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.

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:
y = 7x + 5
because, it adds 7 tiles in every new figure.
The equation is y = 7x +5.
Answer is y = 7x +5
A rectangular prism has a width of x^2 inches, A length of xy^2 inches, and a height of y^2 inches. Which expression represents the volume in cubic inches of this rectangular prism
Answer:
[tex]Volume = x^3y^4[/tex]
Step-by-step explanation:
Given
[tex]Length = xy^2[/tex]
[tex]Height = y^2[/tex]
[tex]Width = x^2[/tex]
Required
Determine the volume
The volume is calculated as:
[tex]Volume = Length * Width * Height[/tex]
[tex]Volume = xy^2 * x^2 * y^2[/tex]
This gives:
[tex]Volume = x^3y^4[/tex]

The perimeter of a square of side 5 cm is 25 cm.
O True
O Falsethe perimeter of a circle
Answer:
false
Step-by-step explanation:
I would assume false as if each of the fours sides of the square are 5 cm, then doing the equation 5×4 (unsing 4 for the each of the congruent sides) would give up 20 cm.
Sharmila had 5/6 portion of the cake. She gave 2/6 portion of the whole cake to
her brother, then how much cake will remain with her?
Answer: [tex]\dfrac{3}{6}[/tex]
Step-by-step explanation:
Given
Sharmila has [tex]\frac{5}{6}[/tex] portion of cake
she gave [tex]\frac{2}{6}[/tex] portion to her brother
The remaining cake is given by
[tex]\Rightarrow \dfrac{5}{6}-\dfrac{2}{6}=\dfrac{5-2}{6}\\\\\Rightarrow \dfrac{3}{6}[/tex]
i.e. [tex]\frac{3}{6}[/tex] portion of cake will remain with her

Answer:
19. RE = 12
20. EB = 24
Step-by-step explanation:
19. Determination of RE
HE = 24
RE =?
From the diagram given above, we can conclude that:
HE = 2RE
24 = 2RE
Divide both side by 2
RE = 24 / 2
RE = 12
20. Determination of EB.
YB = 12
EB =.?
From the diagram given above, we can conclude that:
EB = YB
EB = 2 × 12
EB = 24

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

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)"

i got a question where it gave the slope of -1/2 and a point of (-10,3) i need to find the equation of the line
9514 1404 393
Answer:
y -3 = -1/2(x +10)
Step-by-step explanation:
Given a point and a slope, it is reasonable to use the point-slope form of the equation for a line.
y -k = m(x -h) . . . . . . . . line with slope m through point (h, k)
Your line has slope m = -1/2 through point (h, k) = (-10, 3). Putting these values into the appropriate form your equation is ...
y -3 = -1/2(x +10) . . . . point-slope form equation
__
y = -1/2x -5 +3 . . . . eliminate parentheses, add 3
y = -1/2x -2 . . . . . . . . . slope-intercept form equation
