Answer:
9 cups of batter
Step-by-step explanation:
laquisha uses two cups of milk for every three cups of pancake batter to make about 20 pancakes. Which ratio could she solve to find the number of cups of pancake batter, x ,needed if she uses 6 cups of milk
The ratio is given as:
2 cups of milk = 3 cups of batter
6 cups of milk = x
x = 6 × 3/2
x = 9 cups of batter
Determine the input value for which the statement
f(x) = g(x) is true.
From the graph, the input value is approximately .
f(x) = 3 and g(x) = x – 2
3 = x – 2
5 = x
The x-value at which the two functions’ values are equal is .
Answer:
The x-value at which the two functions' values are equal is 5.
Step-by-step explanation:
Let [tex]f(x) = 3[/tex] and [tex]g(x) = x-2[/tex], if [tex]f(x) = g(x)[/tex], then:
[tex]x - 2 = 3[/tex]
[tex]x = 3+2[/tex]
[tex]x = 5[/tex]
The x-value at which the two functions' values are equal is 5.

2. The new Ferrari can accelerate from rest to 100 km/hr in 5 seconds. What is the average acceleration of the car in m/s2?
3. A car starts from a stoplight and is traveling with a velocity of 10 m/sec east in 20 seconds. What is the acceleration of the car?
4. A ball is rolled at a velocity of 12 m/s. After 36 seconds, it comes to a stop. What is the acceleration of the ball?
Answer:
The answer is below
Step-by-step explanation:
Acceleration is the time rate of change in velocity. Acceleration is given by:
Acceleration = change in velocity / time taken
Acceleration = (final velocity - initial velocity) / time
1) The Ferrari is from rest, hence initial velocity = 0. The final velocity = 100 km/h = [tex]\frac{100\ km*1000\ \frac{m}{km} }{1\ hr*\frac{3600\ s}{1\ hr} } =27.78\ m/s[/tex], time = 5 s
Acceleration = (0 - 27.78) / 5 = 5.56 m/s²
2) The car has initial velocity = 10 m/s. The final velocity = 10 m/s since velocity is constant. time = 20 s
Acceleration = (10 - 10) / 20 = 0 m/s²
3) The ball has initial velocity = 12 m/s. The final velocity = 0 m/s since it stops. time = 36 s
Acceleration = (0 - 12) / 36 = -0.33 m/s²
Which point below would you use with the point (-2,-5) to get a line with a slope of -1?
A. (4,1)
B. (1.4)
C. (-6, 1)
D. (-1,-6)
Answer:
(D): (-1,-6)
Step-by-step explanation:
Given
[tex](x_1,y_1) = (-2,-5)[/tex]
[tex]m = -1[/tex]
Required
Find [tex](x_2,y_2)[/tex]
Slope (m) is calculated using:
[tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]
Substitute values for m, x1 and x2
[tex]-1 = \frac{y_2 -(-5)}{x_2 - (-2)}[/tex]
[tex]-1 = \frac{y_2 +5}{x_2 +2}[/tex]
Cross Multiply:
[tex]-1(x_2 +2) = y_2 +5[/tex]
[tex]-x_2 -2 = y_2 +5[/tex]
Make y the subject
[tex]y_2 = -x_2 - 2 - 5[/tex]
[tex]y_2 = -x_2 - 7[/tex]
Only (D): (-1,-6) satisfy this condition:
Substitute -1 for x2 and -6 for y2.
[tex]-6 = -(-1) - 7[/tex]
[tex]-6 = 1- 7[/tex]
[tex]-6 =- 6[/tex]
Hence:
(D): (-1,-6) is true

C. Lisa walks at an average speed of
6 km/h for 1 hours.
Dan completes the same distance in
of an hour.
Calculate Dan's average speed.
Question:
Lisa walks at an average speed of 6 km/h for 15 hours.
Dan completes the same distance in an hour. Calculate Dan's average speed.
Answer:
[tex]Speed = 90km/hr[/tex]
Step-by-step explanation:
Given
Lisa:
[tex]Speed = 6km/hr[/tex]
[tex]Time = 15\ hr[/tex]
First, we calculate the distance covered by Lisa:
[tex]Distance = Speed * Time[/tex]
[tex]Distance = 6km/hr * 15\ hr[/tex]
[tex]Distance = 90km[/tex]
So, Dan distance can be represented as:
[tex]Distance = 90km[/tex] --- Dan completes the same distance as Lisa
[tex]Time = 1\ hr[/tex] -- Time to complete the distance
Dan's average speed is:
[tex]Speed = \frac{Distance}{Time}[/tex]
[tex]Speed = \frac{90km}{1\ hr}[/tex]
[tex]Speed = 90km/hr[/tex]
Hence, Dan's average speed is 90km/hr
-18=-5x-(-2) what is x?
Answer:
x = 4
Step-by-step explanation:
-18 = -5x-(-2)
i) when there is a '-' sign in front of an expression in parentheses, change the sign of each term in the expression-18 = -5x+2
ii) move -5x to the left-hand side and change its sign5x-18 = 2
iii) move -18 to the right-hand side and change its sign5x = 2+18
iv) add the numbers5x = 20
v) divide both sides of the equation by 5[tex] \frac{5x}{5} = \frac{20}{5} [/tex]
[tex]x = 4[/tex]

Find the slope intercept equation of the line
Answer:
Y=2x-2
Step-by-step explanation:
Slope intercept form is also known as y=mx+b
The slope of a line is rise over run. In this case that would be 2/1 which simplifies to 2
The intercept is where the line crosses the y axis, which is at -2
So your equation would be y=2x-2
A circle is cut in half and removed. What is the approximate area (shaded region) of the remaining portion of the circle in square feet? There is a picture of a circle with a line through the middle showing 12 feet.
12 feet ( A=pie(3.14)r^2)
Options are: A. 60 ft2 B. 120 ft2 C. 225 ft2 D. 450 ft2
Answer:
Step-by-step explanation:
area of a whole circle is pi [tex]r^{2}[/tex]
diameter is 2*r
1/2 * pi * [tex]6^{2}[/tex] will find the area of 1/2 of the circle that has a diameter of 12'

The correct sequence of transformations takes A to its image A' is,
⇒ A translation 1 unit down followed by a reflection in the x-axis.
What is mean by Translation?A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.
We have to given that;
The sequence of transformations takes A to its image A'.
Now, We have;
The coordinate of A are (4, 5)
And, The coordinate of A' are (4, - 4)
Hence, The correct sequence of transformations takes A to its image A' is,
