DeVondrea stacked 2
quarters and a nickel on top
of each other. What is the
thickness of the stack of
coins?

Step-by-step explanation:

Given :-

The length of the garden 8m greater than 2 times the width.

Area of the garden is 280 m²

Let us consider the length as x and width as y.

Sp, we can day length as :-

x = 8 + 2y ---(1)

Now, we know that:-

Area of Rectangle = Length × Breadth

280 = x * y

We can replace the value of x now,

280 = y × ( 8 + 2y)

280 = 8y + 2y²

2y² + 8y - 280 = 0

y² + 4y - 140 = 0

Factorise it.

(y -10)(y + 14)

Cancelling -ve value, we get the width as 10 metres.

Hope it helps :)

Answer:

Step-by-step explanation:

Width = w

Length = 2w + 8

Area of rectangular garden = 280 square meter

length * width = 280

(2w + 8 ) *w = 280

2w * w + 8*w = 280

2w² + 8w = 280

2w² + 8w - 280 = 0

Divide the whole equation by 2

w² + 4w - 140 = 0      

w² + 14w - 10w - 14 *10 = 0

w(w + 14) - 10(w + 14) = 0

(w + 14)(w - 10)= 0

w - 10 = 0       {Ignore w + 14, as measurements will not be -ve}

w = 10 m

l = 2*10 +8

= 20 +8

l  = 28 m

Answer:

b. False

Step-by-step explanation:

The law of large numbers, in statistics, says that the experimental average found in a large number of trials should be very close to the theoretical probability. It does not say anything about distribution. So the answer to this question is False, which is given by option b.

Answer:

The original price of the shoes was $90.

Step-by-step explanation:

25% off means the price Joe paid for it is 75% of the original price.

Set up an equation:

75/100 = 67.50/x

Cross multiply

75 × x = 100 × 67.50

75x = 6750

x = 90

Check our work:

First solve for 25% off of 90 (our answer).

25% = 0.25

90 × 0.25 = 22.50

Next, subtract the discount from 90.

90 - 22.50 = 67.50

67.50 was what Joe paid so this is correct.

Step-by-step explanation:

Answer: 9.04

Step-by-step explanation:

Answer:

no

Step-by-step explanation:

using Pythagoreans theorem

a^2+b^2=c^2

3^2+5^2≈6^2

9+15=34

not 36 so no

Here, It is stated that the triangle having sides 3, 5 and 6 respectively. So, we have to prove that whether the given triangle is right angled triangle or not.

For That :

We will be using the Pythagoras Theorem

According to the Pythagoras Theorem , the sum of the square of Base side and perpendicular side is equal to the square of the longest side i.e, hypotenuse.

Pythagoras Theorem :

⠀⠀⠀⠀⠀⠀[tex]{\bullet \: {\boxed{\sf {AC^{2} = AB^{2} + BC^{2}}}}} \\ \\ [/tex]

So, here the longest side is Side A of measurement 6.

So, Now

Applying Pythagoras Theorem in it, we get :

The three sides , so let's plug the values in the formula :-

[tex]\dashrightarrow\:\:\sf AC^{2} = AB^{2} + BC^{2}\\ \\[/tex]

[tex]\dashrightarrow\:\:\sf 6^{2} = 3^{2} + 5^{2}\\ \\[/tex]

[tex]\dashrightarrow\:\:\sf 36 = 9 + 5^{2}\\ \\[/tex]

[tex]\dashrightarrow\:\:\sf 36 = 9 + 25 \\ \\[/tex]

[tex]\dashrightarrow\:\:\sf 36 \neq 34 \\ \\[/tex]

[tex]{\underline{\sf {L.H.S \neq R.H.S}}} \\ [/tex]

If in a triangle, the square of the hypotenuse is not equal to the sum of the squares of the other two sides, then the given triangle and doesn't satisfy pythagoras theorem. Hence, Its not a right angled triangle.

Answer:

Cos Y = 12/13

Step-by-step explanation:

Recall, SOHCAHTOA.

Cos Y = Adjacent/Hypotenuse

Reference angle = Y

Adjacent = 12

Hypotenuse = 13

Therefore:

Cos Y = 12/13

She need 3 packs of balloons

Answer:

616 cm^2

Step-by-step explanation:

Steps to derive the answer

1. we are going to first determine the radius from the circumference

2. we would calculate the area

Circumference of a circle = 2nr

n = 22/7

r = radius

88 = 2 x 22/7 x r

Divide both sides of the equation by 2 x 7/22

r = 14

Area of a circle = nr^2

3.14 x 14^2 = 616 cm^2

Answer:

y = -2x + 5

Step-by-step explanation:

Points on the path: (0, 5) and (1, 3)

Slope:

m=(y2-y1)/(x2-x1)

m=(3-5)/(1-0)

m= (-2)/1

m= -2

Slope-intercept:

y - y1 = m(x - x1)

y - 5 = -2(x - 0)

y - 5 = -2x

y = -2x + 5

Answer:

The height on the map is of 12 inches.

Step-by-step explanation:

Scale of 1 inch:300 meters

This means that each inch on the map represents 300 meters of real height.

If the actual height of one of those mountains is 3,600 meters, what is its height on the map?​

Using proportions, by a rule of three:

1 inch - 300 meters

x inches - 3600 meters

Applying cross multiplication:

[tex]300x = 3600[/tex]

[tex]x = \frac{3600}{300}[/tex]

[tex]x = 12[/tex]

The height on the map is of 12 inches.

Answer:

y = 658.3 ft

Step-by-step explanation:

Angle of depression = angle of elevation = 28° (alternate angles are congruent)

Reference angle = 28°

Side length opposite to reference angle = 350 ft

Adjacent = y

Apply trigonometric function, TOA:

Tan 28 = Opp/Adj

Tan 28 = 350/y

y*Tan 28 = 350

y = 350/Tan 28

y = 658.254263 ≈ 658.3 ft (nearest tenth)
