95 x .35 = 33.25
95 - 33.25 = 61.75 (Sale Price)

To Find The Original Price, Use the formula S=P−PD, where S equals the sale price of the
item, P equals the original price of the item, and D equals the discount percent of the item.

55.5 = P -P(.75)
55.5 = P(1-.75)
55.5 = P(.25)
Divide Both Sides By .25 To Get P By Itself
222 = P

Take the percent discount and flip it out of 100% so if the discount is 20% flip it to 80% then make that a decimal so .80 and multiply the original price by the decimal you found so 95*.80 and that's your sale price.

Craig and Alissa are building a sandcastle on the beach. They each have a bucket. Craig's bucket holds 1/2 pound of sand and Ali

Nitella [24]

<h3>Amount of sand craig and Alissa collect together at one time is 1.4 pounds</h3>

Solution:

Given that,

Craig and Alissa are building a sandcastle on the beach. They each have a bucket

Craig's bucket holds 1/2 pound of sand and Alissa's bucket holds 9/10 pound of sand

Therefore,

$Craig\ bucket = \frac{1}{2}\ pound\\\\Alissa\ bucket = \frac{9}{10}\ pound$

How much sand can craig Alissa collect together at one time

Add both, we get

$Collect\ together = \frac{1}{2} + \frac{9}{10}\\\\Collect\ together = \frac{1 \times 5}{2 \times 5} + \frac{9}{10}\\\\Collect\ together = \frac{5}{10} + \frac{9}{10}\\\\Collect\ together = \frac{9+5}{10}\\\\Collect\ together = \frac{14}{10} = \frac{7}{5} = 1.4\\\\In\ mixed\ fractions,\\\\Collect\ together = 1\frac{2}{5}$

Thus, amount of sand craig and Alissa collect together at one time is 1.4 pounds

You are planning on using circles to compare the populations of California 37,691,000, Texas 25,675,000, and New York 19,465,000

Aneli [31]

The areas of the circle will represent the population, so:
Area = πr²

5² : 19,465,000
C² : 37,691,000

California circle radius = 6.96 cm

For Texas:
5² : 19,465,000
T² : 25,675,000

Texas circle radius = 5.74 cm

Order of Operations: BPEMDAS

Step-by-step explanation:

Step 1: Define

f(x) = 9(3)ˣ

x = -1

Step 2: Solve

Substitute: f(-1) = 9(3)⁻¹
Evaluate: f(-1) = 9(1/3)
Multiply: f(-1) = 9/3
Divide: f(-1) = 3

Museum passes cost $5 for adults and $2 for children. One day the museum sold 1820 passes for profit of $6106. How many of each

Mariulka [41]

1,500 children, and 320 adults

2X + 9100 - 5X = 6100
x = 1500 (children passes sold)

1820-1500 = 320 (adult)
