The required measure of an angle is ∠COD = 40°.
What are the vertical angles?When two lines intersect at a location, vertical angles are generated. They are always equal to each other.
Let's call the measure of [tex]$\angle COE$[/tex] x degrees.
Since [tex]$\overrightarrow{OD}$[/tex] divides [tex]$\angle COE$[/tex] into two angles of equal measure, the measure of each of those angles is [tex]$\frac{x}{2}$[/tex] degrees.
Since the measure of [tex]$\angle COB$[/tex] is 7 times the measure of [tex]$\angle BOF$[/tex], we have [tex]$\angle COB = 7\angle BOF$[/tex]. The sum of the measures of the angles of a triangle is [tex]$180^\circ$[/tex], so we can set up the equation [tex]$\angle COB + \angle COE + \angle BOF = 180^\circ$[/tex]. Substituting [tex]$7\angle BOF$[/tex] for [tex]$\angle COB$[/tex], we have:
[tex]$7\angle BOF + x + \angle BOF = 180^\circ$[/tex]
Solving for [tex]$\angle BOF$[/tex], we find that [tex]$\angle BOF = 20^\circ$[/tex].
The measure of [tex]$\angle COD$[/tex] is equal to the measure of[tex]$\angle COE$[/tex] minus the measure of [tex]$\angle COD$[/tex], so [tex]$\angle COD = x - 2\cdot 20^\circ = x - 40^\circ$[/tex].
Since the measure of [tex]$\angle COE$[/tex] is equal to [tex]$2\angle COD$[/tex], we have [tex]$x = 2(x - 40^\circ)$[/tex], which simplifies to [tex]$x = 80^\circ$[/tex].
Therefore, the measure of [tex]$\angle COD$[/tex] is [tex]$80^\circ - 40^\circ = {40^\circ}$[/tex].

Gia can run 4 miles in 32 minutes. At that rate, how many miles can she run in 40 minutes
Answer:
5
Step-by-step explanation:
For these types of problems, we can use cross - multiplication.
4/32 = x/40
Notice that since 40 and 32 are both measured in minutes, we put them on the same line.
Now, like the name suggests, we cross multiply the equation, by doing 4 * 40 = 32 * x. Now, we are left with 160 = 32x. After solving this, we get the answer 5.

A plane is flying at a steady speed of 30000m/minute.
How long does it take to fly 2000m. Give your answer in seconds.
SHOW METHOD AND EXPLAIN
Answer:
4 seconds
Step-by-step explanation:
[tex]\frac{30,000}{1} =\frac{2,000}x}[/tex]
The numerator is the distance and the denominator is the time.
I used cross multiplication, the numerator of one fraction times the denominator of the other.
[tex]30,000*x=2,000*1\\30,000x=2,000[/tex]
divide both sides by 30,000 and simplify
[tex]x=\frac{2,000}{30,000} \\x=\frac{2}{30}[/tex]
Then multiply the fractions by 2/2 (basically multiplying the numerator and the denominator each by 2)
[tex]x=\frac{4}{60}[/tex]
Since the denominator is 60, the number of seconds in a minute, the numerator is the answer
I hope this makes sense ;-;

Answer
12. x = 15, y = 21
13. x = 10, M = 37, N = 84, P =59
14. x = 19, R = 43, S = 20, T = 117
15. A = 21, B = 125, C = 34
16. J = 48, K = 57, L = 75
Explanation
12. 6x - 11 + x + 5 + 81 = 180
7x + 75 = 180
7x = 105
x = 15
4y - 18 + y + 14 + 6*15 - 11 = 180
5y + 75 = 180
5y = 105
y = 21
13. 4x - 3 + 9x - 6 + 6x - 1 = 180
19x - 10 = 180
19x = 190
x = 10
M = 4*10 - 3 = 37
N = 9*10 - 6 = 84
P = 6*10 - 1 = 59
14. R = 2x + 5
S = x + 1
T = 7x - 16
2x + 5 + x + 1 + 7x - 16 = 180
10x - 10 = 180
10x = 190
x = 19
R = 2*19 + 5 = 43
S = 19 + 1 = 20
T = 7*19 -16
15. A = C -13
B = 4C - 11
c - 13 + 4c - 11 + c = 180
6c -24 = 180
6c = 2-4
C = 34
A = 34 - 13 = 21
B = 4*34 - 11 = 125
16. K = J + 9
L = 2J -21
j + 9 + 2j - 21 + j = 180
4j -12 = 180
4j = 192
J = 48
K = 48 + 9 = 57
L = 2*48 -21 = 75

A $300 computer has a 35% tax. What is the cost of the tax?
A) $150
B) $200
C) $80
D) $105
Answer:
D : $105
Step-by-step explanation:
I use Proportional Reasoning.
part percent
whole 100 is the formula.
We are looking for the part so we will keep that as "x"
x 35
300 100
100 x 3 is 300. So 35 x 3 is 105. Thats the answer!

Choose 1 answer:
X = 2 5
x = -2 +5
x = 2 + 5
x = -2 + 5
Answer:
1) (x - 2)² = 25 2) x = 2 ± 5Step-by-step explanation:
[tex]24 = x^2 - 4x + 3\\\\ x^2 - 4x + 3-24=0\\\\\underbrace{x^2-2\cdot x\cdot2+2^2}-2^2-21=0\\\\{}\qquad(x-2)^2-25=0\\\\{}\qquad\bold{(x-2)^2=25}\\\\{}\qquad x-2=\pm\sqrt{25}\\\\{}\qquad \bold{x=2\pm5}[/tex]
the required equation for 1 is (x - 2)² = 25 and solution for 2 is x = 2 ± 5
What is the equation?The equation is the relationship between variables and is represented as y =ax + b is an example of a polynomial equation.
part 1
Given equation,
x² - 4x + 3 = 24
x² - 4x + 4 - 4 + 3 = 24
(x - 2)² - 1 = 24
(x - 2)² = 24 + 1
(x - 2)² = 25
Part 2
Solution for the given equation that transformed in part 1 of the solution.
(x - 2)² = 25
(x - 2) = √25
(x - 2) = ±5
x = 2 ± 5
Thus , the required equation for 1 is (x - 2)² = 25 and solution for 2 is x = 2 ± 5

Brian rolls a fair dice 60 times.
How many times would Brian expect to roll a three?
Answer:
10 times.
Step-by-step explanation:
He rolls all the dice independently, so The expected number of 3's is 60 * (expected number of 3's in one throw).
The expected number of 3's in one throw is:
5/6 * 0 + 1/6 * 1 = 1/6
because 5/6 of the time we roll zero 3's and 1/6 of the time we roll one 3 :D
So he should expect (60 * 1/6 = 10) 3's in 60 throws.
how do i solve substitution
