how can I do this, can you explain me
Answer:
Step-by-step explanation:
Start with h(t) = -16t^2 + initial height, which here is h(t) = -16t^2 + 1296. Set this = to zero, which corresponds to the object hitting the ground (h = 0):
0 = -16t^2 + 1296. Dividing all terms by -16, we get t^2 = 81, whose positive square root is 9. It takes 9 seconds for the object to hit the ground.

Answer:
y= 6x - 22
Step-by-step explanation:
(4,2) and (5,8)
m= (y2-y1)/(x2-x1)
m= (8-2)/(5-4)
m= 6
y-y1= m(x-x1)
y-2= 6(x-4)
y-2= 6x-24
y= 6x - 22

A party mix is made by adding nuts that sell for $2.50 per kg to a cereal mixture that sells for $1 per kg. How much of each should be added to obtain 40 kg if a mix that will sell for $1.30 per kg?
Answer:
40kg
Step-by-step explanation:
x + y = 60, y = 60 - x
x(2.50) + y(1) = 60(1.50)
Substitute:
2.50 x + 60 - x = 90
1.50x = 30
x = 20 kg
y = 40 kg

If 4x- 7 = 2x, then 2x = ?
If [tex]4x-7=2x[/tex], then [tex]2x=7[/tex].
Hope this helps.
Answer:
7
Step-by-step explanation:
We solve for x first.
So: 4x - 7 = 2x
Subtract 2x from both sides: 4x - 2x - 7 = 2x - 2x
2x - 7 = 0
Add 7 to both sides: 2x - 7 + 7 = 0 + 7
2x = 7
Divide by 2: [tex]\frac{2x}{2}[/tex] = [tex]\frac{7}{2}[/tex]
x = [tex]\frac{7}{2}[/tex]
Now, we substitute x for [tex]\frac{7}{2}[/tex] like this:
2 ( [tex]\frac{7}{2}[/tex]) = 7

2. Charlie has a collection of marbles in three sizes, small, medium, and large. He has four times as
many small marbles as medium marbles. The number of large marbles is three more than five times
the number of medium marbles.
a. Write algebraic expressions to represent the number of small marbles, medium marbles, and
large marbles Charlie has. Write algebrauc expressions to represebt the number of small marbles, medium marbles, and large marbles charlie has.
Answer:
Step-by-step explanation:
The required expression represents the number of the small marbles, medium marbles, and large marbles are m = 4s and l = 3 + 5m.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
Let the number of small marbles be s, medium marbles are m and large marble is l.
According to the question,
He has four times as many small marbles as medium marbles. The number of large marbles is three more than five times the number of medium marbles.
m = 4s
and
l = 3 + 5m
Thus, the required expression represents the number of the small marbles, medium marbles, and large marbles are m = 4s and l = 3 + 5m.

In a bag, there are only black pins, green pins, pink pins and white pins
A pin is taken at random out of the bag
Complete the table
Answer:
P of white: 0.26
P of green: 0.39
Step-by-step explanation:
Assume the probability of a white pin is p.
Then the probability of a green pin is (3/2)p because their ratio is 3:2.
The sum of the probabilities must be 1.
0.1+(3/2)p+0.25+p=1
(5/2)p+0.35=1
(5/2)p=0.65
p=(2/5)(0.65)=0.26
(3/2)p=0.39

Use the Empirical Rule. The mean speed of a sample of vehicles along a stretch of highway is miles per hour, with a standard deviation of miles per hour. Estimate the percent of vehicles whose speeds are between miles per hour and miles per hour. (Assume the data set has a bell-shaped distribution.)
About 68%
Given : The mean speed of a sample of vehicles along a stretch of highway is 66 miles per hour, with a standard deviation of 4 miles per hour.
i.e.
We assume the data set has a bell-shaped distribution (i.e. Normal distribution).
To find : The percent of vehicles whose speeds are between 62 miles per hour and 70 miles per hour.
i.e . The percent of vehicles whose speeds are between miles per hour and miles per hour.
i.e . The percent of vehicles whose speeds are between miles per hour and miles per hour.
i.e. i.e . The percent of vehicles whose speeds are within one standard deviation from the mean.
According to the Empirical rule , about 68% of the population lies within one standard deviation of the mean.
It means , about 68% of vehicles lies within one standard deviation of the mean.
i.e . About 68% of vehicles whose speeds are between miles per hour and miles per hour.
i.e . About 68% of vehicles whose speeds are between miles per hour and miles per hour.
⇒ About 68% of vehicles whose speeds are between 62 miles per hour and 70 miles per hour.

What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
1 minute = 60 seconds
1 hour = 60 minutes
1 km = 1000 m
1 m = 100 cm
We have,
Shed dimensions in the blueprint:
Wide = 7 inches
Length = 3 inches
The scale factor:
34 inch = 3 feet
This means,
Multiply 7/34 on both sides of (1).
7/34 x 34 inch = 7/34 x 3 feet
7 inch = 21/34 feet
7 inch = 0.62 feet _____(A)
Multiply 3/34 on both sides of (1).
3/34 x 34 inches = 3/34 x 3 feet
3 inches = 0.26 feet ______(B)
From (A) and (B) we get,
Wide = 0.62 feet
Length = 0.26 feet
The actual dimension of the shed.
Length = 0.26 feet
Wide = 0.62 feet
Thus,
The dimension of the actual shed.
Length = 0.26 feet
Wide = 0.62 feet
