Answer: 119.28

Step-by-step explanation:

the formula for surface area of a rectangular prism is 2(width×length+height×length+height×width)

in this case, it would be 2×(2.1×8.4+4×8.4+4×2.1)=119.28

I really need help on this:3 2/4+ 2 3/4+ 2 3/4+ 2 1/4+ 1 1/4+ 1
labwork [276]

Answer:

15

Step-by-step explanation:

3 2/4+ 2 3/4+ 2 3/4+ 2 1/4+ 1 1/4+ 1

first add the whole numbers so 3+2+2+2+1+2=12

then we are left with the fractions. 11/4 divides into 2 with a remainder of three so we add it to the top.

From here we have 2/4+3/4+3/4+1/4+3/4

add them together and we get 12/4=3. Then add back our whole numbes to get 12+3=15

Same height when both equations are equal

-16x^2 +  74x + 9 = -16x^2 + 82x

82x - 74x = 9

8x = 9

x = 9/8

x = 1.125

x = 1.13 ---->rounded to nearest hundredths of seconds

Please help<br> Geometry <br> Will give top answer for someone to answer correctly.
Setler79 [48]

Answer:

Length of the minor arc AB = 5.27777777778 cm

Step-by-step explanation:

Here you would require a simple proportionality.

The ratio of the degree of the minor arc (95 degrees) over the total, 360 degrees of every circle, comparative to the length of the minor over the circumference (20 cm).

Here we can propose that the length of the minor can be equal to x.

Now let's substitute the known values:

95 / 360 = x / 20

Now cross multiply:

360 * x = 95 * 20 ⇒

360x = 1900 ⇒

x = 5.27777777778 ⇒

length of the minor arc AB = 5.27777777778 cm
