Answer 1
Answer:

Answer:

The last choice is correct

LCM=120a^4b^7c^5

Step-by-step explanation:

Least Common Multiple (LCM)

To find the LCM we can follow this procedure:

List the prime factors of each monomial.

Multiply each factor the greatest number of times it occurs in either factor.

We have two monomials:

12a^4b^2c^5

40a^3b^7c^1

The prime factors of the first monomial are:

2^2,3,a^4,b^2,c^5

The prime factors of the second monomial are:

2^3,5,a^3b^7c^1

LCM = Multiply 2^3*3*5*a^4*b^7*c^5

These are all the factors the greatest number of times they occur.

Operating:

LCM=8*15*a^4*b^7*c^5

\boxed{LCM=120a^4b^7c^5}

The last choice is correct

Which one of the following mathematical statements is true?A. 28 + 0 = 0
B. 0 ÷ 28 = 0
C. 28 – 0 = 0
D. 28 ÷ 0 = 0

Answers

B. 0 ÷ 28 = 0

Is the mathematical statement that is true.

Rule of ZERO. Zero(0) can be a numerator with non-zero denominator. Its overall value is equal to 0.

Rule of ZERO. A fraction with a denominator of ZERO is not a legal fraction. This is because the overall value of a number divided by zero is undefined.

28 + 0 = 28 not 0.
28 - 0 = 28 not 0.
28 ÷ 0 = ERROR! not 0. value is undefined

13x+8+8x=-9x-22

please help i’m so confused

Answers

Answer:

-1

Step-by-step explanation:

-isolate everything  with x on one side and without x on the other side

-remember if you pass the equal sign change the sign of that term

13x+8x+9x = -22-8

-combine like terms

30x = -30

-divide both sides by 30

x= -1

Answer:

x = -1

Step-by-step explanation:

simplfy to 21x + 8 = -9x -22

add 9x  to get 30x + 8 = -22

then subtract 8 to get 30x =-30

divide by 30 and you get x = -1

use the given conditions to write an equation for the line in point slope form passing through (-5,7) and (-8,6)

Answers

point slope form is
y-y1=m(x-x1)
where slope=m
and (x1,y1) is a given point

slope=(y2-y1)/(x2-x1)
slope=(6-7)/(-8-(-5))=-1/(-8+5)=-1/-3=1/3

pick any point
(x,y)
(-5,7)

y-7=1/3(x+5) or
y-6=1/3(x+8)

Two boxes have the same volume. One box has a base that is 5cm by 5cm. The other box has a base that is 10cm by 10 cm. How many times as tall is the box with the smaller base?

What is the volume of a cuboid?

We know the volume of a cuboid is the product of its length, breadth, and height or v = l×b×h.

Given, we have two boxes let us denote them by B₁ and B₂ and their respective heights are h₁ and h₂.

To obtain how many times one box is relative to the other we have to equate their respective volumes.

Given, one box has a base that is 10cm by 10 cm and another box has a base that is 5cm by 5cm.

∴ 5×5×h₁ = 10×10×h₂.

25h₁ = 100h₂.

h₁ = 4h₂.

So, h₁ is 4 times taller than h₂.

Human somatic cells contain ___ chromosomes. a. 16 b. 26 c. 46 d. 56

Answers

The answer is c. 46

In a human diploid somatic cell (2n), there are 22 chromosomes present in two copies and 1 pair of sex chromosomes. This means there are 23 pairs of chromosomes - 22 pairs of autosomes and 1 pair of sex chromosomes. There are in total 46 chromosomes (23 pairs in 2 copies: 23 
× 2 = 46).
