Answer:
Option A
Step-by-step explanation:
From the triangle given in the picture,
By applying sine rule,
sin(60)° = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{\sqrt{3} }{2}=\frac{a}{7}[/tex]
a = [tex]\frac{7\sqrt{3} }{2}[/tex]
Similarly, by cosine rule,
cos(60)° = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{1}{2}= \frac{b}{7}[/tex]
b = [tex]\frac{7}{2}[/tex]
Therefore, Option A will be the correct option.
3. The floor of building consists of 2000 tiles which are rhombus shaped and
each of its diagonals are 40 cm and 25 cm in length. Find the total cost of
polishing the floor, if the cost per m2 is Rs/5.
Answer:
Total cost of polishing the floor is Rs/500.
Step-by-step explanation:
The floor consists of 2000 tiles which have the shape of a rhombus.
Area of rhombus = [tex]\frac{d_{1} *d_{2} }{2}[/tex]
Where: [tex]d_{1}[/tex] and [tex]d_{2}[/tex] are the diagonals.
Given that:
[tex]d_{1}[/tex] = 40 cm = 0.4 m
[tex]d_{2}[/tex] = 25 cm = 0.25 m
Then,
Area of each tile = [tex]\frac{0.4*0.25}{2}[/tex]
= [tex]\frac{0.1}{2}[/tex]
= 0.05 [tex]m^{2}[/tex]
Area of each tile is 0.05 [tex]m^{2}[/tex].
Since there are 2000 tiles on the floor of the building, then;
Total area covered by the tiles = 0.05 x 2000
= 100 [tex]m^{2}[/tex]
The total cost of polishing the floor = 100 x Rs/5
= Rs/500

A rectangle has a length of x + 5 and a
width of 2x-9. Using the formula for the
perimeter of a rectangle, P = 2L + 2W, write
an expression to represent the perimeter of
the rectangle in simplest form.
Answer:
The end equation you get is p = 6x - 8
Step-by-step explanation:
p = 2l + 2w
p = 2(x + 5) + 2(2x - 9)
p = 2x + 10 + 4x - 18
p = 6x - 8
An expression to represent the perimeter of the rectangle in simplest form is 2(3x-4) meters.
Given that, a rectangle has a length of x + 5 and a width of 2x-9.
What is perimeter of a rectangle?The perimeter of a two-dimensional shape is the total length of the outline. To find the perimeter of a rectangle, we add the lengths of all four sides.
The formula for the perimeter of a rectangle is, P = 2L + 2W,
Now, substitute L=x+5 and W=2x-9 in perimeter formula and simplify,
P=2(x+5)+2(2x-9)
=2x+10+4x-18
=6x-8
=2(3x-4)
Therefore, an expression to represent the perimeter of the rectangle in simplest form is 2(3x-4) meters.

Alistair Inc. shipped 32 packs of batteries to a retail store. Regular packs contain four batteries each, and super packs contain six batteries. A total of 166 batteries were shipped. How many regular packs were sent?
Answer:
Number of regular packs sent = 13
Step-by-step explanation:
Let,
x be the number of regular packs shipped
y be the number of super packs shipped
According to given statement;
x+y=32 Eqn 1
4x+6y=166 Eqn 2
Multiplying Eqn 1 by 4
4(x+y=32)
4x+4y=128 Eqn 3
Subtracting Eqn 3 from Eqn 2
(4x+6y)-(4x+4y)=166-128
4x+6y-4x-4y=38
2y=38
Dividing both sides by 2
[tex]\frac{2y}{2}=\frac{38}{2}\\y=19[/tex]
Putting y=19 in Eqn 1
x+19=32
x=32-19
x= 13
Hence,
Number of regular packs sent = 13

You plan to meet a friend at a local bowling alley on Sunday afternoon. Prior to bowling, you must pay an initial fee of $6.00 to rent shoes and will then pay $4.00 per game you play. Which equation (written in slope-intercept form) best models this scenario? Let y represent your total cost and x represent the number of games you play. Group of answer choices y = 4x + 6 y = 2x + 6 y = 6x + 4 y = 4x
Answer:
[tex]y = 4x + 6[/tex]
Step-by-step explanation:
Given
[tex]Initial\ Fee = \$6.00[/tex]
[tex]Rate = \$4.00[/tex]
Required
Derive the linear equation
Let the number of games be x.
Let the total cost be y
So, if the rate of 1 game is $4
Then x games costs 4x
The total cost (y) is then calculated as:
y = Initial Fee + Cost of x games
Substitute values for initial fee and cost of x games
[tex]y = 6 + 4x[/tex]
Rewrite as:
[tex]y = 4x + 6[/tex]

At the arcade, Sami won 2 blue tickets, 1 yellow ticket, and 3 red tickets for 1500 total points. Jamie won 1 blue ticket, 2 yellow tickets, and 2 red tickets for 1225 total points. Yvonne won 2 blue tickets, 3 yellow tickets, and 1 red ticket for 1200 total points. Write a system of equations to represent this situation. Let b = point value of blue tickets; y = point value of yellow tickets; r = point value of red tickets Create a matrix for your system.
Answer:
[tex]\left[\begin{array}{ccc}2&1&3\\1&2&2\\2&3&1\end{array}\right][/tex] [tex]\left[\begin{array}{c}b&y&r\end{array}\right][/tex] [tex]= \left[\begin{array}{c}1500&1225&1200\end{array}\right][/tex]
Step-by-step explanation:
Given
[tex]b = blue[/tex]
[tex]y = yellow[/tex]
[tex]r = red[/tex]
Required
Represent as a matrix
For Sammy:
[tex]2\ blue + 1\ yellow + 3\ red =1500[/tex]
So, we have:
[tex]2b + 1y + 3r = 1500[/tex]
[tex]2b + y + 3r = 1500[/tex]
For Jamie:
[tex]1\ blue + 2\ yellow + 2\ red =1225[/tex]
So, we have:
[tex]1b + 2y + 2r = 1225[/tex]
[tex]b + 2y + 2r = 1225[/tex]
For Yvonne:
[tex]2\ blue + 3\ yellow + 1\ red =1200[/tex]
So, we have:
[tex]2b + 3y + 1r = 1200[/tex]
[tex]2b + 3y + r = 1200[/tex]
The system of equations are:
[tex]2b + y + 3r = 1500[/tex]
[tex]b + 2y + 2r = 1225[/tex]
[tex]2b + 3y + r = 1200[/tex]
To represent as a matrix, we have:
[tex]\left[\begin{array}{ccc}b_1&y_1&r_1\\b_2&y_2&r_2\\b_3&y_3&r_3\end{array}\right][/tex] [tex]\left[\begin{array}{c}b&y&r\end{array}\right][/tex] [tex]= \left[\begin{array}{c}Total_1&Total_2&Total_3\end{array}\right][/tex]
This gives:
[tex]\left[\begin{array}{ccc}2&1&3\\1&2&2\\2&3&1\end{array}\right][/tex] [tex]\left[\begin{array}{c}b&y&r\end{array}\right][/tex] [tex]= \left[\begin{array}{c}1500&1225&1200\end{array}\right][/tex]
