Find the measure of angle A
Answer:
21 degrees
Step-by-step explanation:
Triangles have a total angle of 180 degrees.
This makes our equation:
3x+3+4x+135=180
Subtract 135 from both sides and combine like terms
7x + 3 = 45
Subtract 3 from both sides
7x = 42
Divide both sides by 7
x = 6
Plugging the number in:
3x + 3 =
3(6) + 3 =
21
Solve for x.
2/5x = 6/5
A: x = 12/25
B: x = 12/5
C: x = 3
D: x = 6
Answer:
C. x = 3
Step-by-step explanation:
2/5(3) = 6/5
6/5 = 6/5, correct!
MIGHTY MT. EVEREST
The Earth’s surface is composed of gigantic plates that are constantly moving. Currently, India lies on a plate that is slowly drifting northward. India’s plate is grinding into the rest of Asia. As it does so, it pushes up the Himalayan Mountains, which contain the world’s highest peak, Mt. Everest. In 1999, mountain climbers measured Mt. Everest with satellite gear and found it to be 8850 meters high. Geologists estimate that Mt. Everest may be growing by as much as 5 cm per year.
Your Task: Assuming a constant growth of cm per year, determine how tall Mt. Everest was in the year 0. (The year 0 is the year that came 2000 years before the year 2000.) Write an equation for the height of Mt. Everest over time, with x representing the year and y representing the height of the mountain.
What are the units for m and b in your equation? How many decimal places should be in your answer? Explain why.
The general equation representing the height of Mt. Everest over time can be written as → y = 0.05x + 8850. The unit of 'b' is meters and 'm' is a dimensionless quantity.
What is a time - varying quantity?A quantity whose magnitude is a function of time is called a time - varying quantity. For example → x = 2t.
Given is the measured height of Mt. Everest with the help of satellite gear. Geologists estimate that Mt. Everest is growing by as much as 5 cm per year.
Height of Mount Everest in the year 1999 → 8850 meters.
Rate at which Mt. Everest grows per year → 5 cm/yr = 1/20 m/yr.
The general equation representing the height of Mt. Everest over time can be written as →
y = 0.05x + 8850
where -
'x' represents the year.
'y' represents the height of the mountain.
The general equation of a straight line is given by -
y = mx + b [ m → slope, b → y-intercept ]
'y' represents height and is measured in meters. The slope 'm' of line is a dimensionless quantity as it the ratio of two lengths (y/x) and 'b' is measured in meters.
Now for x = - 2000
y = - 100 + 8850
y = 8750 m
Therefore, the general equation representing the height of Mt. Everest over time can be written as → y = 0.05x + 8850. The unit of 'b' is meters and 'm' is a dimensionless quantity.

SAVINGS Natalie has $250 in her savings accountinto which she deposits $10 of her allowance each week. The balance of her savings account can be modeled by the function f(w) = 250 + 10w , where w represents the number of weeks. Write a function g(w) to represent the balance of Natalie's savings account if she withdraws $40 to purchase a new pair of shoes. Describe the translation of f(w) that results in g(w) .
Answer:
[tex]g(w) = 210+ 10w[/tex]
Step-by-step explanation:
Given
[tex]f(w) = 250 + 10w[/tex]
[tex]Withdrawal = \$40[/tex]
Required
Determine g(w)
First, we'll write an expression for g(w)
From the question, we understand that she withdrew $40 from her account balance in w weeks.
This implies that:
[tex]g(w) = f(w) - 40[/tex]
Where f(w) is the account balance in w weeks and $40 is the withdrawn amount
Substitute 250 + 10w for f(w)
[tex]g(w) = 250 + 10w - 40[/tex]
Collect Like Terms
[tex]g(w) = 250 - 40+ 10w[/tex]
[tex]g(w) = 210+ 10w[/tex]
Recall that:
[tex]g(w) = f(w) - 40[/tex]
This means that function f(w) when shifter by 40 units downward, gives g(w)

a. B, C, A
b. C, A, B
C. B,A,C
d. A,B,C
e. A,C,B
f. CB, A
Answer:
The list of angles of the triangle in order from smallest to largest will be: A < C < B
Hence, option 'e' is true.
i.e (A,C,B)
Step-by-step explanation:
We know that in a triangle the greater angle has the longer side opposite to it.
From the given triangle,
Side AC = 7.2 is the longer side. Thus, B is the largest angle as it is opposite to the longer side AC = 7.2.
Then comes the second-longest side AB=4.9. Thus, C is the 2nd largest angle it is opposite to the second-longest side AB=4.9.
Finally comes the shortest side BC = 3.2. Thus, A is the shortest angle as it is opposite to the shortest side BC = 3.2.
Thus, the list of angles of the triangle in order from smallest to largest will be: A < C < B
Hence, option 'e' is true.
i.e (A,C,B)
The cost of making a phone is $152. A store sells the phone for $281.20.
Select all the expressions that could be used to find the percentage of markup for the phone.
Answer:
The store is selling the phone by 185% of its value...
Step-by-step explanation:
You just gotta divide 281.20 (the value of the phone at the store), and divide it up by 152 (its original value). And multiply the result by 100 to get the percentage.
[tex](\frac{281.00}{152})(100) = (1.85)(100) = 185%[/tex]%

Step-by-step explanation:
Suzie had a 49-question quiz, and she received 59.2%, but 12 questions weren't graded yet.
If all 12 questions are correct, what is the new percentage?
Based on the number of questions in the quiz that Suzie did, if 12 questions were not graded and they were all correct, the new percentage on the quiz is 69.4%
How to find the new percentage?There were 49 questions in the quiz and 12 were not graded. The number that was graded was;
= 49 - 12
= 37 questions
She got 59.2% which means that the number of questions Suzie got correct were:
= 37 x 59.2%
= 21.9
= 22 answers
If the 12 questions were correct, the new percentage would be:
= (22 + 12) / 49 x 100%
= 34 / 49 x 100%
= 0.693877551 x 100%
= 69.4%

Which value of m will create a system of parallel lines with no solution?
y=mx-6
8x-4y=12
Answer:
m = 2
Step-by-step explanation:
Rearrange the second equation into slope-intercept form (so that it is formatted the same as the first equation)
8x - 4y = 12
8x - 8x - 4y = -8x + 12
-4y = -8x + 12
-4y/-4 = (-8x + 12)/-4
y = 2x - 3
The slope for this equation is 2.
Equations with the same slope are parallel and therefore have no solution since they can never intersect. Hence, the required value of m is 2.

Blank 1:
Step-by-step explanation:
the slope is (y coordinate change / x coordinate change) when going from one point on the line to another.
it does not matter in what direction we go, but it is important to keep the same direction for the x and the y comparison.
because I prefer to go from left to right, let's go from
(-3, -4) to (5, 12).
x changes by +8 (from -3 to 5).
y changes by +16 (from -4 to 12).
so, the slope is
+16/+8 = 2/1 = 2
What is the slope of the line that passes through the points listed in the table.
