Answer:
3 miles
Step-by-step explanation:
First, we find the rate at which she drives, that is her speed.
Speed is given as:
speed = distance / time
When Cara drives to work, it takes her 30 minutes to drive 15 miles. Her speed is:
s = 15 / 30 = 0.5 miles per minute.
She drives at the same rate to The Dreamy Donut Shop and it takes her 6 minutes.
From the formula of speed, distance is given as:
distance = speed * time
Therefore, the distance of The Dreamy Donut Shop is:
distance = 0.5 * 6 = 3 miles
The Dreamy Donut Shop is 3 miles away.
Answer:
The answer is 3 miles

During his hike, Milt drank 1 liter of water and 1 liter of sports drink. How many milliliters of liquid did he drink?
Answer:
2000 ml of liquid
Step-by-step explanation:
1l plus 1l will equal 2l.
1 liter consists of 1000 milliliters ("milli" means thousand).
If 1l had 1000ml, 2l will have 2000ml.
So 2000mlnis the answer
determine the range of the function graphed above
Answer: A
Step-by-step explanation:
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain. In plain English, the definition means: The range is the resulting y-values we get after substituting all the possible x-values.
The possible values of y are [-infinity,4], so the answer is A

pleaseeeeee help with math. i’ve gotten no help today. explantion needed!!
Answer:
Exactly two distinct zeros
Step-by-step explanation:
y = 2(x-1) (x + 4)
Plug y = 0
0 = 2(x-1) (x + 4)
0/2 = (x-1) (x + 4)
(x-1) (x + 4) = 0
(x-1) = 0 or (x + 4)= 0
x = 1 or x = - 4
Here, x has two distinct roots, therefore given quadratic relation has Exactly two distinct zeros.

A city's mean minimum daily temperature in February is 22 degrees Upper F. Suppose the standard deviation of the minimum temperature in February is 6 degrees Upper F and that the distribution of minimum temperatures in February is approximately Normal. What percentage of days in February has minimum temperatures below freezing left parenthesis 32 degrees Upper F right parenthesis?
Answer:
Probability that X <32 degrees
[tex]=P(Z<\frac{32-22}{6}) =P(Z<1.67)\\ = 0.9522[/tex]
Convert this into percent by multiplying by 100
95.22% of days in February has minimum temperatures below freezing (32 degrees Upper F )
Step-by-step explanation:
Given that a city's mean minimum daily temperature in February is 22 degrees Upper F, with std deviation 6 degrees.
Let X be the minimum temperature in February
Then X is N(22,6)
To calculate percentage of days in February has minimum temperatures below freezing (32 degrees Upper F )
Probability that X <32 degrees
[tex]=P(Z<\frac{32-22}{6}) =P(Z<1.67)\\ = 0.9522[/tex]
Convert this into percent by multiplying by 100
95.22% of days in February has minimum temperatures below freezing (32 degrees Upper F )

A student is doing a reading assignment. After 37 minutes of reading, she skims the pages ahead and estimates that she still has 55% of the reading to do. According to the girl's estimate, how long is the total reading assignment? Round to the nearest minute.
Answer:
82 minutes.
Step-by-step explanation:
So first calculate the percentage 37 minutes is. It is 45%
Next find how much 1% is.
Divide by 45.
[tex]\frac{37}{45}[/tex]
Multiply by 100 to find how much the whole time is: [tex]\frac{3700}{45}[/tex]
The decimal version is: 82.2222222222...
Which simplifies to 82 minutes.
Answer:
82 mins
Step-by-step explanation:
percentage of pages she has already read
100-55= 45%
45%----------- 37mins
55%------------ x mins
x =( 37× 55)/45
x= 45.22 mins
approximately x=45 mins
The time for reading assignment is 37mins + 45 mins = 82 mins.
A spinner with 5 equal sections labeled 1-5 is spun 50 times. The results are shown in the table. What is the experimental probability of spinning a 1?
Answer:
10
Step-by-step explanation:
Spinner divided to 5 equal parts
It is Numbered from (1 to 5): 1, 2, 3, 4, 5
Theoretical probability of spinning 1 = 1/5
Number of times it is spun = 50
Let Experimental probability of spinning 1 = x
1/5 = x/50
5x = 50
x = 50/5
x = 10
Experimental probability of spinning 1 = 10
Answer:
10

A checkout clerk at a department store is expected to complete 16 transactions every hour. In the past 20 minutes, he completed 6 transactions. Choose True or False for each statement.
Answer:
False
Step-by-step explanation:
A checkout clerk at a department store is expected to complete 16 transactions every hour
I.e 16 transactions in 60 minutes
So if it's 6 transactions, let's check to know if the minutes Tally.
16 = 60
6 = (6*60)16
6 = 22.5 minutes
But in the statement it was 20 minutes, so the answer is false.

will mark brainliest!! solve & simplify the following equation: 2x²-7x=4
Answer:
x= −1 /2 or x=4
Step-by-step explanation:
This is ALGEBRA, equations, factoring and zero property. ok.. let's solve this step-by-step
2x^2−7x=4
Step 1: Subtract 4 from both sides.
2x^2−7x−4 =4 −4
2x^2−7x−4=0
Step 2: Factor left side of equation.
(2x+1)(x−4)=0
Step 3: Set factors equal to 0.
2x+1=0 or x−4=0
x= −1 /2 or x=4
(BTW, there are supposed to be two answers, it's factoring)

Answer:X=15d or just 15
Step-by-step explanation:Since there is an increase in manpower/hours of: [8 x 4] / [6 x 5] = 16/15, therefore, there must be decrease in days by the same pecentage. Or 16 / [16 / 15] =16 x 15/16 =15 days

Find the slope of the line going through the points (0,6) and (-3,9)
Answer:
The slope of the line is 5.
The point slope form of the line is y=5x+6.
Step-by-step explanation:
We can find the slope using this formula: [tex]\frac{y_{2} }{x_{2} } -\frac{y_{1} }{x_{1} }[/tex]
[tex]\frac{6}{0} -\frac{9}{-3} =[/tex]
[tex]\frac{6}{0} -(-\frac{9}{3} )=[/tex]
[tex]\frac{6}{0} +\frac{9}{3} =[/tex]
[tex]\frac{15}{3} =[/tex]
5
The slope of the line is 5.
To find point slope form, we use the equation y=mx+b where m is the slope and b is the y-intercept.
The y-intercept of this slope is 6 and the slope is 5 so we get, y=5x+6
What is the value of x in the equation 8x - 2y = 48, when y = 4?
Answer:
x = 7
Step-by-step explanation:
8x - 2y = 48
Let y=4
8x - 2(4) = 48
8x -8 = 48
Add 8 to each side
8x -8+8 = 48+8
8x = 56
8x/8 = 56/8
x = 7
A basketball player's "hang time" is the amount of time the player remains suspended in the air after a jump. The height (in meters) of superstar Michael Jordan during a jump is shown in the graph below. Assume that hhh is the distance from the ground to the lowest part of his body at ttt seconds.. Complete the following sentences based on the graph of the function. Round your answers to the nearest tenth. This is the graph of a function. Michael Jordan's hang time is second(s). The maximum height is about meter(s) . For ttt between t=0.5t=0.5t, equals, 0, point, 5 and t=1t=1t, equals, 1, the height is .
Answer:
The graph is a nonlinear function. Michael Jordan's hang time is 0.9 seconds. The maximum height is about 1 meter. For t between t = 0.5 and t = 1, the height is decreasing.
Step-by-step explanation:
Okay the first one: It's nonlinear because its not a line, its a curve and its definitely not constant. The curve on the graph stops at (0.9,0) so his hangtime is 0.9 seconds. The peak of the curve is about 1 meter. Pretty self explanatory. And the last one, after the point 0.5, the height of the curve goes down, so it is decreasing.
Answer:
The graph is a nonlinear function
Michael Jordan's hang time is 0.9 seconds
The maximum height is about 1 meter
For t between t = 0.5 and t = 1, the height is decreasing.
