 4y = -14$. Line $2$ passes through the point $(-5,7)$, and is perpendicular to line $1$. If line $2$ represents the graph of $y=mx +b$, then find $m+b$.
Answer:
15
Step-by-step explanation:
First, solve for Line 1
3x + 4y = -14
move the x to the right of the equation
4y = -3x - 14
divide the whole equation by 4
y = -3/4x - 14/4
Line 1 is y = -3/4x - 7/2
Then, solve for Line 2
Since Line 2 is perpendicular, change the sign of the slope of Line 1 and then get the reciprocal of that.
-3/4 to 3/4 to 4/3
4/3 is the slope of Line 2.
Now, we want to find what the b of the equation is, so we can plug in our x (-5) and our y (7) into the y=mx+b equation to find b. The 4/3 is the m or the slope.
y = mx + b
plug in the y, m, and x into the equation
7 = (4/3)(-5) + b
multiply the m and x together
7 = -20/3 + b
add 20/3 to both sides so it will cancel out on the right of the equation and be added to the 7 on the left of the equation
41/3 = b
So, m = 4/3 and b = 41/3
Add them together and you get 45/3 or 15.

Sherry needs to have at least $1600 in her bank account at the end this month. She works at a restaurant where she earns $18 an
hour. This month she has to pay her car payment of $200. How many hours does Sherry need to work to save up enough money.
Answer: 100 hours
Step-by-step explanation:
She has to get a total of 1800 dollars. Since she works 18 dollars an hour, divide 1800 and 18.
1800/18 = 100 hours
QUESTION 1: In Exercises 5–8, use the method illustrated in Example 2 to determine moving averages by subtraction and addition. Determine the 6-day SMA for the ten consecutive trading day closing prices for SunEdison Inc. Listed below. $2.65, $2.63, $2.70, $2.63, $2.50, $2.65, $2.66, $2.56, $2.52, $2.37 * 5 points
Answer:
The 6-day SMA for the ten consecutive trading day
= $2.63, $2.63, $2.62, $2.59, $2.54
Step-by-step explanation:
Determining the 6-day SMA for the given values
using the addition and subtraction methodology
First we will determine the Average closing prices for 1 - 6 days
= [tex]\frac{2.65 + 2.63 + 2.70 + 2.63 + 2.5 + 2.65}{6}[/tex] = 15.76 / 6 = $2.626 ≈ $2.63
next we have to determine the SMA for days 2 - 7
= 2.63 - [tex]\frac{2.65}{6} + \frac{2.66}{6}[/tex] = [tex]\frac{15.77}{6}[/tex] ≈ $2.63
SMA for days 3 - 8
= 2.63 - [tex]\frac{2.63}{6} +\frac{2.56}{6} = \frac{15.70}{6}[/tex] ≈ $2.62
SMA for days 4 - 9
= 2.62 - [tex]\frac{2.70}{6} + \frac{2.52}{6} = \frac{15.52}{6}[/tex] ≈ $2.59
SMA for days 5 - 10
= 2.59 - [tex]\frac{2.63}{6} + \frac{2.37}{6} = \frac{15.26}{6}[/tex] ≈ $2.54
Hence the 6-day SMA for the ten consecutive trading day
= $2.63, $2.63, $2.62, $2.59, $2.54

D=(x2+x1)+(y2-y1) this is the formula I need number 19 Please will mark brainliest and 50 points
Answer:
[tex]2\sqrt{2}[/tex] or [tex]\sqrt{8}\\[/tex]
Step-by-step explanation:
The formula is actually d= [tex]\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}}[/tex]. Now first, we have to find points A and C.
Point A is (1,2) and Point C is (-1,0).
Now we have to substitute the values in. That would make it d =[tex]\sqrt{(-1-1)^{2} + (0-2)^{2}}[/tex].
To simplify the parentheses, it would get to d= [tex]\sqrt{(-2)^{2}+(-2)^{2} }[/tex].
To simplify the exponents, it would get to d = [tex]\sqrt{4+4}[/tex].
To simplify the square root, it would get to d = [tex]\sqrt{8}[/tex].
So the answer is either [tex]2\sqrt{2}[/tex] or [tex]\sqrt{8}\\[/tex].

Hector has $590 in his account. He earned $15 per hour for x hours. Jeremy has $545 in his account. He earned $20 per hour for x hours. They both worked the same number of hours and now have the same amount of money. What is the number of hours that each person worked? Write and solve an equation.
Answer:
equation = 590 + 15x = 545 + 20x
No. of hours worked = 9
Step-by-step explanation:
Given that both worked for same number of hours
and
Jeremy worked for for x hours
it meant that Hector also worked for x hours(it is also mentioned same in the problem)
now that we know the number of hours worked in form of x
lets find
total money in their account if they worked for x hours
___________________________________________
For Hector
Money in Hector's account = $590
Earning for Hector in 1 hour = $15
Earning for Hector in x hour = x*Earning for Hector in 1 hour = $15x
Total money in with Hector after x hours of work
= Money in Hector's account + Earning for Hector in x hour = $590 + $15x
Similarly
For Jeremy
Money in Jeremys account = $545
Earning for Jeremy in 1 hour = $20
Earning for Jeremy in x hour = x*Earning for Jeremy in 1 hour = $20x
Total money in with Jeremy after x hours of work
= Money in Jeremy's account + Earning for Jeremy in x hour = $545 + $20x
Given that they same amount of money
thus
$590 + $15x = $545 + $20x
$sign gets cancelled from both sides
590 + 15x = 545 + 20x Thus, we got the required equation
=> 590 - 545 = 20x - 15x
=> 45 = 5x
=> x = 45/5 = 9
Thus, both of them worked for 9 hours
One pound of apples is $2. You have no more than $13 to spend on apples
Answer:
You are able to by 6 apples with $1.00 dollars remaining.
Step-by-step explanation:
I'm not sure what you were trying to ask because you didn't leave a question in the statement you provided
Answer:
You can buy 6 pounds of apples.
Step-by-step explanation:
13 is an odd number, so we find the closest even number that doesn't go over 13. That number is 12. Then, we take 12 and divide it by 2, since $2 is how much a pound of apples cost. 12 divided by 2 is 6. So, our answer is 6 pounds of apples.

is 104.25 a rational or irrational number
Answer:
Rational
Step-by-step explanation:
Irrational numbers go on forever
The decimal number 104.25 is a rational number.
What is a rational number?If the value of a numerical expression is terminating then they are the rational number then they are called the rational number and if the value of a numerical expression is non-terminating then they are called an irrational number.
The decimal number is the sum of a whole number and part of the fraction number. The fraction number is greater than zero but less than one.
The decimal number is given below.
⇒ 104.25
There are only two-digit after the decimal place which means the number gets terminated.
Then the decimal number 104.25 is a rational number.
