Answers

The correct answer is A.10.
The answer for this is A. 10
In this type of question, you need to transfrom the amount of percentage into fractions first and multiply it as usual.

40%  =   40/100    = 4/10 

So, 40% of 25 is:

Rohan did a survey in four bird parks and wrote the following observations:


Bird Park Survey
Park Number of Yellow Birds Total Number of Birds
P 33 53
Q 20 48
R 54 90
S 44 83


Based on the survey, which park had the greatest percentage of yellow birds?
Park P
Park Q
Park R
Park S

Answers

Answer:  Park P

Step-by-step explanation:

Since, According to the question,

Number of yellow bird in park P = 33

Total number of the bird in park P = 53

Thus, the percentage of yellow bird in park P = [tex]\frac{33}{53} \times 100[/tex]= 62.264150943% ≈ 62 %

Number of yellow bird in park Q = 20

Total number of the bird in park Q = 48

Thus, the percentage of yellow bird in park P = [tex]\frac{20}{48} \times 100[/tex]=41.666666666% ≈ 42%

Number of yellow bird in park R = 54

Total number of the bird in park R = 90

Thus, the percentage of yellow bird in park R = [tex]\frac{54}{90} \times 100[/tex]= 60 %

Number of yellow bird in park S = 44

Total number of the bird in park S = 83

Thus, the percentage of yellow bird in park P = [tex]\frac{44}{83} \times 100[/tex]=53.012048192 % ≈ 53 %

Since, 62% > 60% > 53% > 42%

Therefore, highest percentage of the yellow bird is 62 %

Which is present in park P.

What x Value makes this equation true ?

Answers

So what you want to do is move all the variables to one side and numbers to the other.

x-3 = 3x + 7

So first move all the variables to one side:

x - 3x - 3 = 7

Then the numbers.

x- 3x = 7 + 3

​3/8 c−2= ​3/2 c−12 helpp

Answers

Final answer:

The solution involves clearing the equation of fractions, rearranging terms to isolate the variable c, and then solving for c by dividing both sides by 9 to obtain c = 80/9.

Explanation:

The student is asking for help solving a linear equation. To assist with this mathematics problem, it's crucial to use algebraic methods to isolate the variable c. Here is the step-by-step solution:

Given:

​3/8 c − 2 = ​3/2 c − 12

First, let's clear the fractions by multiplying every term by 8 to get rid of the denominators:

8(​3/8 c) − 8(2) = 8(​3/2 c) − 8(12)

Which simplifies to:

3c − 16 = 12c − 96

Next, subtract 3c from both sides to move all terms with c to one side:

− 16 = 9c − 96

Now, add 96 to both sides to isolate the c term:

80 = 9c

Finally, divide both sides by 9 to get the value of c:

c = 80 / 9

The table shows Katrina's prices for dog walking. If she walks 5 medium-sized dogs and 8 large-sized dogs for 12 weeks, how much will she earn?

Table:
•Small Dog = $10 Per Week
•Medium Dog = $12 Per Week
•Large Dog = $14 Per Week

Answers

5x$12= 60$ so 60$per week 60$x12 = $720 for the Medium dogs.

8x14$= 112$ per week, she walked them 12 weeks. 112x12= $1344 for the large dogs.

Now take the two prices $720+$1344= $2,064 

She earned a total of $2,064 from walking the dogs.

A weed called the boomstar vine is known for growing at a very fast rate. It can grow up to 0.5 feet per day. How fast in inches per day can the boomstar vine grow up to? How fast in inches per hour can the boomstar grow up to?

Answers

It can grow 6in per day, and 0.25 inches per hour.
Final answer:

The Boomstar vine can grow up to 6 inches per day and 0.25 inches per hour, after converting from feet to inches and dividing by the number of hours in a day, respectively.

Explanation:

The Boomstar vine can grow up to 0.5 feet per day. To convert feet to inches, we multiply by the conversion factor of 12 inches per foot. Therefore, multiplying 0.5 feet by 12 gives us:

0.5 feet/day × 12 inches/foot = 6 inches per day.

Next, to find out how fast it grows in inches per hour, we divide the daily growth in inches by the number of hours in a day:

6 inches/day ÷ 24 hours/day = 0.25 inches per hour.

Solve each compound inequality and graph the solution.

1. 2x + 5 > −3 and 4x + 7 < 15

2. 2x − 5 > 3 or −4x + 7 < −25

Answers

1) x > -4 and x < 2

2) x > 4 and x <8

The required solution for inequality 1 is x >-4 and x < 2, and for inequality 2 is     x > 4  or  x > 8.

What is inequality?

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

Here,
1. 2x + 5 > −3 and 4x + 7 < 15
  2x > -8  and 4x < 8
  x > -4   and x < 2

2. 2x − 5 > 3 or −4x + 7 < −25
   2x > 8  or -4x < -32
     x > 4  or  x > 8

Now, plotting graph for both inequalities,
the double-shaded portion on the graph is the required solution for inequalities in section 1 of the question, and solution for the section 2 of the question is each shaded area of the graph.

Thus, the required solution for inequality 1 is x >-4 and x < 2, and for inequality 2 is     x > 4  or  x > 8.

Hello there.

6(8 - 2y) = 4y

To solve for this, we need to apply the Distributive Property to the left side of the equation. This property allows us to multiply the number outside of the parenthesis by all numbers inside of the parenthesis.

6(8 - 2y)
6(8) + 6(-2y)
48 - 12y

Now, let’s take a look at our equation.

-12y + 48 = 4y

To make things more simple, we’ll add 12y to both sides of the equation. This will cancel out -12y on the left side of the equation and will turn 4y on the right side of the equation into 16y.

Our new equation is:

16y = 48

Now all we need to do is divide both sides by 16 to solve for y.

16y / 16 = y
48 / 16 = 3

Our final answer and solution is:

Y = 3
