Given:
Selling price (S.P.)= $4,600
Cost price (C.P.)= $4,000
To find:
The profit percentage.
Solution:
Formula used:
[tex]\text{Profit}\%=\dfrac{S.P.-C.P.}{C.P.}\times 100[/tex]
Using this formula, we get
[tex]\text{Profit}\%=\dfrac{4600-4000}{4000}\times 100[/tex]
[tex]\text{Profit}\%=\dfrac{600}{40}[/tex]
[tex]\text{Profit}\%=15[/tex]
Therefore, the profit percentage is 15%.

What is the value for X?
Answer:
5
Step-by-step explanation:
6x + 4 + 73 + 73 = 180
6x + 150 = 180
6x = 30
x = 5
Those little marks on AB and BC denote congruence. That makes the triangle isoceles. That means the base angles are equal. Both 73.
Triangle Sum Theory states all angles of a triangle add to 180.

a man in a boat rowing from light house whose height is 200 meter.he takes 2minutes to change the angle of elevation top of light house from 60⁰ and 45⁰ find speed of boat
Answer:
The speed of the boat is approximately 0.704 m/s
Step-by-step explanation:
The time it takes the man in the boat to change the angle of elevation from 60° to 45°, t = 2 minutes = 120 seconds
The height of the light house = 200 m
Given that the angle of elevation is reducing, the direction of the man is away from the lighthouse
The initial distance of the man in the boat from the lighthouse = 200 m/(tan(60°)) = (200/√3) m
The final distance of the man in the boat from the lighthouse = 200 m/(tan(45°)) = 200 m
The distance traveled in 2 minutes, d = 200 m - (200/√3) m ≈ 84.53 m
The speed of the boat, v = d/t
∴ v = 84.53 m/(2 min × 60 s/min) ≈ 0.704 m/s
The speed of the boat, v ≈ 0.704 m/s.
which two ratios represent quantities that are proportional help i will mark as brainless
Answer:
A
Step-by-step explanation:
So, lets take all of our ratios, and simplfy them the best we can. Once we do this, we can easily compare and see which ratios are and are not similar.
So lets start with A:
21/28 and 12/16
Lets simplfy each fraction.
The greatest number that goes into the numeraotr and denominator(GCF) of 21/27 is 7. Taking out 7 we get:
3/4
We can do the same with the 12/16. 4 goes into both the numerator and denominator:
3/4
So this would work.
Lets look at the others, and see if any others work as well:
56/64 and 36/48
8 goes into both 56 and 64:
7/8
4 goes into 36 and 48:
9/12
These are clearly different.
Next we have 9/10 and 10/9
We can instantly see that one is bigger than 1, and the other is smaller than 1, so they must be different.
Finally we have 5/7 and 7/14
Again, these are clearly different.
If we give both the same denominator, which can be 14, we get:
10/14 and 7/14
We get 10/14 from 5/7 since we need to multiply both numerator and denominator by 2 so that the 7 becomes 14 in the denominator.
10/14 adn 7/14 are clearly different, so these dont work as well.
Only A, which is 21/28 and 12/16, will work.
Hope this helps!

Two containers designed to hold water are side by side, both in the shape of a
cylinder. Container A has a radius of 12 feet and a height of 15 feet. Container B has a
radius of 8 feet and a height of 17 feet. Container A is full of water and the water is
pumped into Container B until Containter B is completely full.
To the nearest tenth, what is the percent of Container A that is full after the pumping
is complete?
play
play
A
Container B
Answer:
49.6% of container A is still full
Step-by-step explanation:
volume of a cylinder : pi×r²×h
Va = pi × 12² × 15 = pi×144×15 = 6785.84013... ft³
Vb = pi × 8² × 17 = pi×64×17 = 3418.05281... ft³
how much of A is still filled, when B has been completely filled ?
Va left = Va - Vb = 3367.78732... ft³
100% of Va = 6785.84013... ft³
1% of Va = 67.8584013... ft³
so, how often does 1% of Va fit into the remaining filing volume of A (Va left) ?
3367.78732... / 67.8584013... = 49.6(2962963...)%
Consider the algebraic expression:

Which of the following is a constant in this expression?
Which of the following lists all the coefficients in this expression?
Answer:
constant: 4
coefficent: 7, 18 (However, -1 can also be counted as a coefficient, it is just invisible!)
Step-by-step explanation:
coefficient: a numerical or constant quantity placed before and multiplying the variable in an algebraic expression
therefore, 7 and 18 are coefficients. HOWEVER, -1 can also be a coefficient to -z.
constant: a quantity or parameter that does not change its value whatever the value of the variables, under a given set of conditions.
therefore, 4 is a constant.

A sequence is defined recursively by the formula f(n + 1) = –2f(n). The first term of the sequence is –1.5. What is the next term in the sequence?
–3.5
–3
0.5
3
Answer:
The answer is 3
Step-by-step explanation:
It's just wisdom I mean think about it it
1.5 then 3
⭐ Initially, we have to find the reason why it was -1.5:
[tex]\large {\text {$ \sf f (n+1) = -2 f(n) $}}[/tex]
➡️ Having n, then we'll find the value of n, then we'll replace it with the found result.
[tex]\large {\text {$ \sf f (x+1) = -2.x = -1,5 $}}[/tex]
⌛ So, we will have to find what x is worth in this case:
[tex]\large {\text {$ \sf f ( 0,75 +1 ) = -2 \cdot 0,75 $}}[/tex]
[tex]\large {\text {$ \sf f ( 0,75) = -1,5 $}}[/tex]
→ Knowing this...
[tex]\large {\text {$ \sf f ( 1,5 + 1 ) = -2 \cdot 1,5 $}}[/tex]
[tex]\large {\boxed {\boxed {\sf f ( 2,5 ) = -3 }}}[/tex] [tex]\checkmark[/tex]

Consider statements in the table shown. Select True or False for each statement about the sequences of transformations that can
verify that square ABCD is congruent to square A'B'C'D'.
True False
Square ABCD is translated 9 units to the right, followed by a translation 6 units down.
Square ABCD is reflected across the y-axis, followed by a translation 6 units down.
Square ABCD is translated 6 units down, followed by a translation 9 units to the right.
Answers:
TrueFalseTrue==========================================================
Explanation:
Point A is at (-3, 4). If we apply the translation rule of "shift 9 units to the right and 6 units down", then we apply this transformation
[tex](x,y) \to (x+9,y-6)[/tex]
We add 9 to the x coordinate and subtract 6 from the y coordinate.
So (-3,4) becomes (-3+9, 4-6) = (6, -2) which is where point A' is located in the diagram. You should find that points B,C,D all map to B', C', D' following this same translation rule.
Therefore, statement 1 is true.
Statement 3 is the same idea, but the order has been swapped. The order doesn't matter in this case. So that makes statement 3 true as well.
-----------------------------------------------
Statement 2 on the other hand is false
Why? Because a reflection reverses the orientation of a figure. Note how both squares ABCD and A'B'C'D' all go clockwise when we go through the alphabet (ie A to B to C to D).
If a reflection happened, then A'B'C'D' would go counterclockwise and show that the orientation has been swapped. I recommend drawing an analogue clock and going up to a mirror to see that the orientation has swapped.
To swap the orientation back, you need a second reflection. This shows that two reflections either lead to a translation or a rotation (depending if the mirror lines are parallel or not).
If you wanted, you could track to see where point B ends up if you follow statement 2. Point B is at (-1, 4). Reflect over the y axis to get to (1, 4). Then shift 6 units down to arrive at (1, -2) which is not the correct location of B'. The diagram shows B' is actually at (8, -2). So this is an alternative way to see how statement 2 is false.

True
False

8. An car can hold 8 1/4 gallons of fuel. It contains 4 5/6 gallons of fuel. How
much more fuel is needed to fill the car?
Answer:
3 5/12
Step-by-step explanation:
Answer:
41/12 gallons
= 3 5/12 gallons
Step-by-step explanation:
Since it can hold 8 1/4 gallons and currently has 4 5/6 gallons, you subtract.
You need to get the common denominator to subtract cleanly so we can turn the fractions into improper fractions.
8 1/4 = 33/4 because 8 is equal to 8 full 4/4ths so multiply 8 by 4 and add 1 for the remaining 1/4.
Then 4 5/6 becomes 29/6 with the same concept earlier.
So we can change the denominator to 12 on both fractions (33/4 and 29/6) so we can subtract.
33/4 becomes 99/12 because they are still equivalent, it's just that you multiplied the top and bottom by the same number.
29/6 becomes 58/12 because we multiplied the fraction by 2/2.
Those two new fractions stated previously are the same as the original because we multiplied them by 1/1, because 3/3 and 2/2 is still equal to 1/1, and the new fractions can be simplified down to the original.
Since we have 99/12 and 58/12, we can subtract cleanly into
99 - 58 = 41
So the answer is 41/12
