This triangle is a multiple of one of the triples listed here. What is the hypotenuse?

Answers

Answer:

50 units

Step-by-step explanation:

you use Pythagorean-theorem  which means A^2+B^2 =C^2

It does not matter the order of A and B because it is adding. But C is the hypotenuse.

If we plug in the # this is what it looks like...

14^2 +48^2=C^2

        or

48^2+14^2=C^2

14*14= 196

48*48=2,304

then you add

196+2,304=C^2

2,500= C^2

and you can use a calculator for this part you do 2,500

with the 2,500 you use the sign as in the picture and it gives you...

50

which means 50*50 = 2,500

50 units is the answer

the mass of a monarch butterfly is 0.56 g what is the mass of 4 monarch butterflies?

Answers

You multiply .56x4 or add .56 4 times. The mass of all 4 monarch butterflies is 2.24

The solution is: The mass of all 4 monarch butterflies is 2.24

Here, we have,

the mass of a monarch butterfly is 0.56 g,  we nee to find  the mass of 4 monarch butterflies

if 1 butterfly is 0.56 grams,

then 4 must be 0.56 x 4.

                        =2.24

we multiply .56x4 = 2.24

or add .56,  4 times.

i.e. .56 + .56 + .56 + .56 = 2.24

The mass of all 4 monarch butterflies is 2.24

we have worked out the answer :

0.56 x 4 = 2.24g

Hence, The solution is: The mass of all 4 monarch butterflies is 2.24

Use either the commutative property or combine like terms to create an equivalent expression
from the expression 9(2j + 5j).

Answers

Answer:

9(7j)/63j

Step-by-step explanation:

9(2j+5j)

= 9(7j)

= 63j

Okay so first you would want to mutiply 9 and 2 which gets you 18j the multiply 9 and 5 which gets you 45j then add like terms which in this case is 45j and 18j that will get you 63j and that’s your answer.

Which of the following sets shows all the numbers from the set {0, 0.5, 1, 2.5, 3} that make the inequality 2a + 3 ≥ 8 true?

{2.5, 3}
{1, 2.5, 3}
{0, 0.5, 1}
{0.5, 1}

Answers

Answer:

A

Step-by-step explanation:

it can't be any answer with 0, because when you substititue the variable a with 0, it simplifies to 3 ≥ 8 which is false, so C and D are incorrect. it also can't be B since when you substitue a with 1 it simplifies to 6 ≥ 8 which is also false. therefore A is the correct answer, hope this helps :)

Answer:

{2.5, 3}

Step-by-step explanation:

2a + 3 ≥ 8

2a + 3 - 3 ≥ 8 - 3

2a ≥ 5

[tex]\frac{2a}{2}[/tex] ≥ [tex]\frac{5}{2}[/tex]

a ≥ 2.5

From the expression above, a is equal to 2.5 and any number above 2.5

∴The answer is {2.5, 3}
