Pls help and show workings
Options
A. 14
B. 36
C. 54
D. 90
Answer:
(C). 54°
Step-by-step explanation:
m∠3 + m∠4 = 90°
m∠1 = m∠4 = 2x + 8
(4x - 2)° + (2x + 8)° = 90°
4x - 2 + 2x + 8 = 90
6x + 6 = 90
6x = 84
x = 14
m∠6 = m∠3 = 4(14) - 2 = 54°

C) 45°, 135°
D) 30°, 120°
Answer:
A and C
Step-by-step explanation:

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

Points A and C are vertices of a cube with a side length of 2 cm, and B is the point of the intersection of the diagonals of one face of the cube, as shown below.
Determine the length of CB.
9514 1404 393
Answer:
CB = √6 cm
Step-by-step explanation:
The diagonal of a square is √2 times the edge length, so the length AB will be (1/2)√2(2 cm) = √2 cm.
Then the length CB is given by the Pythagorean theorem as ...
CB = √(AC^2 +AB^2) = √((2 cm)^2 + (√2 cm)^2) = √(4 +2) cm
CB = √6 cm

Consider I(p) = p(50 - p) , which gives the expected income in dollars from a bungee jump attraction when the ticket price is p dollars. What is I(20)?
Answer:
I(20) is 600 dollars
Step-by-step explanation:
From the given function, I(p) = p(50 - p)
Where I is the income in dollars and p is price dollars.
To determine I(20), that is, to determine the income in dollars when the ticket price is 20 dollars.
From
I(p) = p(50 - p)
When p = 20
Then,
I(20) = 20(50 - 20)
I(20) = 20(30)
I(20) = 20 × 30
I(20) = 600
Hence, I(20) is 600 dollars
That is, the income is 600 dollars when the ticket price is 20 dollars.

Solve the following quadratic equation for all values of x in simplest form.
Answer:
[tex]x=\sqrt{7},\:x=-\sqrt{7}[/tex]
Step-by-step explanation:
Start by rewriting the equation to standard form [tex]ax^2+bx+c=0[/tex].
[tex]5(x^2-10)+5=-10,\\5x^2-50+5=-10,\\5x^2-35=0[/tex].
Factor out the 5, then isolate [tex]x^2[/tex]:
[tex]5x^2-35=0,\\5(x^2-7)=0,\\x^2-7=0,\\x^2=7,\\x=\pm \sqrt{7}.[/tex].
Therefore, the solutions to this quadratic are:
[tex]x=\sqrt{7},\:x=-\sqrt{7}[/tex]

This is a right angle.
Step-by-step explanation:
As you can see below, the angle specified is 90 degrees. That is a right angle.
write a similarly statement comparing the two triangles
Answer:
C. ΔBDC+~+ΔEDA
Step-by-step explanation:
Two triangles are said to be similar if their sides and angles are relation in a definite proportion. So that, comparing the triangles (ΔBDC and ΔEDA) in the given diagram;
<B ~ <E
<C ~ <A
D is a common angle to both triangles (right angle).
Also,
BC ~ EA
DC ~ DA
BD ~ ED
Thus, the statement that compares the two triangles is:
ΔBDC+~+ΔEDA (similarity property)

Complete question :
Aliyah is drawing a ball from one bag and a tile from another bag the first bag contains four green balls and four yellow balls the second bag contains tiles 1 through 5 search
What is the probability that she draws a green ball and a tile numbered with 4?
Answer:
1 / 10
Step-by-step explanation:
Given:
Bag content :
Green balls = 4
Yellow balls = 4
Probability = required outcome / Total possible outcomes
P(drawing a green ball) = 4 / 8 = 1/2
Total number of tiles = 5
P(drawing tile numbered 4) = (number of tiles numbered 4 / total number of tiles) = 1 / 5
P(drawing a green ball) * P(drawing tile numbered 4)
= 1 / 2 * 1 /5
= 1 / 10

In 1989, a baseball card was purchased for $6. Today, the value of the baseball card has increased by 425%. What is the current value of the baseball card?
Answer: $31.50
Step-by-step explanation:
We are told that the price of a baseball card was purchased for $6 but that the value of the baseball card has increased by 425%.
The current value of the baseball card would be:
= $6 + (425% × $6)
= $6 + (425/100 × $6)
= $6 + (4.25 × $6)
= $6 + $25.5
= $31.50

Answer:
x = 45°
y = 90°
Step-by-step explanation:
Angles in a Triangle
The sum of the internal angles in a triangle is 180°.
On the other hand, the tick marks on the triangle tell us it's an isosceles triangle, thus the angle formed at both sides of the triangle is x.
Finally, angle x and 135° are a linear pair that always add up to 180°, thus
x = 180 - 135 = 45
x = 45°
The angle y can be found by completing the measure needed to 180°:
x + x + y = 180
y = 180 - 2x = 180 - 90
y = 90°
