Amount of weight gain in first year = 11 pounds

A year can be divided into three parts consisting of four months each.

According to the question;

The baby gained 4 1/4 pounds during the first four months and 3 1/2pounds in its second four months.

Let weight gained in third 4 month be 'x' pounds.

So;

=> Weight gained in first year = Weight gained in first 4 months + Weight gained in second 4 months + Weight gained in third 4 months

=> 11 pounds = 4.25 pounds + 3.5 pounds + x pounds.

=> x pounds = 11 pounds - 7.75 pounds

=> x pounds = 3.25 pounds

Therefore, the baby gain 3.25 pounds in the last four months.

The baby gains 3.25lbs in the last 4 months. 

This problem can be solved by simple subtraction. Take the total amount and subtract the 4 month increments in order to find the find 4 months. 

Total = 1st 4 months + 2nd 4 months + 3rd 4 months

11 = 4.25 + 3.5 + 3rd 4 months

11 = 7.75 + 3rd 4 months

3.25 = 3rd 4 months

Answer:

8 / 15

Step-by-step explanation:

By Pythagoras theorem,

OP² + PQ² = OQ²

OP² + 8² = 17²

OP² = 17² - 8²

       = 289- 64

OP² = 225

OP² = 15²

OP = 15

Formula : -

Tan θ = Opposite side / Adjacent side

Here,

θ = Q

Opposite side = PQ = 8

Adjacent side = OP = 15

Tan Q = 8 / 15

How did you compute sums of dollar amounts that were not whole numbers?
soldier1979 [14.2K]

Answer:

$7.34

Step-by-step explanation:

To compute sum of dollars that are not whole numbers. Using the sum of$5.89 and$1.45 as an illustration :

$5.89 + $1.45

Taking the whole numbers first:

$5 + $1 = $6

Take the sum of the decimals :

$0.89 + $0.45 = $1.34

Sum initial whole + whole of sum of decimal

$6 + $1 = $7

Determine if y varies directly with x. Give the constant of variation, when appropriate. (picture below)
maxonik [38]

Based on the given variation, y does not vary directly with x and the constant of variation are 8, 3.2 and 1.25 respectively.

<h3>Variation</h3>

y = k × x

where,

k = constant of proportionality

y = -40

x = -5

y = k × x

-40 = k × -5

-40 = -5k

k = -40/-5

k = 8

when,

y = 8 and x = 2.5

y = k × x

8 = k × 2.5

8 = 2.5k

k = 8/2.5

k = 3.2

when,

y = 5 and x = 4

y = k × x

5 = k × 4

5 = 4k

k = 5/4

k = 1.25
