Answer:
x = 20°
Step-by-step explanation:
Assuming parallel lines, the two angles marked with measures are complementary to each other.
45° +(5x +35°) = 180°
5x = 100° . . . . . . . . . . . . subtract 80° from both sides
x = 20° . . . . . . . . divide by 5

Comment on the geometry
Where a transversal crosses parallel lines, all of the obtuse angles are congruent, and all of the acute angles are congruent. Of course, the acute angles and obtuse angles are linear pairs, hence supplementary. (The only time this won't apply is when all angles are right angles.)
No lines are marked as parallel here, nor does any part of this problem statement say there are parallel lines. So, we cannot find the value of x if we're going strictly by what is shown in the diagram. In the absence of any information, we can only say that the angle marked with an x-expression must be between 0° and 180°.
0 ≤ 5x +35 ≤ 180 ... -35 ≤ 5x ≤ 145 ... -7 ≤ x ≤ 29.

Answer:
x = {-8 - √10, -8 + √10} exact answer
x = {-11.16, -4.84} decimal approximation
Step-by-step explanation:
2(x + 8)²+ 9 = 29
Subtract 9 from both sides
2(x + 8)² = 20
Divide both sides by 2
(x + 8)² = 10
Take the square root of both sides
x + 8 = ±√10
Subtract 8 from both sides
x = -8 ± √10
x = {-8 - √10, -8 + √10} exact answer
x = {-11.16, -4.84} decimal approximation

The percentage is 1/2 * 2/5 = 1/5 = 20%.
Answer:
The correct answer is 20%
Step-by-step explanation:
If you were to pick two marbles from the pile, there would be 30 different possible combinations. Out of the 30 possible combinations, 6 of them meet the requirement of green marble on the first pick and red marble on the second pick. The fraction that represents the situation would be [tex]\frac{6}{30}[/tex] or [tex]\frac{1}{5}[/tex], which would be equal to 20%, so that is the correct answer.

The responses to the given question can be defined as follows:
Step-by-step explanation:
Its color palette depends on how much radiation reaches the eyes or the intensity of it. If indeed the duration of a wave is less than 400 nm, it is called UV and much more than 750 nm simple pleasures light it is (IV). The shorter wavelength implies a much more frequent spectrum and lower frequencies are the longer wavelengths.
The shorter the distance, the higher it's indeed. Since the red duration has been longer, the intensity is low. The purple has a smaller range and a high frequency, on the other side. The wavelengths are shorter as well as the frequencies are lower than the red, and it will differ even as violet goes, Remember that even more power is provided with the longer the duration of color. That wave/frequency color rises and is longer the purple color is becoming the lowest color.

Please help me!!!!
Answers
Answer:
118°
Step-by-step explanation:
EDC is 31° and ECD has the same measure. (Triangle DEC is isosceles)
The total sum of angle EDC and ECD is 31 + 31 = 62°
The total sum of all the angle measures in a triangle is 180°, so just subtract 62 from 180 to get the measure of angle DEC.
180 - 62 = 118°

=> If we 15 is the why intercept, then it means when x = 0, y = 15. Now if the slope is 12.5x, it means that the graph is increasing by 12.5 units each time. This means if we say 15 + 12.5 + 12.5 (since we are given an x value for y = 2) we would get 40.00. And that we get, hence option D is the correct answer.

y = -x^2 + 99x - 932
Answers
Answer:
$49.5
Step-by-step explanation:
y = -x^2 + 99x - 932
The maximum point is :
dy/dx = 0
Take the first derivative of y
dy/dx = - 2x + 99
Put - 2x + 99 = 0
-2x = - 99
x = 99 / 2
x = 49.5
Hence, To make maximum profit, widget should be sold at $49.5 per widget.

Ayoub is driving to France for his holiday.
He will drive a total distance of 300 miles. Ayoub sets off at 07:15.
It takes him 2.5 hours to travel the first 125 miles.
Use this information to estimate the time Ayoub will arrive.
Answers
Answer:
10:30 hours
Step-by-step explanation:
Total distance=300 Miles, Start Time=07:15
Distance travelled so far is 125 miles for 2.5 hours
First we need to calculate Ayoub's speed as follows
Speed=Distance/Time
=125miles/2.5hour
=50 miles/hr
The calculate the remaining distance
=300-125
=175 Miles
Assuming that Ayoub Travels in the same speed at the first 300 miles, the time he will use to cover the remaining 175 miles is
Time=Distance/speed
Substituting the values
Time=175/50
=3.5 hours
The time he will arrive at Paris is
07:15+03:30
=10:30 hours
