Figure o of a tile pattern has 3 tiles. This pattern grows
by 5 tiles each figure.
Answer:
Figure 0 = 5 tiles
Figure 1 = 5 + 7 = 12 tiles
So, the equation is:

because, it adds 7 tiles in every new figure.
The equation is y = 7x +5.
Answer is y = 7x +5
If an equilateral triangle has a height of 8 metres find the length of each side. Round your answer to 2 decimal places.
Answer:
9.24 m to 2 DP's.
Step-by-step explanation:
Consider the right triangle formed from a side , altitude and 1/2 the base.
By pythagoras:
x^2 = 8^2 + (0.5x)^2 where x is the length of each side.
x^2 - 0.25x^2 = 64
0.75x^2 = 64
x^2 = 64/0.75 = 85.3333.
x = 9.2376 m.

double the sum of a number and 3
Hey there!
Your answer is 2(n + 3)
"Double" represents multiplying by two. Also, "sum of a number and 3" represents the addition of 3 and a number, so we could put "n + 3". Since we are doubling the sum, it would be "2(n + 3)"

in
Answer:
172.27 in
Step-by-step explanation:
Apply the Sine Rule
Sine Rule is given as:
[tex] \frac{a}{sin(A)} = \frac{b}{sin(B)} = \frac{c}{sin(C)} [/tex]
c = x = ?
C = 180 - (52 + 48) = 80° (sum of triangle)
b = 130 in.
B = 48°
Plug in the values
[tex] \frac{130}{sin(48)} = \frac{x}{sin(80)} [/tex]
Multiply both sides by sin(80)
[tex] \frac{130*sin(80)}{sin(48)} = x [/tex]
172.274641 = x
x = 172.27 in. (to 2 decimal places)

Two cars start towards each other from points 200 miles apart. One car travels at 40 miles
per hours and the other travel at 35 miles an hour. How far apart will the two cars be after
four hours of continuous travelling?
(a) 20
(b) 40
(c) 75
(d) 100
Answer:
D) 100
Step-by-step explanation:
Solution: After four hours, one car travels 40 x 4 = 160 km, and the other car travels 35 x 4 = 140 km. Therefore, the two cars are 160 + 140 - 200 = 100 km apart

What is the base in the given problem? The 20% of 35 boys in the class which is 7, wear eyeglasses.
Answer:
the base of the given problem is 7
Step-by-step explanation:
The computation of the base in the given problem is shown below:
Given that
20% of 35 boys in the class wear eyeclasses
So if we solve this
The value would be
= 20% of 35 boys
= 20% × 35
= 7
Hence, the base of the given problem is 7
The same would be considered
