Answer:
The acceleration of object is -4 ms⁻²
Step-by-step explanation:
We are given:
Initial Velocity = 65 m/s
Final Velocity = 25 m/s
Time t = 10 seconds
We need to find acceleration.
The formula used to find acceleration is: [tex]Acceleration=\frac{Final\:Velocity-Initial\:Velocity}{Time}[/tex]
Putting value in the formula and finding acceleration:
[tex]Acceleration=\frac{Final\:Velocity-Initial\:Velocity}{Time}\\Acceleration=\frac{25-65}{10}\\Acceleration=\frac{-40}{10}\\Acceleration=-4\:ms^{-2}[/tex]
So, acceleration of object is -4 ms⁻²
9,-81, 729,-6561...
What is the common ratio?
Help which is the correct answer?
Answer:
[tex]r = -9[/tex]
Step-by-step explanation:
Given
[tex]Sequence: 9,-81, 729,-6561...[/tex]
Required
Determine the common ratio
The common ratio r is calculated using:
[tex]r = \frac{T_n}{T_{n-1}}[/tex]
Let [tex]n = 2[/tex]
So, we have:
[tex]r = \frac{T_2}{T_{2-1}}[/tex]
[tex]r = \frac{T_2}{T_1}[/tex]
From the sequence:
[tex]T_2 = -81[/tex]
[tex]T_1=9[/tex]
So, the equation becomes
[tex]r = \frac{-81}{9}[/tex]
[tex]r = -9[/tex]
Write an expression for "h less than 13"
Answer:
13-h is h less than 13. this is how you answer this.
Hey there!
Sometimes “less than” means “>” ( a number smaller than the number that’s being compared to) or “subtraction”
So, therefore your answer should be
[h < 13] or [h - 13]
Good luck on your assignment and enjoy your day!

The volume of a cuboid is 40cm3.
The length is 2cm and the width is 4cm.
Work out the height of the cuboid.
Answer:
The height of the cuboid = 5 cm
Step-by-step explanation:
Explanation:-
Given that the volume of the cuboid = 40 cm³
Given that length of the cuboid (l) = 2 cm
Given that the width of the cuboid (w) = 4 cm
The volume of the cuboid is determined by
[tex]V = length X width X height[/tex]
40 = 2× 4× h
h = 5
The height of the cuboid = 5 cm

Answer:
1.a and 2.b.
Step-by-step explanation: let's say the area=2. if you multiply by 2, it gets bigger. if d<1, it's like dividing by a number, meaning that the area becomes smaller.
Answer:
1. a
2. b
Step-by-step explanation:
1. If d is greater than one (d>1), then that means that the shape will be dilated outward, or expanded because the number is larger than the unit of 1.
2. Multiplying the coordinates by a fraction that is less than one (0<d<1) makes the shape smaller, because fractions are smaller than the unit of 1.

Nasser is following this recipe to make flapjacks.
Nasser uses 0.9 kg of oats.
How many flapjacks is Nasser making?
Recipe: Makes 10 flapjacks
120 g margarine
100 g sugar
150 mL syrup
225 g oats
40 g sultanas
Answer:
40 flapjacks
Step-by-step explanation:
Given the recipe :
Recipe: Makes 10 flapjacks
120 g margarine
100 g sugar
150 mL syrup
225 g oats
40 g sultanas
Given that all other ingredients are kept Constant.
225g of oats produces 10 flapjacks
0.9 kg of oat = 0.9 * 1000 = 900g oat
If :
225 g = 10 flapjacks
900 g = x
Cross multiply :
225x = 900 * 10
225x = 9000
x = 9000 / 225
x = 40
40 flapjacks

bcdae============================================
Explanation:
The general form of a slope intercept equation is y = mx+b
m = slope
b = y intercept
Something like y = (-7/6)x + 1 matches with y = mx+b such that m = -7/6 is the slope and b = 1 is the y intercept. So that's why problem 1 matches with choice b (in column B).
Similar situations apply for problems 2 and 3
-----------
For problem 4, we can see the slope is m = -1, but unfortunately m = -1 isn't listed in column B. However, m = -7/7 is listed. So this is why problem 4 matches with choice a. This leaves problem 5 to match with choice e.
note: 6/7 = 12/14 after multiplying top and bottom by 2.

find the value of v
Answer:
v = 38
Step-by-step explanation:
A parallelogram is a quadrilateral in which both sides are the same. That means that 2v is equal to v + 38, and you can solve this. You would get that 2v = v + 38, which means that v = 38.
