80% of x is equal to 100.
Find x.
The number is 125 and the equation is 0.8x = 100
Step-by-step explanation:
80% of x is equal to 100.
Write an equation that shows the relationship of 80%, x, and 100
80% = 0.8
0.8x = 100
x = 100/0.8
x = 125
The number is 125 and the equation is 0.8x = 100

A surveyor is working to determine the gradient of a hill. The surveyor knows the hill starts at an elevation of 1755 feet and peaks at an elevation of 2105 feet. The distance of the hill from the bottom to the top is 910 feet. Select the responses that represent the angle of elevation of the hill (rounded to the nearest degree) and the trigonometric functions of the angle of elevation.
a. Cosθ= 13/5
b. Cosθ= 12/13
c. Cosθ= 13/12
d. Cosθ =13/5
Answer:
cos∅ = 12 / 13
Hence; Option b) Cosθ= 12/13 is the correct answer
Step-by-step explanation:
Given the data in the question;
the height( opposite ) = 2105 ft - 1755 ft = 350 ft
the hypotenuse = 910 ft
adjacent = x
as its illustrated in the image uploaded along this answer;
using the Pythagoras theorem
910² = 350² + x²
x² = 828100 - 122500
x² = 705600
x = √705600
x = 840 ft
Now
cos∅ = adjacent / hypotenuse
cos∅ = 840 / 910
we simplify; divide through by 70
cos∅ = 12 / 13
Therefore; Option b) Cosθ= 12/13 is the correct answer

(a) Area of the rectangle for adults: 20 m²Area of the trapezoid for children: 15 m². (b) The length of the pool for adults is 5 meters.
a) The area of each zone of the pool: Let's assume the pool is divided into two zones: one zone is a rectangle for adults, and the other zone is a trapezoid for children.
Given information:
Total area of the pool = 210 m²
Length of the pool for adults (rectangular part) = 5 m
Width of the pool (common to both zones) = 4 m
Width of the trapezoid (exclusive part for children) = 1 m (30 m - 4 m = 26 m)
Area of the rectangle for adults:
Area of rectangle = Length × Width
Area of rectangle = 5 m × 4 m = 20 m²
Area of the trapezoid for children:
Area of trapezoid = 0.5 × (Sum of the bases) × Height
Area of trapezoid = 0.5 × (4 m + 26 m) × 1 m = 0.5 × 30 m × 1 m = 15 m²
So, the area of each zone of the pool is as follows:
Area of the rectangle for adults: 20 m²
Area of the trapezoid for children: 15 m²
b) The length of the pool for adults:
The length of the pool for adults is the same as the length of the rectangular part, which is 5 m.
Therefore, the length of the pool for adults is 5 meters.

I don’t understand well kinda don’t understand can someone help me with this? Or tell me the answer?
Answer:
1.902
the answer is
the thousandth place is where the x is
0.00x
next it says that with rounding its to 2.
1.9 is rounded to 2
it says that 2 is in the thousandth place.
0.002
put it all together and you have 1.902
Answer:
2.112
Step-by-step explanation:
1) The number ends in the thousandths place.
thousandths place = 3rd decimal place after the decimal point. (ex. 1.234, 4 is in the thousandths place)
2) 2 is the nearest one when rounding
Rounding rules: 5 or above goes to the next number up. Four and below goes down.
Since none of these numbers is 5 or above, we know a two has to be in the ones place (you are unable to round up without a 5 or above).
3) A 2 is in the thousandths place.
Again, thousandths place = 3rd decimal place after the decimal point.
2.112 (2 is in thousandths place)

What is the extraneous solution to the equation (sqrt 2p+1) +2sqrt p = 12
Op=-4
O p= -2
O p = 0
Op=4
Answer:
c
Step-by-step explanation:
The extraneous solution to the given equation √(2p+1) + 2√p = 1 is x = 4.
What is an extraneous solution of an equation?"An extraneous solution is a solution, such as that to an equation, that emerges from the process of solving the problem but is not a valid solution to the problem."
Given equation is:
√(2p+1) + 2√p = 1
⇒ √(2p+1) = 1 - 2√p
⇒ (√(2p+1))² = (1 - 2√p)²
⇒ (2p + 1) = 1 - 4√p + 4p
⇒ 2p + 1 - 1 - 4p = - 4√p
⇒ -2p = - 4√p
⇒ p = 2√p
⇒ p² = 4p
⇒ p² - 4p = 0
⇒ p(p - 4) = 0
⇒ p = 0, 4
Now, putting the values of 'p' in the given equation, we get:
√(2p+1) + 2√p
= √(2 × 4+1) + 2√4
= √9 + 4
= 3 + 4 (if we take the positive sign only)
= 7
Therefore, p = 4 doesn't satisfy the given equation.
Therefore, p = 4 is the extraneous solution to the equation.
