Denise is conducting a physics experiment to measure the acceleration of a falling object when it slows down and comes to a stop. She drops a wooden block with a mass of 0.5 kilograms on a sensor on the floor. The sensor measures the force of the impact as 4.9 newtons. What’s the acceleration of the wooden block when it hits the sensor? Use F = ma.
Answers
Answer:
9.8m/s2
Step-by-step explanation:
the mass is 0.5kg
the force is 4.9N
you need to find the acceleration
To find the acceleration, divide the force and mass
4.9N/0.5Kg
the answer is 9.8m/s2
To check, multiply the acceleration to the mass
9.8m/s2*0.5Kg=4.9N

Evan and Carter are making chocolate milk which mixes milk with chocolate syrup. Evan's recipe calls for 5 cups of milk for every 4 teaspoons of chocolate syrup. Carter's recipe needs 3 cups of milk for every 2 teaspoons of chocolate syrup. Whose recipe has the stronger tasting chocolate milk?
Answers
Answer:
Evan's recipe
Step-by-step explanation:
Given that:
Evan's recipe :
5 cups of milk for every 4 teaspoons of chocolate syrup
Carter's recipe:
3 cups of milk for every 2 teaspoons of chocolate syrup.
Recipe with the stronger tasting chocolate milk:
Take the ratio of cups of milk to teaspoons of chocolate syrup:
Evan's :
5 / 4 = 1.25
Carter's :
3 /2 = 1.5
Evan's recipe has the stronger tasting chocolate milk recipe :
5 milk cup = 4 chocolate spoons
Number of chocolate milks for 3 milk cups = x in Evan's recipe
5 = 4
3 = x
5x = 12
x = 12/5
x = 2.4 teaspoons
This is 2.4 spoons compared Carter's recipe which uses 2 spoons for every 3 milk cups
PLEASE HELP, 6TH GRADE MATH a chemist is raising the temperature of a liquid the temperature is now 8.4 degrees celsius and is increasing by 1.6 degrees celsius per minute. How many minutes will it take for the temperature to reach 0 degrees celsius?
Answers
Complete question :
A chemist is raising the temperature of a liquid. The temperature is now --8.4 degrees Celsius and is increasing by 1.6 degrees Celsius per minute. How many minutes will it take it for it to take to get to 0 degrees Celsius
Answer:
5.25 minutes
Step-by-step explanation:
Given that :
Current temperature = - 8.4°C
Rate of change = 1.6°C per minute
For the temperature to be 0°C ; it will take
(Final temperature - current temperature) rate of change
(0°C - (-8.4°C)) / 1.6°C
(0°C + 8.4°C) / 1.6°C
8.4°C / 1.6°C
= 5.25 minutes

how do you graph y= 3x-2
Answers
Answer:
Plug in x values into the equation. Start by making a table with x on one side and y on the other. Then, plug in an x value into the equation. We'll start by plugging in 0. This would give us y=3(0)-2, which simplifies to y=-2. Now we know that when x=0, y=-2, so write these two values in your table. Next, we can do this with more points. Let's plug in 1 for x. This gives us y=3(1)-2, which simplifies to y=1 when x=1. Again, we'll write this in our table. After we have a few pairs of x and y values, then we'll draw these points on the graph.
Step-by-step explanation:
The graph of the given linear equation, y = 3x - 2, can be drawn as shown in the coordinate plane attached below.
How to Graph a Linear Equation?To graph y = 3x - 2, choose x-values, calculate the corresponding y-values by substituting them into the equation, plot the points on a coordinate plane, and draw a straight line.
The slope (3) and y-intercept (-2) can be identified from the equation in slope-intercept form (y = mx + b).
Thus, the graph of the linear equation, y = 3x - 2, is shown below.

Write the slope-intercept form of the equation of the line given the slope and the y-intercept.
Slope = -2, y-intercept = -4
Answers
Answer:
y=-2x-4
Step-by-step explanation:
So remember this y=mx+b
The M is the slope and the B is our y-intercept
So according to the picture it gave you the slope and the Y-intercept
The slope was -2 and the y-intercept was -4
So y=mx+b so subtitute the m to -2 and the b to -4
The equation should be y=-2x-4

(3x+1) ^1/3=4. Pls show me the steps to do it.
Answers
Answer:
x = 21
Step-by-step explanation:
(3x+1) ^1/3=4 means that the 1/3 is an exponent that can be rewritten as a cube root.
You can bring the cube root to the other side of the equation.
1. I chose to bring it to the other side of the equation, making it a cube.
(3x+1) ^1/3 = 4
(3x+1) = 4^3
(3x+1) = 4 * 4 * 4
(3x+1) - 1 = 64 - 1
3x/3 = 63/3

The cafeteria at Local Middle School offers a choice of either a sandwich or soup every Thursday. Of all students who purchased lunch this Thursday, 30 chose a sandwich. If the ratio of students who chose a sandwich to all of those who chose soup was 6:5, how many of the students had soup for lunch?
Answers
Answer:
25 students had soup for lunch
Step-by-step explanation:
Sandwich : soup
Of all students who purchased lunch this Thursday, 30 chose a sandwich
Let x = number of students who choose soup
Sandwich : soup = 30 : x
If the ratio of students who chose a sandwich to all of those who chose soup was 6:5
Sandwich : soup = 6 : 5
how many of the students had soup for lunch?
Equate both ratios
Sandwich : soup
30 : x = 6 : 5
30 / x = 6 / 5
Cross product
30 * 5 = x * 6
150 = 6x
Divide both sides by 6
x = 150 / 6
= 25
x = number of students who choose soup = 25 students
