Answer:
8 and 8
Step-by-step explanation:
The magnitude of a number is the positive distance it is from the origin. The number 8 is 8 units from the origin (in the + direction). The number -8 is also 8 units from the origin (in the - direction).
Both 8 and -8 have a magnitude of 8 units.
How many sides do 2 octagons, 4 pentagons, and 5 triangles have in all?
Answer: 51
Step-by-step explanation:
2 octagons have 16 sides because an octagon has eight sides. So, 8x2=16.
4 pentagons have 20 sides because a pentagon has 5 sides. So, 4x5=20.
5 triangles have 15 sides because a triangle has 3 sides. So, 5x3=15.
In all, 16+20+15= 51
find the slope of the line through each pair of points (19,-2) (-11,10)
Answer:
[tex]\huge\boxed{-\frac{2}{5}}[/tex]
Step-by-step explanation:
The slope of a line can be determined from two points via the slope formula. This is usually defined as the change in y divided by the change in x. It’s commonly represented using this formula:
[tex]\displaystyle \frac{\Delta y}{\Delta x}[/tex]Where [tex]\Delta[/tex] represents “change in.”
The slope is basically just saying the rate of increase/decrease a function has when x increases by 1 - how much does y change when x increases by 1? We can find this by taking larger values and dividing by the rate at which we took the larger values. This derives the slope formula.
We can find the change in y and x in this function by analyzing the two points given. If we look at the change between each point, we can get the change since this is a line and thus has a constant slope.
The change in y will be 12. This is because from -2 to 10 is 10 units - [tex]10 - (-2) = 12[/tex] The change in x will be -30. This is because from 19 to -11 is -30 units - [tex]-19 -11 = -30[/tex]Now that we have our change in x and y, we can substitute these values into the slope formula.
[tex]\displaystyle \frac{\Delta y}{\Delta x}[/tex] [tex]\displaystyle \frac{12}{-30}[/tex] [tex]\displaystyle -\frac{12}{30}[/tex] Simplify - divide numerator and denominator by 6 [tex]\displaystyle -\frac{2}{5}[/tex]Therefore, the slope of this line is [tex]-\frac{2}{5}[/tex].

Directions: Solve for the surface area of the following figures using the formula.
no links pls. i really need it T-T
Answer:
3^3 x 3.14
9 x 3.14 = 28.26
28.26 x 2 = 56.52
2 x 3.14 x 3 = 18.84
18.84 x 10 = 188.4

b. 3 to 2
c. 6 to 5
d. 9 to 8
Please select the best answer from choices provided
Answer:
B. 3 to 2
Step-by-step explanation:
I calculated it logically
The ratio of the frequency of G to C is 1.5. So, option b is correct.
What is meant by frequency ?Frequency of a wave is defined as the number of oscillations completed by the wave in one second.
Here,
The frequency of note G, f(G) = 392 Hz
The frequency of note C, f(C) = 262 Hz
The ratio of the frequency of G to C, r = frequency of G/frequency of C
r = f(G)/f(C)
r = 392/262
r = 1.496 approximately r = 1.5
Hence,
The ratio of the frequency of G to C is 1.5

Part 3a. NO LINKS. Find the measure of the arc or angle indicated.
9514 1404 393
Answer:
99°
Step-by-step explanation:
Arc YZ is twice the measure of angle X, so is 136°. The sum of the arcs of a circle is 360°, so the unknown arc is ...
360° -136° -125° = 99° . . . . measure of arc XZ
Answer:
Solution given:
<x=68°
arc XY=125°
arc XZ=?
we have
<X+<W=180°[sum of opposite angle of a cyclic quadrilateral is supplementary]
<W=180°-68°=112°
Now
arc YZ=2×112°=224°[central angle is equal to the twice of its inscribed angle]
arc YZ=224°
arc XY +arc YZ=224°
125°+arc YZ=224°
arc YZ=224°-125°
arc YZ=99°
the measure of the arc or angle indicated is 99°.

what does mrs freeman pay for the meal
Answer:
Lin's father pay for the meal is $18.19
Step-by-step explanation:
Given:
Lin’s father is paying for a $20 meal.
He has a 15%-off coupon for the meal.
After the discount, a 7% sales tax is applied.
Now, to get the amount Lin's father pay for meal.
So, we deduct the 15% discount first:
$20 - 15% of $20.
Then, adding 7% sales tax:
$17 + 7% of $17
Therefore, Lin's father pay for the meal is $18.19.

A recent survey showed that 23.3 million adults have cut the cord on cable TV services, a 30% increase fron the previous year. If this trend continues, how many millions if adults can be expected to cut the cord next year?
Answer:
30,290,000 people
Step-by-step explanation:
The question is asking if the trend continues from the PREVIOUS year, so we would find the 30% of 23,300,000
23,300,000/100 = 233,000 = 1%
233,000 x 30 = 6,990,000
23,300,000 = 6,990,000 = 30,290,000
