Step-by-step explanation:

find the measure

M of r = 75°
Xy = 6
M of x = 55°
M of s = 50°
Because the triangles are congruent the corresponding angles are also going to have congruent measures but I’m not sure if 6 is the right answer for the measure of XY because I took geo last year so it might not be right

The square of 356 is 126,736 and the square of 357 is 127,449. What is 3582? Try to solve this problem without multiplying. Show your work.

Answers

Answer:

The problem to get 358² is solved by adding 357 twice and then add 1 to the value of 357²

Step-by-step explanation:

The given information are;

The square of 356 = 126,736

The square of 357 = 127,449

We note that 357² = (356 + 1)² = 356² + 2×356 + 1 = 126,763 + 712 + 1 = 127,449

We can write the above equation as follows;

357² = (356 + 1)² = 356² + 356 + 356 + 1 = 126,763 + 712 + 1 = 127,449

357² = 127,449

Similarly, we have;

358² = (357 + 1)² = 357² + 357 + 357 + 1 = 128,164

358² =  128,164

We can also look at the question as forming squares with tiles

To form the square tile with 358 units per side, we add an extra row and column of 357 tiles each. Completing the figure with an extra tile at the top right or left corner

Therefore, the area of the 358 unit per side square = The area of the 357 unit per side + 357 + 357 + 1 =  128,164

Last week, a GameStop store sold some $43 games and some $30 games for a total of
$485. What was the total number of games sold?
Explain your reasoning.

Answers

Answer: The total number of games sold by the GameStop is 14. That is 5 games of $43 and 9 games of $30.

Step-by-step explanation:

Considering some games of $43 were sold and others for $30 were also sold in arriving at the total of $485 sold.

If 5 games of $43 were sold it gives $215.

To get the difference, you subtract the amount sold for $43 from the total.

$485 - $215 = $270

To arrive at how many $30 games were sold;

$270 ÷ $30 per game = 9 games

Therefore, 5 games of $43 combined with 9 games of $30 gives a total of 14 games.

Shanice's Bakery makes two types of wedding cakes: Pink cake, which sells for $30, and Yellow cake,
which sells for $35. Both cakes are the same size, but the decorating and assembly time required for the
Pink cake is 2 hours, while the time is 3 hours for the Yellow cake. There are 420 hours of labor available
for production. How many of each type of cake should be made to maximize revenue?

Answers

Answer:

210 Pink cakes and 0 Yellow cakes

Step-by-step explanation:

Since the Yellow cake takes about %33.3 more time to prepare but only about %16.6 more revenue, it's always more profitable to make Pink cakes.

Answer:

#1) 25  degrees   #2) 155 degrees    #3) 25  degrees    #4) 25  degrees   #5) 5x+15= 110

Step-by-step explanation:

basically the use the vertical angle relationship to figure it out

that would mean that 4=155 and 3=1 and since the relationship is straight angle pair it means that 155+ x= 180    180-155= 25  

5) CDE= FDG this is the vertical angle rule so 5x+15= 8x-42      

solve that by adding like terms, 5x-15= 8x-42 +15      by doing adding to both sides it eliminates the 15 because you added it with the like terms, -42 and got -57

-57+8x= 5x   now subtract 8 on both sides, -57= -3x    divide and it equals 19

now plug that back into the eqaution of 5x+15   5(19)= 95 + 15= 110

4. Two times a number added to another number is 25. Three times the first number minus the other number is 20. Find the two numbers.

Answers

Answer:9 & 7

Step-by-step explanation:

Let x be the first number and y be the second.

 

2x + y = 25

3x - y =20

 

1) Add them together.

 

5x = 45

x = 9

 

2) Solve for y.

 

2(9) + y = 25

y=7

 

3) Check your work on the other equation.

 

3(9) - (7) = 20

27 - 7 =20

20 = 20

I think it’s 3,996.35 if you use PEMDAS and you multiply 74 by 54 to get 3,996 then you divide 7 over 20 to get .35 and you then add them together to get 3996.35
74 x 54 = 3,996

7\ 20 = 0.35

3,996 + 0.35 = 3,996.35

Answers

Answer:

2.26 hours

Step-by-step explanation:

Given that:

Stock 1:

Initial price = 13.17

Rate of increase = $0.11 per hour

13.17 + 0.11h - - - (1)

Stock 2 :

Initial price = 13.69

Rate of decrease = 0.12 per hour

13.69 - 0.12h - - (2)

13.17 + 0.11h = 13.69 - 0.12h

0.11h + 0.12h = 13.69 - 13.17

0.23h = 0.52

h = 0.52 / 0.13

h = 2.26 hours

taking x common and 2 common we get ,
