Answer:

113

Step-by-step explanation:

note: to find the circumference of a circle using the radius, you use this equation -- 2 $\pi$ r. since the radius is 18, you make the equation 2 $\pi$ 18. that gets you 36 $\pi$ , which, if put into the calculator, is about 113.

Sally has $200 in her savings account last month. She added $35 this month and earned $0.75 interest. What is the percent of the

Phoenix [80]

Answer:

The percentage increase in the amount in her savings is 17.9%

Step-by-step explanation:

The formula for percentage increase is given as,

$Percentage\:Increase=\dfrac{New\:Value-Old\:Value}{Old\:Value}$

In previous month, amount of saving in Sally’s account was $200.

In the current month she added $35 and earned an interest of $0.75. So the total earning in current month will be,

Total earning = Amount in previous month + Amount added + Interest earned

Total earning = $ 200 + $ 35 + $ 0.75

Total earning = $235.75

So, current month amount of saving in account is $ 235.75 which becomes new value and previous month balance that is $ 200 becomes old amount.

Therefore, New value = $ 235.75 and Old value = $ 200

Substituting the values in the formula,

$Percentage\:Increase=\dfrac{235.75-200}{200}$

$Percentage\:Increase=\dfrac{35.75}{200}$

$Percentage\:Increase=0.17875$

$Percentage\:Increase=17.875$

Rounding to nearest tenth means one digit after the decimal place. So, percentage increase is 17.9 %

Answer:

Interrater reliability between the two data collectors was high

Step-by-step explanation:

Explanation-

Interrater reliability is the consistency of observations between two or more observers.

An Agreement of 54 out of 56 scores would indicate a high level of interrater reliability.

The data collection method was appropriate for pressure ulcer risk assessment.

The risk assessments did not have to be done by both evaluators at the same time.

sorry I don't know Ab = cd and bc = ad

Using SAS postulate triangles formed by ABC = abd

Opposite sides are equal and each angle is 90 degrees so by definition it is a rectangle.Ab = cd and bc = ad

What is the surface area of this figure?

disa [49]

Answer:

72 sq. mi

Step-by-step explanation:

Breaking this down, we have 2 right triangles with sides of 3, 4, and 5 miles, and 3 rectangles with dimensions 3 x 5, 4 x 5, and 5 x 5 miles. Remember that the area of a triangle is 1/2 x b x h , where b and h are the triangle's base and height. The base and height of the triangles at the bases of the figure are 3 and 4, so each triangle has an area of 1/2 x 3 x 4 = 1/2 x 12 = 6 sq. mi, or 6 + 6 = 12 sq. mi together.

Onto the rectangles, we can find their area by multiplying their length by their width. Since the width of these rectangles is the same for all three - 5 mi - we can make our lives a little easier and just "glue" the lengths together, giving us a longer rectangle with a length of 3 + 4 + 5 = 12 mi. Multiplying the two, we find the area of the rectangles to be 5 x 12 = 60 sq. mi.

Adding this area to the triangle's area gives us a total area of 12 + 60 = 72 sq. mi.
