divide 143.00 by 11.00
143/11 = 13
Answer is 2. 13.0 hours
Answer:
Step-by-step explanation:
Byron earns $11.00 per hour.
Lets say he works for x hours
for x hour Byron earn =11x
It is given that
Byron have to work to earn= $143.00
so
11x= 143
x=143/11
x=13
so He must work for 13.0 hours .

Write in slope-intercept form of the equation of the line through the given point. Through: (-3,-3) and (4,0)
Answer:
y = 3/7 x - 12/7
Step-by-step explanation:
The slope is (0+3)/(4+3) = 3/7
So, now you have a point and a slope, so use the point-slope form. That gives you
y-0 = 3/7 (x-4)
Now just rearrange to slope-intercept form.
y = 3/7 x - 12/7

How do you Solve by factoring
Final answer:
To solve an equation by factoring, find the factors, set them equal to zero, and solve for the variable.
Explanation:
To solve an equation by factoring, you need to find the factors of the equation and set each factor equal to zero. Then, solve each equation separately to find the values of the unknown variable. Let's take an example:
If we have the equation [tex]x^2 - 5x + 6 = 0[/tex]:
Factor the quadratic expression: (x - 2)(x - 3) = 0Set each factor equal to zero and solve: x - 2 = 0 and x - 3 = 0solve each equation separately to find the values of x: x = 2 and x = 3This method of factoring and setting each factor equal to zero is a systematic approach to solving quadratic equations, providing a structured way to identify the solutions for the unknown variable. The application of this technique is fundamental in algebra, enabling the efficient determination of roots in quadratic expressions and contributing to a comprehensive understanding of solving equations.

You and your friend are buying throw blankets with your names embroidered on them.The cost of the throw blanket is x dollars and the cost of each embroidered letter is y dollars.Your name has 6 letters and the total cost is $29.Your friend’s name has 3 letters and the total cost is $24.50.Find the cost of the throw blanket and the cost of each embroidered letter.
Answer:
Throw Blanket : $20
Embroidered Letter: $1.50
Step-by-step explanation:
Create a set of equations to solve this problem, where x is cost of throw blanket and y is cost of single embroidered letter.
My name:
[tex]x+6y=29\\x=29-6y[/tex]
Friend's name:
[tex]x+3y=24[/tex]
Substituting x into friend's name equation:
[tex](29-6y)+3y=24.5\\3y-6y=24.5-29\\-3y=-4.5\\y=1.5[/tex]
Substituting y into equation for x:
[tex]x=29-6(1.5)\\x=29-9\\x=20[/tex]

In the figure, AB||CB. If CD:BA = 6:5 and the area of CED is 288, find the area of BEA
Answer:
The area of BEA is 200 square units.
Step-by-step explanation:
Given information: AB||CD and CD:BA = 6:5.
Let the length of sides CD and BA are 6x and 5x respectively.
If a transversal line intersect two parallel lines, then the alternative interior angles are equal.
[tex]\angle EAB=\angle EDC[/tex] (Alternate interior angles)
[tex]\angle EBA=\angle ECD[/tex] (Alternate interior angles)
[tex]\angle AEB=\angle DEC[/tex] (Vertically opposite angles)
By AAA property of similarity,
[tex]\triangle ABE\sim \triangle DEC[/tex]
The area of two similar triangles is proportional to the square of their corresponding sides.
[tex]\frac{Area(CED)}{Area(BEA)}=\frac{CD^2}{BA^2}[/tex]
[tex]\frac{288}{Area(BEA)}=\frac{(6x)^2}{(5x)^2}[/tex]
[tex]\frac{288}{Area(BEA)}=\frac{36x^2}{25x^2}[/tex]
[tex]\frac{288}{Area(BEA)}=\frac{36}{25}[/tex]
[tex]288\times 25=36\times Area(BEA)[/tex]
[tex]7200=36\times Area(BEA)[/tex]
Divide both sides by 36.
[tex]200=Area(BEA)[/tex]
Therefore the area of BEA is 200 square units.
Coach Stevens needs to purchase sprinklers to water the baseball field. The standard distance between bases is 90 feet and the infield is a perfect square.
Coach Stevens found one sprinkler that sprays a maximum distance of 50 feet.
If Coach Stevens placed the sprinkler on the pitcher's mound, would the water spray so that the entire infield was watered? Justify your response.
Answer:
So, if coach Stevens places as sprinkler of maximum distance 50 ft, he won't be able to cover the entire infield.
Step-by-step explanation:
Consider the infield as a polygon ABCDE.
It is given that each side AB, BC, CD, and DA is of length 90ft. It is also given that the infield is a perfect square.
Thus, the area of the square ABCD = 8100 ft.
Now consider the triangle BCD. Because of symmetry, the area of this triangle equals half the area of the square. Again, because of symmetry, the length of the base BD equals twice the length of the height EC.
Thus from to the formula of area of the triangle:
base × height = 4050 base × height = 8100 2(height) × height= 8100 height63.64 ft

Which exponential function goes through the points (1, 8) and (4, 512)?
f(x) = 4(2)^x
f(x) = 8(2)^-x
f(x) = 4(4)^-x
f(x) = 2(4)^x
Answer:
Therefore, the correct option is: (C.) [tex]\( f(x) = 2 \cdot 4^x \)[/tex]
Explanation:
To determine the exponential function that passes through the given points, we can use the general form of an exponential function:
[tex]\[ f(x) = a \cdot b^x \][/tex]
Where:
[tex]\( a \)[/tex] is the initial value or the value of the function when [tex]\( x = 0 \).[/tex]
[tex]\( b \)[/tex] is the base of the exponential function.
Given the points [tex]\((1, 8)\) and \((4, 512)\)[/tex], we can substitute these coordinates into the general form and solve for [tex]\( a \) and \( b \).[/tex]
Using the point [tex]\((1, 8)\):[/tex]
[tex]\[ 8 = a \cdot b^1 \][/tex]
[tex]\[ 8 = a \cdot b \][/tex]
Using the point [tex]\((4, 512)\):[/tex]
[tex]\[ 512 = a \cdot b^4 \][/tex]
We can divide the equation obtained from the second point by the equation obtained from the first point to eliminate [tex]\( a \)[/tex] and solve for [tex]\( b \):[/tex]
[tex]\[ \frac{512}{8} = \frac{a \cdot b^4}{a \cdot b} \][/tex]
[tex]\[ 64 = b^3 \][/tex]
Taking the cube root of both sides:
[tex]\[ b = 4 \][/tex]
Now that we have found the value of [tex]\( b \)[/tex], we can substitute it back into one of the equations to find \( a \). Let's use the first point [tex]\((1, 8)\):[/tex]
[tex]\[ 8 = a \cdot 4 \][/tex]
[tex]\[ a = 2 \][/tex]
So, the exponential function that passes through the points [tex]\((1, 8)\) and \((4, 512)\)[/tex] is:
[tex]\[ f(x) = 2 \cdot 4^x \][/tex]
What is the 4 digit number in which the first digit is one-fifth of the last, and the second and third digits are the last digit multiplied by 3?
State how many imaginary and real zeros the function has. f(x) = x3 + 5x2 - 28x - 32
All equation has always
even numbers of imaginary roots because they always come in pairs. Therefore
there must be either 2 imaginary roots, or zero.
To determine the types of roots, we could try synthetic
division by some of the factors of the number -32. The simplest factors are +1
or -1. Using this, we can quickly show that (x + 1) is a factor, and leaving
(x² + 4x - 32) as the remainder. This remainder equation then factorises to (x
- 4) (x + 8).
So to conclude there are three real zeros which are:
x = -1
x = 4
x = -8

in a 30-60-90 Blondie triangle the long leg is half the hypotenuse
A. always
B. sometimes
c never
Answer:
never
Step-by-step explanation:
In a 30 - 60 - 90 degree triangle , the common ratio is
1 : [tex]\sqrt{3}[/tex] : 2
Shorter leg that is opposite to 30 degree = 1
Longer leg that is opposite to 60 degree = [tex]\sqrt{3}[/tex]
Hypotenuse is opposite to 90 degree = 2
Shorter leg is half the length of the hypotenuse as per the ratio
Long leg is never the half of the hypotenuse
