Answer:

  b)  800 cm²

Step-by-step explanation:

The surface area of the figure is the sum of the areas of each of the 6 faces. Three of the faces are shown. Because the figure is presumed to be a cuboid, the three faces not shown are identical in area to those that are.

Each face is a rectangle. As such, its area is the product of its dimension (length and width).

The front face has dimensions 10 in by 10 in. Its area is (10 in)·(10 in) = 100 in².

The top face has dimensions 10 in by 15 in. Its area is (10 in)·(15 in) = 150 in².

The right-side face has the same dimensions as the top face. Its area is also 150 in².

The sum of the areas of the three faces you can see is ...

  100 in² +150 in² + 150 in² = 400 in²

The three faces you cannot see have the same area, so the total surface area of this figure is ...

  SA = 2(400 in²) = 800 in² . . . . matches choice B

___

The formula for this can be written a couple of different ways. One that matches what we did above is ...

  SA = 2(LW +WH +LH) . . . . where L, W, H are the length, width, and height

The formula is symmetrical with respect to L, W, and H, so it does not matter which number you assign to which letter. The only thing that matters is that the same letter always represents the same number.

The above formula requires 4 multiplications and 2 additions. It can be reduced to one that requires 3 multiplications and 2 additions by combining a couple of the terms. I like this formula because it is slightly less work.

  SA = 2(LW +H(L +W))

Answer:

The Sum of the probabilities is 2/3

The probability -1/3 is less than 0

Step-by-step explanation:

Just took the quiz

The correct statements regarding why the table does not represent a probability distribution are given by:

There are two conditions:

In this problem, we have that result 10 has a probability of -1/3, hence this is one of the reasons.

The sum of the probabilities is given by:

[tex]-\frac{1}{3} + \frac{2}{5} + \frac{1}{5} + \frac{2}{5} = -\frac{1}{3} + 1 = \frac{2}{3}[/tex]

Sum of 2/3 is different than 1, hence this is the other reason.

Answer:

Her uncle's age = 47 years

Step-by-step explanation:

Sophia = 12 years old

Her Uncle Reynald tells her that if she adds 5 to her age,

= 12 + 5

multiplies the sum by 3

= (12 + 5) × 3

and then subtracts 4 from the product

= {(12 + 5) × 3} - 4

she will find his age

{(12 + 5) × 3} - 4

= (17 × 3) - 4

= 51 - 4

= 47

Her uncle's age = 47 years

Sophia wrote:

12 + 5 × 3 − 4

Using PEMDAS

P - product

E - exponent

M - multiplication

D - division

A - addition

S - subtraction

Sophia's expression can be written as = 12+(5*3)-4

= (12 + 15) - 4

= 27 - 4

= 23

Sophia's expression is wrong

Answer:

The probability that the flight would be delayed when it is raining is 0.571

Step-by-step explanation:

Here, we want to find the probability that given that it is raining, what is the probability that the flight will be delayed

Let A be the event that flight will be delayed

P(A) = 0.15

Let B be the event that it will rain

P(B) = 0.07

P(A n B) = 0.04

Thus;

P(A|B) = P(A n B)/P(B) = 0.04/0.07 = 0.571

Answer:

Step-by-step explanation:

3x + 4y = 12

4y = -3x +12

y = (-3/4)X + 12/4

y = -[tex]\frac{3}{4}[/tex]X  + 3

Step-by-step explanation:

The general vertex form is given by

[tex]y = a {(x - h)}^{2} + k[/tex]

where (h, k) is the vertex and a is a constant. So we can write the y as

[tex]y = a {(x - 2)}^{2} + 1[/tex]

To find the value of a, substitute the point (1, -4)

-4 = a(1 - 2)^2 + 1

or a = -5

Therefore, the vertex form of the parabola is

[tex]y = - 5 {(x - 2)}^{2} + 1[/tex]

$0.42

Step-by-step explanation:

create a proportion:

13/.78 = 7/x

cross-multiply to get:

13x = 7(.78)

13x = 5.46

x = 5.46/13

x = .42

Answer:

A. 69

C. 42

Step-by-step explanation:

Angle A is similar to angle C, so that makes that angle 69. With two angles figured out, we can just use basic math to find the last.

The total of all triangle angles will always be 180 degrees. Knowing this...

180-69-69=42

Thus, the angles are 69,69, and 42

Answer:

Original price= $3,200

Step-by-step explanation:

Giving the following information:

Purchase price= $2,816

Discount rate= 12% = 0.12

To calculate the original price, we need to use the following formula:

Original price= purchase price / (1 - discount rate)

Original price= 2,816 / 0.88

Original price= $3,200

Answer:

51 notes

Step-by-step explanation:

Firstly we need to get the value of the 200 pounds in koruna

From the question, 1 pound is 25.82

200 pounds will be;

200 * 25.82

= 5,164 koruna

So to know the number of possible 100 koruna bills, we simply need to divide what we have by 100

We have this as :

5,164/100

= 51.64

So the number of notes she would be is 51 100 koruna notes
