'2aa4b' is a 5 digit number and when its divided by '36' it gives '11' as remainder. What is the sum of the values 'a' can have.

Answers


The only 5-digit numbers that do the job are  21,143  and  28,847 .

So, either 
a = 1  and
b = 3

or
a = 8  and
b = 7 .

The sum of the values that 'a' can have is (1 + 7) = 8 .

An airplane over the Pacific Ocean sights an atoll at an 7° angle of depression. If the plane is 663 m above the water, how many kilometers is it from a point 663 m directly above the atoll?(Hint: Make sure your calculator is in degrees!)A. 5399.7 km
B. 5.4 km
C. 81.41 km
D. 760.8 km

Answers

You need to draw the diagram to understand the problem easily. Teh diagram will show the right triangle, acute angle with the base  7º, height is 663 m, and "x" is the base of the triangle. 

using the tangent ratio: 

tan
Θ = opposite / adjacent

tan7º = 663 m / x 

x = 663 m / tan7º
x = 5,399.7 m 

change m to km. 1,000 m = 1km

5,399.7m * 1km/1,000 m = 5,399.7 km/1000 = 5.3997 km or 5.4 km

B. 5.4 km

Kate is selling bracelets and earrings on Etsy to make money for summer vacation. The
bracelets (x) cost $2 and earrings (y) cost $3. She needs to make at least $100, but can
only make up to 40 pieces of jewelry. Which inequalities represent this situation?
2x + 3y > 100
x + y = 40
100x + 2y = 3
x + y = 40
100x + 40y > 100
3x + 2y = 40
3x + 2y > 100
x + y = 40

Answers

Answer:

2x + 3y > 100

x + y = 40

Step-by-step explanation:

This is the answer because it shows the price of each and the combined products equaling more than 100 dollars, and the bottom one shows that the combined total of jewelry can not exceed 40 pieces.

Final answer:

The inequalities that represent Kate's situation are 2x + 3y > 100 and x + y ≤ 40.

Explanation:

In this situation, we can use the inequalities 2x + 3y > 100 and x + y ≤ 40 to represent Kate's goal of making at least $100 and making up to 40 pieces of jewelry. The inequality 2x + 3y > 100 ensures that the total cost of the bracelets and earrings is greater than $100, and the inequality x + y ≤ 40 guarantees that the total number of jewelry pieces is not more than 40.

1. Discuss the differences between the measurement of the surface area and the measurement of the volume of a right rectangular prism. Include the following topics in your discussion:• Description of regions that are measured
• Units for each type of measure and why the units are different
• Examples of when you would want to measure for each type of measure.

Answers

Surface area define or calculate the exact space that each face of the said shape is taken up while the volume is how much space is inside the said object. The area use the unit that is squared because it only measured 2 face in the shape while the volume measures 3 faces in the object. an example of an area is a card board area, while the volume is the glass of water.

at a lunch stand, each hamburger has 50 more calories than each order of fries. if 2 hamburgers and 3 orders of fries have a total of 1700 calories, how many calories does a hamburger have?

Answers

The correct answer is 370. A system of equations can be used, where h represents the number of calories in a hamburger and f represents the number of calories in an order of fries. The equation  2 h plus 3 f equals 1,700 represents the fact that 2 hamburgers and 3 orders of fries contain a total of 1700 calories, and the equation  h equals f plus 50 represents the fact that one hamburger contains 50 more calories than an order of fries. Substituting  f plus 50 for h in  2 h plus 3 f equals 1,700 gives  2, parenthesis, f plus 50, close parenthesis, plus 3 f, equals 1,700. This equation can be solved as follows:

 

 2 f plus 100 plus 3 f equals 1,700

 5 f plus 100 equals 1,700

 5 f equals 1,600

 f equals 320



The number of calories in an order of fries is 320, so the number of calories in a hamburger is 50 more than 320, or 370.
