Answer:

90.7yrs.  

Step-by-step explanation:

Given parameters:

Amount borrowed  = $2450

Interest rate  = 3.5%

Amount repaid = $3221.75

Unknown:

Number of years the load was paid  = ?

Solution:

The formula of simple interest;

    I = PRT

Where I is the interest

           P is the principal

          R is the rate

          T is the time

  To find the interest;

    Interest = Amount paid back - loan  = 3221.75 - 2450  = 771.75

Now;

     P = IRT

     2450  = 771.75 x [tex]\frac{3.5}{100}[/tex]  x T

     2450 = [tex]\frac{2701.25T}{100}[/tex]

    T = [tex]\frac{245000}{2701.125}[/tex]   = 90.7yrs

The number of years of the loan period was 90.7yrs.

Answer:

(C) 350 yards

Step-by-step explanation:

From available information

Mean = 790

1 running back = 1637 yards

Standard deviation above mean = 2.42

Using formula

z =( x - mean)/sd

2.42 = (1637-790)/sd

2.42 = 847/sd

We cross multiply

2.42sd = 847

Divide through by 2.42

Sd = 847/2.42

Sd = standard deviation = 350

So our answer is 350 and therefore option c.

can you go answer my question tho

Step-by-step explanation:

Answer:

remainder = 0

Step-by-step explanation:

Using the remainder theorem

If f(x) is divided by (x - h) then the remainder is f(h)

Here f(x) = x³ - x² - 17x - 15 and h = 5 , thus

f(5) = 5³ - 5² - 17(5) - 15 = 125 - 25 - 85 - 15 = 0 ← remainder

Since remainder is zero then (x - 5) is a factor of f(x)

[tex]40.32cm^{2}[/tex]

Step-by-step explanation

4*1.2=4.8

7*1.2=8.4

8.4*4.8=40.32

A rectangle is a two-dimensional shape where the length and width are different.

The length and width of the larger rectangle are 4.8 cm and 8.4 cm.

The area of the larger rectangle is 40.32 cm².

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

Two similar rectangles:

Smaller rectangles:

Length = 4 cm

Width = 7 cm

Larger rectangles:

Length = 4.8 cm

We need to find the width of the larger rectangle.

Since the two rectangles are similar.

4 cm = 4.8 cm

Multiply 7/4 on both sides.

7/4 x 4cm = 7/4 x 4.8 cm

7 cm = 8.4 cm

Now,

Larger rectangle:

Length = 4.8 cm

Width = 8.4 cm

Now,

The area of the larger rectangle:

Area = Length x width

Area = 4.8 x 8.4

Area = 40.32 cm²

Thus,

The area of the larger rectangle is 40.32 cm².

Answer:

C

Step-by-step explanation:

The easiest way to solve this would be to find the difference between the numbers. We can do [tex]-3-(-9)[/tex] to find the difference of [tex]6[/tex]. We can then make sure this is true for the rest of the sequence by adding 6 to each number.

[tex]-9+6=-3[/tex]

The smallest solution is x=-1

Step-by-step explanation:

Quadratic Equation

We have:

[tex]f(x)=2x+1[/tex]

[tex]g(x)=-(x-1)^2+3[/tex]

We'll find the solutions of f(x)=g(x), or:

[tex]2x+1=-(x-1)^2+3[/tex]

Operating:

[tex]2x+1=-(x^2-2x+1)+3[/tex]

[tex]2x+1=-x^2+2x-1+3[/tex]

Rearranging all terms on the left side:

[tex]2x+1+x^2-2x+1-3=0[/tex]

Simplifying:

[tex]x^2-1=0[/tex]

Since the term with the x is missing, we can solve for x:

[tex]x^2=1\qquad\Rightarrow x=\sqrt{1}=\pm 1[/tex]

There are two solutions:

x=1, x=-1

The smallest solution is x=-1

Answer:

Step-by-step explanation:

My answer is 8!!!

If x is equal to 4 then 5x4=20 because if there is no sign then that means that you have to multiply, then you add 20 and 12 which is equal to 32, And then you simplify 4 which equals 8, or you can think of dividing 32 and 4 which is also 8.
