Answer:
$67.50
Step-by-step explanation:
Multiplying $100 by 0.75 results in $75. This price reflects the 25% off discount.
Multiplying this $75 by 0.90 results in $67.50. This price reflects both the initial 25% discount and the additional 10% discount.
1. 30% decrease
2. 33 1/3% increase
Step by step explanation:
Question 1.
$50 to $35 is a decrease, because 35 is smaller than 50.
(50-35)/50 * 100%
= 15/50 * 100%
= 30%
Ans: 30% decrease
Question 2.
150 days to 200 days is an increase because 200 is large than 150.
(200-150)/150 * 100%
= 50/150 * 100%
= 1/3 * 100%
= 33 1/3% or 100/3%
Ans: 33 1/3% increase
The <em><u>correct answer</u></em> is:
Explanation:
An exponential function is of the form
, where a is the initial population, b is 1 plus the amount of yearly change, and x is the number of years.
For our problem, a, the initial population, is 1500.
The yearly change is 6.3%; 6.3% = 6.3/100 = 0.063. Since it is decreasing, this is negative; 1+(-0.063) = 0.937.
We use t as the number of years.
This gives us
Answer:
C. d < 2
Step-by-step explanation:
Note that the dot is open, which means that it is not including the number 2 (as the dot is on 2), so you use either < or >. Now, note that the arrow is pointing towards the left, or <em>less than</em>. This means you will use < as your sign.
d < 2 is your answer

Answer:
<em>-9.5 + 6x ≥ 42.1 </em>
<em>6x ≥ 51.6</em>
x ≥ 8.6
Here, we can see that x is greater than or equal to 8.6. So, we can say that 8.6 is the lowest value of x
but we have 2 options with 8.6 as the lowest term, we can see that the brackets are different in the beginning
the '[' bracket tells us to include 8.6 in the values of x whereas the '(' bracket tells to exclude 8.6 from the possible values of x
since we know that x is greater than or equal to 8.6, we will use the '[' bracket
Hence, b is your answer
