Answer:

c) 78 plants

Step-by-step explanation:

The total required is,

→ x = 143/11

→ [ x = 13 ]

Then number grew into plants,

→ 6 × x

→ 6 × 13

→ 78 plants

Hence, the option (c) is correct.

Answer: 78

Step-by-step explanation: 143 /11=13x6=78

Answer: 28.6%

Step-by-step explanation:

To calculate the percent error:

1) Subtract the estimated amount by the actual amount

45-35=10

2) Divide the answer by the actual amount

10/35=0.2857

3) Multiply the answer by 100 to get the percent error

0.2857×100=28.57

Rounded that equals 28.6%

Answer: hope this helps ♡

The percent error for the park sign's estimate is 29%.

Step-by-step explanation:

45 - 35 = 10

(10 out of 35 because it's the actual amount)

10 of 35 in percentage:

(10 ÷ 35) × 100 =

0.28571..... × 100 =

28.5714.....%  ≈  29%

Answer:

  see attachment

Step-by-step explanation:

To work these, you need a pencil (with a fairly sharp point) and a compass or pair of dividers (a compass-like tool with two points, instead of a point and a pencil).

In the attached, the blue segment represents the compass set to the length of segment 'a'. The red segment represents the compass set to the length of segment 'b', and the green segment represents the compass set to the length of segment 'c'.

When the segments are shown end-to-end, it means you mark off that length on the line, then mark off the next length starting at the end of the first one. When the segments are shown overlapping, it means you mark one of the segments in the reverse direction (you subtract its length).

You may find it helpful to use your pencil to mark a starting point on the target line. If you use a compass, a small arc across the target line at the end of the segment length can help you locate the start of the next segment length.

__

(1) The length of segment 'b' is added to the length of segment 'a'. This is not different in concept from adding numbers on a number line.

(2) The length of segment 'b' is made to overlap the end of segment 'a', so that the end points of the two segments are the same point. This subtracts the length of 'b' from that of 'a', so the length 'a-b' is the length from the left end of 'a' to the left end of 'b' in the configuration shown.

(3) You get the length '2b' by appending the length of 'b' to itself.

(4) All three lengths are appended to each other here.

(5) As before, you get 2b by appending 'b' to itself. You subtract 'c' by backtracking over the previous length, as in part (2).

__

You will get best results if you use this (attachment) as a guide. The line segments drawn are only eyeball approximations of the segments on your page, and their placement end-to-end is not as precise as you can make it with your compass.

Answer:

  $3785.53

Step-by-step explanation:

You want the interest amount due at the end of 8 years on a $5000 loan at 7.3% compounded annually.

The amount due is multiplied by (1 +0.073) each year. After 8 years, the amount due will be ...

  5000(1.073^8) ≈ 8785.53

Of that, 5000 is the principal amount, so the remainder is interest.

  interest = $8785.53 -5000

  interest = $3785.53

Becky will have to pay $3785.53 in interest.

Answer:

\(43/100\)

Step-by-step explanation:

First, make both of the denominators into 100.

Then, 3/10 would be 30/100.

Finally, you can add them to get 43/100.

Answer:

30%

Step-by-step explanation:

\(\frac{3}{10}\) of the shape is shaded.

3/10 = 0.3          0.3 * 100 = 30

so 3/10 is 30% as a percentage.

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Answer:

Step-by-step explanation:

Givens

The triangle is x

The square is y

Left side

x + 3y is the weight

Right side

4x + y is the weight.

The weights are equal because the hanger is balanced.

Balance equation

x + 3y = 4x + y                 Subtract x from both sides

x-x + 3y = 4x-x + y           Combine

3y = 3x + y                       Subtract y from both sides

3y - y = 3x + y - y             Combine

2y = 3x

Answer

2y = 3x

Answer:

  x +3y = 4x +y

Step-by-step explanation:

A hanger diagram like this is intended to show you that the total weight on the left side is equal to the total weight on the right side.

__

The left side shows 1 triangle and 3 squares. x and y are defined as the weights of the triangle and square, respectively, so the weight on the left side can be represented as ...

  x + 3y

The four triangles and 1 square on the right can have their total weight represented as ...

  4x +y

The intent of the diagram is to show that the left-side weight is equal to the right-side weight. That equality can be written as ...

  x +3y = 4x +y

_____

Additional comment

This problem is not asking for any sort of "solution" or relationship between x and y. We could find such a relationship by solving the equation for y:

  x +2y = 4x . . . . subtract y from both sides

  2y = 3x . . . . . . . subtract x from both sides

  y = (3/2)x . . . . . divide by the coefficient of y

This tells you that the hanger will only be balanced if the weight of a square is half-again as much as the weight of a triangle.
