Triangles add to 180 so you can do 42+60= 102 now add that to 14 which is 116 so your new equation is (8x+116)=180 so now 180-116= 64 and 8/64 = 8

If you have a density of 3g/ml and a volume of 10 ml, what is the mass?
balandron [24]

Alright, lets get started.

If you have a density of 3g/ml and a volume of 10 ml

means density = 3 g / ml

Volume = 10 ml

Formula for density, mass,  volume will be

density = \frac{mass}{volume}

Plugging the value

3 = \frac{mass}{10}

Multiplying 10 in both sides

10*3 = \frac{mass}{10} *10

mass = 30 gm

Hence the answer is 30 gm.   :    Answer

Hope it will help :)

Write the equation in slope-intercept form. What are the slope and y-intercept? -12x-4y=10
siniylev [52]

Answer:

  y = -3x -2.5

  slope: -3

  y-intercept: -2.5

Step-by-step explanation:

Solve for y.

  -4y = 12x + 10 . . . . . add 12x to get the y-term by itself

  y = -3x -2.5 . . . . . . .divide by the coefficient of y

__

The slope is the coefficient of x, -3.

The y-intercept is the constant, -2.5.

The table shows the cumulative number of minutes Alice practices clarinet for the first part of the school year. The values will
Mariulka [41]

The option (C) x-axis, scale: 1 unit = 1 week and y-axis, scale: 1 unit = 150 minutes with origin (0 weeks, 0 minutes) is correct.

<h3>What is a scale factor?</h3>

The ratio among comparable dimensions of an object and a model with that object, known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.

As we can see in the table, data is given, we can plot it in the graph by using the scale factor.

On the x-axis, scale: 1 unit = 1 week

On the y-axis, scale: 1 unit = 150 minutes

On the y-axis, 2 units = 300 minutes

On the y-axis, 3 units = 450 minutes

Thus, the option (C) x-axis, scale: 1 unit = 1 week and y-axis, scale: 1 unit = 150 minutes with origin (0 weeks, 0 minutes) is correct.
