Answer:

Sara have 11 chapters left to  read.

Step-by-step explanation:

Total chapters Book has = 26

On Monday Sarah read = [tex]\frac{9}{26}\ of \ 26 \ chapters = \frac{9}{26}\times \ 26 \ chapters=9 \ chapters[/tex]

On Tuesday Sarah read = [tex]\frac{6}{26}\ of \ 26 \ chapters = \frac{6}{26}\times \ 26 \ chapters=6 \ chapters[/tex]

Total Chapters read by Sarah = [tex]9+6= 15 \ chapters[/tex]

Chapters left to read by Sarah = [tex]26-15 = 11 \ chapters[/tex]

So, Sara have 11 chapters left to  read.

Answer:

88.76%

Step-by-step explanation:

Given that :

Half life of radium = 1599 years

Percentage that will remain after 275 years

Using the relation :

y = Ae^kt

Where ; A = mass of radium and t = half life = 1599, A = initial mass

By 1599, the mass of radium will be half its initial

Hence,

y = initial / 2 = A /2

A/2 = Ae^kt

To obtain the value of k

0.5 = e^1599k

In0.5 = 1599k

k = (In0.5)/1599

k = - 0.0004335

Hence,

y = Ae^-0.0004335t

Amount of radium. After 275 years : t = 275

y = Ae^-0.0004335*275

y = A0.8876191

y = 0.8876191 of intial amount

Hence, 0.8876191 * 100%

= 88.76%

Answer:

This type of problem can be solved in various ways such as in terms of ratios and fractions, Let us go with fractions.

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, Miami Marlins won 14 of their first 27 games.

So, their win rate in decimal is,

= 14/27.

= 0.518.

∴ In 162 games at the same rate, Miami Marlins will win,

162×0.518.

= 84 games.

So, after playing 162 games they'll win 84games.

Step-by-step explanation:

Subtract 2 from -6, so -6 -2 which gives -8.

Subtract 3 from 1 so, 3-1 = -2.

Step-by-step explanation:

Answer:

BE = 49 cm

Step-by-step explanation:

Use Pythagorean theorem

(hypotenuse)² = (base)² + (leg)²

ΔDEF,

DE² + EF² = FD²

DE² + 63² = 65²

DE² + 3969 = 4225

              DE² = 4225 - 3969

              DE² = 256

             DE = √256 = √(16*16)

DE = 16 cm

ΔCBD,

BC² + BD² = CD²

56² +BD² = 65²

3136 + BD² = 4225

           BD² = 4225 - 3136

           BD² = 1089

          BD = √1089 = √(33*33)

BD = 33 cm

BE = BD + DE

    = 33 + 16

BE = 49 cm

Answer:

it's 19

Step-by-step explanation:

18 - 3 = 15

so the difference between them is 15

so since you wanna fine the "?" on the right, you would add 4+15, which gives you 19

(also 3 and 4 four are only one number apart, so you could have just added (+1) to 18) :)

Answer:

138

Step-by-step explanation:

G + H = 180   {G, H are linear pair}

12x + 6 + 4x - 2 = 180

12x + 4x + 6 - 2  = 180

       16x  + 4      = 180

                    16x = 180 - 4

                   16x = 176

                      x = 176/16

                      x = 11

G = 12x + 6

   = 12*11 + 6

  = 132 + 6

  = 138

Answer:

0.36

Step-by-step explanation:

A= K/B^2

K= A × B^2

K= 1 × 3^2

K= 1×9

K= 9

Therefore if B is 5 then A can be calculated as follows.

K= A × B^2

9= A × 5^2

9= A × 25

9= 25A

A= 9/25

A= 0.36

Hence A is 0.36

Answer:

The value of x that will make this equation true is 50.

The ordered pair (4, -5) satisfies the equation

3x- 2y= 22

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

We have ordered pair (4, -5)

First equation, 2x - 5 y= -30

So, 2(4)- 5(-5)= 8 + 25= 33

Second equation,7 x + 4 y = -19

So, 7(4)+4(-5)= 28 -20= 8

Third equation, 6x - y= -29

So, 6(4) +5= 24+ 5 = 29

Fourth equation, 8 x + 3 y= -37

So, 8(4) + 3(-5)= 32 - 15 = 17

Fifth equation, 3x- 2y= 22

3(4)- 2(-5)= 12 + 10 = 22

sixth equation, 2x+ 9y = -37

2(4) + 9(-5)= -37

seventh equation, 5x- 6y= 49

5(4) - 6(-5)= 20 + 30 = 50

eight equation, x+ 8y= -27

4+ 8(-5)= -36
