Answer:
The building is 86.6 m tall.
Step-by-step explanation:
Coh Cah Toa
Coh: sin(theta) = Opp/Hyp
Cah: cos(theta) = Adj/Hyp
Toa: tan(theta) = Opp/Adj
Using Toa.
tan(theta) = Opp/Adj
tan(60°) = x/50
x = 50 * tan(60°)
x = 50 * √(3)
x ≈ 86.60254038
x = 86.6 m

Step-by-step explanation:
The table represents the metric volume measure of a liter. Each amount is represented by its power of 10.
A 2-column table with 5 rows. Column 1 is labeled Unit with entries centiliter, liter, hectoliter, kiloliter, megaliter. Column 2 is labeled Power of 10 with entries 10 Superscript negative 2, 10 Superscript 0, 10 squared, 10 cubed, 10 Superscript 6.
Complete the work to determine how many times larger a megaliter is than a hectoliter.
1. Divide powers:
106
102
2. Expand each power:
10 • 10 • 10 • 10 • 10 • 10
10 • 10
3. Divide common factors:
10 • 10 • 10 • 10 • 10 • 10
10 • 10
4. Simplify.
A megaliter is
times larger than a hectoliter.
The megaliter is 10,000 times larger than a hectoliter
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
1 mega liter = 10⁶ Liter
1 hectoliter = 10² Liter.
Hence, a megaliter is 10,000 (10⁶/10²) times larger than a hectoliter

[tex]y=\left[\begin{array}{ccc}5&-2\\2&8\end{array}\right][/tex]

Answer:
can you re word this i dont understand
-5x-15+25x-30
Help me please
Answer:
[tex]\boxed{\sf{20x-45}}[/tex]
Step-by-step explanation:
To solve this problem, all you have to do is isolate the x from one side of the equation.
-5x-15+25x-30First, you have to combine like terms.
→ -5x+25x-15-30
Then, you subtract the numbers from left to right.
→ -15-30=-45
Rewrite the problem down.
→ -5x+25x-45
By similar, add to elements.
→ -5x+25x=20x
Rewrite the problem down.
⇒ 20x-45
Therefore, the correct answer is 20x-45.I hope this helps you! Let me know if my answer is wrong or not.
Answer:
20x - 45
Step-by-step explanation:
Start by grouping like terms ( -5x and 25x) , ( -15 and -30):
= -5x + 25x - 15 - 30
Subtract the numbers: -15 -30 = -45
= -5x + 25x - 45
Combine like terms ( 5x and 25x):
= 20x - 45

Which of the following numbers CANNOT represent the probability of an event?
A. -0.5
B. 1
C. 0
D. 0.675
The number that can not represent the probability of an event is -0.5.
Option A is the correct answer.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
The probability of an event always lies between 0 and 1 (inclusive), where 0 represents an impossible event and 1 represents a certain event.
Therefore, any number outside this range cannot represent the probability of an event.
Probabilities are always non-negative values between 0 and 1 (inclusive). The value 0 represents an impossible event, meaning that the event cannot occur.
The value 1 represents a certain event, meaning that the event will definitely occur. Any value between 0 and 1 represents the likelihood that the event will occur, where a value closer to 0 represents a low probability and a value closer to 1 represents a high probability.
Negative numbers cannot represent probabilities since probabilities are always non-negative values between 0 and 1.
Thus,
The number that can not represent the probability of an event is -0.5.

What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
1. Slope of line
= (1-11)/ (-2 +6)
= -10 / 4
= -5/2
2. Slope of line
= (-2+ 5)/ (-3+ 4)

3. slope of line
= (6-6)/ (3+1)
= 0
4. Slope of line
= (7-8)/ (2-1)

Ali had 2600 pens, he gave away 1547 pens, how many pens does he have left now?
2600 pens.
to find:the remaining pens Ali have after giving 1547 away.
solution:2600 - 1547
= 1053
so, Ali has 1053 pens with him.
Ali has 2600 pens.
to find:the amount of pens Ali has left after he gave away 1547 pens.
solution:subtract 2600 from 1547.

which statement uses words to represent 5+8×3-2
Answer:
A
Step-by-step explanation:
You should always multiply before adding or subtracting. By saying "a product of 8 and 3," it means we multiplied them together first.
You should then add and subtract in the order in which they appear. Saying "five more" before "minus 2" means we did it in the right order.
