Answer:

around 6.6 years

Step-by-step explanation:

41,500=14,000*.45*x

41,500=6,300*x

41,000/6,300=x

6.5873=x

6.6=x

What is the perimeter of this figure, to the nearest unit?
lana66690 [7]

Answer:

P=38

Step-by-step explanation:

At this case I would use the circumference formula for the rounded part.

The formula of the circumference is C=2πr.

So... We know that the radius is 5 which is half of the diameter. So... C=2π5 which is C=10π or C=31.4 which we divide by 4 because on the image is 1/4th of a circle and C/4 which C=7.85 so the P of the whole figure is P=10+10+5+5+7.85 which is P=37.85 which will be P=38.

Answer: P=38

An interpretation of that expression is

{( - 1)}^{1}  +   {( - 1)}^{2}  +  {( - 1)}^{3}  +  {( - 1)}^{4}  +  {( - 1)}^{5}  +  {( - 1)}^{6}  +  {( - 1)}^{7}  +  {( - 1)}^{8}  +  {( - 1)}^{9}  +  {( - 1)}^{10}

This expressions results in

- 1 + 1 - 1 + 1 - 1 + 1 - 1 + 1 - 1 + 1 = 0

For exercise, mr.harris walked 1 and 3 fourths miles 5 times last week.how many miles did he walk in all?
RUDIKE [14]
Well, if he walked one and three fourths miles five times, all you have to do is multiply one and three fourths and five to get your answer.

1 \frac{3}{4}*5 \\  \\  \frac{7}{4}* \frac{5}{1}    \\  \\  \frac{7*5}{4*1}  \\  \\  \frac{35}{4} =8 \frac{3}{4}

if a quadratic equation with real coefficients has a discriminant of -36 then what type of roots does it have
Aleks04 [339]

Step-by-step explanation:

We have,

If a quadratic equation with real coefficients has a discriminant of -36.

The general form of quadratic equation is :

ax^2+bx+c=0

The discriminant of this equation is : D=b^2-4ac

If D=0, it will have 1 real roots

If D>0, it will have 2 real roots

If D<0, it will have no real roots

We have,

D = -36 < 0, so, the quadratic equation will have no real roots.

Help i don't get it. I've been trying
ASHA 777 [7]

Answer:

JK = 42 , KL = 78

Step-by-step explanation:

JK + KL = JL , substitute values

4x + 6 + 7x + 15 = 129 , that is

11x + 21 = 120 ( subtract 21 from both sides )

11x = 99 ( divide both sides by 11 )

x = 9

Then

JK = 4x + 6 = 4(9) + 6 = 36 + 6 = 42

KL = 7x + 15 = 7(9) + 15 = 63 + 15 = 78
