Answer:

120 bronze and silver medals were won.

Step-by-step explanation

silver = 30% of the medals

30% of 150 is 45

bronze = 50%

50% of 150 is 75

45 + 75 = 120

Considering area (A) of garden as 30 square feet:

30 = x(2x+7)

Now we need to expand it:

x(2x+7) = 2x^2 + 7x

2x^2 + 7x = 30

Adding this into an Algebra calculator gives us 5/2 or 2.5

So x = 2.5

To prove this:

2(2.5) + 7 = 12

14 * 2.5 = 30

Since the area is equal to length times width, and you know your area has to be 30, you can plug in your values like this:

(2x+7) x = 30

you can distribute to make this easier

2x^2 + 7x = 30

you can plug this into quadratic formula by setting the equation =0, so:

2x^2 +7x -30 = 0

where 2x^2 = a
7x = b
and -30 = c

you can plug this into your calculator and get an answer of

X = 2.5

the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there

Answers

Answer:

Step-by-step explanation:

To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.

Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.

The sum of the parts in the ratio is 8x + 5x + 2x = 15x.

We know that the total number of fruits is 120. Therefore, we can set up the following equation:

15x = 120

To solve for x, we divide both sides of the equation by 15:

x = 120 / 15

x = 8

Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:

Number of bananas = 2x = 2 * 8 = 16

So, there are 16 bananas in total.

We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

The constant of Proportionality is 8.

What is constant of Proportionality?

If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.

Given:

Total Baseball Caps= 30

Total amount of Cap= $240

let the number of caps sold be c.

Then, the equation is

30 c= 240

and, c= 240/30

c= 8

Hence, the constant of Proportionality is 8.

Which of the following equations have infinitely many solutions?
Choose all answers that apply:
46x - 23 = 46x + 23
-46x + 23 = 46x + 23
46x + 23 = 46x +23
-46x - 23 = 46x + 23

Answers

Answer:

46x + 23 = 46x +23

Step-by-step explanation:

46x - 23 = 46x + 23

Subtract 46x from each side

-23 = 23

This is not true so there are no solutions

-46x + 23 = 46x + 23

Add 46x to each side

23 = 96x +23

Subtract 23 from each side

0 = 96x

x=0 one solution

46x + 23 = 46x +23

Subtract 46x from each side

23 = 23

This is always true so there are infinite solutions

-46x - 23 = 46x + 23

add 46x to each side

-23 = 96x +23

subtract 23 from each side

-46 = 96x

x = -1/2

What are some possible solutions for the following inequality?

-3x+5x-2>-4x+1

Answers

x>1/2 is a solution

Answer:

Any value greater than 0.5.

Step-by-step explanation:

First, set the inequality to an equation and solve for x:

$-3x+5x-2=-4x+1\\2x-2=-4x+1\\2x-2+4x=-4x+1+4x\\6x-2=1\\6x-2+2=1+2\\6x=3\\(\frac{1}{6})6x=3(\frac{1}{6})\\x=\frac{1}{2}$

This is the value at which the inequality equals 0. To test the inequality and determine whether x is greater or less than $\frac{1}{2}$, choose any value of x that is easy to work with on either side of $\frac{1}{2}$:

For x=0:

-3(0)+5(0)>-4(0)+1

0>1 This is not a true statement. Therefore, x is not less than $\frac{1}{2}$.

For x=1:

-3(1)+5(1)>-4(1)+1

-3+5>-4+1

2>-3 This is a true statement. Therefore, x is any value greater than $\frac{1}{2}$.
