Answer:

Perimeter = 46.6 m

Area = 78.36 m²

Step-by-step explanation:

Perimeter is just the outsides, so add 3.7 + 12.3 + 4.5 +11 AND the sides you aren't given. To find them, you do 11-3.7 = 7.3 and 12.3-4.5 = 7.8. So you add 3.7 + 12.3 + 4.5 + 11 + 7.3 + 7.8 = 46.6

Area is the inside, so you multiply length by width. You can split it different ways, but I multiplied by 3.7*12.3 first, giving 45.51. Now to find the area of the other box, you need to subtract 11 by 3.7, which we saw was 7.3. Now we can multiply 7.3 by 4.5, which is 32.85. Then you add 45.51 and 32.85 to get 78.36.

Pls help me, cause I don't understand one bit of it at all​

Answer:

I promise you this is easier than it looks, just bare with me.

You have to order these numbers from the smallest to the biggest. Now before we do this, we wanna make the fractions and mixed numbers decimals to make this easier.

5 8/11

Convert the fraction to a decimal: Divide the numerator by the denominator.  (8 divide by 11).

Add this decimal number to the whole number part of the mixed number. (0.72 plus 5)

It would be 5.72

Now 57/10

The same steps as the last one, but since it isn't a mixed number you don't add anything. (57 divided by 10)

It would be 5.7

Now we have to order them from least to greatest. How do we figure that out? Well lets list the numbers that we have now:

5.72

5.7

5.67

5.726

Now since they all have the same whole number, we just have to look at the numbers after the decimal.  Well the least number we have here is "7". Then it would be 67, then 72, then 726.

So the answer would be from least to greatest:

5.7

5.67

5.72

5.726

I hope this helps..sorry if I took so long I wanted to make sure I explained this as good as I can so you don't keep struggling. Good luck, take care <3

Have a good night/day (:! Much love!

Solve the equation 4 sin (x +30°) = 2<br>for 0 &lt; x &lt; 365​
tatuchka [14]

>

4 \sin(x + 30)  = 2 \\  \sin(x + 30 ) =  \frac{2}{4}   \\  \sin(x + 30)  =  \frac{1}{2}  \\  \sin(x + 30)  =  \sin(30)  \\ x + 30 = 30 \\ x = 30 - 30 \\ x = 0

Hence, x = 0°, 180° and 360° <em><u>Ans</u></em>
