Add using fraction strip. 1/2 + 5/2
Answer:
3
Step-by-step explanation:
First we look at our problem 1/2 + 5/2. We can see our denominator is the same so we can add our numerators. 1/2 + 5/2 equals 6/2 = 3.
Answer:
If you add this fraction in fraction strip instead of equivalent fraction method
Step-by-step explanation:
firstly draw 5 1/2 fraction strip
then draw 12 1/4 fraction strip
we taking 1/4 bcoz 1/4 is multiple of 1/2, under 1/2 there is 2 1/4.
The end product will be 12/4
cancel out it 12/4 by 2 ans = 6/2 still we can cancel so cancel out 6/2 by 2 at the end ans will be 3/1 = 3
if you think it wrong then use the equivalent fraction method to see the answer..
1/2 + 5/2
denominators are same so we will take only one denominator and will directly add the numerators
1 + 5 = 6 so
6/2 cancel it the ans will be 3/1 and it's equal to 3.

f(x) = 2x^2 - x -10
What are the x-intercepts of the graph of f(x)? Show your work
Answer:
[tex](-2,0) \textsf{ and }\left(\dfrac{5}{2},0\right)[/tex]
Step-by-step explanation:
Given quadratic function:
[tex]f(x)=2x^2-x-10[/tex]
The x-intercepts of the graph are the points at which the curve crosses the x-axis, so when f(x) = 0.
To find these points, factor the quadratic equation, set it to zero, then solve for x.
To factor a quadratic in the form [tex]ax^2+bx+c[/tex], find two numbers that multiply to ac and sum to b.
[tex]\implies ac=2 \cdot -10 = -20[/tex]
[tex]\implies b=-1[/tex]
Therefore, the two numbers are -5 and 4.
Rewrite the middle term as the sum of these two numbers:
[tex]\implies 2x^2-5x+4x-10[/tex]
Factor the first two terms and the last two terms separately:
[tex]\implies x(2x-5)+2(2x-5)[/tex]
Factor out the common term (2x - 5):
[tex]\implies (x+2)(2x-5)[/tex]
Set the factored function to zero:
[tex]\implies (x+2)(2x-5)=0[/tex]
Apply the zero-product property:
[tex]\implies (x+2)=0 \implies x=-2[/tex]
[tex]\implies (2x-5)=0 \implies x=\dfrac{5}{2}[/tex]
Therefore, the x-intercepts of the graph are:

The chances of it happening more than once in 4 trials is 13%
How to determine the numberFrom the information given, we have can deduce that;
Probability of 1 trial = 55%
= 55/ 100
Find the ratio
= 0. 55
We are to find the probability of it happening more than once in 4 different trials
If the probability of it happening in one trial is 555 which equals 0. 55
Then the probability of it happening in 1 in 4 trials is given as;
P(1/4 trials) = 1/ 4 × 55%
P(1/4 trials) = 1/ 4 × 0. 55
Put in decimal form
P(1/4 trials) = 0. 25 × 0. 55
P(1/4 trials) = 0. 138
But we have to know the percentage

The number of bars which can be cut for the 1" X 1" and 2" X 2" square bars are; 117 and 29 units respectively.
How many bars can be cut from the pan in each case?The total area of the given pan can be evaluated as follows;
Area = length × width

Enter your answer as a point (a,b)
Vertex:
Please explain how you arrived at that answer.
The vertex form of the equation f(x) = x^2 - 3x, is f(x) = (x - 3/2)^2 - 9/5
How to rewrite the quadratic function?The quadratic function is given as:
f(x) = x^2 - 3x
Differentiate the function
f'(x) = 2x - 3
Set the function to 0
2x - 3 = 0
Add 3 to both sides
2x = 3
Divide by 2
x = 3/2
Set x = 3/2 in f(x) = x^2 - 3x
f(x) = 3/2^2 - 3 * 3/2
Evaluate
f(x) = -9/5
So, we have:
(x, f(x)) = (3/2, -9/5)
The above represents the vertex of the quadratic function.
This is properly written as:
(h, k) = (3/2, -9/5)
The vertex form of a quadratic function is
f(x) = a(x - h)^2 + k
So, we have:
f(x) = a(x - 3/2)^2 - 9/5
In f(x) = x^2 - 3x,
a = 1
So, we have:
f(x) = (x - 3/2)^2 - 9/5
Hence, the vertex form of the equation f(x) = x^2 - 3x, is f(x) = (x - 3/2)^2 - 9/5

polygon h is a scaled factor of polygon g using a scale factor of 1/4
The fraction of the area of polygon H of polygon G's area would be: 1/16.
What are Similar Polygons?When a polygon is formed by enlarging or reducing an original polygon by a scale factor, the new polygon formed is similar to the original polygon.
What is a Scale Factor?The scale factor = new dimension/original dimension
Given that polygon H is the new polygon formed when polygon G is reduced by a scale factor of 1/4, thus, we would have the following:
Area of polygon H/Area of polygon G = square of the side of polygon H/square of the side of polygon G = square of the scale factor of dilation
Area of polygon H/Area of polygon G = 1²/4² = 1/16
This implies that the area of polygon G is 16 units² while the area of polygon H is 1 units².
