I = p * r * t
p = 450
i = interest ??? That's what you are trying to find.
r = 12.1/100 = 0.121
t = 1 year

i = 450 * 0.121 * 1
i = 54.45 dollars.

What is the measure of angle BCD?<br><br> m∠BCD = degrees
ratelena [41]
Angle DAC = 180-25 = 155 degrees
Angle ABC = 180 - 146 = 34 degrees
Angle ADC = 180 - 149 = 31 degrees

ABCD is a quadrilateral and angles in quadrilateral add up to 360 degrees

Angle BCD = 360 - (155 + 34 + 31)
= 360 - 220
= 140 degrees

What is this and how do i solve
Troyanec [42]

Answer:

<h2>x = 20</h2>

Step-by-step explanation:

The angles 7x° and (x + 20)° are supplementary angles.

Supplementary angles add up to 180°.

Therefore we have the equation:

7x + (x + 20) = 180

7x + x + 20 = 180            <em>subtract 20 from both sides</em>

8x = 160         <em>divide both sides by 8</em>

x = 20

The volume of a storage tank is 1695.6 m3. The radius is 6m. How tall is the storage<br> tank?
Andreas93 [3]

Answer:

the storage tank is a cylinder.

The formule to calculate the volume is:

v =\pi{r}^{2}  \times h

h = v \div \pi {r}^{2}

h = 1695.6 \div 36 \times \pi = 14.992

Marine fuel is a combination of gasoline and motor oil. The standard gasoline and oil mixture is about 98% gasoline and about 2%
Georgia [21]

Answer:

0.98g+ 0.02m= 7.1224 gallons standard mixture

0.96g+ 0.04m= 6.25 gallons break oil

3.92 gallons of gasoline  is required for  4 gallons the standard mixture

Step-by-step explanation:

If we have to use 6 gallons of gasoline this means that 98%= 6 gallons and 2% would be 6/98*2

Gasoline: Motor oil

6              :    x

98        : 2

Using the product rule

x= 6*2/98= 0.1224 gallons of motor oil is required.

Let the gasoline be represented by g and motor oil by m then for the standard oil the equation would be

0.98g+ 0.02m= 7.1224 gallons standard mixture

For break in oil

Gasoline: Motor oil

6              :    x

96        : 4

Using the product rule

x= 6*4/96= 0.25 gallons of motor oil is required.

Let the gasoline be represented by g and motor oil by m then for the break oil the equation would be

0.96g+ 0.04m= 6.25 gallons break oil

Part b. For  4 gallons of the "break in" mixture

96% of the 4 gallons of the "break in" mixture is gasoline =  3.84 gallons of gasoline

4% of 4 = 0.16 gallons of motor oil

Now the standard mixture 4 gallons would contain 98 % of gasoline and 2 % of motor oil

98% of 4 gallons= 3.92 gallons of gasoline

2% of  4 gallons= 0.08 gallons of motor oil.
