Can someone give me the answer to this question please ?

Step-by-step explanation:

just think calm and logically.

what are the parts of the surface area ?

rest assured, there is no such thing like a general equation for the surface area of a prism.

well sure, there could be, but there are so many different variations, to describe them would be more complicated than the formula. so, we only have a general approach for the volume of such regular prisms (ground area × height).

but for the surface area we just have to break this problem into smaller problems we can easily solve and then add the results together.

so,

we see, there are 5 sides of this special prism.

top, bottom, left, right and front.

so, we need to calculate these 5 areas and simply add them up.

left and right are rectangles. one is

11×18 = 198 in²,

the other is

12×18 = 216 in², together they are 414 in².

the front is a rectangle

8×18 = 144 in²

top and bottom are equal triangles. each is

8 × height / 2

or per Heron's formula

A = sqrt(s(s -a)(s - b)(s -c)) where s = (a + b + c)/2

our s here is

s = (8 + 11 + 12)/2 = 15.5

A = sqrt(15.5×7.5×4.5×3.5) = sqrt(1830.9375) =

= 42.78945548... in²

both together are 85.57891095... in²

so, the total surface area is

414 + 144 + 85.57891095... = 643.578911... in²

if we need to round to e.g. whole square inches, this would be

644 in²

Answer:

C

Step-by-step explanation:

the measure of an inscribed angle is half the measure of its intercepted arc, so

arc DE = 2 × ∠ DFE = 2 × 18° = 36°

DF is a diameter of the circle , then

arc DEF = 180° , then

arc EF = 180° - 36° = 144°

Now

mEF and m DE lies in one line hence supplementary

Answer:

4 pack

Step-by-step explanation:

£2.04 ÷ 4 is 51p. If we divide £2.04 by 4 (we are dividing it by 4 because that is the amount of rolls) it gives us how much 1 roll is in that pack. 1 roll = 51p in the 4 pack.

£4.68 ÷ 9 is 52p. If we divide £4.68 by 9 (we are dividing it by 9 because that is the amount of rolls) it gives how much 1 roll is in that pack. 1 roll = 52p.

Therefore, the 4 pack is cheaper as 1 roll costs less. The 4 pack is better value.

Answer:

can I see the table so I can see where your x and y is

Answer:

-3

Step-by-step explanation:

assuming that the x is the same in both problems, to get 2 as your solution, in the first problem x÷8 would have to equal 0. so x would have to be 0. sense 0 + 2 equals 2.

Then plug 0 into x in the first equation to check your work, and if it equals the answer givin to you (2), plug 0 into the equation you are trying to solve.

so 9×0 is 0, then 0 - 3 would give you -3

Answer:

123

Step-by-step explanation:

(2+x)/8 = 2

Multiply both sides by 8 to eliminate the fraction

2+x =16

x=14

        9x14 = 126

    126-3 = 123

Answer:

Question 1:

Perfect square trinomial

A trinomial has three terms

Question 2:

Neither

The polynomial only has one term that is being squared.

In the first reaction, Gold (Au) gets 3 electrons and became Gold. In the second reaction, Iodine (I) loses 2 electrons and became Iodine.

When the atom loses the election then it is called a cation and when it gains the electron is called an anion.

Two reactions are given.

First reaction;

Au³⁺ + 3e⁻ ⇒ Au

In the first reaction, Gold (Au) gets 3 electrons and became Gold.

Second reaction;

2I⁻ ⇒ I₂ + 2e⁻

In the second reaction, Iodine (I) loses 2 electrons and became Iodine.

So multiplying decimal and whole number means it will always equal as a decimal. But multiplying decimal with decimal means could equal whole or decimal number

Step-by-step explanation:

Answer:

Essentially, they are same thing

Step-by-step explanation:

For example, 3 x 0.4 = 1.2

0.3 x 0.4 = 0.12

The only thing that changes are the amount of numbers behind the decimal. So when multiplying decimals, you just multiply like normal (3 x 4 = 12), then you count the amount of decimal spaces (two) and you take the number (12) and move the decimal place to the left twice. 12.0 would go to 1.2 if multiplying by a tenth.

Answer:

Answer:

81

Step-by-step explanation:

63×135=8505

8505÷105=81#

In 63 pounds, there are equivalent 81 dollars.

A unit conversion expresses the same property as a different unit of measurement.

For instance, time can be expressed in minutes instead of hours, while distance can be converted from miles to kilometers, or feet, or any other measure of length.

Given is that -

1 pound = Rs.135

1 dollar = Rs. 105

Now, we can write that 1 rupee as -

Rs. 1 = 1/105 dollar

So, in 1 pound we can write -

1 pound = 135 x 1/105 dollars

63 pounds = 63 x 135 x 1/105 = 81 dollars

Therefore, in 63 pounds, there are equivalent 81 dollars.

Answer:

The Enlightenment was a seventeenth- and eighteenth-century intellectual movement that aimed to better society via fact-based reasoning and investigation. The Enlightenment introduced secular ideas to Europe, changing people's perceptions of problems like liberty, equality, and individual rights. Today, such ideas are the bedrock of the world's most powerful democracies.

Step-by-step explanation:

two ideas that emerged from the Enlightenment:

Intellectuals like Jean-Jacques Rousseau and John Locke introduced the idea that no monarch should have absolute authority. Both claimed that leaders' authority came from the people, not from God. And, according to Locke, if people disagreed with their leader, they had the right to have their government replaced with one that honored their rights.

Pre-Enlightenment Equality Powerful individuals known as the nobility had exclusive privileges to buy land, avoid taxes, and hold privileged jobs across Europe, while the lowest elements of society battled to make ends meet. The Enlightenment questioned this system, with intellectuals such as John Locke arguing that all men are created equal and that no one should be born with more power than another.
