Answer: Circumference of Earth= 25120 miles

Step-by-step explanation:

Given: The circumference of a circle can be found using the formula [tex]C = \pi d[/tex], where d= diameter of the circle.

Earth's diameter = 8000 miles (approx)

The circumference of circle = [tex]3.14\times 8000[/tex]  [substitute values in formula]

The circumference of circle = 25120 miles (approx)

Hence,  the circumference of Earth= 25120 miles (approx)

GIVEN: Here given that f(x)=g(x)

TO FIND: We need to find by the given relation what f(x) and g(x) represents.

SOLUTION:

f(x) is a function of x.

Also, g(x) is function of x.

The are holding the relation of equality that means

graphically we get a curve or a conic section by it.

Algebraically it gives the values of x.

Answer:

145 + 33n

Step-by-step explanation:

Let

n = number of members in the club

Day 1:

Cost = 50 + 18n

Day 2:

Cost = 95 + 15n

Total cost two-day field trip = day 1 + day 2

= (50 + 18n) + (95 + 15n)

= 50 + 18n + 95 + 15n

= 145 + 33n

Total cost two-day field trip = 145 + 33n

An expression that represents the total cost in dollars for two days for the n members of the club is given by 145 + 33n

Answer:

w² + 5w = 36

Step-by-step explanation:

Since the pen is a rectangle, its area, A = lw where l = length and w = width.

Since the length of the fence is 5 feet longer than its width, we have l = w + 5

So, A = lw = (w + 5)w = w² + 5w

Since A = 36 ft², we have that

36 = w² + 5w

w² + 5w = 36

Which is the required equation.

Answer:

A

Answer:

Perimeter = 12+4pi

Area = 16+8pi

Step-by-step explanation:

Description of the assumed shape:

A rectangle 2 x 8 superimposed on a semi-circle of radius 4.

Perimeter:

P = 2+8+2+(4)(pi) = 12+4pi

Area :

A = 2*8 +(pi)4^2/2 = 16 + 8pi

Answer:

E is the answer

The question is incorrect. Please see the correct question

Jill, an employee at Old Navy, budgets 1/3 of her yearly salary for clothing. Jill's total clothing bill for the year is $8,220. What is her yearly salary

Answer:

24,660

Step-by-step explanation:

Let y represent her yearly salary

1/3 × y

1/3y

1/3y= 8220

Cross multiply

y= 8220 ×3

= 24,660

Hence Jill yearly salary is 24,660

The answer is 12>x>-7

Step-by-step explanation:

it's first divided into 2 parts

1 . 15 > 2x - 9

2. 2x - 9 > -23

Then solve them individually.

let's do it,

First half

15 > 2x - 9

15+9 > 2x

24 > 2x

24/2 > x

12>x

Second half

2x-9>-23

2x>-23+9

2x>-14

x>-14/2

x>-7

Joining of the two halves

We have :

12>x>-7

Answer:

3x - 6

Step-by-step explanation:

Using the keywords "a number" and "few than" and "times" we can identify the expression.

Answer:

Let the number be x

Basically, 3 times a number is 3x and 6 fewer than 3 times a number is 3x-6 (that is, 6 is less than 3x)

Hence the required expression is 3x-6.

Answer:

15 = t

Step-by-step explanation:

3 = t - 12

3 + 12 = t

15 = t

Answer:

C:15 if were going off t

Step-by-step explanation:

if you switch around the equation a bit you get t-12=3 now what number minus 12 equals three thats what your trying to find so the only logical answer is C because 15-12=3 so t=15

30 in 2

Step-by-step explanation:

What is the area of the figure below?

Answer:

44

Step-by-step explanation:

Angles that form a straight line add up to equal 180 degrees

Hence, e + 8 + 3e - 4 = 180

                      ^ ( note that we just created an equation that we can use to

                          solve for e )

Using the equation created, we then solve for e

e + 8 + 3e - 4 = 180

step 1 combine like terms

3e + e = 4e

8 - 4 = 4

we now have 180 = 4e + 4

step 2 subtract 4 from each side

180 - 4 = 176

4 - 4 cancels out

we now have 176 = 4e

step 3 divide each side by 4

176 / 4 = 44

4e / 4 = e

we're left with e = 44

Answer: 67 + x = 180

Step-by-step explanation:

Since the angles are supplementary, together they'd add up to 180. Since we do not know the degrees of Angle 2, we arrange x in the equation.

Hope this helps you! Good luck! <3

Answer:

4)56yards²

5)336 yards²

6)375yards²

Step-by-step explanation:

from the graph we acquire that

remember that,

[tex] \displaystyle A _{ \text{rect}} = l \times w[/tex]

thus substitute:

[tex] \displaystyle A _{ \text{rect}} = 4 \times 3.5 \: [/tex]

simplify multiplication:

[tex] \displaystyle A _{ \text{rect}} = 14\: [/tex]

14 means that the rectangle has 14 squares

so,

[tex] \displaystyle 1 \: \text{square} \implies 4 \: { \text{yards}}^{2} \\ 14 \: \text{square} \implies 14 \times 4 \: { \text{yards}}^{2} \\ \qquad = 56 \: { \text{yards}}^{2} [/tex]

likewise

from the graph we acquire that

likewise

[tex] \displaystyle A _{ \text{rect}} = 6 \times 3.5 \: [/tex]

simplify multiplication:

[tex] \displaystyle A _{ \text{rect}} = 21[/tex]

so,

[tex] \displaystyle 1 \: \text{square} \implies 16 \: { \text{yards}}^{2} \\ 21 \: \text{square} \implies 16 \times 21 \: { \text{yards}}^{2} \\ \qquad = 336\: { \text{yards}}^{2} [/tex]

likewise

[tex] \displaystyle A _{ \text{rect}} = 6 \times 2.5 \: [/tex]

simplify multiplication:

[tex] \displaystyle A _{ \text{rect}} = 15[/tex]

so,

[tex] \displaystyle 1 \: \text{square} \implies 25 \: { \text{yards}}^{2} \\ 15 \: \text{square} \implies 15 \times 25 \: { \text{yards}}^{2} \\ \qquad = 375\: { \text{yards}}^{2} [/tex]

Answer:

Step-by-step explanation:

-4(1)^2 + 15(1)^2 =5

-4 + 15 = 5

since the equation is false,   15-4  does not equal 5  , then something has been left off the equation.      look carefully , did you forget anything?
