(02.07)A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle.
A triangle ABC is shown. The base of the triangle extends into a straight line. The angle formed between this straight line and the edge of the triangle is marked as p. The angle adjacent to p is marked as o, and the other two angles inside the triangle are marked as m and n.
Step 1: m∠m + m∠n + m∠o = 180 degrees (sum of angles of a triangle)
Step 2: m∠p − m∠o = 90 degrees (alternate interior angles)
Step 3: Therefore, m∠m + m∠n + m∠o = m∠o + m∠p
Step 4: So, m∠m + m∠n = m∠p
In which step did the student first make a mistake and how can it be corrected?
Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (corresponding angles)
Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (adjacent angles)
Step 2; it should be m∠o + m∠p = 180 degrees (alternate exterior angles)
Step 2; it should be m∠o + m∠p = 180 degrees (supplementary angles)
Answer:
I'm pretty sure it's the last option. Step 2; it should be m<o+m<p=180 degrees (supplementary angles)
Step-by-step explanation:
I think it's the last one since m<o and m<p are supplementary.
What is the scale factor of ABC to DEF?
Answer:
The answer is 8.
Step-by-step explanation:
Since you are looking for the scale factor of ABC to DEF the answer is 8 because DEF is 8 times larger than ABC.
The scale factor of ABC to DEF would be 1/3 Thus, the correct option is B.
What is the scale factor?The scale factor states the scale or measurement by which a figure is bigger or smaller than the other figure. The size by which the figure would be reduced or enlarged is called its scale factor.
In a triangle ABC and DEF
The sides are as follows 5 to 15 which is thrice the length of the side in ABC.
4 to 12 which is 3 times the length of the side in ABC.
3 to 9 which is 3 times the length of the side in ABC.
Thus, the scale factor would be 1/3.

A 6 ft tall person walks away from a 10 ft lamppost at a constant rate of 3 ft/s. What is the rate (in ft/s) that the tip of the shadow moves away from the pole when the person is 15 ft away from the pole
Answer:
12.5 ft/s
Explanation:
Height of person = 6 ft
height of lamp post = 10 ft
According to the question,
dx / dt = 5 ft/s
Let the rate of tip of the shadow moves away is dy/dt.
According to the diagram
10 / y = 6 / (y - x)
10 y - 10 x = 6 y
y = 2.5 x
Differentiate both sides with respect to t.
dy / dt = 2.5 dx / dt
dy / dt = 2.5 (5) = 12.5 ft /s
At what interest rate will P20,000 accumulate to P26,080 in 8 years time?
Answer:
Rate of interest = 3.8%
Step-by-step explanation:
Given:
Initial amount p = 20,000
Final amount p + I = 26,080
Number of year t = 8 year
Find:
Rate of interest
Computation:
I = 26,080 - 20,000
I = 6,080
I = PRT
6,080 = (20,0000)(r)(8)
Rate of interest = 3.8%

5(2t - 3) – 7.5t = 0.5(12 – t)
PLEASEEEE HELP ME
Answer:
t = 7
Step-by-step explanation:
5(2t - 3) – 7.5t = 0.5(12 – t)
5*2t - 3*5 - 7.5t = 12*0.5 - t *0.5
10t - 15 - 7.5t = 6 - 0.5t {Now, combine like terms}
10t - 7.5t - 15 = 6 - 0.5t
2.5t -15 = 6 - 0.5t {Add 15 to both sides}
2.5t = 6 - 0.5t + 15
2.5t = 21 - 0.5t { Add 0.5t to both sides}
2.5t + 0.5t = 21
3t = 21 {Divide both sides by 3}
t = 21/3
t = 7

Ken made $14,500 in five months at his new job. How much can he make in two years if his pay remains constant?
Answer:
$69,600
Step-by-step explanation:
Figure out how much Ken makes a month by dividing 14500/5.
This gives you $2900.
If Ken makes $2900 a month and there are 24 months in two years, multiply his monthly earnings by 24 months.
$2900 * 24 = $69,600
Which best describes how to find an equation of the line shown?
A. The slope m is rise over run, so y over x =m. Solve for Y to get y=mx.
B. The slope m is run over rise, so x over y=m. Solve for x=ym.
C. The slope m is run over rise, so x over y=m. Solve for y to get y= x over m.
D. The slope m is rise over run, so x over y=m. Solve for x to get x=ym.
Answer:
AStep-by-step explanation:
m (slope) = rise = y = y₁ - y₁
run x x₁ - x₁
to get y = mx
therefore, the answer to the question is :
A. The slope m is rise over run, so y over x =m.
Solve for y to get y=mx.

Zoe and Maria plan to hike at a rate of 3 miles per hour and canoe at a rate of 6 miles per hour. They want to travel no more than 8 hours and cover at least 40 miles in one day. Which system of inequalities models the situation?
Answer:
h + c ≤ 8
3h + 6c ≥ 40
where h is the number of hiking hours
c is the number of canoeing hours
Step-by-step explanation:
Here, we want to write a system of inequalities;
Let number of hiking hours be h and the number of canoeing hours be c
h + c ≤ 8
Covering at least 40 miles;
Recall;
distance = speed * time
for 3 miles, h hours, we have 3h miles
for 6 miles , c hours , we have 6c
At least 40 miles, inequality will be ;
3h + 6c ≥ 40

Frank bought 4.3×10^4 yards of carpet to install in the new house. His wife said "We needed 5,000 yards! You didn't buy enough!"
Who is correct, Frank or his wife? Demonstrate with math to show your answer.
Answer:
Frank is correct.
Step-by-step explanation:
To convert 4.3 x [tex]10^{4}[/tex] into regular notation I move the decimal 4 places to the right and get 43,000. This is way more than enough for the 5,000 yards needed for the carpet. So, Frank's wife is wrong about it not being enough.
Answer:
The husband is correct. They needed 5,000, and he brought 43000.
Step-by-step explanation:
4.3*(10^4)=43000
