Mathematics
1 answer:
balandron [24]3 years ago

Answer:

27

Step-by-step explanation:

Area of Triangle x 2 = 3 * 3

The reason I did not divide it by 2 is because of how the other triangle is bound to have the same area. Just leave it as it is because later you're going to reach the same answer.

3 * 3 = 9

Rectangle Area = 6 * 3 = 18

18 + 9 = 27

VARVARA [1.3K]

Answer:

A) 9^7

Step-by-step explanation:

For this type of problem, since they both have the same base, you can add the exponents together and have the base remain the same. So you would have 5+2 = 7.

Use the Pythagorean theorem to find the length of the diagonal of a square that has an area of 289 square inches
Veronika [31]

Answer:

The answer is approximately 24.041 inches (round to the nearest tenth, hundredth, or thousandth if it is indicated in the instructions.)

Step-by-step explanation:

First, I figured out what the square root of 289 is. The square root of 289 is 17.

Given that this is a square we are dealing with, we can assume that all sides are equal.

So, when you draw a diagonal down the square, it becomes two triangles, one of which we can use the Pythagorean theorem for.

a^2 + b^2 = c^2. Thus, 17^2 + 17^2 = 578. The square root of 578 unfortunately does not come out evenly, so we are left with approximately 24.041 inches.

I hope this helps!

What is the equation of aline that passes through the point (4,-8) and has a slope of -1/2?
viktelen [127]

Answer:

The equation of the line will be:

y=-\frac{1}{2}x-6

Step-by-step explanation:

Given

  • slope = m = -1/2
  • point (4, -8)

Point slope form:

y-y_1=m\left(x-x_1\right)

substituting the values m = -1/2 and the point (4,-8)

y-\left(-8\right)=\frac{-1}{2}\left(x-4\right)

y+8=\frac{-1}{2}\left(x-4\right)

subtract 8 from both sides

y+8-8=\frac{-1}{2}\left(x-4\right)-8

y=-\frac{1}{2}x-6

Therefore, the equation of the line will be:

y=-\frac{1}{2}x-6

Q# 7 please anybody help me
astra-53 [7]

√42 is an irrational number, because you cannot express the answer as a fraction (ratio), and it certainly isn't a whole number or an integer.
