Last week at best bargain, 75% of computers sold were laptops. If 340 computer were sold there last week, how many laptops were sold?

Answers

Total number of computers sold last week from Best Bargain = 340
Percentage of laptops sold last week from Best Bargain = 75%
These are the information's that we can find given in the question. Based on these information's the answer to the question can be easily found.
Number of laptops sold from Best Bargain last week = 340 * (75/100)
   = 340 * (3/4)
      = 85 * 3
   = 255
So out of the total of 340 computers sold from Best Bargain last week, 255 were laptops. I hope this is the answer you were looking for.

Answer:

c=5.9/6(G)

Step-by-step explanation:

first find the 2 distances.

a^2+b^2=c^2 c=2.4+.7

7^2+2.4^2=c^2 c=3.1

.49+5.85=c^2

c^2=6.34

c=√6.34

c=2.51.

next subtract the two distances to find the difference.

c=2.51-3.1

c=.59

so the distance would be .59 which can be rounded up to .60/G

Maya makes 5 bracelets in 2/3 hour how many can she make in 1.5 hours How many bracelets does Maya braid in 1 1/2 b hours?

Answers

If Maya makes 5 bracelets in 2/3 hours, then she can make approximately 11 bracelets in 1.5 hours.

How many bracelets can Maya braid in 1.5 hours?

Given the parameter:

Maya makes 5 bracelets in 2/3 hours.

How many can she make in 1.5 hours?

To determine the number of bracelets Maya can make in 1.5 hours, we can set up a proportion.

Let 'x' be the number of bracelets in 1.5 hours

(5 bracelets) / (2/3 hour) = (x bracelets) / (1.5 hours)

Solve for x:

x × 2/3 = 5 × 1.5

x × 2/3 = 5 × 3/2

2x/3 = 15/2

2x × 2 = 3 × 15

4x = 45

x = 45/4

x = 11.25

x ≈ 11 bracelets

Therefore, she can make approximately 11 bracelets in 1.5 hours.

The function f(x) = A * x ² + Bx + C has a local minimum at 0, and its graph contains the points (0,2)and (1,8). Find A, B, and C. 6. For the function f(x) = a * x ³+ b * x ² , find a and b so that the point (1,6) is an inflection point of f.

Answers

Final answer:

The values A, B, and C for the first function are 6, 0, and 2 respectively. For the second function, a = 6, b = 0.

Explanation:

Since the function f(x) = Ax² + Bx + C has a local minimum at 0, then B = 0, because the derivative of a quadratic is 2Ax + B, and this must equal 0 if there's a local minimum. The function contains the point (0,2), giving us C=2. It also goes through (1,8), which gives us the equation A + 2 = 8, or A=6.

For f(x) = ax³ + bx², the inflection point formula gives 2b = 0, meaning b=0. Since the point (1,6) is on the graph, we can substitute into the equation to find a = 6.

Sweatshirt = $32 t-shirts = $14 ,Which costs more, 14 sweatshirts or 32 t-shirts?What property can be used to find the answer.

Answers

Cost of a sweatshirt = $32
Then
Cost of 14 sweatshirts = (32 * 14) dollars
= 448 dollars
Cost of a t-shirt = $14
Cost of 32 t-shirts = (32 * 14) dollars
= 448 dollars
So it can seen from the deduction that the cost of 14 sweatshirts and 32 t-shirts comes out to be same and equal to $448. I hope the answer and the procedure of doing this problem is clear to you. It is important to look at all the details given in the question and then start solving the problem.

14 sweatshirts would cost:
14 sweatshirts* ($32/ 1 sweatshirt)= $448.
(Note that the unit cancels out, so you get the answer)

32 T-shirts would cost:
32 T-shirts* ($14/ 1 T-shirt)= $448.
(Note that the unit cancels out, so you get the answer)

The cost of 14 sweatshirts and 32 T-shirts is equal~
