1. $0.20
2. $1.25
3. $4.00
4. $5.00​

Answer:

498

Step-by-step explanation:

For the blue block: 4(7x2) + 2(2x2) = 56 + 8 = 64

For green block: 4(12x7) + 2(7x7) = 336 +98 = 434

434 + 64 = 498

Answer:

4 x n= y²

You have to find the product of a number and 4

Answer:

√4×n

Step-by-step explanation:

4*n squared so n stands for number

[tex]\sf11 {x}^{2} - 3 {x}^{2} \\ [/tex]

They are like terms so you can just easily subtract them directly.

[tex]\sf11 {x}^{2} - 3 {x}^{2} \\ = \boxed{\bf8x {}^{2}} [/tex]

Hope it helps.

Answer:

[tex]916.11\:ft^{3}[/tex]

Step-by-step explanation:

Volume of the hexagonal pyramid =  [tex]1/3\times (area\: of \: hexagonal\:base)\times height[/tex]

Here sides of hexagonal base = 9 ft

So, Area of hexagon = [tex]6\times \frac{\sqrt{3} }{4} a^{2}[/tex]

[tex]6\times \frac{\sqrt{3} }{4} \times 9 \times 9[/tex]

[tex]= 210.5[/tex]

Height is given, 13 ft

So, volume = [tex]1/3\times 210.5\times 13[/tex]

[tex]= 916.11\: ft^{3}[/tex]

Answer:

6.08

Explainion: is shown in picture above

Step-by-step explanation:

from the second:

A=[3 -1]. -2B

[-5 0]

input this into 1

2([3 -1]) -(2B) -B =[1 3]

([-5 0]). [0 5]

[6 -2] -4B-B=[1 3]

[-10 0]. [0 5]

-5B=[1 3] -[3 -1]

[0 5]. [-5 0]

-5B= [1-3 3+1]

[0+5 5+0]

B= [-2/5 4/5]

[1 1]

A=[(19/5) (3/5)]

[-3. 2]

using the formula I derived

that's how I got A

Step-by-step explanation:

Hi there!

From the given Question, we have;

Diameter (d) = 34ft

Height (h) = 16ft

Now;

Radius (r) = d/2

= 34/2

= 17 ft

Now;

Volume (v) = 1/3(πr²h)

= 1/3(3.14 * 17² * 16) ft³

= 4839.78 ft³

Therefore, the Volume is 4839.78 ft³.

Answer:

SA = 37.5 units^2

Step-by-step explanation:

2 1/2 = 2.5

the Surface Area of the cube

SA = 6a^2

SA = 6(2.5)^2

SA = 6(6.25)

SA = 37.5 units^2

Answer:

The correct choice is option C. 4xy√3y

Step-by-step explanation:

√12x^2y^3 + 2xy√3y

√12x^2y^3 = 2√3 xy√y

2xy√3y = 2√3 xy√y

2√3 xy√y +  2√3 xy√y

= 4√3 xy√y

= 4xy√3y

Answer:

x=24

Step-by-step explanation:

3/4(x-8)=12

Multiply each side by 4/3

4/3*3/4(x-8)=12*4/3

x-8 = 16

Add 8 to each side

x-8+8 = 16+8

x=24

Answer:

x = 24

Step-by-step explanation:

Essentially, you need to break this apart.

You need to isolate the x to figure it out with division or something.

To isolate, you need to get rid of the numbers around it.

To get rid of the 3/4, you can convert it to a decimal to make it easier, and then divide both sides by 0.75 to get rid of it on the x's side.

You now have

x-8 = 12/0.75

You can quickly punch the right side into a calculator to make it easier.

x - 8 = 16

You then add 8 to both sides to finish off the x, to get

x = 24

Answer:

25 = 141 + 159/2

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

A and B are examples of direct variations because there is a nonzero constant k in each such that y=kx. A's k=1/12 while B's k=12.

D is not a direct or inverse variation because of the plus/minus constant.

C is an inverse variation because it has form y=k/x where k is nonzero. This k=12.

Answer:

C

Step-by-step explanation:

The equation representing inverse variation is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation

The only equation that fits this description is

y = [tex]\frac{12}{x}[/tex] → C

Answer:

$2.3

Step-by-step explanation:

Let the price of the orange juice be x

We know he bought 2 bottles of orange juice = 2x

He also bought an apple juice which is 0.35$ less than orange juice, so the price of the apple juice would be = (x-0.35)

The sum of these two purchases = $6.55

2x + (x-0.35) = 6.55

2x + x - 0.35 = 6.55

3x = 6.55 + 0.35

3x = 6.9

x = 6.9/3

x = 2.3

So the bottle of orange juice costs $2.3

We want to compute the probability P(A or B) because we could either solve it following path A, path B, or doing both paths.

P(A) = 1/3

P(B) = 2/5

P(A and B) = P(A)*P(B)  assuming A,B are independent

P(A and B) = (1/3)*(2/5)

P(A and B) = 2/15

--------

P(A or B) = P(A) + P(B) - P(A and B)

P(A or B) = 1/3 + 2/5 - 2/15

P(A or B) = 5/15 + 6/15 - 2/15

P(A or B) = (5 + 6 - 2)/15

P(A or B) = 9/15

We could reduce this to 3/5, but it appears your teacher has chosen not to.

Answer:

There are 0.454 kg in one pound.

So, in 120 pounds there are 0.454 x 120 kgs.

This is equal to 54.48, and the answer is 54.48 kg.

Answer:

30

Step-by-step explanation:

So we begin by assigning variables to each side with:

DE = x

EF = y

DF = z

Now we start listing a system of equations from what is given:

x+y+z=81

x=2y

x-4=z

Once we solve that with substitution, we get the result of:

x=34

y=17

z=30.

Since z is the length of DF, the length of DF is 30.

I hope this helped! :D

Answer:

x = 1 and y =5

Step-by-step explanation:

[tex]8x -2y= -2\\Divide by -2\\-4x+y = 1\\add 4x\\y= 1+4x\\[/tex]

Substitute this value of y in the next equation.

[tex]9x+5(1+4x) = 34\\9x+5+20x=34\\29x+5=34\\29x=29\\x=1[/tex]

Solve for y using x.

[tex]y=4x+1\\y=4(1)+1\\y=5[/tex]

Answer:

y is -1

Step-by-step explanation:

[tex]4x + 2y = 14 - - - (a) \\ x - 2y = 6 - - - (b)[/tex]

(a) + (b):

[tex]5x = 20 \\ x = 4[/tex]

therefore:

[tex]x - 2y = 6 \\ 4 - 2y = 6 \\ 2y = - 2 \\ y = - 1[/tex]

Answer:

y must be -1

Step-by-step explanation:

We are given the system of linear equations

4x + 2y = 14

 x - 2y = 6

and need to find the value of y.  Combining the two equations yields

5x = 20, and so we know that x must be 4.

If x is 4, then the second equation becomes 4 - 2y = 6, or -2y = 2.

Then y must be -1.

Answer:

The cost written as a fraction is​ --> 4 13/99

Step-by-step explanation:

Let x = 4.131313

100x = 413.1313

So, 100x - x = 99x

      100(4.131313) - 4.131313 = 408.99, or 409 when rounded

x = 409/99

x = 4 13/99

Answer:

D (7a-3)/4

Step-by-step explanation:

7a – 4b = 3

Subtract 7a from each side

7a-7a – 4b = 3-7a

-4b = 3 -7a

Divide by -4

-4b/-4 = (3-7a)/-4

b = (7a-3)/4

Answer:

b = (7a - 3)/4

Step-by-step explanation:

7a - 4b = 3

=> -4b = 3 - 7a

=> b = (3 - 7a)/(-4)

=> b = -(3 - 7a)/4

=> b = (-3 + 7a)/4

=> b = (7a - 3)/4
