Answer:
All the options are equivalent except;
4 + y
Step-by-step explanation:
The question relates to the number of ways the operation of a multiplication operation can be represented algebra
1) The coefficient of a variable is a multiplier of the variable
Therefore;
4y = 4 × y
2) When given two numbers or variables in a mathematical expression that are separated by parenthesis, then it is an indication that the two numbers are meant to be multiplied
Therefore;
(4)(y) = 4 × y
3) The dot symbol, '·', placed between two numbers, a number and a variable or two variables, is a representation of multiplication of the two quantities
Therefore;
4·y = 4 × y
However, multiplication, and addition are different mathematical operations that produce different results when applied;
Therefore;
4 + y ≠ 4 × y.

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!

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.

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.

Answer:
Tn = 8n - 2
Step-by-step explanation:
Given the arithmetic sequence
6, 14, 22, 30, 38
The nth term is expressed as;
Tn = a +(n-1)d
a is the first term = 6
d is the common difference = 14 - 6 = 22 - 14 = 8
Substitute into the formula;
Tn = 6 + (n-1)(8)
Tn = 6 + 8n-8
Tn = 8n - 2
Hence the nth term of the sequence is 8n-2

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
You have two identical boxes which an interior dimensions of 8.0x8.0x8.0. You completely fill one of the boxes with wooden spheres that are 1.6 in diameter. The other box gets filled with wooden cubes that are 1.6 cm on each edge. After putting the lid on the filled boxes, you then measure the density of each. Which one is more dense?
Answer: The one filled with wooden cubes.
Step-by-step explanation:
First, the box filled with spheres will have empty space, this is for how spheres are, so independent of the radius of the sphere, we will always have some empty space inside the box.
In the case of the cubes, this does not happen. Furthermore, the dimension of the box are 8cm by 8cm by 8cm, and the cubes have a sidelength of 1.6cm
We know that:
1.6cm*5 = 8cm
Then we can perfectly fill the box with the wooden cubes (such that there is no empty space like in the previous case).
Because this box has no empty space and is filled with the same material as the other box, we can conclude that this box will have a larger mass than the one filled with spheres.
And we know that:
density = mass/volume.
Both boxes have the same volume, but the box with cubes has a larger mass, then the box with cubes will have a larger density.
Someone help me out. I’m stuck on this problem
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.
