The length of a rectangle is 4 meters less than three times its width. If the perimeter of the rectangle is 48 meters, then what is the value of the length (in meters)?

Answers

Answer 1

Answer:

7

Step-by-step explanation:

Think about it visually. 3x-4 is the length and x is the width. Since a rectangle has 2 parralel and equal sides, it's just double those. The equation is 8x-8=48. 48 is the total as given in the problem.

8x-8=48

8x=56

x=7

The width is 7

If (x,83) is a solution to the equation 2y=1/2(98x+38), find x.

Answers

Answer:

X= 2y/49 - 19/49

Answer:

because (x; 83) is a solution to the equation

2y=1/2(98x+38)

=> 2.83 = 1/2(98x + 38)

<=> 4.83 = 98x + 38

<=> 332 = 98x + 38

<=> 98x = 294

<=> x = 3

Step-by-step explanation:

Use the distributive property to get rid of the parentheses.

-4x + 10 +x is correct, but the x's can be combined.

(-4x + x) + 10 = -3x + 10

Answers

Answer:

A. It is symmetric and has no gaps.

Step-by-step explanation:

Given

See attachment for dot plot

Required

Select the true statement

From the attached plot, we can see that

The plot is bell shaped (by tracing the number of dots on each dataset) There is no gap between each dataset (from 4 to 7)

Since (1) all bell shaped distribution are symmetric and (2) there is no gap between the dataset, then (a) is correct.

The spinner is shown has eight congruent sides the spinner is spun 200 times. What is a reasonable prediction for the number of times the spinner will land on 2 or 3

Answers

Answer:

50 times

Step-by-step explanation:

Total number of faces = total possible outcomes = 8

Number of 2 or 3 on spinner = required outcome = 2

Probability of obtaining a 2 or 3 = required outcome / Total possible outcomes

P(2 or 3) = 2 / 8 = 1/ 4

From 200 ; prediction for the number of 2 or 3

1/4 * 200

= 50 times

Find the IQR (interquartile range).
19, 21, 18, 17, 18, 22,46

Answers

Answer:

4.

Step-by-step explanation:

Step 1: Formula.

[tex]IQR=Q3-Q1[/tex]

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

Step 2: Explain/define.

The interquartile range is the difference between quartile 3 and quartile 1.Quartile 1 is the median of the upper half of a data set.Quartile 3 is the median of the lower half of a data set.The median is the 'middle value.'

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

Step 3: Order/arrange.

In order to find the median, you must first put the numbers in numerical order.

19, 21, 18, 17, 18, 22, 46

               ↓

17, 18, 18, 19, 21, 22, 46

The lower half of the data set, not including the median of the whole data set, is 17, 18, and 18.

The upper half of the data set is 21, 22, and 46.

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

Step 4: Solve.

17, 18, 1821, 22, 36

Next, we find the medians of both sets.

The median of the lower half is 18 (Q1).

The median of the upper half is 22 (Q3).

Lastly, we subtract Q3 from Q1.

[tex]22-18=4.[/tex]

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

Step 5: Conclude.

I, therefore, believe the interquartile range of this data set is 4.

Which expression is not equivalent to 8 + (n - 4)?

n + 4

12 + n

(8 - 4) + n

Answers

I think the answer is n+4 because the 8 wasn’t added or subtracted.

Answer:

12+n

Step-by-step explanation:

Hi!

8+n-4 = n+4

n+4 = n+4 (Can not be simplified).

(8+n)-4 = n+4

12+n = 12+n (Can not be simplified).

(8-4)+n = n+4

So the answer would be 12+n because it does not equal n+4.

ok ik but i need help with this i think i got it tho -275=2x -50

Answers

Answer:

-112.5

Step-by-step explanation:

2x - 50 = -275

2x = -225

x = - 112.5

Answer:

x = -225/2 (or) -112.5

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ -275 = 2x - 50

Then the value of x will be,

→ -275 = 2x - 50

→ 2x - 50 = -275

→ 2x = -275 + 50

→ 2x = -225

→ x = -225/2

→ [ x = -112.5 ]

Hence, value of x is -112.5.

Three of the paths in a city park form a right triangle, as shown on the map. Each unit on the map represents 10 meters. The city plans to plant trees along these paths.

Answers

The perimeter of the triangle is 188.1 m

How to find the perimeter of the triangle?

The perimeter of a triangle can be determined by adding the three lengths of the triangle.

From the image, the coordinates of vertices of the triangle are:

(-3, 3), (-3, -2) and (3, 3)

distance between (-3, 3) and (-3, -2) is:

3-(-2) = 5  (we use y coordinates only because x are the same)

       = 50 m  (Each unit on the map represents 10 meters)

distance between (-3, 3) and (3, 3) is:

3-(-3) = 6    (we use x coordinates only because y are the same)

       = 60 m

distance between (3, 3) and (-3, -2) is:

= √(50² + 60²)     (Pythagoras)

= 78. 1 m

Perimeter = 50 + 60 + 78.1 = 188.1 m

Joseph's uncle wants to put shingles on the outside walls and solar panel the roof of his barn shown at the right. It costs $2.50 for each square meter of shingles, while solar panals cost $4.00 per square meter. How much will this project cost?

Answers

Answer:

The answer is below

Step-by-step explanation:

From the image attached, the measurement of the roof is 5 m by 9 m on  both sides. Hence:

Area of roof = 2 (5 * 9) = 90 m²

Since solar panels cost $4.00 per square meter, therefore:

Cost of solar panels = $4.00 per square meter * 90 m² = $360

The area of the front wall of the barn = (8 m * 7 m) + (1/2 * 8 m * 3 m) - (4 m * 4 m) = 52 m²

The area of the back wall of the barn = (8 m * 7 m) + (1/2 * 8 m * 3 m) = 68 m²

Area of each side wall of barn = 9 m * 7 m = 63 m²

Total area of wall = 52 m² + 68 m² + (2 * 63 m²) = 246 m²

Cost of shingles = $2.50 for each square meter * 246 m² = $615

Total cost of project = $615 + $360 = $975

Answers

Answer:

250

Step-by-step explanation:

she gave 5 oranges to her husband .

What is an Equation ?

A statement that links two expressions with an equal sign is called an Equation.

It is given that

Aunt Mansah bought 100 oranges

she bought 4 oranges for 20p

1 is bought at 5p

Let x be the number of oranges she gave to her husband

The remaining oranges were sold at 5 for 40p

1 is sold at 8p

Profit = £2.60

The given data can be used to form equation and solving them will give desired answers

1 pound = 100 pence

( 100 - x) * 8 - ( 100) * 5 = 2.60 * 100

800 - 8x -500 = 260

-8x +300 = 260

8x = 40

x = 5

Therefore she gave 5 oranges to her husband .
