Amelia has a triangular kite with an area of 30 square inches and a height of 6 inches. How long is the base of the kite?

Answers

Area of triangle = 0.5 * base * height 
30 = 0.5 * 6 * base 
30 = 3 * base 
so , base = 10 inch 

Answer:

Draw a vertical line to break the kite into two equal triangles with a base of 36 and a height of 15. Use the formula A = 1

One of the corners of a cube is sliced off. The resulting cross section will have a minimum of how many sides?

Answers

3, because you cut a corner, you cut through where 3 sides meet.

3 sides

Answer:

The resulting cross-section will have a minimum of three sides.

i.e. a triangle will be formed.

Step-by-step explanation:

Because on cutting a cube along the corner we will obtain a triangle and thus a triangle has three sides.

Hence, the resulting cross section will have minimum of three sides.

( Also we can obtain many other figures on slicing a cube in different ways.

If we slice a cube parallel to the base we will obtain a square.

when we  will slice the cube to it's diagonal we will obtain a rectangle.

and in many other ways)

A cupcake shop sells an average of 14 dozen cupcakes a day to about 50 customers. What is their average sales rate, in cupcakes per customer.?

Answers

14x12=168
168/50= 3.36

Final answer:

To find the average sales rate of cupcakes per customer, you divide the total number of cupcakes sold (168) by the total number of customers (50). The result is approximately 3.36 cupcakes per customer.

Explanation:

To answer this question, you need to understand the concept of a rate, which is a ratio that compares two different kinds of units. Here, the units are the number of cupcakes sold and the number of customers.

Firstly, note that a 'dozen' equals 12. So the shop sells 14 dozen, or 168 cupcakes every day.

To compute the rate, you divide the total number of cupcakes by the number of customers: 168 cupcakes รท 50 customers = 3.36 cupcakes per customer. So, on average, each customer at the shop buys approximately 3.36 cupcakes.
