Which inequality can be used to represent this scenario?
Mikael needs to rent a scooter to get to work. The scooter charges $1.85 to activate it and $0.50 per mile Mikael has a gift card for
$10 and he can not spend more on the scooter
O 10 < 0.502 +1.85
O 10 < 1.85.1 +0.50
O 10 > 1.852 +0.50
O 10 > 0.503 +1.85
Answer:
[tex]10 > 1.85 + 0.5m[/tex]
Step-by-step explanation:
Price of the scooter:
Fixed price of $1.85 to activate plus $0.50 for each mile. This situation can be represented by a linear function, and it is given by:
[tex]P(m) = 1.85 + 0.5m[/tex]
Mikael has a gift card for $10 and he can not spend more on the scooter.
The spendings have to be less than 10. So
[tex]10 > P(m)[/tex]
[tex]10 > 1.85 + 0.5m[/tex]
If a vertical angle has 74 degree and also opposite angle is 2x degree ,what is value of x?
Answer:
x = 37
Step-by-step explanation:
Well if you didn't know vertical angles are congruent ( or equal to each other )
Which means that 74 = 2x
If we want to find the value of x, then we need to get rid of the "2" on 2x
To do so we can divide each side by 2
74 / 2 = 37
2x / 2 = x
we would be left with x = 37

A block of hay with dimensions 100 cm × 40 cm × 30cm is given .And we need to find the volume of the hay . The hay is in the form of cuboid .We know that the volume of a cuboid is ,
[tex]:\implies[/tex] Volume = l × b × h
[tex]:\implies[/tex] Volume = 100cm*40cm*30cm
[tex]:\implies[/tex] Volume = 1,20,000 cm³
Hence the correct option is B .These cones are similar. Find the surface
area of the smaller cone. Round to the
nearest tenth.
2 cm
3 cm
Surface Area = [ ? ) cm2 Surface Area = 75 cm2
Helppppp plssss
Answer:
33.3 cm²
Step-by-step explanation:
Recall: Area Scale Factor = (Linear Scale Factor)²
Area scale factor = surface area of bigger cone/surface area of smaller cone
Let the surface area of the smaller cone be represented as x
Therefore,
Area scale factor = 75/x
Linear scale factor = radius of bigger cone/radius of smaller cone = 3/2
Thus:
75/x = (3/2)²
75/x = 9/4
Cross multiply
x*9 = 75*4
9x = 300
Divide both sides by 9
x = 300/9
x = 33.3 cm² (nearest tenth)
Find the measure of 0. Round answer to the nearest tenth. Pleas help
Answer:
[tex]\theta=36.43^{\circ}[/tex]
Step-by-step explanation:
Given that,
Base = 42
Perpendicular height = 31
We need to find the value of [tex]\theta[/tex]. It can be calculated using trigonometry as follows :
[tex]\tan\theta=\dfrac{P}{B}\\\\\theta=\tan^{-1}(\dfrac{P}{B})[/tex]
Put all the values,
[tex]\theta=\tan^{-1}(\dfrac{31}{42})\\\\\theta=36.43^{\circ}[/tex]
So, the value of [tex]\theta=36.43^{\circ}[/tex].

A multiple choice test contains questions
with four options each: A, B, C, or D. If
Natalie randomly guesses on the last three
questions, what is the probability that she
gets all three correct?
Answer:
Probability of getting all three correct answer = [tex]\frac{1}{64}[/tex]
Step-by-step explanation:
Given - A multiple choice test contains questions with four options each: A, B, C, or D. If Natalie randomly guesses on the last three questions.
To find - what is the probability that she gets all three correct.
Proof -
Given that, question has 4 options.
And 1 option can be correct,
Let
x be that Natalie gives correct answer.
So,
Probability of getting, correct answer, P(x) = [tex]\frac{1}{4}[/tex]
So,
Probability of getting, incorrect answer, P(x') = 1 - [tex]\frac{1}{4}[/tex] = [tex]\frac{3}{4}[/tex]
Now,
Given that, she guess the 3 questions.
All correct means,
first, second, third question answer is correct.
So,
Probability of getting all three correct answer = [tex]\frac{1}{4}[/tex]×[tex]\frac{1}{4}[/tex]×[tex]\frac{1}{4}[/tex] = [tex]\frac{1}{64}[/tex]

The weights of cans of Ocean brand tuna are supposed to have a net weight of 6 ounces. The manufacturer tells you that the net weight is actually a Normal random variable with a mean of 6.03 ounces and a standard deviation of 0.22 ounces. Suppose that you draw a random sample of 40 cans.
Part i) Using the information about the distribution of the net weight given by the manufacturer, find the probability that the mean weight of the sample is less than 5.99 ounces. (Please carry answers to at least six decimal places in intermediate steps. Give your final answer to the nearest three decimal places. Use Rcmdr for this question.)
Probability (as a value to 3 decimal places between 0 and 1 inclusive) ______
Part ii) Use normal approximation to find the probability that more than 56% of the sampled cans are overweight, i.e. the net weight exceeds 6 ounces. (Please carry answers to at least six decimal places in intermediate steps. Give your final answer to the nearest three decimal places. Use Rcmdr for this question.)
Probability (as a value to 3 decimal places between 0 and 1 inclusive) _______
Answer:
Following are the solution to the given points:
Step-by-step explanation:
For point (i):
[tex]P(X < 5.99) = P(Z < (\frac{(5.99 - 6.03)}{\frac{0.22}{\sqrt{(40)}}})[/tex]
[tex]= P(Z < -1.15) \\\\= 0.125[/tex]
For point (ii):
[tex]P(X> 6) = P( Z > \frac{(6 - 6.03)}{(\frac{0.22}{\sqrt{(40)}})})[/tex]
[tex]= P(Z > -0.8624 ) \\\\ = 0.806\\\\\to n = 40 \\\\ \to p = 0.806\\\\\to 56\% = 0.56\times 40 = 22.4\\\\\to u = np = 40\times 0.806 = 32.24\\\\P(X > 22.4) = P(Z > \frac{(22.4 - 32.24)}{\sqrt{(40\times 0.806\\\times (1-0.806))}})[/tex]
[tex]= P(Z > -3.93 ) \\\\= 1[/tex]

solve the given system of equations 2x + 8y= 5 and 24x - 4y = -15
9514 1404 393
Answer:
(x, y) = (-1/2, 3/4)
Step-by-step explanation:
A graphing calculator does a nice job of finding the solution.
(x, y) = (-1/2, 3/4)
__
You can eliminate y by adding twice the second equation to the first.
(2x +8y) +2(24x -4y) = (5) +2(-15)
50x = -25
x = -1/2 . . . . . . divide by 50
__
24(-1/2) -4y = -15 . . . . .substitute for x in the second equation
-4y = -3 . . . . . . . . . add 12
y = 3/4 . . . . . . . . . divide by the coefficient of y
The solution is (x, y) = (-1/2, 3/4).

A system of equations is created by using the line represented by2x+4y=0And the line represented by the data in the table below
What is the X value of the solution to the system if x -1 and y is 8
Answer:
x = 2
Step-by-step explanation:
From the data, we obtain the slope :
-1, 8 ; 3, - 4
Slope = Rise / run
Rise = y2 - y1 = (-4 - 8) = - 12
Run = x2 - x1 = (3 - (-1)) = 4
Slope, m = - 12 / 4 = - 3
Recall:
Equation of line :
y - y1 = m(x - x1)
y - 8 = - 3(x + 1)
y - 8 = - 3x - 3
y = - 3x - 3 + 8
y = - 3x + 5
Substituting y = - 3x + 5 into the equation 2x+4y= 0
2x + 4(-3x + 5) = 0
2x - 12x + 20 = 0
-10x = - 20
x = 2
