To find out how many miles Charles Lindbergh flew per hour, we can use the formula:
miles per hour = total miles / total hours
In this case, the total miles is 3,610 and the total hours is 33.5. Plugging in these values, we get:
miles per hour = 3,610 / 33.5
miles per hour = 107.7 (approximately)
So Charles Lindbergh flew about 107.7 miles per hour during his first solo flight across the Atlantic Ocean.

The shape of the parallelogram with vertices P(−4,0), Q(0,4), R(4,0), and S(0,−4) is a square
How to solve for the shapeIn order to get the shape using the vertices that we have, we would have to find the length of the diagonals
We have P(−4,0), Q(0,4), R(4,0), and S(0,−4)
The length of the diagonal PQ is given as:
PQ = [tex]\sqrt{(0-4)^2+(4-0)^2}[/tex]
= [tex]\sqrt{32}[/tex]
Next we have to solve for the length of the diagonal RS
RS = [tex]\sqrt{(4-(-4))^2+(0-(-4))^2[/tex]
RS = [tex]\sqrt{32}[/tex]
Since PQ = RS we would have to conclude that the shape is a square.

If 3/4 cup of chai tea latte concentrate is 60 calories, how many calories is 1/2 cup of chai tea latte concentrate?
If 3/4 cup of chai tea latte concentrate is 60 calories, we can use proportion to find out how many calories 1/2 cup of chai tea latte concentrate is.
What does a math ratio mean?
An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. For instance, you could athe ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls) There are 1 in 4 boys and 3 in 4 girls.
We know that:
(3/4 cup) = 60 calories
To find out the number of calories in 1/2 cup, we can set up a proportion using the information we have:
(1/2 cup) / x = (3/4 cup) / 60
we can cross-multiply to get:
x = (1/2 cup) * (60 / (3/4 cup))
then we can simplify
x= (1/2)*(4/3)*60
x= 80/3
Therefore, 1/2 cup of chai tea latte concentrate is 80/3 calories.

The equations that represent the circle are x² + (y - 3)² = 36 and x² + (y + 8)² = 36.
What is Circle?A circle is a two dimensional figure which consist of all the points which are at equal distance from a fixed point called center of the circle.
Standard equation of a circle is,
(x - h)² + (y - k)² = r², where (h, k) is the center and r is the radius.
Given that,
Diameter = 12
Radius = Half of diameter = 6
Center lies on the y axis.
So the coordinates of center (h, k) will be of the form (0, k).
So the equation will be of the form,
(x - 0)² + (y - k)² = 6² or x² + (y - k)² = 36
The equations of this form in options are,
x² + (y - 3)² = 36 and

In Geometry, triangles are the type of polygons, which have three sides and three vertices. This is a two-dimensional figure with three straight sides. A triangle is considered a 3-sided polygon. The sum of all the three angles of a triangle is equal to 180°. The triangle is contained in a single plane. Based on its sides and angle measurement, the triangle has six types.
Based on the sides of a triangle, a triangle is classified into 3 types, namely:
Scalene Triangle – All the sides are of different measures.
Isosceles Triangle – Two sides of a triangle are of the same measure and the remaining side has a different measure.
Equilateral Triangle – All the 3 sides of a triangle are of the same measure.
Based on the angles of a triangle, a triangle is classified into 3 types, namely:
Acute Angle Triangle – All the angles of a triangle is less than 90°.
Obtuse Angle Triangle – One of the angles of a triangle is greater than 90°.
Right Angle Triangle – One of the angles of a triangle is equal to 90°.

investment to double its value at an interest rate of 3.60%, compounded
annually?
Approximately 20 years will it take a $1000.00 investment to double its value at an interest rate of 3.60%, compounded annually.
What is rule of 72?The rules of 72, 70, and 69.3 are ways for calculating the doubling time of an investment in finance. To determine the roughly necessary number of periods for doubling, the rule number is divided by the interest percentage each period. For modest rates of return, the Rule of 72 is fairly accurate. The Rule of 72's estimates are compared to the actual number of years it takes for an investment to double in the graph below. Although it provides an estimate, the Rule of 72 becomes less accurate as rates of return rise.An investor or advisor can easily determine using the Rule of 72 how long it will take an investment to double based on its fixed annual rate of return. You may determine roughly how long it will take for your portfolio to double in size by dividing 72 by the fixed rate of return.Approximately 20 years will it take a $1000.00 investment to double its value at an interest rate of 3.60%, compounded annually.

here, C(x) = 30x + 5. replace x with 0.7 to get
C(0.7) = 30*0.7 + 5= 26
2. C(x) = 30x + 5 = 50
30x+5 = 50
subtract 5 from both sides to isolate x and its coefficient
30x = 45
