Answer:
8m+3
Step-by-step explanation:
Let m be the number of lemon used in a pitcher of lemonade.
Serena sold 8 pitchers of lemonade, therefore she used 8m lemons.
Since there is a leftover of 3 lemons, we add:8m+3
Therefore:
Total number of lemons Serena has can be determined by the expression: 8m+3
where m is the number of lemons used in one pitcher of lemonade.

A card is drawn from a normal 52 card deck. The card number and sum are noted, the card is placed back in the deck, then another card is drawn. Find the probability that a) the first card was a queen and the second card as a 10. b) the first card was the Queen of Hearts and the second card was an 8. c) both cards were Jacks. d) the first card was the 5 of Spades and the second card was the Ace of Hearts.
Step-by-step explanation:
a) There are 4 Queens in a deck, so the probability the first card is a Queen is 4/52 = 1/13.
There are 4 10s in a deck, so the probability the second card is a 10 is 4/52 = 1/13.
The probability of both events is 1/13 × 1/13 = 1/169.
b) There is 1 Queen of Hearts in a deck, so the probability the first card is a Queen of Hearts is 1/52.
There are 4 8s in a deck, so the probability the second card is a 8 is 4/52 = 1/13.
The probability of both events is 1/52 × 1/13 = 1/676.
c) There are 4 Jacks in a deck, so the probability the first card is a Jack is 4/52 = 1/13.
There are 4 Jacks in a deck, so the probability the second card is a Jack is 4/52 = 1/13.
The probability of both events is 1/13 × 1/13 = 1/169.
d) There is 1 5 of Spades in a deck, so the probability the first card is a 5 of Spades is 1/52.
There is 1 Ace of Hearts in a deck, so the probability the first card is a Ace of Hearts is 1/52.
The probability of both events is 1/52 × 1/52 = 1/2704.

what is the relationship between the base of an exponential function and its rate of growth?
Answer:
growth rate is the number of times the base repeats
Step-by-step explanation:
We have that the general form of the exponential function is of the type:
f (x) = a ^ x
where "a" is the base and "x" is the exponent.
Therefore, the relation they keep to this exponent would be the growth rate since it is the number of times that the base is repeated, which means that the higher "x" is, the more times "a" is repeated.
The base of the function "a" is the point where the exponential curve cuts the y-axis while the value of "b" determines the rate of a growth rate pf decline rate.
Exponential functionThe standard exponential function is expressed as y = ab^x
where:
a is the y-interceptb is the ratex is the time taken.The base of the function "a" is the point where the exponential curve cuts the y-axis while the value of "b" determines the rate of a growth rate pf decline rate.

Identify the zero(s) of [tex]f(x)=4x^{2} - 20x - 56[/tex]. -- Urgent 10 minutes! Many points!
Answer:
x = - 2, x = 7
Step-by-step explanation:
Given
f(x) = 4x² - 20x - 56
To find the zeros let f(x) = 0, that is
4x² - 20x - 56 = 0 ( divide through by 4 )
x² - 5x - 14 = 0 ← in standard form
(x - 7)(x + 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 7 = 0 ⇒ x = 7

The location of k in Venn diagram is in II region.
What is Venn Diagram?A Venn diagram is a visual representation that makes use of circles to highlight the connections between different objects or limited groups of objects. Circles that overlap share certain characteristics, whereas circles that do not overlap do not. Venn diagrams are useful for showing how two concepts are related and different visually.
We have,
k ∈ A ∩ B means k is an element of both A and B.
The region I is or A only and the region I|I is only B.
and, the region II is for those whose share A and B.
Also, zone II is in between zone I and zone III which is both.

Solve the inequality
-7x + 12 = 75
Answer:
12/75 = 4/25
Step-by-step explanation:
Answer: x = -9
Explanation:
A student got 78 marks out of a possible 120. Express the students mark as a percentage
The student's mark can be expressed as 65%.
To express the student's mark as a percentage, you need to divide the number of marks obtained by the possible marks and multiply by 100.
In this case, the student got 78 marks out of a possible 120.
Percentage = (Marks Obtained / Possible Marks) * 100
Percentage = (78 / 120) x 100
Percentage = 0.65 x 100
Percentage = 65%
Therefore, the student's mark can be expressed as 65%.

A fountain is made up of two semicircles and a quarter circle. Find the perimeter of the fountain. Round your answer to the nearest tenth. The perimeter of the fountain is about a feet.
complete question:
A fountain is made up of two semicircles and a quarter circle. The diameter of the semicircles is 10 ft. Find the perimeter of the fountain. Round your answer to the nearest tenth. The picture is represented below.
Answer:
The perimeter of the fountain = 47.1 ft
Step-by-step explanation:
The fountain has 2 semi circle from a smaller circle with the diameter represented as 10 ft and a quarter circle from a bigger circle with the radius equals to 10 ft.
The perimeter is the distance around the fountain.The perimeter is the circumference in circular perspective. Therefore,
perimeter for a full circle = 2πr
Half circle = 2πr/2 = πr
For 2 half circle = πr + πr = 2πr
For 2 half circle = 2πr
r = 10/2 = 5
perimeter for 2 half circle = 2 × 5 × 3.14 = 31.4 ft
Perimeter for the quarter circle
r = 10 ft
Quarter circle perimeter = 1/4 × 2πr = πr/2
Quarter circle perimeter = (3.14 × 10)/2
Quarter circle perimeter = (31.4)/2
Quarter circle perimeter = 15.7 ft
The perimeter of the fountain = 15.7 ft + 31.4 ft = 47.1 ft

write an equation of the line that passes through the point (4,7) that is parallel to the line y = 3x+1
Explanation:
The given line y = 3x+1 has a slope of 3 as it is in the form y = mx+b
Any line parallel to this given line will also have a slope of 3. Parallel lines have equal slopes but different y intercepts.
Using m = 3 and (x,y) = (4,7), find the value of b
y = mx+b
7 = 3*4+b
7 = 12+b
12+b = 7
b = 7-12
b = -5
We have y = mx+b update to y = 3x+(-5) or y = 3x-5
Plug in x = 4 and you'll have y = 3x-5 turn into y = 7.

Write the equation of the hyperbola centered at the origin with focus (74, 0) and asymptote y=-7/5x
The equation of the hyperbola is =x^2/a^2-y^2/b^2=1
The equation of the given hyperbola is; x²/25 - y²/49 = 1
What is the equation of the hyperbola?
We are given;
Focus = (74, 0)
Asymptote; y = -⁷/₅x
Centered at origin
We are given that the general form of equation of a hyperbola is;
x²/a² - y²/b² = 1
Now, we know that the equations of the asymptotes are;
y = ±(b/a)x
Thus, comparing the above with our asymptote of y = -7/5x gives us;
a = 5 and b = 7
Thus, the equation of the given hyperbola is;
x²/5² - y²/7² = 1

Mr. Green tells you that a right angle has a hypotenuse of 13 and a leg of 5. She asks you to find the other leg of the triangle. Whats is your answer??
Answer:
Length of leg ⇒ 12
Step-by-step explanation:
Knowing this is a right angle triangle, let us apply Pythagorean Theorem to solve for the length of this other leg, which we can assign as x;
x^2 + 5^2 = 13^2 ⇒ square 5 and 13,
x^2 + 25 = 169 ⇒ subtract 25 from either side of equation,
x^2 = 144 ⇒ Take square root on either side,
Solution; Length of leg ⇒ 12
Polygon ABCD is defined by the points A(-4,2) B(-2, 4), C(1, 3) & D(2,2). Match the coordinates of the points of the transformed polygons to their correct values
Answer:
D'(-2, 2); C''(3, -1); A'''(4, -2); and B''(4, 2)
Step-by-step explanation:
See attachment for the figure.
For D', rotating the point (2, 2) 90° counterclockwise. This maps each point (x, y)→(-y, x); it takes (2, 2)→(-2, 2).
For C'', rotating the point (1, 3) 90° clockwise. This maps each point (x, y)→(y, -x); it takes (1, 3)→(3, -1).
For A''', rotating the point (-4, 2) 180° clockwise. This maps every point (x, y)→(-x, -y); it takes (-4, 2)→(4, -2).
For B'', rotating the point (-2, 4) 270° counterclockwise. This is the similar as rotating the point 90° clockwise. This maps every point (x, y)→(y, -x); it takes (-2, 4)→(4, 2).
