Answer:
12.25Step-by-step explanation:
It is easy to notice that:
QA=QB=QCAs per triangle congruence theorem (two congruent sides and a right angle)
Since:
QB = x + 9 and QC = 5x - 4We have
x + 9 = 5x - 45x - x = 9 + 44x = 13x = 13/4x = 3.25QA = QB = QC = 3.25 + 9 = 12.25

2. 3x+2-2=17-2 ( we subtract 2 from both sides)
3. then we simplify 3x=15
4. \frac{3x}{3}=\frac{15}{3} then i divide both sides by 3
5. and as we simplify, x=5
divide a line of 1.8m into three parts in the ratio of 5:7:8
Answers
Answer:
0.45 m, 0.63 m, 0.72 m
Step-by-step explanation:
Let the three parts of the line be 5x, 7x and 8x
Therefore,
5x + 7x + 8x = 1.8
20x = 1.8
x = 1.8/20
x = 0.09
5x = 5*0.09 = 0.45 m
7x = 7*0.09 = 0.63 m
8x = 8*0.09 = 0.72 m

The half-life of the radioactive element unobtanium-43 is 10 seconds. If 48 grams of unobtanium-43 are initially present, how many grams are present after 10
seconds? 20 seconds? 30 seconds? 40 seconds? 50 seconds?
Answers
Answer:
At time, 10 seconds, the mass remaining is 24 grams
At time, 20 seconds, the mass remaining is 12 grams
At time, 30 seconds, the mass remaining is 6 grams
At time, 40 seconds, the mass remaining is 3 grams
At time, 50 seconds, the mass remaining is 1.5 grams
Step-by-step explanation:
Given;
initial mass of the radioactive element = 48 grams
half life, t = 10 seconds
time of decay (s) remaining mass of the radioactive element
0 ------------------------------------------------- 48 grams
10------------------------------------------------- 24 grams
20 ------------------------------------------------- 12 grams
30 -------------------------------------------------- 6 grams
40 --------------------------------------------------- 3 grams
50 ----------------------------------------------------- 1.5 grams
60------------------------------------------------------0.75 grams
Thus;
At time, 10 seconds, the mass remaining is 24 grams
At time, 20 seconds, the mass remaining is 12 grams
At time, 30 seconds, the mass remaining is 6 grams
At time, 40 seconds, the mass remaining is 3 grams
At time, 50 seconds, the mass remaining is 1.5 grams

For these problems,
x
will represent the number of items and
y
will represent the money.
The fixed costs for a certain item are $100 per week. The cost to produce each item is $6 per item.
Using this information, what is the cost equation? Give your answer in slope-intercept form:
Answers
Answer:
y = 6x + 100
Step-by-step explanation:
Slope-intercept form is y = mx + b, where m is the cost to produce each item and b is the fixed cost. Let's input the given values for m and b into the equation:
y = 6x + 100
This is the cost equation. $6 multiplied by x amount of items pluss the fixed cost of $100 gives you the total cost (y) to produce x amount of items.

in this equation m represents the slope.
Therefore 1/3 is the slope
1/3
Step-by-step explanation:
Answer: m = 1/3
Step-by-step explanation: Since the equation of this line is written

by the coefficient of the x term which in this case is 1/3.
Tell which angles are congruent to the given angle measure.
Answers
Generally:
- Vertical angles are congruent. An example of vertical angles on the diagram are angles 1 and 4; they are opposite each other on the two intersecting lines.
When two parallel lines are intersected by a transversal:
- Corresponding angles are congruent. Corresponding angles are angles on the same side of the transversal with corresponding positions, such as angles 2 and 5 in the diagram.
- Alternate interior angles are congruent. Angles 3 and 5 are an example of alternate interior angles on the diagram. They are contained within the interior of the two parallel lines, and are on opposite sides of the transversal.
- Alternate exterior angles are congruent. These angles lie on the outside of the parallel lines and on opposite sides of the transversal. Angles 1 and 7 are an example of alternate exterior angles.
Looking at the diagram, we can recognize that our given angle of 56° creates a vertical angle pair with angle 7; these angles are congruent. Additionally, since corresponding angles are congruent, angles 4 and 7 are congruent. Notice that angle 4 creates a vertical angle pair with angle 1, and that angle 1 also corresponds to the given angle.
Answer:The angles which are congruent to the given angle measure are:
∠1, ∠4 and ∠7
