Answer:

Yep, 53°

Step-by-step explanation:

Sum of angles in a triangle equals 180.

We have two angles: 90° (since it is a right angle triangle) and 37°

Therefore 180 - (90+37) = 180 - 127

Answer is 53°

The expression which converts the height of the bookcase to feet is 1.93 × (3.2808ft / 1m)

To make the conversion of meters to feets , we use dimensional analysis ;

We need to multiply the given measurement in meters by its appropriate or equivalent value in feets :

Recall :

1 meter = 3.2808 feets

Then the height of the bookcase in feets will be :

1.93 meters × 3.2808ft / 1m

Hence, the appropriate expression is : 1.93 meters × 3.2808ft / 1m

To solve this, we have to divide the 18 pounds, in 1/8 portions. We do this with division. To make this problem easier to solve, we need to turn it into a multiplication problem (opposite of division). To still make the problem correct, we have to take the opposite of one of our numbers. Let's take 1/8, and turn it into 8, now we have the problem:

18×8=

Now all we have to do is multiply:

18×8=

Hi! I'm happy to help!

To solve this, we have to start inside the most parenthesis, then work our way out, then divide by 3.

We first have 3^1. There is a rule that x^1=x, so 3^1=3.

((3^1)x3)/3

(3x3)/3

Next, we have 3×3, which is 9..

9/3

Finally, we have 9/3, or 9÷3, which is 3.

3

So, our final answer is 3.

x+y=1984.5

Answer:

No, they are not.

Remember, a ratio can be written as a fraction. So 1:3 is the same as 1/3 and 4:5 is the same as 4/5.

1/3 = 0.33

4/5 = 0.8

As you can see the both don't equal the same numbers, so they aren't equivalent.

Answer: 47.25

Step-by-step explanation:

the equation for finding the area of a triangle is base times height divided by 2

10.5(9)= 94.5

94.5/2=47.25

Answer:

47.25 sq ft is the area. no idea what you want me to do with the 4% though

Step-by-step explanation:

area for traingles = (base×hight)÷2

so your equation would he (10.5ft×9ft)÷2

10.5×9= 94.5

94.5÷2÷47.25

so the answer is 47.25 ft^2 (or simply sq ft)
