Number of pounds of dough used = 3/5 pounds.
Number of pounds of sugar used = 3/4 pounds
Number of pounds of sprinkles used = 2/3 pounds.
Total number of pounds of donuts = Number of pounds of dough used + Number of pounds of sugar used + Number of pounds of sprinkles used.
Plugging values.
Total number of pounds of donuts = 3/5 + 3/4 + 2/3.
We need to add all those fractions.
In order to add fracions, we need to find common denominator (lcd).
We have 5,4 and 3 in denominators.
Least common denominator(lcd) of 5, 4 and 3 is 60.
We need to make each denominator equals 60.
Multiplying first fracion by 12 in top and bottom, we get
3*12/5*12 = 36/60
Multiplying first fracion by 5 in top and bottom, we get
3*15/4*15 = 45/60
Multiplying first fracion by 20 in top and bottom, we get
2*20/3*20 = 40/60.
Therefore,
3/5 + 3/4 + 2/3 = 36/60 + 45/60 + 40/60
= 121/60
Let us convert 121/60 into mixed fraction.
Dividing 121 by 60 we get quotient =2 and remainder =1.
So, the mixed fraction is 2 1/60.
Therefore, Beulah made total 2 1/60 pounds of donuts.
The total weight of the donuts can be found by adding together the weights of the dough, sugar, and sprinkles, which comes to approximately 2.02 pounds.
The total weight of the donuts Beulah made can be found by adding the weights of the ingredients - dough, sugar, and sprinkles - together. First, she used 3/5 pounds of dough, to which she added 3/4 pound of sugar. Lastly, she used 2/3 pounds of sprinkles.
Now, let's add these quantities:
Therefore, "Beulah made about 2.02 pounds of donuts".

Answer:
h = 16
Step-by-step explanation:
to solve this equation
we are going to take cognizance of the positive and negative sign as any misinterpretation of the sign might influence our answer wrongly. Note this
negative × negative = positive
positive × negative = negative
negative × positive = negative
positive × positive = positive
so, from the question 19 - h - h = -13
19 - h - h = -13
19 -2h = -13
collect the like terms
19 + 13 = 2h
32 = 2h
divide both sides by the coefficient of h which is 2
32/2 = 2h/2
16 = h
therefore h = 16
Points "in common with the x-axis" are also known as the roots of the quadratic equation . You can apply the quadratic root formula to determine the roots, and also to determine how many such roots there are. With a quadratic (whose graph is a parabola), there can be maximum of 2 roots. But under certain circumstances, there may be only one or no such root.
The root formula for a generic quadratic is as follows:
The expression under the square root is called the determinant. It is called so because it determines the number of real roots. If the determinant value is > 0, there will be 2 roots (and so the parabola will cross the x-axis in 2 points), if its value is =0, there will be only a single root (the the parabola will touch the x-axis in exactly one point), and, finally, if its value is < 0, the quadratic has no real root (andthe parabola will not have any x-intercepts).
So, let's take a look:
This means the parabola will intercept the x-axis at 2 points, two real roots.
Since the coefficient of the quadratic term is positive (a=1), the parabola is oriented "open-up." But since we already know the parabola intercepts in two points, the fact that it is open-up implies now that the vertex must lie below the x-axis (otherwise it could not intercept it).
Answer:
x = 4.4
Step-by-step explanation:
To determine the scale factor, calculate the ratio of corresponding sides, image to original, that is
= ( cross- multiply )
10x = 44 ( divide both sides by 10 )
x = 4.4

x2 + 6x + 6 = 0
Answer:
The solution of x^2 + 6x + 6 is x = -1.2679 or -4.7320
Solution:
A two degree polynomial equation is given in the question.
We have been asked to solve it to find the value of ‘x’.
The given equation is:
There are two ways to solve this equation.
We can either factorise it or use the quadratic equation formula. For factorising it, it has to satisfy certain conditions.
The condition is should be a perfect square otherwise the equation is not factorable.
a=1,b=6,c=6
On substituting the values of a,b and c, we get:
Which is not a perfect square.
Hence we have to use the quadratic equation is
By substituting the values of a,b and in the quadratic equations. We get;
The two roots of x are:
On solving both the equations we will get the roots of the given equation, which are:
x = -1.2679 or -4.7320
Answer:
-1.2679 or -4.7320
