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.

Step-by-step explanation:

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

now let's get the measurements of the angles

13(2) + 12= 38

20(2) + 12= 52

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.

Answer:

B bro

Step-by-step explanation:

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.

Answer:

4

Step-by-step explanation:

This question can be solved by proportions, using rule of three.

We have that:

You buy 78 peaches for $77.95. How much you pay to buy 4 peaches?

78 peaches - $77.95

4 peaches - x

[tex]78x = 4*77.95[/tex]

[tex]x = \frac{4*77.95}{78}[/tex]

[tex]x = 4[/tex]

You pay $4 for 4 peaches.

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.
