Juma bought a geometry set at sh 2000 and later sold it at sh 2500. find his percentage profit
bought price= 2000
sold price= 2500
to find:the percentage profit
solution:[tex]profit\% = 100 \times \frac{(final - initial)}{initial} [/tex]
[tex]profit\% = 100 \times \frac{(2500 - 2000)}{2000} [/tex]
[tex] = \frac{(2500 - 2000)}{2000} [/tex]
[tex] = \frac{1}{4} [/tex]
[tex] = \frac{1}{4} \times 100\%[/tex]
[tex]profit\% = 25\%[/tex]
therefore, his percentage profit is 25.

Step-by-step explanation:
It's clear that the figure is rhombus (because diagonals make right angle).
Rhombus area formula: (AC×BD)÷2
So if we have area and one diagonal then it's easy to find another diagonal.
S=AC×BD÷2
14.5×BD÷2=58
14.5BD=58×2
14.5BD=116
BD=116÷14.5
BD=8
What is 24% of 234 and it has to be 20 characters long
Answer:
56.16
We need to determine 24% of 234 now and the procedure explaining it as such
Step 1: In the given case Output Value is 234.
Step 2: Let us consider the unknown value as x.
Step 3: Consider the output value of 234 = 100%.
Step 4: In the Same way, x = 24%.
Step 5: On dividing the pair of simple equations we got the equation as under
234 = 100% (1).
x = 24% (2).
(234%)/(x%) = 100/24
Step 6: Reciprocal of both the sides results in the following equation
x%/234% = 24/100
Step 7: Simplifying the above obtained equation further will tell what is 24% of 234
x = 56.16%
Therefore, 24% of 234 is 56.16

Use the distribution property to explain how 30 flowers in a bunch can be counted in groups of 2s and 3s.
The way 30 flowers in a bunch can be counted in groups of 2s and 3s is 2(3(3) + 3(2))
Prime factorization of numbersFrom the question, the interpretation is that we are to write the prime factorization of 30
30 = 2 * 15
30 = 2{3 (3 + 2)}
Expand using the distribution property
30 = 2(3(3) + 3(2))
30 = 2(9 + 6)
Hence the way 30 flowers in a bunch can be counted in groups of 2s and 3s is 2(3(3) + 3(2))

NO LINKS!! Explain your answers (show the support by showing the changes in x and y on your table). If the relationship is linear, inverse, or exponential, write the equation.
#5 and #6
Answer:
Linear relationship: increasing or decreasing one variable will cause a corresponding increase or decrease in the other variable.
Inverse relationship: the value of one variable decreases as the value of the other variable increases.
Exponential relationship: a constant change in the independent variable (x) gives the same proportional change in the dependent variable (y)
Question 5
As the x-value increases (by one unit), the y-value decreases.
Therefore, this is an inverse relationship.
The y-values are calculated by dividing 35 by the x-value.
[tex]\sf y=\dfrac{35}{x}[/tex]
**I believe there is a typing error in the table and that the y-value of x = 3 should be 11.67**
Question 6
As the x-value increases, the y-value increases. The y-value increases by a factor of 5 for each x-value increase of 1 unit.
Therefore, this is an exponential relationship.
[tex]\sf y=5^x[/tex]

If the circumstances of the circle below is 72, what is the length of AB (the minor arc)?
Answer:
12
Step-by-step explanation:
In the given circle circumference of the circle is = 72.

line l passes through two points (-2,1) and (4,3) then find the slope of line l and find y-intercept of the line l ,find x-intercept of the line l and write the equation of the line l and sketch the graph of the line i
The linear equation that passes through the two given points is:
y = (1/3)*x + (5/3)
How to find the linear equation?
A linear equation is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If a line passes through two points (x₁, y₁) and (x₂, y₂), then the slope is equal to:
a = (y₂ - y₁)/(x₂ - x₁).
In this case, we know that the line passes through (-2, 1), and (4, 3).
Then the slope is:
a = (3 - 1)/(4 - (-2)) = 2/6 = 1/3
So the line is something like:
y = (1/3)*x + b
To find the value of b, we use the fact that the line passes through the point (4, 3), then:
3 = (1/3)*4 + b
3 - 4/3 = b
5/3 = b
So the line is:
y = (1/3)*x + 5/3
Finally, the x-intercept of the line is the value of x such that y = 0.
0 = (1/3)*x + 5/3
-5/3/(1/3) = x = -5
The graph of the line can be seen below.

The function below describes the total cost, y, of a hamburger with a toppings on it.
y= 1.90 + 1.40x
What does the slope mean in terms of the context?
O The cost of the hamburger will decrease by $1.90 per topping.
O The cost of the hamburger will increase by $1.90 per topping.
O The cost of the hamburger will increase by $1.40 per topping.
O The cost of the hamburger will decrease by $1.40 per topping.
Answer:
O The cost of the hamburger will increase by $1.40 per topping.
Step-by-step explanation:
y = 1.90 + 1.40x→ $1.90 is the fixed cost of the hamburger→ $1.40 is the price per topping and it will increase as the slope of the function/graph is positive⇒ Option 3Answer:
The cost of the hamburger will increase by $1.40 per topping
Step-by-step explanation:
Given equation:
y = 1.90 + 1.40x
where
y = total cost of hamburgerx = number of toppingsThe slope-intercept form of a linear equation is y = mx + b (where m is the slope and b is the y-intercept).
Rearranging the given equation to this form: y = 1.40x + 1.90
Therefore, 1.40 is the slope and 1.90 is the y-intercept.
The slope is the rate of change. This is the amount by which y will change with respect to changes in x. The slope is positive, so as x increases, y will increase.
Therefore, the cost of the hamburger will increase by $1.40 per topping.

DGH~DEF
Find the value of x.
Answer:
25
Step-by-step explanation:
If ΔDGH ~ ΔDEF , then [tex]\frac{DG}{DE}[/tex] = [tex]\frac{GH}{EF}[/tex]
[tex]\frac{x+3}{2x-1}[/tex] = [tex]\frac{52}{91}[/tex]
After cross-multiplication: 52(2x - 1) = 91(x + 3)
104x - 52 = 91x + 273
13x = 325
x = 25
Answer:
x = 25Step-by-step explanation:
DGH~DEF ⇒ their corresponding sides are proportional
then
[tex]\frac{DG}{DE} =\frac{GH}{EF}[/tex]
then
[tex]\frac{52}{91} =\frac{x+3}{2x-1}[/tex]
then
[tex]\frac{4}{7} =\frac{x+3}{2x-1}[/tex]
then
4(2x-1) = 7(x+3) [cross multiply]
then
8x - 4 = 7x + 21
then
8x - 7x = 21 + 4
then
x = 25
