Answer

$3 \frac{5}{6}$

Step by step explanation

$7 = 6 \frac{6}{6}$

$6 \frac{6}{6} - 3 \frac{1}{6} = 3 \frac{5}{6}$

Answer:

The answer is 42/19 or 2 4/19

Step-by-step explanation:

You have to divide 7 by 19/6. I say "19/6" because that's an improper fraction. You do " 7/1 divided by 19/6". Then you do KCF (Keep Change Flip). So you do "7/1 times 6/19". So now you just multiply across. And there's your answer (42/19) If you want to do a mixed number then you get 2 4/19.

Which statement is true about the angles?

liq [111]

Complete Question:

Triangle abc has the angle mesausres shown.

m<A = (2x)°

m<B = (5x)°

m<C = (11x)°

Which statement is true about the angles?

A. m<A = 20°

B. m<B = 60°

C. m<A and m<B are complementary

D. m<A + m<C = 120°

Answer:

A. m<A = 20°

Step-by-step explanation:

m<A + m<B + m<C = 180° (sum of interior angles of a triangle)

$2x + 5x + 11x = 180$ (substitution)

Solve for x. Add like terms.

$18x = 180$

Divide both sides by 18

$\frac{18x}{18} = \frac{180}{18}$

$x = 10$

Find the measure of each angle by substituting x = 10:

m<A = (2x)° = 2(10) = 20°

m<B = (5x)° = 5(10) = 50°

m<C = (11x)° = 11(10) = 110°

Therefore, the only true statement is:

A. m<A = 20°

Find the volume of a cone with radius 4 inches and height 5 inches. Round your answer to two decimal places

faltersainse [42]

Answer:

Volume of the cone = $83.73$ cubic inches

Step-by-step explanation:

Given:

Radius of the cone= $4 inches$

Height of the cone= $5 inches$

Volume of a cone(V) :

$\pi *r^2*\frac{h}{3}$

Putting the given values in the formula:

Volume of the cone:

$3.14*4*4*\frac{5 }{3}$ : $\pi =\frac{22}{7} =3.14$

$16*3.14*\frac{5}{3}$

$83.73$ cubic inches

So, the volume of the cone up to two decimal places is $83.73$ cubic inches

Determine whether each first-order differential equation is separable, linear, both, or neither. 1. ????y????x+????xy=x2y2 2. y+

Mkey [24]

Answer:

a) Linear

b) Linear

c) Linear

d) Neither

See explanation below.

Step-by-step explanation:

a) $\frac{dy}{dx} +e^x y = x^2 y^2$

For this case the differential equation have the following general form:

$y' +p(x) y = q(x) y^n$

Where $p(x) =e^x$ and $q(x) = x^2$ and since n>1 we can see that is a linear differential equation.

b) $y + sin x = x^3 y'$

We can rewrite the following equation on this way:

$y' -\frac{1}{x^3} y= \frac{sin (x)}{x^3}$

For this case the differential equation have the following general form:

$y' +p(x) y = q(x) y^n$

Where $p(x) =-\frac{1}{x^3}$ and $q(x) = \frac{sin(x)}{x^3}$ and since n=0 we can see that is a linear differential equation.

c) $ln x -x^2 y =xy'$

For this case we can write the differential equation on this way:

$y' +xy = \frac{ln(x)}{x}$

For this case the differential equation have the following general form:

$y' +p(x) y = q(x) y^n$

Where $p(x) =x$ and $q(x) = \frac{ln(x)}{x}$ and since n=0 we can see that is a linear differential equation.

d) $\frac{dy}{dx} + cos y = tan x$

For this case we can't express the differential equation in terms:

$y' +p(x) y = q(x) y^n$

So the is not linear, and since we can separate the variables in order to integrate is not separable. So then the answer for this one is neither.

Work the following problems using the table. Choose the correct answer.

kakasveta [241]

Answer:

option 3

$46.02

Step-by-step explanation:

First we have to look at the value of the French francs with respect to the dollars, we will look at the option of Wednesday which is how the problem asks.

if we see in the table it tells us that every 1 french franc gives us 0.2301 dollars

Now if we have 200 French francs, how many dollars will they give us?

1 = 0.2301

200 = ?

200 * 0.2301 / 1 =

46.02
