Answer:
a. 270 square feet
b. 3.75 inches by 4.5 inches
c. $10,260
Step-by-step explanation:
A rectangular room measures 15 feet by 18 feet. It is going to be carpeted with carpeting that sells for $38 per square foot.
a. What is the area of the room in square feet?
Area of a rectangular room = Length × Width
Length = 15 feet
Width = 18 feet
Area of the room = 15 feet × 18 feet
= 270 square feet
b. If the room is drawn to 1/4 inch represents 1 foot scale, give the dimension of the room in inches on the scale drawing. Please write in decimal form to the nearest hundredth.
From the above question:
1/4 inch = 1 foot
Length = 15 feet
Hence:
1 foot = 1/4 inch
15 feet = x inch
Cross Multiply
x = 15 × 1/4 inch
x = 3.75 inches
For the Width = 18 feet
Hence:
1 foot = 1/4 inch
18 feet = x inch
Cross Multiply
x = 18 × 1/4 inch
x = 4.5 inches
Therefore, the dimensions of the room in inches is
3.75 inches by 4.5 inches
c. What is the total price for the carpeting? _
From the above question, we know that: A square foot of carpet is sold for $38
The area of the room is 270 square feet
Hence:
1 ft² = $38
270 ft² = $x
Cross Multiply
1ft² × $x = 270 ft² × $38
$x = 270 ft² × $38/ 1 ft²
$x = $10,260
Therefore, the total price for the carpeting of the room is $10,260.

can you use the term parallelogram to describe a rectangle
Answer:
Yes. In order for a shape to be qualified as a parallelogram It has to have 4 main properties. Opposite sides are parallel. Opposite sides have to be congruent. The opposite angles are congruent. Consecutive angles are supplementary (adds to 180-degrees). A rectangle qualifies all of these properties for a parallelogram. Opposite sides are parallel which works for a rectangle since they never intersects with the oppposit line. Opposite sides are congruent or equal which is also true becuase when looking at any 2 opposite sides of a rectangle, its always gonna be equal. Opposite angles are congurent which is also true because their all 90 degrees all are equal. And finally consecutive angles add up to 180. Soncsuive int his case basically means the angle next to that angle but we don’t have to worry about that since all angles of a rectangle are 90 and 90+90=180 so it also DOES qualify for a parallelogram.

Answer:
x = 73 °
Step-by-step explanation:
A pentagon has a collective degree of 540
So to find x, you have to set up an equation:
x + 127 + 112 + 108 + 120 = 540
To solve:
Combine like terms
x + 467 = 540
Subtract 467 on both sides:
x = 540 - 467
x = 73

a recipe calls for 5/8 cup of sugar for every 5 teaspoons of vanilla. what is the unit rate in cups per teaspoon?
a) 3 1/8
b) 1/8
c) 8
d) 8/25
Answer:
b) 1/8
Step-by-step explanation:
5/8 ÷ 5 = 1/8
The unit rate in cups per teaspoon is 1/8 cup of sugar.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
5/8 cup of sugar=5 teaspoons of vanilla.
or, 5 teaspoons of vanilla = 5/8 cup of sugar
So, 1 teaspoon of vanilla = (5/8)/5 cup of sugar
(5/8)/5 = (5/8)*(1/5)
(5/8)/5 =1/8
So, 1 teaspoon of vanilla = 1/8 cup of sugar
Hence, the unit rate in cups per teaspoon is 1/8 cup of sugar.

While attending a major league baseball game, you think you can guess the
attendance within 10% of the actual value. If the announced attendance is
35,000, within what number of people would your guess have to be in order for you to support your claim?
Answer:
You would have to have guess a number larger than 31500 and smaller than 38500
Step-by-step explanation:
The answer will look something like
35000 +/- 10% (35000)
What that means is that the attendance would be smaller than 35000 or larger than 35000.
10% * 35000 = 10/100 * 35000 = 350000 / 100 = 3500
So you would have to estimate
35000 - 3500 ≤ attendance ≤35000 + 3500
31500 ≤ attendance ≤ 38500

Harriet had a remote control car every 4/15 of a second the remote control car travels 4/5 of a foot how many feet per second does the remote control car travel
Answer:
3 ft/s
Step-by-step explanation:
The rate or speed of the remote control car, v = distance/time
Now, the distance travelled by the remote control car = 4/5 of a foot = 4/5 × 1 ft = 4/5 ft and the time it takes to cover this distance is 4/15 of a second = 4/15 × 1 s = 4/15 s.
So, v = distance/time
= 4/5 ft ÷ 4/15 s
= 4/5 ft × 15/4 s
= 3 ft/s
