Answer:

6.1

Step-by-step explanation:

Surface area of the room = 2(lw + hl + hw)

Where,

l = length = 7 m

w = width = 4 m

h = height = 3 m

Surface area of the room = 2(lw + hl + hw)

= 2(7*4 + 3*7 + 3*4)

= 2(28 + 21 + 12)

= 2(61)

= 122 m²

A 4-L can of paint covers 40 m²

Number of 4-L can of paint needed for 1 coat = 122 m² / 40 m²

= 3.05 4-L can of paint

The walls need 2 coats of paint

Number of 4-L can of paint needed for 2 coats = Number of 4-L can of paint needed for 1 coat × 2

= 3.05 × 2

= 6.1 4-L can of paint

Answer:

there are eight lateral faces in prism

There are three lateral faces for a triangular prism.

An edge is a line segment formed by the intersection of two adjacent faces. A vertex is the point of intersection of three edges.

Answer:

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).

Answer:

Aisha has 24 2p coins and 24 1p coins, then she has in total:

2p*(24) + 1*p*(24) = 48p + 24p = 72p

Step-by-step explanation:

Suppose that we have a set of N elements in a bag (if the bag is closed and we put our hand inside to grab one element, we could not distinguish them apart), and K of these elements have a given property (for example, these are red).

The probability of selecting at random one of these red elements is equal to the quotient between the number of elements with that property (K) and the total number of elements in the bag (N)

P = K/N

Now let's go to our problem.

We have 24 1p coins.

We have X 2p coins.

Then the total number of coins is: (24 + X)

We know that the probability of choosing at random a 2p coin is then:

P = X/(24 + X)

And we know that this is equal to 1/2

Then:

X/(24 + X) = 1/2

X = (1/2)*(24 + X) = 24/2 + X/2

X = 12 + X/2

X - X/2 = 12

X/2 = 12

X = 2*12 = 24

Then Aisha has 24 2p coins.

Aisha has 24 2p coins and 24 1p coins, then she has in total:

2p*(24) + 1*p*(24) = 48p + 24p = 72p

Answer:

y = -3

Step-by-step explanation:

4x – 3y = 17

x = 2

4(2) - 3y = 17

8 - 3y = 17

-3y = 9

y = -3

Answer:

y= -3

Step-by-step explanation:

if x =2, substitute

4(2) - 3y = 17

8-3y = 17

(add 3y to both sides)

8= 17 + 3y

(subtract 17 from both sides)

8-17=3y

-9= 3y

(divide both sides by 3)

-9/3=y

y= -3

Answer:

its D because they all match the sides

Step-by-step explanation:

We can graph this line using the equation given to us. The equation is in slope-intercept form, [tex]y=mx+b[/tex]. In this form, [tex]m[/tex] = slope and [tex]b[/tex] = the y-intercept.

So, we can tell that the slope is -[tex]\frac{1}{5}[/tex] and the y-intercept is (2,0).

We begin by plotting on the graph the y-intercept, (2,0).

The slope also equals the [tex]\frac{rise}{run}[/tex]. The slope is negative, so the line will slope down. From the point we have plotted, we will rise negative 1 unit. This means to move down 1 unit. From this point, we will run 5 units. Because the line is negative, we will move 5 units to the left, not the right. We land on point (5,1).

Now, we will draw a line from these two points. This is the line shown in the equation.

Good luck ^^

Answer:

[tex][AB]^2[/tex]

Step-by-step explanation:

Given

Matrices A and B

Required

Represents the square of A and B

The interpretation of the question is that:

The square of the product of A and B

This can be represented as:

The square(product of A and B)

Product means *

So, we have:

The square(A * B)

The square means ^2

So, we have:

[tex][A * B]^2[/tex]

This gives:

[tex][AB]^2[/tex]

Hence, the second option is correct

Answer:

[tex] - 12288 \div {2}^{11} = - 6 \\ forth \: answer \: is \: correct[/tex]

Answer:

4th option

Step-by-step explanation:

The nth term of a geometric sequence is

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

To find a₁ use a₁₂ = - 12288 , then

a₁ [tex](2)^{11}[/tex] = - 12288 , that is

a₁ × 2048 = - 12288 ( divide both sides by 2048 )

a₁ = - 6

Then the explicit formula is

[tex]a_{n}[/tex] = - 6 . [tex]2^{n-1}[/tex]

Answer:

y = -3/4(x - 6)^2 + 3

Step-by-step explanation:

y = ax^2 + bx + c

(4, 0)

16a + 4b + c = 0     Eq. 1

(8, 0)

64a + 8b + c = 0     Eq. 2

(6, 3)

36a + 6b + c = 3      Eq. 3

We have a system of three equations in three variables.

Eq. 2 - Eq. 1

48a + 4b = 0      Eq. 4

Eq. 2 - Eq. 3

28a + 2b = -3     Eq. 5

Eq. 4 - 2 * Eq. 5

-8a = 6

a = -6/8

a = -3/4

48a + 4b = 0

48(-3/4) + 4b = 0

4b = 36

b = 9

16a + 4b + c = 0

16(-3/4) + 4(9) + c = 0

-12 + 36 + c = 0

c = -24

The equation of the parabola is

y = -3/4 x^2 + 9x - 24

y = -3/4(x^2 - 12x + 32)

y = -3/4(x^2 - 12x + 36) + (-3/4)32 - (-3/4)(36)

y = -3/4(x^2 - 12x + 36) -24 + 27

y = -3/4(x - 6)^2 + 3

Answer:

The new coordinate after translating the figure are : (- 1 , -2)

Step-by-step explanation:

By using the following a translation mapping rule for this problem:

( x,y) → (x -2, y - 5)

“Or” meaning they want both. Since they each represent 1/14 add them together. 1/14+1/14=2/14. Then simplify 2/14 to get 1/7

So, the answer the 1/7

Answer: 162

Step-by-step explanation:

Divide 6,318 divided by 39 and you get 162.

Plus why defuk she need that manny binder clip. Does she eat them

Answer:

6318 / 39 = 162 boxes.

This question does not really make sense because you ask how many boxes are needed, then say that the clips are coming in 39 boxes.

Answer:

12

Step-by-step explanation:

Median basically means middle. So when you get a set of numbers, put them in order from least to greatest. This leaves us with ( 6  8  12 * 12  12  16 ). Now, we have to find the middle number (shown by *), but because this is an even amount of numbers (no defined middle), we take the two numbers in the middle, which would be the two 12's. If these were different numbers, we would add them together and then divide by two to get the median, but that's unnecessary here. Your median will be 12!

Answer:

When finding median, first arrange the values in ascending or descending order.

Suppose I take the ascending order:

[tex]6 \: \: 8 \: \: 12 \: \: 12 \: \: 12 \: \: 16 \\ median = ( \frac{n}{2} + 1) ^{th} value \\ n = number \: of \: terms = 6 \: digits \\ = ( \frac{6}{2} + 1) {}^{th} \: value \\ = 4 {}^{th} value \\ from \: the \: values 4 {}^{th} value = 12 \\ median = 12[/tex]
