Answer:

The height h is $5\ cm$

Step-by-step explanation:

we know that

The surface area of the bread is equal to

$SA=2B+Ph\\$

where

B is the area of the base

P is the perimeter of the base

h is the height

In this problem

If fifty percent of the surface area of the bread is crust

then

$2B=Ph\\$

substitute the values

$2(10)(10)=4(10)h\\$

$200=40h\\$

$h=200/40=5\ cm$

Answer:

S(2001) = 19.23

S(2002) = 37.22

Step-by-step explanation:

Given that;

S(t) = 0.73t^2 + 15.8t +2.7

t = 0 corresponding 2000

t = 1 then, its mean year 2001

S(2001) = 0.73(1)^2 + 15.8(1) +2.7

= 0.73 + 15.8 + 2.7

S(2001) = 19.23

also

t = 2 then, it means 2002

S(2002) = 0.73(2)^2 + 15.8(2) +2.7

= 2.92 + 31.6 + 2.7

S(2002) = 37.22

Paul buys a number of large sacks of fertilizer costing $x each

Komok [63]

X times S = $27. X is the cost of the large sacks and S is the amount of sacks. Once they are multiplied it should equal $27. If this is incorrect please let me know so I can try and correct mistakes made.

1st Avenue would be more difficult because it’s rise and run is for every one foot forward it is 3 feet up. Meanwhile avenue 16th would start at (3,1) and the rise and run would be for every 3 feet it would go up 1 foot.

At a carnival, an individual can win a prize by choosing a rubber duck from a pond with "Win" written on the underside of the du

boyakko [2]

Step-by-step explanation:

The probability of success = 8/(8 + 17) = 8/25 = 0.32.

Let X be the random variable denoting the number of successes (number of times the individual won a prize) in four picks.

Hence, X ~ Bin(4, 0.32).

Thus, P(X = 1) = $4C_1=(0.32)(1-0.68)^{4-1}=4C_1(0.32)(0.68)^3$
