3/2=x/1
3=2x
x=3/2
x=1.5
so the unit rate of price per melon is 1.5
Answer:
Step-by-step explanation:
unit rate is another way of saying "slope of the line"
3/2 is the slope of the line..just from inspection of the graph
1.5 is another way to say 3/2 and that's how me might normally say the cost of one watermelon... it's a $1.50 so the unit rate is 1.5 units.. and here the units are dollars
A set of floor speakers costs $466. If the extended warranty on the speakers costs 32% of the price of the speakers, how much does the extended warranty cost
Answer: 149.12
Step-by-step explanation:
to find out the extended warranty we do,
466*(32/100)=149.12
The extended warranty cost is $149.12.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, a set of floor speakers costs $466.
If the extended warranty on the speakers costs 32% of the price of the speakers.
Now, extended price =32% of 466
32/100 ×466
= 0.32×466
= $149.12
Therefore, the extended warranty cost is $149.12.

Find the area of a circle with diameter 10 cm . Use the value 3.14 for π , and do not round your answer. Be sure to include the correct unit in your answer. Whatts the answer?
Answer:
Area of circle = 31.4 cm²
Step-by-step explanation:
Given the following data;
Diameter, d = 10 cm
π = 3.14
Area of a circle is given by the formula;
πd
Substituting into the equation, we have;
Area of circle = 3.14 * 10
Area of circle = 31.4 cm²
4. Find the value of the real number y such that
(3+2i)(1 + iy)
is :
(a) real
(b) imaginary
Step-by-step explanation:
(3 + 2i)(1 + iy)
= 3 + (3y + 2)i - 2y (because i² = -1)
For this to be real, (3y + 2) = 0. => y = -2/3
For this to be imaginary, y can be any real or complex number (except -2/3)

A financial institution offers a "double-your-money" savings account in which you will have $2 in 11 years for every dollar you invest today. What annual interest rate does this account offer? Please specify your answer in decimal terms and round your answer to the nearest thousandth (e.G., enter 12.3 percent as 0.123).
Answer:
[tex]r=0.07[/tex]
Step-by-step explanation:
From the question we are told that
An offer of 2$ in 11 years on every dollar
Generally we make use of this formula
[tex]F=P(1+r/100)^t[/tex]
where
[tex]f=Future value[/tex]
[tex]P= present value[/tex]
[tex]r=Rate[/tex]
[tex]t=time[/tex]
Mathematically solving for the rate
[tex]2=1(1+r/100)^1^1[/tex]
[tex](2)^1^/^1^1=(1+r/100)[/tex]
[tex](1+r/100=1.0650[/tex]
[tex]r=(1.0650-1) *100[/tex]
[tex]r=0.07[/tex]
Generally this shows that the account give an annual rate of 0.07

-4<-3
Step-by-step explanation:
if you are talking about what is greater than this is the answer
Answer: -10<0 -4<-3
Step-by-step explanation:-10 is less than 0 because negative(-)means that number less than 0. -4 is less than -3 because even though it’s a higher number it’s negative.
True or False? A triangle can have side lengths of 3, 3 , and 6
Answer:
No
Step-by-step explanation:
We can check with the Pythagorean Theorem.
a^2 + b^2 = c^2
a and b are always the smaller sides, the legs
c is the longer side, the hypotenuse
3^2 + 3^2 > 6^2
9 + 9 > 36
18 < 36
18 is not greater than 36, therefore this triangle can not have the side lengths 3, 3, and 6.
Select the reason that supports the following statement?
Answer:
C
Step-by-step explanation:
I think the correct answer would be C since you are using lines and angles but I am not 100 percent sure. Also because A and B wouldn't make since because it is adding.
What are the explicit equation and domain for an arithmetic
sequence with a first term of 5 and a second term of 3?
Given:
First term of an arithmetic sequence = 5
Second term = 3
To find:
The explicit formula for the given arithmetic sequence.
Solution:
We have,
First term: [tex]a_1=5[/tex]
Second term: [tex]a_2=3[/tex]
Common difference is
[tex]d=a_2-a_1[/tex]
[tex]d=3-5[/tex]
[tex]d=-2[/tex]
Now, the explicit formula for an arithmetic sequence is
[tex]a_n=a+(n-1)d[/tex]
where, a is first term and d is common difference.
Putting a=5 and d=-2, we get
[tex]a_n=5+(n-1)(-2)[/tex]
It can also be written as
[tex]a_n=5-2n+2[/tex]
[tex]a_n=7-2n[/tex]
Here, n is an integer greater than or equal to 1.
Domain is the set of input values.
Therefore, the explicit equation is [tex]a_n=5+(n-1)(-2)[/tex] or [tex]a_n=7-2n[/tex] and domain is all interest greater than or equal to 1.

Eric sells model cars from a booth at a local flea market. He purchases each model car from a distributor for $14 and the flea market charges him a booth fee of $30. Eric sells each model car for $20. How many cars will Eric have to sell to break even?
Answer: 5 cars
Step-by-step explanation:
Breakeven point = Fixed Cost/ Contribution margin
Fixed cost is $30 which is the flea market booth charge
Contribution margin is sales price less variable cost.
The Variable Cost is the amount he is charged by the distributor of $14.
Contribution Margin = 20 - 14
= $6
Breakeven point = 30/6
= 5 cars
