Answer:

The answer would be 22/12 or 1 and 11/12

Step-by-step explanation:

1/2+2/3+3/4

First get common denominators so you have a denominator of 12 so 6/12+8/12+9/12

Add those together and you get 23/12 but you have to subtract one because that's what the problem says so you get 22/12

Option D

The prime factorization of 50 is $2 \times 5^2$

Solution:

Given that, we have to find prime factorization of 50

The prime factorization is any of the prime numbers that can be multiplied to give the original number

Prime Factorization of 50

Step 1: Start by dividing the number by the first prime number 2 and continue dividing by 2 until you get a decimal or remainder

$50 \div 2 = 25$

Then divide by 3, 5, 7, etc. until the only numbers left are prime numbers

$25 \div 5 = 5\\\\5 \div 5 = 1$

Step 2: Write the number as a product of prime numbers

$\text{ Prime factorization of 50 } = 2 \times 5 \times 5$

In exponential form,

$\text{Prime factorization of 50 } = 2 \times 5^2$

Thus option D is correct

Is triangle XYZ = ABC ? If so, name the postulate that applies. A. Congruent - ASA B. Congruent - SAS C. Might not be congruent

vivado [14]

The answer is the SAS postulate. The two triangles have two pairs of corresponding, congruent sides, and the included angles are congruent. And thus, triangles XYZ and ABC are congruent by the SAS postulate.

What is the sum of the geometric sequence −4, 24, −144, ... if there are 8 terms?

Helga [31]

Answer:

The sum of 8 geometric sequence is 959780

Step-by-step explanation:

We are given

this sequence is geometric

-4 , 24 , -144

First term is -4

so, $a_1=-4$

now, we can find common ratio

$r=\frac{24}{-4}=-6$

we can use formula

$S_n=a_1(\frac{1-r^n}{1-r} )$

n=8

now, we can plug values

$S_8=-4(\frac{1-(-6)^{8}}{1+6} )$

now, we can simplify it

and we get

$S_8=959780$
