Answer:

2 12/15 and 2 10/15

Step-by-step explanation:

4 x 3 = 12

2 x 5 = 10

Answer:

2 4/5=2 12/15

2 2/3=2 10/15

both with a common denominator of 15

hope this helps

have  a good day :)

Step-by-step explanation:

Answer:

<A = 120degrees

<B = 80degrees

<C = 60degrees

<D = 100degrees

Step-by-step explanation:

For a cyclic quadrilateral, the sum of the adjacent angle of the quadrilateral are equal, hence;

<A + <C = 180

<B + <D  = 180

Substitute the given values

4x+20+4y = 180

4x+4y =1 60

x + y = 40 ...1

Similarly;

3x+5+7y - 5 = 180

3x+7y = 180 ....2

Solving simultaneously

x + y = 40 ...1 .....* 3

3x+7y = 180 ....2 ...... *1

__________

3x + 3y = 120 ...1 .

3x+7y = 180 ....2

Subtract

3y - 7y = 120 - 180

-4y = -60

y = 15

Since x+y = 40

x + 15 = 40

x = 40 - 15

x = 25

<A = 4x+20

<A = 4(25)+20

<A = 120degrees

<C = 180 - <A

<C = 180 - 120

<C = 60degrees

<B = 3x+5

<B = 3(25)+5

<B = 80degrees

<D = 180 - <B

<D = 180 - 80

<D = 100degrees

Answer:

The answer is the photo

Step-by-step explanation:

To graph this, put the point on 3.

The equation is m < 3 which means m is less than 3 so the line goes to the left as whatever the number is, it would be on the left of 3.

Answer:

3:15:2 is the simplest form

Answer:

A: More than half of the scores were 85% or greater.

E: At least one score was exactly 85%

Step-by-step explanation:

Here the 5 test would be taken in science so 85% would be the result of one of the test

Also 85% represent the median so it means there are 2 values more and 2 values less

So there are 3 results with 85% or greater

Hence, the option A and Option E is correc

And, the rest of the options are wrong

Answer:

A and E

Step-by-step explanation:

Answer:

Yes and no solution :)

Step-by-step explanation:

No explanation needed for the first part.

2 as a fraction is 2/1

So rewrite as 2/1 + 2/1

We can multiply the whole equation by lets say.... 428

Now we have 856/428 + 856/428

Now we can put 0 at the other side of the equation... because... yes

856/428+856/428 = 0

Now lets just move one of these to the other side of the equation :)

856/428 = -856/428

Now I dont know, how about we cancel out the denominators.

856=-856

now if we move the right side back to the left... we get

1712=0

This equation is not true therefor 2+2 has no solution

Answer:

21,800

Step-by-step explanation:

Total costs is $16,700 x 4 years = 66,800

He saved 21,000 + receives 24,000 (6,000x4) grants for a total of 45,000 saved.

costs of 66,800 - receipts of 45,000 = 21,800 needed.

Step-by-step explanation:

Answer:

In the triangular prism calculator you can easily find out the volume of that solid. A general formula is volume = length * base_area; the one parameter you always need to have given is the prism length, and there are four ways to calculate the base - triangle area. Our triangular prism calculator has all of them implemented, isn't it awesome?

The specific formulas look as follows:

Length * Triangular base area given triangle base and height

It's this well-known formula mentioned before:

volume = length * 0.5 * b * h

Length * Triangular base area given three sides (SSS)

If you know the lengths of all sides, use the Heron's formula to find the area of triangular base:

volume = length * 0.25 * √( (a + b + c) * (-a + b + c) * (a - b + c) * (a + b - c) )

Length * Triangular base area given two sides and the angle between them (SAS)

You can calculate area of a triangle easily from trigonometry:

volume = length * 0.5 * a * b * sin(γ)

Length * Triangular base area given two angles and a side between them (ASA)

You can calculate that using trigonometry:

volume = = length * a² * sin(β) * sin(γ) / (2 * sin(β + γ))

Answer:

A and B (answer #2)

Step-by-step explanation:

right triangles: c^2 = a^2 + b^2

c is the largest side

for A: c = 5, a = 3, b = 4

5^2 = 3^2 + 4^2

25 = 25, so A is a right triangle

for B, c = 13, a = 5, b = 12

13^2 = 5^2 + 12^2

169 = 169, so B is a right triangle

for C, c = 4, a = 2, b = 3

4^2 = 2^2 + 3^2

16 ≠ 13, so C is not a right triangle

So, A and B are right triangles.
