Answer:

The dimensions are 7.4m by 15.1 m (to the nearest tenth).

Step-by-step explanation:

Area = length * width

If the width = x then the length = 3x - 7 so

Area x(3x - 7) = 111

3x^2 - 7x - 111 = 0

Using the quadratic formula:

x  = [ -(-7) +/- √((-7)^2 - 4*3*-111)] / (2*3)

x =  7.36, -5.03.

The width must be positive s it is 7.36 m.

The length = 3(7.36) - 7

= 15.08 m.

Answer:

Salary is 7000

He saved 2800 in may

The monthly salary of the Wai keong will be $7,000 and the amount of his savings will be $2,800.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Wai keong's monthly salary is twice the amount he save in April he save $3500 in April.

Let x be the monthly salary of the Wai keong.

Then the equation will be

x = 2 × $3500

x = $7,000

The monthly salary is $7,000.

In may, he saved $4200 less than the amount he spent.

Then the amount of money that he can save will be

⇒ $7,000 - $4,200

⇒ $2,800

The monthly salary of the Wai keong will be $7,000 and the amount of his savings will be $2,800.

c. 0.55

Step-by-step explanation:

A chosen acre of land is forested and not forested are complimentary event , so let :

F = Chosen land is forested

F = Chosen land is not forested

....and we know  F+F = S

where S is sample space and we know probability ocer whole sample space is 1 , that is P(S)=1 , and we know F and F are independent so

P(F+F) = P(S)

P(F) + P(F)=1

We have given that probability of forest land in randomly chosen an acre land in Canada have probability 0.45 so P(F)=0.45 so ,

0.45 + P(F) = 1

P(F) = 1 - 0.45

P(F) = 0.55

Hence, the probability that the chosen acre is not forested is 0.55

4n = - 6

n = - 6/4

n = - 3/2

And that it

Answer:

n = 1.5

Step-by-step explanation:

So, you left off on where we subtracted 40 from both sides.

34 - 40 = -6

4n = -6

Now, divide both sides by 4 to ultimately isolate the variable:

4n/4 = -6/4

Therefore your answer is -1.5

Step-by-step explanation:

There 3 different flavors of ice-cream available and 5 different toppings are available.

In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.

The formula to compute the combinations of k items from n is given by the formula:

[tex]{n\choose k}=\frac{n!}{k!\cdot (n-k)!}[/tex]

(a)

Compute the number of possible sundaes that can be made with one flavor  and three different toppings as follows:

[tex]\#\text{Sundaes}=\#\text{Ways to select 1 flavor}\times \#\text{Ways to select 3 toppings}[/tex]

                [tex]={3\choose 1}\times {5\choose 3}\\\\=3\times 10\\\\=30[/tex]

(b)

Compute the number of possible sundaes that can be made if there are three scoops of each ice cream and two different toppings as follows:

[tex]\#\text{Sundaes}=\#\text{Ways to select 1 flavor}\times \#\text{Ways to select 3 toppings}[/tex]

                [tex]=1\times {5\choose 2}\\\\=1\times 10\\\\=10[/tex]

Answer:

Step-by-step explanation: they will form a straight line, passing through the origin.

let the radius of the first one be r

then the first point is (2r, 2πr)

slope of line passing through (0,0) and (2r, 2πr)

= (2πr)/(2r)

= π

The slope of the resulting line is π.

The slope of a line is a number that describes both the direction and the steepness of the line.

Given that, A company logo has 4 concentric circles. you graph the points (diameter, circumference) and connect them with a line.

They will form a straight line, passing through the origin.

Let the radius of the first one be r

Then the first point is (2r, 2πr)

Slope of line passing through (0,0) and (2r, 2πr)

= (2πr)/(2r)

= π

Hence, The slope of the resulting line is π.

Step-by-step explanation:

Total surface area of the given triangular prism is 144 centimeter square

The surface area of a solid object is a measure of the total area that the surface of the object occupies

A triangular prism is a three-sided prism; it is a polyhedron made of a triangular base, a translated copy, and 3 faces joining corresponding sides

Given figure is a right angled triangular prism

Total surface area of the right angle triangular prism = (x + y + h )L + b × h

Here,

x= 8 cm

y= 10 cm

h= 6 cm

L= 4 cm

b= 8 cm

Substitute the values in the equation

Total surface area = (8 + 10 +6)4 + 8×6= 144 centimeter square

Hence, the total surface area of the triangular prism is 144 centimeter square

The measure of the angle x in the given figure is 142°.

When two lines meeting at a point, it will form angle.

We know that, if two lines meeting at a point and forms a straight line then the angle on the either side of the line is 180°.

Here, in the given figure: (x + 38°) = 180°
