The top of a ladder rests on the side of the house at a height of 15 feet. If the ladder is 16 feet, what is the length from the base of the ladder to the house? PLZ HELP

Answer:

Perimeter of rectangle is 16 cm and the area of square is 1 cm^2

Step-by-step explanation:

Here, we want to get the perimeter of rectangle and area of square

From the question, the rectangle has 2 rows of 6 squares each; So we have the length as 2 cm and the width as 6 * 1 cm = 6 cm

So the rectangle is 6 cm by 2 cm

The perimeter of a rectangle is 2(l + b)

so, we have 2(6 + 2) = 2(8) = 16 cm

The area of the square is simply the side length raised to the power of 2

we have this as 1^2 = 1 cm^2

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:

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:

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

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.

Here, we have,

John wants to know his class’s favourite TV show, so he surveys all of the boys.

now, we get,

The sample will be biased.

A number we don't know

Step-by-step explanation:

Answer:

C.19 mi

D. 19 StartRoot 6 EndRoot mi

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:

$5,500

Step-by-step explanation:

Steve is Darrlyn house for $360,000

Steve loan amount $275,000

He agreed to pay 2 points at closing

Therefore the amount steve will pay for points can be calculated as follow

= 275,000 × 2/100

= 275,000 × 0.02

= 5,500

Hence Steve will pay $5,500

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:

[tex]\text{(a) }\$10,080,\\\text{(b) }\$11,289.60,[/tex]

Step-by-step explanation:

Since interest is compounded annually, the amount of money the account has after [tex]n[/tex] years is given by [tex]y=9,000\cdot 1.12^n[/tex].

(a) After 1 year, [tex]n=1[/tex]:

[tex]9,000\cdot 1.12^1=\boxed{\$10,080}[/tex]

(b) After 2 years, [tex]n=2[/tex]:

[tex]9,000\cdot 1.12^2=\boxed{\$11,289.60}[/tex]

20.0 mL of 5.0 M HCl solution contains

0.0200 L * 5.0 M = 0.10 mol

of HCl.

Mixing the HCl and NaOH solutions results in

HCl + NaOH ==> NaCl + H2O

which is to say 0.10 mol of HCl reacts with 0.10 mol of NaOH. If only 10.0 mL of NaOH solution is required, then its molarity x is such that

0.0100 L * x M = 0.10 mol   =>   x = 10. M

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. :)

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:

£56.25

Step-by-step explanation:

Number of guest = 57

The 20cm cake :

Can serve 12 people and cost £13.50

The 25cm cake :

Can serve 20 people and cost £18.75

Since the cake has to be the same size, the only one particular size would have to be purchased ;

For the 20cm cake ; 57/12 = 4.75 = five 20cm cakes ;

£13.50 * 5 = £67.50

For 25cm cake ; 57 / 20 = 2.85 = three 25cm cakes

£18.75 * 3 = £56.25

£56.25 is lower ; hence, amount he'll have to pay is £56.25

Step-by-step explanation:

[tex] {15}^{2} = {12}^{2} + {x }^{2} \\ 255 - 144 = {x}^{2} \\ 81 = {x}^{2} \\ \sqrt{81 } = x \\ 9 = x[/tex]
