Answer:

45.82 square inches

Step-by-step explanation:

Use the formula for the surface area of a sphere, A = 4[tex]\pi[/tex]r²

If the diameter is 3.82 inches, the radius is 1.91 inches.

Plug in 3.14 as [tex]\pi[/tex] and 1.91 as r, and solve:

A = 4[tex]\pi[/tex]r²

A = 4(3.14)(1.91²)

A = 45.82

So, approximately 45.82 square inches of material are needed.

=========================================

Work Shown:

a = 300 = first term

r = 60/300 = 0.2 = common ratio

We multiply each term by 0.2, aka 1/5, to get the next term.

Since -1 < r < 1 is true, we can use the infinite geometric sum formula below

S = a/(1-r)

S = 300/(1-0.2)

S = 300/0.8

S = 375

----------

As a sort of "check", we can add up partial sums like so

and so on. The idea is that each time we add on a new term, we should be getting closer and closer to 375. I put "check" in quotation marks because it's probably not the rigorous of checks possible. But it may give a good idea of what's going on.

----------

Side note: If the common ratio r was either r < -1 or r > 1, then the terms we add on would get larger and larger. This would mean we don't approach a single finite value with the infinite sum.

Answer:

a)    x = 2

b)    x = 4

Step-by-step explanation:

a = (b₁ + b₂)/2 * h

----------------------------

a)

48 = (10 + x)/2 * 8

Divide both sides by 8

6 = (10 + x)/2

multiply both sides by 2

12 = 10 + x

Subtract 10 from both sides

2 = x

x = 2

---------------------------------

b)

18 = (7 + 2)/2 * x

18 = 4.5 * x

divide both sides by 4.5

4 = x

x = 4

the answer is :C midsegment

Step-by-step explanation:

Answer:

[tex]\text{D. 36.64}[/tex]

Step-by-step explanation:

The Law of Sines is given by [tex]\frac{a}{\sin A}=\frac{b}{\sin B}=\frac{c}{\sin C}[/tex] and works for any triangle.

Therefore, we have the proportion:

[tex]\frac{c}{\sin 41.5^{\circ}}=\frac{37}{\sin 42^{\circ}},\\\\c=\frac{37\sin 41.5^{\circ}}{\sin 42^{\circ}}=36.6399945706\approx \boxed{36.64}[/tex]

Answer:

there are going to be 3 solutions

Answer:

Step-by-step explanation:

1 = 1/16 (one chance on 16

2 = 7/16 (the non shaded parts are 7, while the total parts are 16)

3 = 11/16 ( 11 is unshaded + even)

4 = 4/16 = 1/4 (the favourable possibilities are: 13, 14, 15, 16)

Answer:

12 pet

Step-by-step explanation:

6 of Daniel pets are birds, that is chicken and Parrot.

But, Daniel has 2 parrots, therefore the number of chickens = 6 - 2 = 4. He has 4 chickens.

The number of chicken = number of goldfish - 1; number of goldfish = number of chicken + 1, hence number of goldfish = 4 + 1 = 5

Number of goldfish = number of turtles + 4; number of turtles = number of goldfish - 4 = 5 - 4 = 1.

Therefore total number of pets = Parrot + chicken + goldfish + turtles = 2 + 4 + 5 + 1 = 12

Daniel has 12 pets

Answer:

481

Step-by-step explanation:

Lets say width = x

Length = x+24

Perimeter is 100 so

100=x+24+x+24+x+x

100=4x+48

100-48=4x

52=4x

x=13

So width = 13

Length = 37

37x13=481

Answer:

  A-  Triangle 2: {8, 15, 17}

Step-by-step explanation:

You may recognize that the triple of choice A is a Pythagorean triple, so can be the side lengths of a right triangle.

Checking the numbers can be done nicely by a graphing calculator or spreadsheet to help avoid the tedium of doing it "by hand".

The basic idea is that the triangle will be a right triangle if the sum of the squares of the shorter sides is the square of the longer side.

Answer:

f^(-1)(x) = (x-b)/m  or  x/m - b/m

Step-by-step explanation:

f(x) = y = mx + b

To find the inverse function, interchange x and y and solve for y, i.e.

x = my + b

my = x-b

y = (x-b)/m = x/m - b/m

Answer: 25

Answer:

4 yards

Step-by-step explanation:

Given data

Area of square =16 square yards

We know that area of square is

Area =l²

16=l²

l= √16

l=4 yards

Hence the dimension of the sides is 4 yards each

Answer:

A 5040

B 35

Step-by-step explanation:

A  There are 7 ways to put the first picture.  There are 6 pictures left and 6 ways to put the 2nd picture.  There are now 5 pictures left and 5 ways to put the 3rd picture.  And so on

7 * 6*5*4*3*2*1

5040

B  If we can only have 3 pictures and order does not matter

7 choices for the first * 6 *5

But

We have to take into account order

The first picture can go into 3 slots, the second into 2 and the third 1 so divide by 6

(7*6*5)/ (3*2*1)

35

Answer:

D. g(x)=1/4^2

Step-by-step explanation:

the wider the graph is, the smaller the number in front is like: "1/2" or "2/3". The steeper or smaller the parabola is, the bigger the number in front is, "10" or "495"

Answer:

Step-by-step explanation:

True

Option B is correct that is false.

We have been given a figure we need to tell that the two lines are perpendicular

Lines are perpendicular if they meet at the right angle.

Line CD is perpendicular AB to vice-versa is not true.

Hence, Option B is correct

Lines that intersect each other forming a right angle are called perpendicular lines. Example: the steps of a straight ladder; the opposite sides of a rectangle. The symbol is used to denote two perpendicular lines: ⊥ ⊥ .

The perpendicular symbol is ⊥. It is used between the two lines to show that they are perpendicular to each other. Perpendicular lines intersect at right angles (90°) while parallel lines are parallel to each other and never intersect.
