Greg studied for 12 minutes. This is 40% of the time he wants to study today. How many more minutes does Greg need to study today?
Answer:
18 More Minutes
Step-by-step explanation:
Hi,
I think I can help.
What I would first do here is try to find the value of 10% relative to the 12 minutes. If we find what 10% is we can multiply that to get 100% to find the total amount of minutes he wants to study. We can then subtract the time already studied to find our answer.
To do this we want to take the 40% we have and find 10. We can do 40/4 to find this since 40 divided by 4 is actually 10.
But if we do this we also have to do with to the number it is relating to / representing. Which is 12. (12 minutes = 40%)
So we can do :
40 / 4
=
10%
Also
12 / 4
=
3
So with this we can conclude that 10% of his total time is 3 minutes.
Now lets multiply this by 10 to get the 100% we are looking for so we can get the total amount of time he spent studying.
So :
10% x 10
=
100%
3 x 10
=
30 minutes
So his total time is 30 minutes of studying, but we have to find how many more minutes after his 12.
We can now simply take the total time and take off the time spent already to find this answer :
30 - 12
=
18 minutes
That is your answer, he needs to study 18 more minutes.
I hope this helps!

Simplify: ( x² − 3) ( x + 2) + 6 *
Answer:
x(x + 3)(x - 1)
Step by Step :::
= (x² - 3)(x + 2) + 6
= x(x² - 3) + 2(x² - 3) + 6
= x³ - 3x + 2x² - 6 + 6
= x³ + 2x² - 3x
= x(x² + 2x - 3)
= x(x² + 3x - x - 3)
= x{x(x + 3) - 1(x + 3)}
= x(x + 3)(x - 1)

Which type of function best models the data?
A.
a linear function with a positive slope
B.
a quadratic function with a positive value of a
C.
a quadratic function with a negative value of a
D.
a square root function
Answer:
C
Step-by-step explanation
you need desmos for this
Plug in the table and also plug in y_{1}\sim ax_{1}^{2}+bx_{1}+c and you find the a and b values. a is shown as a negative number, and the graph's U shape means it's quadratic.
The required function that best models the data is a linear function with a positive slope. Option A is correct.
Given a table,
Years After Opening 1 2 3 4 5 6 7
Number of Employees 100 348 405 575 654 704 746
Which type of function best models the data to be determined
Functions are the relationship between sets of values. e g y = f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Since looking forward to the data given,
It can be seen that the data first increased rapidly then it become moderate. Thus it means the relationship starts with a positive intercept.
This implies that the given relationship is linear and with a positive slope.
The required function that best models the data is a linear function with a positive slope.

If x = 9 units, y = 3 units, and h = 7 units, find the area of the rhombus shown above using decomposition. A. 21 square units B. 13 square units C. 72 square units D. 63 square units
Answer:
63 square units
Step-by-step explanation:
Area of the rhombus = Base × Height
Given
Base = x = 9unit
Height = h = 7units
Substitute into the formula
Area of the rhombus = 9×7
Area = 63units²
Hence the required area of the rhombus is 63 square units

Carlos jogged 5 laps around the school track in 8 minutes. What was his average speed in laps per minute? lap(s) per minute PLEASE I NEED ANSWER I WILL GIVE BRAINYLIST
Answer:
To solve this problem, you would create two ratios and make them equal to each other, both representing laps:minute or laps/minute! With that being said, laps will be in the numerator, or on top, and minutes will be in the denominator, or the bottom! The first ratio, which we know from the problem, will be 5/8. In order to write the second ratio, we need to come up with something to put in place for what we're solving for. I like to use x. So, we need to find how many laps (x) are run in 1 minute. Remember, laps are on top and minutes are on the bottom. The second ratio would look like x/1. Then we make them equal to each other -> 5/8=x/1. You would then solve this equation by multiplying the right side of the equation by the reciprocal of the denominator! So, it would be 1/1(5/8)=x. Because then multiple the numerators and the denominators -> 1(5)=5 and 1(8)=8! This makes the equation turn into x=5/8! Because x equals the number of laps run in one minute, we can say that Ricky ran 5/8 of a lap in one minute or 0.625 laps in one minute!

A point moves in the plane of two perpendicular lines so that the product of its distances from the lines always is 12 when the point is 4 units from one of the lines, its distance from that line is decreasing at the rate of 2 units/min. At what rate is the distance from the other line changing at that moment?
I'm not sure how this situation would look so if someone could draw or make a diagram/graph for me (on Desmos or something), I would really appreciate it!
The rate is the distance from the other line changing at that moment will be negative 1.5 units per minute.
What is differentiation?The rate of change of a function with respect to the variable is called differentiation. It can be increasing or decrease.
A point moves in the plane of two opposite lines so the result of its good ways from the lines forever is 12 when the fact of the matter is 4 units from one of the lines, its separation from that line is diminishing at the pace of 2 units/min.
Let the coordinate of the pointe be (x, y). Then the function is given as,
[√(x- 0)²] [√(y - 0)²] = 12
[√x²] [√y²] = 12
x y = 12
At x = 4, the value of the variable 'y' is given as,
4y = 12
y = 3
Differentiate the function with respect to time, then we have
xy' + yx' = 0
4 × y' + 3 × 2 = 0
y' = - 6 / 4
y' = - 1.5 units per minute
The rate is the distance from the other line changing at that moment will be negative 1.5 units per minute.

Answer:
480
Step-by-step explanation:
sorry if its wrong bro
Step-by-step explanation:
a- for 15 biscuits:
sugar=60g
for 60 biscuits, she will need:
sugar=240, as she would make 15 biscuits 4 times to get a total of 60 biscuits
the amount of flour must be 3×sugar used
so amount of flour she needs is 720g
b i- she needs a total of 480g butter as butter is 2× of sugar used
ii- since she buys in 250g packs, she would have to buy 2 packs
20 g will be left after she finishes making the biscuits

2. Classify the angle as acute, obtuse, right or straight.
O acute
O obtuse
Oright
straight
HELP ASAP
Answer:
Please include the details of the angle
Step-by-step explanation:
When the angle is 93 degrees, the the angle is a obtuse angle. option B is correct.
Given that the measure of angle A is 93 degrees, we can classify the angle as follows:
Angle A = 93 degrees
We know that if angle is less than 90 degrees, it is acute.
if angle is greater than 90 degrees, it is obtuse.
if angle is equal to 90 degrees, it is right angle.
Since the angle measures greater than 90 degrees, it falls within the range of an obtuse angle.
Therefore, the correct classification for angle A is obtuse.

Write the equation of the line in Slope-Intercept form given the following information: The new line is PARALLEL to y = 3x - 5 The new lines goes through the point (-2, 6).
Answer:
y = 3x + 12
Step-by-step explanation:
y = 3x - 5 (y = 3x +b)
Parallel lines have same slope.
m = 3; (-2 , 6)
y - y1 = m(x -x1)
y - 6 = 3(x -[-2])
y -6 = 3(x + 2)
y - 6 = 3x + 6
y = 3x + 6 + 6
y = 3x + 12
