1 answer:

jolli1 [7]3 years ago

7 0

Answer:

6 : 7
9 : 10 1/2
12 : 14

Step-by-step explanation:

Multiply the given values by any number you like. The results will be integers if the number is even.

×2 gives 3×2 : (3 1/2)×2 = 6 : 7

×3 gives 3×3 : (3 1/2)×3 = 9 : 10 1/2

×4 gives 3×4 : (3 1/2)×4 = 12 : 14

Meal=$40 find the total cost

zepelin [54]

Answer:

Step-by-step explanation:

You want to leave a 15% tip on a meal that cost $48.

First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.

Second, you need to find out what 15% of your $48 meal cost is.This is always done by multiplying 0.15 by $48.00, or

0.15 x $48.00=$7.20.

So, the amount of tip you are going to leave is $7.20.

This makes the total cost of your meal (to write on your charge slip or other payment)

$48.00 + $7.20 = $55.20.

i hope this may come to use to your rude a s s

Find the surface area of the cone with a diameter of 12 centimeters and a slant height of

Andrej [43]

Answer:

lateral surface area is 160.14 square cm.

Total surface area is 273.16 square cm

Step-by-step explanation:

Lateral surface area of cone is given by $\pi rl$

where r is radius of cone

and l is slant height of cone.

l = 85 millimetres

we know that 10 millimetres is equal to 1 cm

Thus 85 millimetres is equal to 8.5 cm

Thus slant height(l) in cm is 8.5 $\pi rl\\=>\pi 6*8.5\\=> 3.14*51\\=>160.14$

we will use value of $\pi$ as 3.14

Diameter of cone = 12 cm

we know that radius is equal to half of Diameter

radius of given cone = 1/2 *Diameter = 1/2 * 12 = 6 cm.

Thus lateral surface area of cone is given by

$\pi rl\\=>3.14*6*8.5\\=>153$

Thus, lateral surface area is 160.14 square cm.

Area of base of cone will be area of circular base

area of circle is given by $\pi r^2$

Thus area of base is given below

$\pi r^2\\=>3.14*6^2\\=>113.04$

area of base is 113.04 square cm

Total surface area of cone is sum of area of base and lateral surface area

Total surface area = 160.14+113.04 = 273.16 square cm.

8.96 is what percent of 112

ahrayia [7]

8%, would be your answer.
100= 8.96 / 112 = 12.5
Now,
100=12.5
12.5 12.5
Cancel out, and divide.
12.5 / 12.5 = cancelled , 100 / 12.5 = 8

Is the graph of y=3/2x-4 paralel to the graph of y=-3/2x-4

Sholpan [36]

The slope of the first function is 3/2, and the slope of the second is -3/2.

For two graphs to be parallel, the slope must be the same.

3/2 does not equal -3/2, and therefore the two graphs are not parallel.
