If BC=6.7, CD=6.2, and AD=13.3, find AB to the nearest tenth

Answers

Answer:

The answer is 14.4 units.(option A)

Step-by-step explanation:

Angles BAC and CAD are equal.

We can solve this by using the proportional relation.

(AB)/(BC) =(AD)/(CD)

Let AB be = x

So, (x)/(BC) =(AD)/(CD)

(x)/(6.7) =(13.3)/(6.2)

(x)/(6.7) =2.145

x=6.7*2.145 = 14.37 units

And rounding to nearest tenth, we get 14.4 units.

Answer:

14.4

Step-by-step explanation:

AB / BC = AD/CD

AB/6.7 = 13.3 / 6.2

AB = 13.3 * 6.7 / 6.2

AB = 14.4

Mike says that 3/3 o his fraction model is shaded blue. Ryan says that 6/6 of the same model is shaded blue. Are the two fractions equivalent? If so, what is another equivalent fraction?

Answers

Yes, these fractions are equivalent. If you were to multiply the numerator and the denominator of 3/3 by 2, you would get 6/6, meaning that they are equivalent. These fractions are also equal to one whole, which is any fraction where both the top and bottom (numerator and denominator) are the same number, so 1/1, 2/2, 3/3, 4/4, 5/5, 6/6, 7/7, 8/8, etc. are all equal.
yes, 3/3 and 6/6 are equivalent. some other equivalent fractions are:
1/1
2/2
4/4
5/5
7/7
8/8
9/9
10/10

Answers

Independent variable is a variable that does not change when circumstances change.

Dependent variable is a variable that changes when circumstances change. Usually dependent on the changes that occurs in the independent variable.

1) Number of pizzas Horton delivers - D.) INDEPENDENT VARIABLE
2) The vehicle Horton Uses - A.) BOTH THE INDEPENDENT VARIABLE AND THE DEPENDENT VARIABLE
3) The amount of money Horton makes - B.) DEPENDENT VARIABLE
4) The number of miles Horton drives during deliveries. - C.) NEITHER THE INDEPENDENT NOR THE DEPENDENT VARIABLE

Only B is needed. Lots of points. Please help. Thanks.
