Answer:
c=15+25x
Step-by-step explanation:
From the information given, you can say that the total amount Tom's Landscaping charges for a job would be equal to the flat fee plus the result of multiplying the charge per hour for the number of hours and this would be:
c=y+25x (1), where:
c is the total cost
y is the flat fee
x is the number of hours
Now, as you know that Tom charged a customer $90 for a job that required 3 hours, you can replace c with 90 and x with 3 and solve for y to find the flat fee:
90=y+25(3)
90=y+75
90-75=y
y=15
Finally, as you know that the flat fee is 15, you can replace this value in (1) to establish the equation that would calculate the total amount that Tom's Landscaping charges for a job that requires x hours of work:
c=15+25x

Answer: the answer is 73.5 but it is not here so I think 89 is the
Step-by-step explanation:
Answer:
The answer is 149
Step-by-step explanation:
So 2 oranges added up is 56 which is basically
x+x=56
2x=56
56/2=28
Each orange is worth 28
The 2 triangles multiplied are 81 which is
x*x=81
x^2=81
√81=9
Each watermelon Is worth 9
The 3 stars added up are
x+x+x=15
3x=15
15/3=5
Each star is worth 5
So the final equation if you plug in what we know
9+28*5
So orders of operations, (Parenthesis, exponents, etc.)
So multiplication is first
28*5=140
And add
140+9=149
So final answer 149
y=3/4x+1
y+1/4x+3
pls help solve for x and y
Answer:
x+y+3 or 1x+1y+3
Step-by-step explanation:
3/4x+1/4x+1y+3
3/4x+1/4x=1x
1x+1y+3
You can't do x+y+3 so it stays x+y+3. Hope this helps.
Slove using substitution
Y= 2x + 1
3x + y = 11 Step by step explanation
Answer: x = 2 and y = 5
Step-by-step explanation:
y = 2x + 1
3x + y = 11
Substitute
3x + (2x + 1) = 11
5x + 1 = 11
Subtract both sides by 1
5x = 10
Divide both sides by 5
x = 2
y = 2x + 1
Substitute
y = 2 (2) + 1
y = 4 + 1
y = 5
When a stepladder is placed as shown, is it possible for the lower ends of the ladder to be 12 feet apart? Explain
Answer:
No, with the guides in between the two ladders, it is not possible for the lower ends of the ladder to be up to 12 feet apart
Step-by-step explanation:
The given parameters are;
The length of two sides of the step ladder = 12 feet
The maximum value allowable for the included angle between the two 12 feet ladders = 58°
Therefore, the maximum value of the third side facing the included angle is given as follows;
let "a" represent the maximum value of the third side formed by the distance apart of the lower end of the ladder, by cosine rule, we have;
a² = 12² + 12² - 2 × 12 × 12 × cos(58°) = 135.383251901
∴ a = √(12² + 12² - 2 × 12 × 12 × cos(58°)) ≈ 11.64
The maximum value of the third side formed by the distance apart of the lower end of the ladder = a ≈ 11.64 feet < 12 feet
Therefore, it is not possible for the lower ends of the ladder to be up to 12 feet apart.

Step-by-step explanation:
A school is building a rectangular stage for its chorus. The stage must have a width of 4 feet. The area of the stage must be at most 24 square feet. (These are rules of the local fire department.) Write an inequality that describes the possible lengths (in feet) of the stage.
Answer: Length ≥ 6 feet
Step-by-step explanation:
The area of a rectangle= length × width
In this case, the width is 4 feet and the area of the stage must be at most 24 square feet.
The inequality that describes the possible lengths (in feet) of the stage would be:
Length × Width ≥ 24
Length × 4 ≥ 24
Length ≥ 24/4
Length ≥ 6
Therefore, the length must be at most 6 feet.

I need help lol haha hahahahahhahhahahhahahah
Answer:
y=3x+10
Step-by-step explanation:
When two lines are parallel they are going to have the same slope which is 3x. The only thing we need to find is the y intercept based on the point they say the equation passes. to do this you take away the y intercept of the equation that we have and replace x with -2 and the subtract 4 to the side with the y.. now we have 4-y=-6 Then we solve for y and get y=10 which is the y intercept of the equation that is parallel to y=3x=1 and it passes (-2,4) Therefore the answer is y=3x+10

The value of the expression (x³+16) ÷4 is equal to 12. The correct option is B.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the expression is (x³+16) ÷4. The value of x is equal to 2. The expression will be solved as below,
E = (x³+16) / 4
E = 2³ + 16 / 4
E = 8 + 16 / 4
E = 8 + 4
E = 12

OAB is the sector of a circle, centre 0, with radius 8 cm and sector angle 30°.
BC is perpendicular to OA.
Calculate the area of the region shaded on the diagram.
Answer:
[tex]2.9 cm^2[/tex]
Step-by-step explanation:
Given,
Angle of sector = 30°
Radius of circle, r = 8 cm
Area of the shaded region, A =?
The diagram is attached below.
Now,
Area of shaded region = Area of sector - Area of triangle
Area of triangle = [tex]\frac{1}{2}\times base \times height[/tex]
We know that,
[tex]\sin \theta = \dfrac{P}{H}[/tex]
[tex]\sin 30^\circ= \dfrac{P}{8}[/tex]
[tex]P = \dfrac{8}{2}[/tex]
[tex]P = 4\ cm[/tex]
And
[tex]\cos \theta =\dfrac{B}{H}[/tex]
[tex]\cos 30^\circ = \dfrac{B}{8}[/tex]
[tex]B = \dfrac{8\times \sqrt{3}}{2}[/tex]
[tex]B = 4\sqrt 3[/tex]
Area of sector = [tex]\dfrac{\theta}{360^\circ}\times \pi r^2[/tex]
Area of sector = [tex]\dfrac{30^\circ}{360^\circ}\times \pi \times 8^2[/tex]
= 16.75 cm^2
Area of triangle = [tex]\dfrac{1}{2} \times 4\sqrt 3 \times 4[/tex]
= 13.85 cm^2
Area of shaded region = 16.75 - 13.85
= [tex]2.9 cm^2[/tex]
