The leteras Surface area of a cube is 324cm3
find the value and its total surface area​

Answer:

1) 6a - 2b

2) 2a + b

3) 2b + a

4) 4b - a

5) 3(a + b)

Step-by-step explanation:

2a + b ==> 2(3) + 5 = 6 + 5 = 11

2b + a ==> 2(5) + 3 = 10 + 3 = 13

3(a + b) ==> 3(3 + 5) = 3(8) = 24

4b - a ==> 4(5) - 3 = 20 - 3 = 17

6a - 2b ==> 6(3) - 2(5) = 18 - 10 = 8

Now order them from least to greatest

6a - 2b ==> 6(3) - 2(5) = 18 - 10 = 8

2a + b ==> 2(3) + 5 = 6 + 5 = 11

2b + a ==> 2(5) + 3 = 10 + 3 = 13

4b - a ==> 4(5) - 3 = 20 - 3 = 17

3(a + b) ==> 3(3 + 5) = 3(8) = 24

Step-by-step explanation:

find the area of the semi circle

[tex] \frac{\pi \times 5}{2} = {7.85cm}^{2} [/tex]

find area of the whole shape

[tex]5 \times 6 = {30cm}^{2} [/tex]

then subtract both areas to get shaded area

[tex]30 - 7.85 = 22.15[/tex]

Answer:

Carter scored 21 points

Step-by-step explanation:

If Denise scored 3 fewer points, then you would add three to 18 to get the number of points that Carter scored.

18 + 3 = 21

Question:

Find the gradient of the line passing through (6,8) and (4,10).

Answer:

-1 is the right answer.

Step-by-step explanation:

Slope of the line = The gradient of the line

Gradient of the line is known as change in the value of y-axis by change in the value of x-axis

Gradient = ∆y\∆x

[tex] Gradient = \frac{y_ 2 - y_1}{x_2 - x_1} = \frac{(10 - 8)}{(4 - 6)} = \frac{(2)}{(- 2)} =\boxed{- 1}\\[/tex]

Answer:

5a - 8b

Step-by-step explanation:

Mr Davis buys 5 package of a glue stick

= 5a

Mr. Wilson buys 8 packages of b glue sticks

= 8b

Therefore the difference in the total is

5a-8b

Step-by-step explanation:

Answer and Step-by-step explanation:

We are told that there is 24 cupcakes, which total up to be 36 dollars.

c will represent One cupcake.

We would do 36 divided by 24 to find the cost of One cupcake.

[tex]\frac{36}{24} = \frac{3}{2} = 1.5[/tex]

Each cupcake (c) is equal to $1.5.

Equations that would get us to this would be:

36/24 = c

36 = 24c

Answer:

[tex]-12*10^9[/tex]

Step-by-step explanation:

[tex](-3*10^3)*(4*10^6)[/tex]

Open up the parentheses

[tex]=-3*10^3*4*10^6[/tex]

Multiply -3 and 4

[tex]=-3*4*10^3*10^6\\=-12*10^3*10^6[/tex]

When multiplying two powers with the same base (10), add the exponents

[tex]= -12*10^(^3^+^6^)\\= -12*10^9[/tex]

I hope this helps!

Answer:

24 kilometers

Step-by-step explanation:

Given

Represent the distance with x

[tex]x = 2km\ 400m[/tex]

Required

The distance covered for 5 days (i.e. Monday to Friday)

First, we calculate the distance covered in a day

He covers the same distance when going to school and when coming back from school.

So, the daily distance is:

[tex]Daily = 2 * x[/tex]

[tex]Daily = 2 * (2km\ 400m)[/tex]

[tex]Daily = 4km\ 800m[/tex]

In 5 days, he covers:

[tex]5\ days = 5 * Daily[/tex]

[tex]5\ days = 5 * (4km\ 800m)[/tex]

[tex]5\ days = 5 * (4km+ 800m)[/tex]

Open bracket

[tex]5\ days = 5 * 4km+ 5 * 800m[/tex]

[tex]5\ days = 20km+ 4000m[/tex]

Convert m to km

[tex]5\ days = 20km+ 4km[/tex]

[tex]5\ days = 24km[/tex]

Answer:

B

Step-by-step explanation:

Its at most $8000 so the line is going to point to the left. If it was the least then the line points to the right. So we can rule out D and A. Its at most $8000 so it could be $8000 leaving the answer to be B. In the answer choice C its below $8000 but not excally $8000

Simplify

[tex](5x^{3} -7x^{2} +3x-4)-(8x ^ { 3 } +2x ^ { 2 } +3x-7) }[/tex]

Open brackets

[tex]5x^{3} -7x^{2} +3x-4-8x^3 -2x^2 -3x+7[/tex]

Collect Like Terms

[tex]-8x^3+5x^{3} -7x^{2} -2x^2+3x -3x-4+7[/tex]

Internal angles sum: 180(sides-2) = 180

5x = 180 - (48 + 90 + 17)

x = 25/5

x = 5

answer: 5

proof:

(90 + 48) + (5(5)+17) = 180

Answer:

x=5

Step-by-step explanation:

We know that a triangle consists of 180°. So to start, you take the two given angles and add them together. 48+90=138.

Now you subtract the 138 from the total of 180 to get the degrees of the remaining angle. 180-138=42°.

Now set the unknown angle equal to 42. (5x+17) = 42

Subtract 17from both sides to get 5x=25

Divide 5 from both sides to get x=5

Answer:

Step-by-step explanation:

The area of a triangle is

A=bh/2 where b is the base and h is the height, in this case

A=7(18)/2

A=63 ft^2
