Alexandra purchases two doughnuts and three cookies at a doughnut shop and is charged $3.30. Brianna purchases five doughnuts and two cookies at the same shop for $4.95. All the doughnuts and cookies have the same price. Find the cost of one doughnut and the cost of one cookie.

Answers

Answer 1
Answer:

The cost of one doughnut is $0.75 and the cost of one cookie is $0.60.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Alexandra buys two doughnuts and three treats at a donut shop and is charged $3.30. Brianna buys five doughnuts and two treats at a similar shop for $4.95. Every one of the doughnuts and treats has a similar cost.

Assume 'x' is the cost of doughnuts and 'y' is the cost of one cookie. Then the equations are given as,

2x + 3y = 3.30         ...1

5x + 2y = 4.95        ...2

Multiply equation 1 by 5 and equation 2 by 2, then we have

10x + 15y = 16.50     ...3

10x + 4y = 9.90       ...4

Subtraction equation 2 from equation 1, then we have

15y - 4y = 16.50 - 9.90

11y = 6.60

y = $0.60

Then the value of 'x' is given as,

2x + 3(0.60) = 3.30

2x + 1.80 = 3.30

2x = $1.50

x = $0.75

The expense of one donut is $0.75 and the expense of one treat is $0.60.

Answer 2
Answer: Answer:1 donut=$0.75 and 1 cookie=$0.6

let c be the cookie and d be the dougnut

2d +3c = 3.30 ---eq 1
5d+ 2c = 4.95 ---eq 2

Find the area of each of the separated pieces

Answers

The best way ( meaning, the way that results squares with the biggest areas ) is to cut it in 2 squares with the lenght of 10cm. Then, the area is 10*10 cm = 100 cm^2

Why cut it like this? We find the highest number that divides both 20 and 10, in this case it's 10. Then, we can cut squares with the lenght of 10 cm. But we have a rectangle with the area of 20*10=200 cm^2 , and we cut squares of 10*10=100cm^2. 200/100=2. So we cut 2 squaresAlso, you could say that it's because the simmetry line cuts the rectangle in 2 other simetrical rectangles, which in this case, happen to be squares.

Rashida bought 3 tickets to a concert for $75.A this rate how much would 5 tickets cost

Answers

Answer: The cost of 5 tickets =  $125

Step-by-step explanation:

We are given that , the cost of 3 tickets = $ 75

Then , By Unitary ,method

The cost of one ticket= (cost of 3 tickets) ÷ (3)

= ($75) ÷ (3)

= $25

Now , if the rate is same , the cost of 5 such tickets will be

5 x (Cost of one ticket)

= 5 x ($25)

= $125

Hence , the cost of 5 tickets =  $125

First divide 75 by 3 to figure out what the cost of 1 ticket is.
75÷3 = 25
so, 1 ticket costs $25
now multiply 25 by 5
25*5= 125
so 5 tickets would cost $125

On a given morning the temperature was 71°F. The temperature dropped 5°F and then rose 8°F. How much does the temperature need to rise or fall to return to the initial temperature of 71°F? A) Fall 8°F
B) Fall 3°F
C) Rise 8°F
D) Rise 5°F

Answers

The temp starts at 71 degrees then drops 5 degrees

71 - 5 = 66 degrees

then it rises 8 degrees

66 + 8 = 74 degrees

How much does the temp have to rise or fall to get back to 71...

74 - 71 = 3 degrees

It has to fall 3 degrees F.  Answer B.


B.  Fall 3°F is your answer.


Which of the following is true for two complementary angles ∠RST and ∠TSU?Question 4 options:

A)

m∠RST + m∠TSU = 90°

B)

m∠RST + m∠TSU = 180°

C)

m∠RST = m∠TSU

D)

m∠RST = ½ × m∠TSU

Answers

Answer:

Option "A" is the correct answer to the following question.

Step-by-step explanation:

Complementary angles ⇒ If the sum of two angles becomes 90 degrees, we can say that this is a complementary pair of angles.

In the given situation angle ∠RST and ∠TSU are a pair of complementary angles.

∠RST + ∠TSU = 90° (Complementary angles)

So, we say that the option "A" is the correct answer.

Answer:

Option A

Danny`s jump rope is 6 meters long how many centimeters is his jump rope? and how?

Answers

Here's how I was taught to do this:

(6meters)/(1)| (100centimeters)/(1meter)   \n  (6*100centimeters)/(1)  \n 600 centimeters

The answer is 600 cm.

Hope this helps!!
600 because there are 100 centimeters in 1 meter so if you add 100 6 times then your answer will be 600.
