Answer:

91.7 inches to 1 decimal place

Step-by-step explanation:

We will use Pythagoras's theorem to find the height of the pyramid.

The height of the Pyramid forms a right-angled triangle with half of the base and the slant height.

We can get half the length of the base by dividing the length of one side of the base = 20.4 by 2 = 10.2in

slant height = 92.3in

Therefore height = [tex]\sqrt{92.3^{2} -10.2^2} =91.73in[/tex]

The height of the pyramid is 91.73inches to 1 decimal place

Answer:

Step-by-step explanation:

Let all the measurements be in same unit.

200 cm = 2 m

2000 mm = 2 m

Let distance jumped by Jack = x m

Distance jumped by Jerzy = x + 2

Distance jumped by Abdullah = (x+ 2) + 2 = x + 4

Total = 12.69 m

x + x +2 +x +4 = 12.69

x +x + x + 2 + 4 = 12.69

         3x + 6      = 12.69

                  3x = 12.69 - 6

                 3x  = 6.69

                    x = 6.69/3

                    x = 2.23 m

distance jumped by Jack =2.23m

Distance jumped by Jerzy = 2.23 + 2 = 4.23 m

Distance jumped by Abdullah = 2.23 + 4 = 6.23 m

Answer: Neither

Step-by-step explanation:

For this to be paralell it would need to have the same slope. (They don't  have the same.) For this to perpandicular it would have to reciporcal  ( Ex: -2 reciporcal would -1/2 or 1/4 reciprocal would have to be 4)

Answer:

neither

Step-by-step explanation:

For two lines to be parallel, their slopes must be equal.

For two lines to be perpendicular, their slopes must have a product of -1. (The only exception is a vertical line and a horizontal line which are perpendicular, but the product of their slopes is not -1.)

When the equation of a line is written in the slope-intercept form,

y = mx + b,

m is the slope.

y = -2x + 4 has a slope of -2.

y = (1/4)x -2 has a slope of 1/4.

Clearly, -2 and 1/4 are not equal, so the lines are not parallel.

Now we find the product of the slopes.

(-2) * (1/4) = -2/4 = -1/2

The product of the slopes does not equal -1, so the lines are not perpendicular.

Answer: neither

Step-by-step explanation:

Answer:

angle 5 is 149

angle 8 is 31

Step-by-step explanation:

since angle three and five are diagonal from each other on opposite sides they will have the same measurements.  since angle eight is on the same side as angle five the total of the two angles has to equal 180

The picture is not clear... the Question has got cut at the sides .... please take the picture properly and the post the Question again... please

[tex]\\\\\huge\underline\mathbb\pink{ANSWER:}\\\\[/tex]

No they are not unequal... i. e. the two wires A and B are equal .

[tex]\frac{1}{3}[/tex] of A = [tex]\frac{1}{3}[/tex] of B

=> [tex]\frac{3}{3}[/tex] × A = B

=> 1 × A = B

=> A = B

:. The length of A = the length of B .

Answer:

77r - 2077

Step-by-step explanation:

To find the the sum of (23m−34)( 3 2 ​ m− 4 3 ​ ) and (−16m−r)(− 6 1 ​ m−r)

First open the bracket

23m × 32m - 23m × 43 - 34 × 32m + 34 × 43

736m^2 - 989m - 1088m + 1462

736m^2 - 2077m + 1462

Open the second bracket

16m × 61m + 16m × r + r × 61m + r × r

976m^2 + 16mr + 61mr + r^2

976m^2 + 77mr + r^2

Adding both equations together

736m^2 - 2077m + 1462 + 976m^2 + 77mr + r^2

1712m^2 + 77mr - 2077m + 1462 + r^2

1712m^2 + m( 77r - 2077 ) + 1462 + r^2

Therefore The coefficient of m is 77r - 2077

Answer:

4in 5in and 8in (in that order)

Step-by-step explanation:

You measure Hight at the place where it makes a right angle (for these look at the dotted line and the number labeling it)

Answer:

1. 4 inches

2. 5 inches

3. 8 inches

Step-by-step explanation:

The heights are labelled.

Answer:

10 easy levels and 10 difficult levels

Step-by-step explanation:

Given data

let the number of easy levels be x

and the number of difficult levels be y

so

x+y= 20----------1

and

3x+5y= 80------2

from 1

x=20-y

put this in 2

3(20-y)+5y= 80

60-3y+5y=80

2y=80-60

2y=20

y= 20/2

y= 10

put y= 10 in 1

x+10=20

x=20-10

x= 10

Hence Kiran played 10 easy levels and 10 difficult levels

Answer:

5a/3b

Step-by-step explanation:

Step-by-step explanation:

value of b is 73 (reason : sum of triangles)

a= 34 ( reason:180-73-73=34)

Answer: 73+73=146, 180-146= 34°

Step-by-step explanation:

b is parallel to 73, b= 73°

c = 34°

Answer:

$13.5

Step-by-step explanation:

Given data

We are given that the tax per CD is  $1.30

Hence for the 3 CDs the total tax = 3*1.3= $3.9

Also, the cost of the three CDs before tax = 44.4-3.9

=$40.5

Hence the cost of each CD before tax is

=40.5/3

=$13.5

$3,600

Step-by-step explanation:

You'd multiply 1,500 with .20 which equals 300. You'd then multiply 300 and 12 together to make $3,600.

Answer:

68.55

Step-by-step explanation:

C= 2πr

C=2 x 3.14 x 7.5 = 47.1 (Divide by 2 for half circle)

47.1 ÷ 2 = 23.55 + 15 + 15 + 15 = 68.55

Answer:

48

Step-by-step explanation:

Multiply 0.2 × 240 = 48.

It's a very biased coin, so the outcome will be considerably less than the 120 we would expect from a fair coin.

Answer:

x=42°

Step-by-step explanation:

We know that 2 of the legs are congruent, so the angles opposite them will be congruent.

The angles of a triangle add up to 180°

This can be represented by [tex]96+2x=180[/tex]

[tex]2x=84[/tex]

[tex]x=42[/tex]

Hope this helps :-)

Answer: 42 degrees

Step-by-step explanation: Since this is an isosceles triangle, your remaining two angles will be equal

There are 180 degrees in any triangle

Since you have already used 96 degrees, you must subtract to find what is remaining

180-96=84

Since your remaining two angles are equal, you can half 84 to find your answer

84/2=42

Both x and your one remaining angle should be 42

X=42
