What value of z makes the equation true? 7/8=z/32 Answers: A. 7 B. 8 C. 14 D. 28

Answers

Answer 1
Answer: This is something you call "Proportions" or two ratios equal to each other.

(7)/(8)= (z)/(32)

Multiply 32 and 7.

(224)/(8) = z

The answer is z = (224)/(8) or 28
Answer 2
Answer: 7/8 of 32 is 28. Z is therefore d.) 28

Find the missing number.

32/52 = ?/13

Answers

Answer:  The required missing number is 8.

Step-by-step explanation:  We are given to find the missing number in the following proportion :

(32)/(52)=(?)/(13).

Let the missing number be represented by x.

Then, according to the given information, we have

(32)/(52)=(x)/(13)\n\n\n\Rightarrow (8)/(13)=(x)/(13)\n\n\n\Rightarrow x=(8)/(13)*13\n\n\Rightarrow x=8.

Thus, the required missing number is 8.

to get the third no add 5+2 =7 is the first digit of the 3rd no 
to get the second digit u need to find the difference between (addition of the digits of second no and addition of digits of the first no) i.e. (5+2)-(3+2)=7-5=2 
so the third no is 72 
similarly for the fourth no. 
first digit (7+4)=11 
second digit ((7+4)-(5+2))=11-7=4 
next no should be 114 
.... 
last number 135 
13+5 = 18 
The last digit is the difference between the last two answers, in this case, 18-13 = 5.

F(x)=x^3-3x^2-x+3

Factor each by grouping

Answers

Answer:

F(x) = (x - 3) (x + 1) (x - 1)

Step-by-step explanation:

F(x)=x³-3x²-x+3 = x² (x - 3) - (x - 3) = (x - 3) (x² - 1) = (x - 3) (x + 1) (x - 1)

Solve the equation. Select all that apply.x^2= 121
A
x = 11
B. x=21
C. X = 61
D. x=-11
E. X=-21

Answers

Answer:

x = 11, x = -11

Step-by-step explanation:

I know this is kind of late but the two previous answers were wrong.

We have x² = 121. To find x, we need to get rid of the exponent, and to do this, we can take the square root of both sides:

√x² = √121

x = √121

You might think that x = 11 but remember, x can be negative as well because you can square negative numbers. Basically, every real number has two square roots - a positive and a negative one. So, the answer isn't just x = 11, it's also x = -11 because (-11)² = 121 as well.

Answer:

x=11

A rectangle has an area of 30 square units and a perimeter of 34 meters.what are the dimensions of this rectangle

Answers

P=2L+2W
A=WL

Therefore, if P=34, and A=30, then let us find the factors of 30 that could give a sum of half of the perimeter which is 34. Therefore:

P=2*15+2*2
A=15*2

P=34
A=30

Therefore, the dimensions of this rectangle are 15 and 2.
