10 in
Answer: 800
Step-by-step explanation:
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
The surface area of the figure is 40 + 5π.
What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:
Area = Length x width
We have,
From the figure,
We have a semicircle and a rectangle.
Now,
Diamter = 10 in
Radius = 5 in
Circumference = 2πr
Semicircle circumference = πr
Now,
The surface area of the figure.
= 15 + 10 + 15 + πr
= 40 + 5π
Thus,
The surface area of the figure is 40 + 5π.

Answer:
D ; y = (4/3)x + 2
Step-by-step explanation:
The general form of the equation of a straight line is;
y = mx + b
where m is the slope and b is the y-intercept
Now, let us represent the given equation in this general form
We have this as;
4y= -3x + 12
divide through by 4
y = -3/4x + 3
Now, the slope of this equation is -3/4
Mathematically, when two lines are perpendicular, the product of their slopes is -1
let us have the slope of the second equation as m2
-3/4 * m2 = -1
-3m2 = 4 * -1
m2 = -4/-3
m2 = 4/3
so, the equation that is perpendicular will have its slope as 4/3
Looking through the options given as we have the equations in the general form, the equation D is the correct answer
D ; y = (4/3)x + 2

Miguel compró 6 azulejos cuadrados cuya área es de 49 cm^2 cada uno y los ubicó en dos columnas de tres azulejos en la pared. ¿Cuál es el perímetro del rectángulo formado por estos azulejos en dicha disposición?
Answer:
the perimeter of the rectangle is 70 cm
Step-by-step explanation:
The computation of the perimeter of the rectangle is given below:
first we determine the side of each tile i.e.
l² = A
l² = 49cm²
l = √49cm²
l = 7cm
now we calculate the perimeter i.e.
P = 2 (3 (7cm) + 2 (7cm))
= 2 (21cm + 14cm)
= 2 (35cm)
= 70cm
Hence, the perimeter of the rectangle is 70 cm

A movie theater sells popcorn in bags of different sizes. The table shows the volume of popcorn and the price of the bag. If the theater wanted to offer a 60-ounce bag of popcorn, what would be a good price? Explain your reasoning
Answer:
For a volume of 60 ounces, the appropriate price is $16
Step-by-step explanation:
Firstly, we need to determine the relationship between volume of popcorn and the price of bag.
Let us try and see if there is a linear relationship
A linear model is of the form ;
y = mx + b
where m is the slope and b is the y intercept
While the price represents the y axis values, the volume represents the x axis values
For the slope;
m = (y2-y1)/(x2-x1)
m = (13.6-11)/(48-35) = 2.6/13 = 0.2
So we have the slope value as 0.2
the equation is;
y = 0.2x + b
to get b, substitute any value of (x,y)
6 = 0.2(10) + b
6 = 2 + b
b = 6-2 = 4
If we had substituted (20,8)
8 = 0.2(20) + b
8 = 4 + b
b = 4
if (48,13.6)
13.6 = 48(0.2) + b
13.6 = 9.6 + b
b = 13.6-9.6
b = 4
Hence we have established linear relationship between the volume in ounces and the price in $
So we have this as
Price = 0.2(volume) + 4
So for volume of 60 ounces;
Price = 0.2(60) + 4
price = 12 + 4
price = $16
The reason why this is appropriate is because it follows the rule of the established linear relationship
Answer:
$16

What is a transformation of geometry?A spatial transformation is each mapping of feature shapes to itself, and it maintains some spatial correlation between figures.
Rotation does not change the size and shape of the geometry. But change the orientation of the image.
The pentagon is shown.
The angle of rotation of the pentagon such that the pentagon will remain in the same position.
Then the angle of the rotation is given as,
⇒ 360° / n
Where n be the number of the sides of the polygon.
In pentagon, the number of the sides will be 5.
Then the angle of the rotation will be
⇒ 360° / 5
⇒ 72°
Thus, the angle of the rotation will be 72°
Then the correct option is B.

Martha conducts aerobics three times a week in her home in the first group there are 19 members in the second 22 and the third 14 how many people attend aerobics at Martha’s althougher
Answer: 55 people attend aerobics at Martha’s altogether
Step-by-step explanation:
Martha conducts aerobics three times a week in her home.
Number of members in first group = 19 members
Number of members in second group = 22 members ; and
Number of members in third group = 14 members
To find the number of people who attended aerobics we have to add the number of members in all tge three groups.
So, number of people who attended aerobics at Martha’s altogether = 19 + 22 + 14 = 55 members

What is the value of the expression 10-1/2^4x48
Answer:
7
Step-by-step explanation:
g(x)=3x+2 and h(x)=ax+B
where a and b are constants
h(4)=22
g^-1(14)=h(1)
find the value of a and the value of b
Answer:
a=6
b=-2
Step-by-step explanation:
You can use the hint provided on the mathswatch question page, I've attached it below
step 1
h(4) = ax+b = (ax4)+b = 4a+b
it is given in the question that h(4)=22, therefore 4a+b=22
step 2
work out the equation for inverse g
g^-1(x) = [tex]\frac{x-2}{3}[/tex]
step 3
input 14 into the equation in place of x to find g^-1(x)
[tex]\frac{x-2}{3} =\frac{14-2}{3} =\frac{12}{3} =4[/tex]
so, g(x)^-1=4
step 4
find h(1):
h(1) = (ax1)+b = a+b
so, h(1)=a+b
step 5
a+b=4 (as it is given in the question that g^-1(14) is equal to h(1))
step 6
Now you have two simultaneous equations:
4a+b=22
a+b=4
then, solve for a:
4a+b=22
- a+b=4
3a=18
a=6
then, input answer for a into either equation (I've gone with the a+b=4 equation):
6+b=4
-6 - 6
b=-2

Convert to percentages to understand the question better:
3/4 = 75%
4/5 = 80%
What is 80% of 75%?
Convert the percentages to decimals:
75% = 0.75
80% = 0.8
Calculate:
0.8 × 0.75 = 0.6
Convert back to original problem's format (fraction):
0.6 = 60% = 6/10 = 3/5

Answer: A) 20.9 ; B) 34years
Step-by-step explanation:
Given the following :
AGE (X) - - - - - - - 19 - -20 - - - 21 - - - 22 - - - 23
FREQUENCY (F) - 2 - - 3 - - - - 1 - - - - 4 - - - - 1
A)
MEAN(X) = [AGE(X) × FREQUENCY (F)] ÷ SUM OF FREQUENCY
F*X = [(19 * 2) + (20 * 3) + ( 21 * 1)+(22 * 4)+(23 * 1)]
= 38 + 60 +21 + 88 + 23 = 230
SUM OF FREQUENCY = 2 + 3 + 1 + 4 + 1= 11
MEAN(X) = 230 / 11
X = 20.9
B)
WHEN A NEW PLAYER WAS ADDED :
MEAN (X) = 22
Let age of new player = y
Sum of Ages = 19 + 19 +20 + 20 + 20 + 21 + 22 + 22 + 22 + 22 + 23 + y
Number of players = 11 + 1 = 12
Mean(x) = sum of ages / number of players
New mean (x) = 22
x = (230 + y) / 12
22 = (230 + y) / 12
Cross multiply
264 = 230 + y
y = 264 - 230
y = 34 years
