Answer: x=−2.15

Step-by-step explanation : Alright Let's solve your equation step-by-step.

0.5x−2=1.5x+0.15

Step 1: Subtract 1.5x from both sides.

0.5x−2−1.5x=1.5x+0.15−1.5x

−x−2=0.15

Step 2: Add 2 to both sides.

−x−2+2=0.15+2

−x=2.15

Step 3: Divide both sides by -1.

−x

−1

=

2.15

−1

x=−2.15<em>        hope this helped!- Alex</em><u> </u>

Find the volume of the solid that lies inside both the cylinder x 2 y 2 = 1 and the sphere x 2 y 2 z 2 = 16
IrinaVladis [17]

The volume of the solid that lies inside both the cylinder x² + y² = 1 and the sphere x² + y² + z² = 16 is 24.74 cubic units.

<h3>What is the volume of the solid?</h3>

Find the volume of the solid that lies inside both the cylinder x² + y² = 1 and the sphere x² + y² + z² = 16

From the sphere and cylinder, the cylindrical coordinate will be

z = \pm \sqrt{16 - r^2}

And the radius of the cylinder is |r| < 1 and the 0 ≤ θ ≤ 2π.

Then the volume will be given as

\rm V = \int _0^{2\pi} \int _0^1 \int _{- \sqrt{16 - r^2}}^{\sqrt{16-r^2}} \left ( r \ dz \ dr \ d\theta  \right ) \\\\\\V = 2\pi \int_0^1 \left ( 2r\sqrt{16-r^2} \right ) \ dr\\\\\\V = 4\pi \left [ -\dfrac{1}{3} (16 - r^2)^{3/2} \right ]\\\\\\V = \dfrac{4\pi}{3} \left ( 16^{3/2} - 15^{3/2} \right )\\\\\\V = 24.74

More about the volume of the solid link is given below.

HELPPPPPP MEEEEEEEEEEEEEEEEEE PLEASSEEEEEEEE!!
12345 [234]

Consider the angles are = 60,2x,3x

As we know the sum of the interior angle of a triangle is 180

60+2x+3x= 180

5x= 120

x= 24°

Angles are 2x= 2(24)= 48°

and 3x= 72°

<em>The measure of smaller angle is 48°</em>

You owe $300 on your credit card. For every month that you fail to make a payment, your balance increases by 1%. Find a formula
Vlada [557]

Answer:

B(t) = 300(1.01)^{t}

Step-by-step explanation:

The balance owed after t months can be given by an exponential function in the following format:

B(t) = B(0)(1+r)^{t}

In which B(0) is the initial balance owed and r is the growth rate, as a decimal.

You owe $300 on your credit card. For every month that you fail to make a payment, your balance increases by 1%.

This means, respectively, that B(0) = 300, r = 0.01

So

B(t) = 300(1+0.01)^{t}

B(t) = 300(1.01)^{t}

A circle has a circumference of 10 inches. What is the radius of the circle?
fenix001 [56]
The formula for finding the radius of a circle while only knowing the circumference is r=C ÷ 2π. Substituting the value 10 for C, and 3.14 for π, we get:

r=10 ÷ 3.14 · 2         Now we divide 10 by 6.28
r≈1.59
