An ostrich was 960meters east of its nest. It ran west at a constant velocity for 160seconds. In that time, it ran halfway to its nest. What was its velocity?
Answer is 3 m/s.
Step-by-step explanation:-The ostrich ran at a constant velocity, so it's velocity was :
[tex]velocity = \frac{distance}{time} [/tex]
It is said that the bird ran for 160 seconds and it made it half-way to its nest, so the distance was :
[tex]distance = \frac{960 \: metres}{time} [/tex]
[tex]distance = 480 \: metres[/tex]
And the velocity is :-
[tex]velocity = \frac{480 \: metres}{160 \: seconds} [/tex]
[tex]velocity = 3 \: m/s[/tex]
Therefore, the ostrich ran at a velocity of 3 m/s .
Which equation does the graph below represent?
A coordinate grid is shown. The x-axis values are from negative 5 to positive 5 in increments of 1 for each grid line, and the y-axis values are from negative 10 to positive 10 in increments of 2 for each grid line. A line is shown passing through the ordered pairs negative 4, 8 and 0, 0 and 4, negative 8.
y = −2x
y = fraction negative 1 over 2x
y = 2x
y = fraction 1 over 2x
Answer:
y = -2
Step-by-step explanation:
The graph passes through (0,0) and (-1,2).
The equation of a line passing through the origin is of the form,
y = mx
We now substitute (-1,2) to obtain,
2 = -m
This implies that,
m = -2
The equation is
y = -2

find the values of p and q
If the ordered pairs (p, -1) and (5, q) belong to {(x, y): y = 2x-3}, find the values of p and q.
Solution -Given -
the ordered pairs (p, -1) and (5, q) belong to{(x, y): y = 2x-3)}
To find -
the values of p and qSolution -
{(x, y): y = 2x - 3}
Putting,
x = p and y = -1
[tex]\:\:\:\:\:\implies\:\:[/tex] {(p, -1): - 1 = 2p - 3}
[tex]\:\:\:\:\:\implies\:\:[/tex] -1 + 3 = 2p
[tex]\:\:\:\:\:\implies\:\:[/tex] {2 = 2p}
[tex]\:\:\:\:\:\implies{\tt{\:\:p=\frac{\cancel{2}}{\cancel{2}}}}[/tex]
[tex]\:\:\:\:\:\implies{\boxed{\tt{\:\:p=1}}}[/tex]
{(x, y): y = 2x -3}
Putting,
x = 5 and y = q
[tex]\:\:\:\:\:\implies\:\:[/tex] {(5, q): q = 2(5) - 3}
[tex]\:\:\:\:\:\implies\:\:[/tex] q = 10 - 3

The diagram below, not drawn to scale, shows a prism of length 30 cm. The . cross-section WXYZ is a square with area 144 cm”.
Calculate (i) the volume, in cm', of the prism ( 2 marks) (ii) the total surface area, in cm', of the prism. ( 4 marks)
Answer: 1) 4320 cm^3
2) 1728 cm^2
Step-by-step explanation:
1) V= 12 x 12 x 30 = 4320
2) S= 144 + 144 + 12 x 30 x 4 = 1728
Classify the system of equations and identify the number of solutions.
2x + y = 5
6x + 3y = 25

consistent, dependent; one
consistent, dependent; infinite
inconsistent; none
HELP ASSAP PLS
Step-by-step explanation:
2x + y = 5 (times 3)
6x + 3y = 25
↓↓↓↓↓↓↓↓↓↓↓↓
6x + 3y = 15
6x + 3y = 25
→ No solution ←
2x+y=5
y=-2x+53y=-6x+15--(1)6x+3y=25
3y=-6x+25As slopes are equal lines are parallel
So no solutions

Write 360 as a product of primes.
Use index notation when giving your answer
Answer:
First, find any number that divides evenly into 360. Perhaps the number that comes to mind, since it ends in a 0, is 10. Since 10 divides into 360 and the result is 36, you can write 360 = 10*36.

Find the missing angle
Answer:
58 degree
Step-by-step explanation:
the total degree of the three interior angles together of a triangle = 180
here 2 sides are given so to find the 3rd angle we can just add the other 2 angles and subtract it from 180
so it'll be
[tex]65 + 57 = 122[/tex]
[tex]180 - 122 = 58 \: degrees[/tex]
answer = 58 degree
1) make q the subject of the formula 4(q+p)=5+7q
2) Make x the subject of the formula y=2a-bx^2
Answer:
1) [tex]q = \frac{4p}{3} -\frac{5}{3}[/tex]
2) [tex]x = \frac{\sqrt{b -y + 2a} }{b}[/tex]
Step-by-step explanation:
1) 4(q + p) = 5 + 7q
Multiply 4(q + p):
4q + 4p = 5 + 7q
4p - 5 = 7q - 4q
4p - 5 = 3q
[tex]\frac{4p}{3} - \frac{5}{3} = \frac{3q}{3}[/tex]
[tex]\frac{4p}{3} - \frac{5}{3} = q[/tex] or [tex]q = \frac{4p}{3} - \frac{5}{3}[/tex]
