Answer:

Distributive law, in mathematics, the law relating the operations of multiplication and addition, stated symbolically, a(b + c) = ab + ac; that is, the monomial factor a is distributed, or separately applied, to each term of the binomial factor b + c, resulting in the product ab + ac. From this law it is easy to show that the result of first adding several numbers and then multiplying the sum by some number is the same as first multiplying each separately by the number and then adding the products.

Step-by-step explanation:

a(a+b)

in this question first a will multiply by a+b.

like this;

a(a+b)

= a(a)+ab

= a^2+ab

Which ratios form a proportion
Lelu [443]

Answer:

C

Step-by-step explanation:

To form a proportion, you need two equal ratios.

Divide the numerator by the denominator of all fractions.

Any two fractions that are equal are a proportion.

A.

4/9 = 0.4444...

9/4 = 2.25

Fractions are not equal. Not a proportion.

B.

4/10 = 0.4

10/25 = 0.4

Fractions are equal. Proportion

C.

4/11 = 0.363636...

6/13 = 0.46153846...

Fractions are not equal. Not a proportion.

D.

I can't read the fractions, but do the same I did above.

Divide each numerator by the denominator and compare the decimals. If they are equal its a proportion. If theya re not equal, it is not a proportion.

Winston ears 140$ by selling 56 hotdogs at the concession stand at school. Using the same rate for the cost of one hot dog how m
WARRIOR [948]

The number of hotdogs that must be sold to earn $170 is 70

What is the formula for total earnings?

The total earnings can be determined as the price per hotdog multiplied by the number of hotdogs sold, which is as shown below:

total earnings=price per hotdog*number of hotdogs

total earnings(initially)=$140

price per hotdog=P

number of hotdogs=56

$140=P*56

P=4140/56

P=$2.50

Now, we need to determine the number of hotdogs required to earn $175

$175=$2.50*X

X=$175/$2.50

X=$70

A drug trial is testing the effectiveness of two drugs. If 50 patients are given Drug A, 20 patients are given Drug B, and 100 p
Vsevolod [243]
So, to find the answer you'd first add up how many patients you have:
20+50+100 = 170.
In a fraction your total would go on the bottom. Then you'd take how many patients are taking a real drug, which is represented by 20+50 = 70. This number would go on top.

So, the probability of a patient NOT getting a placebo is 70/170. Simplified would be 7/17. 

The answer is D. 7/17.
