Do these side lengths form a triangle?
Add the two smaller numbers: 3 + 7 = 10
Since 10 is greater than 9, these three side lengths do form a triangle.
Now we qualify the triangle.
c^2 ? a^2 + b^2
The ? is there because we don';t know yet if it will be =, >, or <.
9^2 ? 3^2 + 7^2
81 ? 9 + 49
81 ? 58
Since 81 is greater than 58, now we know to use >.
81 > 58
Since c^2 is greater than a^ + b^2, the triangle is obtuse.
Answer: Yes these side lengths form a triangle, and the triangle is obtuse.

Step-by-step explanation:
Zack, Jack and Sasha earned £250 altogether delivering leaflets.
Zack delivered 50%.
Jack delivered 30%.
Sasha delivered 20%.
They are each paid according to the number of leaflets they delivered.
How much did each person earn?
Answer:
Zack earned £125, Jack earned £75, and Sasha earned £50
Step-by-step explanation:
Considering the number of leaflets delivered
Zack 50%, Jack 30% and Sasha 20%
Total delivered = 50 + 30 + 20 = 100%
If they earn £250 on the 100% delivery, then each will have as shown below
Zack = (50/100)*250
= 5*25
= £125
Jack = (30/100)*250
= 3*25
= £75
Sasha = (20/100)*250
=2*25
= £50
Answer:
£125, £75 and £50
Step-by-step explanation:
Zack delivered 50%
Therefore, Zack earned
50% of £250
50/100 x £250
0.5 x 250
£125
Zack earned £125
Jack delivered 30%, therefore
Jack earned
30% of £250
0.3 x £250
£75
Jack earned £75
Sasha delivered 20%
Therefore, Sasha earned 20% of £250
20/100 x £250
0.2 x £250
£50
Sasha earned £50
Zack + jack + Sasha = £250
£125 + £75 + £50 = £250

Taro uses a coordinate systemwith units of feet to keep frack of the locations of any objects he finds with his metal detector. One lucky day he found a ring at (5,7) and an old coin at (10,19). How far apart were the ring and coin before taro found them? Round them to the nearest tenth if necessary.
Answer:
The distance between ring and coin is 13 units apart.
Step-by-step explanation:
[tex] \sqrt{ {(x1 - x2)}^{2} + {(y1 - y2)}^{2} } [/tex]
Using this formula, you are able to find the distance between the ring and the old coin :
Let (x1,y1) be (10,19),
Let (x2,y2) be (5,7),
D = √(10-5)²+(19-7)²
= √5²+12²
= √25+144
= √169
= 13 units
Answer: 13 units
Step-by-step explanation:
Let (x1,y1) be (10,19),
Let (x2,y2) be (5,7),
D = √(10-5)²+(19-7)²
= √5²+12²
= √25+144
= √169

How does the sign of a affect the domain and range of ()=?f of , open x close . equals eh , x squared , question mark
Answer:
(See explanation for further details).
Step-by-step explanation:
The sign does not affect the domain, as second-order polynomials are continuous functions. Nonetheless, the sign affect the range of function in the sense that elements can be lesser and equal to zero (a < 0) or greater and equal to zero (a > 0).
The sign of 'a' in the function f(x) = ax2 affects the direction the parabola opens, influencing the range of the function, either [0, ∞) for a positive 'a' or (-∞, 0] for a negative 'a'. The domain, which is always (-∞, ∞), isn't affected by 'a's sign.
Explanation:In mathematics, the function f(x) = ax2 is a quadratic function where 'a' is the coefficient of x2. The sign of 'a' determines whether the parabola opens upward or downward. When 'a' is positive, the parabola opens upward hence making the range of the function [0, ∞) because the lowest point (vertex) is on the x-axis and it extends to positive infinity. If 'a' is negative, the parabola opens downward, and the range becomes (-∞, 0] as the highest point is on the x-axis and it extends to negative infinity.
The domain of f(x) = ax2 does not depend on the 'a' value; it is always all real numbers because x can be any real number regardless of the value of 'a'. Therefore, the domain is always (-∞, ∞).

A barge that is used to transport wheat is the shape of a rectangular prism and is 90 feet long, 35 feet wide, and 12 feet deep. What volume of wheat can the barge hold?
Answer: 37,800
Step-by-step explanation: 35x90x12= 37,800
Final answer:
The barge, which is shaped like a rectangular prism and measures 90 feet in length, 35 feet in width, and 12 feet in depth, can hold up to 37,800 cubic feet of wheat.
Explanation:
To determine the volume of wheat that a rectangular prism-shaped barge can hold, we use the formula for the volume of a rectangular prism: Volume = length × width × height. Given that the barge is 90 feet long, 35 feet wide, and 12 feet deep, we calculate the volume as follows:
Volume = 90 feet × 35 feet × 12 feet
Volume = 37,800 cubic feet
Therefore, the barge can hold up to 37,800 cubic feet of wheat.

an angle measure of 55.45 is converted to DMS notation as
Converting angle measure of 55.45 to DMS notation we get 55 degrees 27 minutes 0 seconds
Step-by-step explanation:
We need to convert angle measure of 55.45 to DMS notation
DMS notation is Degree Minute and seconds
Solving:
We have 55.45, the value before decimal is considered as degrees and values after decimal can be minutes and seconds.
We can write it as 55 and 0.45
So, we have 55 degrees
To find minutes we will multiply 0.45 by 60
0.45*60 = 27 minutes
Since we have no decimal value in minutes so seconds will be 0
So, DMS will be 55 degrees 27 minutes 0 seconds
Hence converting angle measure of 55.45 to DMS notation we get 55 degrees 27 minutes 0 seconds
John has 1 ½ hours of homework each day from Monday through Friday and 2 ¾ hours over the weekend. How much work does John have in a week?
Answer:
10.25 (10 1/4)
Step-by-step explanation:
1 1/2 = 1.5
Monday through Friday = 5 days.
1.5 hours of homework times 5 = 7.5
2 3/4 = 2.75 (his homework over the weekend)
7.5 plus 2.75 = 10.25
John would have 10.25, or 10 1/4 hours in a week.
Final answer:
John has 10.25 hours of homework in a week by calculating his daily homework hours and weekend hours.
Explanation:
To calculate the total amount of homework John has in a week:
John has 1 ½ hours of homework each day from Monday through Friday, totaling 1.5 hours/day x 5 days = 7.5 hours.
John has 2 ¾ hours over the weekend, which is 2.75 hours.
Adding the weekday and weekend hours together, John has a total of 7.5 hours + 2.75 hours = 10.25 hours of homework in a week.

The velvet bag contains 10 gold coins and 7 silver coins. A coin is randomly drawn from the bag and NOT replaced. Then a second coin is randomly drawn. What is the probability that both coins are gold?
Answer:
45/136 or 0.3309
Step-by-step explanation:
Total = 10 + 7 = 17
10/17 × 9/16
= 45/136
Or 0.3308823529
Final answer:
To determine the probability of drawing two gold coins in a row from a velvet bag containing 10 gold coins and 7 silver coins without replacement, we multiply the probability of drawing a gold coin on the first and second draw, which is 45/136.
Explanation:
The question involves calculating the probability of drawing two gold coins in succession from a bag containing 10 gold coins and 7 silver coins, without replacement. First, we calculate the probability of drawing one gold coin on the first draw. With 10 gold coins out of a total of 17 coins, this probability is 10/17. After drawing one gold coin, there are now 9 gold coins left out of 16 total coins. The probability of drawing a second gold coin, given the first was already drawn and not replaced, is 9/16. To find the overall probability of both events happening, we multiply the probabilities of each independent event: (10/17) * (9/16) = 90/272. Simplifying this, we get the final probability as 45/136.

Frannie put 1/3 of her music collection on an mp3 player. While on vacation, she listened to 1 /2 of the music on the player. How much of Frannie's music collection did she listen to while on vacation? Choose the correct values to describe how to solve the problem.
Answer:
the solution to the problem is that Frannie listened to 1/6 of her entire music collection while on vacation.
Step-by-step explanation:
Fraction of the music collection on the MP3 player: 1/3
Fraction of the music on the MP3 player listened to: 1/2
Fraction of the entire music collection listened to: 1/6
Frannie listened to [tex]\(\frac{1}{6}\)[/tex] of her music collection while on vacation.
To solve this problem, we need to calculate the fraction of Frannie's total music collection that she listened to on vacation.
Firstly, Frannie put [tex]\(\frac{1}{3}\)[/tex] of her music collection onto her mp3 player. This means that the music on the mp3 player represents [tex]\(\frac{1}{3}\)[/tex] of the whole collection.
While on vacation, she listened to [tex]\(\frac{1}{2}\)[/tex] of the music on the player. So, she listened to [tex]\(\frac{1}{2}\) of \(\frac{1}{3}\)[/tex] of her total collection.
To find out how much of the entire collection this is, we multiply the two fractions together:
[tex]\[ \frac{1}{2} \times \frac{1}{3} = \frac{1}{6} \][/tex]
This multiplication is justified because she listened to half of a third of her collection, which is the same as saying she listened to a sixth of her collection.
Therefore, Frannie listened to [tex]\(\frac{1}{6}\)[/tex] of her music collection while on vacation."

Nicholas sent a chain letter to his friends, asking them to forward the letter to more friends. Every 121212 weeks, the number of people who receive the email increases by an additional 99\%99%99, percent, and can be modeled by a function, PPP, which depends on the amount of time, ttt (in weeks).
The number of people who receive Nicholas's chain letter can be modeled by an exponential growth function. Every 12 weeks, the number of people who have received the letter can be calculated by the formula P(t) = P0(1 + 0.99)^t, where P0 is the initial number of people, and t is the time in weeks.
Explanation:The number of people who receive Nicholas's chain letter is represented by the function P(t) = P0(1 + r)^t, where P0 is the initial number of people, r is the rate of increase (expressed as a decimal), and t is the time in weeks. In this case, r is equal to 99%, or 0.99. So every 12 weeks, the number of people who have received the letter can be modeled as P(t) = P0(1 + 0.99)^t. This is an example of an exponential growth function, which is often used in real-world scenarios where the rate of something increases rapidly, such as interest in a bank account or population growth.
