Answer:

Laura will pay an interest of  $75,600.

Step-by-step explanation:

Our formula: A = P(1 + rt)

Principal = $105,000

Rate = 6%

Time = 12 years

A (amount)= 105,000(1 + (0.06 × 12)) = 180,600

$180,600 - $105,000 = $75,600.

Answer:

-13

Step-by-step explanation:

Answer:

t = -13

Step-by-step explanation:

2.6 = -0.2t         Equation

2.6 / -0.2 . = -0.2t/-0.2          Divide -0.2 on both sides

t = - 13       Simplify

Answer:

[tex](2x^2+16x+32)\ \text{sq. inches}[/tex]

Step-by-step explanation:

b = h = Base = Height of triangle = [tex](x+4)\ \text{inches}[/tex]

Area of one triangle

[tex]A=\dfrac{1}{2}bh=\dfrac{1}{2}(x+4)(x+4)[/tex]

There are 4 colored triangles so total area of the triangles is

[tex]4A=4\times \dfrac{1}{2}(x+4)(x+4)\\\Rightarrow 4A=2(x+4)^2\\\Rightarrow 4A=2(x^2+8x+16)\\\Rightarrow 4A=2x^2+16x+32[/tex]

The area of the colored triangles is [tex](2x^2+16x+32)\ \text{sq. inches}[/tex]

Answer:

-5,962 m

Step-by-step explanation:

Since the point is below sea level, it will be a negative number as an integer.

it is 5,962 m below sea level, so as an integer, it will be -5,962 m.

So, the elevation as an integer is -5,962 m

Step-by-step explanation:

GCF of 2 prime numbers is always 1, because prime number only have two factors, themselves and 1.

LCM of 2 prime numbers will be simply multiplying them together.

Sasha can do that by; finding the HCM of two factors.

Razi will tell Jake to find the LCM you have to find the least common factor of the numbers,and then that's your answer.

Hope this helps:)!

Answer:

5y^3 - 7y^2 - 97y + 2   <<<< Answer

Step-by-step explanation:

(у- 2)(5у2 + 3y - 1)

Multiply the three terms by y

5y^2 * y + 3y * y - 1*y = 5y^3 + 3y^2 - y

Multiply the three terms by - 2

-2*5y^2 -2*3y - 2*-1

-10y^2 - 6y + 2

Now combine the like terms

5y^3 + 3y^2 - 10y^2 - y - 6y + 2

5y^3 - 7y^2 - 97y + 2

Answer:

21 minutes

Step-by-step explanation:

Using the formula to calculate the time expressed as;

Speed = Distance/Time

Given:

Distance = 7/8 miles

Speed = 2 1/2 mi/hr

Required

Time in minutes

Substitute the given values into the formula;

Recall that:

S = D/T

T = D/S

Time = 7/8 ÷ 2 1/2

Time = 7/8 ÷ 5/2

Time = 7/8 * 2/5

Time = 7/4 * 1/5

Time = 7/20 hour

Since 1 hour = 60 minutes

7/20 hour = (7/20 * 60)minutes

7/20 hour = 7 * 3

7/20 hour = 21 minutes

Therefore it will take them 21 minutes to get to the campsite

Answer:

$12.65

Step-by-step explanation:

Given that the wall is 23 feet long and 8 feet high.

As the wall is rectangular, so the area of the wall,

A=23x8=184 square feet.

As a gallon of paint costs $11 and covers 320 square feet of area, so

Cost of paint for 1 square foot area = $ 11/320 per square foot.

Cost for 1 coat of paint = $ (11/320)x184

Cost for 2 coat of paint = $ (11/320)x184x2= $ 12.65

Hence, cost requires for 2 coats of paint is $ 12.65.

Answer:

a(45) =-209

Step-by-step explanation:

a(n) = a +(n-1)d

d=-6

we have to get a1

By using:

a(10) = a1 +(10-1)-6=1

a(10) = a1 +(9)-6 =1

          a1  =1+54=55

So:a(45) = 55 +(45-1)-6=-209

Answer:

x = 1/2

y = 4

Step-by-step explanation:

4x - y = -2     --------------------(I)

2x + 3y = 13 --------------------(II)

Multiply equation (I) by 3 and then add

(I)*3         12x - 3y = -6

(II)             2x  + 3y = 13           {Now add and so y will be eliminated}

               14x         = 7

                          x = 7/14

x = 1/2

Plugin x = 1/2  in equation (I)

[tex]4*\frac{1}{2}-y = -2[/tex]

  2 - y = -2

     -y  = -2 - 2

     -y = -4      

   y = 4

Answer:

x=1/2

y=4

Step-by-step explanation:

4x-y=-2

-y=-4x-2

y=4x+2

2x+3y=13

2x+3(4x+2)=13

2x+12x+6=13

14x=7

x=1/2

y=4x+2

y=4(1/2)+2

y=2+2

Y=4

Answer:

x=10

Step-by-step explanation:

5x+17 = 67

The angles are vertical angles which means they are equal.  This means the arc lengths are equal

5x+17-17 = 67-17

5x = 50

5x/5 = 50/5

x =10

Answer:

$545.00

Step-by-step explanation:

250.7 / 23 = 10.9

$10.9 is the cost of every lb of onions.

Then we multiply 10.9 by 50 because there are 50 lbs. like this

10.9 * 50 = 545

So $545.00 is our answer.
