Answer:

15 meters

Step-by-step explanation:

The diagram of the problem is attached below in the first image.

Chords KM and LN (which is the diameter) intersect at X.

Theorem: If the diameter is perpendicular to a chord, it bisects the chord.

Therefore:

LN divides KM into equal parts of 6 meters,

Applying the theorem of intersecting chords:

KX*XM = LX*XN

6*6=3*XN

3*XN=36

XN=12

Next, we find the length of the diameter LN

LN=LX+XN

=3+12

=15 meters

The diameter of the completed circle is 15 meters.

Answer: 42%

Step-by-step explanation:

First step is to add all the known values ( 21, 25, 12). You get 58. Considering it is out of 100, all the known values are 58%

Next: Subtract 58 from 100. You get 42

Again, since it is out of 100, it is 42%

The answer is 42%

Answer: The expression would be 2b+7

Step-by-step explanation:

b will be the number of blue beads for the bracelet.

The number of red beads will be represented as b + 7.

Determine the expression for the total number of beads.

Then we can written it as,

= b + (b +7)

= 2b + 7.

Answer:

48 mm squared

Step-by-step explanation:

divide the shape into 3 parts- left square, middle joining rectangle, and right rectangle

a) the right most square has an area of 4 by 4 ie 16 mm sq.

b) the middle adjoining rectangle and length of 2 mm and breadth of 1mm making its area 2mm sq.

c) the right rectangle has height 5 mm nad breadth 6mm making the area 30 mm sq.

adding parts a b and c the total area is 16+2+30 = 48 mm squared

Answer:

48 square mm

Step-by-step explanation:

see attached image

We have 3 rectangles now.

16+2+30

=48

So, the area is 48 square mm.

Answer:

draw a line that makes a triangle and rectangle.

hypotenuse= 30

3k-4k-5k triangle

18-24-30

so the short part of triangle is 18 cm

10+10+18+24+30 equals 92

sorry for language I am not familiar with English

the perimeter of this shape is

24+10+10+30+\(\sqrt{30^{2} -24^{2} }\) = 92 cm

Answer:

b. 2/3

Step-by-step explanation:

First, I multiplied all of the values to each other, to get the area^3 of the box.

With my answer, 4.73925, I used a longer method, and divided my answer by each answer displayed.

a-4.73925/1/3=12.21775

b-4.73925/2/3=7.108875

c-4.73925/1/2=9.4785

d-4.73925/1=4.73925

I didnt use the full answer from when I multiplied all the answers together, so the answer will be just hardly off a whole number. So, b should be the answer.

If the answers were side lengths, read below

First, I multiplied all of the values to eachother, to get the area^3 of the box.

With my answer, 4.73925, I used a longer method, and divided my answer by each answer displayed, after I cubed them.

a-1/3^3=1/27

b-2/3^3=8/27

c-1/2^3=1/8

d-1^3=1

Next, I divided 4.73925 by all of the values listed above.

a-4.73925/1/27=127.9595

b-4.73925/8/27=15.9949

c-4.73925/1/8=37.914

d-4.73925/1=4.73925

After I had completed this process, b is still the closest to a whole number, So, b is my answer.

Answer:

Area of five squares = 1289.09 square units

Perimeter =  194.6 units

Step-by-step explanation:

Area of square and perimeter:

   First find the length of each square, then find the area of each square.

To find the area of five squares, add all the area of each square.

Side of square1 = 27 units

\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)

Area of square1 = 27*27 = 729 square units

Area of square2 = 18*18 = 324 square units

Area of square3 = 12*12 = 144 square units

Area of square4 = 8*8 = 64 square units

Area of square5 = 5.3*5.3 = 28.09 square units

Area of five squares = 729 + 324 + 144 + 64 +28.09

                                  = 1289.09 square units

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)

                                                         = 90 + 42 + 28 + 18.7 + 15.9

                                                          = 194.6 units

Answer:

$2.50

Step-by-step explanation:

Let's set up a proportion using the following setup.

price / pens = price / pens

We know that it costs $4.00 for 8 pens.

$4.00 / 8 pens = price / pens

We don't know how much it costs for 5 pens. Therefore, we can say it costs $x for 5 pens.

$4.00 / 8 pens = $x / 5 pens

4/8=x/5

We want to solve for x (the cost for 5 pens). Therefore, we must get x by itself on one side of the equation. x is being divided by 5. The inverse of division is multiplication, so multiply both sides of the equation by 5.

5*(4/8)=(x/5)*5

5*(4/8)=x

5*0.5=x

2.5=x

x= $2.50

Ivan should pay $2.50 for 5 pens.

Answer:

Step-by-step explanation:

Y-INTERCEPT: It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.

SLOPE:The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

Answer:

2.282 x 10^12

Step-by-step explanation:

So basically the question asks us to find the difference which means subtraction

5.482 x 10^12 - 3.2 × 10 ^12 =...

As 10^12 is multiplied by both values, you can cancel them

So, 5.482 - 3.2 =...

If you calculate it you will get 2.282

Don't forget to place back the x 10^12 we cancelled

So the answer will be 2.282 x 10^12

The difference between the two given numbers will be 2.282 x 10¹².

Numbers that are either too large or too little to be conveniently stated in decimal form can be expressed using scientific notation. It could be called scientific form.

A numerical indication of the operation of raising to a power that is placed above and to the right of a mathematical expression.

Given numbers are 5.482 x 10¹² and 3.2 x 10¹². The difference will be calculated as:-

Difference = 5.482 x 10¹² - 3.2 × 10¹²

Difference = ( 5.482 - 3.2 ) × 10¹²

Difference = 2.282 × 10¹²

Therefore, the difference between the two given numbers will be 2.282 x 10¹².
