Percent error = (error / actual) x100
(2 / 12) x 100 = 16.6 recurring

Answer:

16.7% (rounded)

Step-by-step explanation:

Step 1. Make a proportion, which is 2/12 times x%/100

Step 2. Cross multiply = 2*100/12

Step 3. Solve = 16.(6) or, 16.7% rounded!

A ball is dropped from a height of 8 feet. If every time it bounces, it bounces 60% of its previous height, what is the total di
vladimir1956 [14]

Answer:

<h3>20feet</h3>

Step-by-step explanation:

Initial height of the ball = 8feet

If it bounces 60% of its previous height, its new height will be;

60% of 8

= 60/100 * 8

= 480/100

= 4.8 ft

If it bounces 60% of its current distance, new height will be expressed as;

60% of 4.8

= 0.6 * 4.8

= 2.88

The height of the ball will keep reducing and form a geometric progression of the form 8, 4.8, 2.88...

In order to get the total distance traveled by the ball, we need to calculate the sum to infinity of the sequence;

S∞ = a/1-r where;

a is the first term = 8

r is the common ratio

r = \frac{4.8}{8} = \frac{2.88}{4.8}\\r =  0.6

Substitute into the formula;

S∞ = a/1-r

S∞ = 8/1-0.6

S∞ = 8/0.4

S∞ = 20feet

Hence the total distance traveled by the ball is 20feet

Slove 4x -3=9<br>Plz due tomorrow​
IgorLugansk [536]
X=3 is the answer

1.) add 3 to the other side, so add it to 9

2.) you are then left with 4x=12

3.) solve for x, so divide 12 by 4 and you get 3!

Solve the equation x2 + + 7x= 30
antiseptic1488 [7]

Answer:

x^2+7x=30

x^2+7x-30=0

Here a=1,b=7 and c=-30

Now,

Discriminant(D)=b^2-4ac

=7^2-4×1×(-30)

=49+120=169

By applying Quadratic formula

x=-b+- root over b^2-4ac÷2a

=-7+- root over D ÷ 2×1

=-7 +- root over 169 ÷2

=-7 +- 13 ÷2

Now,

Either x=-7+13÷2=6÷2=3

Or x=-7 -13 ÷2=-20÷2=-10

Hence, ans is (C) x=-10 and x=3
