Which equation can be used to find d, the number of dollar coins Giuliana has?

Answer:

Lie #3

b^6 is not b^8

Step-by-step explanation:

All the problems use the quotient rule of exponents, which says that you subtract the exponents when dividing by the same base.

If we plug in 2 for x on #3, we have

[tex]\frac{b^8}{b^2}=b^(^8^-^2^)=b^6\\ b^6\neq b^8[/tex]

Furthermore, x would need to be 0 to make #3 true since 8-0 = 8

If LMNO is a parallelogram then NM=7=OL and the value of X is 7 unit

What is a Parallelogram?

A quadrilateral having two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size. Additionally, the interior angles that are additional to the transversal on the same side. 360 degrees is the sum of all interior angles.

A parallelepiped is a three-dimensional shape with parallelogram-shaped faces. The base (one of the parallel sides) and height (the distance from top to bottom) of the parallelogram determine its area. A parallelogram's perimeter is determined by the lengths of its four sides.

As it is a parallelogram so, the opposite sides of the parallelogram are equal so NM=OL and ON=LM ,

according to the question ;-

NM = x+5

OL=2x+3

and NM=OL

x+5=2x+3

x=2

So, NM= 7

OL=7

Using the formula of compound interest, the amount accumulated over 4 years is $15,849.46

Compound interest is the interest calculated on the principal and the interest accumulated over the previous period. It is different from simple interest, where interest is not added to the principal while calculating the interest during the next period. In Mathematics, compound interest is usually denoted by C.I.

The formula is often given as;

C.I = P(1 + r/n)^nt

Substituting the values into the formula

C.I = 200(1 + 0.0105/12)^12*4

However, over the period of 4 years, the Principal becomes

Principal = 200 * 4 * 12 = 9600

Rate = 1.05 * 12 = 12.6

C.I = 9600(1 + 12.6/12)^12 * 4

C.I = $15,849.46

Answer:

l =  10 feet

m = 30 feet

n = 25 feet

Total Perimeter = 65 feet

Step-by-step explanation:

The perimeter of a trianlge is the sum of its three sides, and in this case is equal to 65 feet.

65 feet = l + m + n

l + m + n = 65

We also know that:

 l = (1/3)m, and

n = l+m-15

Substitute these definitions of l and n into the original equation:

l + m + n = 65

[(1/3)m] + m + [l+m-15] = 65

[(1/3)m] + m + [[(1/3)m]+m-15] = 65

Simplify:

(1/3)m + m + (1/3)m + m - 15 = 65

2m + (2/3)m = 80

(6/3)m + (2/3)m = 80

(8/3)m = 80

m = 80*(3/8)

m = (10)*(3)

m = 30 feet

Since l = (1/3)m, l = 10 feet

Since n = l+m-15, n = 10 + 30 - 15, or 25 feet

The three sides are

      l:    10 feet

     m:  30 feet

     n:   25 feet

Total = 65 feet

225 km travels in =25 ltr

1 km travel = 225 25

540 km will require = 22525 ×540=60 L

Was this answer helpful?

Answer:

1) 540 km

2) 6 liters of petrol

Step-by-step explanation:

To answer the two questions, it is easiest to fist find the relationship between kilometers (km) and liters of petrol. Since 7 liters (L) results in 315 km, we can find the km/liter petrol conversion factor (converts liters of petrol to km):

(315 km)/(7 liters) = 45 km/L

1) 12 liters times the conversion factor will tell us how many km the motorcycle will travel"

(12 liters)*(45 km/liter) = 540 km [Note that the liters unit cancles, leaving only km]

2) To find the liters of petrol to travel 270 km, we can use the same conversion factor, but now we need to divide to get the units we want, which is km:

(270 km)/(45 km/l) = 6 liters [Note that km cancels and l moves to the top, leaving liters as the only unit.

Solution for the equation x² + 81 = 0 is x =  ± 9i.

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

The given equation is,

x² + 81 = 0

To find the solution of the given equation,

Simplify the equation,

x² = -81

x = √-81

x = ±9√-1
