New amount = starting value x (1- percent)

New amount = 250 x (1-0.34)

New amount = 250 x 0.66

New amount = 165

Answer:

PIC 1: Option 2. this relation is a function

PIC 2. Option 1. this relation is not a function

Step-by-step explanation:

To be a function, the domain (x value) can only have one range (y value). But one range can have multiple domain

PIC 1

Function {(-2, -4) (-1, -4) (3, -4) (6, -4)}

This relation is a function

EXPLANATION: each domain only have one range

PIC 2

Function {(-4, -2) (-4, -1) (-4, 3) (-4, 6)}

This relation is not a function

EXPLANATION: each domain has multiple range.

Hope this helps!! :)

A 4000 kg truck is parked on a 7.0° slope. How big is the friction force on the truck?

Lelu [443]

Answer:

4777.28 N

Step-by-step explanation:

The gravitational force down the slope is given by the formula;

(mass *g * sin θ )

where;

θ is the angle of inclination of the slope

g is the gravitational pull

We plug in the given values into the above expression;

(4,000 x 9.8 x sin 7) = 4777.28 N.

The frictional force must equal to 4777.28 N (pointing up the slope).

What is the formula for a triangle prism

vekshin1

Answer:

Remember the formula for calculating volume is: Volume = Area by height. V = A X h.

For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.

So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h.

Step-by-step explanation:

What angle do the minute and hour hands make at 4:30??

seraphim [82]

Answer:

45°

Step-by-step explanation:

The hour hand makes a trip of 360° around the face of the clock in 12 hours, so in 4.5 hours will make an angle of ...

... (4.5/12)·360° = 135°

clockwise from straight up.

The minute hand makes that 360° turn in 1 hour, so in 30 minutes, it will be 180° clockwise from straight up.

The difference between the angles of the hands is ...

... 180° -135° = 45°

If SDE ~ SWT, find WT.

faust18 [17]

Formula used: 40+x = 4x-3 x is used for ET

Step-by-step explanation:

40+x = 4x-3

+3 +3

43+x = 4x

-x -x

43 = 3x

3 3

14.3 = x

then substitude this on 5x+3 on WT and you arr good
