6x = 33 x= 33/6. x= 5 3/6 = 5 1/3

2/3x=8/15= x= 8/15÷2/3 x= 8/15 x 3/2 = 24/30 = 4/5

Taisha uses the elliptical cross- trainer at the gym. Her general goal is to burn 280 calories per workout, but she varies by as

Fed [463]

Given - Taisha has a general goal is to burn the 280 calories.

she is varies by the 25 calories.

Find out the maximum and minimum of calories burn by the taisha.

To proof -

let us assume that the calories burn by the taisha be x.

as given the calories are varies by the 25 calories.

then the maximum calories equation becomes

x-25 = 280

x = 280 + 25

x = 305

the maximum calories burn by the taisha is 305 calories.

minimum calories equationbecomes

x + 25 = 280

x = 255

The minmum calories burn by the taisha is 255 calories.

Hence proved

Find the coordinates of P so that P partitions AB in the ratio 3:4 with A(-9,-9) and B(5,-2).

ivolga24 [154]

The coordinates of point P are (-3 , -6)

Step-by-step explanation:

If point (x , y) partitions line AB where A = $(x_{1},y_{1})$ and B = $(x_{2},y_{2})$

at a ratio $m_{1}:m_{2}$ from A then:

1. $x=\frac{x_{1}m_{2}+x_{2}m_{1}}{m_{1}+m_{2}}$

2. $y=\frac{y_{1}m_{2}+y_{2}m_{1}}{m_{1}+m_{2}}$

∵ P partitions AB in the ratio 3 : 4

∴ $m_{1}:m_{2}$ = 3 : 4

∵ A = (-9 , -9) and B = (5 , -2)

- Substitute the coordinates of points A and B in the rules above

∵ $x=\frac{(-9)(4)+(5)(3)}{3+4}$

∴ $x=\frac{-36+15}{7}$

∴ $x=\frac{-21}{7}$

∴ x = -3

The x-coordinate of P is -3

∵ $y=\frac{(-9)(4)+(-2)(3)}{3+4}$

∴ $y=\frac{-36+(-6)}{7}$

∴ $y=\frac{-42}{7}$

∴ y = -6

The y-coordinate of P is -6

The coordinates of point P are (-3 , -6)

Expanded form for 2.918

timurjin [86]

There's an infinite number of ways to represent 2.918 in expanded form, for example:

0.02918 * 10^2
0.002918 * 10^3
0.0002918 * 10^4
0.00002918 * 10^5

etc.
