Answer:

(-4.5) - (0.5) = -5

Step-by-step explanation:

When are finding things and they give it to you I prefer to use parenthesis sometimes it actually might mean to multiply but since they already give you the what property they want you to do (subtraction) insert the numbers into their appropriate spaces.

a trapezoid has base lengths of 6 and 15 centimeters with an area of 136.5 square centimeters. What is the height of the trapezo

MrRa [10]

•*Ok first let me show you the formula for the Area of the trapezoid.
A=a+b/2 h.(I will be using the letter x for the multiplication sign)

*And here is the formula to find the height of a trapezoid
h=2 x A/a+b (2 times the Area over base "a" plus base "b")

*We need to plug in the numbers: h = 2 x 136.5/6+15
*Next, we add the two bases to get 21: 6+15=21 (h=2 x 136.5)
*Then, divide the total of the two bases (21) from the area to get 6.5: 136.5/21-6.5
*Finally we multiply 2 by 6.5: 2 x 6.5= 13
The height if this trapezoid is 13.

Hope this helps you ☺

Answer:

Lol mcm soalan kamu salah. Pilih A je

Step-by-step explanation:

v = 42
u = -8
a = -5

Masukkan nilai tersebut dalam persamaan v = u + at,

42 = -8 + (-5)t

50 = -5t

t = -10

Popcorn kernels pop independently (i.e. unimolecularly). For one brand at constant temperature, 12 kernels pop in 5 seconds when

likoan [24]

Answer:

no of kernels pop = 4.34

Step-by-step explanation:

given data

kernels pop in 5 second = 12

kernels are present = 235

solution

we get here kernels are pop at rate of here

kernels are pop at rate = 12 ÷ 235

kernels are pop at rate = 0.051063

and

we get here maximum kernels are remaining that is

maximum kernels remaining = 235 - 140

maximum kernels remaining = 85

no of kernels pop in 5 second will be

no of kernels pop = 0.051063 × 85

no of kernels pop = 4.34
