Liam is making chocolate chip cookies. The recipe calls for 1 cup of sugar for every 3 cups of flour. Liam only has 2 cups of flour.
How much sugar should Liam use?
Explain why your answer is correct.
Answer:
2/3 cups of sugar
Step-by-step explanation:
Answer:
2/3 cups of sugar
Step-by-step explanation:
If 3 cups of flour: 1 cup of sugar
2 cups of flour: x cup of sugar
Cross multiply
3x = 2 × 1
3 3
x = 2/3
My answer is correct because every 3 cups of flour is a full cup (1) but because he has 2 cups of flour, the cup of sugar is going to be less than 1 because 3 cups of flour is bigger than 2 cups of flour.
The graph for the equation y = x minus 4 is shown below. On a coordinate plane, a line goes through (0, negative 4) and (4, 0). Which equation, when graphed with the given equation, will form a system that has an infinite number of solutions? y minus x = negative 4 y minus x = negative 2
Answer:
The correct option is:
y - x = -4
Step-by-step explanation:
The graphed equation is:
y = x - 4
The equation which will have infinite number of solution should overlap the graphed equation at infinity points.
It is only possible when both the equations are exactly same.
Consider the line given:
y - x = -4
Rearrange the equation:
y = x - 4
Thus, it is the same as the first equation.
Verify for point (0,-4)
y - x = -4
-4 - 0 = -4
-4 = -4
Proved.
Verify for point (4,0)
y - x = -4
0 - 4 = -4
0 = -4+4
0 = 0
Proved
The correct option is (1). [tex]y-x= -4[/tex]
Given equation,
[tex]y = x - 4[/tex]
the line, [tex]y = x - 4[/tex] passes through the points (0, -4) and (4, 0).
Comparing with the general equation of a straight line,
[tex]y = mx + c[/tex] , where [tex]m[/tex] is the slope and [tex]c[/tex] is the y-intercept.
The slope of the equation [tex]y = x - 4[/tex] is 1 and its The y-intercept is -4.
We know that,
Two equations will have an infinite number of solutions when they are on the same line, that is having the same slope and intercept.
Now we check for the slope and the intercept of the given options.
Option (1) [tex]y - x = -4[/tex]
[tex]y = x - 4[/tex]
Here the slope is 1 and y intercept is -4, which is the same as the given equation and both equations will have an infinite number of solutions.
Now option (2).
[tex]y - x = -2[/tex]
[tex]y=x-2[/tex]
The slope is 1 and y intercept is -2
The slope is the same as the given equation but the intercept is different giving no solution.
Hence the correct option is (1). [tex]y-x= -4[/tex]

The low temperature in degrees Fahrenheit for 5 days was – 5, – 7, – 2, 2, and – 3. What was the average low temperature for those days? (Please explain it in detail)
Answer:
-3
Step-by-step explanation:
To find the average of different numbers, first you add them all up. So -5+-7+-2+2+-3+=-15. Then, you divide the sum of all the numbers by the amount of numbers there were. So in this case, there were 5 numbers so we would divide the sum of all of them by 5. So now we do -15/5=-3.
Another example of finding the average of numbers is 15+4+10+9+3+1. So first we add them up and we get 42, then again, we divide by the amount of numbers there are. So we do 40/6 and we get 7, so the average is 7.

Let P(A)=35 and P(B|A)=89. What is the probability of events A and B occurring?
I'm assuming you meant to say P(A) = 3/5 and P(B|A) = 8/9.
If so, then we multiply the probabilities to get P(A and B)
P(A and B) = P(A)*P(B|A)
P(A and B) = (3/5)*(8/9)
P(A and B) = (3*8)/(5*9)
P(A and B) = 8/(5*3)
P(A and B) = 8/15

6x−6=6x+15 Please solve this equation, i'll put the brainliest if its the right answer
Answer:
Step-by-step explanation:
6x-6=6x+15
or, -6+6x=15+6x
adding -6x in both sides
or, -6 + 6x + -6x = 15 + 6x + -6x
Combine like terms: 6x + -6x = 0
or, -6 + 0 = 15 + 6x + -6x
or, -6 = 15 + 6x + -6x
Combine like terms: 6x + -6x = 0
or, -6 = 15 + 0
or, -6 = 15
Solving
-6 = 15

Which of the following equations is of a parabola with a vertex at (0, 6)?
O y= (x - 6)2
O y= (x + 6)2
O y=x2-6
Oy= x2 + 6
Answer:
y= x^2 + 6
Step-by-step explanation:
y= x2 + 6 (which should be written as y= x^2 + 6) has the form y - k = a(x - h)^2. For y= x^2 + 6, h = 0 and k = 6. Thus the vertex is (0, 6)

17x -24+24 = 180 +24
17x = 204
Divide by 17
17x/17 = 204/17
x =12
We want angle CBD
CBD = 9x+17
= 9*12+17
=108+17
= 125

Answer:
3.43
Step-by-step explanation:
To do this you would first find the area of the square which is 16. Then you would find the area of the 2 semicircle or just on whole circle. We are just going to use the formula for a whole circle since there are 2 semicircles. The formula to find a circle is pi times r^2 so we are going to put that into a calculator so we would do pi times 2 (radius of circle)^2 which is 12.57 and we would subtract 16 by 12.57 which is 3.43
Answer:
3.44 units^2
Step-by-step explanation:
Area of a square = l * w
Area of a circle = 3.14 * r^2
Area of semicircle = 3.14 * r^2 * 1/2
Area of shaded region: Area of square - Area of 2 semicircles
Area of square => 4 * 4 = 16
Area of both semicircles => (3.14 * r^2 * 1/2)*2 = 12.56
16 - 12.56 = 3.44
3.44 units^2 is the answer

A rectangle is graphed on the coordinate grid.
Which represents the equation of the side that is parallel to sider?
y=-X+9
y=-x+ 5
y=x-3
y= X+3
Let’s see if I can help you :)!
With two points you can define a line.
So, the line parallel to s is q, which has these two pointS: (3,6) and (6,3)
There are different ways to get the line. For instance, this one:
Y = a*x+b
a = slope = difference_y/difference_x = (3-6)/(6-3) = -1,
y = -x + b,
Now use any point, say (3,6) to get b:
6 = -3+b-> b - 9.
Line is y = -x + 9,
It checks out in the other point: (6,3) —> 3 = -6+9 = 3. Good.
Other method:
y-y2 = a*(x-x2), where (x2,y2) is one of the two points and a is the slope as defined before.
Really hope this helped you!

A person stands 12 meters east of an intersection and watches a car driving away from the intersection to the north at 4 meters per second. At a certain instant, the car is 9 meters from the intersection. What is the rate of change of the distance between the car and the person at that instant (in meters per second)?
Answer: the rate of change of the distance between the car and the person at that instant is 4 meters per second
Step-by-step explanation:
According to the Pythagorean theorem, we have:
d^2 = (12^2 + 9^2)
Differentiating both sides with respect to time:
2d * (dd/dt) = 0 + 2(9) * (9''), Simplifying the equation, we get:
2d * (dd/dt) = 2(9) * (9'')
Substituting the given values:
2d * (dd/dt) = 2(9) * (4) [the car is moving at a constant velocity of 4 m/s]
Simplifying further:
2d * (dd/dt) = 72
we divide both sides by 2d:
dd/dt = 72 / (2d)
substitute this value into the equation to find the rate of change of the distance:
dd/dt = 72 / (2 * 9) = 4 m/s
The rate of change of the distance between the car and the person at that instant is -12/5 meters per second.
Given information:
The person is standing 12 meters east of the intersection.
The car is driving away from the intersection to the north at a constant speed of 4 meters per second.
At a certain instant, the car is 9 meters from the intersection.
Using the Pythagorean theorem, determine D(t) in terms of the car's distance from the intersection, which we'll call x(t).
Since the person is 12 meters east of the intersection, the distance D(t) can be expressed as:
[tex]D(t) = \sqrt{(x(t)^2 + 12^2)[/tex]
Differentiating both sides of the equation with respect to time, we get:
[tex]dD/dt = (1/2) * (x(t)^2 + 12^2)^{(-1/2)} * 2x(t) * dx(t)/dt[/tex]
So, dx(t)/dt = -4
Substituting this value into the equation for dD/dt, we have:
[tex]dD/dt = (1/2) * (x(t)^2 + 12^2)^{(-1/2)} * 2x(t) * (-4)[/tex]
[tex]dD/dt = -4x(t) / \sqrt{(x(t)^2 + 144)[/tex]
At the instant when the car is 9 meters from the intersection, substitute x(t) = 9 into the equation:
[tex]dD/dt = -4(9) / \sqrt{(9^2 + 144)[/tex]
= -36 / √(81 + 144)
= -36 / √225
= -36 / 15
= -12/5
Therefore, the rate of change is -12/5 meters per second.

Answer:
length: 5 yd
width: 4 yd
area: 20 yd^2

1 yd = 3 ft
15 ft * (1 yd)/(3 ft) = 5 yd
12 ft * (1 yd)/(3 ft) = 4 yd
A = LW
A = 5 yd * 4 yd = 20 yd^2
Answer:
20 yd²
Step-by-step explanation:
1 yd = 3 ft =>
=>w = 12ft×yd/3ft = 4 yd
=> l = 15ft×yd/3ft = 5 yd
A = l × w
