1 1/2 cups vegetable oil is needed. You're tripling the recipe, so you put 1/2 cup and 1/2 cup together to get one, but you still need one more half cup. The answer is 1 1/2 cups

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

Find ""k"" so that the 58 unit diagonal of a rectangle can have an aspect ratio of 15:8. Then find the length and width of the r

irina [24]

Step-by-step explanation:

The area of any 2-d quadrilateral is equal to the base of the shape times the height, though we can just sub in length and width here. The key bits of information here is the aspect ratio (4:3) and the given area (300 in^2).

So far this gives us L∗W=300in2

Now, the aspect ratio given implies for every 4 inches in length, there will be 3 inches in width. This allows us to factor out a 4 and a 3 from the Length and Width respectively and give them the same constant variable, like so:

4x∗3x=300in2

Now, some might be tempted to go ahead with 12x here, but let’s expand the left side out to see what’s really going on:

4∗x∗3∗x=300in2

From here, let’s resolve like terms Our constants will multiply together and give us 12, and x * x of course gives us x^2 to give us the following:

12x2=300in2

From here, simply divide through by 12 to isolate x on one side,x2=25

And finally take the square root of both sides to work out what your common factor is,

x=5

Now that we have out common factor, let’s plug it back into our original formula to find our Length and Width, like so.

(4∗5)in∗(3∗5)in=300in2

20in∗15in=300in2

Therefore, the Length of our rectangle is 20in, and the Width of our rectangle is 15in

I am a figure with six layers .each of my layers is the same.my bottom layer has a perimeter of 28 units and my volume is betwee

juin [17]

"I am a figure with six layers .each of my layers is the same."---> using this sentences, you can conclude that the shape is cube because cube made of 6 similar square.

<span>my bottom layer has a perimeter of 28 units ---> Using this sentences, you can know the square perimeter is 28. Then the square side would be:
square perimeter= 4* side
28= 4* sides
side= 7

Then, the volume of the cube would be:
cube volume= side^3
cube volume= 7^3= 343 cubic units

I think there is a typo somewhere in this question. The calculation should be true, but it is not in 200-300 range. The volume that in 200-300 would be when the side is 6 unit(volume=216), but the perimeter should be 24 not 28.
If the perimeter 28, volume= </span>343 <span>
If the perimeter 24, volume= 216</span>
