The sum of two numbers is 68. Their difference is 15. Write a system of equations you could use to solve this problem.

Answers

Answer 1

Answer:

x+y=68

x-y=15

Step-by-step explanation:

A "sum" means that we will be using addition, while a "difference" indicates subtraction. Anytime we have two unknown numbers we generally use "x" and "y".

How many reflectional symmetries does this figure have?
Enter your answer in the box

reflectional symmetries
How many rotational symmetries does this figure have?
Enter your answer in the box
rotational symmetnes

Answers

Answer:

There are no reflectional symmetries.

Step-by-step explanation:

Hi there, a reflectional symmetry requires the reflection to mirror that of the figure being reflected. To put it in simpler terms, it should look exactly the same if you put one half right next to a mirror.

I hope this clears up things a bit.

The required, latter F does not have reflectional symmetries.

What is Reflection symmetry?

Reflection symmetry is a type of symmetry where a figure is reflected across a line, called the line of symmetry, and the resulting figure is identical to the original. In other words, if you were to fold the figure along its line of symmetry, the two halves would match up perfectly.

Since we have given the figure of latter F, which does not have reflectional symmetries.

It's important to note that not all letters have reflectional symmetry, but the letter "F" is one example of a letter that does have this type of symmetry.

kim has 8 vanilla candles, 4 cherry candles and 6 raspberry candles. what is the probability that kim will choose a cherry candle?

Answers

there’s 18 candles in total

-8 vanilla
-4 cherry
-6 raspberry

4/18 would represent the number of cherry candles. this could also be written as 22.22%, or just 22%


hope i was able to help you!

The probability that Kim will choose a cherry candle is [tex]\frac{2}{9}[/tex] OR 0.22

From the question,

We are to determine the probability that Kim will choose a cherry candle out of the possible candles

From the given information

Number of vanilla candles = 8

Number of cherry candles = 4

Number pf raspberry candles = 6

∴ Total number of candles = 8 + 4 + 6 = 18

Using the formula

[tex]Probability = \frac{Number\ of\ favorable\ outcomes}{Total\ number\ of\ outcomes}[/tex]

For the probability to choose cherry candle

Number of favorable outcome = 4

Total number number of outcomes = 18

∴ Probability of choosing cherry candle = [tex]\frac{4}{18}[/tex]

Probability of choosing cherry candle = [tex]\frac{2}{9}[/tex] OR 0.22

Hence, the probability that Kim will choose a cherry candle is [tex]\frac{2}{9}[/tex] OR 0.22

a. 8 cakes
c. 7 cakes
b. 2 cakes
d. 4 cakes

Answers

Answer:

a. 8

Step-by-step explanation: Out of  12   baked goods sold , let the number of cakes sold, be  x  in number and pies sold were  12 − x  in number. Total sell was  $ 144  ,  1  cake costs  $ 14  and  1  pie costs, $ 8 ∴ 14 ⋅ x + ( 12 − x ) ⋅ 8 = 144 or 14 x − 8 x = 144 − 96  or 6 x = 48 ∴ x = 8
