Answer:

The correct answer is A. 600 square centimetres

Step-by-step explanation:

Let's recall that the formula of the surface area of a cube is:

A = 6s², where s  is the side length of the cube.

Replacing with the value we know, we have:

A = 6 * 10²

A = 6 * 100

A = 600 square centimetres

The correct answer is A. 600 square centimetres

Step-by-step explanation:

Hi, hope this helps!

Method 1:

Calculate this shape as a trapezium. This is a trapezium because it has one pair of parallel sides. The way to calculate the area of a trapezium is this:

- Half the sum of the parallel sides

- Multiply the perpendicular height between them

In this case, 4 and 2 are parallel, so we add them together (4 + 2 = 6) then we divide by two (6 ÷ 2 = 3). Then we multiply our answer by the perpendicular length between the two parallel sides (assuming the side on the left is at a right-angle, 3 x 2 = 6).

Method 2:

Calculate this shape as a rectangle + a triangle. If you split the shape so the pointy bit on the right becomes a triangle and the left becomes a square, you can calculate the area without knowing the formula for calculating a trapezium (see above ^).

- Area of the square / rectangle = length x width = 2 x 2 = 4

- Area of the triangle = 1/2 x length x width = 2 x 2 x 1/2 = 4 x 1/2 = 4 ÷ 2 = 2

Then we add the two areas together (4 + 2 = 6).

I hope this helped and I wasn't waffling on :)

Answer:

irrational

Step-by-step explanation:

rational - a number that can turn into a fraction (you could do this with a perfect square)

Irrational - a number that cannot be expressed as a fraction

The square root of 29 is an irrational number because it can not be expressed as a fraction.

To determine whether the square root of 29 is rational or irrational, we need to check if it can be expressed as a fraction (ratio) of two integers.

Assuming that the square root of 29 is rational, we can represent it as √29 = a/b, where a and b are integers with no common factors other than 1, and b is not equal to 0.

Squaring both sides of the equation (√29)² = (a/b², we get 29 = (a²)/(b²).

This implies that 29 is equal to the ratio of two integers (a²)/(b²), which means that 29 can be expressed as a fraction. However, this is not true because 29 is a prime number and cannot be written as a fraction of two integers.

Therefore, the square root of 29 cannot be expressed as a fraction and is therefore irrational.

Hence, the square root of 29 is an irrational number.

As given that 2x=2(10)+88

x=108/2

x=54cm

May be it's help you;)

Answer:

The length of each of the two equally long sides is 26 cm

The length of the longer side is 36 cm

Step-by-step explanation:

Let the length of each of the two equal sides be represented by x

The other side = 10 + x

Perimeter of triangle (P) = sum of all sides of the triangle

88 = x + x + 10 + x

88 = 3x + 10

3x = 88 - 10

3x = 78

x = 78/3 = 26

Length of each of the two equally long sides (x) = 26 cm

Length of the longer side = 10 + x = 10 + 26 = 36 cm

Answer:

The distance Ted will run in 285 minutes is 60 km

Step-by-step explanation:

The information in the question states as follows;

The distance Ted can run in 95 minutes = 20 km

Therefore, from the equation of speed, we have;

Speed = Distance covered ÷ Time taken

Ted speed, s = 20 km/(95 minutes) = 4/19 = 0.21 km/minute

Therefore, the distance, d Ted will cover in 285 minutes is given as follows;

d = Speed × Time = 0.21 km/minute × 285 minutes = 60 kilometres

The distance Ted will run in 285 minutes = 60 kilometres.

Answer:

285km=60

Answer:

A.) P^2 - 10p + 24 = 0

B.) 6 or 4 dollars

Step-by-step explanation:

Given that a company’s weekly revenue, in thousands, is modeled by the equation

R = -p2 + 14p,

where p is the price of the product it makes. The company is considering hiring an outside source to distribute its products, which will cost the company 4p + 24 thousand dollars per week.

If the company want to break even, the cost of hiring distributors will be equal to the revenue per week.

Therefore,

-P^2 + 14p = 4p + 24

Collect the like terms

-P^2 + 14p - 4p - 24 = 0

-P^2 + 10p - 24 = 0

Multiply all by minus sign

P^2 - 10p + 24 = 0

B.) To find P, factorize the equation above.

P^2 - 10p + 24 = 0

- 6 x - 4 = 24 and - 6 - 4 = 10

P^2 - 4p - 6p + 24 = 0

P( p - 4 ) - 6( p - 4 )

P - 6 = 0 or p - 4 = 0

P = 6 or 4

Substitute both back into the equation to test their authenticates

When p = 6

6^2 - 10(6) + 24 = 0

When p = 4

4^2 - 10(4) + 24 = 0

Answer:

(-2, 21) and (8, 8)

Step-by-step explanation:

Use the two coordinate pairs (-2, 21) and (8, 8).  As we go horizontally from the first to the second, the run (change in x) is 10 and the rise (change in y) is -13.  Thus, the slope of the line through (-2, 21) and (8, 8) is m = rise / run = -13/10.

The equation of this line follows y - k = m(x - h):

y - 8 = (-13/10)(x - 8)

[tex]\boxed{\angle RQS = 56 \ degrees}[/tex]

[tex]\boxed{\angle SRT = 56 \ degrees}[/tex]

Step-by-step explanation:

A) ∠QRS = 90 degrees (The angle of the triangle opposite to the diameter is always 90)

Given that QR = 68 degrees

So,

∠RSQ = [tex]\frac{1}{2} (QR)[/tex]

∠RSQ = 68/2

∠RSQ = 34 degrees

Now, Finding ∠RQS

∠RQS = 180-90-34

∠RQS = 56 degrees

B) ∠SRT = ∠QRS - ∠QRT

=> ∠QRS = 90 (Mentioned above) , ∠QRT = 56 (Given)

So,

∠SRT = 90-56

∠SRT = 34 degrees

Answer:

171 points.

Step-by-step explanation:

If five test scores have a mean of 90, all the scores added together will be 5 * 90 = 450.

The middle score is 91, so the other four scores added together will be 450 - 91 = 359.

The mode is higher than the median, so we can assume that the highest two numbers are the same: 94. 94 * 2 = 188. 359 - 188 = 171.

That means that the sum of the two lowest test scores is 171 points.

Hope this helps!

Answer:

The sum of the two lowest test scores is 171.

Step-by-step explanation:

We see that there are 5 test scores, so the median ( middle score ) was not taken to be the average of the two middle scores. It is an element present in the set of five test scores. The mode of course has to be present in the set, but multiple times. If we can figure out how many times this mode is present in the set, it would help us.

As 91 is the middle value, there has to be two above 91. Therefore, as 94 appears the most frequent, is must appear twice.

Now another key thing we need here is the sum of all 5 numbers. Given a mean of 90, 90 [tex]*[/tex] 5 = the sum of all 5 numbers = 450. Therefore, the sum of the two lowest test scores should be = 450 - 94 - 94 - 91 = 171 - which is our solution.

Answer:

(-1,5) and [tex](3, \frac{1}{125})[/tex] are points on the graph

Step-by-step explanation:

Given

[tex]g(x) = \frac{1}{5}^x[/tex]

Required

Determine which point in on the graph

To get which of point A to D is on the graph, we have to plug in their values in the given expression using the format; (x,g(x))

A. (-1,5)

x = -1

Substitute -1 for x in [tex]g(x) = \frac{1}{5}^x[/tex]

[tex]g(x) = \frac{1}{5}^{-1}[/tex]

Convert to index form

[tex]g(x) = 1/(\frac{1}{5})[/tex]

Change / to *

[tex]g(x) = 1*(\frac{5}{1})[/tex]

[tex]g(x) = 5[/tex]

This satisfies (-1,5)

Hence, (-1,5) is on the graph

B. (1,0)

x = 1

Substitute 1 for x

[tex]g(x) = \frac{1}{5}^x[/tex]

[tex]g(x) = \frac{1}{5}^1[/tex]

[tex]g(x) = \frac{1}{5}[/tex]

(1,0) is not on the graph because g(x) is not equal to 0

C. [tex](3, \frac{1}{125})[/tex]

x = 3

Substitute 3 for x

[tex]g(x) = \frac{1}{5}^x[/tex]

[tex]g(x) = \frac{1}{5}^3[/tex]

Apply law of indices

[tex]g(x) = \frac{1}{5} * \frac{1}{5} * \frac{1}{5}[/tex]

[tex]g(x) = \frac{1}{125}[/tex]

This satisfies [tex](3, \frac{1}{125})[/tex]

Hence, [tex](3, \frac{1}{125})[/tex] is on the graph

D.  [tex](-2, \frac{1}{25})[/tex]

x = -2

Substitute -2 for x

[tex]g(x) = \frac{1}{5}^x[/tex]

[tex]g(x) = \frac{1}{5}^{-2}[/tex]

Convert to index form

[tex]g(x) = 1/(\frac{1}{5}^2)[/tex]

[tex]g(x) = 1/(\frac{1}{5}*\frac{1}{5})[/tex]

[tex]g(x) = 1/(\frac{1}{25})[/tex]

Change / to *

[tex]g(x) = 1*(\frac{25}{1})[/tex]

[tex]g(x) = 25[/tex]

This does not satisfy  [tex](-2, \frac{1}{25})[/tex]

Hence, [tex](-2, \frac{1}{25})[/tex] is not on the graph

7² + 3(4² + 3 + 2) = 49 + 3(16 + 3 + 2)

                           = 49  + 3 * 21

                           = 49 + 63

                           = 112

Answer:

Step-by-step explanation:

Displacement vector R = 2i + j +  3k

Unit vector along displacement vector

= R / I R I

= ( 2i + j +  3k )  / √ ( 2² + 1² + 3² )

= ( 2i + j +  3k )  / √ 14

Now force F acts in the direction of this unit vector . It is magnitude of 20 N

So this vector can be represented by the following expression

F = 20 [  ( 2i + j +  3k )  / √ 14 ]

[tex]F= \frac{20}{\sqrt{14} } \times ( 2i+j+3k)[/tex]

P(t) = 12100*(1.04^t)

(b) for 2008,

P(2008-2000)

= P(8)

= 12100*(1.04^8)

= 12100 * 1.368569

= 16559.7

= 16560  (nearest integer)
