2,000 - 61k = 48
In 1962, the population of a bird species was 2,000.
The population k years after 1962 was 48, and k
satisfies the equation above. Which of the following
is the best interpretation of the number 61 in this
context?

Answers

Answer:

61 is the rate at which the population changes every year

Step-by-step explanation:

Given

[tex]2000 - 61k = 48[/tex]

Required

Interpret 61

A linear equation has the form:

[tex]y = mk + b[/tex]

or

[tex]b + mk = y[/tex]

Where m is the rate

By comparison:

[tex]mk = -61k[/tex]

[tex]m = -61[/tex]

Hence, 61 represents the rate at which the population changes yearly.

The negative sign implies that the populatiin reduces

X-3=9

41
-x = 12
X = 48
What was Mai's error?

Answers

Answer: Please see explanation column for answer.

x= -36

Step-by-step explanation:

Step 1

from the attachment, Mai's solving is given as

1/3 (1/2x- 9) = 1/2 (x+18)

1/6x-3= 1/2x+9

1/4x-3=9

1/4x=12

x=48

Mai's error started when he subtracted wrongly 1/2 x from 1/6x which gave him 1/4 x instead of - 1/3 x.

Solving correctly, we have that

1/3(1/2x-9) = 1/2(x+18)

1/6x -3= 1/2x+ 9

taking like terms to like terms

1/6x-1/2x= 9+3

(1-3)/6x= 12

-2/6x= 12

-1/3x= 12

multiplying both sides by -3

-1/3x X -3 = 12 X -3

x= -36

Jasmine has 50 marbles in a bag. 20% of the marbles are blue. How many marbles are not blue? Explain how you found your answer.

Answers

Answer:

20% of 50 marbles is 1 fifth of the marbles in the bag. so 50 marbles divided by 5 =10 blue marbles

Step-by-step explanation:

Answer:

40

Step-by-step explanation:

WOW, that's a lot of points!!

To find the answer for this problem, you take 80% of 50.

In the bag, 20% of the marbles are blue. That means that the rest of the 80% are not blue. So, take 0.8 * 50 = 40. 40 marbles that are not blue.

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4(x−6)+12=20

(4)(x)+(4)(−6)+12=20(Distribute)

4x+−24+12=20

(4x)+(−24+12)=20(Combine Like Terms)

4x+−12=20

4x−12=20

Step 2: Add 12 to both sides.

4x−12+12=20+12

4x=32

Step 3: Divide both sides by 4.

The store plans to purchase the uniforms and hand out 5 uniforms to every employee, one for each day of the week uniforms come in packs of 8, and the store plans to purchase 56 packs of uniforms. How many employees can store give uniforms to? Will the store have any uniforms left over?

Answers

Answer:

89 employees

3 uniforms left

Step-by-step explanation:

Number of Uniforms per employee = 5

Uniform per pack = 8

Number of packs = 56

Total number of uniforms :

56 * 8 = 448 uniforms

Number of employees who can get uniform :

1 employee = 5 uniforms

Number of employees = 448 / 5 = 89.6

Hence, 89 employees

Yes, (448 - (89*5)

= 448 - 445

= 3 uniforms left

Answer:

  Perimeter: 17 inches

  Area: 8 square inches

Step-by-step explanation:

The ratio of perimeters is the same as the similarity ratio.

  JKLM perimeter / ABCD perimeter = P/68 = 1/4

Multiplying by 68, we get ...

  P = 68/4 = 17 . . . . inches

__

The ratio of areas is the square of the similarity ratio.

  JKLM area / ABCD area = A/128 = (1/4)^2

Multiplying by 128, we get ...

  A = 128/16 = 8 . . . . square inches

__

Perimeter = 17 inches

Area = 8 square inches

How to calculate 46% of 50

Answers

Answer:

the answer is 23

Step-by-step explanation:

100/50=2

46/2=23

Answer:

23

Step-by-step explanation:

50/x=100/46

(50/x)*x=(100/46)*x       - we multiply both sides of the equation by x

50=2.17391304348*x       - we divide both sides of the equation by (2.17391304348) to get x

50/2.17391304348=x

23=x

x=23

now we have:

46% of 50=23
