Monica uses the distributive property to write and equivalent expression to 63+28. Which expression did Monica write?A. 9(7+3)
B. 3(21+25)
C. 7(9+4)
D. 3(60+25)

Answers

Answer 1
Answer:

The correct option is c, which is 7(9+4).

The distributive property is a property that helps us to know that when a number is multiplied by the sum of two numbers, it is equal to the sum of products of these two numbersmultiplied by the third number individually.

For example,

a(b+c) = ab+ac,

Now, as given Monica uses the distributive property to write an equivalent expression to 63+28.

therefore, the common ratio is 63, and 28 is 7.

Thus, 63+28 = 7(9+4).

Thus, the correct option is c, which is 7(9+4).

Answer 2
Answer:

Answer:

C

Step-by-step explanation:

The highest common factor of 63 and 28 is 7, thus taking out 7 gives

63 + 28 = 7(9 + 4) → C

Really really need help A six-sided number cube is rolled. Find the probability of rolling a 3 or a number greater than 4.

A.1/8
B.1/6
C.1/2
D.2/3

Answers


Well, there are 6 sides.

There are also 6 numbers: 1, 2, 3, 4, 5, 6

Okay, so the probability of rolling a 3 is 1/6 because that is just one number of the 6.

Okay, number greater than four are 5 and 6, and if you add 3 to that you get 3/6, or 3 out of 6 numbers.

If you simplify 3/6 you get 1/2.

Hope this helps!
There are 6 sides and numbers in the cube. (1,2,3,4,5,6)
Probability of rolling a 3 or a number greater than 4: there are 2 numbers greater than 4 (5 and 6) and one other number (3). In total, there are 3 numbers here.

So the probability of rolling 3 numbers out of 6 is 3/6, which can be simplified to 1/2.

What is the greatest common factor of 65 and 91

Answers

So,

First, we find the prime factored form (P.F.F.) of 65 and 91.

P.F.F. of 65: 5 * 13

P.F.F. of 91: 7 * 13

Find the common numbers
13

13 = G.C.F.

Note: This method works for finding any G.C.F. (find common primes)

The greatest common factor (GCF) of 65 and 91 is 13 by using prime factorization method:

To find the GCF of two numbers,  to determine the largest number that divides both of them evenly.

To find the GCF of 65 and 91,  use the prime factorization method:

Step 1: Prime factorize both numbers:

65 = 5 × 13

91 = 7 × 13

Step 2: Identify the common prime factors:

Both 65 and 91 share the prime factor 13.

Step 3: Determine the highest common prime factor:

The highest common prime factor of 65 and 91 is 13.

Therefore, the GCF of 65 and 91 is 13.

Which number is between 0.5 and 5/8 A.1/4 B.8/28 C.9/16 D.19/25

Answers

try doing a number line :

0.5____________________________0_________________________5/8 

so then you need to convert 0.5 into a fraction so it looks like this :

0.5 is equal to 5/10 then you simplify 5/10 :

5 can go into 5 once so that's   1 
and  
5 can go into 10 twice so that's 2 

so you just simplify 5/10 into 1/2 
so your number line should now look something like this:

5/8_________________________________________________________1/2 

then you can convert your fractions into percents 

A.1/4 is 25%
B.8/28 is 28.5%  (not sure)
C.9/16 is 56%     (not sure )
D. 19/25 is 76%

then you convert your numbers on your numbers line so that would be the fractions 5/8 and 1/2 

5/8 is 63%
1/2 is 50%

put them on a number line like this 

50%_______________________________________63% 

and your answers 
A.25%
B.28.5%
C.56%
D.76%

** Now you can easily scratch A. B. and D. because there either too high or too low  !!!

And the Answer is C. 56% or in the original question it would be C. 9/16 

In a 45-45-90 triangle, what is the length of the hypotenuse when the length of one of the legs is 11 in.?

Answers

Answer:

= 15.556 in

Step-by-step explanation:

Since this is a 45-45-90 triangle, we can tell that;

  • This is a right triangle  
  • This is an isosceles triangle

One of the theorems of geometry, the Isosceles Right Triangle Theorem, says that the hypotenuse is √2 times the length of a leg.

Therefore;

hypotenuse = leg × √2

If we take hypotenuse as x

Since the leg is 11;

Then; x = 11√2

x = 11/√2

x = 15.556 in
