Julian is working two summer jobs, making $8 per hour washing cars and making
$13 per hour tutoring. In a given week, he can work a maximum of 13 total hours and
must earn no less than $130. If a represents the number of hours washing cars and y
represents the number of hours tutoring, write and solve a system of inequalities
graphically and determine one possible solution.
Answer:
Jacob should work minimum of 14 hours washings cars to meet his requirement.
Step-by-step explanation:
Let the number of hours of washing cars be 'x'.
Let the number of hours of landscaping be 'y'.
Given:
Cost for Per hour for washing cars = $10
Cost for per hour Landscaping = $8
Total number of hours of working
Amount to be earned this weekend
So we can say that;
Also,
Amount to be earned this weekend should be greater than or equal to sum of Cost for Per hour for washing cars multiplied by number of hours of washing cars and Cost for per hour Landscaping multiplied by number of hours of landscaping.
framing in equation form we get;
Now Number of hours he worked for landscaping
So we get;
Subtracting both side by 32 we get;
Dividing both side by 10.
Hence Jacob should work minimum of 14 hours washings cars to meet his requirement.

Select all of the sets of measurements that can form a triangle.
35°, 15, 130°
90°, 3 inches, 7 inches
70°, 70°, 70°
17 inches, 8 inches, 2 inches
5 inches, 6 inches, 7 inches
The sets of measurements that can form a triangle are:
90°, 3 inches, 7 inches
5 inches, 6 inches, 7 inches.
To determine which sets of measurements can form a triangle, we need to apply the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
Let's analyze each set of measurements:
35°, 15, 130°:
This set cannot form a triangle because the angles are not appropriate. The sum of the angles in a triangle must be 180°, but the given angles add up to 180° - (35° + 130°) = 15°, which is not possible.
90°, 3 inches, 7 inches:
This set can form a triangle. The sum of the two shorter sides (3 inches + 7 inches) is greater than the longest side (10 inches), satisfying the triangle inequality theorem.
70°, 70°, 70°:
This set cannot form a triangle because the angles are not appropriate. The sum of the angles in a triangle must be 180°, but the given angles add up to 210°, which is greater than 180°.
17 inches, 8 inches, 2 inches:
This set cannot form a triangle. The sum of the two shorter sides (2 inches + 8 inches) is less than the longest side (17 inches), violating the triangle inequality theorem.
5 inches, 6 inches, 7 inches:
This set can form a triangle. The sum of the two shorter sides (5 inches + 6 inches) is greater than the longest side (7 inches), satisfying the triangle inequality theorem.
Therefore, the sets of measurements that can form a triangle are:
90°, 3 inches, 7 inches
5 inches, 6 inches, 7 inches.

The value of the exponential equation is A = ( 1/343 ) = ( 1/7 )³
What are the laws of exponents?When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.
The different Laws of exponents are:
mᵃ×mᵇ = mᵃ⁺ᵇ
mᵃ / mᵇ = mᵃ⁻ᵇ
( mᵃ )ᵇ = mᵃᵇ
mᵃ / nᵃ = ( m / n )ᵃ
m⁰ = 1
m⁻ᵃ = ( 1 / mᵃ )
Given data ,
Let the exponential equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
A = ( 1/7 ) x ( 1/7 ) x ( 1/7 ) be equation (1)
On simplifying the equation , we get
A = ( 1/7 )³

The group wants to travel from its current location on the map to the South Pole, and then directly back to base camp, passing through their current location. There are 5 people in the group and they expect to travel an average of 10 miles per day. Remember that each person needs 6000 calories per day. Based on your response to item 3, what is the minimum number of calories the group is expected to consume during the entire trip?
the answer to number 3 is 75 miiles
The minimum number of calories the group is expected to consume during the entire trip from current location to southpole and back to camp is 375 kilo calories.
What is Pythagoras theorem?Pythagoras theorem says that in a right angle triangle the square of hypotenuse side is equal to the sum of square of other two legs of right angle triangle.
There are total 5 miles in one block and current location to the South Pole there are 5 blocks on map. Thus, the total distance from current location to the South Pole is,
[tex]x=5\times5\\x=25\rm\; miles[/tex]
There are total 12 blocks from current location to the camp on map. Thus, the total distance from current location to the camp is,
[tex]y=12\times5\\y=60\rm\; miles[/tex]
The shortest distance from South Pole to camp is,
[tex]z=\sqrt{25^2+60^2}\\z=\sqrt{4225}\\z=65\rm\; miles[/tex]
Total distance group travel from if it wants to travel from its current location on the map to the South Pole, and then directly back to base camp, passing through their current location is,
[tex]n=65+60\\n=125\rm\; miles[/tex]
The group travel an average of 10 miles per day. Thus, number of days to cover distance,
[tex]\dfrac{125}{10}=12.5\rm\; days[/tex]
There are total 5 people in group and they consume each person needs 6000 calories per day. Thus, total calories,
[tex]C=12.5\times6000\times5\\C=375000 \rm\;C\\C=375 \rm\; kC[/tex]
Thus, the minimum number of calories the group is expected to consume during the entire trip from current location to southpole and back to camp is 375 kilo calories.

The spinner is equally likely to land on any of the six sections. a spinner contains 6 equal sections: 1, 2, 3, 4, 5, 6. sections 1, 3, and 5 are shaded. the spinner is pointing at number 6. what is the probability that the spinner will land on a number greater than 4 or on a shaded section? two-ninths one-half two-thirds five-sixths
The probability that the spinner will land on a number greater than 4 or on a shaded section is five-sixt
What is probability?Probability is the likelihood or chance that an event will occur. Mathematically;
Probability = Expected/Total
If the spinner is spinned, the total outcome is 1/6
Pr(greater than 4) = 2/6 = 1/3
Pr(shaded section) = 3/6 = 1/2
Pr(number greater than 4 or on a shaded section) = 1/3 + 1/2
Pr(number greater than 4 or on a shaded section) = 5/6
Hence the probability that the spinner will land on a number greater than 4 or on a shaded section is five-sixths

Answer:

The answer is that 50% of the sweaters cost $50 or less.
What is a box plot?To determine the fraction of sweaters that cost $50 or less, we need to look at the box plot and identify the range of prices that fall within that category.
Looking at the box plot, we can see that the box extends from $40 to $60, which means that 50% of the sweaters sold were priced between $40 and $60. Additionally, we can see that the left whisker of the box plot extends down to $30, which means that some sweaters were sold for less than $40.
Therefore, to find the fraction of sweaters that cost $50 or less, we need to calculate the portion of the box plot that falls below $50.
From the box plot, we can see that the distance between $40 and $50 is half of the total distance of the box or 25%. And the distance between $30 and $40 is also 25%. Therefore, the total fraction of sweaters that cost $50 or less is 25% + 25% = 50%.
So, the answer is that 50% of the sweaters cost $50 or less.

Answer:
The time it takes the ball to hit the ground is 3.05secs
step - by - step explanation:
In order to find height from where ball is dropped, you have to find height or h(t) when time or t is zero.So plug in t=0 into your quadratic equation:h(0) = -16.1(0^2) + 150h(0) = 0 +150h(0) = 150 ft is the height from where ball is dropped. When ball hits the ground, the height is zero. So plug in h(t) = 0 and solve for t.0 = -16.1t^2 + 15016.1 t^2 = 150t^2 = 150/16.1t = sqrt(150/16.1)t = ± 3.05Since time cannot be negative, your answer is positive solution i.e. t = 3.05
