Answer:

Angle 5 I think

Step-by-step explanation:

Angle number 5 because all of the other ones are smaller then 90 degrees and angle 1 is bigger then 90 degrees.

Step-by-step explanation:

Answer:

4.

Step-by-step explanation:

If you look at the sides of the triangle, the first one has sides that have values of 10, 18, and 11.

Look at the sides of the second triangle, the values are 40, 72, and 11.

If you look at the common factors of each of these numbers, you'll see that 4 is a common factor, and the length/value of each of the sides of the 1st triangle is multiplied by 4 to get the length/value of the sides of the 2nd triangle.

18 x 4 = 72

11 x 4 = 44

10 x 4 = 40

Therefore, the scale factor is 4.

it most be eleven hundred

Answer:

Step-by-step explanation:

m∠P + m∠Q + m∠R = 180 degree

-> m∠R = 180 - ∠P - ∠Q = 180 - 99 - 31 = 50

\(\frac{PQ}{sin(R)} =\frac{PR}{sin(Q)} =\frac{QR}{sin(P)}\)

PQ = \(\frac{QR*sin(R)}{sin(P)} = \frac{11*sin(50)}{sin(99)}\)=8.53

PR = \(\frac{QR*sin(Q)}{sin(P)} = \frac{11*sin(31)}{sin(99)}\)=5.74

Answer: in this order angle d, e, f line de, ef, fd

Answer: The Pyramid has 2 pairs of congruent faces

Step-by-step explanation:

The explanation of congruent is the face has the same shape and same size. On rectangle pyramid, the height triangle are 2 same faces and 2 same faces, so it has 2 pairs of congruent faces

Answer:

6,468

Step-by-step explanation:

7 x 7 x 11 x 4 x 3 = 6,468

Answer:

154mm²

Step-by-step explanation:

The first step is to break down all the shapes.

- 4 triangles and one parallelogram

Lets find area of the upper triangles first

Formula: 1/2(b)(h)

A = 1/2 (7)(11)

A = 38.5mm²

Since there's two of those, multiply by 2

38.5mm² x 2 = 77mm²

Now, we move to the area of the bottom triangles

Same formula: 1/2(b)(h)

A = 1/2(7)(3)

A = 10.5mm²

Again, we multiply by 2 since there are two of those

10.5mm² x 2 = 21mm²

Lastly, we find the area of the parallelogram

Formula: b x h

For the base, we double the length of the base of the triangles

7 x 2 = 14

A = 14 x 4

A = 56mm²

Now we add all of them up

77mm² + 21mm² + 56mm²

= 154mm²

Answer: I believe you should make two different graphs, one for the hares, and one for the lynx, so then you can compare them. CAUTION: Remember, they are measured in thousands and hundreds, not the same unit.

Answer: The correct answer is:

Probability of rolling a number less than 3: 2/6 or 1/3

Step-by-step explanation:

Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.

Probability of not rolling a number less than 3: 4/6 or 2/3.

Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D

Answer:

Aristocracy is a form of government in which political power is held by a select few privileged people called aristocrats or nobles. Coming from a Greek word meaning “rule by the best,” aristocrats are considered the most qualified to rule because of their moral and intellectual superiority.

Answer:

A, C

Step-by-step explanation:

If it is inversely proportional then y = k/x

Let's try one by one for the options. (im replacing y and x in the equation and finding k to see if k is the same all throughout)

A.

6 = k/1 (k=6)

3 = k/2 (k=6)

2 = k/3 (k=6)

1.5 = k/4 (k=6)

Yes! It's the same everywhere so this is correct!

B.

7.5 = k/2 (k=15)

5 = k/3 (k=15)

3 = k/5 (k=15)

2 = k/7 (k=14)

For the last one k is not the same so nope. It is wrong.

C.

24 = k/1 (k=24)

8 = k/3 (k=24)

k = 6×4 = 24

k = 24×1 = 24

This is correct too.

D.

k = 0.1×200 = 20

k = 0.3×40 = 12

k = 0.8 × 25 = 20

We can already see that k is not the same everywhere.

Only A and C, x and y are inversely proportional for all of the values

Answer: 2/5 + 1/10

the probability of the spinner landing in 1 or 4 is 5/10 = 1/2.

2/5 + 1/10 = 1/2.

The smallest number is the one closest to zero, or after zero, if it's a negative number, while the largest number is the number with the largest difference from the smallest, or the highest of value (not considering all situations). Usually, you would use the ascending order method for graphing numbers based on their value, which is indeed smallest to largest. According to thefreedictionary.com, "A function or variable continuously approaching zero as a limit." Tip: In ordering numbers based on value, the whole numbers that aren't negative are considerably believed to be the easiest numbers to order.

With that being said, here is the order of the numbers from smallest to largest:

4.38

4.5

4.6

4.9

Answer:

Here are the numbers ordered from closest to zero to farthest from zero:

4.38 (closest to zero)

4.5

-4.6

-4.9 (farthest from zero)

Step-by-step explanation: 54 divided by 27 is 2 so 1 lollipop is 2 candy bars!

Answer:

Step-by-step explanation:

Answer:

As the time increases, the distance from the floor decreases by 40 cm per second. You find 40 by taking (6,1140) and (9,1020). The slope formula is y2 - y1 over x2- x1. Plug in the variables and you get (1020-1140)/(9-6)= -120/3= -40. 

Step-by-step explanation:

Answer:

You can calculate the likeliness of the spinner landing on blue or red as the  more spins you have the more accurate the results would be. In this case after 200 spins Tiffany calculated that the spinner landing on blue has a 60% chance while landing on red has a 40% chance. Therefore this might not be fair as there is a 60% chance landing on blue.

Step-by-step explanation:

Answer:

To find the first four terms of the series, we can substitute the values of n from 1 to 4 in the given formula and simplify:

n=1: -4(2/3)^0 = -4(1) = -4

n=2: -4(2/3)^1 = -4(2/3) = -8/3

n=3: -4(2/3)^2 = -4(4/9) = -16/9

n=4: -4(2/3)^3 = -4(8/27) = -32/27

So the first four terms of the series are -4, -8/3, -16/9, -32/27.

To determine if the series converges or diverges, we need to find the common ratio r, which is the ratio of any term to its preceding term:

r = (-4(2/3)^n) / (-4(2/3)^(n-1)) = 2/3

Since the absolute value of the common ratio is less than 1, the series converges.

To find the sum of the series, we can use the formula for the sum of an infinite geometric series:

S = a / (1 - r)

where a is the first term and r is the common ratio. Substituting the values we found:

S = -4 / (1 - 2/3) = -4 / (1/3) = -12

So the sum of the infinite geometric series is -12.

Answer:

a)  The first four terms of the series are:

    -4, -8/3, -16/9, -32/27

b)  The series converges.

c)  The sum of the infinite geometric series is -12.

Step-by-step explanation:

Given infinite geometric series:

\(\displaystyle \sum^{\infty}_{n=1} -4 \left(\dfrac{2}{3}\right)^{n-1}\)

Therefore, the formula for the nth term of the sequence is:

\(a_n=-4 \left(\dfrac{2}{3}\right)^{n-1}\)

where:

Calculate the first four terms of the series by substituting the n-values 1 through 4 into the nth term formula.

\(a_1 = -4 \left(\dfrac{2}{3}\right)^{1-1} = -4 \left(\dfrac{2}{3}\right)^{0}=-4\)

\(a_2 = -4 \left(\dfrac{2}{3}\right)^{2-1}= -4 \left(\dfrac{2}{3}\right)^{1}=-\dfrac{8}{3}\)

\(a_3 = -4 \left(\dfrac{2}{3}\right)^{3-1}= -4 \left(\dfrac{2}{3}\right)^{2}=-4 \left(\dfrac{4}{9}\right)=-\dfrac{16}{9}\)

\(a_4 = -4 \left(\dfrac{2}{3}\right)^{4-1}= -4 \left(\dfrac{2}{3}\right)^{3}= -4 \left(\dfrac{8}{27}\right)=-\dfrac{32}{27}\)

A geometric series converges if the absolute value of its common ratio is less than 1. As r = 2/3 and |2/3| < 1, the series converges.

Use the infinite geometric series sum formula to find sum of the infinite series.

\(\boxed{\begin{minipage}{5.5 cm}\underline{Sum of an infinite geometric series}\\\\$S_{\infty}=\dfrac{a}{1-r}$,\;\;for\;$|r| < 1$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the first term. \\ \phantom{ww}$\bullet$ $r$ is the common ratio.\\\end{minipage}}\)

Substitute a = -4 and r = 2/3 into the formula to find the sum of the infinite series:

\(\begin{aligned}\implies S_{\infty}&=\dfrac{-4}{1-\frac{2}{3}}\\\\ &=\dfrac{-4}{\frac{1}{3}}\\\\&=-4 \cdot \dfrac{3}{1}\\\\&=-\dfrac{12}{1}\\\\&=-12\end{aligned}\)

Therefore, the sum of the given infinite geometric series is -12.
