Benito earns $250 per week giving surfing lessons plus $75 for each surfboard he sells. If Benito wants to earn at least $500 this week, which inequality could be solved to find x, the number of surfboards he needs to sell?
Group of answer choices
250 x +75< equal to 500
250 +75x> equal to 500
250+75x equal to 500
Multiply 75 by the number of surfboards sold to get 75x add that to what he makes giving lessons:
250 + 75x
He wants to earn at least 500 so the equation has to be greater than or equal to 500:
Answer: 250 + 75x > equal to 500
The sanitation department calculated that last year each city resident produced approximately 1. 643 × 103 pounds of garbage. There are 2. 61 × 105 people living in the city. How much garbage did the city sanitation department collect last year? 4. 2882 pounds 428. 820 pounds 428,820 pounds 428,820,000 pounds.
Answer:
(d) 428,820,000 pounds of garbage
Step-by-step explanation:
Your calculator or spreadsheet can give you the product of two numbers expressed in scientific notation.
(1.643×10^3 lb/resident) × (2.61×10^5 residents) = 4.28823×10^(3+5) lb
≈ 428.82×10^6 lb
= 428,820,000 lb . . . of garbage

a player must be paid at least $20,000
and that the total of all players' salaries
for each team cannot exceed $600,000.
What is the maximum possible salary, in
dollars, for a single player?
The maximum possible salary for each player is calculated as $27,272.72
Data;
Numbers of Players in each team = 22Minimum allowed salary = $20,000Maximum allowed salary for the team = $600,000Maximum Possible SalaryThe maximum possible salary for a single player in each team can be calculated when we divide the total maximum allowed salary for the team by the total numbers of players. This would put all the players on an even pay or equal pay.
Let the maximum possible allowed salary be represented by x
[tex]x = \frac{60000}{22} \\x= 27,272.72[/tex]

Last week the price of gas was $2. 25. This week, the price has decreased by 15%. What is the price of gas this week
Answer:
$ 1.9125
Step-by-step explanation:
price of gas last week= $2.25
15% of $2.25 = 15/100 × 2.25
= $0.3375
since the price of the gas decreased by 15% this week, the new price will be 2.25- 0.3373 =$1.9125.

10. B, C, E
Step-by-step explanation:
The growth factor (or factor of decrease) for a time period will be found by taking the ratio of the value at the end of the time period to the beginning value.
9a.The population is 320 after 1 year. It started at 400 at the beginning of the year, so the factor of decrease is 320/400 = 0.80.
b.The exponential function can be written as ...
f(t) = a·b^t . . . . . where 'a' is the initial population, and 'b' is the factor of decrease
The initial population is shown on the graph as 400; the factor of decrease is what we just computed.
f(t) = 400(0.80^t)

Given sinx=0. 3, what is cosx? Enter your answer as a decimal in the box. Round only your final answer to the nearest hundredth.
Trigonometric function gives the ratio of different sides of a right-angle triangle. The value of Cos(x), if the value of Sin(x) is 0.3 is 0.954.
What are Trigonometric functions?The trigonometric function gives the ratio of different sides of a right-angle triangle.
[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}\\\\\\Cosec \theta=\dfrac{Hypotenuse}{Perpendicular}\\\\\\Sec \theta=\dfrac{Hypotenuse}{Base}\\\\\\Cot \theta=\dfrac{Base}{Perpendicular}\\\\\\[/tex]
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.
As the value of sin(x) is given to us, therefore, we will find the value of x firstly,
[tex]\rm Sin(x)=0.3\\\\x = Sin^{-1}\ 0.3\\\\x = 17.4576[/tex]
Therefore, the value of cos(x) can be written as,
[tex]\rm Cos(x)\\\\= Cos(17.4576)\\\\= 0.9539\approx 0.954[/tex]
We can also use the trigonometric property, therefore,
[tex]\rm (Sin\ x)^2 +(Cos\ x)^2=1\\\\0.3^2 + (Cos\ x)^2 = 1\\\\Cos(x) = \sqrt{1-0.3^2}\\\\Cos(x)=0.954[/tex]
Hence, the value of Cos(x), if the value of Sin(x) is 0.3 is 0.954.

Answer: I Think It Is Greater Than Or Equal To -9
Step-by-step explanation: The given function is:
f(x)x^2+2x-8
We complete the square to write this function in the form:
f(x)=a(x-h)^2+k
We add and subtract the square of half the coefficient of x.
f(x)=x^2+2x+1^2-1^2-8
f(x)=(x=1)^2-9
The vertex of this function is (h,k) which is (-1,-9)
The equation of axis of symmetry is x=h
But h=-1, hence the axis of symmetry isx=-1
To find the x-intercepts, we put f(x)=0
(x+1)^2-9=0
(x+1)^2=9
x+1=the square root of 9
x=-4, 2
The x-intercepts are:(
-4,0) and (2,0)
The given function is a polynomial function, the domain is all real numbers
The function has a minimum value of y=-9.
Therefore the range is y|y is greater that or less than -9
Find the distance between the two points in simplest radical
form.
(3,0) and (-3, -8)
Answer: 10 units
Step-by-step explanation:
We will use the distance formula and solve. Let (3, 0) be point 1 and (-3, -8) be point 2.
d = [tex]\sqrt{(x_{2} -x_{1})^{2} +(y_{2} -y_{1} )^{2} }[/tex]
d = [tex]\sqrt{(-3-3)^{2} +(-8-0)^{2} }[/tex]
d = [tex]\sqrt{(-6)^{2} +(-8)^{2} }[/tex]
d = [tex]\sqrt{36 +64}[/tex]
d = [tex]\sqrt{100}[/tex]
d = 10
The distance between the two points given is 10 units.
