Aaron and Maria collected shells one morning at the beach. Maria had 3 times as many as Aaron, but they would have the same number of shells if Aaron had found 8 more and Maria had found 6 less. How many shells did Aaron collect?

Answers

Answer 1
Answer:

As per the concept of unitary method, Aaron collected 7 shells.

Let's assume that Aaron initially collected "A" shells, and Maria initially collected "M" shells.

According to the first piece of information, Maria had three times as many shells as Aaron: M = 3A.

Now, according to the second piece of information, if Aaron had found 8 more shells and Maria had found 6 fewer shells, their final shell counts would have been the same. So, Aaron's final count would be A + 8, and Maria's final count would be M - 6.

Given that the final counts are equal, we can set up an equation:

A + 8 = M - 6.

Now, we can substitute the value of M from the first piece of information (M = 3A) into the equation above:

A + 8 = 3A - 6.

Next, let's solve for A:

8 + 6 = 3A - A,

14 = 2A.

Finally, we can find the value of A by dividing both sides of the equation by 2:

A = 14/2,

A = 7.

So, Aaron collected 7 shells.

Answer 2
Answer: 3A = M
A + 8 = M - 6
3A = M

A + 8 = 3A - 6
A + 14 = 3A
14 = 2A
A = 7

M = 3A
M = 3 x 7
M = 21

So overall Aaron had 7 shells, and Maria had 21.

4^3 • 5^3 and 20^3, Are the expressions equivalent? Yes or no?

Answers

Hey there!

4^3 * 5^3 = ?

4^3

= 4 * 4 * 4

= 16 * 4

= [64]

5^3

= 5 * 5 * 5

= 25 * 5

= [125]

125 * 64

= [8,000]

20^3

= 20 * 20 * 20

= 400 * 20

= 8,000

8,000 = [8,000]

Therefore, this statement is TRUE so your answer is: [YES]

The amount of money left on a loan that Kira owes her grandmothers is represented by the function k(t)=280(.88)^t where k(t) represents the amount of money left on a the loan and t represents the time, in years. Find r, the percent change and explain what it represents.

Answers

Given:
k(t) = 280(0.88)^t

t = 1 ; t = 2 ; t = 3 
k(1) = 280(0.88)¹ = 280(0.88) = 246.40
k(2) = 280(0.88)² = 280(0.7744) = 216.83
k(3) = 280(0.88)³ = 280(0.681472) = 190.81

280 - 246.40 = 33.60 ⇒ 33.60/280 = 0.12
246.40 - 216.83 = 29.57 ⇒ 29.57/246.40 = 0.12
216.83 - 190.81 = 26.20 ⇒ 26.20/216.83 = 0.12

The rate is 0.12 or 12%

find the dimensions of rectangle whose perimeter is 112cm and whose breadth is 4 cm less than half its length​

Answers

Answer:

Length = 40 cm

Width = 16 cm

Step-by-step explanation:

Length = x

Width = 1/2x -4

2 times length + 2 times width = perimeter

2x + 2(1/2x - 4) = 112 cm

2x + 2/2 x - 8 = 112 cm

2x + x = 112 + 8

3x = 120

x = 120/3

x = 40

Width = 40/2 - 4

The weight of male Americans between the ages of 18 and 25 is normally distributed, with a mean of 164.5 lb and a standard deviation of 26 lb. One definition of obesity states that a person is obese if the z-score of his or her weight is greater than 2.What is the obesity threshold weight for a young adult American male? Round your answer to the nearest tenth.

Answers

Z- score equal to 2 means 2 standard deviations greater than the mean.
Mean + 2 z = 164.5 + 2 * 26 = 164.5 + 52 = 216.5
