In a two digit number, the sum of the digit is 14. Twice the tens digit exceeds the units digit by one. Find the numbers?​

Answers

Answer 1

Answer:

59

Step-by-step explanation:

x= tens place of number

y= ones place of number

set up equations:

"sum of the digit is 14"

sum is the result of addition

x+y=14

"Twice the tens digit exceeds the units digit by one"

2x is bigger than y by 1

if 2x is bigger, then add 1 to the opposite side to balance the equation:

2x=y+1

with 2 equations you can solve for 2 variables:

2x=y+1

2x-1=y

substitute into x+y=14

x+(2x-1)=14

3x-1=14

3x=15

x=5

------

subtitute to find y

x+y=14

5+y=14

y=9

number is 59

the sum of the interior angle in a polygon is 40,500° what is the number of sides in the regular polygon

Answers

Answer:

227 sides

Step-by-step explanation:

The sum of the interior angles of a convex polygon is S=180(n-2) where n is the number of sides. If S=40500, then we have our equation 40500=180(n-2) and we can solve for n:

40500 = 180(n-2)

225 = n-2

227 = n

Therefore, the number of sides in the regular polygon is 227.

Jason and Krystal are selling pecan pies and strawberry cheesecakes for a school fundraiserJason sold 9 pecan pies and 8 strawberry cheesecakes for a total of $153. Krystal sold 2 pecan pies and 6 strawberry cheesecakes for a total of $72. If it is possible to find them, what is the cost of each pecan pie and strawberry cheesecake ? If not possible , explain why

Answers

From the equation that was gotten, the value of the pecan pies and the cheesecake will be $9 each.

Based on the information given, the equations to solve the question will be:

9p + 8s = 153 ..... i

2p + 6s = 72 ..... ii

Multiply equation i by 2

Multiply equation ii by 9.

18p + 16s = 306

18p + 54s = 648

Subtract the equations

38s = 342

s = 9

Since 2p + 6s = 72

2p + 6(9) = 72

2p + 54 = 72

2p = 72 - 54.

2p = 18

p = 18/2 = 9

They're both $9 each

Parallelogram ABCD has vertex coordinates A(0, 1), B(1,3), (4,3), and D(3,1). It is translated 1 unit to the right and 3 units down and then rotated 180°clockwise around the origin. What are the coordinates of A?

Answers

Answer:

This is a plan view of a garden. The grass (shaded) has an area of 64 square metres. What is the length of the sides labelled x?
A. 5.5m
B. 6.0m
C. 6.8m
D. 9.0m
Please answer

Answers

The length of the sides of the square labelled x is b. 6.0 m.

Recall:

The formula for the area of a square with equal side, s, is given as s².

Given that the grass area is 64 sq. meters, to find the length of the sides labelled x, first find the area tat has sides labelled x.

Area = Total area of the garden - 64 sq. m

Area = (10 × 10) - 64

Area = 36 sq. m.

Area of square = s²

Lex x = s

Therefore:

x² = 36

Take the square root of both sides

x = 6 m

Therefore, the length of the sides of the square labelled x is b. 6.0 m.

Question 9 is based on the source below:The advent of printing ought to be featured more prominently by historians of science when they explain the downfall of outdated scientific ideas that occurred during the Scientific Revolutions after 1500. For it was printing, and the creation of mass numbers of books, that led directly to empiricism: the theory that all knowledge is derived from sense-experience and experimentation, as well as the refinement of the scientific method of observation, experimentation, and publishing of the results of those experiments. For it was printing that created that all-important text for researchers of all kinds: the secondary source.The Renaissance scholars made eliminating errors one of their major goals, since the copying work of medieval scribes often involved the perpetuation [spread] of terrible errors from original sources. This drive for error-correction inspired the scientists of the Scientific Revolution to conduct experiments to make sure that knowledge was directly observable and verifiable. These scientists would then publish the results of their experiments in order to correct the scientific record. These published experimental results formed a base of secondary sources that could be used by each next generation of scientists as they made new discoveries and advances in the fields of physics, astronomy, medicine, anatomy, mathematics and geometry, geography and cartography.Printing increased the faith that scientists could have in written sources, making archival research a trusted and required part of the scientific process. Scientists also began publishing their findings in journals and magazines limited entirely to scientific ideas, created a European society of scientists in constant written conversation with each other.Excerpt from The Printing Revolution in Early Modern Europe, Elizabeth Eisenstein, 1983.9.
