We want to find the total number of integers that are larger than 40 and smaller than 99 that also are multiples of 3.
The answer is 18.
We can solve this just by counting.
The first multiple of 3 larger than 40 is:
3*14 = 42
Now we know that 99 is also a multiple of 3 and that the multiples of 3 are separated by a distance of 3 units, then the total number of multiples of 3 between 42 and 99 is given by:
(99 - 42)/3 = 19
But we need to remove 1, because we used 99 and we have the restriction that our numbers must be "smaller" than 99.
Then we have a total of 18 multiples of 3 between 40 and 99.

(b) The perimeter of a rectangular window is 240 cm. If the width of the window is 51 cm, what is its length?
Answer:
a) Width: 68 m
b) length: 69 cm
Step-by-step explanation:
A = length x width
6256/92 = 68
(2 x width) + (2 x length) perimeter
240 - 102 = 138

Let's solve your equation step-by-step.
4x+3=7x−6
Step 1: Subtract 7x from both sides.
4x+3−7x=7x−6−7x
−3x+3=−6
Step 2: Subtract 3 from both sides.
−3x+3−3=−6−3
−3x=−9
Step 3: Divide both sides by -3.
-3x ÷ -3 = x
-9 ÷ -3 = 3
x = 3

Suppose a parabola has
vertex (5, -3) and also passes through the point (6, 1). Write the equation
of the parabola in vertex form.
Oy = (x – 5)2 -3
Oy = 4(x – 5)2 -3
Oy = 4(x + 5)2 -3
Oy = 4(x – 5)2 + 3
Answer:
I think is The second one
Step-by-step explanation:
Option B is correct, the equation of the parabola in vertex form is y = 4(x - 5)² - 3.
What is Parabola?A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point and from a fixed straight line which is known as the directrix.
We can start by using the vertex form of the equation of a parabola, which is given by:
y = a(x - h)² + k
where (h, k) is the vertex of the parabola and a determines the shape and direction of the opening of the parabola.
We are given that the vertex is (5, -3),
Substitute h = 5 and k = -3:
y = a(x - 5)² - 3
We also know that the parabola passes through the point (6, 1), so we can substitute x = 6 and y = 1:
1 = a(6 - 5)² - 3
1 = a - 3
a = 4
Substituting a = 4 into the equation
y = 4(x - 5)^2 - 3
Hence, the equation of the parabola in vertex form is y = 4(x - 5)² - 3.

4 years ago a pint of milk
cost £1.05 it now costs £1.26.
What is the percentage
increase of the cost of milk
over 4 years?
Given-
Cost of milk 4 years ago = £1.05
To find-
Percentage increase in cost
Solution-
Increase in cost = £ ( 1.26 - 1.05 )
→ £ 0.21
Percentage increase :-
[tex] \frac{0.21}{1.05} \times 100[/tex]
[tex]→ 20[/tex]
Therefore, Percentage increase of the cost of milk over 4 years is 20% .
✍️ By Benjemin ☺️
Rate of change=1.26-1.05=£0.31
Now percentage of change
