Step-by-step explanation:

√52 - t = 72

t = 72 + √52

t= 72 + √(13•4)

t= 72 + 2√13

Answer:

[tex]t = 2 \sqrt{13} - 72[/tex]

Step-by-step explanation:

[tex] \sqrt{52} - t = 72 \\ t = \sqrt{52} - 72 \\ \sqrt{52 } = 2 \sqrt{13} \\ t = 2 \sqrt{13} - 72[/tex]

Answer:

29

Step-by-step explanation:

if you take 70 and divide it by 2 (cuz there are 2 People) then subtract 6 (because ones 6 years older) then you get 29

70/2=35-6= 29

Answer:

The rate is 6.94 %

Step-by-step explanation:

Given;

Amount borrowed by Fred to  start up the e-commerce, P = 15000

time of investment, t = 12 years

interest, I = 18000

The rate is given by the following equation;

P = IRt

R = P / It

where;

R is the rate

P is the principal

I is the interest

t is the time

R = (15000) / (18000 x 12)

R = 0.0694

R = 6.94 %

Therefore, the rate is 6.94 %

Answer:

The length of the rectangle is 27 ft.

Step-by-step explanation:

To determine the length of the rectangle, we will first determine the value of x.

From the question,

The length of the rectangle is 2x + 16

The width is 3x - 1

and the perimeter is 85 ft

From the formula for perimeter of a rectangle which is given by

P = 2(l+w)

Where P is the perimeter

l is the length

and w is the width

Then, we can then write that

85 = 2(2x+16 + 3x - 1)

85 = 2(5x + 15)

85 = 10x + 30

10x = 85 - 30

10x = 55

x = 55/10

x = 5.5 ft

Since the length of the rectangle is 2x+16, substitute the value of x

Therefore

l = 2x + 16

l = 2(5.5) + 16

l = 11 + 16

l = 27 ft

Hence, the length of the rectangle is 27 ft.

Answer:

Step-by-step explanation:

A suitable calculator can compute the determinant for you. It is ...

  D = 9

Then the values of x, y, z are ...

  (x, y, z) = (Dx, Dy, Dz)/D = (18/8, 27/9, -36/9)

  (x, y, z) = (2, 3, -4)

Answer:

one interior angle 135

one exterior angle 45

Step-by-step explanation:

Total measure of all angles in a 8 sided regular polygon = (n - 2)* 180

                   = ( 8 - 2 ) * 180

                   = 6 * 180

                   = 1080

Measurement of one interior angle = 1080 / 8 = 135

Interior angle and exterior angle make linear pair.

Measurement of one exterior angle = 180 - 135 =  45                                                                                      

A mathematical sentence with an equal sign is called an EQUATION.  It is a relationship showing that two expressions have the same value.  

16 ounces = 1 pound,3(x-5)=16, and 3(2) + 7 = 16-3

Answer:

The maximum height is the y-value of the vertex.

h(t) = -4.9t² + 20t + 65

     a=-4.9   b=20  c=65

h(2) = -4.9(2)² + 20(2) + 65

     = -19.6 + 40 + 65

     = 85.4

Answer:

  5.9%

Step-by-step explanation:

The interest rate formula is useful:

  I = Prt . . . . interest on amount P at rate r for t years

  2950 = 5000·r·10

  r = 2950/50000 = 0.059 = 5.9%

The bank pays 5.9% interest.
