Julio accidentally put in an extra 1/10 cup of sugar.
To calculate the number of extra cups of sugar that Julio put in, we need to find the difference between what the recipe called for (3/10 cups) and what he actually added (4/10 cups).
The difference can be calculated as follows:
Actual amount - Required amount = Extra amount
= 4/10 - 3/10
= 1/10

solve the system of equations y = 2x - 5; y = -2x + 3
Answer:
Solving gives us the result, x = 2, y = -1
Step-by-step explanation:
The system of equations is,
y = 2x-5
y=-2x+3
equating the two equations, we get,
(since y = y)
\(2x-5 = -2x + 3\\4x -5 = 3\\4x = 3+5\\4x=8\\x=8/4\\x=2\)
and then since y = 2x-5
\(y=2(2)-5\\y=-1\)
so, x =2, y = -1
Two runners start a race at the same time and finish in a tie. Prove that at some time during the race they have the same speed. [Hint: Consider f(t) = g(t) - h(t) , where and are the position functions of the two runners.
Let's use v1(t) and v2(t) to represent the speed of the first and second runners, respectively, at time t. The functions v1 and v2 must both be continuous in the time variable t, hence this assumption must be made.
So, their difference, a(t), is similarly a continuous function in the variable t, with the formula a(t) = v1(t)-v2(t).
Now, using the principle of contradiction, one may demonstrate that t1, t2, such that a(t1) is less than or equal to 0 and a(t2) is higher than or equal to 0, exist because the overall average speed of both runners is identical.
Now, we may utilize the continuous function a's Intermediate Value Property to locate a t0 between t1 and t2, where a(to)=0 and the runners are moving at the same speed at this point.

Answer:

Step-by-step explanation:
Find the value of x such that the line containing (1,2) and (5,3) is perpendicular to the line containing (x,4) and (3,0)
The value of x that makes the line containing (1,2) and (5,3) perpendicular to the line containing (x,4) and (3,0) is x = 2.
To determine the value of x such that the line containing (1,2) and (5,3) is perpendicular to the line containing (x,4) and (3,0), we need to find the slope of both lines and apply the concept of perpendicular lines.
The slope of a line can be found using the formula:
slope = (change in y) / (change in x)
For the line containing (1,2) and (5,3), the slope is:
slope1 = (3 - 2) / (5 - 1) = 1 / 4
To find the slope of the line containing (x,4) and (3,0), we use the same formula:
slope2 = (0 - 4) / (3 - x) = -4 / (3 - x)
Perpendicular lines have slopes that are negative reciprocals of each other. In other words, if the slope of one line is m, then the slope of a line perpendicular to it is -1/m.
So, we can set up the equation:
-1 / (1/4) = -4 / (3 - x)
Simplifying this equation:
-4 = -4 / (3 - x)
To remove the fraction, we can multiply both sides by (3 - x):
-4(3 - x) = -4
Expanding and simplifying:
-12 + 4x = -4
Adding 12 to both sides:
4x = 8
Dividing both sides by 4:
x = 2

Find the distance between point P and line L
The distance between point P and line L is 16/9√(13).
To find the distance between point P and line L, we can use the formula for the distance between a point and a line in two-dimensional space. The formula is as follows:
Let P = (x1, y1) be the point and L be the line ax + by + c = 0. Then the distance between P and L is:
|ax1 + by1 + c|/√(a² + b²)
To find a, b, and c for the given line, we need to put it in slope-intercept form y = mx + b by solving for y.
2x - 3y = 12=> 2x - 12 = 3y=> (2/3)x - 4 = y
The slope of the line, m, is the coefficient of x, which is 2/3. Therefore, the line is:
y = (2/3)x - 4The values of a, b, and c are: a = 2/3b = -1c = -4
Now we can substitute the coordinates of P and the values of a, b, and c into the formula for the distance between a point and a line.
Let P = (3, 5).|a(3) + b(5) + c|/√(a² + b²)= |(2/3)(3) - 1(5) - 4|/√[(2/3)² + (-1)²]= |-4/3 - 4|/√(4/9 + 1)= 16/9√(13).

Solve the following quadratic inequality x^2+x-6>0
Answer:
x < -3 or x > 2
Step-by-step explanation:
x² + x - 6 > 0
Convert the inequality to an equation.
x² + x - 6 = 0
Factor using the AC method and get:
(x - 2) (x + 3) = 0
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
x - 2 = 0
x = 2
x + 3 = 0
x = -3
So, the solution is x < -3 or x > 2
What is the next term of the arithmetic sequence 24, 16, 8, 0,
Answer:
-8
Step-by-step explanation:
The term-to-term rule is -8.
16 - 24= -8
8 - 16 = -8
0 - 8 = -8
The arithmetic sequence is a concept of algebra and in given sequence 24, 16, 8, 0 the next term is, -8
What is an arithmetic sequence?In the arithmetic sequence the common difference remains constant between any two consecutive terms. In this sequence we can get the next term by adding one fixed value which is known as a common difference. It is also known as arithmetic progression(AP).
Formula for any \(n^{th}\) term in AP,
T = a + (n-1)d
d = T₂-T₁
Where, a is first term , n is \(n^{th}\) term and d is common difference
Given sequence,
24, 16, 8, 0
a = 24
n = 5
d = 16-24 = -8
T₅ = 24 +( (5-1)×(-8))
T₅ = -8
Hence, \(5^{th}\) term of sequence is -8

consider a stick of length 1. we break it at a point which is chosen randomly and uniformly over its length and keep the piece that contains the left end of the stick. we then repeat the same process on the piece that we were left with. let y be the length of the piece that we are left with after breaking twice. find
The expected length of the piece that we are left with after breaking twice is L/4 and the variance Var(X) is 7L^2/144.
In the given question, consider a stick of length 1.
We break it at a point which is chosen randomly and uniformly over its length and keep the piece that contains the left end of the stick.
We then repeat the same process on the piece that we were left with.
We have to find expected length of the piece that we are left with after breaking twice.
In the same setting as Q7, suppose the length of the piece that we are left with after breaking twice is Y.
We also have to calculate the variance Var(Y).
Following Laws are used in the solution
Law of Iterated Expectations: E[X] = E[ E[X|Y] ]
& Law of total variance: Var(X) = E[Var(X|Y)]+Var(E[X|Y])
Now, Y = Length of the stick after we break it the first time
and X = length of the stick after we break it the second time
As both the distribution is uniformly distributed.
Now, E[Y] = L/2 and Var(Y)= l^2/12
E(x|y)[X|Y=y] = y/2 and Var(x|y)[X|Y=y] = y^2/12
As the expectation of uniform distribution over {a,b} is (b-a)/2 and variance is (b-a)^2/12
Using Law of Iterated Expectations
E[X] = E[ E[X|Y] ]
E[X] = E[ y/2 ]
E[X] = \int_{L}^{0}
E[X] = L/4
Now using Law of Total Variance
Var(X) = E[Var(X|Y)]+Var( E[X|Y] )
Var(X) = E[y^2/12]+Var(y/2)
Var(X) = (1/12)*E[Y^2]+(1/4)*Var(Y)
Var(X) = (1*12)*(Var[Y] + (E[Y])^2) + (1/4)*Var(Y)
Var(X) = (1/12)*(L^2/12+L^2/4) + (1/4)*(L^2/12)
Var(X) = 7L^2/144

Chad casts a shadow that is 14.3 feet long. The straight-line distance from the top of chads head to the end of the shadow creates a 23 degree angle with the ground. How tall is Chad, to the nearest tenth of a foot?
If Chad casts a shadow that is 14.3 ft long and the straight-line distance from the top of chads head to the end of the shadow creates a 23 degree angle with the ground. The length of Chad, to the nearest tenth of a foot is: 6.1 .
LengthNow let determine or find how tall is chad
Tan 23° = opposite / adjacent
Tan 23° = Length/Shadow length
Tan 23° = Length/14.3
Length = 14.3× Tan 23°

If you don't consider how the wood might be cut, or how the tray might be assembled, you can look only at the area requirements.
A tray that is 10.5 inches square will have an area of ...
(10.5 in)^2 = 110.25 in^2
That base will have a perimeter that is 4×10.5 in = 42 in. If the perimeter piece(s) are 2 inches high, the area of the sides of the tray will be ...
(42 in)(2 in) = 84 in^2
Then the total area of wood required for the proposed tray is ...
110.25 in^2 +84 in^2 = 194.25 in^2
__
The area of the wood Stephan has is ...
A = LW = (18 in)(12 in) = 216 in^2 . . . . . . more than required
__
Stephan does have enough wood to make the tray, because he has 216 square inches, which is more than he needs to make the tray, 194.25 square inches.
