suface area of cuboid 9 5 4
The cuboid in question has a surface area of 202 square units.
We must sum together the areas of all six faces to determine a cuboid's surface area.
The dimensions of the given cuboid are:
length (l) = 9 units
width (w) = 5 units
height (h) = 4 units
The area of each face is given by:
Top and bottom faces:\(lw = 9 * 5 = 45\) square units each
Front and back faces: \(lh = 9 *4 = 36\) square units each
Left and right faces: \(wh = 5 * 4 = 20\) square units each
Therefore, the total surface area of the cuboid is:
\(2(lw + lh + wh) = 2(45 + 36 + 20)\\ = 2(101) \\= 202 \ square \ units\)
Hence, the surface area of the given cuboid is 202 square units.

Two hundred people were asked if they had read a book in the last month. The accompanying contingency table, cross-classified by age, is produced.
Under 30 30+
Yes 76 65
No 24 35
The probability that a respondent read a book in the last month and is at least 30 years old is the closest to
A. 0.33
B. 0.88
C. 0.46
D. 0.12
The answer of the given question is option (A) which is 0.33 which is about reading a book in the last month by 200 hundred people.
What is Age?Age is defined as a time length that a person or thing has existed. It is to define as at how old a person or thing in a particular time.
To solve the question, we need the intersecting cell of Yes and 30+
\(n(Yes\ n\ 35+) = 65\)
The probability is then calculated as follows:
\(P(Yes\ n\ 35+)\) = \(\frac{n(Yes\ n\ 35+)}{65}\)
Where Total = 200
\(P(Yes\ n\ 35+)\) = \(\frac{65}{200}\)
\(P(Yes\ n\ 35+)\) = \(0.325\)
From the list of given options; (A) is the closest to 0.325.
So Answer is 0.33

The length of a rectangle is 6 times its width. If the perimeter of the rectangle is 98in , find its area.
Answer:
294in²
Step-by-step explanation:
Let the width be x
Perimeter = 2(length+width)
98 = 2(6x + x)
49 = 6x + x
49 = 7x
7 = x
The width is 7 and the length is 7 x 6 = 42
Area = length × width
42 × 7 = 294in²
The ratio of the number of men to the number of women in a sports club is 5:2.
After 63 men and 12 women quit the club, the ratio of the number of men to the number of women became 7:4.
How many members did the club have in the beginning?
Let the number of men and the number of women in the beginning be x and y
Now,\(\sf \frac{x} {y} =\frac{5}{2} \\\\\sf
=2x=5y \\\\\sf
=x=\frac{5y}{2}\)
Now, In 2nd case,
No. Of men=x-63 and no. Of women =y-12
Now,the ratio becomes\( \frac{x-63}{y-12}=\frac{7}{4} \\\\\sf
=4(x-63)=7(y-12) \\\\\sf
=4x-252=7y-84 \\\\\sf
Putting,\:x=\frac{5y}{2}\:in\: 4x-252=7y-84\:we\: get, \\\\\sf
10y-252=7y-84 \\\\\sf
=10y-7y=252-84 \\\\\sf
=3y=168 \\\\\sf
=y=56 \\\\\sf
=\boxed{Y=56}
\)
Now,we have, 2x=5y
Putting the value of Y=56 in 2x=5y,we get,
\(\sf 2x=5\:x\:56 \\\\\sf
x=\frac{5\:x\:56}{2} \\\\\sf
x=\frac{5\:x\: \cancel{56}\:\:28}{ \cancel{2}} \\\\\sf
=x=5\: x\: 28 \\\\\sf
x=140 \\\\\sf
\boxed{x=140}

Hence, the number of men was 140 and the no. of women was 56

the figure is cut into 12 equal pieces. shade 2/3 of the figure
Answer:
So you shade 8 parts in and the remaining is 4 so that the other 1/3 of 2/3
Answer
so basically you're asking shade 2/3 out of 12 equal pieces
so lets do 12 divided by 3 witch is four
so there would be 3 parts that have 4 pieces, and 4 times two is eight, so shade in 8 pieces :0 :)
The builder recommends to Siya that he buys 10% more tiles than required in case of breakages. the tiles he likes are R234 for a box of 6 tiles. How much will Siya spend on tiles?
The amount Siya will spend on tiles is given by the expression (1.1 x T / 6) x R234, where T represents the required number of tiles. To calculate the amount Siya will spend on tiles, we need to determine the number of boxes of tiles he needs to purchase and then multiply it by the price per box.
First, we need to determine the number of tiles required. Let's assume the required number of tiles is represented by the variable "T."
Since the builder recommends buying 10% more tiles in case of breakages, Siya needs to purchase 110 percentage of the required number of tiles. This can be calculated as:
110% of T = 1.1 x T
Next, we need to convert the number of tiles into the number of boxes required. We know that one box contains 6 tiles, so the number of boxes Siya needs to purchase is:
Number of boxes = (1.1 x T) / 6
Finally, we can calculate the total cost by multiplying the number of boxes by the price per box:
Total cost = (1.1 x T / 6) x R234
Please note that without knowing the specific number of tiles required (T), we cannot provide an exact amount Siya will spend.

Solve the system of equations by substitution.
Given equations:
x + y = 15 . . . . . . . . (1)y = 4x . . . . . . . . . . . (2)To find :
value of xvalue of yPut value of y of second equation (i.e y = 4x) in equation one (i.e x + y = 15)
➞ x + y = 15
➞ x + 4x = 15
➞ 5x = 15
Divide both LHS and RHS by 5
➞ (5x)/5 = 15/5
➞ x/1 = 3/1
➞ x = 3
Now put value of x in equation 2
{Note : value of x can be inserted both in equation 1 and 2}
➞ y = 4x
➞ y = 4 × 3
➞y = 12
Verification :
put value of x and y in equation 1 :
x + y = 1512 + 3 = 1515 = 15LHS = RHS
hence verified !
put value of x and y in equation 2 :
y = 4x12 = 4 × 312 = 12LHS = RHS
hence verified !
∴ Value of x and y is 3 and 12 respectedly .
REQUIRED ANSWER :
(x , y) = (3 , 12)
Answer:
(3, 12)
Step-by-step explanation:
Given equations:
Equation 1: x + y = 15Equation 2: y = 4xSubstitute Equation 2 into Equation 1 and solve for x:
⇒ x + 4x = 15
⇒ 5x = 15
⇒ x = 15 ÷ 5

What is an equation of the line that passes through the point (6,-4)(6,−4) and is perpendicular to the line 2x-y=52x−y=5?
The line that connects the coordinates (6, 4) and is perpendicular to the line 2xy=5 has the equation =y=1/2x-1.
What are straight-line equations?The general equation for every straight line is y = mx + c, where m is the gradient (or degree of steepness) of the line and c is the y-intercept (the point in which the line crosses the y-axis).
The variables x and y are related to coordinates on the line in the linear equation y = mx + c.
The formula y = mx + c yields a result for y when we enter a value for x.
As y depends on the value of x, it follows that x is an independent variable and y is a dependent variable.
According to our question-
a line equation that is perpendicular to the line 2xy=5 and passes through the point (6, 4)
The slope of the given equation 2x-y=5 is first determined.
The line's equation is y=mx+b. where'm' represents the slope
Hence, The line that connects the coordinates (6, 4) and is perpendicular to the line 2xy=5 has the equation =y=1/2x-1.

A common aspect ratio for computer screens today is width : height = 16 : 9. The advertised size of a screen is given by the measure of its diagonal. Measure the width, height, and diagonal of at least three screens (computers, tablets, phones) in your home. Are they similar? How do you know? Are any of your screens congruent? If so, what postulates prove it? List your measurements and describe your findings carefully.
Please follow these guidelines for your discussion posts:
Write at least 150–300 words.
A common aspect ratio for computer screens is 16:9, which means that for every 16 units of width, there are 9 units of height. This aspect ratio is also used on many televisions and mobile devices.
How to explain the ratio?If a screen has an aspect ratio of 16:9, the width and height will be similar on all screens with this aspect ratio. However, the diagonal measurement will vary depending on the size of the screen.
Congruent screens are two or more screens that have the same dimensions. Two screens are congruent if and only if corresponding sides are equal and corresponding angles are equal. This can be proven using the postulates of congruence, such as the SSS (Side-Side-Side) postulate or the SAS (Side-Angle-Side) postulate.

he radius of a circle is tripled. Which of the following describes the effect of this change on the area? The area is multiplied by 1/9 . The area is multiplied by 9. The area is multiplied by 3. The area is multiplied by 1/3.
Tripling the radius of a circle results in a nine-fold increase in its area.
The radius of a circle is a critical component in determining its size. Tripling the radius of a circle means that the size of the circle has increased three times its original size.
The area of a circle can be calculated using the formula
=> A = πr²,
where A represents the area of the circle, π is Pi, and r is the radius. When the radius of a circle is tripled, the value of r becomes 3 times its original value, meaning the formula becomes
=> A = π(3r)² = π * 9r² = 9πr².
Therefore, the new area of the circle is nine times the original area of the circle.
