Answer: Option A: The entire expression is a sum.

Option C: The term is a quotient are true statements.

Step-by-step explanation:

Determine which statements are true:

Option A: The entire expression is a sum.

All of the given terms are additions. Thus, it is true not false.

Option B: The coefficient of s is 3.

False ,s has no denominator 3 in it. In the equation for s, the coefficient is .

Option C: The term is a quotient.

The dividend is 7, the divisor is r, and the quotient is 7. So, It's true.

Option D: The term has a variable.

False, variables are not present in the term.

In analysis, Option A: The entire expression is a sum, and Option C: The term is a quotient are true statements.

Answer:

C. $9\pi$

Step-by-step explanation:

We proceed to solve for $x$ by the Pythagorean Theorem:

$(x+1)^{2} = (x-1)^{2} + (2\cdot x - 4)^{2}$ (1)

$x^{2} + 2\cdot x + 1 = (x^{2}-2\cdot x + 1) + (4\cdot x^{2}-16\cdot x + 16)$

$x^{2} + 2\cdot x + 1 = 5\cdot x^{2}-18\cdot x + 17$

$4\cdot x^{2} -20\cdot x + 16 = 0$

$(2\cdot x)^{2} -10\cdot (2\cdot x) + 16 = 0$

$(2\cdot x -8)\cdot (2\cdot x -2) = 0$

There are two different solutions:

$x_{1} = 4$ , $x_{2} = 1$

A solution of $x$ is considered realistic when the length of every side of the triangle is a not negative number.

$x_{1} = 4$

$UV = 2\cdot (4) - 4$

$UV = 4$

$WU = 4 - 1$

$WU = 3$

$WV = 4 + 1$

$WV = 5$

$x_{2} = 1$

$UV = 2\cdot (1) - 4$

$UV = -2$

$WU = 1 - 1$

$WU = 0$

$WV = 1 + 1$

$WV = 2$

The only realistic set of solutions is for $x = 4$ , and the radius of the circle is represented by the line segment $WU$ : $r = 3$

And the area of the circle ( $A$ ) is calculated from the following formula:

$A = \pi\cdot r^{2}$

$A = \pi\cdot (9)$

$A = 9\pi$

The correct answer is C.

Answer:

AB = 25 units

Step-by-step explanation:

In right triangle ACB, $CD\perp AB$

Therefore, by geometric mean property:

$CD^{2} ={AD\times DB} \\ \\ {10}^{2} = AD\times 5 \\ \\ 100 = 5AD \\ \\ AD = \frac{100}{5} \\ \\ AD = 20$

AB = AD + DB

AB = 20 + 5

AB = 25 units

How many tenths are in 15.03

Brilliant_brown [7]

There are 10 "tenths" in one whole number.

15 --> 15 whole numbers --> 15 * 10 = 150 --> 150 tenths

0.03 --> 3 hundredths --> 10 hundredths = 1 tenth --> 3/10 tenth

150 3/10 tenths in 15.03
