Answer:
$2.48
Step-by-step explanation:
Let cost be c
So we can say 109% of the cost is the selling price.
109% means 1.09. Thus we can setup an equation to find the cost, c.
1.09c = 29.99
c = 29.99/1.09
c = 27.51
<em>The </em><em>markup is selling price - cost</em><em>, hence,</em>
<em>29.99 - 27.51 = </em><em>$2.48</em>
Rearrange the product
(5.91 * 10^(-3)) * (8.7 * 10^10)
as
(5.91 * 8.7) * (10^(-3) * 10^10)
We have 5.91 * 8.7 = 51.417, and 10^(-3) * 10^10 = 10^(10 - 3) = 10^7, so the original product above reduces to
51.417 * 10^7
We can "add" powers of 10 by moving the decimal place to the left:
51.417 = 5.1417 * 10
so that
51.417 * 10^7 = (5.1417 * 10) * 10^7 = 5.1417 * 10^8
Answer:
A and C
Step-by-step explanation:
Just plug in the point into the equations:
a) 14 = 2(4.5) + 5
14 = 9 + 5 14 = 14 A is correct
b) 14 = 3(4.5) + 1.5
14 = 13.5 + 1.5 14 ≠ 15 B is not correct
c) 14 = 4(4.5) - 4
14 = 18 - 4 14 = 14 C is correct
d) is not correct 12 is already to large and 10 is not a negative so it is far to large
Answer:
C. 0.366
Step-by-step explanation:
In this stemplot, it is apparent that the number on the right is the least-significant digit (thousandths digit) of the batting average. The two most-significant digits are to the left of the vertical line.
Hence the value 0.36 | 6 represents an average that is 36 hundredths plus 6 thousandths: 0.366.
Answer:
Here we want to complete the blank to make the equality true:
( ) = (2 - 6)*(-4)
The equality is true if we have the same value in both sides, so we can think of this as an algebraic equation:
x = (2 - 6)*(-4)
We just need to find the value of x.
Then let's solve the right side:
x = (2 - 6)*(-4) = (-4)*(-4)
Remember the rule of signs:
(-)*(-) = (+)
x = (-4)*(-4) = 4*4 = 16
Then we need to complete the blank with the number 16
(16) = (2 - 6)*(-4)
