Answer:
t = 1.15 seconds.
Step-by-step explanation:
The pumpkin is dropped from the height of = 64 feet.
Now we have to find the time taken to reach the pumpkin on ground. Use the below formula to find the time taken.
H = ½ gt^2
H = height
g = 9.8 (always contant )
t = time taken.
Now insert all the values in the formula.
H = ½ gt^2
64 = ½ ×9.8× t^2
(64×2) / 9.8 = t^2
t = 1.15 seconds.
Can you help me with this
Answer:
12 only.
Step-by-step explanation:
When the question is asking for f(0), it is asking for the value of y when x = 0.
We see that there is only 1 intersection at x = 0, and the y value would equal 12.
Therefore, our answer is 12 only.
Answer:
The answer is a.12 only its where the x coordinate stays 0 and the y coordinate decreases or increases

Mario has LaTeX: 2\frac{1}{4}2 1 4 pounds of trail mix. He puts equal amounts of the trail mix into 6 bags for a hike with his friends. If he uses all of the trail mix, how many pounds will be in each bag?
Answer:
0.375 poundsStep-by-step explanation:
Let the amount of trail mix in each bag be x pounds. If Mario has [tex]2\frac{1}{4}[/tex] pounds of trail mix and puts equal amounts of the trail mix into 6 bags for a hike with his friends, the amount of trail mix in each bag can be derives using the expression;
[tex]2\frac{1}{4} = 6 * x[/tex]
solving for x
[tex]\dfrac{9}{4} = 6x\\\\2.25 = 6x\\\\divide\ both \ sides \ by \ 6\\\\\dfrac{2.25}{6} = \dfrac{6x}{6} \\\\x = 0.375\\[/tex]
Hence 0.375 pounds of trail mix will be in each bag

A camping ground began with 240 pounds of food and each day consumed about 12 pounds. After how many days did they have 180 pounds left
Answer:
5 days
Step-by-step explanation:
Set up linear equation; food= 240-12(day) f=240-12d
f(1)=240-12(1)=240-12=228
f(2)=240-12(2)=240-24=216
Now set food to equal 180, solve for days:
180=240-12d
-240 -240
-60=-12d
/-12 /-12
5=d
To check: f(5)=240-12(5)=240-60=180

Eight more than twice a number is eight. Find the number.
Answer:
Step-by-step explanation:
2x + 8 = 8
Subtract 8 from both sides.
2x = 0
Divide both sides by 2.
x = 0
The required number, eight more than twice a number is eight, is 0.
Given that,
To find the number which is eight more than twice a number is eight.
The technique in computation to use and analyze the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
What is arithmetic?In mathematics, it vends on a number of procedures according to the declarations. There are four primary arithmetic operators, addition, subtraction, multiplication, and division,
Let the number be x,
The eight more than twice a number is eight. So,
8 = 2x + 8
2x = 0
x = 0
Thus, the required number, eight more than twice a number is eight, is 0.

2c+7k=t-2 solve for c
Answer:
c = (t - 2 + 7t) / 2
Step-by-step explanation:
We can isolate c, getting 2c = t - 2 + 7t.
Then, we can divide both sides by 2, getting c = (t - 2 + 7t) / 2.
At a sale, dresses were sold for 95% of their original price. If the dresses originally cost $200 each, how much did a dress cost on sale?
Turn the percentage into a decimal.
95% / 100 = 0.95
Multiply.
200 * 0.95 = 190
Subtract.
200 - 190 = $10
Therefore, the dress costs $10 on sale.
Best of Luck!
Answer: The answer is 190.

What is the probability of choosing a number 1 - 10 that is
greater than 5 or even?
Answer:
70%
Step-by-step explanation:
So, first, our set of choices is 10. This means that there are 10 choices.
We want a number that is greater than 5 or even. Thus, let's mark down all of our choices.
Numbers greater than 5 are:
6, 7, 8, 9, and 10.
Even numbers are:
2, 4, 6, 8, 10.
However, we already counted 6, 8, and 10 previously, so we'll ignore that.
All in all, the following numbers will satisfy our requirements:
2, 4, 6, 7, 8, 9, and 10.
This is 7 out of 10 numbers.
Therefore, our probability is:

Sophomore ------62 ---------------38 --------- 100
Junior --------------43 ----------------- 57 ---------- 100
Senior -------------25 -----------------75 ------------ 100

Required
Determine the percentage of off-campus students
From the above table, we have that:
[tex]Off-Campus = 182[/tex]
[tex]Total\ Surveyed = 400[/tex]
The percentage is then calculated as follows;
[tex]\%Off-Campus = \frac{Off-Campus}{Total-Surveyed} * 100\%[/tex]
[tex]\%Off-Campus = \frac{182}{400} * 100\%[/tex]
[tex]\%Off-Campus = 0.455 * 100\%[/tex]
[tex]\%Off-Campus = 45.5\%[/tex]

Answer:
3(3) + 0.75(2) = (3 + 0.75)x
Step-by-step explanation:
The cost per pound of the mixture is the total cost divided by the total weight.
3 lb granola at $3 per lb has a cost of 3(3)
0.75 lb of raisins at $2 per lb has a cost of 0.75(2)
The total cost is 3(3) + 0.75(2)
The mixture has an unknown cost per lb, so we call it x.
When you multiply the cost per lb of the mix by the total weight, you get the total cost.
Total weight of mix: 3 + 0.75
Cost per lb of mix: x
Total cost of mix: (3 + 0.75)x
Above, we know the total cost is 3(3) + 0.75(2)
We set these two amounts equal to get our equation.
3(3) + 0.75(2) = (3 + 0.75)x
Answer: 3(3) + 0.75(2) = (3 + 0.75)x
when will i know when to add or when to subract
Answer:
Look below:
Step-by-step explanation:
adding is when u see 6 + 10. the plus sign ( the cross ) means to add. Subtract is using the minus sign: 6 - 10.
Answer:
You will know when to add or subtract because of keywords and symbols.
Step-by-step explanation:
Most addition and subtraction problems have keywords that tell you what operation to use. For example, so keywords that tell you that you have to add are altogether, sum, together, and a few other words. Some examples of subtraction problems are less than, and a bunch of other words.

Answer:
[tex]\huge\boxed{\sf a = -12 , b = 8}[/tex]
Step-by-step explanation:
Given polynomial is:
[tex]f(x) = ax^3+ b^2 + 3x + 4[/tex]
[tex]\rule[225]{225}{2}[/tex]
First factor is (x-1)
Let x - 1 = 0 => x = 1
Putting this in the above polynomial
[tex]f(1) = a(1)^3 + b(1)^2 + 3(1) + 4[/tex]
Given that it's remainder is 3
[tex]3 = a + b + 3 + 4[/tex]
[tex]3 = a + b + 7[/tex]
Subtracting 7 to both sides
[tex]-4 = a + b\\OR \\[/tex]
a + b = -4 -------------------------- (1)[tex]\rule[225]{225}{2}[/tex]
Second Factor is 2x + 1
Let 2x + 1 = 0 => x = - 1 / 2
Putting in the above polynomial
[tex]f(-\frac{1}{2} ) = a (-\frac{1}{2} )^3 + b (-\frac{1}{2} )^2 + 3 (-\frac{1}{2} ) + 4[/tex]
The remainder is 6
[tex]6 = -\frac{a}{8} + \frac{b}{4} - \frac{3}{2} + 4\\6 - 4 = -\frac{a}{8} + \frac{b}{4} - \frac{3}{2}\\2 = \frac{-a + 2b -12 }{8} \\-a + 2b - 12 = 16\\-a + 2b = 16 + 12\\[/tex]
-a + 2b = 28 --------------------------------(2)[tex]\rule[225]{225}{2}[/tex]
Adding both equations
a + b - a + 2b = -4 + 28
3b = 24
Dividing both sides by 3
b = 8
[tex]\rule[225]{225}{2}[/tex]
Putting b = 8 in Equation (1)
a + 8 = -4
a = - 4 - 8
a = -12

Mary and Jane have $48 to share in the ratio 3:5. How much did each girl 2 points
receive? (SHOW WORKING)
Answer:
Mary- $18
Jane- $30
Step-by-step explanation:
Add the numbers in the ratio together to get 8, and multiply 8 by the variable of x. Divide the total amount of money that both girls earned by 8. You will get x=6. Multiply 6 by 3 to get the amount of money Mary earned, which is 18, and multiply 6 by 5 to get the amount of money Jane earned, which is 30.
x(3+5) = $48
3x + 5x = $48
8x = $48
8x/8 = $48/8
x = $6
3($6):5($6) = $18:$30
Answer:
Mary = $18
Jane = $30
Step-by-step explanation:
The first thing you need to do is find out how much each part is. To do that you need to add each side of the ratio together (3 + 5 = 8). THen you set up an equation showing the 8 parts * x = 48 and solve for x.
8x = 48
x = 6 <-- Value of each part
Now you multiply the 6 by the number on each side of the ratio,
Mary = 3 * 6 = 18
Jane = 5 * 6 = 30
The above is your answer.
