Answer/Step-by-step explanation:


If your question has different numbers and options but its the same pretty much the answer is square root of 85

If your question is this the answer is square root of 45

Explained below;


For the one with different option choices but the answer square root of 85 is visible the answer is square root of 85, for people with these option choices the answer 3√5 or 6.7082039324994, rounded that would be 7. Square root of 49 = 7. So the possible answer choice for this is square root of 49 if thats an option choice. If 49 is not an option choice then the answer could be square root of 45. Because square root of 45 = 6.7082039324994 which is what we had before we rounded. The question doesn't say to round so its most likely square root of 45.

Answer: 90 seconds or 1.5 minutes

Step-by-step explanation: 2 minutes(120 seconds) divided by 4 edges equals 30 seconds per edge. To get from 1 corner to the diagonally opposed opposite corner the fly would walk on 3 edges, so it would take 90 seconds

The time taken to cross from one corner to another diagonally is 90 seconds or 1.5 minutes.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that a fly can walk around a cubical block in two minutes.

The time taken to cover all the one edge is,

T = 120 / 4

T = 30 seconds

To get from 1 corner to the diagonally opposed opposite corner the fly would walk on 3 edges, so it would take 90 seconds. Mathematically written as,

To = 3 x 30

To = 90 seconds

To = 1.5 minutes

Therefore, the time taken to cross from one corner to another diagonally is 90 seconds or 1.5 minutes.

Answer:

50=(3x)x

Step-by-step explanation:

50=(3x)x. The question is only asking for the inequality of the problem. Since the area of a rectangle is L x W, you would write L as 3x and W as x, and since the area of the rectangle is given, you can set the area as 50.

The set of side lengths which does not form a right triangle is 9m, 11m, 13m

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the measure of sides of the triangle are

AB = 9 m

BC = 11 m

AC = 13 m

Now , for a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

AC² = AB² + BC²

On simplifying , we get

13² = 9² + 11²

169 ≠ 81 + 121

Hence , the sides 9m, 11m, 13m does not form a right triangle

Answer:

156

Step-by-step explanation:

Let measure of angle C = x.

Then, the measure of angle B is 14x.

14x + x = 180

15x = 180

x = 12

14x = 14(12) = 168

168 - 12 = 156

Explanation:

The angles marked are corresponding angles, since they correspond in the same direction. Both are pointing to the southwest direction.

Since line DE is parallel to line FG, this means the corresponding angles mentioned are congruent.

Set them equal to each other and solve for x.

7x+18 = 81

Answer:

B

Step-by-step explanation:

A is just moving the shape left

C is flipping the shape the opposite direction

B rotated the shape

If you mean, Rotating the whole square, then yes. The answer is "B"

BUT! If you mean rotating the triangle in it-self, THEN the real answer is "C"!

Answer:

b

Step-by-step explanation:

You have to solve all the equations to find which one equals 8

For a, you can take away the zero which leaves you with 72/9 which is 8. Then you add the zero back to the answer which gives you 80.

For b, you can cancel out the zeroes from 720 and 90 which gives you 72/9 again. That leaves you with 8.

For c, take away the zeroes leaving you with 72/9. Then you have 800 when you add the zeroes back.

For d, you can cancel out one of the zeroes which will give you 720/9. Then you take away the zero and now you have 72/9 again. Then add the zero to the answer which will give you 80.

Because b is the only equation that equals 8, it must be the answer.

Answer:

12 ÷(2 + 2/3) ^2 = 27/16= 1 11/16 = 1.6875

Step-by-step explanation:

Add: 2 + 2/3= 2/1 + 2/3 = 2 · 3/1 · 3+ 2/3 = 6/3 + 2/3 = 6 + 2/ = 8/3                    It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - is LCM(1, 3) = 3. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 1 × 3 = 3. In the following intermediate step, it cannot further simplify the fraction result by canceling. In other words - two plus two-thirds is eight-thirds. Exponentiation: the result of step No. 1 ^ 2 = 8/3 ^ 2 = 82/32 = 64/9 In other words - eight-thirds raised to the power of squared is sixty-four-ninths. Divide: 12 : the result of step No. 2 = 12 : 64/9 = 12/1 · 9/64= 12 · 9/1 6= 108/64 = 4 · 27/4 · 16 = 27/16. Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 64/9 is 9/ 64) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the following intermediate step, cancel by a common factor of 4 gives 27/16. In other words - twelve divided by sixty-four ninths is twenty-seven sixteenths.
