Answer:

The first five terms in Pattern B are 3, 7, 11, 15, 19.

Step-by-step explanation:

Answer:

-5

Step-by-step explanation:

Recall that slope = rise/run.

Here the change in y (the rise) is -10 (y changes from +12 to +2), and the  change in x (the run) is 2, since x increases from 3 to 5).

The slope of the line through these points is m = rise / run = -10/2 = -5

Answer: 1,2,and 4. I did it online and got it right!

Answer:

B. 15 square meters (for the triangles)

D. 25 square meters (for the square base)

Bonus: The total surface area would be 85 square meters.

Step-by-step explanation:

The square base is easier to deduce here; simply square 5 to get 25 square meters for the base.

The triangles require some math, however. But it is relatively simple

(5 * 6)/2

30/2

15 square meters for the triangles.

For bonus, I'll find the total surface area.

5² + 4((5 * 6)/2)

First, square 5 to get 25.

25 + 4((5 * 6)/2)

Now multiply 5 * 6 to get 30.

25 + 4(30/2)

Then divide 30 by 2 to get 15.

25 + 4(15)

Now multiply 4 by 15 to get 60.

25 + 60

Lastly, add 25 and 60 to get 85.

The entire square pyramid's surface area is 85 square meters.

Answer: 1300 cm^3, 850 cm^2

Step-by-step explanation:

With a triangular prism, you need to calculate the surface area of the triangle first and then the length. Here's how to solve for the volume (A):

Triangles is b*h/2, plug in the equation

10*13/2

130/2

65

Now use the length of the rest of the shape, which is 20 cm.

65*20=1300

the volume is 1300 cm^3.

for B, finding the surface area requires you to analyze each individual part of the shape.

Each part colored in represents a different shape:

Red:

10*20=200

Blue:

13*10/2=65

65*2=130 (Two triangles)

Green:

13*20=260

260*2=520 (Two rectangles)

Add them all up together.

200+130+520= 850 cm^2

Answer:

She can type 180 letters in a minute and a half.

Step-by-step explanation:

6 letters per 3 seconds, so we need to find how many letters per 90 seconds, or minute and a half.

6/3 = x/90

Where x represents how many letters she can type in 90 seconds.

2 = x/90

Multiply by 90.

x = 180.

Answer:

y = 6z - 5

Step-by-step explanation:

Start with the given function y = 2x -5.  Substitute the given 3z for x:

y = 2(3z) -5

Simplify this through multiplication:

y = 6z - 5

The answer is: a

Each term in the second sequence is 10 times the corresponding term in the first sequence.

A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.

The nth term of a GP is aₙ = arⁿ⁻¹

The general form of a GP is a, ar, ar2, ar3 and so on

Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )

Given data ,

Let the first sequence be represented as A

Now , the value of A = { 1 , 2 , 3 , 4 , 5 }

Let the second sequence be represented as B

Now , the value of B = { 10 , 20 , 30 , 40 , 50 }

And , a₂ / a₁ = 20 / 10 = 10

So , the common ratio of GP = 10

So , the ratio of the first term of the second sequence and first term of first sequence is 10

Hence , the second sequence's terms are 10 times longer than their equivalents in the first

Answer:

7623000

Step-by-step explanation:

Answer:

1. I need to see the table to answer that

2. I think you need to find the probability of getting 1, H. That probability is 1/10 which is also 10%.

3. can't answer a, but b is 1/14 or 7%

4. as a fraction= 1/6

as a percent= 17% (rounded up)

Step-by-step explanation:

2. I just took the outcome needed and decided by the possible outcomes.

3. That was a compound event so I just got the probability of flipping tails (1/2) and multiplied it by the probability of getting a white ball (1/7)

4. another compound event, I got the probability of getting a medium (1/3) and multiplied it by getting yellow (1/2)

Answer:

The height is 10.

Step-by-step explanation:

Since the trapezoid is 2 triangles plus a square, we can split it into a rectangle (the two triangles put together) and the square. Let's call the height "x". The trapezoid's area becomes 8x [the square]+2x[the traiangle]. But wait! It states that the area is 70m, so the expression becomes the equation 10x=70m, which is x=10. Therefore, the height is 10.
