Answer:
Part A: x÷3=$499
Part B: $1497
Step-by-step explanation:
A: Because to find a fraction of somthing we have to divide, so in this case we divided the original price by 3 to get $499.
B:To find the original price we have to multiply the one third of it ($499) by 3 to get the original amount.

Answer:
the square of -5 is 25 not -25
, -4(1)(-3) is 12 not -12 because when we multiply 2 negative numbers their result is positive
+5 should be written instead of -5
Step-by-step explanation:
+5 should be written instead of -5 as the formula is (-b+-(b²-4ac)½)/2a . since b=-5 ;-b=+5
Point Q was rotated about the origin (0,0) by -45 degrees
Answer:
0,0
Step-by-step explanation:
The point Q was rotated about the origin (0,0) by -45 degrees, so the new coordinate point is (√2, 4√2).
From the given graph, the coordinates of point Q are (-3, 5).
Rotating the co-ordinate axes through an angle of 45° in anti-clockwise direction is equivalent to rotating the point through an angle of -45° about origin.We will use rotation from complex numbers to solve this.
Let x + iy the new complex number
(-3+5i)[tex]e^{\frac{-\pi i}{4} }[/tex]
= (-3+5i)((1-i)/√2)
= (-3+5i)(1-i) ×1/√2
= (-3+5i+3i-5i²) ×1/√2
= (-3+8i+5) ×1/√2
= (2+8i) ×1/√2
= (2/√2 + 8i/√2)
= (√2 + 4√2i)
So, the coordinates are (√2, 4√2)
Therefore, the point Q was rotated about the origin (0,0) by -45 degrees, so the new coordinate point is (√2, 4√2).

What is the largest possible integral value in the domain of the real-valued function
f(x)=[tex]\frac{1}{\sqrt{800-2x} }[/tex]

Step 1: Define
[tex]f(x) = \frac{1}{\sqrt{800-2x} }[/tex]
Step 2: Identify Variables
Using U-Substitution, we set variables in order to integrate.

We know from a real number line that we cannot have imaginary numbers. Therefore, we cannot have any negatives under the square root.
Our domain for our integrated function would then have to be (-∞, 400]. Anything past 400 would give us an imaginary number.
A bag contains five ping-pong balls numbered 1 to 5. Two balls are removed to form a two digit number. The smallest possible number is 12 and the largest is 54. What is the probability that the number formed is prime? (hint: Write out the entire sample space)
Answer:
[tex]\frac{11}{42}[/tex] or 26.19%
Step-by-step explanation:
If the range of possible numbers is between 12 and 54 then that means that there are 42 (54 - 12) possible numbers that can be made. In this range, there are 11 prime numbers which are the following...
13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53
Therefore, the probability that the number formed is a prime would be [tex]\frac{11}{42}[/tex] which if we divide and multiply the decimal by 100 we get the probability in percentage form.
[tex]\frac{11}{42}[/tex] = 0.2619
0.2619 * 100 = 26.19%
Finally, we can see that the probability of this happening is 26.19%
Does the line whose equation is y=-2x+13 pass through the point (4,5)? Explain how you arrived at
your answer.
Answer:
Yes
Step-by-step explanation:
Plug in 4 for x, 5 for y. if it equals, then its a point
5 = -2(4) + 13
5 = -8 + 13
5 = 5
it equals so (4,5) is a point
An oil drilling company drills the same distance each day for 5 days. They started at an elevation of 121.175 feet and ended at an elevation of -246.875 feet. Which equation can be used to find x, the distance they drilled each day?
Answer:
[tex]x=\dfrac{|-246.875-121.175|}{5}[/tex]
Step-by-step explanation:
Given that:
Same distance is drilled by the oil drilling company for 5 days.
Initial elevation = 121.175 feet
Final elevation = -246.875 feet
To find:
The equation to find the value of [tex]x[/tex] i.e. the distance drilled each day?
Solution:
To find the distance drilled each day, we need to divide the total distance drilled with the number of days taken to drill the total distance.
Total distance drilled can be found by subtracting the initial elevation from the final elevation and taking modulus because distance can not be negative.
Total distance drilled = | Final elevation - Initial elevation |
Total distance drilled = | -246.875 - 121.175 |
Therefore, we can write the expression as:
[tex]x=\dfrac{|-246.875-121.175|}{5}[/tex]
[tex]\Rightarrow x=\dfrac{|-368.05 |}{5} =73.61\ ft/day[/tex]

Answer:
x = 4.5
Step-by-step explanation:
Let's solve this together!
First you would want to multiply 6 and x:
6×2 = 12
x×2 = 2x
Then you would want to subtract 12 from 3:
3+12 = 9
Then divide 9 by 2:
9÷2 = 4.5
x=4.5
That's it!

8.25+0.25w=10.75
0.25w=10.75-8.25
0.25w=2.5
w=10

Use the dot product to find v when v=(-2 -1)
a. -1 c. √5
b. -3 d. √3
Since you're only given the one vector, I assume you're supposed to find the magnitude of v, or ||v||, using the dot product.
We have
v • v = (-2, -1) • (-2, -1) = (-2)² + (-1)² = 5
so that
||v|| = √(v • v) = √(5)
and the answer is C.
Answer:
C

Answer:

Step-by-step explanation:
So If this tells you what 'm' and 'n' are, you just put them inside.
First do the M so then it will be 5 * 10 which is 50 then we just first leave it there. Then we start putting in that N. We know that N is 4. Then it's N to the power of 2. I recommend since there's already a 4 on the bottom, just do 4 * 4 there. Then you see there is a 4 on the denominator while there are double 4's on the numerator. Then you just cross one 4 on the denominator and one on the numerator to simplify it.
Then all there is is 50 + 4 = 54
So 54 is our answer.

Step-by-step explanation:
10m + n^2/4 (m=5 , n=4)
(10*5) + (4^2/4) =

Shane and Gemma share 35 sweets in the ratio 1:4
1
Gemma eats 10 of her sweets and then gives Shane 2 of the sweets she has left.
(c) How many sweets does Shane have now?
Answer:
Shane has 9 sweats now.
Step-by-step explanation:
Given that Shane and Gemma share 35 sweets in the ratio 1:4.
Let the share of Shane be = 'x'
Let the share of Gemma be = '4x'
The combined share of Shane and Gemma = x + 4x = 5x
Total sweets they share = 35
so the equation becomes
5x = 35
x = 7
Thus,
Share of Shane = x = 7
Share of Gemma = 4x = 4(7) = 28
Gemma eats 10 sweets, so she has left with 28-10 = 18 sweets
Gemma gave 2 of the sweets she has left.
As Shane has already 7 sweats, so adding 2 in 7 sweats would make it 9 sweats.
Therefore, Shane has 9 sweats now.
Is the relation a function? If it is a function, state the domain and range. If not, circle or
highlight the part that causes it to not be a function.
Answer:
Please check the explanation.
Step-by-step explanation:
Writing this relation in set notation using curly braces:
{(1, 3), (2, 5), (3, -1), (4, 0), (5, 6)}
The relation clearly indicates that each input is related to exactly one output. In other words, there is no repetition of 'x' values.
Hence, this relation is a function.
We know that the domain is the set of all x values.
Thus, the domain is: {1, 2, 3, 4, 5}
We know that the domain is the set of all y values.
Thus, the range is: {-1, 0, 3, 5, 6}

hanna can wrap 10 boxes 30 minutes. how many boxes can she wrap in 60 minutes
Answer:
20
Step-by-step explanation:
Answer:
She would have wrapped 20 boxes.
Step-by-step explanation:
You would look at how many boxes she can wrap in 30 mins which is 10. 60 divided by 30 is 2 so you would take 10 and multiply it by 2 to get 20.
