Half of Isiah’s money is equal to ⅔ of Bob’s money. Isiah has $15 more than Bob. How much money do they have altogether?
The amount of money they have altogether is $105.
What is the system of equations that represent the question?i - b = $15 equation 1
1/2i = 2/3b
3i = 4b
i = 4b/3 equation 2
Where:
i = amount of money Isiah has
b = amount of money Bob has
How much money does Bob have?Substitute for the value of i in equation 1
4b/3 - b = $15
1/3b = $15
Multiply both sides of the equation by 3
b = $45
How much money does Isiah have?
Substitute for $45 in equation 1
i - $45 = $15
Add $45 to both sides of the equation
i = $45 + $15
i = $60
How much do they both have?
$60 + $45 = $105

A bag contains exactly 50 coins. The coins are either worth 10 cents, 20 cents or 50 cents and there is Atleast one of each. The total value of the coins is $10. How many different ways can this occur?
Answer:
This can happen in two ways:
1) 42 20-cent coins, 6 10-cent coins and 2 50-cent coins.
2) 30 10-cent coins, 10 20-cent coins and 10 50-cent coins.
Step-by-step explanation:
Given that a bag contains exactly 50 coins, and the coins are either worth 10 cents, 20 cents or 50 cents and there is at least one of each, and the total value of the coins is $ 10, to determine how many different ways can this occur, the following calculation must be performed:
48 x 0.5 + 1 x 0.2 + 1 x 0.1 = 24.30
48 x 0.1 + 1 x 0.2 + 1 x 0.5 = 5.5
48 x 0.2 + 1 x 0.1 + 1 x 0.5 = 10.3
45 x 0.2 + 4 x 0.1 + 1 x 0.5 = 9.9
44 x 0.2 + 5 x 0.1 + 1 x 0.5 = 9.8
42 x 0.2 + 6 x 0.1 + 2 x 0.5 = 10
30 x 0.1 + 10 x 0.2 + 10 x 0.5 = 10
Therefore, this can happen in two ways:
1) 42 20-cent coins, 6 10-cent coins and 2 50-cent coins.
2) 30 10-cent coins, 10 20-cent coins and 10 50-cent coins.

The upper right and lower left line segments both have slopes of -2/3. Since their slopes are the same, they are parallel. The slope is found by counting grid squares between points where the lines cross grid intersections. Those crossings occur down 2 and right 3 grid squares apart, so the slope is ...

A cylindrical fuel tank is 1.25 meters high and has
a radius of 0.60 meter. If the tank can only be
filled to an 85% capacity to allow for expansion
of the fuel, what is the maximum volume of fuel?
Answer:
The maximum volume of the fuel is:
[tex]V_{fuel}=1.20 \: m^{3}[/tex]
Step-by-step explanation:
The volume of the cylinder is given by:
[tex]V=\pi r^{2}h[/tex]
[tex]V=\pi (0.6^{2})(1.25)[/tex]
[tex]V=1.41 \: m^{3}[/tex]
If the tank can be filled to 85% of its capacity, the maximum volume of the fuel will be:
[tex]V_{fuel}=1.41*(\frac{85}{100})[/tex]
[tex]V_{fuel}=1.20 \: m^{3}[/tex]

A recent study indicated that the average cost of living for a family of four in various cities across the US was $65,351 with a standard deviation of $7712. A company is thinking about relocating to a city with a lower cost of living. They would like to choose a city in the bottom 30% of those surveyed. What is the cutoff for the cost of living that would make a city eligible for relocation by this company
Answer:
The correct answer is "57408".
Step-by-step explanation:
Given:
[tex]\mu=65351[/tex]
[tex]\sigma=7712[/tex]
[tex]p=0.15[/tex]
As per the standard table, we know,
[tex]z=-1.03[/tex]
Now,
⇒ [tex]z=\frac{x-\mu}{\sigma}[/tex]
By putting the values, we get
[tex]-1.03=\frac{x-65351}{7712}[/tex]
[tex]x=57407.64[/tex]
or,
[tex]=57408[/tex]

Which of the following set of side lengths could not be used to create a triangle? Provide your explanation.
a. 2 cm, 6 cm, 7 cm
b. 3 cm, 3 cm, 3 cm
c. 4 cm, 5 cm, 8 cm
D. 5 cm, 7 cm, 12 cm
9514 1404 393
Answer:
D. 5, 7, 12 cm
Step-by-step explanation:
In order for sides lengths to be able to form a triangle, the sum of the shortest two must exceed the longest. That is the case for all except D.
5 cm + 7 cm = 12 cm . . . . . is not greater than 12 cm
What is the volume of Maria's model in cubic centimeters?
a. 1,200 cu cm
b. 400 cu cm
c. 160 cu cm
d. 600 cu cm
Answer:
400 cu cm
Step-by-step explanation:
Volume = Length · width · height /3
Volume = 10 · 10 · 12 / 3
Volume = 1,200 / 3
Volume = 400 cu cm
The following examples illustrate the commutative property of multiplication.
5 · 2 · 9 = 2 · 5 · 9
3.14 · 2 = 2 · 3.14
Study the examples, then choose the statement that best describes the property.
a · b = a ÷ b
a · (b · c) = (a · b) · c
a · b = b · a
a · b = a · c
Derive the first three (non-zero) terms of Taylor's series expansion for the function
(a) f(x)=sin(x)f(x)=sin(x) about the origin and thereby estimate sin(0.2)=
Answer:
We want to find the first 3 terms of the Taylor's series expansion for f(x) = sin(x) around x = 0.
Remember that a Taylor's series expansion of a function f(x) around the point x₀ is given by:
[tex]f(x) = f(x_0) + \frac{1}{2!}f'(x_0)*(x - x_0) + \frac{1}{3!}*f''(x_0)*(x - x0)^2 + ...[/tex]
Where in the formula we have the first 3 terms of the expansion (but there are a lot more).
So, if:
f(x) = sin(x)
x₀ = 0
The terms are:
[tex]f(x_0) = sin(0) = 0[/tex]
[tex]\frac{1}{2!}*f(x_0)'*(x - x_0) = \frac{1}{2} cos(0)*(x - 0) = x/2[/tex]
[tex]\frac{1}{3!}*f(x_0)''*(x - x_0)^2 = \frac{1}{6}*-sin(0)*(x - 0)^2 = 0[/tex]
[tex]\frac{1}{4!}*f(x_0)'''*(x - x_0)^3 = \frac{1}{24}*-cos(0)*(x- 0)^3 = -\frac{x^3}{24}[/tex]
We already can see that the next term is zero (because when we derive the cos part, we will get a sin() that is zero when evaluated in x = 0), then the next non zero term is:
[tex]\frac{1}{6!}*f(x_0)''''*(x - x_0)^5 = \frac{1}{2*3*4*5*6} *(x - 0)^5 = \frac{x^5}{720}[/tex]
Then we can write:
[tex]sin(x) = \frac{x}{2} - \frac{x^3}{24} + \frac{x^5}{720}[/tex]
Evaluating this in x = 0.2, we get:
[tex]sin(0.2) = \frac{0.2}{2} - \frac{0.2^3}{24} + \frac{0.2^5}{720} = 0.099667[/tex]

Step-by-step explanation:
it is 4/10 or 40/100 because 100 - 60 = 40
and 60% as a fraction is 6/10 or 60/100
