(question 31) if arc mBC =120 and arc mAD =50 whatis the measure of angle DYC
===============================================================
Explanation:
First, let's calculate angle BYC. This is the angle formed by the chords that subtend the arcs mentioned. This angle faces or is aimed toward the direction of the arcs. To find this angle, we'll average the arc measures like so:
angle BYC = (arcAD + arcBC)/2
angle BYC = (50+120)/2
angle BYC = 170/2
angle BYC = 85 degrees
Then we'll use the idea that angles BYC and DYC are supplementary (aka they form a straight 180 degree angle)
angleBYC + angleDYC = 180
angleDYC = 180 - angleBYC
angleDYC = 180 - 85
angleDYC = 95 degrees
which is why the answer is choice D.

Answer:
1. You should mix 5 cups of yellow paint with 1 cup of blue paint. The table shows that the ratio is 1:5 (blue:yellow) so 1 cup of blue paint means you need 5 cups of yellow paint.
2. Using the same ratio (1:5), you can multiply both numbers by any number and get the same shade of green.
5 cups of blue paint will need 25 cups of yellow paint.
(1 x 5 = 5 : 5 x 5 = 25)

Find the measure of the angle indicated in bold (7x + 10)
Also can you explain how you got the answer
Answer:
80°
Step-by-step explanation:
8x = 7x + 10
They are alternate(different sides of the intersecting or transversal line) interior(inside the two parallel lines)angles
alternate interior angles
8x = 7x + 10
x = 10
7(10) + 10 = 80

if f(x)=x-4 find the value if f(x)+f(-x)
Answer:
2x
Step-by-step explanation:
f(x) = x -4
Step 1:
y = x - 4
Step 2: Replace y with x
x = y - 4
Step 3: Find y
x + 4 = y
f(-x) = x + 4
f(x) + f(-x) = (x - 4)+ (x + 4) = 2x

a bank account balance for an account with an initial deposit of p dollars earns interest at an annual rate of r . the amount of money in the account after n years is described using the following expression p (1+r)n what effect if any does decreasing the value of r have on the amount of money after n years?
Answer:
Step-by-step explanation:
For the same exponent n and 1 < a < b we have
[tex]a^n < b^n[/tex]
Now if we decrease the r the value then 1 + r will also decrease.
If follows that the amount of money after n years will also decrease.

Answer:
∠LMP = 77
∠NMP = 103
Step-by-step explanation:
to find the measure of ∠LMP and ∠NMP
we know that ∠LMN is a straight line so that will be 180 degrees
so you can say that
∠LMP + ∠NMP = 180
(-16x +13) + (-20x +23) = 180
-16x +13 -20x + 23 = 180
-36x + 36 = 180
-36x = 180-36
-36x = 144
x = 144/-36
x = -4
∠LMP = (-16x +13)
= ( -16 (-4) + 13)
= ( 64 + 13)
= 77
∠LMP = 77
∠NMP = (-20x +23)
= (-20 (-4) + 23)
= 80 + 23
= 103
∠NMP = 103
Convert 19.3 picometers per squared kiloseconds (pm/ks^2) into megameter per squared nanoseconds (Mn/ns^2).
Unit conversion involves the conversion of a metric unit to another unit of the same quantity.
[tex]19.3 pm/ks^2[/tex] to megameter per squared nanoseconds is [tex]19.3 \times 10^{-41} Mn/ns^2[/tex]
Let:
[tex]x = 19.3 pm/ks^2[/tex]
Multiply by [tex]10^{-17[/tex] to convert megameter per squared kiloseconds
[tex]x = 19.3 \times 10^{-17} Mn/ks^2[/tex]
Divide by [tex]10^{24[/tex] to convert to megameter per squared nanoseconds
[tex]x = \frac{19.3 \times 10^{-17}}{10^{24}} Mn/ns^2[/tex]
Apply law of indices:
[tex]x = 19.3 \times 10^{-17-24} Mn/ns^2[/tex]
[tex]x = 19.3 \times 10^{-41} Mn/ns^2[/tex]
Hence:
[tex]19.3 pm/ks^2[/tex] to megameter per squared nanoseconds is [tex]19.3 \times 10^{-41} Mn/ns^2[/tex]

slove 3(n-4)+2(4n-5)=(n+2)
Answer:
n is 2.4
Step-by-step explanation:
[tex]3(n - 4) + 2(4n - 5) = (n + 2)[/tex]
open the brackets:
[tex](3n - 12) + (8n - 10) = (n + 2)[/tex]
collect like terms together:
[tex]3n + 8n - n = 2 + 12 + 10 [/tex]
factorise out n :
[tex]n(3 + 8 - 1) = 24 \\ 10n = 24 [/tex]
divide all sides by 10 :
[tex] \frac{10n}{10} = \frac{24}{10} \\ \\ n = 2.4[/tex]
