T is between points P and B.
PB=35 and TB=12.
What is PT?
A. 17
B. 12
C. 57
D. 23
A line segment is also a line but a line with finite length and fixed endpoints. The length of the line segment PT is 23 units. The correct option is D.
What is a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.
A line segment is also a line but a line with finite length and fixed endpoints.
Given that point T will lie between points P and B. Therefore, Point T is on the line segment PB. Therefore, it can be said Thus, we can write,
PB = PT + TB
As given the length of PB is 35 units, the length of TB is 12 units,
35 units = PT + 12 units
35 units - 12 units = PT
PT = 23 units
Hence, the length of the line segment PT is 23 units.

Re-write this subtraction as an ADDITION of signed numbers. 7 - 11 = ___
Answer:
-4 + 11 = 7
Step-by-step explanation:
Answer: An expression that would be equal to this one using addition would be 7 + (-11). There is also the option of -7 + 11. When you add a negative, it is the equivalent to subtracting, because you are adding a negative value to a positive value.
Two competing gyms each offer childcare while parents work out. Gym A charges $9.00 per hour of childcare. Gym B charges $0.75 per 5 minutes of childcare. Which comparison of the child care cost is accurate?
Answer:
They are both the same.
Step-by-step explanation:
If you are doing for an hour for Gym B you would do .75 cents for ever 5 minutes of that hour.
60 minutes in an hour so
60/5=12
12*0.75=9.00
So both Gyms are the same.

*PLEASE ANSWER , DIFFICULT QUESTION PLEASE* A particular airline offers three free snack options to it's passengers: cookies, chips, and crackers. Along with the snack, passengers are offered two free drink options: soda or water. This is a tree diagram that represents the probability of customers choosing the different snack and drink options. What is the probability of a passenger choosing chips and a soda? a.)25% b.) 33% c.) 50%
The probability that a particular passenger chooses chips and soda as a snack is 0.25 or 25%.
What is probability?In mathematics, probability is considered as the chances a specific situation or event occurs.
For example, you can calculate the probability that it rains tomorrow based on general weather patterns.
For example,
if you throw a die, then the probability of getting 1 is 1/6.
Similarly, the probability of getting all the numbers from 2,3,4,5 and 6, one at a time is 1/6.
How to calculate the probability of two events happenning?
Calculate or identify the probability of each event happening.Multiply the probabilities of the events involved.What is the probability of Z event happnening?Probability that a person choses soda: 0.5Probability that a person choses chips: 0.5Now, let's multiply these probabilities:Now,
Given that:
0.5 x 0.5
= 0.25
= 25% (0.25 x 100)
Hence, the probability of a passenger choosing chips and soda as a snack is 0.25 or 25%.

Nifal earned 9$ for washing two cars .He recived $1 more for the second car.How much was he paid for washing each car?Which two numbers have a sum of 9$?
Answer:
Nifal received $ 4 for washing the first car.
Nifal received $ 5 for washing the second car.
4 and 5 have a sum of 9.
Step-by-step explanation:
The problem can be rewritten as follows: Find the sum of two consecutive entire numbers equal to 9. That is:
[tex]x + y = 9[/tex]
[tex]y = x+1[/tex]
Then, by eliminating y:
[tex]x + (x+1) = 9[/tex]
[tex]2\cdot x + 1 = 9[/tex]
Now, let is clear [tex]x[/tex]:
[tex]2\cdot x = 8[/tex]
[tex]x = 4[/tex]
Nifal received $ 4 for washing the first car.
The earning for the second car is: ([tex]x = 4[/tex])
[tex]y = x +1[/tex]
[tex]y = 4 + 1[/tex]
[tex]y = 5[/tex]
Nifal received $ 5 for washing the second car.
4 and 5 have a sum of 9.

A hiker travels at 4 miles per hour at a heading of S 35° E from a ranger station. After 3
hours how far south and how far east is the hiker from the station?
Answer:
First, let's define our coordinates.
Let's call East as the positive x-axis and North as the positive y-axis.
Now the data that we have is:
Speed = 4 mph
Time = 3 hours.
Then the total distance traveled is:
D = 4mph*3h = 12 miles.
We also know that the angle is S 35° E.
(from east, 35° to south)
So we can write this angle as -35°.
Then if we want to know the component in South and East, we can first think this in polar coordinates
(R, θ)
where R = 12 miles, and θ = -35°
Now with this, we have that:
X = R*cos(θ) = the displacement to the east.
Y = R*sin(θ) = the displacement to the north (then -Y is the displacement to the south).
Then we have:
X = 12mi*cos(-35°) = 9.83mi
Y = 12mi*sin(-35°) = - 6.89 mi.
Then:
The displacement to the East is X = 9.83 miles
The displacement to the South is -Y = 6.89 miles.
The magnitude of southern displacement of the hiker is 6.88 miles.
The magnitude of eastern displacement of the hiker is 9.83 miles.
The given parameters;
Velocity of the hiker, v = 4 mphPosition of the hiker, θ = S 35⁰ ETime of motion, t = 3 hoursThe resultant displacement of the hiker is calculated as follows;
D = vt
D = 4 mph x 3 h
D = 12 miles
The magnitude of southern displacement of the hiker is calculated as follows;
[tex]D_y = D \times sin(\theta)\\\\D_y = 12 \ miles \times sin(35)\\\\D_y = 6.88 \ miles[/tex]
The magnitude of eastern displacement of the hiker is calculated as follows;
[tex]D_x = D \times cos(35)\\\\D_x = 12 \ miles \times cos(35)\\\\D_x = 9.83 \ miles[/tex]

Stacy sent 10 more texts than twice her little sister yesterday together they sent 46 texts how many texts did Tracy send
Answer:
Tracy sent 12 texts
Step-by-step explanation:
hope this helps
Answer:
The answer is 12 texts.
Step-by-step explanation:
Ok, so I'm assuming that Tracy is the little sister.
Stacy's texts: s
Tracy's texts: t
46 = s + t
s = 2t + 10
Substitute 2t + 10 for s in the first equation.
46 = 2t + 10 + t
46 = 3t + 10
-10 -10
36 = 3t
36/3 = 12
Tracy sent 12 texts and Stacy sent 34 texts.

Camden is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 5 points. What would be Camden's test score out of 50 if he got 2 questions wrong? What would be his score if he got x questions wrong
Answer:
Step-by-step explanation:
Score of 2 questions = 2 *5 = 10
He got 2 questions wrong. So, 50 - 10 = 40.
Camden's test score out of 50 = [tex]\frac{40}{50}[/tex]
Score for x questions = x *5 = 5x
Camden's score if he got 'x' questions wrong = 50 - 5x

The reason why "reposition its product" is the correct answer because Kellogg's is trying to reposition their product in order to make sales. Frosted Flakes was a big time thing for kids, due to the fact that advertisements involved children since Kellogg's target audience were children. Frosted Flakes were pretty much meant for children. Since the product was meant for children, Kellogg's left the people that actually buy the cereal--adults--out of the scene.
Kellogg's releasing advertisements of adults saying how much they loved Frosted Flakes allows viewers to have a thought of going to the store and getting some Frosted Flakes. With the advertisement, they're also trying to target adults because there are a lot of adults in this world, and if they can get adults to buy their product, then their sales will go big. Their goal for the advertisement is to get more sales for the Frosted Flakes product, and they're doing this by having a target audience of adults.

At a butcher shop, Hilda bought 6 9/20 lb of beef and some pork. She left with 17 17/25 lb of meat. Express the number of pounds of pork she bought using a decimal.
Answer:
56.15
Step-by-step explanation:
First, convert [tex]6\frac{9}{20}[/tex] lbs to a decimal. Multiply the main number (6) by the denominator (20) and then add that number to the numerator (9). The number you will get will be (6 x 20)+9 = 129. 129 is now the new numerator as an improper fraction so the improper fraction is now [tex]\frac{129}{20}[/tex].
Now make [tex]17\frac{17}{25}[/tex] lbs an improper fraction. It would be [tex]\frac{442}{25}[/tex].
Now subtract the amount of pork from the total amount of meat. [tex]\frac{442}{25}[/tex] - [tex]\frac{129}{20}[/tex] . Find a common denominator. I'm going to use 500, although there might be something less.
[tex]\frac{5615}{100}[/tex] is the result. Now you can either start dividing or simplify the fraction, which hopefully you already know how to do. 5615 ÷ 100 = 56.15
