Help me with my math quiz from friday 4/1 <br> SHOW STEPS

malfutka [58]

Hie!! I will be solving the questions in the sequence of the attachments.

_______________________________________

4. As line SU and TV are intersecting each other at O.

A.T.Q, ∠UOV = (7x - 4)°

∠SOT = 87°

Then, ∠UOV = ∠SOT {Vertically Opposite Angles}

$\rightarrow\sf{7x - 4=87}$

$\rightarrow\sf{7x =87+4}$

$\rightarrow\sf{7x =91}$

$\rightarrow\sf{x =\frac{91}{7}}$

$\rightarrow\boxed{\bf{x =13}}$

_______________________________________

5. radius = 17ft

circumference of circle = 2πr

$\rightarrow\sf{circumference=2\times\frac{22}{7}\times17}$

$\rightarrow\boxed{\bf{circumference=106.8ft}}$

_______________________________________

3. ∠1 and ∠2 - add to 180 (linear pair)

∠1 and ∠3 - equal (Vertically Opposite Angles)

∠3 and ∠4 - add to 180 (linear pair)

∠2 and ∠4 - equal (Vertically Opposite Angles)

_______________________________________

2. 160° + (6x - 16)° = 180° (linear pair)

$\rightarrow\sf{6x - 16 = 180-160}$

$\rightarrow\sf{6x - 16 = 20}$

$\rightarrow\sf{6x = 20+16}$

$\rightarrow\sf{6x =36}$

$\rightarrow\sf{x =\frac{36}{6}}$

$\rightarrow\boxed{\bf{x =6}}$

Please help i will mark brainliest

Zielflug [23.3K]

Answer:

$\left[\begin{array}{ccc} -10 & -9 \\ -8 & -2 \\ -11 & 67 \end{array}\right]$

Step-by-step explanation:

This is a matrices. Since they are both the same in format, we can add them together. But first we must multiply each value by the given values.

$\left[\begin{array}{ccc}-30 & -5 \\ 20 & 30 \\ -35 & 35 \end{array}\right]$ + $\left[\begin{array}{ccc} 20 & -4 \\ -12 & -32 \\ 24 & 32 \end{array}\right]$ = $\left[\begin{array}{ccc} -10 & -9 \\ -8 & -2 \\ -11 & 67 \end{array}\right]$

Hope this helps! (Please consider giving brainliest)

If a2> 20, then which of the following could be a value of a?

PIT_PIT [208]

Answer:

Step-by-step explanation:

The square root of 20 = 4.47 so a for sure.

But the root of 20 is also -4.48 so that means that 2 and 3 are added to the list

Now what to do about - 8

(- 8)^2 = 64

The square root of 64 = +/- 8

It's kind of slippery but it depends on how you see the problem. It is a bit ambiguous.

I would eliminate - 8 but your instructor may not. Argue that it should not be included, but don't take the argument on forever. Let it go.

a for sure.

b and c I think so.

-8 is iffy.
