Answer:
198
Step-by-step explanation:
t20=a+19d.......1
t40=a+39d.......2
t2=a+d=2.........3
According to ques,
t40-t20=a+39d-(a+19d)=40
or,20d=40
or,d=2
Now ,putting the value of d in equation 3,we get,
a=0
t100=a+99d
=0+99×2
=198

Find the other endpoint of the line segment with the given endpoint and midpoint.
Endpoint: (4,-9)
Midpoint: (10,8)
Answer:
Other Endpoint (x₂,y₂) = (16,25)
Step-by-step explanation:
We are given endpoint = (4,-9) and midpoint(10,8) we need to find the other endpoint of line segment.
Let other endpoint be (x₂,y₂)
The formula used to find other endpoint is using formula of midpoint
[tex]M(x_m,y_m)=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
We have [tex]x_1=4 , y_1= -9 , x_m=10, y_m=8[/tex]
Using formula and finding (x₂,y₂)
[tex]M(x_m,y_m)=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\(10,8)=(\frac{4+x_2}{2},\frac{-9+y_2}{2})\\10=\frac{4+x_2}{2} , 8=\frac{-9+y_2}{2}\\Finding\ x_2\\10*2=4+x_2 \\20=4+x_2\\x_2=20-4, \\x_2=16\\Finding \ y_2\\8*2=-9+y_2\\16=-9+y_2\\y_2=16+9\\y_2=25[/tex]
So, x₂=16 and y₂=25.
So, Other Endpoint (x₂,y₂) = (16,25)
Plssss just help me I have asked this question like 8 time plssssss help
Answer:
$1.50
Step-by-step explanation:
The constant of proportionality will be the cost for 1 ticket. This means you can find it by dividing the amount for 5 tickets.
7.5=5 tickets
divide both sides by 5
1.5= 1 ticket
one ticket costs $1.50, or the constant of proportionality
Answer:
1.50 would be your answer
Step-by-step explanation:
Ride Tickets x $1.50 = Cost

Answer:
The equivalent ratios are:
16:10
8:5
48:30
Step-by-step explanation:
It is given that the ratios are equivalent ratios. So all the ratios will simplify to the same ratio. We can use this to find the ratios.
given ratio is:
16:10
which simplifies to
8:5
We can observe that the second ratio will be same 8:5
Now,
[tex]\frac{8}{5} = \frac{x}{30}\\x = \frac{8}{5} * 30\\x = 48[/tex]
Hence,
The equivalent ratios are:
16:10
8:5
48:30

Write any number and its additive inverse.
Answer: Additive Inverse of 17 = -17
The two addends in an addition equation are interchangeable, which means that the answer to "What is the additive inverse of -17?" or "What is the additive inverse of negative 17?" is 17. Since the additive inverse of 17 is -17, additive inverse is also known as the opposite number.

8. The table below tracks how much money a taxi driver spent on gas each day:
Monday
Tuesday
Wednesday Thursday
Friday
Money spent
on gas
$57.81
$15.42
$12.50

????
If the taxi driver spent an average of $44.15 on gas each day, how much did he spend on Friday?
Answer:
50.90$
Step-by-step explanation:
add Monday through Friday= 169.85
then multiply 44.15 by 5 = 220.75
subtract both 220.75 by 169.85 = 50.90

Calculate the area of this triangle.
14 cm
11 cmi
18 cm
Answer: 99cm^2
Step-by-step explanation:
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]area = \frac{1}{2} \times (height) \times (base) \\ [/tex]
[tex]height = 11 \: \: cm[/tex]
[tex]base = 18 \: \: cm[/tex]
Thus :
[tex]area = \frac{1}{2} \times 11 \times 18 \\ [/tex]
[tex]area = \frac{18}{2} \times 11 \\ [/tex]
[tex]area = \frac{2 \times 9}{2} \times 11 \\ [/tex]
[tex]area = 9 \times 11[/tex]

Step-by-step explanation:
Karla grows vegetables and collected 32 1/2 lbs of produce to give to her friends. She gave her best friend 8 1/4. How much produce, in pounds, does Karla have left, PLEASE NEED HELP ASP
Answer:
24 1/4 lbs
Step-by-step explanation:
She starts off with 32 1/2 lbs.
She then gives 8 1/4 to her friend.
To find how much she has left, we subtract 8 1/4 from 32 1/2.
To make this easier, lets make them both have a common denominator:
32 2/4 - 8 1/4 = 24 1/4
I hope this helped, please mark Brainliest, thank you so much!
4:■ =8 :14 fhjyghjhgj
Answer:
■ = 7
Explanation:
Because there two ratios are proportional as a result of being equal.
To find the missing part of the ratio, cross multiply, and solve for ■ by converting them into their equivilent fractions.
i.e a : b = a/b.
So 4 : ■ becomes 4/■. And 8 : 14 becomes 8/14.
i.e a/b = c/d → b × c = a × d → bc = ad
Now 4/■ = 8/14 → ■ × 8 = 14 × 4 → 8■ = 56.
8■/8 = 56/8
1■ = 7
■ = 7
This method works for a missing part pretty much anywhere.
____________________
This is a little faster for ratios:
To find the value of the unknown part of the ratio,
just find the factor between two corresponding numbers, and apply that to the known number corresponding to the unknown part.
4 : ■ = 8 : 14
Notice that 4 corresponds to 8
So the factor between these is 2.
Since from 8 to 4 is a multiple of 1/2. 8 × 1/2 = 4, and 14 × 1/2 = ■.
Therefore ■ = 14 × 1/2 = 14/2 = 7
find the measures of -5x+32
Answer: What shape is this? A triangle?
Step-by-step explanation:
Assuming that this is a triangle with no 90 degree angles:
-5x + 32 = 180
-32 = -32
---------------------
-5x = 148
----- = -----
-5 = -5
x = -29.6
Assuming that this is a triangle with 90 degree angles:
-5x + 32 = 90
-32 = -32
----------------------
-5x = 58
----- = -----
-5 = -5
x = 11.6
For both of these you would get a decimal so you need to provide an image or more information to your question
