Answer:
1 : 2
Step-by-step explanation:
this is a 30-60-90 triangle which is a special right triangle. the ratio of the sides is x: x*sqrt(3): 2x, in the order short leg: long leg: hypotenuse. so the ratio of the short leg to the hypotenuse is x:2x or 1:2
Well cutting off the small 4x2 you get 8 plus’s the 7x2 is 14 so just add those together you should get 22in ^2
Answer:
x= 8 inches
Step-by-step explanation:
you left out the other lengths but since i had this same question once, the other lengths are 12 and 2-
dimensions of the box:
12 in x 2 in x ?
=272 square inches
and we know that there are 6 faces
area= 2 *(12 * 2) + 2 *(2*x) + 2 *(12*x)
area = 272 sq. in. = 48 + 4x + 24x
272 = 48 + 28x
272 - 48 = 28x
224 = 28x
x = 8 inches
good luck :)
i hope this helps
brainliest would be highly appreciated
have a nice day!
1- Two times the sum of four and eight
2 x (4+8)
2- Seven less than eight
8-7
3-The product of x squared and thirteen
13x²
Answer:
2. 40.83 or 13π
3. a) 6π/5
b)21.6π
Step-by-step explanation:
2. Use the proportion arc length over angle measure:
x/360 = 7.94/70
x = 360 * .113 = 40.83 or 13π in exact form
3. a) 24π/20 because circumference divided by the total number of slices which reduces to 6π/5
b) 360/20 = 18 degrees per slice, so 13 slices have an angle measure 234 degrees
Set up a proportion between the area of the full pizza over the angle measure and the area of the pizza (the unknown value being solved) and its angle measure
144π/360 = x/234
(234*144π)/360 = 21.6π
