Carlos sold 7 cherry pies and 4 blackberry pies for a total of $71. Elisa sold 3 cherry pies and 4 blackberry pies for a total of $51. What is the cost each of one cherry pie and one blackberry pie?
The cost of one cherry pies is $ 5 and the cost of one blackberry pies is $ 9.
Let the cost of cherry pies be x and the cost of blackberry pies be y.
In case of Carlos, we get the equation as:
7 x + 4 y = 71 …(1)
In case of Elisa, we get the equation as:
3 x + 4 y = 51
4 y = 51 - 3 x …(2)
Put equation (2) in equation (1)
7 x + 51 - 3 x = 71
4 x = 71 - 51
4 x = 20
x = 20 / 4
x = 5
4 y = 51 - 3 (5)
4 y = 51 - 15
4 y = 36
y = 36 / 4
y = 9
Therefore, we get that, the cost of one cherry pies is $ 5 and the cost of one blackberry pies is $ 9.

A rental car company charges $37. 50 per day to rent a car and $0. 05 for every mile driven. Alyssa wants to rent a car, knowing that: she plans to drive 100 miles. She has at most $200 to spend. Write and solve an inequality which can be used to determine xx, the number of days alyssa can afford to rent while staying within her budget
Answer: 4 Days
Step-by-step explanation:
To drive a 100 miles you would do 0.05*100=5
it cost 37.50 everyday and if you add the 5.00 it would cost to drive the 100 miles you get 42.50-200=157.50
37.50*4=150+42.50=192.50
she could rent the car for 4 days

The confidence interval lies between (0.827754, and 1.77225).
What is confidence interval ?
An area created using fixed-size samples of data from a population( sample space) that follows a particular probability distribution is known as a confidence interval. A named population statistic is erected into the interval with a specified probability. A confidence interval is a range of estimates for an unknown parameter in frequentist statistics. The 95 confidence position is the most popular, still other situations, similar to 90 or 99, are sometimes used when calculating confidence intervals. A confidence interval is a set of figures that we're nicely confident represent our true value. A named population statistic is erected into the interval with a specified probability.Here, sample mean x = 1.3
sample standard deviation s = 0.45
and sample size n = 6
The 95% confidence interval for the mean waste recycled

A. It is translated 3 units down and reflected over the x-axis.
B. It is horizontally compressed by a factor of 3 and reflected over the x-axis.
C. It is translated 3 units down and reflected over the y-axis.
D. It is horizontally stretched by a factor of 3 and reflected over the y-axis
It is horizontally compressed by a factor of 3 and reflected over the x-axis.
How to determine the transformation?The parent function is given as:
y = 1/x
When the above function is compressed by a factor of 3, the function becomes
y = 1/3x
Next, when the above function is reflected over the x-axis or the y-axis, the function becomes
y = -1/3x
Hence, the transformation is (b) it is horizontally compressed by a factor of 3 and reflected over the x-axis.

From the given scatter-plot, we have that:
Point (25, 125) means that the monthly home heating bill was of $125 for a month with average temperature was of 25ºF.The plot shows that, in general, as the average monthly temperature increases, the amount of the monthly home heating bill decreases.What does a scatter plot show?A scatter plot shows a series of points (x,y), relating the input x to the output y.
For the scatter-plot in this problem, we have that:

Rehan is on holiday in the USA.
Rehan buys
1 pair of trainers costing $60
The exchange rate is $1 = £0.749
Rehan says,
“The trainers cost less than £40”
Rehan is wrong.
Using a suitable approximation, estimate the cost of the trainers in pounds
The cost of the trainers in pounds which is $60 in the USA is £44.94
What is exchange rate?
The exchange rate between the dollar and the pound sterling is the amount at which both currencies exchange hands, I mean the amount of pound sterling that is given in lieu of $1, in this case, for every $1, the amount of pound sterling that is equivalent to it is £0.749, which means that on the basis of the exchange rate the value of trainers in pounds can be determined as shown in details below:
$1 = £0.749
$60=60*£0.749
$60=cost a pair of trainers=£44.94

The dimensions of the rug which Abdul would use in discuss as described in the task content are; 21.84 ft by 21.84 ft.
What are the dimensions of the rug rounded to the nearest hundredth?It follows from the task content that the dimensions of the rug which Abdul would use in the room in discuss are to be determined.
Since the room Abdul wants to put a rug on is; 775 ft² and the room is a square room.
It follows that all sides of the room are equal and the length of each side can be determined as;
s = √Area; since Area = s².
s = √775
s = 27.839 ft.
Hence, the dimensions of the room is; 27.839 ft by 27.839 ft.
However, since he wants to leave a 3-foot border of bare floor on each side, it follows that the dimensions of the rug on each axis would be;
= 27.839 - 3 -3 = 21.839 ft on all sides.
Consequently, the dimensions of the rug rounded to the nearest hundredth are; 21.84 ft by 21.84 ft.

Given that,
Kelsey spends $24 on a pullover and $17.95 each on numerous pairs of uniform pants. At a different store, Jeana purchases a sweater for $18 and several pairs of uniform pants for $18.95 apiece.
Cost for Kersey is reportedly;
$17.95 per pair of pants

Step-by-step explanation:
the equation of a line in slope= intercept form is
y = mx + b (m is the slope and b the y- intercept )
here slope m = - 1 , then
y = - x + b ← is the partial equation
to find b substitute (- 3, - 1 ) into the partial equation
