A tower 15m high casts a shadow 30m long. A nearby telephone pole casts a shadow 16m long. Find the height of the telephone pole. Plz show ur work, thx slatttttt
Answers
Answer:
8 feet.
Step-by-step explanation:
If we know the shadow (30 ft) of a tower (15 ft), we can use use the ratio
[tex]\frac{30}{15}=\frac{16}{x}[/tex] where 'x' is the height of the telephone pole. Cross multiply, and we get the equation [tex]240=30x[/tex]. The rest of the problem is pretty straightforward, we divide both sides by 30 to find x. In the end, you will find that the height of the telephone pole is 8 feet.

What is the area of figure?
• A. 320 square centimeters
• B. 608 square centimeters
• C. 448 square centimeters
• D. 560 square centimeters
Answers
Answer:
area of trapezium=1/2 ×20(38+18)=560cm²
Answer:
C. 448
Step-by-step explanation:
Since 38-18=20, you divide by 10 to find the base of the two triangles on the side. The height of the triangle is 16 and the formula is basexheightx1/2.
10x16x0.5=80
You then multiply that by two because there are two triangles
80x2=160
You then have to find the rectangle in the center, which is 16x18=288 cm
Then we add it all up
160+288=448

Write an inequality for the sum of twice a number and 5 is at most 15. Use y as the variable.
Answers
Answer:
The answer to the problem is 5
Step-by-step explanation:
The sum of twice a number y and 5 is at most 15" can be translated mathematically into the following inequality:
2y + 5 ≤ 15 since the sum, 2y + 5, is at most 15 but could be less than 15.
To solve this inequality for n, proceed as follows:
First, subtract 5 from both sides of the inequality as you would in solving an equation:
2y + 5 - 5 ≤ 15 - 5
2y + 0 ≤ 10
2y ≤ 10
Now, to finally solve the inequality for the variable y, divide both sides of the inequality by 2 as you would in solving an equation:
(2y)/2 ≤ 10/2
(2/2)y ≤ 10/2
(1)y ≤ 5
n ≤ 5 which is all real number less than or equal to 5.
Test Values (y = -1/2, 0, 3, 5, and n = 7):
For y = -1/2:
2y + 5 ≤ 15
2(-1/2) + 5 ≤ 15
-1 + 5 ≤ 15
-4 ≤ 15 (TRUE)
For y = 0:
2y + 5 ≤ 15
2(0) + 5 ≤ 15
0 + 5 ≤ 15
5 ≤ 15 (TRUE)
For y = 3:
2y + 5 ≤ 15
2(3) + 5 ≤ 15
6 + 5 ≤ 15
11 ≤ 15 (TRUE)
For y = 5:
2y + 5 ≤ 15
2(5) + 5 ≤ 15
10 + 5 ≤ 15
15 ≤ 15 (TRUE)
For y = 7:
2y + 5 ≤ 15
2(7) + 5 ≤ 15
14 + 5 ≤ 15
19 ≤ 15 (FALSE)
Therefore, the possible values for y which will make the relevant inequality, 2n + 5 ≤ 15, a true statement are:
{y | y is a real number and y ≤ 5}

Mr. G is trying out for the football team. The coach asks all potential recruits to run the diagonal from one corner of the field to the opposite corner (i.e. run a diagonal) and back again!
Assuming the field is a perfect rectangle that is 300 feet long and 160 feet wide, how much will Mr. G have to run? Round your answer to the nearest foot.
Answers
Answer:
340 feet
Step-by-step explanation:
Well if it is a perfect rectangle we can use the Pythagorean theorem to find the diagonal, which is a^2 + b^2 = c^2. So a=300, b=160, if we square them and add them it'll be 115600, and the square root of that is 340. So the diagonal is 340.
If you need a better explanation on the Pythagorean theorem let me know in the comments.

Answer: 36.4 miles per gallon!
Step-by-step explanation: To get your answer....divide the y (miles driven) by x (gallons used). Each divided gives you the answer of 36.4 which is the constant of proportionality between the number of miles driven and the number of gallons used.
For example: 691.6 divided by 19= 36.4
1528.8 divided by 42=36.4
1638 divided by 45=36.4

Trapezium area: 1/2 x (5+12.4) x 8
Trapezium area: 1/2 x 17.4 x 8
Trapezium area: 69.6
Rectangle area: length x breadth
Rectangle area: 12.4 x 6
Rectangle area: 74.4
Area of complete figure: Area of trapezium + Area of rectangle
Area of complete figure: 69.6 + 74.4
