Answer:
9.1 or 10 weeks
Step-by-step explanation:
First you need to create an equation: 150 + 45w = 560
You need to get the w by itself. To do this we need to take 150 from both sides: 150 (-150) + 45w = 560 (-150)
45w = 410
Now we have to divide both sides by 45:
w = 9.1
So it took Briyana just over 9 weeks to save $560 for spring break
I hope this helps
Let's work this out using the inequality it suggests.
We can use the form [tex]y=mx+b[/tex], but have the equals sign substitute out for whatever sign we need.
When you need to buy something, do you need to have more, less, or the same amount of money to buy something?
You need to have at least the same amount of money.
Which means that we'll be using the ≥ sign.
[tex]y\geq mw+b[/tex]
Now let's substitute in some values we know.
She has 150 to start off with, think of this as the y-intercept of the graph.
What variable represents the y-intercept?
You should've said b.
[tex]y\geq mw+150[/tex]
Now how much is she saving her week? $45.
Since this is how much she's saving every week, this represents the slope.
[tex]y\geq 45w+150[/tex]
Now, we can solve this plugging in 560 for [tex]y[/tex], which is how much money she needs.
[tex]560\geq 45x+150[/tex]
[tex]410\geq 45w[/tex]
[tex]\frac{82}{9}\geq w[/tex]
[tex]\frac{82}{9}[/tex] is 9.111 (repeating), but we need to round up to the nearest whole number because she probably doesn't deposit money constantly during the week, and rather all at once.
Which means that she needs to save money for 10 weeks to have enough money for the spring break trip.
Hope this helps.
頑張って!
Find the simplified product:[tex]\sqrt{2x^{3} }-\sqrt{18x^{5} }[/tex]
Correct Question: Find the simplified product: [tex] \sqrt{2x^3}*\sqrt{18x^5} [/tex]
Answer:
[tex] 6x^4 [/tex]
Step-by-step explanation:
Based on the rules of radicals, since [tex] \sqrt{2x^3} [/tex] and [tex] \sqrt{18x^5} [/tex] has the same index (square root), therefore:
[tex] \sqrt{2x^3}*\sqrt{18x^5} = \sqrt{2x^3 * 18x^5} [/tex]
To simplify this, multiply their bases together, and add their exponents.
[tex] = \sqrt{2*18x^{3+5} [/tex]
[tex] = \sqrt{36x^{8} [/tex]
Simplify further
[tex] = \sqrt{36}*\sqrt{x^8} [/tex]
[tex] = \sqrt{6*6}*\sqrt{x^4*x^4} [/tex]
[tex] = 6x^4 [/tex]

A sock drawer contains 5 different colors of socks. It has 20 white, 10 black, 10 gray, 6 red, and 4 purple. If you reach into the drawer and choose a sock randomly, what is the probability you will get a black sock? P (black) = StartFraction Number of favorable outcomes over Total number of outcomes EndFraction P(black) =
Answer:
1/5
Step-by-step explanation:
Total number of socks = 50( 20+10+10+6+4)
Number of black socks = 10
Therefore, 10/50= 1/5
the probability of getting a black sock is 1/5.

Explain why the graph of the equation g(x) = -(x + 1 ) - 3 would be a parabola opening downward.
Answer: Because the a-value is negative.
Step-by-step explanation:
The vertex form of a quadratic equation is: y = a(x - h)² + k where
"a" is the vertical stretch-a is a reflection over the x-axish is the horizontal shift (positive = right, negative = left)k is the vertical shift (positive = up, negative = down)Given: g(x) = - (x + 1)² - 3
↓
a= -1
Since the a-value is negative, the parabola will be reflected over the x-axis which will change the curve from (U-shaped) to (∩-shaped).
In a class of 50 statistics students, 27
students received an A. What fraction of the class received an A?
Answer:
Fraction of the number that received an A= = 27/50
Step-by-step explanation:
In a class of 50 statistics students, 27
students received an A.
Total number of students=50
Number that received an A= 27
Fraction of the number that received an A= Number that received an A/Total number of students
Fraction of the number that received an A= = 27/50
On a map, 2.5 inches represents 300 miles. How many miles are represented by 6 inches?
А .05 miles
00
.40 miles
С
600 miles
D
720 miles
Answer:
D. 720 miles
Step-by-step explanation:
First, we know that 2.5 inches represents 300 miles. This means that we have to find out how much 1 inch represents in miles. So, we take 300/2.5. This results in 120. So, 1 inch represents 120 miles. Then, we take 6*120 which gets us 720 miles.
A map of 720 miles represented by 6 inches.
It is given that 2.5 inches represent 300 miles.
It is required to find the miles represented by 6 inches.
How many miles are represented by 6 inches?First we have to find how many miles we get in one inch. Then we find in how many miles does 6 inches have.
In 2.5 inches, the map represents 300 miles.
In 1 inch, a map represents 300/2.5 miles which are equal to 120 miles.
So, in 6 inches, a map represents (120×6) miles which are equal to 720 miles.
Thus in 6 inches, a map represents (120×6) miles which are equal to 720 miles.

Steps to solve:
6a + 12 = 3(2a + 1) + 5
~Distribute right sides
6a + 12 = 6a + 3 + 5
~Simplify
6a + 12 = 6a + 8
~Subtract 12 to both sides
6a = 6a - 4
~Subtract 6a to both sides
0 = 4
Therefore, there are no solutions.

(-2ab^-5)(4a^-2b)^-2
Answer:
-a^5/(8b^7)
Step-by-step explanation:

ANSWER AS SOON AS POSSIBLE PLEASE! Jessica has $19. She buys 4 apples for x dollars each. Levi has $30 and buys 7 apples for x dollars each. Write an expression of how much money altogether they would have left?
This is the same as -11x+49
=========================================================
Explanation:
1 apple = x dollars
4 apples = 4x dollars, after multiplying both sides by 4
If Jessica buys 4 apples, then she spends 4x dollars.
Jessica has $19, so she'll have 19-4x dollars leftover after buying those four apples.
Similarly, Levi will have 30-7x dollars leftover when buying 7 apples for x dollars each.
Add up the leftover amounts to get...
(jessica's leftovers) + (Levi's leftovers)
(19-4x)+(30-7x)
19-4x+30-7x
(19+30)+(-4x-7x)
49-11x
This is the same as -11x+49 since you can think of 49-11x as 49+(-11x), and we can add two terms in any order we want.
---------------------------
An alternative viewpoint
Pool up Jessica's and Levi's amount they start with to get 19+30 = 49 dollars
Jessica buys 4 apples and Levi buys 7 apples. In total, this is 4+7 = 11 apples. At x dollars an apple, they spend 11x dollars. So they'll have 49-11x dollars leftover after buying those 11 apples.

A high school basketball team won 36% of the games that it played last season. The team won exactly 9 games last season. What is the total number of games that the team played?
Answer: REMEMBER TO RATE 5 STARS AND GIVE ME A HEART, THANKS!!!
The High Shcool Basketball team played a total of 25 games.
Step-by-step explanation:
You take the 9 from the games they won last season and divide it by .36 and that will give you the answer of 25. So 25 is the total games the "High School Basketball Team" won. If you want to double check your answer you can take the answer of 25 and times it by .36 which will equal 9.

To write a fraction as a decimal, you simply divide the numerator by the denominator.

What are two things we look for in an equation that can tell us what's NOT in it's domain?
Answer:
1. Value for which denominator is 0.
2. Value for which we get negative sing inside the root or log.
Step-by-step explanation:
Domain is the set of input values.
If a function is not defined for a set of value then they are NOT in it's domain.
Two we look for in an equation that can tell us what's NOT in it's domain :
1. Value for which denominator is 0.
2. Value for which radicand is negative because negative values inside the square roots are not real. Value for which log values are negative because log is not defined for negative values.
