Answers
Answer:
1. We already have the measure of the hypotenuse and one out of two acute angle, therefore:
sin53° = x/45 => x = sin53° · 45 ≈35.94
2. We already have one out of two legs of the triangle and one acute angle so we know that:
tan27° = 48/x => x = 48/tan27° ≈ 94.21
The value of x in the first right angle triangle is 27.08.
The value of x in the second right angle triangle is 24.46.
What is the value of x?In order to determine the value of x in the first triangle, cos would be used.
Cos 53 = opposite / hypotenuse
Cos 53 = x / 45
0.7071 = x /45
x = 45 x 0.6018
x = 27.08
In order to determine the value of x in the second triangle, tan would be used.
Tan 27 = opposite / adjacent
Tan 27 = x / 48
x = 0.5095 x 48
x = 24.46

A coin is tossed 140 times. The probability of getting tails is p = 0.500. Would a result of 55 heads out of the 140 trials be considered usual or unusual? Why?
Answers
Answer:
Unusual, because the result is less than the minimum usual value
Step-by-step explanation:
A result of 55 heads out of the 140 trials is to be considered unusual .
Why is this result unusual ?In a fair coin toss, the probability of getting heads (H) or tails (T) is each 0.5 (50%) because there are two equally likely outcomes. Therefore, if you were to toss a fair coin 140 times, you would expect to get heads approximately half the time, which is 140 * 0.5 = 70 times.
Consider the result of 55 heads. This result is less than the expected value of 70 heads for 140 tosses. It is slightly below what you would anticipate for a fair coin.
So this result would be unusual.

In the spinner below, what is the probability of landing on 3?
A. 1/4
B. 1/3
C. 1/8
D. 1/6
Answers
A. 1/4 because numbers 6 and 3 have 2 bigger of a chance than the other numbers, so the spinner is out of 8. Since 3 has double the chance of being landed on than 1,2,4, and 5, than the probability of the spinner landing on the number 3 is 2/8, which is simplified to 1/4
Without specific details about the spinner, it's impossible to accurately determine the probability of landing on 3. Assuming a hypothetical spinner with numbers 1-8, the answer would be C. 1/8.
Explanation:The subject of your question is probability, which is a branch of Mathematics. The probability of an event is calculated by dividing the number of ways an event can occur by the total number of possible outcomes. Given your question, if we are to find the probability of landing on 3, we need to know how many '3's there are on the spinner, and how many total outcomes there are. Unfortunately, without a provided image or additional details about the spinner, it's impossible to accurately determine the probability.
Assuming a standard spinner with one '3' and eight total outcomes (numbers 1 through 8), the probability would be 1/8, so the answer should be C. 1/8. But again, this is based on assumptions, the actual answer could vary if the information about the spinner is different.

HELPPPPPPP Consider the equation 3/4 y = 2.4x. Solve the equation for y. What is the constant of proportionality?
Answers
1.8y is the answer because first you do 3/4y into a decimals number and then it’s 0.75 then I times it by 2.4 which is 1.8y
To solve the equation 3/4 y = 2.4x for y, we multiply both sides of the equation by 4/3 to eliminate the fraction. Simplifying the equation gives us y = 3.2x. The constant of proportionality in this equation is 3.2.
Explanation:To solve the equation 3/4 y = 2.4x for y, we need to isolate y on one side of the equation. First, we can multiply both sides of the equation by 4/3 to eliminate the fraction:
3/4 * y = 2.4x
y = (2.4x)/(3/4)
Next, we can simplify the equation by multiplying the numerator and denominator of the fraction by the reciprocal of 3/4, which is 4/3:
y = (2.4x) * (4/3)
y = (9.6x)/3
y = 3.2x
Therefore, the equation 3/4 y = 2.4x can be solved for y to give the expression y = 3.2x. The constant of proportionality in this equation is 3.2, which indicates that y is directly proportional to x with a scale factor of 3.2.

Which of the following is equal to sqrt. (50(a^6) (b^7))
Answers
Answer:
5 · a³ · b³ · √5b
Step-by-step explanation:
Start with √(50a^6b^7). Rewrite 50 as the product of the largest possible perfect square and a multiplier: 50 = 25 · 2. Then √50 = 5√2.
a^6 is already a perfect square, so find its square root: √a^6 = a^3.
b^7 = b · b^6, so √b^7 = b^3√b
Now rewrite (50(a^6) (b^7)) as √(50a^6b^7).
Then rewrite √(50a^6b^7) as 5√2 · a³ · b³ · √b.
This latter result can be simplified to 5 · a³ · b³ · √5b

What are the domain and range of the piecewise function below? HELP ASAP

The domain is the set of all point where you can evaluate the function.
As you can see, the first piece is defined from -infinity to 2 (included).
The second piece is defined from 2 to 6 (excluded).
The third piece is defined from 6 (excluded) to +infinity.
So, the domain of the function is composed by all the real numbers which are not 6:
[tex](-\infty,6)\cup(6,\infty) = \mathbb{R}\setminus\{6\} = \{x \in \mathbb{R}\ :\ x\neq 6\}[/tex]
As for the range, it is the set of all values taken by the function. We can see that the first piece spans the y axis from 0 to infinity.
The second piece is constantly equal to 2, so it adds nothing.
The third piece spans the y axis from -2 to -infinity, so the range is
[tex](-\infty,-2)\cup[0,\infty) = \mathbb{R}\setminus [2,0) = \{x \in \mathbb{R}\ :\ x\geq 0\ \lor\ x<-2\}[/tex]

A. 4 units
B. 1 unit
C. 3⁄2 units
D. 6 units
Answers
Answer:
a
Step-by-step explanation:
When two triangles are similar, their corresponding sides are in proportion. The length of NO cannot be determined from the given information.
Explanation:When two triangles are similar, their corresponding sides are in proportion. In this case, the scale factor is 3/2, meaning that the corresponding sides of triangle ABC and triangle MNO are in the ratio of 3:2.
To find the length of side NO, we can set up the proportion:
AB/MN = BC/NO = AC/OO
Since we know that AB = 3 and MN = 2, we can solve for NO:
3/2 = BC/NO
3NO = 2BC
NO = (2/3)BC
Therefore, the length of NO is (2/3) times the length of BC.
Since we don't know the length of BC, we cannot determine the exact length of NO. The answer choices provided do not match the information given, so none of the given options can be correct.

B. s>22
C. s+<43 with the line under
D. s-g<45 with the line under
Answers
Answer:Options 'A' and 'C' are correct.
Step-by-step explanation:
Let the number of sheep be 's'.
Let the number of goats be 'g'.
According to question, we have given that
the number of sheep and goats are not more than 43.
The number of goats are fewer than 22.
So, the inequalities would be
[tex]g<22\\\\and\\\\s+g<43[/tex]
Hence, Options 'A' and 'C' are correct.
The two inequalities for Harold's sheep and goats situation are A. g < 22 and C. s + g ≤ 43.
To represent the situation described about Harold's sheep and goats, we need to set up two inequalities based on the given information:
A. g < 22: This inequality indicates that the number of goats (g) is fewer than 22.C. s + g ≤ 43: This inequality means that the total number of sheep and goats combined (s + g) is at most 43.Using these inequalities, we can help Harold determine how to distribute his sheep and goats in the new field.

The height of the prism is [tex]1\frac{1}{6}[/tex] units ⇒ answer a

- The volume of a rectangular prism is
→ V = Area of the base × its height
- The volume of the rectangular prism is [tex]3\frac{25}{36}[/tex] units³
- The area of its base is [tex]3\frac{1}{6}[/tex] units²
- Substitute the values of the volume and area of the base in the rule
∴ [tex]3\frac{25}{36}=3\frac{1}{6}*h[/tex]
- Divide the two sides by [tex]3\frac{1}{6}[/tex]
∴ [tex]h=\frac{7}{6}=1\frac{1}{6}[/tex] units
* The height of the prism is [tex]1\frac{1}{6}[/tex] units
- The volume of each cubic block is [tex]\frac{1}{36}[/tex] units³
- The number of blocks = volume of the prism ÷ volume of the block
∵ The volume of the prism is [tex]3\frac{25}{36}[/tex] units³

∴ The number of blocks = [tex]3\frac{25}{36}[/tex] ÷ [tex]\frac{1}{36}=133[/tex]
