Abe Cassidy wants to deposit the following into his savings account: 32 one-dollar bills, 4 five-dollar bills, 32 quarters, 25 dimes, 82 pennies, a check for $43.56, and a check for $122.90. He wants to receive a $50.00 bill in cash. How much will he deposit?
136.22
10.44
$229.78
$179.78
Answer:
179.78
Step-by-step explanation:
Let's count how much Abe has exactly:
32 one-dollar bills: $32
4 five-dollar bills: $20
32 quarters: $8
25 dimes : $2.50
82 pennies : $0.82
First check: $43.56
Second check: $122.90
Total = $229.78
And he wants a $50 bill... so he'll deposit $179.78 ($229.78 - $50).
Final answer:
Abe Cassidy will deposit $179.78 into his savings account.
Explanation:
Let's calculate how much Abe Cassidy will deposit into his savings account, considering he wants to receive a $50.00 bill in cash. To do this, we need to add up all the various types of money he has and then subtract the $50 he wishes to keep in cash.
32 one-dollar bills = $324 five-dollar bills = $2032 quarters = $8 (since 4 quarters = $1)25 dimes = $2.50 (since 10 dimes = $1)82 pennies = $0.82 (since 100 pennies = $1)1 check for $43.561 check for $122.90Adding all these amounts gives us a total of $229.78 before removing the $50 he wants in cash.
To find the amount he will deposit, we subtract the $50 from the total amount:
$229.78 - $50 = $179.78
Hence, Abe Cassidy will deposit $179.78 into his savings account.

What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
We are given that;
(x - 3)(x + 9) = -27
Now,
If we plug in x = 6 into the equation,
we get: (6 - 3)(6 + 9) = -27.
Simplifying, we get: (3)(15) = -27.
Multiplying, we get: 45 = -27. This is true, so x = 6 is a solution.
The other values of x do not satisfy the equation.
For example, if we plug in x = -9, we get: (-9 - 3)(-9 + 9) = -27. Simplifying, we get: (-12)(0) = -27.
Multiplying, we get: 0 = -27. This is false, so x = -9 is not a solution
Therefore, by quadratic equations the answer will be x = 6.

in a city, 35% of the bus riders with a monthly pass are students. in a random sample of 50 bus riders with monthly passes, 23 are students.
what is ρ and ρ with ^
Answer:
ρ = 35% or 0.35
ρ with ^ = [tex]\frac{23}{50}=0.46[/tex] or equivalently 46%
Step-by-step explanation:
ρ represents the population proportion of the bus riders, with a monthly pass, who are students.
The population proportion is simply the percentage of the entire population with a particular characteristic. We have been informed that in a city, 35% of the bus riders with a monthly pass are students. This means that 35% of the whole population of bus riders with a monthly pass are students. Therefore, our ρ is simply 35% or 0.35.
ρ with ^ represents the sample proportion of the bus riders, with a monthly pass, who are students. This is a statistic or an estimator as it is normally used to estimate the value of ρ, the population proportion. It is calculated using the formula;
ρ with ^ = [tex]\frac{x}{n}[/tex]
where n represents the size of the sample and x the number of individuals in the sample with a certain desired characteristic. We have been informed that;
in a random sample of 50 bus riders with monthly passes, 23 are students.
Using the above formula and the values given we have;
ρ with ^ = [tex]\frac{23}{50}=0.46[/tex] or equivalently 46%
Answer: The correct answer is: ρ=0.35, ρˆ=0.46

Dose anyone know number 7.
Answer: B
Step-by-step explanation: The Answer is B. 30 Sides.
The number of sides of the regular polygon each interior angle measuring 168° is 30. Thus, the correct option is B.
What is a polygon?A polygon is a planar figure characterised by a limited number of straight-line segments joined to create a closed polygonal chain in geometry. A polygon is defined as a bounded planar region, a bounding circuit, or both.
The measure of interior angles of a regular polygon is given by the formula,
[tex]\text{Measure of an interior angle} = \dfrac{(n-2) \times 180^o}{n}[/tex]
where n is the number of sides in the polygon.
Since it is given that measure of an interior angle of the polygon is 168°. Therefore, the number of sides will be,
[tex]168 = \dfrac{(n-2) \times 180^o}{n}[/tex]
168n = 180n - 360
180n - 168n = 360
12n = 360
n = 30
Hence, The number of sides of the regular polygon each interior angle measuring 168° is 30.

given [tex]f(x)= 4x^2 + 6x and g(x) = 2x^2 +13x+15 \\[/tex], find (f/x) (x)
Answer: [tex](f/g)(x)=\frac{2x}{x+5}[/tex]
Step-by-step explanation:
Given the function f(x):
[tex]f(x)=4x^2+6x[/tex]
And the function g(x):
[tex]g(x)=2x^2+13x+15[/tex]
To find [tex](f/g)(x)[/tex] you need to divide the function f(x) by the function g(x).
Therefore, knowing this, you get:
[tex](f/g)(x)=\frac{4x^2+6x}{2x^2+13x+15}[/tex]
You can simplify the numerator by factoring out 2x:
[tex](f/g)(x)=\frac{2x(2x+3)}{2x^2+13x+15}[/tex]
You have to simplify the denominator:
Rewrite the term 13x as a sum of two terms whose product be 30:
[tex](f/g)(x)=\frac{2x(2x+3)}{2x^2+(10+ 3)x+15}[/tex]
Apply Distributive property:
[tex](f/g)(x)=\frac{2x(2x+3)}{2x^2+10x+ 3x+15}[/tex]
Make two groups of two terms:
[tex](f/g)(x)=\frac{2x(2x+3)}{(2x^2+10x)+ (3x+15)}[/tex]
Factor out 2x from the first group and 3 from the second group:
[tex](f/g)(x)=\frac{2x(2x+3)}{(2x(x+5))+ 3(x+5)}[/tex]
Factor out (x+5):
[tex](f/g)(x)=\frac{2x(2x+3)}{(2x+3)(x+5)}[/tex]
Simplifying, you get:
[tex](f/g)(x)=\frac{2x}{x+5}[/tex]

The given functions are:
[tex]f(x) = 4 {x}^{2} + 6x[/tex]
and
[tex]g(x) =2 {x}^{2} + 13x + 15[/tex]
We want to find ,
[tex]( \frac{f}{g} )(x) = \frac{f(x)}{g(x)} [/tex]
[tex]( \frac{f}{g} )(x) = \frac{4 {x}^{2} + 6x }{2 {x}^{2} + 13x + 15} [/tex]
[tex]( \frac{f}{g} )(x) = \frac{2x(2x + 3) }{2{x}^{2} + 10x +3x + 15} [/tex]
[tex]( \frac{f}{g} )(x) = \frac{2x(2x + 3) }{2{x}(x + 5) +3(x + 5)} [/tex]
[tex]( \frac{f}{g} )(x) = \frac{2x(2x + 3) }{(2x + 3)(x + 5)} [/tex]
We cancel out the common factors to get:
[tex]( \frac{f}{g} )(x) = \frac{2x }{x + 5} [/tex]
where

Answer:
V = x³ + 10x² cm³
Step-by-step explanation:
The volume (V) of the triangular prism is calculated using the formula
V = area of triangular face × length
Area of triangular face = [tex]\frac{1}{2}[/tex] bh ( b is base and h is height )
here b = 2x and h = x, thus
A = [tex]\frac{1}{2}[/tex] × 2x × x = [tex]\frac{1}{2}[/tex] × 2x² = x²
length = x + 10, hence
V = x²(x + 10) = x³ + 10x²
A pet toy manufacturer is designing a plastic ball for dogs that will float in water. In order for the ball to float it must have a density that is less than 1 gram per milliliter (the density of water). The approved design has a mass of 115 grams and a density of 0.600 g/mL. Use the density formula d = m v to determine the radius of the ball to the nearest hundredth of a centimeter. Volume of a sphere = 4 3 π r 3
Answer:
3.576 cm
Step-by-step explanation:
radius of ball, r=?

On Saturn year equals 29.5 earth years. If you were three years old on Saturn how old would you be on earth
Answer 88.5 I think I don’t know if it’s right
Step-by-step explanation:
Multiply it by 3
If you were three years old on Saturn, which has a year length equivalent to 29.5 Earth years, you'd be 88.5 years old on Earth.
Explanation:The subject of your question is focused on the comparison of time passage on different planets--in this case, how years on Saturn compare to years on Earth. In terms of the Solar system, a year on any planet is determined by how long it takes to orbit the Sun. Given that one Saturn year equals 29.5 Earth years, if you were three years old on Saturn, you'd be 88.5 years old on Earth (Because 29.5 * 3 = 88.5).
This is calculated simply by multiplying the number of Saturn years by the equivalent in Earth years. This concept can be applied to other planets as well, as each has its own specific length of year based on its orbit around the Sun.
