Write the problem as follows:

$\text{21:15 - 08:30}$

Note that the maximum value for the minutes value is 59, as 60 minutes would convert into an hour.

Because we're subtracting 30 minutes from 15, convert an hour into 60 minutes for the first term, then subtract:

$\text{20:75 - 08:30 = \boxed{12:45}}$

The resulting military time will be 1245.

Circumference of a circle=diameter times pi

50.24=d(3.14)
d=16

radius is half of diameter so radius is 8

Area of a circle=pi(r^2)

(3.14)(8^2)=(3.14)(64)=200.96

Mary used one big bag of flour. She baked four loaves of bread. Then, she used the remaining flour to make 48 muffins. How much

algol [13]

Answer:

Amount of flour in the bag when Mary began = $4x+48y$

Step-by-step explanation:

Given:

Number of baked loaves of bread made from flour = 4

Number of muffins made from flour = 48

To find: Amount of flour in the bag when Mary began

Solution:

Let x denotes amount of flour used to make one baked loave of bread and y denotes amount of flour used to make one muffin.

So,

Amount of flour used to make 4 baked loaves of bread = 4 x

Amount of flour used to make 48 muffins = 48 y

Amount of flour in the bag when Mary began = $4x+48y$

Solve the equation. Round the solution to the nearest tenth . Enter the solution set of the equation . 2P o =P 0 (1.053)^ t

kow [346]

Answer: t= 13.4

Step-by-step explanation:

The given equation is $2P_0=P_0(1.053)^t$

To solve this equation for 't', we first divide both sides by $P_0$ , we get

$2=(1.053)^t$

Taking log on both the sides, we get

$\log 2= \log(1.053)^t$

Since $\log a^b=b\log a$

Then,

$\log 2= t\log1.053\\\\\Rightarrow0.30103=t(0.02243)\\\\\Rightarrow t=\dfrac{0.30103}{0.02243}\\\\\Rightarrow t=13.4208649131\approx13.4$

Hence, the value of t is 13.4.
