Find MZA

(4x + 17)°
B
A
(3y - 20°
(2y + 1°
Need help with this question?
Answer:
m∠A is 89°
Step-by-step explanation:
By circle theorem, two or more inscribed angles subtended by the same arc are equal
Therefore, from the diagram, we have;
Angle (5·x - 1)° and angle (4·x + 17)° subtends the same arc DC
∴ (5·x - 1)° = (4·x + 17)°
We can write the angles as follows since they are both in degrees
(5·x)° - 1° = (4·x)° + 17°
(5·x - 4·x)° = 17° + 1°
x = 18°
m∠A = (5·x - 1)°
∴ m∠A = (5 × 18 - 1)° = (90 - 1)° = 89°
m∠A = 89°.

Put the following numbers in order from least to greatest: √42, 7, 6, √38.
Answer:
6, √38, √42, 7
Step-by-step explanation:
The numbers in order from least to greatest is 6,√38,√42,7
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Finding the least common multiples of the denominator expressions can help. Then using the similar method as we use in sum of fractions would give the sum of algebraic fractions.
Given;
√42, 7, 6, √38
√42=6.4
√38=6.1
Therefore, the order of algebra will be 6,√38,√42,7

If there are 520 grams of radioactive material with a half life of 12 hours how much of the radioactive material will be left after 72 hours? Is the radioactive decay modeled by a linear function or an exponential function
Answer:
16.25 grams are left
exponential
Step-by-step explanation:
Half the material will decay every 12-hour period (the other half will remain).
Initial amount (at time t = 0): 520 grams
Time t = 12: 260 grams are left
Time t = 24: 130 grams are left
Time t = 36: 65 grams are left
Time t = 48: 32.5 grams are left
Time t = 72: 16.25 grams are left
Radioactive decay is modeled by an exponential function. The function can't be linear because for them, equal time steps would produce equal reductions in the amount of material.

Ms. Clark spent $89.85 on sewing kits that cost $5 each plus $4.85 tax on the total bill. How many kits did she buy?
The sewing kits bought by Ms, Clark is 17 in number.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
As given in the question, Ms. Clark spent $89.85 on sewing kits that cost $5 each plus $4.85 tax on the total bill.
Let the number of sewing kits be x,
According to the question,
5x + 4.85 = 89.85
5x = 89.85 - 4.85
5x = 85
x = 17
Thus, the sewing kits bought by Ms, Clark is 17 in number.

Question 4 of 15
When asked to find the sum of two mixed numbers with different
denominators, you should before you add.
A. round each fraction
B. find the difference
C. find a common denominator
When asked to find the sum of two mixed numbers with different denominators, you should find a (C) common denominator before you add.
To add fractions with different denominators, it is necessary to find a common denominator for both fractions. Once the fractions have the same denominator, you can add or subtract the numerators while keeping the denominator unchanged. This allows for a meaningful addition of the fractions.
To find a common denominator, you need to determine the least common multiple (LCM) of the denominators. The LCM is the smallest multiple that both denominators can divide evenly into. Once you have the common denominator, you can convert each fraction to an equivalent fraction with that denominator and then perform the addition.
After finding the common denominator, you add the numerators of the fractions and keep the common denominator. This will give you the sum of the two mixed numbers with different denominators. The correct answer is C. find a common denominator.
