Answer:

<h2>37.68</h2>

Step-by-step explanation:

<em>The length of a piece of ribbon glued around the edge of the lid is equal to the circumference of the lid. First, use the formula to find the approximate circumference of one jar lid.</em>

<em />

<em>Next, since Bianca wants to glue ribbon around the edge of both jar lids, multiply this length by two.</em>

What is the area of this trapezoid?
Pie

Area of a Trapezoid, A = [(a+b)/2] · h

Where,

a and b are the respective bases of the trapezoid

h is the height of the trapezoid

 

a = 10

b = 7 + 10 + 10 = 24

h = 9

 

A = [(a+b)/2] · h

A = [(10 + 24)/2] · 9

A = [(34)/2] * 9

A = 17 * 9

A = 153 Units²

Solve for x: 7 over 8 minus 1 over x equals 3 over 4.
photoshop1234 [79]
Hi!

Let's write the equation in number form first.

7 over 8
7/8

minus 1
7/8 - 1

over x
7/8 - 1/x

equals 3
7/8 - 1/x = 3

over 4
7/8 - 1/x = 3/4

Now to find the value, let's put each option as the value for x.

A. x = 1
7/8 - 1/1 = 3/4
7/8 - 1 = 3/4
0.875 - 1 = 0.75
-0.125 = 0.75
This is wrong.

B. x = 2
7/8 - 1/2 = 3/4
7/8 - 0.5 = 3/4
0.875 - 0.5 = 0.75
0.375 = 0.75
This is wrong.

C. x = 4
7/8 - 1/4 = 3/4
7/8 - 0.25 = 3/4
0.875 - 0.25 = 0.75
0.625 = 0.75
This is wrong.

D. x = 8
7/8 - 1/8 = 3/4
7/8 - 0.125 = 3/4
0.875 - 0.125 = 0.75
0.75 = 0.75
This is correct!

The answer is d. x = 8

Hope this helps! :)

What is the volume of a hollow ball whose other radius is 200m and inner radius of 100m? What is the mass if it is iron?
kati45 [8]

Solution :

Volume of ball = Volume of outer ball - Volume of inner ball

V = \dfrac{4\pi R^3}{3} - \dfrac{4 \pi r^3}{3}\\\\V = \dfrac{4\pi}{3}( R^3 - r^3 )\\\\V = \dfrac{4\pi}{3}( 200^3 - 100^3 )\\\\V = \dfrac{4\pi}{3}(2^3 - 1^3) \times 10^6\\\\V = 2.93 \times 10^7 \ m^3

Now, density of iron is, d = 7300 kg/m³.

So, mass of iron ball is :

m = d\times V\\\\m = 7300\times 2.93 \times 10^7 \ kg\\\\m =  2.14 \times 10^{11}\ kg

Hence, this is the required solution.

ou are standing 45 meters from the base of the Empire State Building. You estimate that the angle of elevation to the top of the
svetlana [45]

Answer:

443.2m

Step-by-step explanation:

Given in the question that,

distance from building to me = 45m

angle of elevation = 82°

building is 123 m + x m high

If we closely observe then this situation make a right angle triangle and we will use trigonometry identity to solve the question.

Step 1

tan(82) = y / 45

y = 45tan(82)

y = 320.2 m

Step 2

Hence the height of building is y + 123m. So, plug the value of y in this

320.2 + 123 = 443.2

Elibri has a spinner like the one that follow, where 3/5 of the spinner is red, 1/5 is blue and 1/5 is yellow.
slamgirl [31]

The expected value is the sum of values multiplied by their probabilities.

... 15×(1/5+1/5) + 5×(3/5) = 6+3 = 9

The expected value of a single spin is 9 points.
