Seven times a number minus the number is -48. Find the number.

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.

Answer:

180-132 = 48

C. 48 degrees

Answer:

Obtuse

I believe it will be obtuse because the side lengths would take up the shape of something like this, depending on how you put it:

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:

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

Answer:

the answer is :C midsegment

Step-by-step explanation:

because the LINE SEGMENT is in the MIDDLE of the triangle

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:

[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:

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:

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:

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.

Answer:

The answer is 57

Step-by-step explanation:

25 X 3 = 75

75 - 18 = 57

Good luck :)

Answer:

First multiply 25 by 3 which gives you 75.

You then take 75 minus the amount of pink lemonade she has already sold, which is 18.

Your answer should be 57.

So Sofie has 57 cups of pink lemonade left for sale.

Answer:

k=1.1

Step-by-step explanation:

-1.1k=-1.21

divide by -1.1 on both sides to cancel out the -1.1 in front of k so you just have k

Answer:

k = 1.1

Step-by-step explanation:

-1.1k= -1.21

Divide each side by -1.1

-1.1k/-1.1 = -1.21/-1.1

k = 1.1

  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:

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: 25

Step-by-step explanation:

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

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:

4 yards

Step-by-step explanation:
