A circular gift has a 4.75 inch radius. alyssa wants to wrap a ribbon that costs $0.50 per inch around the gift. How much money

Montano1993 [528]

The Alyssa will spend $14.915 for wrap a ribbon around the gift, if a ribbon costs $0.50 per inch.

Step-by-step explanation:

The given is,

A circular gift has a 4.75 inch radius

Ribbon that costs $0.50 per inch

Step:1

Formula to calculate the perimeter of circle,

$Perimeter, P = 2\pi r$ ......................(1)

Where, r - Radius of circle

From the given,

r = 4.75 inches

Equation (1) becomes,

$P = 2 (\pi )(4.75)$

$= 2(3.14)(4.75)$ (∵ $\pi$ = 3.14)

$=2(14.915)$

$=29.83$

Perimeter, P = 29.83 inches

Step:2

Cost for wrap the ribbon to around the circular gift,

= Perimeter of circular gift × ribbon cost per inch

= (29.83 × 0.50)

= $14.915

Cost for wrap the ribbon to around the circular gift = $14.915

Result:

The Alyssa will spend $14.915 for wrap a ribbon around the gift, if a ribbon costs $0.50 per inch.

the mean of marks scored by 100 students was found to be 40. Later on, it was discovered that a score of 53 was misread as 83. F

liberstina [14]

As the sum of marks of others remain unchanged , let their sum be x . As the mean using 83 was 40 , we have ,

(x +83)/100 = 40

x + 83 = 4000

x = 3917

Now mean using 53 ,

(x +53)/100

(3917+53)/100

39.7.

Hope it helps , plz mark as brainiest :-)

Please help with this algebra!! I’m

stiks02 [169]

Answer:

(-4, -1)

Step-by-step explanation:

x = 4y

-4x - y = 17

Plug in 4y for x in the second equation:

-4(4y) - y = 17

Simplify. Remember to follow PEMDAS. Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other.

First, multiply 4y with -4:

-4(4y) = -16y

-16y - y = 17

Simplify. Combine like terms:

-16y - y = 17

-17y = 17

Isolate the variable, y. Divide -17 from both sides:

(-17y)/-17 = (17)/-17

y = 17/-17

y = -1

Plug in -1 for y in the first equation:

x = 4y

x = 4(-1)

x = -4

x = -4, y = -1

Answer: (-4, -1)

The admission fee at a zoo is $2 for children and $4 for adults. If 1800 people enter the zoo and $6000 is collected, how many a

ipn [44]

Answer:

The number of adults is $1,200$

Step-by-step explanation:

Let

x------> the number of children

y------> the number of adults

we know that

$x+y=1800$ -------> equation A

$2x+4y=6000$ -------> equation B

Multiply equation A by $-2$

$-2(x+y)=-2*1800$ --------> $-2x-2y=-3600$ ------> equation C

Adds equation B and equation C

$2x+4y=6000\\-2x-2y=-3600\\---------\\4y-2y=6000-3600\\2y=2400\\y=2400/2\\y=1200$
