Jerry has 4 1/2 cup of strawberry he use 3/4 cup of a strawberry to make a breakfast smoothie he wants to use the remaining strawberry to make pancakes if he takes 1 1/4 cup of strawberries to make one pancake how many pancake can he make.
Jerry will able to make 3 pancakes if he has 4 1/2 cup of strawberry from which he make use of 3/4 strawberry to make breakfast smoothie and he need 1 1/4 cup of strawberries to make one pancake.
Total strawberry Jerry has = 4 1/2 cup = 9/2 cups
Strawberry used to make smoothies = 3/4 cup
Remaining strawberries
= 9/2 - 3/4
= (18-3)/4 = 15/4
To make one pancake, Jerry needs = 1 1/4 cup = 5/4 cup
Number of pancakes Jerry can make = 15/4/5/4 = 3 pancakes
Hence, the number of pancakes, Jerry can make is 3

Step-by-step explanation:
Use a quadratic equation to find two real numbers with a sum of 31 and a product of 210?
The quadratic equation whose sum of two real roots is 31 and product is 210 will be [tex]x^{2} -31x+210 = 0[/tex].
According to the question,
We have the following information:
The sum of roots of a quadratic equation = 31
The product of roots of a quadratic equation = 210
We know that the standard form of the quadratic equation is given as follows:
[tex]ax^{2} +bx+c = 0[/tex]
Now, the sum of roots is -b/a and the product of roots is c/a.
So, we have the following expressions:
-b/a = 31
b = -31 and a = 1
c/a = 210
c = 210 and a = 1
So, the equation will be:
[tex]x^{2} -31x+210 = 0[/tex]
Hence, the quadratic equation whose sum of two real roots is 31 and product is 210 will be [tex]x^{2} -31x+210 = 0[/tex].

Find the equation of the parabola with the given x-intercepts and point on the graph. Use y = a(x-p)(x-q).
1. x-int: (-2,0) , (5,0)

Below
Step-by-step explanation:
a(x-p)(x-q) p = -2 q = 5
a ( x- - 2)(x - 5) sub in the values of the point given (3,6) to calculate 'a'
6 = a (3+2)(3-5)
a = -6 /10 = - 3/5
y = -3/5 (x+2)(x-5)
Answer:
[tex]\textsf{Intercept form}: \quad y=-\dfrac{3}{5}(x+2)(x-5)[/tex]

p = -2q = 5Substitute the values of p and q into the formula:
[tex]\implies y=a(x-(-2))(x-5)[/tex]

The pharmacists milkweed concoction didn’t work. It only gave the queen split ends. However, the queen, in a rare kind hearted moment, agreed to let the pharmacist try again. This time he has decided to combine a mixture 50% sorghum with a mixture containing 75% sorghum to create a 10 ounce mixture containing 60% sorghum. How many ounces of the 50% mixture should the pharmacist use?
The ounces of the 50% mixture that the pharmacist should use is 6 ounce.
How to calculate the ounces?From the information, we need two equations to solve this problem.
equation 1:
x + y = 10
equation 2:
.5x + .75y = 10(.6)
set y = 10 - x
.5x + .75(10-x) = 6
.5x + 7.5 - .75x = 6
.5x -.75x = 6 - 7.5
-.25x = -1.5
Divide
x = -1.5/-.25
x = 6
Therefore, 6 ounce of the 50% sorghum are required.

Given the points A(-5,-5) and B(7, 1), find the coordinates of the point P on directed line segment AB that partitions AB in the ratio of 1:5, but not necessary In that order, give two possible coordinates of point P. Graph segment AB and P in the coordinate plane.
The two coordinates on the segment AB due to internal division are (5,0) and (-3,-4).
What is internal division?
When a point P divides the line joining the two points and the potint P lies in between the two coordinates then the division is internal division. If the point lies outside of the given coordinates then the division is known as external division.
The division is internally because point P lies on the line as given in the question.
The formula for the internal division is as follows:
[tex]X=\frac{mx_1+nx_2}{m+n}\\Y=\frac{my_1+ny_2}{m+n}[/tex]
Since points are A(-5,-5) and B(7,1) hence, [tex]x_1=-5,x_2=7,y_1=-5,y_2=1[/tex] and ratio is 1:5 then [tex]m=1,n=5[/tex].
Substute all value to obtain the coordinates.
[tex]X_1=\frac{1(-5)+5(7)}{1+5}\\X_1=5\\Y_1=\frac{1(-5)+5(1)}{1+5}\\Y_1=0[/tex]
Hence, the first cordinate is (5,0).
As given in the question that the ratio in not necessarily in the order of 1:5 so, consider the ratio is 5:1.
Now, m=5 and n=1.
Again substitute all values in to find the new coordinate.
[tex]X_2=\frac{5(-5)+1(7)}{5+1}\\X_2=-3\\Y_2=\frac{5(-5)+1(1)}{5+1}\\Y_2=-4[/tex]
Hence, another coordinate is (-3,-4).
Hence, the two coordinates on the segment AB due to internal division are (5,0) and (-3,-4).

Step-by-step explanation:
To simplify an expression, we can combine like terms. For this expression, there are two pairs of like terms, one-fourth y and five-twelfths y, and the constants negative seventeen and six.
To combine the fractions, we can find the least common denominator, twelve, so we can rewrite the fraction as three-twelfths.
Now combine the like terms to get eight-twelfths y minus eleven, which simplifies to two-thirds y minus eleven.
Does y vary directly with x? If it does, what is an equation for the direct variation?
The variable y varies directly with x and the variation equation is (b) y = -1/2x
How to determine the equation of the variation?The graph represents the given parameter
On the graph, we can see that:
The values of x are divided by -2 to get y
This means that the graph represents a direct variation
Recall that we stated that:
The values of x are divided by -2 to get y
This means that the constant of variation is -1/2
The direct variation equation is represented as:
y = kx
Where k represents the constant of variation i.e. k = -1/2
Substitute the known values in the above equation So, we have the following equation
y = -1/2x
Hence, the equation of variation is y = -1/2x

The amount of chlorine needed to treat a wimming
pool i directly proportional to the volume of the pool
The constant of proportionality for the relationship is 0.002.
We are provided that amount of chlorine needed is directly proportional to the volume of the pool .
So we can formulate the relation as
C = kV ... (1) ( where C = amount of chlorine ,
k = constant of proportionality
V = volume of the pool )
the sample ratio of chlorine to the the volume of pool , we have :
5 : 2500
10 : 5000
15 : 7500
So taking the first sample value and putting it in eqn (1)
we get
5 = k (2500)
therefore,
k = 5/ 2500
k = 0.002
So the constant of proportionality will be 0.002
Similarly if we take the other values also the constant of proportionality will remain the same.

Kenya went to the convenience store to buy some snacks. She spent a total of $12. 00 on soda and candy. The soda cost $3. 00 and each candy bar cost $1. 50. If kenya bought one soda, how many candy bars did kenya buy?.
The number of candy bar that she bought is 6
The total amount that she spend for soda and candy= $12
The cost of one soda = $3
The cost of one candy bar = $1.50
Number of soda that she bought = 1
Consider the number of candy bar that she bought as x
Then the equation will be
3×1 + 1.50 × x = 12
Multiply the terms
3 + 1.50x = 12
Move 3 to right hand side of the equation
1.50x = 12 - 3
