Answer:
15 rounds
Step-by-step explanation:
Change 75% into a decimal (0.75).
Multiply 20 by 0.75.
When doing so, you get 15 rounds.
To check this: 15/20 = 3/4 = 0.75
Answer:
if that student is scussordbhe then they won 15 rounds, if they arent they won 5.

If you spent 58 minutes doing English homework and 47 minutes doing math homework how much more time did you need to spend doing English homework?
Answer:
58 minutes
Step-by-step explanation:
Please brainliest me
There are 11 minutes more time to spend doing English homework.
What is mean by Subtraction?
Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
If you spent 58 minutes doing English homework and 47 minutes doing math homework.
Now,
Since, The time for doing English homework = 58 minutes
And, The time for doing Math homework = 47 minutes
So, The time more to spend doing English homework = 58 - 47
= 11 minutes
Thus, There are 11 minutes more time to spend doing English homework.

Algebra - Question related to graphs?
A plane that carries mail makes a round trip each day from Chicago to New York. It makes 3 intermediate stops on the way to New York and 1 intermediate stop on the way back to Chicago. Suppose you make a graph of the altitude of the plane for one day, with time on the horizontal axis and altitude on the vertical axis. How many times will the graph touch the horizontal axis?
Well, the only time the graph would touch the x-axis (horizontal axis) would be at 0 altitude so, counting the 3 stops on the way to NY then the 1 stop back to Chicago would be four. But if you think about it when the planes are at it's destination it's also at 0 altitude. So you'd add another 3 (Chicago to New York then back to Chicago)...right? Then the graph would touch x-axis approximently 7 times?
Dose that make sense?
1: Yes
Way out.
NY,S1,S2,S3,Ch
Way back

The Ch is the same therefore total is 7.
2:

3: Well, the only time the graph would touch the x-axis (horizontal axis) would be at 0 altitude so, counting the 3 stops on the way to NY then the 1 stop back to Chicago would be four. But if you think about it when the planes are at it's destination it's also at 0 altitude. So you'd add another 3 (Chicago to New York then back to Chicago)...right? Then the graph would touch x-axis approximently 7 times.........

i guess it would be 7 as the answer because: Well, the only time the graph would touch the x-axis (horizontal axis) would be at 0 altitude so, counting the 3 stops on the way to NY then the 1 stop back to Chicago would be four.

Step-by-step explanation: Different Brainly's
1: Answer: 7
Step-by-step explanation: The graph that is drawn here shows the altitude as a function of time. When the plane takes off from Chicago, the graph will start from the horizontal axis.
Next, when the plane takes 3 intermediate stops, altitude will touch the horizontal axis 3 times.
Next, when the plane lands in New York the altitude will touch the horizontal axis.
Next, when plane takes off from New York and takes an intermediate stop, altitude will touch horizontal axis.
Lastly the altitude will touch the axis when plane lands back in Chicago.
So, cumulatively the altitude will touch the horizontal axis seven times.
2: I Don't Know
3: Answer:
5 is the right answer
Step-by-step explanation:
The graph will touch the horizontal x each time the altitude is zero.
Tha happens: 1st in Chicago before taking off, 2nd, in the intermediate place before getting to NY, 3rd in NY, 4th in the intermediate place before getting to Ch, and 5th when arrives to Ch.

PLEASE HELP ILL GIVE BRAINLIEST! PLEASE PUT X AND Y PLOT POINTS! x-3y=3 2x+9y=11
Answer:
( x, y ) = ( 4, 1/3)
Step-by-step explanation:
x - 3y = 3
2x +9y = 11
1. substitute the value of x
x= 3 + 3y
2x + 9y = 11
2. solve equation
2 (3 + 3y) +9y = 11
3. substitute the value of y
y = 1/3
4. solve equation
x = 3 + 3 x 1/3
x = 4
5. check solution
(x, y) = ( 4, 1/3 )
check x ----> 4 - 3 x 1/3 = 3
check y ------> 2 x 4 + 9 x 1/3 = 11
for x----> 3=3
for y----> 11=11
Complete the square
to find the vertex
of this parabola.
x?+8y+2x - 23=0
Answer:
The vertex of the parabola is;
([-1], [3])
Step-by-step explanation:
The given quadratic equation is presented as follows;
x² + 8·y + 2·x - 23 = 0
The equation of the parabola in vertex form is presented as follows;
y = a·(x - h)² + k
Where;
(h, k) = The vertex of the parabola
Therefore, we have;
x² + 8·y + 2·x - 23 = 0
8·y = -x² - 2·x + 23
y = 1/8·(-x² - 2·x + 23)
y = -1/8·(x² + 2·x - 23)
y = -1/8·(x² + 2·x + 1 - 23 - 1) = -1/8·(x² + 2·x + 1 - 24)
y = -1/8·((x + 1)² - 24) = -1/8·(x + 1)² + 3
Therefore, the equation of the parabola in vertex form is y = -1/8·(x + 1)² + 3
Comparing with y = a·(x - h)² + k, we have;
a = -1/8, h = -1, and k = 3
Therefore, the vertex of the parabola, (h, k) = (-1, 3).
Use the graph below to solve the equation. (Find the solutions or the roots)

Trapezoid: b1 =3m; b2 = 4m
A= 7m 2 What the next missing dimension?
9514 1404 393
Answer:
h = 2m
Step-by-step explanation:
We can put the given values into the area formula and solve for the missing one.
A = (1/2)(b1 +b2)h
7m²= (1/2)(3m +4m)h
7m² = (7/2)m·h
(7m²)(2/(7m)) = h = 2m
The missing height is 2 m.

Answer:
{-1/2, -1/4, 1/2}
Step-by-step explanation:
x > - 1 can be voiced as "x is greater than -1." In other words, any x value greater than -1 satisfies this inequality.
1/2 is greater than -1. 1/2 lies to the right of -1.
-1/2 is greater than -1.
-1/4 is greater than -1.
-5/2 is the same as -2 1/2. This is smaller than -1. Eliminate this choice

The perimeter of a quadrilateral is 336.
The ratio of the sides is 2: 3: 2: 5. Find
the side lengths.
Just trying to win the CONTEST BUT GOOOOD LUCK
Answer:
56 units, 84 units, 56 units, 140 units
Step-by-step explanation:
Since you have the ratios, you can multiply each by x, because you do not know the actual values.
2x+3x+2x+5x=336
12x=336
÷12 ÷12
x=28
Then, plug in the values of x.
So 2*28= 56
3*28=84
2*28=56
5*28=140

PLEASE HELP WILL GIVE BRAINLIEST
Answer:
Step-by-step explanation:
The graph of a quadratic function is a U-shaped curve called a parabola. One important feature of the graph is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value. In either case, the vertex is a turning point on the graph. The graph is also symmetric with a vertical line drawn through the vertex, called the axis of symmetry. These features are illustrated in (Figure).
Graph of a parabola showing where the x and y intercepts, vertex, and axis of symmetry are.
The y-intercept is the point at which the parabola crosses the y-axis. The x-intercepts are the points at which the parabola crosses the x-axis. If they exist, the x-intercepts represent the zeros, or roots, of the quadratic function, the values of x
at which
y = 0

Which of the following equations is true to find the length BC?
Answer:
BC/sin 23 = 10/sin 47
Step-by-step explanation:
Here, we want to select the true equation to find the length BC
From the question, we have the angle facing side BC; also, we have the angle and the side facing it for another side
In this situation, the best way to solve for BC is by the use of the sine rule
The sine rule states that the ratio of the length of a side and the sine of the angle facing the side is constant for a given triangle
Thus, we have it that;
BC/sin 23 = 10/sin 47
