What is the area of rectangle?Any shape's area can be calculated by counting how many unit squares will fit inside of it. A square with a side of 1 unit is referred to as a unit square in this context. Therefore, the quantity of unit squares that make up a rectangle's perimeter is its area.Alternately, the area of the rectangle is the area contained within the boundary of this shape. The unit-length tiles in your home are a good illustration of a rectangle form. By counting the number of tiles, you can quickly determine how much space the floor takes up. This will also enable you to calculate the rectangular floor's area.acc to our question-

A spinner with 9 equal sections is numbered 1 through 9. The probability of spinning a 3 is 1/9. What is the probability of not spinning a 3 is what
Answers
The probability of not spinning a 3 is 8/9
How to determine the probability that the number 3 is not spun?From the question, the given parameters are:
Number of sections = 9
Sections = Number 1 to 9
The probability of spinning a 3 = 1/9
The above probability can be represented as
P(3) = 1/3
The probability that the number 3 is not spun is the complement of the probability of spinning a 3
This is calculated as
P(3) + P(Not 3) = 1
Substitute the known values in the above equation So, we have the following equation
1/9 + P(Not 3) = 1
Evaluate the like terms
P(not 3) = 8/9
Hence, the probability is 8/9

The missing expression in step 2 should be [(6² + 2)/0.5] - 14.8 ÷ 8.
The missing expression in step 6 should be 76 - 1.85.
How to evaluate and solve the given expression?In order to evaluate this expression, we would apply the PEMDAS rule, where mathematical operations within the parenthesis are first of all evaluated, followed by exponent, and then multiplication or division from the left side of the expression to the right. Lastly, the mathematical operations of addition or subtraction would be performed from left to right.
For step 1, we have the following:
[(6² + 2)/|-0.5|] - 14.8 ÷ 8.
In step 2, we would take the absolute value of -0.5:
[(6² + 2)/0.5] - 14.8 ÷ 8.
Therefore, we would have the quantity of the sum of six squared (6²) plus two (2) divided by 0.25, minus 14.8 ÷ 8
In step 3, we would take the exponent of 6:
[(36 + 2)/0.5] - 14.8 ÷ 8.
In step 4, we would add 36 and 2 together:
[(38)/0.5] - 14.8 ÷ 8.
In step 5, we would divide 38 by 0.5:
76 - 14.8 ÷ 8.
In step 6, we would divide 14.8 by 0.5:
76 - 1.85
In step 7, we would subtract 1.85 from 76 as follows:
Solution = 76 - 1.85 = 74.15.

24. The height of an object varies directly with the length of its shadow. If a tree 8 feet tall casts a shadow 10 feet long, how long will be the shadow of a tree that is 12 feet tall?
Answers
Answer:
15 feet
Step-by-step explanation:
Given an 8' object casts a 10' shadow, you want to know the length of the shadow of a 12' object.
ProportionThe shadow length is proportional to the object length:
shadow/object = 10'/8' = s/12'
Multiplying by 12', we have ...
s = (12')(10/8) = 15'
The shadow of a tree 12 feet tall will be 15 feet long.

You and a friend go to Tacos Galore for lunch. You order three soft tacos and three burritos, and your total bill is $11.25. Your friend’s bill is $10.00 for four soft tacos and two burritos. How much do soft tacos cost? How much do burritos cost? Explain and show work
Answers
The cost of a soft taco is $1.25 and the cost of a burrito is $2.50.
Let the cost of a soft taco would be t and,
The cost of a burrito would be b
As per the given question, the equations would be as
3t+3b=11.25 ...(i)
4t+2b=10 ...(ii)
With the two equations in that form, an elimination solution is probably the simplest.
Multiply each equation by a constant so that the coefficients of b are opposite so that when the two equations are joined, b is eliminated.
-6t-6b = -22.50
12t+6b = 30.00
_____________
6t = 7.50
t = 7.50/6 = 1.25
Substitute the value of t = 1.25 in equation (ii), and solve for b
4(1.25)+2b=10
5+2b=10
2b=5
b=2.50
Thus, the cost of a soft taco is $1.25 and the cost of a burrito is $2.50.

You need two givens to use in the formula to solve for the third.
Formula
v = sqrt(2*g*h)
Givens
V = 136 ft/s
g = 32 ft/s^2
h = ?
Solution
v = sqrt(2*g*h) Put the givens into the formula.
136 = sqrt(2* 32 * h) Square both sides
136^2 = sqrt(2*32*h)^2 Expand
18496 = 64* h Divide by 64
18496/64 = 64*h/64
289 feet = h

This problem is solved using the Pythagorean theorem (a2+b2=c2). In this formula a and b are the legs of the right triangle while c is the hypotenuse.
Using the labels of our triangle we have:

Consider the number as x
Then the product of 6 and the square of a number = [tex]6x^2[/tex]
The product of 6 and the square of a number is increased by 5 times the number, the result is 4
Then the equation will be

[tex]6x^2[/tex] + 5x - 4 = 0
We have to solve the quadratic equation
Split the middle terms
[tex]6x^2[/tex] + 8x - 3x -4 = 0
2x(3x+4) -1(3x+4) = 0
(2x-1)(3x+4)= 0
Then the value of x will be
2x- 1 = 0
2x = 1
x = 1/2
Similarly
3x+4 = 0
3x = -4

Answers
The slope of the given graph x^2 = ln (xy) at the point (1, e) is e
We have been given a graph x^2 = ln (xy) and a point (1, e)
Differentiate the given graph on both sides
d/dx x^2 = d/dx (ln (xy))
⇒ 2x = 1/xy × d/dx (xy)
⇒ 2x × xy = x.dy/dx + y.dx/dx
⇒ 2x^2y = x.dy/dx + y
⇒ 2x^2y = x.dy/dx + y
⇒ 2x^2y - y = x.dy/dx
⇒ (2x^2y - y)/x = dy/dx … (1)
The slope at the point (1, e)
m = dy/dx at x = 1, y = e
Substitute the values in Equation (1)
⇒ m = (2(1)^2 (e) - e)/1
