Jeremiah's ice cream was 23.9 ounces when he checked out at the store. He ate 11.38 ounces before leaving, how many ounces did he take home as leftovers?​

Answer: 55 degrees

Step-by-step explanation: 180-70-55=u

This answer is because the sum of all the angles is 180 degrees.

Answer:

u = 55°

Step-by-step explanation:

The sum of the internal angles of a triangle = 180°

Then:

70 + 55 + u = 180

125 + u = 180

u = 180 - 125

u = 55°

Answer: 59.02 square inches

Step-by-step explanation:

We can use the formulas for the volume and surface area of a sphere to solve this problem.

The formula for the volume of a sphere is:

V = (4/3)πr^3

Where V is the volume, r is the radius, and π is pi (approximately equal to 3.14159).

We know that the volume of the sphere is 33.51 cubic inches, so we can plug that in and solve for the radius:

33.51 = (4/3)πr^3

r^3 = (3/4) * (33.51/π)

r^3 = 10.56

r ≈ 2.17

Now that we know the radius is approximately 2.17 inches, we can use the formula for the surface area of a sphere to find the surface area:

A = 4πr^2

A = 4π(2.17)^2

A ≈ 59.02 square inches

Therefore, the surface area of the sphere is approximately 59.02 square inches.

Answer: To solve this problem, we can start by drawing a diagram of the two triangles and the line connecting their hypotenuses. Let's label the height of the first triangle as h1, the width of the second triangle as w2, and the slope of the line as m.

We know that the hypotenuse of a right triangle is always longer than either of its legs, so we can conclude that h1 < w2. We also know that the height of the second triangle is 12 units, so we can label that as h2 = 12.

Using the Pythagorean theorem, we can express the lengths of the hypotenuses in terms of their legs:

h1^2 + 3^2 = L^2, where L is the length of the first hypotenuse

w2^2 + 12^2 = L^2, where L is the length of the second hypotenuse

Setting these two expressions equal to each other, we can solve for h1 in terms of w2:

h1^2 + 3^2 = w2^2 + 12^2

h1^2 = w2^2 + 12^2 - 3^2

h1^2 = w2^2 + 141

h1 = sqrt(w2^2 + 141)

Now, we can use the fact that the hypotenuses lie on the same line to write an equation for that line:

y = mx + b

where b is the y-intercept of the line. Since the hypotenuses intersect the y-axis at the points (0,h1) and (0,12), we know that b = (h1 + 12)/2. Therefore, our equation becomes:

y = mx + (h1 + 12)/2

To find the slope of the line, we can use the fact that the rise (change in y) over run (change in x) is the same for both triangles. We can express this as:

(h1 - 12) / 3 = 12 / w2

Solving for h1 in terms of w2 and simplifying, we get:

h1 = (36/w2) + 12

Substituting this expression for h1 into our equation for the line, we get:

y = mx + ((36/w2) + 24)/2

y = mx + (18/w2) + 12

Comparing this to the general form of the equation for a line, y = mx + b, we see that the slope is simply:

m = 18/w2

Substituting w2 = 3 (since we were given that the width of the second triangle is 3 units), we get:

m = 18/3 = 6

Therefore, the slope of the line is 6.

Step-by-step explanation:

The linear function that represents the line is f(x) = -3x + 14

We can rewrite the point-slope equation y + 1 = -3(x - 5) in slope-intercept form, which has the general form of y = mx + b, where m is the slope and b is the y-intercept.

To do this, we first distribute the -3 on the right side of the equation:

y + 1 = -3x + 15

Then, we can isolate y by subtracting 1 from both sides:

y = -3x + 14

So the slope of the line is -3 and the y-intercept is 14. Therefore, the linear function that represents the line is:

f(x) = -3x + 14

Hence, the correct answer is f(x) = -3x + 14.

The height of the plane is about 3855 feet and the distance from the nearer end of the runway is about 13580 feet.

To find out the height of the plane and the distance of it from the nearer end of the runway, we have to use trigonometry.

Let's start by finding the height of the plane, h.

Using the angle of depression of 12.5 degrees, we can write this equation:

tan 12.5 = h/d

Where d is the distance from the nearer end of the runway. If we cross-multiply, we get:

d = h/tan 12.5

We can use the equation from the other angle of depression to eliminate the distance,

d.tan 17.0 = h/(d + 10,000)

By substituting the previous equation in for d, we get:

tan 17.0 = h/(h/tan 12.5 + 10,000)

Simplifying: tan 17.0 = h(tan 12.5)/(h/tan 12.5 + 10,000)

Multiplying both sides by h/tan 12.5 + 10,000:

tan 17.0 (h/tan 12.5 + 10,000) = h tan 12.5

Expanding the left side: distributed = h + 10,000 tan 17.0 tan 12.5

Simplifying and isolating h: h = 10,000 tan 17.0 tan 12.5/(tan 12.5 - tan 17.0) ≈ 3855 ft

Therefore, the height of the plane is about 3855 feet. To find the distance from the nearer end of the runway, we use the previous equation:d = h/tan 12.5 ≈ 13580 ft

Therefore, the distance from the nearer end of the runway is about 13580 feet.

The rectangular bird sanctuary has dimensions of  12 km by 6 km in size to reduce the amount of fencing required to enclose the other three sides.

   The given rectangular bird sanctuary has a side along a straight river. To minimize the amount of fence necessary to enclose the remaining three sides, we need to find the dimensions of the rectangle.

  Therefore, let us consider that the width of the rectangular bird sanctuary is x and the length is y.

  The area of the given bird sanctuary is given as,

                A = xy= 72 km²

   The amount of fence required for the bird sanctuary can be written as,

                 F = 2x + since we are looking to minimize the amount of fence necessary to enclose the remaining three sides, we need to differentiate the expression for a fence with respect to x and equate it to zero to obtain the value of x that will minimize the fence.

              dF/dx = 2 - 0 (since dy/dx = 0)

     Therefore, dF/dx = 2 Let us consider this to be equation (1) Differentiating the expression for a fence with respect to y and equating it to zero to obtain the value of y that will minimize the fence.

             dF/dy = 0 + 1 (since dx/dy = 0)

      Therefore, dF/dy = 1

Let us consider this to be equation (2)

      Now, we can solve equations (1) and (2) to obtain the values of x and y that will minimize the fence.

            dF/dx = 2 ⇒ 2x + y

                       = 0dF/dy

                       = 1 ⇒ 2y + x

                      = 0

       Solving the above two equations for x and y, we get x = 12 km and y = 6 km

The area of the parallelogram is approximately 193.73 square meters.

How to find the area?

To find the area of a parallelogram, we need to multiply the length of one side of the parallelogram by the perpendicular distance between that side and the opposite side.

In this case, we know that one side of the parallelogram is 11.8 m and the other side is 18.5 m. Let's call these sides "a" and "b" respectively.

To find the perpendicular distance between these two sides, we need to draw a perpendicular line from one of the endpoints of side "a" to side "b". Let's call this perpendicular distance "h".

We can use the formula for the area of a parallelogram:

Area = base x height

where the base is side "a" and the height is "h".

To find "h", we can use the Pythagorean theorem:

h² = b² - (a/2)²

where "a/2" is half of side "a".

Plugging in the values we know, we get:

h² = 18.5² - (11.8/2)²

h² = 302.25 - 34.81

h² = 267.44

h ≈ 16.36

Now that we know the height of the parallelogram, we can calculate its area:

Area = 11.8 x 16.36

Area ≈ 193.73 m²

Therefore, the area of the parallelogram is approximately 193.73 square meters.

Anna's monthly Salary in June was $3600 as she received a 20% rate and her monthly Salary in July was $2880 as she received a 20% pay cut from June.

It is given to us that: Ana's salary in May =3000$

in June she received 20% raise

the amount she received in June after 20% raise = 3000 x 20/100

= 30 x 20 = 600

we have to first find Ana's salary at the end of June month with 20% raise. and then her salary after the end of July month with the pay cut of 20%.

Ana's salary after June month when she got 20% raise in his salary after May:

= 3000 + (20% x 3000)

= 3000 + (20/100 x 3000)

= $3600

her new salary after June will be 3600$.

therefore, she received 3600 in June.

in July she received 20% pay cut.

To find Ana's monthly salary after the two changes in June and July.

Ana's salary after June month when she got 20% raise in his salary after May = $3600

now she got a pay cut of 20% on his new salary from July month,

= 3600 - (20% x 3600)

= 3600 + (20/100 x 3600)

= 3600 - 720

= $2880

so, her salary after that would be equal to $2880.

The probability that each of you orders a different type of sandwich is 72%.

To find the probability that each of you orders a different type of sandwich, we can use the counting principle.
Step 1: Determine the total number of ways you and your friends can order sandwiches.

Since there are 10 types and each of you can choose any type, there are 10 * 10 * 10 = 1000 possible ways to order.
Step 2: Calculate the number of ways you can order different types of sandwiches.

For the first person, there are 10 choices.

For the second person, there are 9 remaining choices (since their sandwich must be different from the first person's). For the third person, there are 8 remaining choices (different from both the first and second person's choices). So there are 10 * 9 * 8 = 720 ways to order different types of sandwiches.
Step 3: Calculate the probability of ordering different types of sandwiches.

Divide the number of ways to order different sandwiches by the total number of ways to order:
Probability = (Number of ways to order different sandwiches) / (Total number of ways to order)
Probability = 720 / 1000 = 0.72 or 72%.

The expression 1/(1/x+2) + (1/x+3) is equivalent to (x² + 4x + 44)/x(x + 11) when x > 3.

We have,

To simplify the expression 1/(1/x+2) + (1/x+3), we can apply the concept of finding a common denominator and combining fractions.

Let's start by finding the common denominator for the two fractions.

The denominators are (1/x + 2) and (1/x + 3).

To find the common denominator, we multiply the denominators together:

Common denominator = (1/x + 2) x (1/x + 3)

Expanding the expression:

Common denominator = (1/x * 1/x) + (1/x * 3) + (2 * 1/x) + (2 * 3)

Simplifying further:

Common denominator = 1/x^2 + 3/x + 2/x + 6

Combining the fractions with the common denominator:

1/(1/x+2) + (1/x+3) = (1/x) / (1/x^2 + 3/x + 2/x + 6) + (1/x+3)

To simplify the expression further, we can multiply the first fraction by x/x to clear the fraction in the numerator:

(1/x) / (1/x² + 3/x + 2/x + 6) + (1/x+3) = (x/x) * (1/x) / (1/x² + 3/x + 2/x + 6) + (1/x+3)

Simplifying:

= 1 / (x/x * 1/x) / (1/x² + 3/x + 2/x + 6) + (1/x+3)

= 1 / (1/x²) / (1/x² + 3/x + 2/x + 6) + (1/x+3)

= 1 / (1/x²) / (1/x² + (3 + 2)/x + 6) + (1/x+3)

= 1 / (1/x²) / (1/x² + 5/x + 6) + (1/x+3)

= 1 / (1/x²) / (1/x² + 5/x + 6) + (x/x) * (1/x+3)

Simplifying further:

= 1 / 1 / (1 + 5/x + 6x/x²) + (x/x² + 3x/x)

= 1 / (1 + 5/x + 6x/x²) + (x + 3x)/x²

= 1 / (1 + 5/x + 6/x) + (4x)/x²

= 1 / (1 + (5 + 6)/x) + (4x)/x²

= 1 / (1 + 11/x) + (4x)/x²

= 1 / (x + 11)/x + (4x)/x²

= x / (x + 11) + (4x)/x²

= (x² + 4(x + 11))/x(x + 11)

= (x² + 4x + 44)/x(x + 11)

The expression 1/(1/x+2) + (1/x+3) is equivalent to (x² + 4x + 44)/x(x + 11) when x > 3.

Because you're increasing the number, you'll add the percentage to 100%. After that, use ratio to solve.

Therefore,

100% : 64

100% + 50%(150%) : ?

= 150/100 × 64

= 15/10 × 64

= 3/2 × 64

= 3/1 × 32

= 3 × 32

= 96

Answer: The nth term of the sequence is given by the formula 2n + 11

Step-by-step explanation:

The given sequence is an arithmetic sequence because the difference between each pair of consecutive terms is the same. In this case, the common difference is 2, because:

15 - 13 = 2

17 - 15 = 2

and so on

The formula for the nth term of an arithmetic sequence is:

an = a1 + (n-1)d

where an is the nth term, a1 is the first term, n is the term number, and d is the common difference.

For this sequence, the first term (a1) is 13 and the common difference (d) is 2. Therefore, the formula for the nth term is:

an = 13 + (n-1)2

Simplifying this expression, we get:

an = 2n + 11
