Step-by-step explanation:
there are 16 ounces in a pound
so that means that 5 pounds (lbs) equals 80 ounces, you find this out by multiplying 16 and 5.
to find out how many batches are in a 5lb container then you just divide 80 and 24 which equals... 3.333333 but you just need to round it.

Answer:
[tex]x = 2, y = -3[/tex]
Step-by-step explanation:
Add the 2 equations together, then solve for x.
[tex](2x + 2y) + (3x - 2y) = (-2) + (12)\\ 2x + 3x + 2y - 2y = -2 + 12\\5x = 10\\x = 2[/tex]
Now that we know the value of x, we can easily find y by substitution.
[tex]3x - 2y = 12\\3(2) - 2y = 12\\6 - 2y = 12\\-2y = 6\\y = -3[/tex]

Using the probability concept, it is found that since the number of red sweets would be a decimal number, the probability cannot be [tex]\dfrac{7}{10}[/tex]
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
In this problem:
In total, there are 8 + n sweets in the bag.Of those, n are red.The probability of red is:
[tex]p=\dfrac{n}{n+8}[/tex]
Supposing, we solve for n:
[tex]\dfrac{n}{n+8} = \dfrac{7}{10}[/tex]
10n = 7n + 56
3n = 56
n = 56 / 3
n = 18.67

Drag a value to each box to correctly express the answer in polar form and then in rectangular form.
a. (2 - 2i√3)⁴ in polar form is 256(cos(-4π/3) + isin(-4π/3)) = 256cis(-4π/3)
b. (2 - 2i√3)⁴ in rectangular form is -128 + 128√3
To answer the question, we need to know what complex numbers are
What are complex numbers?Complex numbers are numbers of the form z = x + iy
a. Complex numbers in polar formComplex numbers in polar form z = r(cosθ + isinθ) where
r = √(x² + y²) and θ = tan⁻¹(y/x)Given that z = (2 - 2i√3)⁴ =
So,
x = 2 and y = -2√3So, converting to polar form
r = √(x² + y²)
= √[2² + (-2√3)²]
= √[4 + 4(3)]
= √[4 + 12]
= √16
= 4
θ = tan⁻¹(y/x)
θ = tan⁻¹(-2√3/2)
θ = tan⁻¹(-√3)
θ = -π/3
So, z = r(cosθ + isinθ)
= 4(cos(-π/3) + isin(-π/3))
Powers of complex numbersA complex number z raised to power n is zⁿ = rⁿ(cosnθ + isin(nθ)]
z⁴ = (2 - 2i√3)⁴
= r⁴(cos4θ + isin4θ)
= 4⁴(cos(4 × -π/3) + isin(4 × -π/3))
= 256(cos(-4π/3) + isin(-4π/3))
= 256cis(-4π/3)
(2 - 2i√3)⁴ in polar form is 256(cos(-4π/3) + isin(-4π/3)) = 256cis(-4π/3)
b. Complex numbers in rectangular formThe complex number z = r(cosθ + isinθ) in rectangular form is z = x + iy where
x = rcosθ and y = rsinθGiven that z⁴ = 256(cos(-4π/3) + isin(-4π/3)) in rectangular form,
x = rcosθ
= 256(cos(-4π/3)
= 256cos(-4 × 60°)
= 256cos(-240)
= 256cos(240)
= 256 × -1/2
= -128
y = rsinθ
= 256sin(-4π/3)
= 256sin(-4 × 60°)
= 256sin(-240)
= -256sin240
= -256 × -√3/2
= 128√3
So, z⁴ = x + iy
= -128 + 128√3
So, (2 - 2i√3)⁴ in rectangular form is -128 + 128√3

Step-by-step explanation:
just find the equal difference of y values.
Step-by-step explanation:
to add to the explanation :
an arithmetic sequence is defined as
an = an-1 + d
so, every term of the sequence is created by adding the same constant d (the common difference) to the previous term.
therefore, you find the common difference by finding the difference of 2 sequential terms.
like here e.g.
a3 = 38
a4 = 53
53 - 38 = 15
bingo !
and to verify that it truly is an arithmetic sequence, we can quickly also check the differences between the other pairs. yes, they are all 15.
be prepared for a trap like
1 8
2 23
3 38
5 68
notice the sudden jump in x ? suddenly x is increased by 2.
that just means we compare
an and an-2 instead of an-1.
so, how is related to an-2 ?
an = an-1 + d = (an-2 + d) + d = an-2 + 2d
and so we would get
a3 = 38
a5 = 68
a5 - a3 = 2d = 30
d = 15
so, don't get confused by such jumps or gaps.

a. Let B represent the volume of Box B in cubic centimeters. Write an equation that could be used to determine the volume of Box B.
b. Solve the equation to determine the volume of Box B
What is volume?Volume is simply the amount of space that is enclosed within a container.
Given that;
Sum of the volume of two rectangular prisms A&B = 14.325cm³Volume of Box A = 5.61cm³a)
Let B represent the volume of Box B in cubic centimeters. The equation that could be used to determine the volume of Box B will be;
Sum of the volume of two rectangular prisms A&B = Volume of Box A + Volume of Box B
14.325cm³ = 5.61cm³ + B
B = 14.325cm³ - 5.61cm³
Hence, The equation that could be used to determine the volume of Box B is B = 14.325cm³ - 5.61cm³
b)
To determine the volume of Box B, we solve the equation.

What is the y-intercept of f(x) = 3x 2? a. (9,0) b. (0,9) c. (0,-9) d. (9,-9)
Answer:
f(x) = 3x + 9: y - intercept is option c. (0,-9)
f(x) = 3x - 9: y - intercept is option b. (0, 9)
Step-by-step explanation:
option a and d cant be correct since y = 0 in those answer when the y - intercept is when x = 0
If the function f(x) = 3x + 9
than x = 0
f(x) = 3(0) + 9
f(x) = 0 + 9
f(x) = 9
x = 0 and y = 9 (0, 9)
If the function f(x) = 3x - 9
than x = 0
f(x) = 3(0) - 9
f(x) = 0 - 9
f(x) = -9
x = 0 and y = -9 (0, -9)
