Between the time Iko woke up and lunchtime,the temperature rose by 11.Then by the time he went to bed,the temperature dropped by

dimaraw [331]

Answer:

11 + ( - 14)

Explanation:

The complete question is:

Between the time iko woke up and lunchtime, the temperature rose by 11º. Then by the time he went to bed, the temperature dropped by 14º.

Write an addition expression for the temperature relative to when iko woke up.

<h2>Solution</h2>

It is said that between the time Iko woke up and lunchtime, the temperature rose by 11 degrees. A rise means the temperature increased and you must add 11º.

Then, relative to when Iko woke up the temperature is:

+ 11º

Then, by the time Iko went to bed, the temperature dropped by 14º. A drop means that the change is negative. This means that you must add a negative number, and the additive expression is:

+ 11º + (- 14º).

If you want the overall change in temperature you do the operation:

11 + (-14) = 11 - 14 = - 3. A net decrease of 3º.

But the answer to this question is the additive expression:

11 + ( - 14) ← answer

A rectangle has a length of 6.5m and a width of 7.3m what is the area and the perimeter

Bad White [126]

Step-by-step explanation:

<h3>Given:</h3>

Length of the rectangle = 6.5 m

Width of the rectangule = 7.3 m

First case,

Area of the rectangle

= length × width

= 6.5 m × 7.3 m

= 47.45 sq.m (Ans)(i)

Second case,

Perimeter of the rectangle

= 2(length + width)

= 2(6.5 + 7.3)m

= 2 × 13.8 m

= 27.6 m (Ans)(ii)
