Step 1: m2m+mZn +mzo = 180 degrees (sum of angles of a triangle)
Step 2: mp +mZo = 180 degrees (adjacent supplementary angles)
Step 3: Therefore, mZm+mZn+mZo=mZn + MZD Step 4: So.mZm+mZn=mZp
In which step did the student first make a mistake and how can i be corrected?
Step 1: it should be mZm+mZnam 2990 degrees (corresponding angles)
Step 1: I should be mm +mZn+mZo = 90 degrees (adjacent angles)
Step 3: t should be mZm+mZnm Zo=mZo-mZp Step 2. n should be mZo-mZo=90 degrees (complementary angles) -​

Answer :SOLVING EQUATIONS CONTAINING ABSOLUTE VALUE(S)

Step 1: Isolate the absolute value expression.

Step2: Set the quantity inside the absolute value notation equal to + and - the quantity on the other side of the equation.

Step 3: Solve for the unknown in both equations.

Step 4: Check your answer analytically or graphically.

Step-by-step explanation:

Answer:

x can equal 5 or -5 since absolute value changes everything into a positive number.

Answer:Answer Expert Verified. The Answer is that the present value of $100 is $100. Because this $100 dollar is deposited today so the time is equal to zero and when time is zero the value of amount is the value of amount itself.

Answer:

Plug g(x) into all the x values in your f(x) and the answer is 3 because it makes the denominator 1-1 which makes it 0 and is thus discontinuous

Answer:

Option (4)

Step-by-step explanation:

[tex]m(\widehat{FC})[/tex] = 180° [FC is the diameter]

[tex]m(\widehat{FC})=m(\widehat{FB})+m(\widehat{BC})[/tex]

180° = 125° + [tex]m(\widehat{BC})[/tex]

[tex]m(\widehat{BC})=180-125[/tex] = 55°

[tex]m(\widehat{FBD})=360-m(\widehat{FED})[/tex]

               [tex]=360-[m(\widehat{FE})+m(\widehat{ED})][/tex]

               [tex]=360-[m(\widehat{BC})+m(\widehat{ED})][/tex] [Since [tex]m(\widehat{FE})=m(\widehat{BC})[/tex] arcs created by vertical angles]

               [tex]=360-(55+56)[/tex]

               = 249°

Therefore, Option (4) will be the answer.

Answer:

Answer: (a) = b,  49/64

Step-by-step explanation:

Answer:

x = 11/c

Step-by-step explanation:

Solve for x:

c x - 4 = 7

Hint: | Isolate terms with x to the left-hand side.

Add 4 to both sides:

c x = 11

Hint: | Solve for x.

Divide both sides by c:

Answer: x = 11/c

Answer:

The equation in slope-intercept form would be y=1x+1

Step-by-step explanation:

We can use the slope formula,

m=y2-y1/x2-x1

m=7-5/6-4

m=1

plug in m for y intercept or "b" and choose either points to sub. for the x & y

I am going to choose the (6,7)

7=6(1)+b

7-6=6-6+b

b=1

Our "b" is equal to 1 and just add in the points to the slope formula y=mx+b

Answer:244

Step-by-step explanation:

Well first I took 7 and 12 multiplied them to get 84 and the added 32 by 5 by multiplying them, To 84 and these are averages so they aren’t exacts and it gave me 244

Answer:

244

Step-by-step explanation:

12+12+12+12+12+12+12=

24+24+24+12=

48+36= 84

32+32+32+32+32=

64+64+32=

128+32= 160

160+84=244

or

12*7= 84

32*5= 160

160+84=244

Answer:

[tex]t=-48[/tex]

Step-by-step explanation:

We have the function:

[tex]d(t)=\frac{t}{2}[/tex]

And we want to find t when:

[tex]d(t)=-24[/tex]

So, let's substitute -24 for our first equation and solve for t:

[tex]-24=\frac{t}{2}[/tex]

Multiply both sides by 2:

[tex]t=-48[/tex]

So, the value of t when d(t)=-24 is -48.

Answer:

No an irrational number

Step-by-step explanation:

An irrational number is a number that cannot be expressed as a fraction of two integers . -1.36 can be expresed as -136/100

Answer:

Rational!

Step-by-step explanation:

Any number that can be written in fraction form is a rational number. This includes integers, terminating decimals, and repeating decimals as well as fractions. So, any terminating decimal is a rational number. Any decimal number that is repeating can be written in the form a/b with b not equal to zero so it is a rational number.

I hope this helps you understand what a rational number is! Have a wonderful day!

Answer:

2/5

Step-by-step explanation:

f(x) = 4/5 x - 2

Let x=3

f(3) = 4/5 *3 - 2

     =12/5 -2

    =12/5 -10/5

    = 2/5

Answer:

B (same slope, lower starting point)

Step-by-step explanation:

The slope on this graph is 5, and the slope of y=5x+5 is 5, so the slopes are the same.

This graph has a y-intercept of -6, which is lower than y=5x+5's intercept of 5, so it starts lower, so B.

Answer:

40%

Step-by-step explanation:

Every week you he buys 4 number of 2 Litres bottle of lemonade.

Thus, let's say cost of each bottle is X.

This means he total cost is 4X

Now, total litres = 4 × 2 = 8 litres

Thus, cost per litre = 4X/8 = ½X

Now, we are told that Last week the bottles on the shelf were limited edition “2.5 litres for the price of 2 litres” bottles ".

This means that now, it is cheaper.

However, the supermarket also had a “buy 3 bottles, get another one free” offer.

Now since he buys 8 litres weekly, now since it's 2.5 L bottle, he will buy 3 since he will be given 1 free for every 3 he buys.

Thus, total litres he is paying for = 2.5 × 3 = 7.5 litres

Thus, cost per bottle is; 3X

Since he is getting 1 bottle free, then total bottle he gets is; 7.5 L + 2.5 L = 10L

Thus;

cost per litre is now; 3X/10

Difference in costs per litre is;

½X - 3X/10 = X/5

percentage of the cost of four bottles of lemonade lower than usual last week = (X/5)/(½X) × 100% = 2/5 × 100% = 40%
