Answer:
[tex]Sum = 5x[/tex]
Step-by-step explanation:
Given
1: 5x + 20
2: Opposite of 20
Required
Find their sum
Suppose that a is a number; The opposite of a is -a. So, the opposite of 20 is -20.
Having said that:
The required sum is:
[tex]Sum = 5x + 20 + (-20)[/tex]
Remove bracket
[tex]Sum = 5x + 20 -20[/tex]
[tex]Sum = 5x[/tex]

4) The length of a rectangle is 7 inches more than the width. The perimeter of the rectangle
is 178 inches. Find the width of the rectangle.
Answer:
41 inches
please mark brainliest
Step-by-step explanation:
l= 7+w
perimeter = 2(l+w) =2(7+w +w)= 2(7+2w)= 14+ 4w
178= 14+4w
4w =178-14= 164
w= 164/4 = 41 inches

The function g(t) = - 16t2 + vt + h represents the height of an object, g, in feet, above the ground in relation to the time, t, in seconds, since the object was thrown into the air with an initial velocity of v feet per second at an initial height of h feet.
A model rocket is launched off the ground at an initial velocity of 80 feet per second.
Part A: Write a function that can be used to describe the flight of the model rocket.
Answer:
g(t)= -16t^2 +80t
Step-by-step explanation:Should be
A function is a relationship between inputs where each input is related to exactly one output.
The function that can be used to describe the flight of the model rocket is
g(t) = -16t² + 80t.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example: f(x) = 3x + 1 is a function
x = 1, f(1) = 3 + 1 = 4
We have,
A function that represents the height of an object.
g(t) = -16t² + vt + h
t = time in second
v = Initial velocity per second
h = Initial height
Initial velocity:
v = 80 feet per second
A model rocket is launched off the ground.
This means,
h = 0
Now,
Putting v = 80 and h = 0
g(t) = -16t² + vt + h
g(t) = -16t² + 80t + 0
g(t) = -16t² + 80t
Thus,
The function that can be used to describe the flight of the model rocket is
g(t) = -16t² + 80t.

What is the equation of a line, in general form, that passes through point (1,-2) and has a siope of 1/3?
9514 1404 393
Answer:
x -3y -7 = 0
Step-by-step explanation:
The general form of the equation for a line is ...
ax +by +c = 0
where a, b, c are mutually prime and the leading coefficient is greater than zero.
__
The general form equation for a line with slope m = rise/run through point (h, k) can be found by simplifying ...
rise(x -h) -run(y -k) = 0 . . . . where run has the sign of the slope
For the given point and slope, we have ...
1(x -1) -3(y -(-2)) = 0
x -3y -7 = 0
Jana paid an initial fee of $75 to join a fitness gym. She pays $15 per month for her membership. How many months did she have the membership if she spent a total of $255.
asap ill give brainlyist
Answer:
12 months
Step-by-step explanation:
Set up a formula; 75 + 15x = 255
Now, solve for x, which is number of months.
subtract 75 from both sides.
15x = 180
divide both sides by 15.
x = 12
x is equal to 12 - she would have had to have the subscription for 12 months to spend 255$.

there are 5 more than twice as many students taking Algebra 1 then taking algebra 2. If there are 44 students taking Algebra 2, what is the least number of students who could be taking Algebra 1? The least number of students is?
Answer:
93
Step-by-step explanation:
Key :
A1 = Algebra 1
A2 = Algebra 2
Alright so basically lets first look at the info they gave us :
We have 5 more than twice as many students taking A1 than we do A2.
We have 44 students taking A2.
And we need to find the least amount of students that could be taking A1.
So we need to take the amount of students taking A2 (44) and double it to find the amount taking A1.
So we can do 44 x 2 = 88 to get this.
But the problem also states there is 5 more then twice the number of students taking A2.
So we have that 88 but now we just need to add 5 to make up for them telling us that in the problem.
So :
88 + 5 = 93
Our final answer and least amount of students taking A1 is 93 students.
Answer:
93 students
Step-by-step explanation:
44 x 2 = 88
88 + 5 = 93

Suppose the following tables present the number of specimens that tested positive for Type A and Type B influenza in a country during a flu season. Type A 38 100 186 199 253 380 595 966 1611 2638 3845 4931 5183 5367 5890 Type B 59 95 116 143 156 225 271 366 495 696 851 1060 1140 1101 1202 Send data to Excel (a) Find the mean and median number of Type A cases. Round the answers to at least one decimal place. (b) Find the mean and median number of Type B cases. Round the answers to at least one decimal place. (c) A public health official says that there are more than twice as many cases of Type A influenza than Type B. Do these data support this claim
Answer:
(a) Mean and Median of type A
[tex]\bar x = 2145.47[/tex]
[tex]Median = 966[/tex]
(b) Mean and Median of type B
[tex]\bar x = 531.73[/tex]
[tex]Median = 366[/tex]
(c) The claim by the public health worker is true.
Step-by-step explanation:
Given
[tex]Type\ A: 38\ 100\ 186\ 199\ 253\ 380\ 595\ 966\ 1611\ 2638\ 3845\ 4931\ 5183\ 5367\ 5890[/tex]
[tex]Type\ B: 59\ 95\ 116\ 143\ 156\ 225\ 271\ 366\ 495\ 696\ 851\ 1060\ 1140\ 1101\ 1202[/tex]
[tex]n = 15[/tex]
Solving (a): The mean and median of A.
Mean is calculated using:
[tex]\bar x = \frac{\sum x}{n}[/tex]
[tex]\bar x = \frac{38 +100 +186 +199+ 253+ 380+ 595+ 966 +1611 +2638 +3845+ 4931+ 5183 +5367 +5890 }{15}[/tex]
[tex]\bar x = \frac{32182}{15}[/tex]
[tex]\bar x = 2145.47[/tex]
The median is calculated using:
[tex]Median = \frac{n+1}{2}th[/tex]
[tex]Median = \frac{15+1}{2}th[/tex]
[tex]Median = \frac{16}{2}th[/tex]
[tex]Median = 8th[/tex]
The 8th item is: 966
So:
[tex]Median = 966[/tex]
Solving (b): The mean and median of B.
Mean is calculated using:
[tex]\bar x = \frac{\sum x}{n}[/tex]
[tex]\bar x = \frac{59 +95 +116+ 143+ 156+ 225+ 271+ 366+ 495 +696+ 851+ 1060+ 1140 +1101+ 1202}{15}[/tex]
[tex]\bar x = \frac{7976}{15}[/tex]
[tex]\bar x = 531.73[/tex]
The median is calculated using:
[tex]Median = \frac{n+1}{2}th[/tex]
[tex]Median = \frac{15+1}{2}th[/tex]
[tex]Median = \frac{16}{2}th[/tex]
[tex]Median = 8th[/tex]
The 8th item is: 366
So:
[tex]Median = 366[/tex]
(c) The claim by the public health worker is true.
To do this, we simply compare the mean value of both types.
For Type A
[tex]\bar x = 2145.47[/tex]
For Type B
[tex]\bar x = 531.73[/tex]
The claim is:
[tex]Type\ A > 2 * Type B[/tex]
[tex]2145.47 > 2 * 531.73[/tex]
[tex]2145.47 > 1063.46[/tex]
Since the inequality is true, then the claim is true

Answer: 1. The right side of the real object is 4 units long.
2. The top side of the scale drawing is 6 units long.
Step-by-step explanation:
2:1
Scale drawing: 6x8
Object: 3x4
Divide the length in the scale drawing by 2--- The right side of the real object is 4 units long.
8/2= 4
Multiply the top side in the real object by 2--- The top side of the scale drawing is 6 units long.
