a right angled triangle has sides which are 2cm and 7cm shorter than its hypotenuse find the length of the hypoenuse

Answers

Answer 1

Answer:

The length of the hypotenuse side is (9 + 2·√7) cm

Step-by-step explanation:

The given parameters of the triangle are;

The type f triangle = Right triangle

The length of the sides 2 cm and 7 cm shorter than the hypotenuse

Let 'h' represent the length of the hypotenuse side of the triangle, in centimeters we have;

The length of one side of the right triangle = (h - 2) cm

The length of the other side of the right triangle = (h - 7) cm

By Pythagoras's theorem, we have;

h² = (h - 2)² + (h - 7)²

Using search function on the internet, we have;

h² = (h - 2)² + (h - 7)² = 2·h² - 18·h + 53

∴ h² = 2·h² - 18·h + 53

∴ 2·h² - 18·h + 53 = h²

h² - 18·h + 53 = 0

53 is a prime number, therefore, by the quadratic formula, we have;

h = (18 ± √((-18)² - 4×1×53))/(2 × 1)

h = 9 + 2·√7 cm ≈ 14.29 cm or h = 9 - 2·√7 ≈ 3.71

However, given that one of the side is 7 cm shorter than the hypotenuse, for all the sides to remain positive, we have h = 9 + 2·√7 cm ≈ 14.29 cm , because for h ≈ 3.71 cm, we have;

The length of the other side = (h - 7) cm ≈ (3.71 - 7) cm ≈ -3.29 cm which is not possible for a real triangle

Therefore, the length of the hypotenuse side, h = 9 + 2·√7 cm ≈ 14.29 cm.

You have deposited SEK 10,000 in an account that gives 2% interest every year. How much have you received in interest after two years?

Answers

Answer:

404

Step-by-step explanation:

2% of 10000 = 200 in the first year, setting your account to 10200

2% of 10200 = 204 in the second year, setting your account to 10404

In the total of 2 years, you received 404 extra

Answer:

Deposite amount (P) = 10000

Interest ( R)    = 2%

Years (T) = 2

Formula

S.I =PRT÷100

S.I =10000×2×2÷100

S.I =40000÷100

S.I =400

You have received interest after 2 years =400

if 4x-y/2x+y=5/3, then x/y=?

Answers

Answer:

[tex]\frac{x}{y}[/tex] = 4

Step-by-step explanation:

Expressing in fractional form, that is

[tex]\frac{4x-y}{2x+y}[/tex] = [tex]\frac{5}{3}[/tex] ( cross- multiply )

3(4x - y) = 5(2x + y) ← distribute both sides

12x - 3y = 10x + 5y ( subtract 10x from both sides )

2x - 3y = 5y ( add 3y to both sides )

2x = 8y ( divide both sides by 2 )

x = 4y ( divide both sides by y )

[tex]\frac{x}{y}[/tex] = 4

Answer:

[tex] \boxed{ \frac{x}{y} = 4}[/tex]

Step-by-step explanation:

[tex]if \: \frac{4x-y}{2x+y}=\frac{5}{3}, \: then \: \frac{x}{y} = : \\ 3(4x - y) = 5(2x + y) \\ 12x - 3y = 10x + 5y \\ 2x = 8y \\ \frac{2x}{y} = 8 \\ \frac{x}{y} = 4[/tex]

C warmer in Tucson than it was in Minneapolis. If the temperatures in Tucson and Minneapolis are opposites, what is the temperature in Tucson?

PLEASE ANSWER QUICK!!!!!!!!!

Answers

Answer:

[tex]T^\circ = -12^\circ[/tex]

Step-by-step explanation:

Given

Represent the temperature in Tucson with T and that in Minneapolis with M.

From the first statement, we have:

[tex]T^\circ = M^\circ - 24^\circ[/tex]

From the second, we have:

[tex]T^\circ = -M^\circ[/tex] or [tex]M^\circ = -T^\circ[/tex] --- i.e. both are opposite numbers

Required

Find T

To calculate T, substitute -T for M in [tex]T^\circ = M^\circ - 24^\circ[/tex]

This gives:

[tex]T^\circ = -T^\circ - 24^\circ[/tex]

Collect Like Terms

[tex]T^\circ +T^\circ =- 24^\circ[/tex]

[tex]2T^\circ =- 24^\circ[/tex]

Make T the subject

[tex]T^\circ =- 24^\circ/2[/tex]

[tex]T^\circ = -12^\circ[/tex]

Hence, the temperature in Tucson is [tex]-12^\circ[/tex]

Answers

Given:

The pair of expressions in the options.

To find:

The pair that shows equivalent expressions.

Solution:

We have,

[tex]2\left(\dfrac{2}{5}x+2\right)[/tex]

By using distributive property, we get

[tex]2\left(\dfrac{2}{5}x+2\right)=2\left(\dfrac{2}{5}x\right)+2(2)[/tex]

[tex]2\left(\dfrac{2}{5}x+2\right)=\dfrac{4}{5}x+4[/tex]

So, option A is incorrect and option B is correct.

We have,

[tex]2\left(\dfrac{2}{5}x+4\right)[/tex]

By using distributive property, we get

[tex]2\left(\dfrac{2}{5}x+4\right)=2\left(\dfrac{2}{5}x\right)+2(4)[/tex]

[tex]2\left(\dfrac{2}{5}x+4\right)=\dfrac{4}{5}x+8[/tex]

So, options C and D both are incorrect.

Therefore, the correct option is B.

The correct pair of equivalents expressions is B.

Multiplication of expressions

To solve the question, one must have knowledge about the multiplication of expressions.

When you have an expression being multiplied by a value, you multiply all the terms of the expression by that value, so that:

                                     [tex]a (x + y) = ax + ay[/tex]

Thus, performing this multiplication for all alternatives we have:

a) [tex]2 (\frac{2}{5}x + 2) = \frac{4}{5}x + 4[/tex]

b) [tex]2 (\frac{2}{5}x + 2) = \frac{4}{5}x + 4[/tex]

c) [tex]2 (\frac{2}{5}x + 4) = \frac{4}{5}x + 8[/tex]

d) [tex]2 (\frac{2}{5}x + 2) = \frac{4}{5}x + 8[/tex]

So, the only expression that correctly corresponds to the answer is that of alternative B.

Graph quadrilateral abcd whose vertex matrix is shown below. Then graph the dilation of quadrilateral abcd with a scale factor of 3 on the same coordinated grid. Quadrilateral abcd with vertex matrix -1 5 5 -4
2 5 3 -1

Answers

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation is reflection, translation, rotation and dilation.

Dilation is the increase or decrease in size of an object.

Given the vertex matrix of quadrilateral ABCD as:

[tex]\left[\begin{array}{cccc}-1&5&5&-4\\2&5&3&-1\end{array}\right][/tex]

Therefore the vertex of quadrilateral ABCD is at A(-1, 2), B(5, 5), C(5, 3) and D(-4, -1).

Quadrilateral ABCD is dilated by a scale factor of 3 to produce quadrilateral A'B'C'D'.

Hence, the vertex matrix of quadrilateral A'B'C'D' is:

[tex]3\left[\begin{array}{cccc}-1&5&5&-4\\2&5&3&-1\end{array}\right]=\left[\begin{array}{cccc}-3&15&15&-20\\6&15&9&-3\end{array}\right][/tex]

Therefore the vertex of quadrilateral A'B'C'D' is at A'(-3, 6), B'(15, 15), C'(15, 9) and D'(-20, -3).

The correct option is figure A
