Answer:
~ x = 12 centimeters of the route on map ~
Step-by-step explanation:
Let us plan out our steps, and solve for each:
1. We can see that we have to determine the cm of the route on the map, so let us convert the 1.8 kilometers ⇒ centimeters:
1.8 km = 180,000 cm
2. Given the information, let us create a proportionality as such:
1 = 15,000 ⇒ x - centimeters of the route on the map
x 180,000
3. Now let us cross multiply, and solve through simple algebra for x:
15,000 * x = 180,000,
x = 12 centimeters of the route on map

3х + 8 = 15
2x — 8y = 10
Answers
Answer:
(x, y) = (5, 0)
Step-by-step explanation:
Maybe you're trying to solve the system ...
3x +8y = 152x -8y = 10It is convenient to add the two equations to eliminate the y-variable.
(3x +8y) +(2x -8y) = (15) +(10)
5x = 25 . . . . . . simplify
x = 5 . . . . . . . . divide by 5
Substituting into the first equation, we have ...
3(5) +8y = 15
8y = 0 . . . . . . . subtract 15
y = 0 . . . . . . . . divide by 8
The solution to the pair of equations we think you want to solve is ...
(x, y) = (5, 0)

Find two numbers for which the sum is 101 and the difference is 47
Answers
Answer:
74 and 27
Step-by-step explanation:
let x and y be the numbers
x + y =101........eqn 1
x - y = 47.......eqn 2
solve simultaneously
from equation 2, make x the subject
x= 47 + y........eqn 3
put eqn 3 into eqn 1
(47+y) + y = 101
47 + 2y = 101
2y= 101 - 47
2y=54
y= 54/2
y= 27
put y=27 into eqn 3
x = 47 + 27
x = 74
74+27=101
74–27=47

A group of students is given a 10 by 10 grid to cut into individual unit squares. The challenge is to create two squares using all of the unit squares. Their teacher states that after the two new squares are formed, one should have a side length two units greater than the other.Which equation represents x, the side length of the greater square?
Answers
Answer:
8 is the side length of the greater square. 100=x^2+(x-2)^2
Step-by-step explanation:
64+36=100
8 squared plus 6 squared equals 10 squared
8 is 2 more than 6
100=x^2 +y^2
x-y=2
100=x^2+(x-2)^2

he diameter of the circle is 18 m. Eugene incorrectly says that the circumference of the circle is about 113.04 m. What is the circumference of the circle? What mistake did Eugene make? Use 3.14 for pi.
Answers
Answer:
The circumference of the circle is [tex]C=56.55 \:m[/tex].
Eugene confused the radius with the diameter to find the circumference of the circle.
Step-by-step explanation:
The circumference of a circle is the distance around the outside of the circle.
The circumference of a circle is found using this formula:
[tex]\begin{matrix} C=\pi \cdot d\\or\\ \, C=2\pi \cdot r \end{matrix}[/tex]
From the information given the diameter of the circle is 18 m. Therefore, the circumference of the circle is
[tex]C=\pi \cdot d\\\\C=3.14 \cdot 18 \approx 56.55 \:m[/tex]
Eugene used the wrong formula to find the circumference of a circle.
[tex]C=2\cdot(3.14)\cdot 18=113.04 \:m[/tex]
He confused the radius with the diameter.
Answer:
Eugene used the wrong formula to find the circumference of a circle.
He confused the radius with the diameter.

A child is laying on the ground relaxing and looking up at a plane that is passing by. If the plane’s altitude is 33,500 feet and the child’s eyes are located 8,200 feet away from a point on the ground directly beneath the plane, what is the angle of elevation for the child’s line of sight to the plane?
Answers
Answer:
about 76.2°
Step-by-step explanation:
The geometry can be modeled by a right triangle with the given dimensions being the side opposite the angle (height = 33,500 ft) and the side adjacent to the angle (8,200 ft). The fact that you know these two sides suggests the inverse of the tangent function may be useful.
Tan = Opposite/Adjacent
tan(angle) = (33,500/8,200)
angle = arctan (335/82) ≈ 76.246°
The angle of elevation is about 76.2°.
