Answer:

simple ( principal *rate*time)/100.

3500*4*10/100 = 1400 interest

account balance =3500+1400=4900

compound p(1+r)^t

3500(1+.04)^10 =3500* 1.480=5180

interest earned = 5180-3500= 1680

how much more interest. ; 1680-1400=280

Answer:

Step-by-step explanation:

Simple Interest:

Simple Interest formula is S.I. = P × r × t

Interest Eared: $3,500 × 0.04 × 10 = $1,400

Account Balance formula is A = P ( 1 + rt )

Account Balance: $3,500 + $1,400 = $4,900

Compound Interest:

Compound Interest formula: [tex]A =P(1+r)^{t}[/tex]

Account balance: $5,180.85

Interest Earned: $5,180.85 - 3,500.00 = $1,680.85

Explanation:

Less Men, means more Days {Indirect Proportion}

Let the number of days be x then,

27 : 36 :: 18 : x

[Please pay attention, we have written 27 : 36 rather than 36 : 27, in indirect proportion, if you get it then chain rule is clear to you :)]

=>27x = 36 * 18

=> x = 24

So 24 days will be required to get work done by 27 men..

Answer:

36 men can complete work in 18 days

so, one man can complete work in 18×36 days

Therefore, 27 can complete work in 18×36/27 = 24 days

Step-by-step explanation:

Answer:

36°

Step-by-step explanation:

it's the same as the given number.

lines l, m, and n are parallel to each other and the same line is intersecting all three of them. since the 36° angle is in the same placement as the x° angle, they are the same.

Answer:

1. 8.03 x 108 2. 6.8 × 10-9 3. 135,900 4. 2.5x10^-11

Step-by-step explanation:

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 803,000,000New Number: 8.03000000Step 2

Now, to find b, count how many places to the right of the decimal.

New Number:8.03000000Decimal Count:12345678

There are 8 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 8.03 (Please notice any zeroes on the end have been removed)

b = 8

Now the whole thing:

8.03 x 108

Step 4

Check your work:

108 = 100,000,000 x 8.03 = 803,000,000

Answer:

the answer is x=15

Step-by-step explanation:

Answer:

15

Step-by-step explanation:

since angles 84 and 5x + 9 are alternate interior angles they both are equal

i.e

5x +9 = 84

5x = 84 -9

5x = 75

x = 75/5

therefore x = 15

The slope of the parallel line is -3/2

Step-by-step explanation:

Calculate the slope using rise over run then simplify.

-6/4 , -3/2

Answer:

a)

2x/3 = 8. First, multiply both sides by 3 to make 2x = 24. Then, divide both sides by 2: x = 12.

b)

3x/2 = 6. First, multiply both sides by 2 to make 3x = 12. Then, divide both sides by 3: x = 4.

Hope this helps!

Answer:

A.) x = 12

B.) x = 4

Step-by-step explanation:

A.) 2x/3 = 8

First let’s multiply both sides by three to get rid of our division equation,

2x/3 = 8

*3 *3

2x = 24

Now we divide both sides by 2 to single out our variable,

2x = 24

/2 /2

X=12

Let’s check our answer just to be sure this is correct, we do this by plugging in “12” for our x

2(12)/3 = 8

24/3 = 8

8 = 8

Now we know that x = 12 is true,

B.)3x/2 = 6

Again well will multiply both sides by 2 to remove our division equation,

3x/2 = 6

*2 *2

3x = 12

We divide both sides by 3 to remove our coefficient in front of the variable,

3x = 12

/3 /3

x=4

Let’s check our answer once again,

3x/2 = 6

3(4)/2 = 6

12/2 = 6

6 = 6

X = 4 is true

Answer:

Step-by-step explanation:

d = √32.5

860.55 mm

Explanation:

The surface area of an hexagonal prism, also known as an octahedron, is given by the following formula (since we have the apothem):

S= 6*b*(a+h)

where b = is the side of the base, a is the apothem length, and h = the height

S = 6 * 8 * (4√3 + 11) = 48 * 17.92812 = 860.55 sq mm

Could have also have used another formula without the apothem:

S =3 * √3 * b² + 6 * b * h

S = 3 * √3 * 8² + 6 * 8 * 11 = 3√3 * 64 + 528 = 332.55  + 528 = 860.55 sq mm

Remember the PEMDAS rule --> in this case the exponents are first.

[tex]5^7[/tex]= 5*5*5*5*5*5*5 = 78,125

=  [tex]78,125*15-8-5[/tex]

The next step to this problem is multiplication because you are starting from left to right and its after the exponents.
