Step-by-step explanation:

Answer:

Triangle B

Step-by-step explanation:

For a triangle with sides a, b and c,

If c² = a² + b²

Then triangle will be a right triangle.

If c² > a² + b²

Triangle will be an obtuse triangle

If c² < a² + b²

Triangle will be an acute triangle.

By applying these properties in the given triangles,

Triangle A:

6 cm, 8 cm and 10 cm

6² + 8² = 36 + 64

6² + 8² = 100 [c² = a² + b²]

Therefore, it's a right triangle.

Triangle B:

310 in, 25 in and 35 in

25² + 35² = 625 + 1225

                = 1850

Since, 310² = 96100

And 96100 > 1850 [c² > a² + b²]

Therefore, It's an obtuse triangle.          

Triangle C:

8 ft, 15 ft and 35 ft

8² + 15² = 64 + 225

             = 289

Since, 17² = 289 [c² = a² + b²]

Therefore, It's a right triangle.

Triangle D:

0.32 mm, 0.96 mm and 1 mm

(0.32)² + (0.96)² = 1.024

Since, 1² = 1

And 1 < 1.024 [c² < a² + b²]

Therefore, triangle will be an acute triangle.

Answer:

Step-by-step explanation:

Given

Let's see what relationship has the function g(x) and f(x):

As we see the function g(x) is the translation of the function f(x) up by one unit

Note: there is one transformation as described above. The interim steps in the solution could possibly be considered as different ways (like two units up and one unit down). The final position is just one way translation.

Answer:

-14

Step-by-step explanation:

Since x is negative, the median of the set is 14. Therefore, the mean of the set is 14 + 5 = 19, and its sum is 19 · 5 = 95. Since 12, 38, 45, and 14 sum to 109, the remaining integer x must be 95 − 109 = −14 .

Answer:

Step-by-step explanation:

Given set of numbers:

Put them in ascending order, considering the x is negative

The median is 14

The mean is 5 greater than median:

The mean is calculated:

Answer:

A) y ≥ -4

Step-by-step explanation:

The range of a function basically represents all of the y values that a function encompasses (I hope that makes sense, if not, please let me know).

In this graph, since the parabola has a vertex at (1, -4), the range includes y values only greater than or equal to -4. The function does not include y values lower than -4. Therefore, the range must be y ≥ -4.

Answer:

I think it should be 2 triangle

If it get wrong , so sorry for wrong answer

Answer:

the 2nd one

Step-by-step explanation:

=======================================================

Explanation:

The first number along the top is 40, and it multiplies with the second number along the side to get 40 x 5 = 200

You can think of it as 4 x 5 = 20, then you tack on an extra 0 to the '4' and to the '2' as well, so it keeps things balanced.

So this explains how choice D is one of the answers.

-------------------------

After 200 fills in that question mark, we'll have these four numbers inside the table: 2400, 420, 200, and 35

Those four values add up to: 2400+420+200+35 = 3055

This shows that choice A is one of the answers.

--------------------------

Finally, choice E is the third answer because along the top we have 40+7 = 47, and along the side we have 60+5 = 65

Put another way, the total top length is the sum of the two smaller pieces of 40 and 7, which explains how the total top length is 47 units long. A similar argument happens for the left side values as well.

We ultimately have a rectangle that is 47 units across in the horizontal direction, and 65 units tall in the vertical direction.

With your calculator, you should note that 47*65 = 3055 to help confirm everything lines up.

--------------------------

Extra info:

Choice B is false because this contradicts choice D.

Choice C is false because it contradicts choice E

Answer:

60%

Step-by-step explanation:

Just divide 15 by 25 and then move the decimal point 2 places to the right. Then turn that number into a percentage.

Answer:

The answer is 60%

Step-by-step explanation:

You could check it by using a calculator, just enter 25x60%= 15

Answer:

Simplifying

10x + -5(3x + -1) = 15

Reorder the terms:

10x + -5(-1 + 3x) = 15

10x + (-1 * -5 + 3x * -5) = 15

10x + (5 + -15x) = 15

Reorder the terms:

5 + 10x + -15x = 15

Combine like terms: 10x + -15x = -5x

5 + -5x = 15

Solving

5 + -5x = 15

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5' to each side of the equation.

5 + -5 + -5x = 15 + -5

Combine like terms: 5 + -5 = 0

0 + -5x = 15 + -5

-5x = 15 + -5

Combine like terms: 15 + -5 = 10

-5x = 10

Divide each side by '-5'.

x = -2

Simplifying

x = -2

Answer: 8.25cm

Step-by-step explanation:

Use Pythagorean's Theorem for a right triangle:

[tex]a^2+b^2=c^2[/tex]

'A' and 'B' being the legs and 'C' being the hypotenuse.

[tex]16^2+b^2=18^2\\256+b^2=324\\b^2=68\\b=\sqrt{68}=8.25cm[/tex]

Answer:

47

Step-by-step explanation:

Angles B and D are equal.

Angles A and C are equal.

Anges in parallelogram add up to 360°

5x+38=8x-19

57=3x

x=19

B=(5×19)+38=133°

D=(8×19)-19=133°

A+C=360-133-133

A+C=94

A and C are the same so you can do 94/2=

Therefore, both angles A and C are 47 :D

The measure of angle c in the parallelogram is 47°.

A parallelogram is a quadrilateral (has four sides and four angles) in which opposite sides are parallel and equal. Also, opposite angles are equal and the shape has equal diagonals.

∠B = ∠D (opposite angles are equal)

8x - 19 = 5x + 38

x = 19

∠B = 5(19) + 38 = 133°

∠C + ∠B  = 180° (base angles of parallelogram_

∠C + 133 = 180

∠C = 47°

The measure of angle c in the parallelogram is 47°.

Answer:

Step-by-step explanation:

round it if you have to

Answer:

75 cm

Step-by-step explanation:

The diagonal d divides the rectangle into 2 right triangles with d as the hypotenuse.

Using the right triangle formed on the left and using Pythagoras' identity.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

d² = 45² + 60² = 2025 + 3600 = 5625 ( take square root of both sides )

d = 75

The diagonal is 75 cm

Answer:

The two numbers are 12 and 30

Step-by-step explanation:

It is given that both the numbers are greater than 6

Let the two numbers be X and Y

As we know

X * Y = LCM * HCF

XY = 360

Let us list down some combinations of X and Y and test above conditions

There can be following pairs

a) 6,60

b) 18,20

c) 24,15

d) 12,30

LCM of the two numbers is 60 and both the numbers are greater than 6

So only 12, 30 satisfy the set condition.

Answer: Chris is taller by 5 inches.

Step-by-step explanation:

You need to convert one of them to the other's unit of measurement so as to be able to measure effectively.

Assuming we convert to inches.

An inch is 2.54 cm.

Since Chris is 185 cm tall, Chris's height in inches is:

= 185 / 2.4

= 77 inches

Chris is therefore taller by 5 inches.

ok so i really shouldnt get points for this, but i wanted to help. The person who solved the problem here:  https://math.stackexchange.com/questions/2911546/suppose-the-sides-of-a-triangle-form-a-geometric-progression-with-common-ratio-r     is correct, but it is not very clear. Basically, he rounded to the third decimal point (since a sqrt has infinate decimals), and this might have been what got you the wrong answer. Basically the important thing is that r has to be between the (-1+√5)/2 and (1+√5)/2, or (-1+√5)/2 < r < (-1+√5)/2
