Answer:

6.2

Step-by-step explanation:

P - 4.2 =2

we have to no separate the variables and constants

so , when we move 4.2 to the other side ( other side of 2) it will be something like this

p = 2+4.2

as you can wee when we moved 4.2 to the other side the operation changed from ,minuus to plus sign .

now just do what it says

formula :

=p-4.2=2

=p = 2+4.2

= 2+ 4.2= 6.2

so,

p=6.2

write the formula , I think no need to write explanation

Answer:

40

Step-by-step explanation:

Let the numbers be 2x and 3x

Then their L.C.M. = 6x

BUT also their LCM=48

6x=48

x=48/6

x=8

So,

First number=2x=2x8=16

Second number=3x=3x8=24

The numbers are 16 and 24.

Hence required sum =(16+24)=40

So none of the options are correct

Answer:

Statement 4 is true.

Step-by-step explanation:

- Statement 1 is false because a rhombus has 4 equal sides with 2 pairs being parallel to each other.

- Statement 2 is false because a trapezoid usually has only 2 sides that are parallel while the other 2 are not parallel. Thus it has only a pair of parallel sides.

- A square must have all 4 sides equal. But rectangles don't have all 4 sides equal and so the statement is false.

- Rhombus has all 4 sides equal and where it has all interior angles as right angles, it is called a square. Thus, some rhombus have all 4 interior angles as right angles.

Answer:

28800 square feet

Step-by-step explanation:

We solve this using the Heron's formula

Area of a Triangle = √s(s - a)(s - b)(s - c)

s = a + b + c/2

s = 100 + 580 + 600/2 = 640

Area of the land(Triangle) = √640 × (640 - 100)(640 - 580)(640 - 600)

= √640 × (540) ×( 60) × (40)

= √(829440000)

= 28800 square feet

Therefore, the approximate the area of the land is 28800 square feet.

Answer:

Toney buys the coat for $ 14.8.

Step-by-step explanation:

Cost of coat =$ 22

Mark up by 75 %

discount = 10 %

Let toney pay $ R for the coat.

So, according to the question

R + 75 % R = 1.75 R

Now the cost is

1.75 R - 15 % of 1.75 R = 22

1.75 R - 0.2625 R = 22

R = 14.8

So, he buy the coat for $ 14.8.

d = √(3h/2)

Where,

d = distance they can see in miles h = their eye-level height in feet

Pam:

h = 324 ft

d = √(3h/2)

d = √{(3 * 324)/2}

= √972/2

= √486

= √(81 * 6)

= √81 * √6

= 9√6 mi

Adam:

h = 400 ft

d = √(3h/2)

d = √{(3 * 400)/2}

= √1200/2

= √600

= √(100 * 6)

= √100 * √6

= 10√6 mi

How much farther can Adam see to the horizon?

Adam - Pam

= 10√6 - 9√6

= √6 mi

Answer: [tex]93,\ 34^{\circ}[/tex]

Step-by-step explanation:

Given

For figure (i) both triangles are congruent

[tex]\therefore 8x-27=4x+33\\\Rightarrow 8x-4x=33+27\\\Rightarrow 4x=60\\\Rightarrow x=15[/tex]

[tex]\Rightarrow PQ=8x-27\\\Rightarrow PQ=93[/tex]

For figure (ii)

Two triangles WXZ and WZY are congruent

[tex]\therefore 9x-28=5x-8\\\Rightarrow 4x=20\\\Rightarrow x=5^{\circ}\\\Rightarrow \angle YWX=2(9x-28)\\\Rightarrow \angle YWX=2(17)\\\Rightarrow \angle YWX=34^{\circ}[/tex]

Answer:

9/20

Step-by-step explanation:

After Bob eats 1/4 of the pie, he has 3/4 left. 2/5 of 3/4 is the same as (2/5)*(3/4) because "of" is used as multiplication in math. (2/5)*(3/4)=6/20, so he ate 6/20 of the pie. To get the answer, you need to solve 1-(1/4+6/20)=

1-(5/20+6/20)=20/20-11/20=9/20. I hope this helps and sorry if I made a mistake. :)

The sample will be biased.

What is bias?

Bias is a disproportionate weight in favor of or against an idea or thing, usually in a way that is closed-minded, prejudicial, or unfair. Biases can be innate or learned. People may develop biases for or against an individual, a group, or a belief. In science and engineering, a bias is a systematic error.

Answer:

2009.6 in²

Step-by-step explanation:

The surface area, SA of a cone is obtained using the formular :

SA = πr² + πrl

Where ; r = Radius = 20 inches ; l = slant height = 12 inches

SA = π*20² + π*20*12

SA = 400π + 240π

Take π = 3.14

SA = (400*3.14) + (240*3.14)

SA = 1256 + 753.6

SA = 2009.6 in²

Answer:

The slope is 3/2 and a point on the line is (-7,-4)

Step-by-step explanation:

Point slope form of a line is

y -y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line

y+4=-3/2(x+7)

y - -4 = 3/2 ( x - -7)

The slope is 3/2 and a point on the line is (-7,-4)
