Answer:

42

Step-by-step explanation:

How to do the problem:
Assuming that you mean you want 12% of the number 80 and showing work, here is the answer:

To get X percent of any number, write the percent as a decimal and then multiply that decimal by the whole.

What I mean:

You want 12% of 80
so first change 12% into a decimal
12% is equal to .12 as a decimal

Then multiply that decimal by the whole
Since you want 12%  of 80, 80 is the whole

that means you do .12 * 80
which is equal to 9.6
Thus(answer)
12% of 80 = 9.6

Answer:

2=5

4=6

6=7

8=8

Step-by-step explanation:

The formula is 4+.5(x)=

So multiply 0.5 by 2 which gives you 1 then add 4 which gives you 5.

To get 6 for 4, you multiply 0.5 by 4 which gives you 2 then add 2+4.

for 6, multiply 0.5 x 6=3 and then 3+4= 7

for 8, multiply 0.5 x 8=4 then add 4+4= 8

Answer:

A = 6

Step-by-step explanation:

4(3A - 4) = 56 (Distribute/multiply the 4 to everything inside the parentheses)

12A - 16 = 56 (Add 16 to both sides to get A on one side)

12A = 72 (Divide both sides by 12 to get A by itself)

A = 6

Answer:

A = 6.

Step-by-step explanation:

4(3a-4)=56

distribute

12a-16=56

add 16

12a = 72

divide by 12

a = 6

The first step is to change the division operation into multiplication.

When dividing a fraction by another fraction, the first step is to change the division operation into multiplication. This can be done by using the concept of reciprocal or multiplicative inverse.

Reciprocal or multiplicative inverse of a fraction is a fraction that, when multiplied by the original fraction, gives a product of 1. In other words, if we have a fraction a/b, then its reciprocal is b/a.

So, the first step when dividing a fraction by a fraction is to find the reciprocal of the second fraction (the divisor). Let's say we have the fraction a/b divided by c/d. The reciprocal of c/d is d/c.

After finding the reciprocal, the division problem is transformed into a multiplication problem. We can rewrite the expression as follows:

(a/b) ÷ (c/d) = (a/b) × (d/c)

Now, we can multiply the fractions using the multiplication rules for fractions. Multiply the numerators (a and d) to get the new numerator, and multiply the denominators (b and c) to get the new denominator:

(a/b) × (d/c) = (a × d) / (b × c)

This is the first step when dividing a fraction by a fraction. Once you have obtained the product (a × d) / (b × c), you can simplify it further if necessary.

Answer:

25.9 years

Step-by-step explanation:

The half life of an isotope is related to the actual amounts by the equation:

N = Ni*(1/2)^(t/HL)

where N and Ni are the final and initial (Ni) amounts, t is the time (in years for this problem) and HL is the half-life, in years.

In this problem, we can write:

100 = 360*(1/2)^(x/14)

I'll reduce this to:

1 = 3.6*(1/2)^(x/14)

This can be solved by taking the log of both sides.

x = 25.87 or 25.9 years

Answer:

97 degrees

Step-by-step explanation:

Angle d and the angle to the right of angle c are alternate interior angles. This means that these angles are congruent. The angle next to angle c is equal to 180-83 degrees, which is the same as 97 degrees. So, angle d has a value equivalent to 97 degrees.
