Answer:
Below.
Step-by-step explanation:
I cant draw you a picture but it will be one right triangle inside the other where the vertical tower will be one leg common to 2 triangles and the base of the 2 triangles will be x and x+10 metres.
Tan 30 = h/ (x + 10)
tan 45 = h/x where h is the height of the tower.
From the second equation x = h / tan45
Substituting in the first equation;
tan30 = h / (h/tan45 + 10
Tan 30 = 1/ √3 and tan 45 = 1 so
1/ 1.732 = h/ (h + 10)
0.5774 = h/(h + 10)
h = 0.5774h + 57.74
0.4226 h = 57.74
h = 136.6 m to nearest tenth.

Answer: 81
Concept:
When a number is being squared, to being put to any power, it means the number multiplies itself by the amount of times indicated by the exponent.
For example, if 3 is to the 3rd power, then it would appear to be 3 × 3 × 3.

Emma jogs 2 miles along the beach in 1/3 of an hour. If she travels at a constant rate, how far will she jog in an hour?
Answer:
6
Step-by-step explanation:
you do 2 times 3 because you 2 miles is only 1/3 and you want do get the answer for an hour so 2/3 is 6
Answer:
6 miles
Step-by-step explanation:
If emma jogs at a constant rate she will travel 6 miles in 1 hour.
1/3 of an hour times 3 equals 1 hour and the 2 miles every 1/3 times 3 will be 6

what is the solution to 6x-(3-1)=2
Answer:
x= 2/3
Step-by-step explanation:
So, uh- First you subtract the numbers
6x-(3-1)=2
6x-(2)=2
Then you multiply the numbers
6x-1 ⋅ 2= 2
6x-2=2
(Rest of the steps:)

12. Willie rented a bike from Sarawong's Bikes. It cost $18 plus $5 per hour. Il Willie paid $63 then he rented the bike for how many hours? WILL NEED WORK DONE AND WILL GIVE BRAINLIEST
Answer:
9 hoursStep-by-step explanation:
Let the number of hours is x.
Set up an equation and solve for x:
5x + 18 = 635x = 63 - 185x = 45x = 45/5x = 9Hannah has a square plat of grass in her backyard. Each side of the plot has a length of 13 feet. On one side, semicircular fountain with a radius of feet cuts into the plot of grass. She wants to put a brick border around the edge of the grass, so that it also separate the grass from the fountain. How many feet of brick will she need? Round to the nearest whole number.
A. 50
B.48
C.58
D.55
Here we just want to find the perimeter of the image below.
We will find that the correct option is D.
The perimeter will be equal to:
The perimeter of a square of side length of 13 ft, minus 5 ft (the diameter of the circle), plus half the perimeter of a circle of diameter 5ft.
Remember that for a square of side length L, the perimeter is:
P = 4×L
For a circle of diameter D, the perimeter is:
P = 3.14*D
Then the perimeter of the square of side length of 13ft is:
P = 4×13ft = 52ft
The perimeter of the half-circle of diameter 5ft will be:
P' = 3.14×5ft/2 = 7.85ft
Then, the perimeter of the whole figure is:
perimeter = 52ft - 5ft + 7.85ft = 54.85ft
Rounding to the nearest whole number, we get:
54.85ft ≈ 55ft
The correct option is D.

find the coordinates of the points of intersection of the line 2x+3y+2=0 with the curve 2xy=-1
no spam plz fast
The point of intersection of the line 2x+3y+2=0 with the curve 2xy = -1 will be (1/2, - 1) and (1/6, 1/3).
What is substitution method?To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
Given that;
The equation of lines are,
⇒ 2x + 3y + 2 = 0
⇒ 2xy = - 1
Now,
Since, The equation of lines are,
⇒ 2x + 3y + 2 = 0 ..(i)
⇒ 2xy = - 1 ..(ii)
From (ii);
⇒ 2xy = - 1
⇒ x = - 1/2y
Put above value in (i), we get;
⇒ 2 × - 1/2y + 3y + 2 = 0
⇒ - 1/y + 3y + 2 = 0
⇒ - 1 + 3y² + 2y = 0
⇒ 3y² + 2y - 1 = 0
⇒ 3y² + 3y - y - 1 = 0
⇒ 3y (y + 1) - 1 (y + 1) = 0
⇒ (3y - 1) (y + 1) = 0
⇒ y = 1/3
And, y = - 1
So, The value of x is,
⇒ x = - 1/2y
⇒ x = - 1/2 × - 1
⇒ x = 1/2
And, x = - 1/2 × 1/3
⇒ x = 1/6
Thus, The intersection point on the lines = (1/2, - 1) and (1/6, 1/3)

4z - 15 = 4z + 11
How do you solve this?
Answer:
no solutions
Step-by-step explanation:
4z - 15 = 4z+11
Subtract 4z from each side
4z-15-4z = 4z+11-4z
-15 = 11
This is not a true statement so there are no solutions
Answer:
No solutions.
Step-by-step explanation:
4z-15=4z+11 Subtract 4z from both sides.
-4z -4z
-15=11 This statement is not true; therefore, there are no solutions.
