Step-by-step explanation:
we have a right-angled triangle :
the Hypotenuse (baseline opposite of the 90° angle) is the 850 ft cable from the top of the tower down to the point on the ground 360 ft away from the tower.
then the ground distance (360 ft) and the height of the tower are the 2 legs.
so, we can use Pythagoras
c² = a² + b²
with c being the Hypotenuse.
in our case
850² = 360² + height²
height² = 850² - 360² = 592,900
height = 770 ft
the tower is 770 ft tall.
Answer:
770 feet
Step-by-step explanation:
Given
Cable = 850 feet longExtends from radio tower to a point 360 feet from the base of a towerSolving
Using the Pythagorean Theorem, we can find the height(distance from base)² + (height)² = (length of cable)²height² = (850)² - (360)²height² = 722,500 - 129,600height² = 592,900height = √592,900height = 770 feetThe volume of this rectangular prism is 48,608 cubic centimeters. What is the value of b?
Answer:
b = 49 cm
Step-by-step explanation:
Volume of a rectangular prism = width × length × height
Given:
volume = 48,608 cm³width = 16 cmlength = bheight = 62 cmSubstituting the given values into the formula and solving for b:
⇒ 48608 = 16 × b × 62
⇒ 48608 = 992 b
⇒ b = 48608 ÷ 992
⇒ b = 49
Answer:
b = 49 cm
Step-by-step explanation:
Volume of a rectangular prism: length × width × height
V = L×W×H
v = 48,608 cm³l = b cmw = 16 cmh = 62 cmSubstitute the values above and solve for b:
48,608 = b × 16 × 62
48,608 = 992b
48,608/992 = 992b/992
49 = b
Final answer: 49 cm

Answer: Mean: 10.5, Median: 9 Mode: 8 Range: 7
Step-by-step explanation
mean put the numbers in order, so 8,8,8,10,14,15 the mean is adding all numbers together and dividing by the number so 8 + 8 + 8 + 10 + 14 + 15 divided by 6 is 10.5,
median is middle so 9 since theres two middle numbers u add them both and then divide by 2
mode is the most so its 8 since 8 is there 3 times
range is the highest number and lowest number and u subtract them so 15 - 8 = 7
sorry if this is long but the answers are at the top
Answer:
Below in bold.
Step-by-step explanation:
Mean = ( 8 + 10 + 8 + 14 + 8 + 15) / 6
= 10.5.
Arrange in ascending order to find the median:
8 8 8 10 14 15
Median = mean of the middle 2 numbers
= (8 + 10)/2
= 9.
Mode = most occurring number = 8.
Range = greatest - least = 15 - 8 = 7.
Instructions: find the marked angle in the triangle diagrams and explain how you figured it out.
(Image below) Also giving brainlyest to the person with a good explanation
Answer: 84 degrees
Step-by-step explanation:
this triangle is an isosceles triangle meaning two sides are of equal length ( the two sides in this case being the ones marked with the two lines // and // ) and that also means the triangle will have two equal angles (48 and 48) how do we know that? The triangle looks like this essentially: (see image below) where angle a = to angle b
a triangles angles added up always =180 degrees
Since we proved angle a is equal to angle b, we should be able to also subtract them from 180 to find angle c. 48+48=96
and simply subtract 96 from 180 to get 84 degrees.
therefore the angle is 84 degrees

In a board game, there is a 29 chance of drawing a card that gives a player a double turn. The remaining cards are single-turn cards. A player wants to run a simulation to estimate the probability of drawing two double-turn cards in a row, assuming the first card is replaced, and the deck is shuffled afterward.
Probability helps us to know the chances of an event occurring. The probability of getting a double card in a row is 0.311.
What is Probability?Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
The probability of drawing a single double turn card for the first time, therefore,
Probability = 29/52
Further, given the card is replaced and reshuffled, therefore, the probability of getting a double card again will be,
Probability = 29/52
Thus, the probability of getting a double card in a row can be written as,
Probability = (29/52)×(29/52) = 0.311
Hence, the probability of getting a double card in a row is 0.311.

Elsa is 2 years older than Bella. Emma is twice as old as Elsa. So, what will be the sum of their ages in 1 years time. And then also find out what was the summation of their ages before 5 years from now.
Answer:
Step-by-step explanation:
Let Emma's age be 2x years, then:
Elsa's age is x years, also:
Bella's age is x - 2 years.
In one years time the sum of their ages
= 2x + 1 + x + 1 + x - 2 + 1
= 4x + 1 where x = Elsa's age now.
5 years before now
Sum of their ages
= 2x -5 + x - 5 + x - 2 - 5
= 4x - 17 where x = Elsa's age now,

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 216, 36,6 Find the 8th term.
Answer:
0.001
Step-by-step explanation:
Given (or we can find) :
First term : 216
Common ratio : 36/216 = 1/6
To find 8th term :
a₈ = ar⁸⁻¹
a₈ = (216)(1/6)⁷
a₈ = 216/279936
a₈ = 6³/6⁷
a₈ = 1/6⁴
a₈ = 1/1296
a₈ = 0.000771604938
a₈ = 0.001 (nearest thousandth)
Given that l is the centroid of triangle CDE, find CH.
A. 3
B. 4
C. 8
D. 12
Answer:
D. 12.
Step-by-step explanation:
As I is the centroid G is the midpoint of CE, so
2x + 5 = 5x - 4
5+4 = 5x - 2x
3x = 9
x = 3.
x + 5 = 2/3 * CH (Properties of the centroid of a triangle).
So as x = 3
2/3 CH = 3 + 5
CH = 8 * 3/2
CH = 12.

Polynomials are closed under the operations of addition and subtraction.
Provide one addition example and one subtraction example to demonstrate.
a set is closed under certain operation if the operation performed on two elements of the set gives an element of the same set
addition,subtractio sa well as multiplication of polynomials result into another polynomial.Therefore,the set of polynomials is closed under addition,subtraction and multiplication.
division of a polynomial need not be a polynomial (sometimes it is ,but not always).Therefore,the set of polynomials is not closed under division.see the example in the box beside.
Sample Response: If you add two polynomials, the sum is always a polynomial. Example: (2x2 + 3x) + (8x2 - 4x) = 10x2 - x If you subtract two polynomials, the difference is always a polynomial. Example: (2x2 + 3x) - (8x2 - 4x) = -6x2 + 7x

Answer:
The function f(x) = sqrt(x - 2) + 3 represents a square root function that is shifted 2 units to the right and 3 units up from the parent function f(x) = sqrt(x).
The endpoint of the function occurs when the radicand (x - 2) is equal to zero, which means x = 2. So, the function has an endpoint at (2, 3).
Since the function involves a square root, the value of y cannot be negative. Therefore, the function is increasing to the right.
The correct graph that represents the function f(x) = sqrt(x - 2) + 3 is the one that shows a curve with an endpoint at (2, 3) that increases to the right.
Therefore, the answer is: The graph shows a curve with an endpoint at 2 comma 3 that increases to the right. A.

The surface areas of two similar solids are 169 m2 and 81 m2. the volume of the larger solid is 124.92 m3. which proportion correctly shows how to solve for the volume of the smaller solid, x? = = = =
By finding the scale factor, we will see that the volume of the smaller solid is 86.75 m³.
How to get the volume of the smaller solid?If the solids are similar, then there is a scale factor between the two. Then the relation between the areas is equal to the scale factor squared, and the relation between the volumes is equal to the scale factor cubed.
This means that if the areas are 169 m² and 81 m², then we can write:
169 m² = (k²)*81 m²
Solving for k, we get:
k = √(169 m²/81 m²) = 1.44
Then if the volume of the large solid is 124.92m³ we can write:
124.92m³ = k³*V
Replacing k and solving for V we get:
124.92m³ = (1.44)³*V
(124.92m³/ (1.44)³) = V = 86.75 m³
