Mila went shopping for a new pair of pants because of a sale. The store was offering a 30% discount. What number should she multiply the prices on the tags by to find the price she would have to pay, before tax, in one step?
Answer:
Mila must multiply the price by 0.7 to obtain the price with the discount made.
Step-by-step explanation:
Since Mila went shopping for a new pair of pants because of a sale, and the store was offering a 30% discount, to determine what number should she multiply the prices on the tags by to find the price she would have to pay, before tax, in one step, the following calculation must be performed:
100 (price without discount) - 30 (discount) = X
100 - 30 = X
70 = X
70/100 = 0.7
Thus, Mila must multiply the price by 0.7 to obtain the price with the discount made.

Help! I have looked at so many lessons on writing exponential functions from a graph and nothing has helped.
Answer:
y = [tex]8(-\frac{1}{2})^x[/tex]
Step-by-step explanation:
Let the equation of the exponential function is,
y = a(b)ˣ
Since the graph of this function passes through two points [tex](4, \frac{1}{2})[/tex] and (3, -1)
For the point [tex](4, \frac{1}{2})[/tex],
[tex]\frac{1}{2}=a(b)^4[/tex] ---------(1)
For second point (3, -1),
-1 = a(b)³ ---------(2)
Divide equation (2) by equation (1),
[tex]\frac{\frac{1}{2}}{-1}[/tex] = [tex]\frac{a(b)^4}{a(b)^3}[/tex]
[tex]-\frac{1}{2}=b^{(4-3)}[/tex]
[tex]-\frac{1}{2}=b[/tex]
From equation (2)
-1 = [tex]a(-\frac{1}{2})^3[/tex]
-1 = [tex]-\frac{1}{8}a[/tex]
a = 8
Therefore, equation of the exponential function will be,
y = [tex]8(-\frac{1}{2})^x[/tex]
2x + 3 > 13
Whats the answer plz help
Answer:
In this case, you can simply treat the > sign like an = sign. The only time you would need to worry about is when multiplying or dividing by negative numbers.
2x + 3 > 13
2x + 3 - 3 > 13 - 3
2x > 10
2x / 2 > 10 / 2
x > 5
What does the value of the mean absolute deviation tell you about the spread of the data? HURRY PLEASE ILL GIVE 35 POINTS
Answer:
The Mean Absolute Deviation (MAD) of a set of data is the average distance between each data value and the mean. The mean absolute deviation is the "average" of the "positive distances" of each point from the mean. The larger the MAD, the greater variability there is in the data (the data is more spread out).

What is m∠Q=?
What does m∠R=?
What is m∠S=?
Answer:
89°, 123°, 91°Step-by-step explanation:
Inscribed angle is half of the intercepted arc.
m∠Q = 1/2(mPS + mRS) = 1/2(41° + 137°) = 89°Opposite angles are supplementary.
Supplementary angles sum to 180°.
m∠R = 180° - m∠P = 180° - 57° = 123°m∠S = 180° - m∠Q = 180° - 89° = 91°Are vacuoles small or large? PLS HELP I NEED THIS ANSWER FAST!

The median, range and mode of 8,7,12,7,11,10,7,12
Answer:
median is 7 because it's frequency is 3
Step-by-step explanation:
we were just learning these in o.maths.
The median,range and mode will be equal to 9,5 and 7.
What are the median, mode and range?The Median is the middlemost value of the numbers arranged in the ascending orders.
The mode will be defined as the number which is repeated mostly in the sequence.
The Range is the difference between the highest and the lowest value in the series.
The Median will be calculated as:-
7,7,7,8,10,11,12,12
median = (8+10)/2=9
The mode will be:-
7,7,7,8,10,11,12,12
Mode =7
The range will be:-
7,7,7,8,10,11,12,12
Range= 12-7=5
Hence the median,range and mode will be equal to 9,5 and 7.

Water flows from a faucet into a bathtub at a constant rate of 2.5 gallons per minute. The bathtub initially has 5 gallon of water in it.
Complete question :
Water flows from a faucet into a bathtub at a constant rate of 2.5 gallons per minute. The bathtub initially has 5 gallon of water in it. Write a function to represent the situation.
Answer:
f(x) = 2.5x + 5
Step-by-step explanation:
A function which could be used to represent the situation is the slope - intercept function ;
The constant rate of water flow per minute could represent the slope of the function, which is the change in y per unit change in x ;
The intercept is the initial water level in the bath tub = 5 gallons
Slope intercept equation:
y = mx + c
m = slope ; c = intercept
The water in the bathtub as a function of x, number of minutes is ;
f(x) = 2.5x + 5

How do I find the slope of a line?
Answer:
In order to find the slope of the line, find two points that are on the line and use the equation: m=(y2-y1)/(x2-x1). The 2 points should be whole numbers.
Answer:
Step-by-step explanation:
y2-y1
he first equation you need is m= ---------
x2-x1
x1 , y1 x2, y2
then you label the point like this ex: ( 2, -5) (1, 3)
and then place them in the places of the original eqatuion and you get your answer. but then you can simplify if you need too.
