Which expression is equivalent to 28(15+9) ?

1 answer:

8 0

You would use PEMDAS Parentheses, Exponents, Multiplication/Division, Addition/Subtraction. So first we would use P in PEMDAS witch is 15+9=24

Then you would use Multiplication 24 x 28 = 672

So your answer would be 672

By applying the rules of probability to the following cross, Rr x Rr, determine the probability of the offspring being homozygou

Yanka [14]

Using the Punnette Square :
R r
R RR Rr 
r Rr rr
Hence,
By applying the rules of probability Rr x Rr, the probability of the offspring being homozygous recessive will be one fourth or a quarter.
SO the best is :

B. 1/4

Can someone please explain C-12=-4 to me

nlexa [21]

Answer:

C = 8

Step-by-step explanation:

So to get C by itself, we need to add 12 to both sides of the equation, which is the opposite of subtracting:

C - 12 = -4

C - 12 + 12 = -4 + 12

C = 8

The ratio of cassette to compact disc is 10 to 3 and the number of cassettes is 10 less than 5 times the number of compact discs

OlgaM077 [116]

There are 20 cassettes.

Step-by-step explanation:

Given,

Ratio of cassette to compact disc = 10:3

Let,

the number of cassettes = 10x

Number of compact disc = 3x

According to given statement;

the number of cassettes is 10 less than 5 times the number of compact discs.

10x = 5(Number of CD) - 10

$10x=3(5x)-10 \\10x=15x-10\\10=15x-10x\\10=5x\\5x=10$

Dividing both sides by 5

$\frac{5x}{5}=\frac{10}{5}\\x=2$

Number of cassettes= 10x = 10(2) = 20

There are 20 cassettes.
