Step-by-step explanation:
Call x: the hour of dogs keeping
y: the hour of wolves keeping
The total charge for dogs keeping: 19+ 1.5x
The total charge for wolves keeping: 14+2.75y
Total cost (19+ 1.5x)+(14+2.75y)= 1.5x+2.75y+33
A store is giving out cards labeled 1 through 10 when customers enter the store. If the card is an even number, you get a 15% discount on your purchase that day. If the card is an odd number greater than 6, you get a 40% discount. Otherwise, you get a 25% discount. The table shows the results of 400 customers. What is the relative frequency for each discount? Use pencil and paper. If the manager of the store wants approximately half of the customers to receive the 25% discount, does this seem like an appropriate method?
Answers
Answer:
The answer would be A. 1 1/5
48/40 = 1 8/40
1 8/40 Simplify to 1 1/5
Step-by-step explanation:
If the store wants to give approximately half of the customers a 25% discount. They may need to adjust the discount criteria or randomly assign cards to customers to achieve the desired frequency.
What is the relative frequency?The ratio of the number of outcomes in which a specified event occurs to the total number of trials, not in a theoretical sample space, but in an actual experiment, is the relative frequency or experimental probability of an event.
To determine the relative frequency for each discount, we need to count the number of customers who received each type of discount and divide by the total number of customers.
Let's create a table to organize the data:
Discount Card Label Number of Customers
15% Even 120
40% Odd > 6 30
25% Other 250
Total 400
The relative frequency for each discount is given by:
Relative frequency of 15% discount: 120/400 = 0.3 or 30%
Relative frequency of 40% discount: 30/400 = 0.075 or 7.5%
Relative frequency of 25% discount: 250/400 = 0.625 or 62.5%
To determine whether this discount method is appropriate to give approximately half of the customers a 25% discount, we need to compare the observed frequency of the 25% discount with the desired frequency.
Half of the 400 customers is 200. If we want approximately half of the customers to receive the 25% discount, then the observed frequency of the 25% discount should be close to 200.
However, we see that the observed frequency of the 25% discount is 250, which is higher than the desired frequency.

Alexi bought 5 T-shirts for $12 each and 3 pairs of socks for $2 a pair. Which expression shows how much Alexi spent in dollars. Explain
a) 5 × 12 x 3 × 32
b) 5 × 12 + 3 × 32
c) (5+3) × (12 + 2)
Answers
Answer:
b
Step-by-step explanation:
so hope it help,have a nice day!
Alexi bought 5 shirts. Given that each of them costs 12 dollars, we can say that the equation for their price is:
12 + 12 + 12 + 12 + 12 or just 5 x 12
Now, Alexi also bought socks. 3 pairs of them, in fact. Given that each pair was an astounding 2 dollars, we would get this equation:
2 + 2 + 2 or just 3 x 2
Of course, Alexi bought these things together, so they must pay for both things. The total price would be
5 x 12 + 3 x 2 or 66 dollars

The length of a building is 60 feet. The length of the building on a scale drawing is 4 inches. Which ratio describes the scale of the drawing?
-- giving brainliest to whoever has the answer (with descriptions and such)
-- if no one else answers (but only one person), i'll be able to give five stars and a thanks
Answers
the ratio of the scale drawing is
1 inch on the drawing represents 180 feet in real life.
To determine the ratio of the scale drawing, we need to first find the length of the building on the scale drawing. We know that the actual length of the building is 60 feet, and the length of the building on the scale drawing is 4 inches. We can set up a proportion to find the length of the building on the scale drawing:
Actual length / Length on scale drawing = Scale factor
We can plug in the values we know:
60 feet / Length on scale drawing in inches = Scale factor
To solve for the length on the scale drawing in inches, we can cross-multiply:
60 feet * 1 inch / Scale factor = Length on scale drawing in inches
Simplifying:
Length on scale drawing in inches = 60 feet * 12 inches / Scale factor
We know that the length on the scale drawing is 4 inches, so we can plug that into the equation:
4 inches = 60 feet * 12 inches / Scale factor
Solving for the scale factor:
Scale factor = 60 feet * 12 inches / 4 inches
Scale factor = 180

Use the diagram below, if m∠AEC=41°, find each angle measure
Answers
Answer:
14) AED = 139
15) CEF = 90
16) DEB = 41
17) BEF = 49
18) CEB = 139
19) AEF = 131
Step-by-step explanation:
14) DEC = 180 degrees, because it is a straight line. We know that AEC is 41 degrees, so to find AED, we just subtract DEC (180) by AEC (41) which is 139.
15) CED = 180 degrees, because it is a straight line. We know that DEF is 90 degrees, because it is a right angle, so to find CEF, we just subtract CED (180) by DEF (90) which is 90.
16) AEC = 41 degrees and we know that AEB and CED are straight lines, so that means it will be the same measurement on the other side, so DEB = 41.
17) We know that DEF is 90 degrees, because it is a right angle, and that DEB is 41 degrees, so to find BEF, we just subtract DEF (90) by DEB (41) which is 49.
18) We know that CEF is 90 degrees, because it is a right angle, and that FEB is 49 degrees, so to find CEB, we just add CEF (90) to FEB (49) which is 139.
19) We know that CEF is 90 degrees, because it is a right angle, and that AEC is 41 degrees, so to find AEF, we just add CEF (90) to AEC (41) which is 131.
