Superman needs to save Lois from the clutches of Lex Luthor. After flying for 8 seconds, he is 1692
meters from her. Then at 16 seconds he is 1284 meters from her.
How close to Lois is Superman after 29 seconds?

Answers

1692-1284 = 408 meters travelled in 8 seconds

408/8 = 51 meters per second is his rate of speed.

51 x 29 = 1479 meters

BUT he was 1284 meters away, so by traveling 1479 meters, he passed her.

1479 - 1284 = 195 meters past her.

He is 195 meters away from Lois at 29 seconds.

Now we could argue, since Superman is not a fool, he would’ve stopped at Lois. But that’s not what your math teacher is looking for ;)

Answers

Answer:

The answer is B

Step-by-step explanation:

Since parallelograms have a total of 360 degrees, you just have to add the 115 and 64 to get 179. The 124 is completely irrevant in this entire problem. So then 360-179=181. It is B because y is an acute angle, meaning that the value HAS to be under 90 degrees, and only B has y as an acute angle measurement.

Explain the importance of using the square of the scale factor to calculate the area of a dilated figure

Answers

Answer:

2

Step-by-step explanation:

2+2=4 therefore 2x2 also equals 4, 4/2=2.

In mathematics and geometry, a dilation is an enlargement in size or a reduction in size of a mathematical object. We perform a dilation of a square by placing the shape on a coordinate plane and multiplying each of the coordinates of the vertices of the square by the same number, called the scale factor. This can also be achieved by multiplying the lengths of each of the sides of a square by the scale factor.

When we dilate a square by a scale factor of k, its sides increase by a factor of k, its area by [tex]k^{2}[/tex], and its volume by [tex]k^{3}[/tex].

So, this is the importance of using the square of the scale factor to calculate the area of a dilated figure.

What is Square?

Square, in geometry, a plane figure with four equal sides and four right (90°) angles. A square is a special kind of rectangle (an equilateral one) and a special kind of parallelogram (an equilateral and equiangular one).

What is scale factor?

The scale factor is a measure for similar figures, who look the same but have different scales or measures. Suppose, two circle looks similar but they could have varying radii. The scale factor states the scale by which a figure is bigger or smaller than the original figure.

Mary is planning to buy a mobile phone that costs $500. A salesperson at the store informs her about four different installment plans that she can choose from.

plan A: a down payment of $50 and monthly payments of $40 for 12 months
plan B: a down payment of $100 and monthly payments of $80 for 6 months
plan C: no down payment and monthly payments of $60 for 12 months
plan D: no down payment and monthly payments of $100 for 6 months

Which plan will have the highest finance charge?

Answers

Step-by-step explanation:

plan A

40 x 12 = 480 + 50 = 530

plan B

80 x 6 = 480 + 100 =580

plan c

60 x 12 = 720 no down payment

plan d

100 x 6 = 600 no down payment

so the highest finance charge will be plan c although it doesn't have down payment but the $60 charge every month for 12 months will estimate you the amount of $720

Is the following statement true? Explain.

" For any two angles A and B, cos (A+B)=cos (A)+cos (B) "

Answers

Step-by-step explanation:

We can prove the statement is false by proof of contradiction:

We know that cos0° = 1 and cos90° = 0.

Let A = 0° and B = 90°.

Left-Hand Side:

cos(A + B) = cos(0° + 90°) = cos90° = 0.

Right-Hand Side:

cos(A) + cos(B) = cos(0°) + cos(90°)

= 1 + 0 = 1.

Since LHS =/= RHS, by proof of contradiction,

the statement is false.

The measures of two complementary angles are described by the expression(13y+12) and (20y+12). Find the measures of angles​

Step-by-step explanation:

complementary angles means that both of them together = 90

13y +12 + 20y + 12 = 90

add all y together and numbers together

33y + 24 = 90

solve for y

33y= 66. y= 2

A line has a slope of -1/10
and includes the points (1, -6) and (t, -5). What is the value of t?

Answers

Answer:

-9

Step-by-step explanation:

Here we use the slope formula: m= y2-y1/x2-x1. We simply plug in the numbers we know: -1/10 = -5+6/t-1. Then we solve for t. Multiply both sides by (t-1) so -1/10 (t-1)= 1. Then multiply both sides by -1/10 so t-1= -10 and then add one to both sides so t=-9.
