The equation computed simply shows that the number of months will be C. 9 months.
How to solve the equationFrom the information given, the equation 8m+3=75 models how many months, m, it takes a tree to reach a height of 75 inches after being potted.
Therefore, the number of months will be calculated thus:
8m + 3 = 75

Answer:
72 stamps
Step-by-step explanation:
First, we're looking to find the number of stamps that AREN'T foreign, so we have to subtract 68% from 100%.
100% - 68% 32%Now, we know that 32% of the stamps are NOT foreign. So, next, we:

the sum of two natural numbers is 28 the product if these numbers is three times the square of the smaller numbers, Find these numbers
Answer:
21 and 7
Step-by-step explanation:
I sort of just used trial and error, but i started with numbers that had a significant difference, like 20, and 8, or 22 and 6
The natural numbers are 7 and 21 if the sum of two natural numbers is 28 the product of these numbers is three times the square of the smaller numbers.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
The sum of two natural numbers is 28 the product of these numbers is three times the square of the smaller numbers
Let x and y be the numbers and x is the smaller number
x + y = 28
xy = 3x²
Plug y = 28 - x in the second equation:
x(28 - x) = 3x²
3x² -28x + x² = 0
4x² -28x = 0
4x(x - 7) = 0
x = 0 or x = 7
y = 28 or y = 21
The natural numbers are 7 and 21
Thus, the natural numbers are 7 and 21 if the sum of two natural numbers is 28 the product of these numbers is three times the square of the smaller numbers.

oh and how do we check the leaderboard
[tex]12s-4s+2=10 \\ 8s = 10 - 2 \\ 8s = 8 \\ \cancel8 s = \cancel8 \\ s = 1[/tex]
Solution:
We know that:
Given equation: 12s - 4s + 2 = 10Step-1: Combine like terms
12s - 4s + 2 = 10s(12 - 4) + 2 = 10s(8) + 2 = 10Step-2: Subtract 2 both sides
s(8) + 2 - 2 = 10 - 2s(8) = 8Step-3: Divide 3 both sides
s(8)/8 = 8/8s = 8/8 = 1Thus, the value of s is 1.
what will be the nature of roots of quadratic equation 2x²+4x-7=0?
Let us consider a quadratic equation αx² + βx + c = 0, then nature of roots of quadratic equation depends upon Discriminant (D) of the quadratic equation.
If Discriminant, D > 0, then roots of the equation are real and unequal.If Discriminant, D = 0, then roots of the equation are real and equal.If Discriminant, D < 0, then roots of the equation are unreal or complex or imaginary.Where,

Given Equation:-[tex]\red{\leadsto}\: \sf{2x^2 + 4x -7= 0} [/tex]
α = 2β = 4c = -7Now,
[tex]\quad\green{ \underline { \boxed{ \sf{Discriminant, D = β² - 4αc}}}} [/tex]
[tex]\begin{gathered}\begin{gathered}\implies\quad \sf D = 4^2-4\times 2\times ( - 7) \end{gathered} \end{gathered} [/tex]
[tex]\begin{gathered}\begin{gathered}\implies\quad \sf D = 16-( - 56)\end{gathered} \end{gathered} [/tex]

Mia has a loyalty card good for a 16% discount at her local grocery store. What would
her total in dollars and cents be, after the discount and before tax, if the total cost of
all the items she wants to buy is $24.50? Round to the nearest cent.
The total price in dollars and cents is twenty dollars and sixty cents.
What are discount rates?Discount rates are the reduction of actual price knowns as a benefit that a customer or a consumer enjoys in the total amount of goods or products being purchased. They are calculated by multiplying the total amount of goods bought with the discount percentage rate given.
From the given information:
Mia's loyalty card has a discount rate of = 16%The total cost of items she wants to buy = $24.50Thus, before tax deduction, the total of items bought while taking the discount rate into consideration is:
= 16% × $24.50
[tex]\mathbf{= \dfrac{16}{100} \times \$24.50}[/tex]

Answer:168.75 squared
Step-by-step explanation: we know that the whole of the rectangle ( including the outline) is 225 cm squared
so half of this is 225 divide by 2 and that is 112.5
but we also have a right-angled triangle that is half the half rectangle so we do 112.5 divide by 2 and that is 56.25
to finish it off we ad 56.25 with 112.5 and that is 168.75
Answer:
180mm²
Step-by-step explanation:
Area of rectangle = 15mm x 9mm

EF = 15mm - 9mm = 6mm
Area of triangle = [tex]\frac{1}{2}[/tex] x 6mm x 15mm

Step-by-step explanation:
The equation of a line that passes through the point (-5,-1) and has a gradient of −1/2. Leave your answer in the form y=mx+c
The number of advance tickets sold was 52.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 8 is an equation.
We have,
Advance tickets x = $5.00
Tickets purchased the night of the concert cost y = $10.50
Total number of tickets = 78
The total cost of the tickets = $533
Now,
x + y = 78
x = 78 - y
Substituting
5x + 10.50y = 533
5 (78 - y) + 10.50y = 533
390 - 5y + 10.50y = 533
5.50y = 533 - 390
5.50y = 143
y = 26
Now,
x = 78 - y
x = 78 - 26
x = 52
Thus,
52 advance tickets were sold.
