In ΔXYZ, x = 5. 2 inches, y = 9. 8 inches and z=7. 1 inches. Find the measure of ∠Z to the nearest degree
The measure of ∠Z is 165 degrees to the nearest degree.
In a triangle, the measure of each angle is equal to the sum of the measures of the other two angles subtracted from 180 degrees. This is known as the Triangle Sum Theorem.
Given that x = 5.2 inches, y = 9.8 inches, and z = 7.1 inches in triangle XYZ, we can use the theorem to find the measure of angle Z.
∠Z = 180 - (x+y)
∠Z = 180 - (5.2+9.8)
∠Z = 180 - 15
∠Z = 165
So the measure of ∠Z is 165 degrees to the nearest degree.
Therefore, The measure of ∠Z is 165 degrees to the nearest degree.

Answer:
answer: 1/36 or 2.8%
Step-by-step explanation:
Green is the answer because probability for this will be found by doing the chances for both multiplied by each other there is a 1/6 chance of getting 5 so 1/6 x 1/6 = 1/36 so thats why green is the answer. Hope that helps!
During a football game the hawks lost 5 yards due to a penalty and lost 6 yards from a quarterback sack. Write and solve an expression that represents the situation.
An expression that describes the given situation is; Total yards = -6 - 5 and the solution is -11
How to solve basic number problems?
In mathematics, a positive number means we have a plus sign before the number which means if we have +2, it means that there has been a gain of 2 units. In a similar manner, a negative number represents a loss which means that if we have -3, it simply means there is a loss or reduction of 3.
Now, we are told that during a football game, the hawks lost 5 yards due to a penalty and lost 6 yards from a quarterback sack. Thus, using the concept of positive and negative numbers above, we can develop the total number of yards as;
Total yards = -6 - 5
Total yards = - 11 yards
This represents a loss.

What does += mean in Python?
In Python an operator += is an assignment operator which adds the value on its right to the variable and assigns the result to the variable on its left.
We know that an operator is a symbol that represents a mathematical or logical process.
We know that in Python the operator += provides a convenient way to add a value to an existing variable and assign the new value back to the same variable.
If p += q
This means, the variable p the left side is getting added to the value on the right side (q), and the result is then reassigned to the variable on the left.
i.e., p = p + q

35% of ____ = $3.50 find the unknown number
Answer:
10
Step-by-step explanation:
35% of x = 3.5 To change a percent to a decimal, divide by 100%
.35x = 3.5 Divide both sides by 3.5
[tex]\frac{.35x}{.35}[/tex] = [tex]\frac{3.5}{.35}[/tex]
x = 10
Check:
.35 x 10 = 3.3.5 = 3.5
Answer:
10
Step-by-step explanation:
Let the unknown number be x.
35% of x = 3.50
35/100 * x = 3.50
35x = 3.50 * 100
35x = 350
x = 350/35
x = 10
Hence, the unknown number is 10.

to get a test score of 40%.
Please Help
A student needs to receive 20 out of a possible 50 points on the test in order to receive a passing grade of 40%.
what is proportion ?The term "proportionate" refers to relationships that always have the same ratio. For instance, the average number of apples per tree influences how many trees there are in an orchard and how many fruits there are in a harvest of apples. A linear relationship between two numbers or variables is referred to in mathematics as being proportionate. In the same way as the first quantity doubles, so does the other. The other decreases as well when one of the variables is reduced to 1/100th of its previous value. When two quantities are proportional, it means that when one rises, the other rises as well and that the ratio between the two quantities is constant at all values. As an example, consider a circle's diameter and circumference.

Step-by-step explanation:
Can you form a triangle with side lengths 8 9 and 17?
No, you cannot form a triangle with side lengths 8, 9, and 17. The sum of any two sides of a triangle must be larger than the remaining side. 8 + 9 = 17, which is not larger than 17.
1. A triangle is a three sided polygon with three angles and three sides.
2. In order to form a triangle, the sum of any two sides of the triangle must be larger than the remaining side.
3. To test if a triangle can be formed with side lengths 8, 9, and 17, we need to add two of the sides together and see if the result is larger than the remaining side.
4. 8 + 9 = 17, which is not larger than 17, so a triangle cannot be formed with side lengths 8, 9, and 17.

Judiyah is the proud new owner of a chair making business. She makes custom wood chairs. She sells her custom chairs for
$150. The cost of rent and the expensive saws and equipment she bought add up to about $50 a chair. The wood she uses is
standard wood and the materials to make one chair cost about $30. She pays one worker to help her move the chairs into people's
home. Everytime she sells a chair, she pays this worker
$10 for the hour of work to transport the homemade chair.
What is judiyah’s profit ?
Answer:
$60
Step-by-step explanation:
Profit = revenue - total cost
cost is total expenses incurred in running the business
total cost = cost of rent and the expensive saws and equipment + cost of wood + amount paid to worker
50 + 30 + 10 = 90
revenue is the amount earned from selling the chairs. it is equal to 150
Profit = 150 - 90 = 60

If star a is closer to us than star b, then star a's stellar parallax is __________.
O Larger than that of star B
O Larger than that of star A
O Smaller than that of star B
O Smaller than that of star A
If star A is closer to us than star B, then Star A's parallax angle is: Larger than that of Star B.
Hence, option (A) is correct choice.
The parallax of a star at a distance of 10 parsecs would be 0.1′′ since parallax is inversely proportional to distance. The parallax of Proxima Centauri, a star in the triple system of Alpha Centauri, is 0.76813′′, indicating that it is 4.24 light-years away from Earth at a distance of 1/0.76813, or 1.302 parsecs.
The apparent shift in an object's location caused by a change in the observer position is known as parallax. This apparent shift is measured (in arc seconds) is reversed to provide the distance from the background stars (in parsecs).
The definition of an object's absolute magnitude is the apparent magnitude the object would have if it were observed at a distance of precisely 10 parsecs (32.6 light-years), without light extinction.
