Answers
Answer:
Lindsey got 70% on this assignment.
Step-by-step explanation:
21 divided by 30 equals 0.7 which is 70% in percent form.
Answer:
She earned a seventy percent.
Step-by-step explanation:
You set the problem up like 21/30 = x/100.

From there, you divide each side by thirty and then you get x = 70.
And that brings you to 70 percent. Hope this helps!

Find the surface area of this right triangle

Answer:
144 square centimeters
Step-by-step explanation:
So the first triangle, which is on the side. We do 3 x 4, which is 12. We would normally divide it by 2 since it is a triangle, but since there is 2 triangles that are the same, we keep it 12. Next, we have the bottom rectangle. We do 4 x 11, which is 44. Next we do the top rectangle, 5 x 11, which is 55. Next we do the side rectangle, 3 x 11, which is 33.
Next we add all of these answers together!
12 + 44 = 56
56 + 55 = 111
111 + 33 = 144

Georgia has been saving her earnings from her lemonade stand. Georgia has 80 dollars to spend. If she buys a new hat for 22 dollars, how many bows can she buy with the remaining money if they cost 5 dollars each?
Answers
Answer:
Step-by-step explanation:
Because she bought a new hat for 22 dollars, subtract that from the 80 dollars.
1. 80-22=58
Next, each bow costs 5 dollars so you’ll have to see how many times 5 goes into 58 to get your answer.
2. 58/5= 11 with three dollars remaining.
That means Georgia can purchase 11 bows with the remaining money.

Organic Whole Wheat Flour Sells in bags Weighing 2.915 Kg A. How much flour is this when rounded to the nearest tenth B. How much flour is this when rounded to the nearest tenth Explain your thinking
Answers
Answer:
2.9 kg
Step-by-step explanation:
If you round 2.915 to the nearest tenth, it would be 2.9. this is because the number to the right of the 9 (1) is below 5.
The amount of flour after rounded to the nearest tenth will be 2.91 kg.
What is rounding off?Rounding numbers refers to changing a number's digits such that it approximates a value. The provided number is more simply represented by this value. For instance, 700,000 rather than 698,869 could be used to express a town's population.
Given that;
Organic Whole Wheat Flour Sells in bags Weighing 2.915 Kg.
Now,
Since, Organic Whole Wheat Flour Sells in bags Weighing 2.915 Kg.
We know that;
When we round to the nearest tenth we see the right digit of tenth place if it is less than 5 then write same as number but if the number is greater than 5 then add one on the tenth place number.
Hence,
The amount of flour after rounded to the nearest tenth = 2.9
Because, 1 < 5
Thus, The amount of flour after rounded to the nearest tenth = 2.9 kg

Erion plans to tile the floor of his kitchen. The kitchen is 11 feet by 15 feet. The tiles he will be using are square, measuring 8 inches on each side, and are sold in boxes that contain enough tile to cover 25 square feet. How many boxes of tiles must he order to complete the job?
Answers
Answer:
First, find the area for the kitchen floor: 16.5*15=247.5 squared feet
Then find the area for one tile: 0.5*0.5=0.25 squared feet
Finally, divide the mayor area between the minor: 247.5/0.25= 990 tiles.
Also you can do it in this another way:
First, divide length of the kitchen floor between the length of one tile: 16.5/0.5=33
Then, do the same for the height: 15/0.5=30
Finally multyply both results: 33*30= 990 tiles.

You should eat at least 2,000 calories per day. Today, you have eaten a total of 1,200 calories and you plan to eat pizza for dinner. If each slice of pizza is 352 calories. How many slices of pizza should you eat for dinner?
Answers
Answer:
Step-by-step explanation:
We know you need at least 2,000 calories, and we have eaten 1,200 of those. To find how many we have left we need to subtract the calories we have eaten from our goal (Shown below)
\(2000 - 1200 = 800\) calories we have left.
Now we know each slice of pizza is 352 calories, and we need 800 calories. If we divide 800calories remaining by 352calories a slice, we can find how many slices of pizza we need to eat.
\(800 / 352 = 2.27\) slices of pizza needed to meet the minimum calorie requirement.
Good luck getting exactly 2.27 slices of pizza. Because we need a minimum of 2.27 slices, we should round up to 3 slices to get all the calories needed for the day.
Answer: 3 slices of pizza for dinner

Mrs. Jones wants to paint the back wall of her classroom light blue. If the dimensions of the wall is 20 feet by 12 feet, how much paint will she need to paint her classroom wall? Round to the nearest tenth if necessary.
Answers
Answer:
The total area of the back classroom wall is (20ft x 12ft) = 240ft²
The paint coverage is usually rated by area coverage. For example, one gallon of paint is expected to cover 400 ft².
Assuming a gallon of paint will cover 400ft², she will need (240ft²/400ft²) = 0.6 gallon of paint to cover the entire wall.
Mrs. Jones will need 0.6 gallon of paint to paint the back classroom wall.
