Jazlyn ate 9.1 quarts of ice cream last summer. Her brother, Jazel, ate 45.5 quarts of ice cream last summer. How many times more quarts of ice cream did Jazel eat than Jazlyn?

Answers

Answer:5 times more

Step-by-step explanation:

9.1 x 5 is 45.5

0.1 x 5 = 0.5

9.0 x 5= 45.0

0.5 + 45.0 = 45.5

Which is greater? 3/50 or 0.74

A university president believes that over the past few years, the mean age of students attending his university has decreased. To test this hypothesis, a study is conducted in which the age of 150 students who have been randomly sampled from the student body is measured. The mean age is 21.5 years. A complete census taken at the university a few years prior to the study showed a mean age of 23.5 years, with a standard deviation of 8.5. Test using a 1% level of significance.

50 points! Tell whether the orthocenter is inside, on, or outside the triangle. Then find the coordinates of the orthocenter.
Q(-1, 5), R(4, 3), S(-1, -2)

Answers

Answer:

(1,3) is inside the triangle

Step-by-step explanation:

Orthocenter is the intersection of altitudes.

We'll calculate the slopes of the two sides and their altitudes ad find the intersection.

Side QRm = (3 - 5)/(4 - (-1)) = -2/5

Perpendicular slope:

-1/m = 5/2

Perpendicular line passes through S(-1, -2):

y - (-2) = 5/2(x - (-1)) ⇒ y = 5/2x + 1/2Side RSm = (-2 - 3)/(-1 -4) = -5/-5 = 1

Perpendicular slope:

-1/m = -1/1 = -1

Perpendicular line passes through Q(-1, 5):

y - 5 = -(x - (-1)) ⇒ y = -x + 4

The intersection of the two lines is the orthocenter.

Solve the system of equations to get the coordinates of the orthocenter:

5/2x + 1/2 = x + 45x + 1 = -2x + 87x = 7x = 1

Find y-coordinate:

y = -1 + 4 = 3

The orthocenter is (1, 3)

If we plot the points, we'll see it is inside the triangle

Steve started with $250 and spent $20 per week. Chelsea started with nothing but saved $30 per week. Use x for time and y for savings.

Write an equation to represent Steve's situation.

Answers

Answer:

[tex]250 - 20x=y[/tex]

Step-by-step explanation:

As per the given problem, Steve starts with $250, and spent $20 a week, the problem mentions nothing about Steve's savings, therefore, one can assume that they didn't save anything. As the problem requests, parameter ([tex]x[/tex]) will be used for the time, and ([tex]y[/tex]) for the savings.

Steve's saving would be equal to his initial value, minus his expense, in essence;

[tex]250 - 20x=y[/tex]

The initial value, minus the amount spend per week multiplied by the week number will equal the savings left.

Answer:

y=250-(20x)

What is the answer 3x-5=2x-1

Answers

Answer:

x=4

Step-by-step explanation:

Answer:

x = 4

Step-by-step explanation:

3x - 5 = 2x -1

Add 5 to both sides

3x - 5 + 5 = 2x - 1 + 5

           3x = 2x + 4

Subtract 2x form both Sides

3x - 2x  = 2x - 2x + 4

       x = 4

Candice is decorating a ballroom ceiling with garland. The width of the rectangular ceiling is 30 meters and the diagonal distance from one corner to the opposite corner is 34 meters. How much garland will Candice need for the length of the ceiling

Answers

Answer:

16 meters

Step-by-step explanation:

Candice is decorating a ballroom ceiling with garland. The width of the rectangular ceiling is 30 meters and the diagonal distance from one corner to the opposite corner is 34 meters. How much garland will Candice need for the length of the ceiling

The formula to solve for the above question is:

Diagonal² = Width² + Length²

34² = 30² + L²

Collect like terms

L² = 34² - 30²

L = √34² - 30²

L = √(256)

L = 16 meters

Therefore, the length of the ceiling is 16 meters

Answer: (-1,1/8)

Step-by-step explanation:

Coordinates are given in (x,y) format. The x axis runs left to right and the y axis runs up and down.

Point P is on -1 of the x axis and appears to be between 0 and .25 on the y axis. This would be half of .25. .25 is 1/4 as a fraction. Half of 1/4 is 1/8. So the coordinates for point P are (-1,1/8)

a sandwich store charges $10 delivery fee and $4.50
b. what is the total cost for x sandwiches ?

Answers

Answer:

Step-by-step explanation:

a sandwich store charges $10 delivery fee and $4.50

b. what is the total cost for x sandwiches ?

           total cost equals the cost of the sandwiches plus the delivery fee

one sandwich cost $4.50    

x number of sandwiches cost        x times $4.50   or $4.50(x)

delivery fee = $10

total cost equals the cost of the sandwiches plus the delivery fee

                            total cost  =        $4.50(x)      +               $10

total cost  =  $4.50(x)  +  $10

Answers

x= 240/7

So we know that according to the law of multiplying exponents that when multiplying them, you are just adding them together

With that in mind, x/6+x/8=10

From here, we can just solve for x!

Multiply both sides by 24

4x+3x=240

Add the x’s

7x=240

Anddddd divide both sides by 7

x=240/7

Remember, you can always double check your answer by plugging in your answer into your original equation! :)
