How can we re-write the expression below into ""friendlier"" terms? 6 ∙ 29

Answers

Answer:

A. 6 ∙ (30 - 1)

Step-by-step explanation:

How can we re-write the expression below into “friendlier” terms? 6 ∙ 29

options:

A. 6 ∙ (30 - 1)

B. 6 ∙ (16 + 13)

C. 6 ∙ (19 + 10)

D. 6 ∙ (21 + 8)

Re-writing an expression in friendlier term means expressing the term using numbers that are closest to the expression.

Checking all options,

A. 6 ∙ (30 - 1)

Option A seems closer to 6 ∙ 29 because, 30 - 1 which is very easy to evaluate gives 29

Moreover, 29 is very close to 30

Compared to other options, which have values that requires more thinking in evaluation

Laney bought 1 2/3 pounds of grapes. She also
bought bananas that were

the grapes. How much did the bananas weigh? helppppp

Answers

Answer:

The bananas weigh 3 3/4 pounds.

Answer: 3 3/4

Step-by-step explanation:

All we have to do is multiply the weight of the grapes by 2 1/4.

= 1 2/3 x 2 1/4

= 5/3 x 9/4

= 45/12

= 3 9/12

Michael has 2 liters of a 10% solution. How much of a 17% solution would he need to add to get a 15% solution?

Answers

Answer:

5 liters

Step-by-step explanation:

Let x represent the number of liters of the 17% solution, and represent the percentages as decimal values:

0.1(2) + (0.17)(x) = 0.15(x + 2)

Simplify:

0.2 + 0.17x = 0.15x + 0.3

Solve for x:

0.17x = 0.15x + 0.1

0.02x = 0.1

x = 5

So, you would need 5 liters of a 17% solution to get a 15% solution

An engineer is designing three triangular traffic signs with a computer program. The vertices of Sign A are located at (2, 2) , (2, 12) , and (17, 7) . The vertices of Sign B are located at (4,4),(11, 19) and (18, 4) . The vertices of Sign C are located at (4, 8), (24, 1) , and (24, 15) . Put the signs in order from largest to smallest perimeter. Sign A Sign B Sign C

Answers

Answer:

sign C, sign B, sign A

Step-by-step explanation:

Given the vertices of triangular post A as (2, 2) , (2, 12) , and (17, 7). Let us find the length of side of the post using the formula for calculating distance between 2 points using the formula:

D = √(y₂-y₁)²+(x₂-x₁)²

For the coordinate (2, 2) , (2, 12)

S₁ = √(12-2)²+(2-2)²

S₁ = √(10)²+(0)²

S₁ = √100

S₁ = 10

For the coordinate (2, 2) , (17, 7)

S₂ = √(7-2)²+(17-2)²

S₂ = √(5)²+(15)²

S₂ = √25+225

S₂ = √250

S₂ = 15.8

For the coordinate (2, 12) , (17, 7)

S₃ = √(7-12)²+(17-2)²

S₃ = √(-5)²+(15)²

S₃ = √25+225

S₃ = √250

S₃ = 15.8

Perimeter of sign A = S₁+S₂+S₃

Perimeter of sign A = 10+15.8+15.8

Perimeter of sign A = 41.6

FOR SIGN B with coordinate of vertices (4,4),(11, 19) and (18, 4)

For the coordinate (4, 4) , (11, 19)

S₁ = √(19-4)²+(11-4)²

S₁ = √(15)²+(7)²

S₁ = √225+49

S₁ = 16.6

For the coordinate (4, 4) , (18, 4)

S₂ = √(4-4)²+(18-4)²

S₂ = √(0)²+(14)²

S₂ = √196

S₂ = 14

For the coordinate (11, 19) , (18, 4)

S₃ = √(4-19)²+(18-11)²

S₃ = √(-15)²+(7)²

S₃ = √225+49

S₃ = 16.6

Perimeter of sign B = S₁+S₂+S₃

Perimeter of sign B = 14+16.6+16.6

Perimeter of sign B = 47.2

FOR SIGN C with coordinate of vertices (4, 8), (24, 1) , and (24, 15)

For the coordinate (4, 8) , (24, 1)

S₁ = √(1-8)²+(24-4)²

S₁ = √(-7)²+(20)²

S₁ = √49+400

S₁ = 21.2

For the coordinate (4, 8) , (24, 15)

S₂ = √(15-8)²+(24-4)²

S₂ = √(7)²+(20)²

S₂ = √49+400

S₂ = 21.2

For the coordinate (24, 1) , (24, 15)

S₃ = √(15-1)²+(24-24)²

S₃ = √(14)²+(0)²

S₃ = √196+0

S₃ = 14

Perimeter of sign C = S₁+S₂+S₃

Perimeter of sign C = 14+21.2+21.2

Perimeter of sign C = 56.4

Arranging in order from largest to smallest perimeter, Sign C(56.4), Sign B (47.2), sign A (41.6)

The class can contain at most 28 students.

The length of a rectangle is 6 inches longer than the width. The perimeter of the rectangle is eight times the width. What is the width of the rectangle?

Answers

L = w+6
Perimeter = L + W
Substitute eqn 1 into 2
Perimeter = 2W + 6
Perimeter also = 8w
8w = 2W + 6
6w = 6
W = 1

Answer:

The width is 3 inches.

Step-by-step explanation:

First, let's identify our variables.

L=Length

W=Width

P=Perimeter

P=2W+2L

We know that L=W+6

We can substitute L for W+6, and we can substitute P for 8W, which gives us the equation:

8W=2W+2(w+6)

If you go through all the steps to isolate the variable W, you'll end up with W=3

a car uses 57 liters of gasoline for every 644 kilometers traveled. it takes 8 hours to use all the gasoline in the tank. what is the average speed of the car during the trip?

Answers

Answer:

80.5 kilometers/h

Step-by-step explanation:

S=80.5km/h

D644

T8 hours

The average speed of the car during the trip given the gasoline used per kilometer is 80.50 km/h.

What is the average speed?

Average speed is the total distance travelled per time. It is used to determine the total distance per time.

Average speed = total distance / total time

644 / 8 = 80.50 km/h.

How do you solve 2+x=-7

Answers

Answer:

x = -9

Step-by-step explanation:

Step 1: Write equation

2 + x = -7

Step 2: Solve for x

Subtract 2 on both sides: x = -9

Step 3: Check

Plug in x to verify it's a solution.

Substitute: 2 - 9 = -7Subtract: -7 = -7
In order to solve this linear equation, we need to group all the variable terms on one side, and all the constant terms on the other side of the equation. In our example,
- term 2, will be moved to the right side.
Notice that a term changes sign when it 'moves' from one side of the equation to the other.
Therefore, the answer is x=-9

D) there is not enough information to determine which vehicle is traveling at a greater speed

Answers

Answer:  A) vehicle 1 is traveling at greater speed

========================================================

Explanation:

Let's find the slope of the graph

m = (y2-y1)/(x2-x1)

m = (120-80)/(3-2)

m = 40/1

m = 40

Each time x goes up by 1, y goes up by 40.

Vehicle 1 travels 40 miles for each hour, ie, its speed is 40 mph.

-------------

Now find the slope of the table

m = (y2-y1)/(x2-x1)

m = (240-150)/(8-5)

m = 90/3

m = 30

Vehicle 2's speed is 30 mph.

We see that Vehicle 1 is traveling 10 mph faster compared to Vehicle 2.
