The picture below shows Annie and her younger brother Tommy’s money.
lawyer [7]

Step-by-step explanation:

Annie: 4 dollars = $4 11 dimes = 11 x 0.10 = $1.1 ( since 1 dime = 0.10 dollars)

4 pennies =4 x 0.01= $0.04 ( since 1 penny = 0.01 dollars)

Tommy 3 dimes = 3 x 0.10 = $0.3 3 pennies = 3x 0.01 = $0.03

Adding the values: 4 +1.1+0.04+0.3+0.03 = $5.47

Hiking up a mountain, you notice that the air temperature drops 10 degrees every 1000 meters increase in elevation. Write a mult
Elina [12.6K]

 decrease in temperature if you hike up the mountain 3000 meters is  -30° .

<u>Step-by-step explanation:</u>

Here we have , Hiking up a mountain, you notice that the air temperature drops 10 degrees every 1000 meters increase in elevation . We need to find Write a multiplication expression to represent the decrease in temperature if you hike up the mountain 3000 meters. Let's find out:

For every 1000 meters rise in elevation , there is decrease in 10° of temperature . So , For rise in n meters in  elevation , there is decrease in n×10° of temperature i.e

Decrease in temperature = (n/1000)×(-10) i.e.

⇒  (n/1000)×(-10)

⇒ \frac{n}{1000}(-10)

At n = 3000 meters:

⇒ \frac{3000}{1000}(-10)

⇒ 3}(-10)

⇒ -30°  

Therefore ,  decrease in temperature if you hike up the mountain 3000 meters is  -30° .

Line a is purpendicular to line b. if the slope of line a is 7 than what is the slope of line b
MA_775_DIABLO [31]

The slope of the perpendicular line b is -1/7 if the slope of the perpendicular line a is 7.

According to the question,

Line 'a' is perpendicular to the line 'b'. If the slope of the line 'a' is 7.

The condition of slopes if two lines are perpendicular m₁ m₂ = -1

(7)(m₂) = -1

   m₂ = -1/7

Hence, the slope of the perpendicular line b is -1/7 if the slope of the perpendicular line a is 7.
