Answer:

Area=7.071428571

Step-by-step explanation:

Before finding its area lets find its radius.

Given,

Diameter=3

Now,

Radius,r=D/2

          r =3/2

           r=1.5            

Again,

         Area of circle,A= pi*r*r

                           A =22/7*1.5*1.5

                           A=22/7*2.25

                           A=49.5/7

                           A=7.071428571 ans.

Step-by-step explanation:

The number of purple T shirts that the Trenton's scouting group made is 15.

A pie chart is a type of graph where a circle is divided into certain sectors where each sector shows a proportion of the whole.

Given is a pie chart or circle graph.

This shows the number of different colored T shirts that the Trenton's scouting group made.

Total number of T shirts = 100

Total degree of a circle = 360°

The circle is divided in to various sections with each section of different degree.

Angle measure for the purple section = 54°

Proportion of purple T shirts to the full T shirts = 54 / 360

                                                                             = 0.15

Number of purple T shirts in total of 100 T shirts = 0.15 × 100

                                                                                = 15

Hence the number of purple T shirts made is 15.

Given the distance Maria ran each day, the total distance she ran during a fifteen ( 15 ) days strech is 55.5miles.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, we have,

Expression for the Total of Distance ran by Maria

Total distance = Distance ran each day × Number days

Given the data in the question;

Distance ran each day by Maria Dm = 3.7miles

Number days ran n = 15days

Total number of distance ran by Maria TDm = ?

Total distance = Distance ran each day × Number days

TDm = Dm × n

We substitute in our values

TDm = 3.7miles × 15

TDm = 55.5miles

Given the distance Maria ran each day, the total distance she ran during a fifteen ( 15 ) days strech is 55.5miles.

So 3 1/2 pounds as whole pounds and ounces would be:

3 pounds and 8 ounces

and/or

3 lbs. and 8 oz.

Answer:

All of them

Step-by-step explanation:

all of them add to 60

24 pencils and 36 stickers= 60 items

3 bags with 8 pencils and 12 stickers 3(8+12) =60

6 bags with 4 pencils and 6 stickers 6(4+6) =60

3 bags with 10 pencils and 10 stickers 3(10+10)=60

5 bags with 6 pencils and 6 stickers 5(6+6)=60

12 bags with 2 pencils and 3 stickers  12(2+3)=60

4 bags with 6 pencils and 9 stickers 4 (6+9) =60

Given a number N    . The task is to find all such numbers less than N and are a product of exactly two distinct prime numbers.

For Example, 33 is the product of two distinct primes i.e 11 * 3, whereas numbers like 60 which has three distinct prime factors i.e 2 * 2 * 3 * 5.

Step-by-step explanation:

Since there is 10 lines separating -3 and -4, that means the space between 2 lines in 1 tenth, and b is 3.5 lines away from -3. Making it -3.35

have a nice day :)

Answer:

B

Step-by-step explanation:

Each section represents 0.1

You would count 3 sections to the left of -3 because -3.35 is less than -3. You would end up at -3.3. Move to the left half a section for 0.05 and you would end up at point B, which is equal to -3.35.

When doing problems like this, remember the PE part of PEMDAS.

Parentheses

Exponents

You have to do parentheses first. Then exponents.

[tex](-4 + -3) = -7[/tex]

Next, find the value of 2 squared, then multiply the previous sum by 2 squared, also the term for the number times itself.

[tex]2^2[/tex] [tex]= 4[/tex]

[tex]-7 * 4 = -28[/tex]

Now, subtract by -1

[tex]-28 - 1 = -29[/tex]

Answer:

The y intercept is -8, or (0, -8)

Step-by-step explanation:

p(x)=-3(x-2)²+4

p(x)=-3(x²-4x+4)+4

p(x)=-3x²+12x-12+4

p(x)=-3x²+12x-8

This is quadratic

In p(x)=ax²+bx+c

c is the y intercept

Therefore the y intercept is -8, or (0, -8)

Hope this helps! :D

Answer:

(0,-8)

Step-by-step explanation:

The y intercept occurs when x = 0 , so put in x = 0

-3(0-2)^2 + 4   = -8  

so y-axis intercept is   ( 0, -8 )

The cost of one box of paper clips is $1.85 and the cost of one package of index cards is $3.95

Step-by-step explanation:

Eldora and Finn went to an office supply store together

Eldora bought 15 boxes of paper clips and 7  packages of index cards for a total cost of $55.40

Finn bought 12 boxes of paper clips and 10 packages of  index cards for a total cost of $61.70

We need to find the cost of one box of paper clips and the cost of one package of  index cards

Assume that the cost of one box of paper clips is $x and the cost of one package of  index cards is $y

∵ x represents the cost of one box of paper clips

∵ y represents the cost of one package of  index cards

∵ Eldora bought 15 boxes of paper clips and 7  packages of

  index cards for a total cost of $55.40

∴ 15x + 7y = 55.4 ⇒ (1)

∵ Finn bought 12 boxes of paper clips and 10 packages of  

  index cards for a total cost of $61.70

∴ 12x + 10y = 61.7 ⇒ (2)

Now we have system of equations to solve it

Multiply equation (1) by -10 and equation (2) by 7 to eliminate y

∵ -10(15x) + -10(7y) = -10(55.4)

∴ -150x - 70y = -554 ⇒ (3)

∵ 7(12x) + 7(10y) = 7(61.7)

∴ 84x + 70y = 431.9 ⇒ (4)

Add equations (3) and (4)

∵ (-150x + 84x) + (-70y + 70y) = (-554 + 431.9)

∴ -66x = -122.1

- Divide both sides by -66

∴ x = 1.85

Substitute the value of x in equation (1) or (2) to find y

∵ 12(1.85) + 10y = 61.7

∴ 22.2 + 10y = 61.7

- Subtract 22.2 from both sides

∴ 10y = 39.5

- Divide both sides by 10

∴ y = 3.95

The cost of one box of paper clips is $1.85 and the cost of one package of index cards is $3.95

Answer:

1/2 and -1/2

Step-by-step explanation:

The square root of a fraction is equal to the square root of the numerator divided by the square root of the denominator. In this case, it is √1 / √4. The square root of 1 is still 1, so 1 is the numerator. The square root of 4 is 2, so 2 is the denominator. The fraction is 1 / 2. However, if you square -1/2, you also get 1/4, just like when you square 1/2. Therefore, the second choice is the right option because it has the correct, and number of, answers.
