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

To find the price per spoon of brand A, divide the cost by the amount of spoons:

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

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.

The ratio of mango ice cream to strawberry ice cream is 2 : 5 .Total no. of ice cream is 49.what is the no. of strawberry ice cream.

Answers

Answer:

Step-by-step explanation:

First, we add the ratio of the mango to strawberry ice cream and we're going to end up with 2+5=7. If we divide 49 by 7, we're going to find out how much we need to multiply to both sides of the ratio to get the specific amounts. So, if we multiply 7 (49/7) to 5, we're going to get 35. Therefore the number of strawberry ice cream is 35.

Also, we can check this by multiplying 7 to 2 as well, where we will end up with 14. 35 + 14 = 49 so we know this is correct!

35 is Answer:

Step-by-step explanation: if you do 2:5 and like keep doing it you'll get to a number and another one and it'll make 49

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
