Emma buys two bus tickets to Bradford. She pays with a £10 note. How much change will she get?

[tex]1. \sf{\ Given : \bigg(\dfrac{10^5}{10^2}\bigg) (10^2)^3}[/tex]

The above expression can be written as :

[tex]\implies \sf{10^{(5-2)}}.10^{(2)(3)}}[/tex]

[tex]\implies \sf{10^{(3)}}.10^{(6)}}[/tex]

As Bases are same, we can add the powers with same base

[tex]\implies \sf{10^{(3 + 6)}}}}[/tex]

[tex]\implies \sf{10^{9}}}}[/tex]

[tex]2. \sf{\ Given : \dfrac{10^5}{10^3.10^8}}[/tex]

The above expression can be written as :

[tex]\implies\sf{\dfrac{10^5}{10^{(3 + 8)}}}[/tex]

[tex]\implies\sf{\dfrac{10^5}{10^{11}}}[/tex]

[tex]\implies\sf{10^{(5 - 11)}}[/tex]

[tex]\implies\sf{10^{-6}}[/tex]

[tex]3. \sf{\ Given : \dfrac{10^{-2}.10^{-3}}{(10^2)^{-5}}}[/tex]

[tex]\implies\sf{\dfrac{10^{(-2 - 3)}}{10^{(2)(-5)}}}[/tex]

[tex]\implies\sf{\dfrac{10^{(-5)}}{10^{(-10)}}}[/tex]

[tex]\implies\sf{10^{(-5 + 10)}}[/tex]

[tex]\implies\sf{10^{5}}[/tex]

[tex]4. \sf{\ Given : (2.5\ x \ 10^8)(8\ x \ 10^3)[/tex]

[tex]\implies \sf{(2.5 \ x \ 8)(10^{(8 + 3)})}[/tex]

[tex]\implies \sf{(20)(10^{11})}[/tex]

[tex]\implies \sf{2 \ x \ 10^{12}}[/tex]

[tex]5. \sf{\ Given : \dfrac{27.8 \ x \ 10^{8}}{25 \ x \ 10^{3}}}[/tex]

[tex]\implies\sf{1.112\ x \ 10^{(8 - 3)}}[/tex]

[tex]\implies\sf{1.112\ x \ 10^{5}}[/tex]

Answer:2

Step-by-step explanation:

Answer:

if the 'a base' is 6.5 & the height is 9 & 'b base' is 18.5, the answer is a = 112.5 cm^3

(A) delta h(t) = 32

Step-by-step explanation:

Average rate of change delta h(t) is given by

[tex]delta \: h(t) = \frac{h(b) - h(a)}{b - a} [/tex]

at t = 0, h(0) = 80

at t = 2, h(2) = -16(4) + 64(2) + 80 = 144

Plugging in the numbers

delta h(t) = (144 - 80)/(2 - 0)

= 32

Answer:

arc AC = 202°

Step-by-step explanation:

Based on the tangent-angle secant rule, the angle formed outside a circle by a secant and a tangent is equal to one-half the difference between the far arc and the near arc.

Thus:

m<P = ½(arc AC - arc CB)

Substitute

78° = ½(arc AC - 46°)

Multiply both sides by 2

2*78 = arc AC - 46

156 = arc AC - 46

Add 46 to both sides

156 + 46 = arc AC

202° = arc AC

arc AC = 202°

Answer:

Cellular respiration is the process responsible for converting chemical energy, and the reactants/products involved in cellular respiration are oxygen, glucose (sugar), carbon dioxide, and water. While the exact steps involved in cellular respiration may vary from species to species, all living organisms perform some type of cellular respiration.

Step-by-step explanation:

YS = 2/3 × ( YV ) *.&.* SV = 1/3 × ( YV )

_____________________________

YS = 2/3 × ( YV )

4x + 14 = 2/3 × ( YV )

Multiply both sides by 3/2

( 4x + 14 ) × 3/2 = ( YV ) × 2/3 × 3/2

YV = 6x + 21 ( ☆ )

¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥

SV = 1/3 × ( YV )

1 + 3x = 1/3 × ( YV )

Multiply both sides by 3

( 1 + 3x ) × 3 = ( YV ) × 1/3 × 3

YV = 9x + 3 ( ♡ )

_____________________________

YV = YV

( ☆ ) = ( ♡ )

6x + 21 = 9x + 3

Subtract both sides 3

6x + 21 - 3 = 9x + 3 - 3

6x + 18 = 9x

Subtract both sides 6x

6x - 6x + 18 = 9x - 6x

18 = 3x

Divide both sides by 3

18 ÷ 3 = 3x ÷ 3

x = 6

₩₩₩₩₩₩₩₩₩₩₩₩₩₩₩₩₩₩

YV = 6x + 21 = 9x + 3

YV = 6(6) + 21 = 9(6) + 3

YV = 57

Answer:

  A  x = 15

Step-by-step explanation:

Lines AB and CD being perpendicular means the angles where they meet are all 90°. The diagonal line divides two of those 90° angles into two parts (each). The whole (90°) is the sum of the parts into which the angle has been divided.

The sum of angles 3 and 4 is 90°. Once you understand this relationship, you can write an equation based on the relationship. The equation can be solved in the usual way.

  (4x +4)° +26° = 90°

  4x = 60 . . . . . . . . . . . . divide by °, subtract 30

  x = 15 . . . . . . . . . . divide by 4

Answer:260000

Step-by-step explanation:

Step-by-step explanation:

Given :-

And we need to find the slope intercept form of the line . The slope intercept form of a line is y = mx + c , where m is the slope and c is the y intercept. Substitute respective values ,

Solution 1 :-

[tex]:\implies[/tex] y = mx + c

[tex]:\implies[/tex] y = 1/4 x + 4

[tex]:\implies[/tex] 4y = x + 16

[tex]:\implies[/tex] x - 4y + 16 = 0

Solution 2 :-

[tex]:\implies[/tex] y - 5 = -4( x +1)

[tex]:\implies[/tex] y -5 = -4x -4

[tex]:\implies[/tex] y = -4x +1
