Answer:
1. $2.5
2. 2/5lb
Step-by-step explanation:
1. The blank is asking what the cost of one pound of blueberries costs and you know that two pounds costs $5, so half of 5 is 2.5. So the first blank is $2.5.
2. You know that $2.5 will get you one pound, so divide by 5 and now you know that $0.50 will get you 1/5 pound of blueberries. multiply by two and now you know that $1.00 get you 2/5 pound of berries. So the second blank is 2/5 lb.
Answer:
1. 2.50 dollars
2. 0.2 pounds
Step-by-step explanation:
Sorry if I explain things you might not understand.
1. To find how much one pound is, you solve the equation 2 / 5 = 1 / P. You solve for P which will be 2.5 or 5/2
2/5 = 1/P
2/5 x P x 5/2 = 1 / P x P x 5/2
P = 5/2
2. To find the amount of pounds per dollar, you solve the equation 5/2 = 1/D. You solve for D which will be 2/5 or 0.2 dollars.
5/2 x D x 2/5 = 1/D x D x 2/5
D = 2/5

The cost to install x number of central air conditioning units for a company is given by the function C(x) = 4000x +1300/3 Use the function to determine the cost to install 45 air conditioners
Given:
The cost to install x number of central air conditioning units for a company is given by the function
[tex]C(x)=\dfrac{4000x+1300}{3}[/tex]
To find:
The cost to install 45 air conditioners.
Solution:
We have,
[tex]C(x)=\dfrac{4000x+1300}{3}[/tex]
Putting x=45, we get
[tex]C(45)=\dfrac{4000(45)+1300}{3}[/tex]
[tex]C(45)=\dfrac{180000+1300}{3}[/tex]
[tex]C(45)=\dfrac{181300}{3}[/tex]
[tex]C(45)=60433.3333...[/tex]
[tex]C(45)\approx 60433.33[/tex]
Therefore, the cost to install 45 air conditioners is $60433.33.

Mrs. Miller’s students pull marbles from a bag containing two red, three blue, and five green marbles. They pull a marble, don’t replace it and then pull another marble. What is the probability of a student selecting two red marbles in a row?
Answer:
1/45
Step-by-step explanation:
Probability of pulling a red marble is 2/10. If you do not replace the marble, then there are only 9 marbles left in the bag. Assuming you pulled a red marble the first time, this leaves only 1 red marble in the bag. So, the probability of pulling a red marble the second time is 1/9. The probability of pulling two red marbles is (2/10)(1/9) = 1/45

Find the equation of the line through point (−2,−1) and perpendicular to 5x+6y=−6.
Step-by-step explanation:
When lines are perpendicular to each other
multiplying their gradients(m) will equal to - 1
so , m1 × m2 = -1
1st:Find m1
5x+6y= -6
make y the subject,
6y= -5x -6
[tex]y = \frac{ - 5x - 6}{6} [/tex]
y= -5/6x - 1
because y = mx + c
m1 = -5/6
2nd:find m2
-5/6 × m2 = -1
m2 = 6/5
3rd: substitute m2 and the coordinates into y=mx+c
y=mx+c
-1= (6/5)(-2)+c
-1 = -12/5 + c
-5 = -12 + c
-5+12= c
c = 7
4th: substitute m2 and c into y= mx+c to find the equation the line
y =6/5x + 7 (Ans)
As per slope-intercept form, the equation of the line through point (−2,−1) and perpendicular to 5x + 6y = -6 is 5y = 6x + 7.
What is the slope-intercept form of a straight line?The slope-intercept form of a straight line is y = mx + c.
Here, 'm' is the slope and 'c' ix the y-intercept of the given line.
The given equation is 5x + 6y = - 6
Therefore, in slope-intercept form, this equation will be:
y = - 5x/6 - 1
Therefore, the slope of this line is m = - 5/6 and the y-intercept is c = - 1.
The required line is perpendicular to the given line.
Therefore, the slope of the required line is
= - 1/m
= 6/5
Again, the required line passes through the point (- 2, - 1).
Therefore, - 1 = - 2(6/5) + c
⇒ c = - 1 + 12/5
⇒ c = 7/5
The equation of the required line is
y = (6/5)x + 7/5
⇒ 5y = 6x + 7

Adrian has a points card for a movie theater.
He receives 20 rewards points just for signing up.
He earns 2.5 points for each visit to the movie theater.
He needs at least 35 points for a free movie ticket.
Write and solve an inequality which can be used to determine vv, the number of visits Adrian can make to earn his first free movie ticket.
Answer: v ≥ 6
This means that Adrian needs to do at least 6 visits.
Step-by-step explanation:
First, we know that he gets 20 points just for signing up, so he starts with 20 points.
Now, if he makes v visits, knowing that he gets 2.5 points per visit, he will have a total of:
20 + 2.5*v
points.
And he needs to get at least 35 points, then the total number of points must be such that:
points ≥ 35
and we know that:
points = 20 + 2.5*v
then we have the inequality:
20 + 2.5*v ≥ 35
Now we can solve this for v, so we need to isolate v in one side of the equation:
2.5*v ≥ 35 - 20 = 15
2.5*v ≥ 15
v ≥ 15/2.5 = 6
v ≥ 6
So he needs to make at least 6 visits.
Answer:
2.5v+20=35
V=6

Olivia has a points card for a movie theater. She receives 25 rewards points just for signing up. She earns 7.5 points for each visit to the movie theater. She needs 130 points for a free movie ticket. How many visits must Olivia make to earn a free movie ticket?
Answer:
0 visits
Step-by-step explanation:
According to the scenario, calculation of the given data are as follows,
Rewards for signing up = 80 points
Reward per visit = 2.5 points
Total points needed = 105
Let, number of visits = x
So, we can calculate number of visits by using following formula,
80 + (2.5 × X) = 105
2.5X = 105 - 80
2.5X = 25
X = 25 ÷ 2.5
X = 10 visits.
Hence, Olivia needs to make 10 visits in order to earn a free movie ticket

\a truck travels at an average of 55 miles per hour once inside city limits the truck decreases it speed by 40 percent what is the speed in city limits
Answer: 33 mph
Step-by-step explanation:
First find out what 40% of 55 is:
= 40% * 55
= 22 mph
This means that the speed reduces by 22 mph inside the city.
The speed inside the city is therefore:
= 55 - 22
= 33 mph

Answer:
5 carwashes, Josh: $ 100 savings, Sandra: $100 savings
Step-by-step explanation:
First we need to find each of their formulas.
Formula for Josh: 50+10c=s
Formula for Sandra:25+15c=s
We can set these two to be equal to each other in order to find how many carwashes it takes for them to have the same amount of money.
50+10c=25+15c
25+10c=15c
25=5c
c=5
after 5 car washes, they will have the same amount of money.
now that we know that, we can plug that into each equation to find each of their savings after the 5 carwashes.
Josh's savings:
50+10c=s
plug in the amount of carwashes,
50+10*5=s
50+50=s
s=100 dollars of savings for Josh
Sandra's savings:
25+15c=s
plug in the amount of carwashes,
25+15*5=s
25+75=s
s=100 dollars of savings for Sandra

The value of x is the square root of an integer, and the value of y is an integer greater than zero. C. The value of x is an integer less than zero, and the value of y is an integer greater than zero. D. The value of x is a square root that can be simplified to an integer, and the value of y is an integer less than zero.
Answer:
Negative integers, or numbers below zero, are still whole numbers- just not positive whole numbers. This should help you.
Step-by-step explanation:
The statement describes values of x and y such that could be an irrational numbers, the value of x is the square root of an integer, and the value of y is an integer greater than zero.
We have given that the value of x and y,
such that could be an irrational number.
What is irrational numbers?An irrational number, any real number that cannot be expressed as the quotient of two integers.
Negative integers, or numbers below zero, are still whole numbers- just not positive whole numbers.
Therefore we can conclude that
The statement A, C, or D do not show the irrational numbers
because they all are stated as integers,
which cannot be irrational.
Therefore option B is correct.
The value of x is the square root of an integer, and the value of y is an integer greater than zero.
