Fynjy0 [20]

I think ur question is.. If you are making a certain amount u need 2 1/4 flour.. and u need to make half more than that isn't it?

2 1/4= 2.25

Take half of 2. 25= 1.115

Now add 2.25+1.115=3.365

That means you should take 3 cup and a little more than 1/4 cup of flour..

MAJORR HELP!!!
WINSTONCH [101]

Answer:

a)$1628.90

b)$1647.00

c)$1648.72

Step-by-step explanation:

The question is on compound interest.

The formula to apply here is;

A=P(1+\frac{r}{n} )^{nt}

where

  • P=principal /beginning amount
  • r=interest rate as a decimal
  • n=number of compoundings a year
  • t=total number of years

a) If compounded annually, n=1

p=$1000, r=5%=0.05 t=10

Amount will be;

A=1000(1+\frac{0.05}{1} )^{10} \\\\\\A=1000(1.05)^{10} \\\\\\A=1000*1.6289=1628.90

Amount=$1628.90

b) If compounded monthly, n=12

p=$1000, r=5%=0.05, t=10, n=12

A=1000(1+\frac{0.05}{12} )^{12*10} \\\\\\A=1000(1.0042)^{120} \\\\\\A=1000*1.647=1647

Amount=$1647.00

c)If interest compounded continuously, it means the principal is earning interest constantly and the interest keeps earning on the interest earned.Here the formula to apply is;

A=Pe^rt where e is the mathematical constant e=2.71828182846

Hence the amount will be;

A=Pe^{rt} \\\\\\A=1000*e^{0.05*10} \\\\\\A=1000*2.71828182846^{0.5} \\\\\\A=1648.72

Amount=$1648.72

A right pyramid with a square base has a base edge length of 12 meters and slant height of 6 meters. The apothem is meters. The
Kisachek [45]

Answer:

Apothem: 6m

hypotenuse : slant height : 6√2 m

height :6m

volume: 288m2

Step-by-step explanation:

Hi, the correct values are: (image  attached down below)

Base length= 12m

Slant height  is actually = 6√2

So, to calculate the apothem (AC)we apply the Pythagorean theorem:

AB^2 = AC^2 + BC^2

√AB^2 -BC^2 = AC

AC = √(6√2)^2 - 6^2

AC =6 meters

Hypotenuse of ABC = AB =6√2 meters

Height = AC = 6 meters

Volume:

Volume of a pyramid = 1/3 x base area x height

area of a square = side length ^2 = 12^2

V= 1/3 x 12^2 x 6 =288 m2

Solve the two-step equation.<br><br> 14 = 31.7 – 3x<br><br> What is the solution?
shtirl [24]

Answer:

The answer is 5.9

Step-by-step explanation:

1) Subtract 31.7 from both sides.

14 - 31.7 =  - 3x

2) Simplify 14 - 31.7 to -17.7

- 17.7 =  - 3x

3) Divide both sides by -3.

\frac{ - 17.7}{ - 3}  = x

4) Simplify -17.7/-3 to 5.9

5.9 = x

5) Switch sides.

x = 5.9

Therefor, the answer is x = 5.9.
