Manuel needs to buy plastic spoons. Brand Ahas a box of 12 spoons for $1.12. Brand B has a box of 25 spoons for 2.69 Find the unit price for each brand. Then state which brand is the better buy based on the unit price. Round your answers to the nearest cent. Unit price for the Brand A spoons: I for each spoon Unit price for the Brand B spoons: $] for each spoon The better buy: O Brand A O Brand B O Neither (They have the same unit price)
Answers
1.99 / 25 = 0.0796
Repeat this process for brand B:
3.89 / 42 = 0.0926
Brand A, at $0.08 a unit, is the better buy of brands A and B.
Answer:
Brand A: 0.92 Brand B: 0.11
Step-by-step explanation:
1.12 divided by 12 (round down)
2.96 divided by 25 (round up)
brand B is better to buy because you get more and it costs less per spoon

Step-by-step explanation:
If AB is a tangent to the circle then ∠ B is right angle
Using the converse of Pythagoras' identity.
If the square of the longest side is equal to the sum of the squares on the other 2 sides, then the triangle is right
longest side = 52 and 52² = 2704
48² + (10 + 10)² = 48² + 20² = 2304 + 400 = 2704
Then AB is a tangent to the circle since ∠ B is a right angle

Find the slope of the line with x intercept 9 and y intercept of -2
Answers
Answer:
2/9
Step-by-step explanation:
Find the slope of the line with x intercept 9 and y intercept of -2
Given that the equation of the line is y = mx+b
x intercept occurs when y = 0
The coordinate of x intercept is (9,0)
y intercept occurs at x = 0
The coordinate of y intercept is (0, -2)
Slope m = y2-y1/x2-x1
m = -2-0/0-9
m = -2/-9
m = 2/9
Hence the required slope is 2/9

A car is traveling at a constant speed of 60 miles per hour. Complete the table below to the distance that the car travels in hours.
Answers
The value for the first one is “d= 60t”
because that’s how much the car travels per hour.
The values for the second question is “450=60t” because 450 is the amount of miles the car traveled in total, and again the 60 is how many miles the car travels per hour.

At 7am there was 4 inches of snow on the ground. After that, the snow fell at a rate of 1.5 inches per hour. Equation:
Answers
Answer:
y(t) = 4 + 1.5t
.
Step-by-step explanation:
Initial amount of snow = 4 inches
Fall rate of snow = 1.5 inch per hour
Equation to model the scenario goes thus :
Initial amount of snow + (fall rate of snow * number of hours)
Let the number of hours = h
4 inches + (1.5 inch per hour * h)
Equation, y(t) becomes ;
y(t) = 4 + 1.5t

A biologist is studying a group of alligators in a swamp and tagged 4 hatchlings, 5 juveniles, and 6 adults. The biologist estimates that this tagged sample is a reliable reflection of the ratios of hatchlings, juveniles, and adults in the general alligator population for the area. The biologist estimates that the total number of alligators in the area is 120. The most likely number of adults in the total population is ______?
A. 32
B. 48
C. 72
D. 120
AND PLZ NO LINKSSSS
Answers
Answer:
48
Step-by-step explanation: Take the 6 adults and divide it by one of the multiple choice answers to get a ratio. The ratio of 48 / 6 = 8. You can then see if that ratio helps you add up all the alligators to 120.
4 x 8 + 5 x 8 + 6 x 8 = 120
