The answer is 210 because, first you take $400 and subtract 25%  and you get $300, then you take $300 and subtract 30% and you get the difference $210. So Sam sole the iphone for $210.

400-400*0.25=300

Question 1:

Look at the first attached image.

We want to solve for the height of the smaller building. Let's start by making a right triangle with angle of 15 degrees and adjacent side of 51 m.

Let's solve for the other leg. Multiply the tangent with 51 m to get the length of the other leg.

51*tan(15)
\approx 14

Now, subtract that from 207 to get the height of the smaller building.

207-14=193

That's your answer.

Question 2:

The angle of elevation is congruent to the angle of depression because they are alternate interior angles.

Thus, you can choose the 1st and 4th choices as your answer.

Question 3:

Look at the second attached image.

Angle E is congruent to angle D for the same reasons mentioned in the last question.
We can create an equation.

3x+1=2(x+8)

Distributive property

3x+1=2x+16

Subtract both sides by 1 and 2x

x=15

Since E and D are congruent, just plug this value into one of the equations for E or D. You get 46.

The third choice is your answer. Hope this helps! :)

The number of necklaces Lilly can make varies directly with the amount of time she spends making the necklaces. She can make 6 n
Fantom [35]

Answer:

75

Step-by-step explanation:

Number of necklace= k × amount of time spent

6= k × 2/5

K = 6÷2/5

K= 6×5/2

K= 15

Therefore the number of necklace made in 5 hours can be calculated as follows

15 = number of necklace ÷ 5

Number of necklace = 15 ×5

Number of necklace = 75

Point A is located at (−214,14). Point B is located at (234,14). What is the distance between point A and point B?
Sunny_sXe [5.5K]

Answer:

10, 14

Step-by-step explanation:

take the x values and plug into mid point formula and then divide by 2

so... (-214 + 234) divided by 2 = 10

do the same for the y values

so ... (14 + 14) divided by 2 = 14

so ... 10,14

What’s the measure of this angle
pashok25 [27]
First, write the expression.
180=(x+96)+5x
Second, add all coefficients.
180=6x+96
Subtract 96 from each side.
180-96=6x+96-96
84=6x
Divide both sides by 6.
14=x
Now that you have found the value of x, substitute x to solve the angles.
The first angle:
x+96
14+96=110 degrees
The second angle:
5*x
5*14=70 degrees
