the table shows the prices for different party toy packages from the Tomtown Toy Company.Which item costs the least per toy? Explain your reasoning
Answer:
Dominoes costs the least per toy.
Step-by-step explanation:
From the given table it is clear that
Cost of 6-pack of Dominoes = $3.98
Cost of 1-pack of Dominoes = [tex]\frac{\$3.98}{6}\approx \$0.663[/tex]
The cost of 1-pack of Dominoes is $0.663.
Cost of 12-pack of Peg Games = $9.99
Cost of 1-pack of Peg Games = [tex]\frac{\$9.99}{12}=\$0.8325[/tex]
The cost of 1-pack of Peg Games is $0.8325.
Cost of 24-pack of Mini Footballs = $17.98
Cost of 1-pack of Mini Footballs = [tex]\frac{\$17.98}{24}\approx $0.75[/tex]
The cost of 1-pack of Mini Footballs is $0.75.
$0.663 is less than $0.8325 and $0.75. It means dominoes costs the least per toy.
Factor the expression.

Light travels at 3.0 x 105 km/s. The sun is 1.5 x 108 km from Earth. How long does it take for the sun's light to reach Earth?
Answer:
It takes 8 minutes and 20 seconds for the light to travel this distance
Step-by-step explanation:
Velocity is calculated as:
V= d/t (1)
Where d is distance and t is time. As we want to find time t we must simplify (1) for t
t= d/V (2)
We replacethe values given:
t=d/V=1.5*10^8/3.0*10^5=5*10^3 = 500 seconds
As there are 60 seconds in a minute we find
minutes = 500/60 = 50/6 = 25/3 = 8 2/3 or 8 minutes 20 seconds

Which is the best estimate of 28 × 0 . 64 28×0.64?
A. 10
B. 15
C. 21
D. 28
Answer:
It is 15.
Step-by-step explanation:
Because the actual answer between 28 x 0.64 is 17.92.
The closest estimate for the multiplication of 28 by 0.64, is approximately 19 and given the options, 15 would be the best choice.
Explanation:The question is asking for the closest estimate for a multiplication problem, 28 times 0.64. We can convert the decimal 0.64 to a fraction which is approximately 2/3 (as 0.67 is closer to 0.64 than 0.5 - which would be 1/2). Hence, when multiplying 28 by 2/3, we get approximately 19.
Looking at the options given, 19 is not there. So, we select the nearest option to 19 which, in this case, it would be option B. 15.

How many solutions does the following equation have ?
In the equation 4(y - 30) =4y + 12, the correct option is no solution. Therefore, option A is correct.
What is an equation?Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation. For an unknown quantity represented by an unknown variable, equations are then solved to determine its value. It is clear that a statement is not even an equation if there is no "equal to" sign in it.
Let's solve the equation,
4(y - 30) =4y + 12
4y - 120 = 4y + 12
The value of 4y is got cancelled from both the sides, then the equation has no solution.

If g(x)= 2x-1, and h(x)= square root of x, find (goh)(9)
Answer:
The [tex](goh)(9)=5[/tex]
Step-by-step explanation:
We need to find out the [tex](goh)(9)[/tex]
Given:- [tex]g(x)=2x-1[/tex] and [tex]h(x)=\sqrt{x}[/tex]
First we need to find out the composition of (gof)(x)
Replace x in function g(x) with h(x) as;
[tex](goh)(x)=2(h(x))-1[/tex]
[tex](goh)(x)=2(\sqrt{x})-1[/tex]
Now put x=9 , in above to get the [tex](goh)(9)[/tex]
[tex](goh)(9)=2(\sqrt{9})-1[/tex]
[tex](goh)(9)=2(3)-1[/tex]
[tex](goh)(9)=6-1[/tex]
[tex](goh)(9)=5[/tex]
Therefore, [tex](goh)(9)=5[/tex]

Step-by-step explanation:
Greg builds a new pond which has a volume of 7.35 m3. It is 4.2 m long and 50 cm deep. What is the width of the pond?
volume = length x width x depth
50cm = 0.5 m
7.35 = 4.2 x 0.5 x X
7.35 = 2.1 x X
x = 7.35 / 2.1
x = 3.5
width = 3.5 meters
Answer: 3.5 meters
Step-by-step explanation:
Given : The volume of a new pond = [tex]7.35\ m^3[/tex]
The length of a new pond = 4.2 m
The depth of the pond = 50 cm =0.5 m
Let the width of the pond be 'w'.
The volume of cuboid is given by :_
[tex]V=l\times h\times w\\\\\Rightarrow\ 7.35=4.2\times0.5\times w\\\\\Rightarrow\ w=\dfrac{7.35}{0.5\times4.2}\Rightarrow\ w=3.5[/tex]
Hence, the width of the pond = 3.5 meters

Given : Jason draws a line in the sand at the beach.
The line is [tex]\dfrac{7}{8}[/tex] ft long.
He wants to divide the line into sections that are each [tex]\dfrac{1}{8}[/tex] ft long.
Then, the number of section will the line be divided into is given by using division operation:-
[tex]\dfrac{7}{8}\div\dfrac{1}{8}[/tex]
[tex]\dfrac{7}{8}\times8=7[/tex] [Change [tex]\dfrac{1}{8}[/tex] by its reciproval (8) to convert division operation into multiplication]
