D. 12 square units
Therefore , the solution to the given problem of surface area comes out to be 24 square unit.
What does surface area is exactly?Shape is a unit used to describe how much overall space a material's surface occupies. A three-dimensional shape surface area is equal to the sum of its surroundings. The overall surface coverage of a multi shape is referred to as surface area. The volume of water of a cube featuring five rectangular faces can be calculated by adding up each face's specific area. As an alternative, you can identify the box's measurements using the formula below: Surface (SA) is equal to two times two times two.
Here,
The presented parallelogram has a height of 5-2 = 3 units.
The given parallelogram's basis is comprised of => 7 -(-1) units => 8 units.
As a result, the supplied parallelogram has a surface area of 8 * 3 = 24 square units.
As a result, 24 square units are required to solve the given area problem.

4 A roll of paper is shown below.
Tube
About how much cardboard is needed to make the inner tube for a roll of paper if the tube
has a diameter of 4.5 cm and is 24 cm long?
F 339 cm2
G 679 cm2
H 371 cm2
J
382 cm2
Answer:
339 cm²
Step-by-step explanation:
Using the relation for the surface area of a cylinder :
A = 2πrh
r = Radius = diameter / 2 = 4.5 / 2 = 2.25 cm
Height, h = 24 cm
A = 2 * 22/7 * 2.25 * 24
A = 339.29200 cm²
Surface Area =339 cm²
About 339cm³ of cardboard will be needed for the inner tube.
To make inner tube card board needed is 339 cm² of the material.
What is Surface area ?The surface area of a solid object is a measure of the total area that the surface of the object occupies.
Here, diameter = 4.5 cm
then, radius = 4.5/2 = 2.25 cm
height = 24 cm
Surface area = 2πrh
= 2 X 3.14 X 2.25 X 24
= 339.12 cm²
Thus, to make inner tube card board needed is 339 cm² of the material.

Which function has a greater y-intercept?
Answer:
Option C, both functions have an y-intersect equal to 2.
Step-by-step explanation:
When we have a function f(x), the y-intercept is the value f(0). This is the point where the graph of the function intersects the y-axis.
Then, for f(x) = -x^2 + 5*x + 2
The y-intercept is:
f(0) = -0^2 + 5*0 + 2 = 2
f(0) = 2
And for g(x) we do not have the equation, but we have the graph, so we can just look at which value of y does the graph intersects the y-axis.
We can see that the graph intersects the graph at y = 2
Then the y-intersect is: g(0) = 2
So both functions have the same y-intersect. Then the correct option is C.

Answer:
1193.2 sq. in.
Step-by-step explanation:
SA = LA + 2B
where LA is the lateral area and B is the area of the base (circle)
B = πr^2 = 3.14(10)^2 = 3.14(100) = 314
Area of 2 Bases = 2 (314) = 628
LA = Ch where C is the circumference of the base
LA = πdh = 3.14(20)(9) = 565.2
SA = 628 + 565.2 = 1193.2 sq. in.

Answer:
5cm
Step-by-step explanation:
Given data
Length= 3cm
Width= 4cm
Applying Pythagoras theorem
z^2= x^2+y^2
z^2= 3^2+ 4^2
z^2= 9+16
z^2= 25
square root both sides
z= √25
z= 5cm
Hence the diagonal is 5cm

(1
*
Answer:
3a²b
Step-by-step explanation:
The product of two algebraic
terms is 6a3b2. If one of the terms is
2ab, find the other term.
Let us represent
First term = a
Other term = b
a × b = 6a³b²
a = 2ab
b = ?
b = 6a³b²/a
b = 6a³b²/2ab
b = 6a³b²/2a¹b¹
b = (6 ÷ 2) × a^3 - 1 × b ^2 - 1
b = 3a²b
Therefore, the other term = 3a²b

At your local store, you are given a coupon for 20% off any store item purchased on Monday. When you return to your store, you notice that an item (normal price = $50) is on clearance for 40% off. You are allowed to use the coupon on the clearance item. How much should you pay for the item? Should it be 60% off of the normal price?
Answer:
$24
no, it is 48% off normal price
Step-by-step explanation:
clearance price = normal price - value of the 40% discount
value of the 40% discount = 0.4 x $50 = $20
Price = $50 - $20 = $30
final price = clearance price - value of 20% coupon
value of 20% coupon = 0.2 x $30 = $6
final price = $30 = $6 = $24
total value off normal price = $24 /$50 x 100 = 48%
Joseph made a scale drawing of an Italian restaurant. The scale he used was 1 millimeter : 6 meters. The restaurant's kitchen is 24 meters long in real life. How long is the kitchen in the drawing
Answer:
4mm
Step-by-step explanation:
Joseph made a scale drawing of an Italian restaurant. The scale he used was 1 millimeter : 6 meters.
From the above question, our scale factor is given as:
1 millimeter : 6 meters.
1 mm = 6 m
Which also means
6m = 1 mm
The restaurant's kitchen is 24 meters long in real life. How long is the kitchen in the drawing?
Hence, we can calculate this as
6m = 1 mm
24 m = x mm
Cross Multiply
6 m × x mm = 24m × 1 mm
x mm = 24m × 1 mm/6m
x mm = 4 mm
Therefore, the length of the kitchen in the drawing is 4mm

Calcula la diagonal de un rectángulo cuyos lados tienen las siguientes medidas.
a. 5 dm y 4 dm
b. 8 cm y 6 cm
Las longitudes de las diagonales son √41 dm y 10 cm respectivamente
La medida de la diagonal de un rectángulo: de lado l1 y l2 es igual a
d² = (l1)² + (l2)²
La diagonal entonces es: utilizamos la fórmula dadas para los lados dados y aplicando raíz en la ecuación
A. 5dm y 4dm
d = √((5 dm)² + (4 dm)²) = √(25 + 16) dm = √41 dm
B. 8cm y 6cm
d = √((8 cm)² + (6 cm)²) = √(64 + 36) cm = √100 cm = 10 cm .

Hannah has a bag containing 2 Red, 4 purple, 4 Blue and 2 Green
marbles that all are the same size and shape. What is the
probability of randomly choosing a Red marble replacing it, and
then randomly choosing a Blue marble?
Answer:
1/18
Step-by-step explanation:
there are 12 marbles in the bag
P(choose red) = 2/12 = 1/6
P(choose blue after replacement) = 4/12 = 1/3
P(choose red, then blue with replacement) = (1/6)(1/3) = 1/18

Answer:
54
Step-by-step explanation:
3*6*3=54
The solution is Option G.
The number of ways of choosing exactly 1 pair of shoes, 1 pair of pants, and 1 shirt is given by combination C = 54 ways
What are Combinations?The number of ways of selecting r objects from n unlike objects is:
ⁿCₓ = n! / ( ( n - x )! x! )
where
n = total number of objects
x = number of choosing objects from the set
Given data ,
Let the number of ways of choosing exactly 1 pair of shoes, 1 pair of pants, and 1 shirt be C
Now , the equation will be
The total number of shoes = 3 pairs
The total number of pants = 3 pairs
The total number of shirts = 6 shirts
And , the number of ways of choosing exactly 1 pair of shoes, 1 pair of pants, and 1 shirt is calculated by Combination , where
The number of ways of selecting 1 pair of shoes = ³C₁
The number of ways of selecting 1 pair of pants = ³C₁
The number of ways of selecting 1 shirt = ⁶C₁
So , the total number of ways = ³C₁ x ³C₁ x ⁶C₁
On simplifying the equation , we get
The total number of ways C = 3 x 3 x 6
The total number of ways C = 54 ways
Hence , the combination is C = 54 ways

The measure of an angle is 50°.what is the measure of its complementary angle
Answer:
If "x" is the degree measure of the given angle, then the measure of its complement is (x+50) degrees.
And since these angles are complementary, you have this equation x + 50 = 90 °
x = 90 - 50
x = 40 °
The other angle is 40 °
