there is a rectangle made up of 18 small squares and 14 of them are shaded in what is the percentage of the shaded squares
Answers
77.78%
1) Considering that this rectangle is made up of 18 squares
2) Then we can solve it by setting a proportion:
18 --------------- 100%
14 ---------------- x
Cross multiplying it, since it is a proportion we have:
18x = 1400 Divide both sides by 32
x =77.78
3) So we can say that the shaded squares represent 77.78% of the rectangle.

Answers
The equation that represents the quotient of -100 and twice 10 equal to -5 is; -100 ÷ 2(10) = -5
How to solve algebra expressions?The quotient of an algebraic operation is defined as a result that is obtained by dividing one quantity by another.
We are told that the quotient of -100 and twice 10 is equal to -5. Thus, we can express the given expression as;
-100 ÷ 2(10) = -5
This is because quotient means answer that is produced from dividing 2 numbers and since the product is a whole number and not a proper fraction, then it means that the larger number will be the numerator while the smaller number will be the denominator.

Answers
In linear equation, the amount of money paid for the 10-day rental will be $ 1860.
What is a linear equation?
A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.
The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
The amount of money for a 10-day rental will be calculated as,
A = 460+140d
A = 460+(140 x 10)
A = 460 + 1400
A = 1860
Therefore, the amount of money paid for the 10-day rental will be $ 1860.

How much will it cost to carpet the room? Show your work. (c) Furniture covers 25% of the floor. How many square feet of carpet are covered by furniture? Show your work.
Answers
Given:
\(\begin{gathered} \text{ Base }b_1=23\text{ ft, }b_2=35\text{ ft} \\ \text{ Height,}h=28\text{ ft} \end{gathered}\)Required: Area of the room, cost to carpet the room and square feet of carpet are covered by furniture
Explanation:
a) Plug the values into the formula
\(A=\frac{1}{2}h(b_1+b_2)\)gives
\(\begin{gathered} A=\frac{1}{2}\cdot28\cdot(23+35) \\ =812\text{ ft}^2 \end{gathered}\)Area of the room is 812 square feet.
b) Cost of carpet per square foot = $8.30
Cost to carpet the room
\(\begin{gathered} =\text{ Area of the room}\times\text{ Cost of carpet per square foot} \\ =812\times8.30 \\ =6739.6 \end{gathered}\)Cost to carpet the room is 6739.6 dollars.
c) Area of the furniture covers = 25% of Area of the room
\(\begin{gathered} =\frac{25}{100}\cdot812 \\ =203 \end{gathered}\)So, 203 square feet of carpet are covered by furniture.
Final Answer: a) Area of the room is 812 square feet.
b) Cost to carpet the room is 6739.6 dollars.

Red=

purple=
Answers
The central angles for each category are approximately: Red: 100°, Blue: 150°, Green: 50° and Purple: 60°
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
To find the central angle of each category, we first need to calculate the total number of people:
Total = 20 + 30 + 10 + 12 = 72
Next, we can calculate the percentage of people who prefer each color:
Red: 20/72 = 0.278, or 27.8%
Blue: 30/72 = 0.417, or 41.7%
Green: 10/72 = 0.139, or 13.9%
Purple: 12/72 = 0.167, or 16.7%
To find the central angle for each category, we can multiply the percentage by 360°:
Red: 0.278 × 360° = 100.08°
Blue: 0.417 × 360° = 150.12°
Green: 0.139 × 360° = 50.04°
Purple: 0.167 × 360° = 60.48°
Therefore, the central angles for each category are approximately:
Red: 100°, Blue: 150°, Green: 50° and Purple: 60°

PLEASE ANSWER ASAP!!Find a rational function that might have the given graph. (More than one answer might be possible.)
Answers
Answer:
The rational function that might have the given graph is \(y = - \frac{x}{(x+1)\cdot (x-1) }\).
Step-by-step explanation:
This graph shows a rational function whose numerator is a first order polynomial and denominator is a second order, due to the presence of vertical asymptotes at \(x = -1\) and \(x = 1\). The lead coefficient of the numerator must be 1, since horizontal asymptote must be \(y = 0\) and intercept must be \(0\), since \(y(0) = 0\).
Then, we conclude that a rational function that might have the graph is:
\(y = - \frac{x}{(x+1)\cdot (x-1) }\) (1)
We present the proof that given function is appropriate.

Find
the most economical car
Solution
The attached spreadsheet shows the costs of repairs, insurance, and gas for each of the cars, using the cost factors described in the problem statement. (Numbers are displayed rounded to dollars.)
Mileage each year is assumed to be 150,000/8 = 18,750.
The "present value" line shows the present (year 0) value of the listed costs. The present value is the sum of values divided by 1.05^(year number). It is calculated using the spreadsheet NPV function.
The green total is the sum of present values to its right and the initial cost. The end value is subtracted after it is discounted by 1.05^8.
The Japanese car has the lowest present value.

The coordinates of the midpoints of the four sides of a square are S(-4,11), Q(2,5), U(-4,-1), A (-10,5)
Answers
The perimeter and area of the square are; 24√2 units and 12 units² respectively
Given the coordinates of the midpoints of the four sides of a square are S(-4,11), Q(2,5), U(-4,-1), A (-10,5)
But since we have the midpoints of all the sides, we can assume they're equidistant from one another since the figure is a square.
SQ = √(x₂ - x₁)² + (y₂ - y₁)²
SQ = √(2 - (-4)² + (5 - 11)²
SQ = 6√2
Let's find QU
QU = √(-4 - 2)² + (-1 - 5)²
QU = 6√2
Let's find UA ;
UA = √(-10 - (-4))² - (5 - (-1)²
UA = 6√2
And the distance AS = 6√2
The perimeter of the square = 4 (6√2)
Perimeter = 24√2 units
The area of the square = l²
Area of the square = (6√2)²
Area of square = 12 units²

Answers
Answer:
b=7 & c=7√2
Step-by-step explanation:
b=7 as it is an isosceles triangle
now using Pythagoras theorem,
(c)^2= (7)^2+(7)^2
⇒(c)^2= 49+49
⇒(c)^2= 98
⇒c= √98
⇒c=7√2
Answer:
b = 7c = 7√2Step-by-step explanation:
You want the missing side lengths in an isosceles right triangle with one side given as 7.
Isosceles right triangleThe two congruent acute angles tell you this right triangle is isosceles. That means sides 7 and b are the same length:
b = 7
The hypotenuse of an isosceles right triangle is √2 times the side length:
c = 7√2
__
Additional comment
You can figure the hypotenuse using the Pythagorean theorem if you haven't memorized the side relations of this "special" right triangle.
c² = 7² + b²
c² = 7² +7² = 2·7²
c = √(2·7²) = 7√2
The side length ratios for an isosceles right triangle (angles 45°-45°-90°) are 1 : 1 : √2.
The other "special" right triangle is the 30°-60°-90° triangle, which has side length ratios 1 : √3 : 2.
