4.

What number should be added ti -4/11 to get -3/8

Answer»

ANSWER:

-1/88 should be added

Step-by-step explanation:

-4/11 + X = -3/8

x= -3/8+4/11

x= -33+32 /88 (LCM is 88)

x= -1/88

Let's verify

-4/11+ (-1/88) = -3/8

-4/11 - 1/88 = -3/8

-32-1/88 = -3/8

-33/88 = -3/8

Bring it to lowest form

-3/8 = -3/8

The mode of five numbers is 1 and the mean is 4 and the median is 5. Find the numbers

Answer»

GIVEN : The mode of five numbers is 1 and the mean is 4 and the MEDIAN is 5.

To Find : the numbers

Solution:

mode of five numbers is 1

Hence atleast two 1 will be there

median is 5

Hence 1 1 5 are three number

1 1 5 X y

Mean = 4

=> 1 + 1 + 5 + x + y = 4 * 5

=> x + y = 13

5 + 8 = 13 ( 5 is not possible as then mode will be 2)

6 + 7 = 13

Hence 5 numbers are

1 1 5 6 7

Mode = 1

Median = 5

Mean = 4

42.	which barrel shown in the blow figure can hold more water one bareel height 4cm and diameter 3cm and another bareel height is 3cm diameter 4cm
Answer» ANSWER: barrel 2 Step-by-step explanation: barrel is in shape of cylinder consider "#" to be "PI" volume of cylinder = #r²h volume of barrel 1 = #r²h = ( 22 / 7 ) X ( 1.5 ) ² x 4 [ radius = diameter / 2 = 3 / 2 = 1.5 CM ] = 3.14 x 2.25 x 4 = 28.26 cm³ ( approx to 2 decimals ) volume of barrel 2 = #r²h = ( 22 / 7 ) x 2² x 3 [radius = diameter / 2 = 4 / 2 = 2 cm] = 3.14 x 4 x 3 = 37.68 cm³ ( approx to 2 decimals ) barrel 2 has more volume than barrel 1 so it can hold more water.

42.

which barrel shown in the blow figure can hold more water one bareel height 4cm and diameter 3cm and another bareel height is 3cm diameter 4cm

Answer»

ANSWER:

barrel 2

Step-by-step explanation:

barrel is in shape of cylinder

consider "#" to be "PI"

volume of cylinder = #r²h

volume of barrel 1 = #r²h

= ( 22 / 7 ) X ( 1.5 ) ² x 4 [ radius = diameter / 2 = 3 / 2 = 1.5 CM ]

= 3.14 x 2.25 x 4

= 28.26 cm³ ( approx to 2 decimals )

volume of barrel 2 = #r²h

= ( 22 / 7 ) x 2² x 3 [radius = diameter / 2 = 4 / 2 = 2 cm]

= 3.14 x 4 x 3

= 37.68 cm³ ( approx to 2 decimals )

barrel 2 has more volume than barrel 1 so it can hold more water.

Answer» The road will be divided into four roads of 5km and 2 km long interconnected road. Explanation: According to my knowledge, four cities should be NEIGHBORING cities if they had to be joined by a SINGLE road of 22 km. So they MUST be 5km APART from each other ar four different ends. If we ASSUME that the cities are equally apart by 5km. Then these cities will have a road of 5km each and there will be an interconnected road of 2 km long that will connect all the four roads of 5km long.
