Answers
Answer:
33
Step-by-step explanation:
The two angles add up to 180 degrees because a straight line is 180 degrees
Add both equations and set equal to 180
3m + 138 + 7m +12 = 180
Algebra yeet
Simplify
10m +150 = 180
10m = 30
m = 3
Angle DBC is (7m + 12):
Substitute m = 3
7(3) + 12 = 21 + 12 = 33 degrees

The school nurse took care of five students on Monday and four of the five students had a cough. The school nurse determined that 80% of the students in her school were coming down with colds. Which of the following would best describe why her conclusion was invalid?
Answers
Answer:
It is not valid because she only saw 5 students and that's not a large enough sample for the whole school.
Step-by-step explanation:
While 4/5 IS 80%, the nurse assumed that 80% of ALL of the students in the school were coming down with colds. This is not true since only 4 students had colds. If she were specific and said that 4/5 students who visited her on Monday were 80% coming down with colds, she'd be right. But she isn't since she's assuming it's 80% of the whole school's population of students.

Answers
Answer:
y = 3x
Step-by-step explanation:
m = (6-3)/(2-1) = 3/1 = 3
Answer: y=3x
Step-by-step explanation:
To write an equation, the first step is to look at the rise/run. In this graph, the rise is 3 and the run is 1. 3 divided by 1 is still 3 so in the equation mx+b, the m, also known as the slope, would be 3.
3x+b
And the b is the y-intercept where the line crosses the y axis.
3x+0=y
Therefore;
3x=y

Thandi received 15% discount on a dress that costs R1500. How much did she
pay?
Answers
Answer:
She paid $1,275.00.
Step-by-step explanation:
I'm assuming you meant $1,500, so I'll be using that.
You can figure this out by subtracting 15% of 1,500 from 1,500.
15% of 1,500 is 225.
1500-225=1275
Therefore, 15% off of $1,500 is $1,275.

Mold A
Mold B
Mold C
Mold D
Answers
Answer:
mold B
Step-by-step explanation:
The molds are of cylindrical shape. The volume of a cylinder is given by:
Volume = πr²h
where r is the radius and h is the height.
For mold A: diameter = 2 inches, hence radius = 1 inch. Height = 7 inches
volume = π(1²)7 = 7π in³
For mold B: diameter = 2 inches, hence radius = 1 inch. Height = 4 inches
volume = π(1²)4 = 4π in³
For mold C: diameter = 3 inches, hence radius = 1.5 inch. Height = 3 inches
volume = π(1.5²)3 = 6.75π in³
For mold C: diameter = 4 inches, hence radius = 1.5 inch. Height = 3 inches
volume = π(2²)3 = 12π in³
Therefore mold B has the smallest volume

[tex]\huge\boxed{\boxed{12a-60}}[/tex]
Step-by-step explanation:
Hello.
The Distributive Property states that
a(b+c)=ab+ac
Where
a, b, and c can be either constants or variables
we distribute a by multiplying it times b and c, and simplify if necessary.
In this case, we should distribute 12:
12(a-5)
12 times a and 12 times (-5):
12a-60
And we're done!
I hope it helps & have an outstanding day!

A line with a slope of 5 passes through the point (1,9). What is its equation in slope-intercept form? Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answers
Answer:
y = 5x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 5, then
y = 5x + c ← is the partial equation
To find c substitute (1, 9) into the partial equation
9 = 5 + c ⇒ c = 9 - 5 = 4
y = 5x + 4 ← equation of line
The Monday after Thanksgiving is called Cyber Monday. Amazon is
offering deals on many popular items. The same drone helicopter
is normally sold for $179.99, but on Cyber Monday, Amazon will be
selling it for $125.99. What is the percent change on the drone. Round to the nearest percent
Answers
Answer:
the percentage change on the drone is 42.86%
Step-by-step explanation:
The computation of the percentage change is shown below:
Since the helicopter was sold for $179.99
But amazon would be selling it for $125.99
So, the percentage change would be
= (Sale value - sale value by amazon) ÷ ( sale value by amazon) × 100
= ($179.99 - $125.99) ÷ ($125.99) × 100
= 42.86%
Hence, the percentage change on the drone is 42.86%
