Can anyone pls help me with this ?

Answer:

In mathematics, to solve an equation is to find its solutions, which are the values (numbers, functions, sets, etc.) that fulfill the condition stated by the equation, consisting generally of two expressions related by an equals sign. When seeking a solution, one or more variables are designated as unknowns.

Answer:

31) They divided by 100, they're suppose to times 0.86 by 100 instead, which will be 86%

33) 0.34 x 100=34%

35) we do the inverse to turn it back into

a decimal which will be 0.36

[tex] \frac{36}{100} = \frac{18}{50} = \frac{9}{25} [/tex]

36) 16.24÷100=0.6424

[tex] \frac{16.24}{100} = \frac{8.12}{50} = \frac{4.6}{25} [/tex]

Answer: c = [tex]\sqrt{89}[/tex]

8² + 5² = c²

64 + 25 = c²

[tex]\sqrt{89}[/tex] = [tex]\sqrt{c^{2} }[/tex]

[tex]\sqrt{89}[/tex] = c

The length of the third side is 9.4.

Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We have,

Applying Pythagorean theorem.

Third side = x

x² = 8² + 5²

8 x 8 = 64 and 5 x 5 = 25

So,

x² = 64 + 25

x² = 89

x = √89
x = 9.4333

Rounding to the nearest tenth

x = 9.4

Thus,

The length of the third side is 9.4.

Answer: 1 5/6

Step-by-step explanation:

From the question given, we are told that out of some shapes shown, 1/3 of the shapes are circles and 1 1/2 are rectangles.

The fraction of the shapes that are either circles or rectangles, will be gotten by adding the shapes that are circle to those that are rectangle. This will be:

= 1/3 + 1 1/2

We should make the fraction have a common denominator.

= 2/6 + 1 3/6

= 1 5/6

The answer is 1 5/6.

Answer:

55 cm²

Step-by-step explanation:

side length of square = perimeter/4 = 40/4 = 10 cm.

area of square = side x side = 10 x 10 = 100 cm²

area of triangle #1 = 1/2bh = 1/2(3)(10) = 15

area of triangle #2 = 1/2bh = 1/2(6)(10) = 30

100 - 15 - 30 = 55 cm²

Answer: 18 miles.

Step-by-step explanation:

We can think on this as a triangle rectangle, where one cathetus is 12miles, and the other cathetus is 5 miles. (so the vertex of the triangle rectangle are Annie's house, the school, and the store)

The path that Annie would do is:

From her house to the store (so she drives 5 miles)

And from the store to the school, so here she drives through the hypotenuse of the triangle rectangle.

Then we need to find the length of this triangle rectangle.

We know that the square of the hypotenuse is equal to the sum of the squares of the cathetus, then:

H^2 = (12mi)^2 + (5mi)^2

H = √( (12mi)^2 + (5mi)^2) = 13mi

Then she first drives 5 miles from her house to the store, and then drives 13 miles from the store to the school, then the total distance that she drives is:

5 miles + 13 miles = 18 miles.

Answer:

  2x -1

Step-by-step explanation:

The perimeter is the sum of the side lengths.

  P = 6 + (x -4) + (x -3)

  P = 2x -1 . . . . . . collect terms

The perimeter is 2x -1.

Additional comment

There is nothing in the problem statement that suggests this is a right triangle. Without knowing at least one angle, we cannot solve for a numerical value for the perimeter. The problem title suggests we're to leave the result in polynomial form.
