Answers
Not certain if this question is complete
Answer and Step-by-step explanation:
We perform the operations given, using the rules of subtraction and addition on the number line:
Two negative signs adds up to a negative result, one negative number and positive number may add up to a negative or positive value depending on which is bigger :
2-26= -24( the positive value 2 reduces negative value by 2 and we are left with -24)
-48-16= -64( two negative values add up to a negative value)
07-6= 1( seven is bigger than 6 hence positive result)
We use the above method to solve the given expressions
+76-200-73= -124-73=-192
-48-16=-64
+7-6-200-73=-199-73=-272
+1-13=-12
-48-16=-64
+07-6=1
+38-200-73=-162-73=-235
1-13=-12
07-6=1
38-73= -35

Two planes travel at a constant speed which plane a travels 2000 and 800 miles in five hours Plan B travels 3885 miles in seven hours which plane is faster
Answers
Answer:
Since its speed is higher, plane 1 is faster than plane 2.
Step-by-step explanation:
Comparing Speeds
The formula for the speed of an object who travels a distance d in a time t is:
[tex]\displaystyle v=\frac{d}{t}[/tex]
We have to compare the speeds of the two planes:
The first plane travels d1=2800 miles in t1=5 hours
The second plane travels d2=3885 miles in t2= 7 hours
Calculate both speeds as follows:
[tex]\displaystyle v_1=\frac{d_1}{t_1}[/tex]
[tex]\displaystyle v_1=\frac{2800}{5}[/tex]
[tex]v_1=560\ mi/h[/tex]
[tex]\displaystyle v_2=\frac{d_2}{t_2}[/tex]
[tex]\displaystyle v_2=\frac{3885}{7}[/tex]
[tex]v_2=555\ mi/h[/tex]
Since its speed is higher, plane 1 is faster than plane 2.

Michael averages 5 three-pointers in his first 4 basketball games. How many does he need to score at his 5th game in order to bring his average to 6 three-pointers per game?
Answers
Answer:
10
Step-by-step explanation:
The easiest way to understand this is not the shortest way.
Give Michael 4 fives and then add an x.
5 + 5 + 5 + 5 + x
Now divide by 5 and equate that to 6
(5 + 5 + 5 + 5 + x)/5 = 6
Combine the left side
(20 + x)/5 = 6
Multiply by 5
(20 + x) = 6*5
20 + x = 30
Subtract 20 from both sides
x = 30 - 20
x = 10
He needs 10 three - pointers to average 6

17 meters

Answers
Answer:
17 meters
Step-by-step explanation:
I did 16^2 and 7^2 to get, 256 + 49 = 305. 305 squared is 17.4... Once you round it you should get the answer 17 meters.
Hope this helps :)
Answer:
The answer is 17 meter
Step-by-step explanation:
So the formula for this is a^2 + b^2 = c^
The two legs are a and b
So plug those into the equation
It should look something like this 7^2 + 16^2 = c^2
Then solve the exponents and you get 49 + 256 = c^2
After that just add the two integers and you have 305
Finally take the square root of 305 and you get 17

Step-by-step explanation:
A projectile is thrown upward so that it's distance above the ground after t seconds is as follows :

We need to find after how many seconds does it reach its maximum height. For maximum height, put [tex]\dfrac{dh}{dt}=0[/tex]
[tex]\dfrac{d(-16t^2+480t)}{dt}=0\\\\-32t+480=0\\\\t=\dfrac{480}{32}\\\\t=15\ s[/tex]

We need to find the sum of the natural numbers between 12 to 38.
To calculate the required sum we have F=12, L=38, but we don't have the value of N.
From 12 to 38 there are 38 - 12 + 1 = 27 natural consecutive numbers, thus N=27.

The domain of a function is the input function that will make the function exist. Based on the function given, the function can exist on all given input value of x. Hence the domain of the function will be;
Domain =(-\infty, infty)
The domain of the function is required.
The domain of the function is the set of real numbers
[tex]x\in(-\infty,\infty)[/tex]
The function is
[tex]f(x)=-16x^2+144[/tex]
The y intercept of the function is
[tex]y=-16\times 0+144\\\Rightarrow y=144[/tex]
[tex](0,144)[/tex]
The y intercept is the maximum height here.
The x intercepts are the points where the object is on the ground.
They are
[tex]0=-16x^2+144\\\Rightarrow 16x^2=144\\\Rightarrow x=\pm\sqrt{\dfrac{144}{16}}\\\Rightarrow x=\pm3[/tex]

Ericka observed the total variation in the water level over 6.2 years to be −13.64 mm. She compared this to the average annual trend, which shows the water level rising 1.8 mm/year. Remember, she used 6.2 years as her time period. What is the difference between how much average water levels rose and how much the water level fell in the part of the river she observed?
Answers
Answer:
3.96mm/year
Step-by-step explanation:
Given that :
Given that:
Observed variation in water level over 6.2 years = - 13.64mm
Average annual trend shows rise in water level at 1.8 mm / year
difference between how much average water levels rose and how much the water level fell in the part of the river she observed?
Average Yearly observed variation :
Observed variation / number of years
-13.64mm / 6.2 years
= - 2.16 mm
Hence, observed yearly fall = - 2.16 mm
Yearly rise = 1.8mm / year
Difference :
( 1.8 mm/year) - (-2.16mm / year)
= (1.8 + 2.16) mm/year

Answers
Answer:
3rd one
Step-by-step explanation:
The correct pattern created by the values is,
⇒ Each value of y is determined by adding 4 to each x - values, so the pattern is additive.
What is Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
We have to given that;
The table shows a relationship between x-and y- values.
Now, We have;
x = 2, 4, 6, 8
y = 6, 8, 10, 12
⇒ 2 + 4 = 6
⇒ 4 + 4 = 8
⇒ 6 + 4 = 10
⇒ 8 + 4 = 12
Clearly, Each value of y is determined by adding 4 to each x - values.
Hence, The pattern is additive.
