please someone help I know the answer but I don't know how to place it on the scales below. (15 Points)
guapka [62]

Given:

a. 35% of 150 g

b. 113% of $55

To find:

The correct values for the given blanks.

Solution:

a. 35% of 150 g

Here, the percent part is 35% and percent whole is 100%.

35% of 150 g is:

\dfrac{35}{100}\times 150=52.5

So, the number part is 52.5 g and the whole number is 150 g.

Therefore, the percent part is 35%, number part is 52.5 g and the whole number is 150 g.

b. 113% of $55 g

Here, the percent part is 113% and percent whole is 100%.

113% of $55 is:

\dfrac{113}{100}\times 55=62.15

So, the number part is $62.15 and the whole number is $55.

Therefore, the percent part is 113%, number part is $62.15 and the whole number is $55.

PLEASE HURRY!! 20 PTS!!

We have one of those equations already solved for y, so let's sub that one into the other one and solve the equation in terms of x only: 2x+( x^{2} -4x+3)=6.  We will simplify that and at the same time bring the 6 over by subtraction to get a polynomial set to equal 0 that we can factor.  x^{2} -2x-3=0.  We will factor that to get (x-3)(x+1) for x values of x = 3 and x = -1.  a above is the choice that has the x values we need, -1 and 3.

The length of a rectangular dog park is 50 feet. The width is half the length. Decide if each set of steps could be used to find
Leokris [45]

Answer:

4. Find the Width by dividing 50 by 2. Then double the length, double the width, and add the products to find the perimeter = Yes

Step-by-step explanation:

The length of a rectangular dog park is 50 feet. The width is half the length.

The formula for Perimeter is given as:

P = 2L + 2W

Length = 50 feet

Width = 50 feet/2

= 25 feet

P = 2(50) + 2(25)

P = 100 + 50

P = 150 feet

Hence, writing yes or no in front of each step in the options.

1. Find the Width by dividing 50 by 2. Then add the length and width and multiply the sum to find the perimeter = No

2. Find the Width by dividing 50 by 2. Then multiply the length by the width to find the perimeter. = No

3. Find the Width by dividing 50 by 2. Then add the length and the width to find the perimeter.= No

4. Find the Width by dividing 50 by 2. Then double the length, double the width, and add the products to find the perimeter = Yes

5. Find the Width by dividing 50 by 2. Then add the sum of each length and the sum of each width to find the perimeter = No

THE CORRECT STEP IN THE ABOVE OPTION IS OPTION 4
