Answer 1

Answer:

look down

Step-by-step explanation:

well u should know that.....

1. A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other

2. A unit rate describes how many units of the first type of quantity corresponds to one unit of the second type of quantity. A proportion is an equation that states that two ratios or rates are equivalent.

3. As defined in the lesson on Unit Rate and Proportionality, the unit rate is the rate of change in a relationship where the rate is per 1.

4. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls)

Answer:

Step-by-step explanation:

(2^3)^1 does not equal 16

= 6^1

= 6

2 to the power of 3 equals 2x2x2

2x2x2 equals 6

The answer to this equation is 1.6875

Answer:

12 ÷(2 + 2/3) ^2 = 27/16= 1 11/16 = 1.6875

Step-by-step explanation:

Add: 2 + 2/3= 2/1 + 2/3 = 2 · 3/1 · 3+ 2/3 = 6/3 + 2/3 = 6 + 2/ = 8/3 It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - is LCM(1, 3) = 3. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 1 × 3 = 3. In the following intermediate step, it cannot further simplify the fraction result by canceling. In other words - two plus two-thirds is eight-thirds. Exponentiation: the result of step No. 1 ^ 2 = 8/3 ^ 2 = 82/32 = 64/9 In other words - eight-thirds raised to the power of squared is sixty-four-ninths. Divide: 12 : the result of step No. 2 = 12 : 64/9 = 12/1 · 9/64= 12 · 9/1 6= 108/64 = 4 · 27/4 · 16 = 27/16. Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 64/9 is 9/ 64) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the following intermediate step, cancel by a common factor of 4 gives 27/16. In other words - twelve divided by sixty-four ninths is twenty-seven sixteenths.

rewrite this so it does not have fractions

Answer: 19-10(-2)>0

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

−2/5 x −9< 1/2

Step 2: Add 9 to both sides.

−2/5x −9+9< 1/2+9 −2/5x x< 19/2

Step 3: Multiply both sides by 5/(-2).

(5/−2)*(−2/5x)<(5/−2)*(19/2)
