Okay can some one tell me where I am going wrong I don't understand how I am getting this wrong

QUESTION: THE LENGTHS OF THE RECTANGLE HAVE BEEN MEASURED TO THE NEAREST TENTH OF A CENTIMETER CALCULATE THE UPPER BOUND FOR THE PERIMETER OF THE RECTANGLE length: 9.8cm width: 4.3 cm

My workings:
1cm=0.05
9.8 - 0.05= 9.75
4.3-0.05= 4.25
9.75+4.25 = 14

Answer: £122.4

Step-by-step explanation:

Given

The rate of interest is 4%

The principal invested is £1500

the time period is 2 years

Compound interest is given by

[tex]C.I.=P(1+r\%)^t-P[/tex]

put values

[tex]C.I.=1500(1+0.04)^2-1500\\C.I.=1500[1.04^2-1]\\C.I.=1500[1.0816-1]\\C.I.=1500\times 0.0816\\C.I.=122.4[/tex]

Therefore, interest earned is £122.4

Step-by-step explanation:

When a transversal line crosses parallel lines, it creates 8 angles. If the transversal crosses at right angles, every one of those angles is a right angle.

If the transversal does not cross at right angles, it creates 4 acute angles and 4 obtuse angles. The acute and obtuse angles are supplementary to each other, since they form linear pairs.

All of the acute angles are congruent, as are all of the obtuse angles. [this is the simplicity of it — only true if the lines are parallel]

__

Different pairs of angles have names. Angles on opposite sides of a point of intersection are "vertical" angles. Angles between the parallel lines are "interior" angles, and those outside are "exterior" angles. Angles on the same side of the transversal are called "same-side" or "consecutive" angles. Angles on opposite sides of the transversal are called "alternate" angles.

Angles in the same direction from the points of intersection (upper-left, for example) are called "corresponding" angles.

__

Angle relationships are often described in the terms described above. For example, every pair of "corresponding angles" is congruent, as are "alternate interior" or "alternate exterior" angles. In any geometry (not just one like this), "vertical angles" are congruent.

_____

You are given the measure of angle 4 (122°). This tells you every obtuse angle in the figure is 122°, and every acute angle in the figure is 180°-122° = 58°. All you need to do to find the angle measures is identify the angle as acute or obtuse.

For justification, you may be expected to determine the relationship of the requested angle to angle 4.

7. ∠8 — part of linear pair; supplementary to ∠4

8. ∠5 — alternate exterior; congruent to ∠4

9. ∠2 — corresponding; congruent to ∠4

10. ∠1 — consecutive exterior; supplementary to ∠4

11. ∠6 — vertical to ∠1*, so the same measure as ∠1

12. ∠7 — vertical to ∠4; congruent to ∠4

__

* angles 1 and 4 have no named relationship. angle 2 is corresponding to angle 4, and angle 5 is alternate exterior with respect to angle 4. Each of those is supplementary to angle 6, so angle 6 is supplementary to angle 4.

Answer:

the 10$ one

Step-by-step explanation:

Answer:

Step-by-step explanation:

There are four points here.  We look at the x-values and identify {2, 1, -2, 1].  This can be reduced to {-2, 1, 2}

Unfortunately, the input '1' shows up twice and thus the relation cannot be a function; we cannot have two different y-values for the same x-value (1).

Answer:

C. 6.6%

Step-by-step explanation:

The probability of an event 'A' occurring, P(A) is given by the ratio of the number of times event A occurs to the some of all possible events

Mathematically, we have;

[tex]The \ probability \ of \ an \ event = \dfrac{The \ number \ of \ the \ required \ outcome}{The \ number \ of \ all \ possible \ outcomes}[/tex]

The number of drivers involved in an accident who are above 75 years = 13,321

The total number of drivers in accidents = (10,034 + 17,173+ 35,712+ 40,322 + 40,937 + 30,355 + 17,246 + 13,321) = 205,100

A 78-year-old is in the age group of 75 and older

∴ The probability that a 78-year-old licensed driver was involved in an accident = The probability that a 75 and older year-old licensed driver was involved in an accident = 13,321/205,100 ≈ 0.06495 = 6.5%

Therefore, the best option is option C. 6.6%

Answer:

(-3,0) ; (1,0)

Step-by-step explanation:

We have to solve the associated equation:

-2x^2 -4x + 6 = 0

-x^2 - 2x + 3 = 0

x^2 + 2x -3 = 0

Δ/4 = 1 + 3 = 4

x1 = -1 + 2 = 1

x2 = -1 -2 = -3

Answer:

Diameter = 2.68cm

Step-by-step explanation:

Circumference of a circle = 2πr

Circumference of a circle = 8.44cm

π = 3.14

r = ?

Circumference of a circle = 2πr

8.44 = 2 * 3.14 * r

8.44 = 6.28r

r = 8.44/6.28

r = 1.3439490445859

Approximately

r = 1.34

Diameter = 2r

Diameter = 2 * 1.34

Diameter = 2.68cm

[tex](5x-3)^{2}[/tex] - (3x+1)(2x-1)

Step-by-step explanation:

Determine the area of the large square: (5x - 3)(5x - 3)

Determine the area of the small rectangle: (3x + 1)(2x -1)

Subtract the area of the small rectangle from the area of the large square to get the area of the shaded region.

Answer:

a) 36

b) 11:5

Step-by-step explanation;

a) let the number of cold stone cones be x

Since the initial ratio is 11:9

we have the ratio of the ice creams as;

11:9 = 44:x

11/9 = 44/x

11 * x = 9 * 44

x = (9 * 44)/11

x = 9 * 4 = 36

b) Now, from 36, we have a number of cold stones as 20

So the ratio now will be;

44:20

and that would be;

11:5

EWWWWWWWWWWWWW UR BI???!!

Step-by-step explanation:

Answer:

b = 60

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

b² + 63² = 87²

b² + 3969 = 7569 ( subtract 3969 from both sides )

b² = 3600 ( take the square root of both sides )

b = [tex]\sqrt{3600}[/tex] = 60
