What is the answer to -20+5p-7z

Mathematics
1 answer:
kobusy [5.1K]3 years ago
6 0

" -20 + 5p - 7z " is not a question, and it doesn't beg for an answer.
It's an expression that stands for a number. 

In order to determine what the number is, you need to know the
values of 'p' and 'z'.  And if either of those changes, then the value
of " -20 + 5p - 7z " immediately changes too.  So the whole thing is
a 'moving target'.

Arisa [49]

Answer:

5.498 - C

Step-by-step explanation:

Length of an arc = tetha/360 × 2 × pi × r

Converting 7pi/4 to tetha

(7 × 180) / 4 = 315°, since pi = 180°

Plugging values to the formula:

315/360 × 2 × 3.142 × 1 = 5.498units

Mashutka [201]

Answer:

{ \tt{ \blue{  - {3x}^{2} + 4x + 4 }}}

Step-by-step explanation:

{ \tt{3x -  {2x}^{2}  + 4 -  {x}^{2} + x }} \\

» Collect second degree terms (x² coefficients) together and first degree terms (x coefficients) and constants

= { \tt{( - 2 - 1) {x}^{2} + (3 + 1)x + 4 }} \\  = { \boxed{ \tt{ \:  -  {3x}^{2}  + 4x + 4}}}

What is the value of x ??
ruslelena [56]

Answer:

A

Step-by-step explanation:

The Tangent-Secant Exterior Angle Measure Theorem states that if a tangent and a secant or two tangents/secants intersect outside of a circle, then the measure of the angle formed by them is half of the difference of the measures of its intercepted arcs. Basically, what that means here is that x equals half of the difference of 30\textdegree and the measure of the unlabeled arc.

First, we need to find the measure of the unlabeled arc, since we can't find x without it. We know that the measure of the full arc formed by the circle is 360\textdegree, so the measure of the unlabeled arc must be 360-30-100-100=130\textdegree by the Arc Addition Postulate.

Now, we can find x. Using all of the information known, we can solve for x like this:

\\x=\frac{1}{2} (130\textdegree-30\textdegree)\\=\frac{1}{2} (100\textdegree)\\=50\textdegree

Hope this helps!
