5.7*10^9-300,000,000= 5,400,000,000
5,400,000,000=5.4*10^9
So the cell phone users worldwide is 5.4*10^9 more than the cell phone users in USA.

Answer: x = the quantity of 5 plus or minus the square root of 29 all over 2

Step-by-step explanation:

The given quadratic equation is expressed as

x² - 5x - 1 = 0

The equation is already in the standard form of ax² + bx + c

The general formula for solving quadratic equations is expressed as

x = [- b ± √(b² - 4ac)]/2a

From the given quadratic equation,

a = 1

b = - 5

c = - 1

Therefore,

x = [- - 5 ± √(- 5² - 4 × 1 × - 1)]/2 × 1

x = [5 ± √(25- - 4)]/2

x = [5 ± √29]/ 2

x = ( 5 + √29)/- 2 or x = (5 - √29)/2

I need help on this question ​
sasho [114]

Answer:

The shape is a kite and x=26

Step-by-step explanation:

The shape is a kite because the two adjacent sides at the right match and the two sides on the left match

To find x:

125+125=250

360-250=110

(3x-11)+(2x-9)=110

Combine like terms: 5x-20=110

Add 20 to both sides: 5x-20+20=110+20

5x=130

Divide both sides by 5: 5x/5=130/5

x=26

Can someone help me with this Geometry problem, please?
Doss [256]

Hello from MrBillDoesMath!

Answer:

72


Discussion:

Total Surface area = area of pyramid base + 4 ( area of triangular face)

In our case this becomes

                                 4*4                               + 4(  (1/2) (4)(7) )  =

                                 = 16 + (2)(4)(7)

                                 = 16 + 56        

                                 = 72

which is the first choice.  

Note: the area of a triangular face was computed using (1/2) b h, which in our case is

(1/2) (4) (7)


Thank you,

MrB

A group of 62 students were surveyed, and it
Bingel [31]

Answer:

29 students liked apples, but not bananas and guavas at the same time. (11 students liked apples and liked neither bananas nor guavas.)

9 students liked bananas only.

26 students liked apples or bananas but not guavas.

59 students liked bananas or guavas or apples, (That is the number of students that liked one or more of the three fruits.)

12 students liked apples and guavas but not bananas.

Step-by-step explanation:

Start by drawing a Venn Diagram. (Refer to the first attachment.)

  • The outermost rectangle denotes the set of all 62 students that were surveyed.
  • The top-left circle denotes the set of surveyed students that liked apples.
  • The top-right circle denotes the set of surveyed students that liked bananas.
  • The other circle denotes the set of surveyed students that liked guavas.

Using information from the question, fill in the number of students in each section.

Start with intersection of all three circles denotes the set of surveyed students that liked all three fruits.

The question states that there are 5 students in this set. Besides, this set isn't a superset of any other set. Therefore, write the number 5\! in the corresponding place without doing any calculation.

Continue with the intersection of students that liked two fruits only. For example, the question states that 11 surveyed students liked apple and bananas. However, that 11\! students also include the 5 surveyed students that liked all three fruits (apple, banana, and guava.) Therefore, only 11 - 5 = 6 surveyed students liked apple and banana only (but not guava.)

Similarly:

  • 15 - 5 = 10 surveyed students liked bananas and guavas only.
  • 17 - 5 = 12 surveyed students liked apples and guavas only.

The question states that 33 surveyed students liked guavas. However, among that 33\! students:

  • 10 of them also liked banana but not apples (bananas and guavas only.)
  • 12 of them also liked apples but not bananas (apples and guavas only.)
  • 5 of them also liked apples and bananas (all three fruits.)

Therefore, only 33 - 10 - 12- 5 =6 surveyed students liked guava but neither apple nor banana (guava only.)

Similarly:

  • 34 - 6 - 5 - 12 = 11 of the surveyed students liked apples but neither guava nor banana (apple only.)
  • 30 - 6 - 5 - 10 = 9 of the surveyed students liked bananas but neither apple nor guava (bananas only.)

Among the 62 surveyed students, 62 - (11 + 6 + 9 + 12 + 5 + 10 + 6) = 3 of them liked none of the three fruits.

Refer to the second diagram attached for the Venn Diagram with the corresponding numbers.

Students that liked apples but not bananas and guavas at the same time include:

  • Students that liked apples only.
  • Students that liked apples and bananas, but not guavas (apple and banana only.)
  • Students that liked apple and guavas, but not bananas (apple and guava only.)

These three subsets include 11 + 6 + 12 = 29 surveyed students.

It was previously found that 9 students liked bananas only.

Students that liked apples or bananas but not guavas include:

  • Students that liked apples only.
  • Students that liked bananas only.
  • Students that liked apples and bananas, but not guavas (apple and banana only.)

That include 11 + 6 + 9 = 26 surveyed students.

Among these surveyed students, 11 + 6 + 9 + 12 + 5 + 10 + 6 = 59 of them liked at least one of the three fruits.

It was previously found that among these surveyed students, 12 of them liked apples and guavas only. That gives the number of students that liked apples and guavas, but not bananas.
