Fatimah is driving at 1.5 km in 2 min. What is distance she covered in 2 1/4 h?

Answers

Answer:

101.25 km

Step-by-step explanation:

To solve, we need to first find how much she drives in one minute and then multiply that by the number of minutes she drives.

1.5 km = 2 minutes

divide both sides by 2.

1 minute = 0.75 km

2.25 hours = 2.25 * 60 =  135 minutes

Multiply the speed by the time to find distance.

135 * 0.75 = 101.25 km

Thus, she covered 101.25 km in 2 1/4 hours.

101.25km

Step-by-step explanation:

Answer:

2b + 9 = ?

Step-by-step explanation:

First you do commutative property, meaning you switch the numbers with ones they correspond to.

(3b-b)+(7+2)=

Then you find the sum/difference.

2b + 9 =

Since b has no number with it, just count it as a one for now. You would then do a one step equation. This would be the equation simplified.

When multiplying or dividing both sides of an inequality by a negative number, the direction of the inequality symbol is flipped. True or false?

Answers

Answer:

true

Step-by-step explanation:

Example:

2 > 1 is true.

Now, multiply both sides by -1.

-2 > -1 is false.

To make the inequality true, after multiplying or dividing by a negative number, you must flip the inequality sign.

-2 < -1 is true.

true when dividing or multiplying by a negative number in an inequality the sign will flip.

Mrs. Stewart has 8 minutes to enter 120 test grades into her computer. What is the minimum rate at which she should be entering the grades if she wants to finish in time?
A. 4 grades per minute
B. 15 grades per minute
C. 16 grades per minute
D. 960 grades per minute

Answers

Answer:

C. 15 grades per minute.

Step-by-step explanation:

Divide 120 by 8

120÷8=15

It's 15 because multiplying it by 8 instead of dividing it gives you 120.

C. 15 grades per minute

If you do 15x8 you get 120 so if you reverse it and use division 8 divided by 120 you get 15

Answer:

A) solution 2 is more acidic than solution 1

Step-by-step explanation:

A chemist prepares two acid solutions:

Solution 1: 3 parts sulfuric acid to 7 parts water

Ratio of sulphur to water: 3/7 (3:7)

Solution 2: 4 parts sulfuric acid to 9 parts water

Ratio of sulphur to water: 4/9 (4:9)

___________________________________________________

Part A: (using ratios to determine which solution is more acidic)

First we make same denominator, since the denominators are 9 and 7, we have to find the lcm (lowest common multiple) they both have with is 63. To do that, we must multiply the denominators with either 7 or 9.

Solution 1: Numerator (3) multiplied by 9 and then denominator (7) multiplied by 9. This makes out fraction/ratio 27/63

Solution 2: Numerator (4) multiplied by 7 and then denominator (9) multiplied by 7. This makes out fraction/ratio 28/63

Since 28/63 (or just 28) is a larger quantity than 27/63 (or just 27) this means solution 2 is more acidic than solution 1.

Mathematical Line (Not sure what you would call this lol): 28 > 27

Part B: (Let 'y' amount of sulfuric acid mix with 'x' amount of water)

Equation of solution 1: y = 3/7x

Equation of solution 2: y = 4/9x

Please find attachment for graph.

Part C: Don't have a graph, sorry! (part a. method is more preferred to find more acidic because it gives the actual acidic amount.)

Answer:

A = 324m²

Step-by-step explanation:

Formula for finding the surface area of a rectangular prism:

2(wl + hl + hw)

First, let's find out which one of the measurements is the height, length, or width.

6m = length

16m = width

3m = height

Next, we calculate the surface area. We have to do the formula one by one too.

2(wl + hl + hw)

2(16x6 + 3x6 + 3x16)

16 x 6 = 96

3 x 6 = 18

3 x 16 = 48

Now, we add those together.

96 + 18 + 48 = 162

Lastly, multiply by 2.

162 x 2 = 324

Therefore, A = 324m²

Answers

Answer:

Step-by-step explanation:

Answers are A and B.

Facts given are :

Current height    = 6 ft

Growth per year = 1.5 ft

Final height         = 27

Explanation for A:

Assume it takes 'x' number of years.

initial height + growth in 'x' years = Total height of the tree after 'x' years

                                          6 + 1.5x = 27

                                                 1.5x = 27 -6 = 21

(1.5 can be written as 3/2)      3x/2 = 21

                                                     3x = 42

                                                       x = 14

hence, number of years = 14

Explanation for B:

After 'x' years,

Final height - initial height = Growth in 'x' years

27 - 6 = Growth in 'x' years

21=Growth in 'x' years = 1.5x

21= 3x/2

42=3x

14=x

hence, number of years = 14

The answers are A & B.

The Hiking Club is taking another trip. The hike leader's watch shows that they gained 296 feet in altitude from their starting position
Their altitude is now 285 feet, but there is no record of their starting altitude.
Write and solve an equation to represent this situation and find their starting altitude.

Answers

We can start by using the information given to set up an equation that represents the situation. Let x be the starting altitude.

We know that:

   The starting altitude + the altitude gained = the current altitude

   The current altitude is 285 feet

   The altitude gained is 296 feet

So, we can write an equation to represent this situation as:

x + 296 = 285

To find the starting altitude, we need to solve for x. To do this, we'll subtract 296 from both sides of the equation:

x + 296 - 296 = 285 - 296

x = -11

However, an altitude of -11 feet is not possible. We can infer that the starting altitude is actually 0 feet.

So the starting altitude is x=0 feet
