7¼ can be expressed as 29/4. 29/4 x 1/18 = 29/(4 x 18) = 29/72.
5 ÷ 8 = 0.625, which equals 62.5%. Rounding up gives us 63%.
First, we must calculate the area of the walls Amanda wants to paint. Two of the walls are 10 x 10 and two of the walls are 10 x 15: 2 (10 x 10) = 200 2 (10 x 15) = 300 So the total square footage of the walls is 500. If a half gallon of paint will cover 55 square feet, then each gallon will cover 110 square feet. Four gallons would only cover 440 square feet. Five gallons will cover 550 square feet, which will be enough for all 500 square feet of walls.
The prefix “milli-” means 1,000. There are 1,000 millimeters in 1 meter, so there are 5,000 millimeters in 5 meters.
If Kyra buys n pairs of shoes at a cost of $40 each, she pays $40n. Since she only has $300 to spend, $40n must be less than or equal to $300:
Remember your order of operations: Complete operations within parentheses first. Calculate exponents. Then multiply and divide in order from left to right. Then add and subtract in order from left to right. 2 − 8 ÷ (24 ÷ 2) = 2 − 8 ÷ (16 ÷ 2) = 2 − 8 ÷ 8 = 2 − 1 = 1
A pie chart represents percentages of a total, and would thus be the best graphic representation of a budget breakdown.
The smallest number is the greatest negative value: −1/4 (−0.25). The next smallest is −0.2 (−1/5). The largest value is π, or approximately 3.14.
When subtracting polynomials the first step is to distribute the negative sign through the parentheses. This changes the sign on each term inside the parentheses:
Use the First, Outside, Inside, Last (FOIL) approach to solve. x² +4x +4x + 4*4
Keeping the base and adding the exponents is how you multiply two powers with the same base.
Three lollipops are included with the total of 18 candy pieces. As a result, the likelihood of selecting one lollipops is 3/18, which may be expressed as 1/6.
There are a total of 4 x 5 = 20 possible combinations using the 4 shirts and one of the 5 ties.
You must deduct the sum she originally had ($1,000) from the sum she spent ($500). (Z).
2/3 are not on vacation if 1/3 are. 3/4 of the 2/3 who aren't on vacation are healthy. As a result, 2/3 x 3/4 are present at work (not absent due to illness or vacation) = (2/3)/(3/4)=6/12=1/2.
Add 0.05 to both sides. As a result, z=1/0.05=20.
The sides of a cube are all the same length (s). A cube has a volume of s x s x s. Thus, s in this instance equals 4 (4x4x4=64). Six squares, each with an area of s x s, make up a cube. As a result, a cube's surface area is 6 x s x s = 6 x 4 x 4 = 96.
42 inches = 3 1/2 feet x 12 inches per foot. 24 bricks equal 42 inches by 1.75 inches.
20% of $28 = 28×0.2=$5.60. The purchase price is then $28-$5.6, or $22.40.
2 1/2 x 60 = 150
384 miles/32 gallons is 12 gallons for the vehicle. Consequently, the tank will still contain 3 gallons (15 gallons – 3 gallons)
