116 is 145% of what number

Answers

Answer 1

Answer: $116\ \rightarrow\ 145\%\nx\ \rightarrow\ 100\%\n\nx= (116\cdot100\%)/(145\%) \n\nx= (4\cdot29\cdot5\cdot20)/(5\cdot29) \ \ \ \Rightarrow\ \ \ x=4\cdot20=80$

Answer 2

Answer: 116 = 145% x ?
116 = 1.45 x ?
116 ÷ 1.45 = 80
? = 80

What number is represented by 3^3 x 7?

Answers

3^3=27 and 27 x 7= 189, so your answer is 189

${3}^(3) * 7 \n = 27 * 7 \n = 189$

Therefore, 3^3 ×7 represents 189.

Answer:

LM = 2(MP)

Step-by-step explanation:

The radius KN is perpendicular to LM meaning that the line is split in half at the crossing. Review properties of circles to see why this is true.

Since we know this, we can say LM = LP + MP. And LP = MP.

So we can say LM = 2(MP).

Crater Lake Oregon is a roughly circular lake. The lake basin formed about 7000 years ago when the top of a volcano exploded in an immense explosion. Hillman Peak, Garfield Peak, and Cloudcap are three mountain peaks on the rim of the lake. The peaks are located in a coordinate plane at H(-4,1), G(-2,-3), and C(5,-2). Find the coordinates of the center of the lake.

Answers

To solve the problem we must find the equation of the circumference of the form:
(Xa) ² + (Yb) ² = r²
They do not give us the center or the radio, but we have 3 points.
With the points H (-4,1), G (-2, -3) and C (5, -2) we find 3 equations
1) (-4-a) ² + (1-b) ² = r²
2) (-2-a) ² + (-3-b) ² = r ²
3) (5-a) ² + (-2-b) ² = r ²
Now we have a system of 3 equations with 3 unknowns: r, a, b
When solving the system we have to:
r = 5
a = 1
b = 1
Therefore, the center of the circumference of the lake is the point (a, b)
That is, the point (1,1)

Answer:

The coordinates of the center of the lake are $((-1)/(3),(-4)/(3))$ .

Step-by-step explanation:

It is given that Hillman Peak, Garfield Peak, and Cloudcap are three mountain peaks on the rim of the lake. The peaks are located in a coordinate plane at H(-4,1), G(-2,-3), and C(5,-2).

If we joint these points, then we get a triangle and the center of a triangle is known as centroid.

The formula for centroid of a triangle is

$Centroid=((x_1+x_2+x_3)/(3),(y_1+y_2+y_3)/(3))$

The centroid of the triangle H(-4,1), G(-2,-3), and C(5,-2) is

$Centroid=((-4-2+5)/(3),(1-3-2)/(3))$

$Centroid=((-1)/(3),(-4)/(3))$

Therefore the coordinates of the center of the lake are $((-1)/(3),(-4)/(3))$ .
