Given:
[tex]\dfrac{?}{5}+\dfrac{18}{20}=\dfrac{30}{20}[/tex]
To find:
The missing value.
Solution:
Let x be the missing value.
We have,
[tex]\dfrac{x}{5}+\dfrac{18}{20}=\dfrac{30}{20}[/tex]
[tex]\dfrac{x}{5}+\dfrac{9}{10}=\dfrac{3}{2}[/tex]
Subtract [tex]\dfrac{9}{10}[/tex] from both sides.
[tex]\dfrac{x}{5}=\dfrac{3}{2}-\dfrac{9}{10}[/tex]
[tex]\dfrac{x}{5}=\dfrac{15-9}{10}[/tex]
[tex]\dfrac{x}{5}=\dfrac{6}{10}[/tex]
[tex]\dfrac{x}{5}=\dfrac{3}{5}[/tex]
Multiplying both sides by 5, we get
[tex]x=3[/tex]
So, the missing value is 3.
Therefore, the correct option is C.
hey it is pretty late i hope u get your work done and get good sleep and have some points
Answer:
Thanks for the points. ❤❤What is a polynomial function in standard form with zeros 1, 2, 3, and –3? (1 point)
x
4 – 3x
3 + 7x
2 – 27x – 18
x
4 + 3x
3 – 7x
2 – 27x – 18
x
4 – 3x
3 – 7x
2 + 27x – 18
x
4 + 3x
3 + 7x
2 – 27x – 18
Step-by-step explanation:
By Factor Theorem, we have:
(x - 1)(x - 2)(x - 3)(x + 3)
= (x² - 3x + 2)(x² - 9)
= x⁴ - 3x³ - 7x² + 27x - 18.
does the equation -x+4y=-2 represent a direct variation. if so what is the constant variation
Answer:
Yes it represents.
Variation tax = 0,25
Step-by-step explanation:
Direct variation is the name we gave to the rate of change of a first degree function.
A first degree generic function is:
y = f(x) = ax + b
Now observe the question's function:
- x + 4y = -2
4y = x - 2
y = 1/4x - 2/4
y = f(x) = 0,25x - 0,5
0,25 is our constant variation, because any number that x assume will be multiplied by 0,25.
k/3.8 + 57.6 = 28.3
The value of k is =
Answer:
k = -111.34
Step-by-step explanation:
In this question, you will solve for k.
Solve:
k/3.8 + 57.6 = 28.3
Subtract 57.6 from both sides.
k/3.8 = -29.3
To get "k" by itself, multiply both sides by 3.8 to eliminate the fraction.
k = -111.34
-111.34 is the value of "k".
Five members of the Varsity Math team are running late for a big
competition and hurrying toward the arena - but they forgot that they would
have to cross the stream that cuts through campus. When they reach the
stream, there's a small boat tied up on their side that they can "borrow" to get
to the other side.
The boat will hold one, two or three of the students, but not more.
Fortunately, two of the team members are also on the crew team, and when
the boat contains only one or both of them, they can make it across the stream
in one minute. Unfortunately, the other three teammates are very
inexperienced with boats, and when any of them is aboard, there is so much
awkwardness and flailing that the crossing will take four minutes, regardless
of whether one of the crew teammates is on board.
The team members adopt the fastest strategy for rowing back and forth
across the stream to get everyone to the other side for the competition. How
many minutes does it take all five team members to get across?
Answer:
8 min
Step-by-step explanation:
Crew C =2
loser L =3
min 1 2C goes
min 1 1C comes
min 4 3L goes
min 1 1C comes
min 1 2C goes
total min 8

Answer:
80%
Step-by-step explanation:
First, add all the numbers up to get 76.
Then, add the dogs, hamsters, and fish to get 61.
Finally, divide 61 by 76 to get 0.80
So, 80% of students had dogs, hamsters and fish.

Two points (4,1) and (4,2) lie on a vertical line. Find the slope of the line that passes through both points. (5 points) m= 0 or no slope undefined slope m=1/2 m = 1
Answer:
the slope of a vertical line is undefined
Step-by-step explanation:
its undefined because it doesn't move horizontally. however if you had a horizontal line, the slope would be 0
is it bad if you over think to much (ik its not question but i really dont no one to talk to rn so ....)
if you get the right answer, no. if you get the wrong answer yes
it all depends on what the question is and such
Answer: No not unless it affects you and your mental health
Step-by-step explanation:
Im a huge over thinker and i blame myself for a lot of things that arent even my fault. Over thinking things isnt always the best way to go you should always have someone to talk to. If your feeling worthless or down just know you are enough! You are perfect and dont try to change it for anyone. Its not bad to overthink unless it affect you so greatly that it hurts to smile. I know times are tough right now but you will get through it just stay strong. I hope this helped :)

Answer
C but then again i might be wrong
Answer:
C) (6,8) Is your answer
Step-by-step explanation:
point b(2,5)
remember
(x,y)
x=moves left or right
y moves up or down
so 4 units left and 3 units up
if you go left or down u subtract if you go right or up you add
so
(2,5)+(4,3)
=
(6,8)

( 2/3 + 4/5 ) ÷ 3 /6 will give
22/15
44/15
11/15
Step-by-step explanation:
(2/3 + 4/5) / (3/6)
= (10/15 + 12/15) * 2
= (22/15) * 2
= 44/15.
Your princpal has decided to provide a treat to everyone in your grade before thanksgiving break-ice cream bars! One box contains 48 bars. There are 338 students in your grade. How many boxes does he need to purchase?
Answer:
8 boxes approx
Step-by-step explanation:
Step one:
given data
One box contains 48 bars
Required
The number of boxes needed for a total of 338 students if each person is to get at least one bar.
Step two:
this can be gotten by dividing 338 by the number of the bar in a box
= 338/48
=7.04
=8 boxes approx
He needs to purchase at least 8 box
On a certain day, a bakery produced a batch of rolls at a total production cost of $300. On that day, 4 5 of the rolls in the batch were sold, each at a price that was 50 percent greater than the average (arithmetic mean) production cost per roll. The remaining rolls in the batch were sold the next day, each at a price that was 20 percent less than the price of the day before. What was the bakery's profit on this batch of rolls
Answer:
$108
Step-by-step explanation:
Let number of rolls produced = [tex]x[/tex]
Total production cost = $300
Average production cost can be found by dividing the total production cost with the number of rolls produced.
Average production cost per roll = $[tex]\frac{300}{x}[/tex]
[tex]\frac{4}{5}[/tex] of the rolls were sold at a price 50% higher than the average production cost per roll.
i.e.
Money earned by selling [tex]\frac{4}{5}[/tex] of the rolls:
[tex]\dfrac{4}{5}x \times \dfrac{300}{x}\times \dfrac{150}{100}\\\Rightarrow \$360[/tex]
Money earned by selling the remaining the remaining rolls:
[tex]\dfrac{1}{5}x\times \dfrac{300}{x}\times \dfrac{80}{100}\\\Rightarrow \$48[/tex]
Total money earned by selling all the rolls = $360 + $48 = $408
Total profit can be calculated by subtracting the total production cost from the total money earned.
Total profit = $408 - $300 = $108

6. a) The coordinate of the y-intercept is (0, 4)
b) The y-intercept represent the initial distance before she started hiking
7. The domain of the function is 0 ≤ c ≤ ∞
8. The correct option is;
b. all real numbers from 2.6 to 13"
9. Please find attached the required graph of the function created with Microsoft Excel
Step-by-step explanation:
6. From the given graph, we have;
The coordinate of the y-intercept = (0, 4)
The y-intercept represent the initial distance before she started hiking
7. The given function that models the number of cans Luis will have after his purchase is f(c) = 24·c + 5
The domain of the function is the possible values of "c", which is 0 ≤ c ≤ ∞
∴ The domain of the function = 0 ≤ c ≤ ∞
8. The number of hours Roger plays video games, t is 2 ≤ t ≤ 5
The number of games Roger plays on average within an hour = 2.6 games
The function f(t) = 2.6·t gives the number of games Roger plays in "t" hours
Therefore, we have;
The range = f(2) ≤ f(t) ≤ f(5) = 2.6 × 2 ≤ f(t) ≤ 2.6 × 5 = 5.2 ≤ f(t) ≤ 13
The range of the function = 5.2 ≤ f(t) ≤ 13
The correct option is "b" " all real numbers from 2.6 to 13"
9. Please find the required graph of the function [tex]f(x) = -\left | x - 2 \right | + 3[/tex], created with Microsoft Excel.
When a figure is rotated, does every point move the same distance? Explain. *
No. The angle of rotation is different for each point, and each point and its image are, therefore, different distances from the center of rotation, so the distance each point moves varies.
Yes. Since the angle of rotation is the same, the distance that each point moves is the same.
No. Although each point is rotated through the same angle, points that are different distances from the center of rotation move different distances.
Yes. When rotating a figure, the rotation indicates that each point moves the same distance, such that the angle of rotation may vary from point to point.
Answer:
Yes. Since the angle of rotation is the same, the distance that each point moves is the same.
Step-by-step explanation:
Answer Yes. Since the angle of rotation is the same, the distance that each point moves is the same i think
