Answer:
Easton entered in 25 shows last year.
Step-by-step explanation:
Given that Easton won best in show in 60% of the shows I have entered, to determine how many show was Easton entered if he won best in show 15 times last year, the following calculation must be performed:
60 = 15
100 = X
(100 x 15) / 60 = X
1,500 / 60 = X
25 = X
Therefore, Easton entered in 25 shows last year.
Round your answer to the nearest hundredth.

Sami made 23,400 last year in income from his job. He worked 30 hours per week and worked all 52 weeks of the year. What was his hourly pay rate?
Answer:
$15 per hour
Step-by-step explanation:
30 hours per week x 52 weeks in a year = 1560 hours per year
23,400 / 1560 = $15 per hour

Answer:
y = -2/3 x + 6
Step-by-step explanation:
Using the coordinates (1, 16/3) and (3,4)
Slope m = 4-16/3/3-1
Slope m = -4/3 * 1/2
Slope m = -2/3
For the y-intercept
Substitute (3,4) and m = -2/3 into y =mx+b
4 = -2/3(3) + b
4 = -2 + b
b = 4 + 2
b = 6
Get the required equaton;
Recall that y = mx+b
y = -2/3 x + 6

Answer:
2 bicycles
Step-by-step explanation:
let no. of bicycles be xno.of tricycles = (6 -x)as there were 5 bicycles and tricycles
now,
a bicycle has 2 wheels a tricycle has 3 wheelstotal no.of wheels = 16
2x + 3(6 - x) = 16
2x + 18 - 3x= 16
2 - x = 0
2 = x
therefore, there are 2 bicycles.
Olivia bought a notebook for $12.50 and 9 pens. If her total was $43.73, how
much was each pen?
Help quick pls
Answer:
$3.47
the cost of each pen is $3.47
Step-by-step explanation:
subtract the price of notebook from total price
43.73 - 12.50
= 31.23
divide total from number of pens
31.23 / 9
= 3.47
Write the meaning of each algebraic expression. Then, evaluate the algebraic expression for the given value.

In mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number). For example, 3x2 − 2xy + c is an algebraic expression.
5x−4x=3
Step 1: Simplify both sides of the equation.
5x−4x=3

Consider a triangle A BC like the one below. Suppose that A = 100°, b =51, and c= 45. (The figure is not drawn to scale.) Solve the triangle. Carry your intermediate computations to at least four decimal places, and round your answers to the nearest tenth. If there is more than one solution, use the button labeled "or".
Answer:
[tex]A = 100^o[/tex]
[tex]B = 43.0^o[/tex]
[tex]C =37.0^o[/tex]
Step-by-step explanation:
Given
[tex]A = 100^o[/tex]
[tex]b = 51[/tex]
[tex]c =45[/tex]
Required
Complete the triangle (See attachment)
First, calculate side a using cosine's equation
[tex]a^2 = b^2 + c^2 -2bc \cos A[/tex]
[tex]a^2 = 51^2 + 45^2 -2*51*45 \cos (100^o)[/tex]
[tex]a^2 = 4626 -4590 *-0.1736[/tex]
[tex]a^2 = 4626+ 796.8[/tex]
[tex]a^2 = 5422.8240[/tex]
Take square roots
[tex]a = 73.6398[/tex]
The measure of B and C can then be calculated using sine's equation
[tex]\frac{a}{\sin A} =\frac{b}{\sin B} =\frac{c}{\sin C}[/tex]
So:
[tex]\frac{73.6398}{\sin (100)} =\frac{51}{\sin B}[/tex]
[tex]\frac{73.6398}{0.9848} =\frac{51}{\sin B}[/tex]
Cross multiply
[tex]\sin B * 73.6398 = 51 * 0.9848[/tex]
[tex]\sin B * 73.6398 = 50.2248[/tex]
Solve for sin B
[tex]\sin B = \frac{50.2248}{73.6398}[/tex]
[tex]\sin B = 0.6820[/tex]
Take arc sin of both sides
[tex]B = \sin^{-1}(0.6820)[/tex]
[tex]B = 43.0^o[/tex]
To calculate C, we make use of:
[tex]A + B + C = 180^o[/tex] --- angles in a triangle
[tex]100 + 43 + C = 180[/tex]
[tex]143 + C = 180[/tex]
Collect like terms
[tex]C =180-143[/tex]
[tex]C =37.0^o[/tex]

Answer:
3:1
Step-by-step explanation:
If you look at the sides, they all have the same factor of three, and dividing by three gets you to the smaller rectangular prism.
in a school , 4/9 of the students are boys and number of girls is 90 . find the number of boys in school
4/9 of the students are boys thus 5/9 students are girls.
Let " x " be the number of all students.
So we have :
5/9 × x = 90
Multiply both sides by 9/5
5/9 × 9/5 × x = 90 × 9/5
1 × x = 9 × 9 × 10 × 1/5
x = 81 × 2
x = 162
_______________________________
number of boys = 4/9 × x
n o boys = 4/9 × 162
n o boys = 162/9 × 4
n o boys = 18 × 4
n o boys = 72

Alex is a writer who writes poems and short stories. For an upcoming writer's workshop Alex wants to write some new works. He needs to determine how many poems and short stories he will have ready for the workshop. Alex figures that each poem will take him 30 hours and each short story will take him 70 hours. For the workshop Alex wants to have at least 4 poems and 3 short stories to display. If Alex has 840 hours of work time available, what solution represents the maximum number of works that he could write while staying in his time budget
Answer:
The maximum number of works that he can write while staying in his time budget is 24.
21 poems and 3 short stories
Step-by-step explanation:
In order to solve this problem we must first determine what our variables are. In this case it's the number of poems and short stories he can write.
p = # of poems
s = # of short stories
Next, we must build our objective function which will represent the total number of works he can write.
N=p+s
where N is the number of works.
Next, we must write the constrains based on the information provided by the problem.
The problem tells us that it takes him 30 hours to write a poem and 70 hours to write a short story and that he has 840 hours available to write them, so that constrain will be the following:
[tex]30p+70s \leq 840[/tex]
it also tells us that he wants to write at least 4 poems and 3 short stories so there we have our other two constrains.
[tex]p \geq 4[/tex]
[tex]s \geq 3 [/tex]
once we got our constrains we can go ahead and graph them to see how they will behave. (See attached picture)
In the graph p is the horizontal axis and s is the vertical axis.
On the graph we can see a polygon that is formed by the restriction. The vertices of the polygon will represent the optimal conditions for this linear programming problem. There are three optimal solutions there, so we need to test them to see which will return the greatest number of works he can write while keeping the given conditions.
Option 1:
4 poems and 3 short stories
N=4+3
N= 7 works
Option 2:
4 poems and 10 short stories
N=4+10
N=14 works
Option 3:
21 poems and 3 short stories
N=21+3
N=24 works
So the optimal solution will be given by option 3 with 21 poems and 3 short stories.
