Answer:

  £8400

Step-by-step explanation:

The amount due after t years is ...

  A = P(1 +rt)

  A = £6000(1 + 0.10·4) = £6000·1.40

  A = £8400

Chris pays back £8400 in total.

Answer: 96•(1/4)^n-1

Step-by-step explanation:

Answer:it’s 15

Step-by-step explanation:because think about it if it was 12 it wouldn’t be 60% it would be 70%

8w + 4 > 12

       -4    -4

8w > 8

/         /

8        8

w > 1

W is anything less than 1.

8w + 4 > 12

      - 4   - 4        subtract -4 to both sides.

_________

[tex]\frac{8w}{8}[/tex] > [tex]\frac{8}{8}[/tex]      divide 8 to both sides, 8's will cancel on the left side.

[tex]w[/tex] > [tex]1[/tex]

Answer:

45 is the answer

Step-by-step explanation:

first you have to know the sum of interior angle of that pentagon (540)

then add the all angle.

148 + x + 112 + 90 + 3x + 10 = 540.

or, 360 + 4x = 540

or, 4x = 540 - 360

or, 4x = 180

or, x = 180/4

or, x = 45

hope it will help you☺✌

Answer: 2x^2t+7xy

Step-by-step explanation:

Answer:

8.57

Step-by-step explanation:

We can calculate the value of x using similarity ratio

11/7 = (15 + x)/(15) cross multiply expressions

105 × 7x = 165 subtract 105 from both sides

7x = 60 divide both sides by 7

x = 8.57 approximately

Answer: $187.53 with the 6% discount.

Answer:

y=23x-8

Step-by-step explanation:

Use the formula y=mx+b

y-intercept is b which is -8

the slope is m which is in this case 23

Easy peasy!

The Surface area of the pyramid  is 68 square cm

The total surface area is the area of all the triangles

Area of a triangle = 0.5bh

b is the base

h is the height

Given te followin

b = 6cm

h = 5.2cm

Surface area of the pyramid = 5(0.5 * 6 * 5.2)

Surface area of the pyramid = 78 square cm

Hence the Surface area of the pyramid  is 68 square cm

Answer:

There's no solution to this equation, when 2 equations have the same slope but different y-intercepts, they're parallel. This means they never intercept and there is NO solution and we can't solve for x.

Answer:

The first one is 14 the second is 30 and the last one is 10

Answer:

1. d = 14

2. d = 30

3. d = 10

Ex. Divide 6d by 6 and you get d. Divide 84 by 6 and you get 14. d = 14

Answer:

The roots are y=2, y=-2 and y=7/4

Step-by-step explanation:

4y^3-7y^2+28=16y =0

subtract 16y from both sides

4y^3 -7y^2 - 16y +28 =0

Factor by Grouping

(4y^3 -7y^2) (-16y +28) =0

Greatest common factor

y^2(4y-7) -4(4y-7)

take y^2 and -4 as well as the repeated 4y-7

(4y-7) (-4+y^2)

change -4 to -2^2

(4y-7) (-2^2+y^2)

Similify

(4y-7).  (y-2).  (y+2)

y=7/4    y=2    y=-2

Answer: 47 students

Step-by-step explanation:

430 students went on a trip with the majority of them going on buses.

7 students however, had to use cars.

The number of students who used buses are:

= 430 - 7

= 423 students

The number of students in each bus is:

= No. of students taking buses / no. of buses

= 423 / 9 buses

= 47 students

Answer:

X represents the amount of cups of water

Answer:

x represents the number of cups of water.

Step-by-step explanation:

The recipe calls for ¹/₄ cups of lemon juice per 1 cup of water. This means the amount of lemon juice is dependent on the amount of water. In most functions, x is the independent variable and y is the dependent variable. Since the number of cups of lemon juice is dependent on the number of cups of water, the lemon juice represents y...

...and the water represents x.
