The floor inside the horse barn is 45 feet long and 20 feet wide . The barn has 2 floors ( an upstairs and downstairs ) and both floors has the same size . What is the total area for both floors of the barn

Answers

to find area we multiple length by width

20 times 45 is 900

then multiply that by 2 because there are two floors that are that size

900 times 2 is 1800

the total area for both floors is 1800 square feet

One evening, 2/3 of Mrs. Thorne's, students watched a reality television show. Mrs. Lombardo's students, 4/5 watched the same reality show. Which teacher had more students that watched the reality show? Explain

Answers

Mrs.Lombardo.if you do the math out, 4/5 and 2/3 give you an LCD (Least Common Denominator) of 15, so this means 4/5 = 12/15, and 2/3 = 10/15. 4/5 is greater than 2/3. 

16. The temperature on the ground during a plane's takeoff was -7°F. At 38,000 feet in the air, the temperatureoutside the plane was -29°F. Find the difference between these two temperatures.a. 36 FC. -22°Fb. 36°Fd. 22 F

Answers

The difference between given two temperatures will be  -22^0 F .

What is temperature ?

Temperature is the measure of hotness or coldness of something which is expressed in terms of several scales, including Fahrenheit and Celsius.

We have,

Temperature on the ground =-7^0F

Temperature in the air =-29^0F

So, the difference between temperatures =Temperature in the air  - Temperature on the ground

The difference between temperatures = -29-(-7)            

                                                                 =-29+7

                                                                  =-22^0F

Hence, we can say that the difference between given two temperatures will be  -22^0 F .

The answer is -22°F because you are subtracing -7°F from -29°F.

Which of the following shows the Commutative Property of Addition? (4 + 3) + x = (3 + 4) + x ab = ba r + (s + t) = (r + s) + t n + 0 = n

Answers

commutative says you can add or multiply in any order

basically goes like this
a+b=b+a or
ab=ba

so what we need is something where the order change, nothing else
first one: (4+3)+x=(3+4)+x, the order changed, correct

2nd
ab=ba, this is not addition

3rd
r+(s+t)=(r+s)+t this is associative property

4th
n+0=n
this is zero addition property

a and b are vectors such that |a| = √3, |b| = 1, and the angle between them is 5π/6. Using scalar product, find the exact value of |2a + b|.

Answers

Answer:

|2a + b| = 2√(3) + 1

Step-by-step explanation:

|a| = √(3)

|b| = 1

θ = 5π/6

For scalar vectors, A.B = |a|.|b|.cosθ

a

|2a| = 2*√(3) = 2√(3)

|2a + b| = 2√(3) + 1

Since we don't have to find the scalar or dot product, there's no need to use the formula requiring the angle between them

|2a + b| = 2√(3) + 1
