49/7 as a whole number
Answer:
Here i will simplify 49/7 to its simplest form and convert it to a mixed number if necessary.
In the fraction 49/7, 49 is the numerator and 7 is the denominator.
do this by first finding the greatest common factor of 49 and 7, which is 7.
Then, divide both 49 and 7 by the greatest common factor to get the following simplified fraction:
7/1
Therefore, this equation is true:
49/7 = 7/1
If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. In that case, you could convert it into a whole number or mixed number fraction.
7/1 = 7

Carl sees 25 melons at the store. 15 are small and the rest are large. How many melons are large?
Answer: 10 large melons
Step-by-step explanation:
Carl saw 25 melons at a store.
Of these 25, 15 were small and the rest were large.
The number of large melons will have to be the whole total of 25 melons less the number of small melons which is 15:
= 25 total melons - 15 small melons
= 10 large melons
The ratio of Rogers age to his sons is 7:3. If the sum of their ages are 60 how old is Rogers son
Answer:24
Step-by-step explanation:
Sum of their ages is 60 yr. As such
7x + 3x = 60
10x = 60
x = 60 / 10
x = 6
The rationale is 6, therefore
Father's age is 7x = 7 × 6= 42 years
Son's age is 3x = 3 × 6 = 18 years
Difference in their ages
42 - 18 = 24 years

What is the final elevation if a butterfly starts at 20 m and changes negative 16 m
Answer:
4 meters
Step-by-step explanation:
Given that :
Initial elevation of butterfly = 20 meter
Change in elevation from initial height = negative 16 m = - 16 meter
Final elevation can be obtained by taking the sum of initial elevation and the change in elevation
(20 m + (- 16 m))
(20 m - 16 m)
= 4 meters

350 students signed up what percent signed up for the airforce (64)
Answer: 18.29%
Step-by-step explanation:
There are 350 students. Out of these students, 70 signed up for the Army, 64 for the Airforce, 56 for the Navy and 160 for the Marines for a total of 350.
The percentage of students who signed up for the Airforce out of the total can be calculated by:
= number of students (airforce) / total number of students * 100
= 64/350 * 100
= 18.29%

(adapted from Ross, 2.31) Three countries (the Land of Fire, the Land of Wind, and the Land of Earth) each make a 3 person team. Each team consists of three ninjas, each of a different rank: one genin junior ninja, one journeyman ninja, and one elite ninja.
(a) If a ninja is chosen at random from each of the three different countries, what is the probability of selecting a complete team? (A complete team here is a group consisting of three ninjas, each ninja of a different rank).
(b) If a ninja is chosen at random from each of the three different countries, what is the probability that all 3 ninjas selected have the same rank?
Answer:
The answer is "[tex]\frac{2}{9} \ and \ \frac{1}{9}[/tex]"
Step-by-step explanation:
In point a:
The requires 1 genin, 1 chunin , and 1 jonin to shape a complete team but we all recognize that each nation's team is comprised of 1 genin, 1 chunin, and 1 jonin.
They can now pick 1 genin from a certain matter of national with the value:
[tex]\frac{1}{\binom{3}{1}}=\frac{1}{3} .[/tex]
They can pick 1 Chunin form of the matter of national with the value:
[tex]\frac{1}{\binom{3}{1}}=\frac{1}{3} .[/tex]
They have the option to pick 1 join from of the country team with such a probability: [tex]\frac{1}{\binom{3}{1}}=\frac{1}{3}[/tex]
And we can make the country teams: [tex]3! = 6[/tex] different forms. Its chances of choosing a team full in the process described also are:
[tex]6 \times \frac{1}{3}\times \frac{1}{3}\times \frac{1}{3}=\frac{2}{9}.[/tex]
In point b:
In this scenario, one of the 3 professional sides can either choose 3 genins or 3 chunines or 3 joniners. So, that we can form three groups that contain the same ninjas (either 3 genin or 3 chunin or 3 jonin).
Its likelihood that even a specific nation team ninja would be chosen is now: [tex]\frac{1}{\binom{3}{1}}=\frac{1}{3}[/tex]
Its odds of choosing the same rank ninja in such a different country team are: [tex]\frac{1}{\binom{3}{1}}=\frac{1}{3}[/tex]
The likelihood of choosing the same level Ninja from the residual matter of national is: [tex]\frac{1}{\binom{3}{1}}=\frac{1}{3}[/tex] Therefore, all 3 selected ninjas are likely the same grade: [tex]3\times \frac{1}{3}\times \frac{1}{3}\times \frac{1}{3}=\frac{1}{9}[/tex]

A falling object travels a distance given by the formula d=3t+5t2, where d is measured in feet and t is measured in seconds. How many seconds will it take for the object to travel 84 feet?
Answer:
4.52secs
Step-by-step explanation:
Given the height of a falling object expressed as;
d=3t+5t^2
If the object travel 84 feet, we are to find the time t it takes to travel. On substituting;
84 = 3t+5t^2
3t+5t^2 - 84 = 0
t = -5±√25-4(3)(-84)/2(3)
t = -5±√25+1008/6
t = -5±32.14/6
t = -5+32.14/6
t = 27.14/6
t = 4.52 secs
Hence it will take 4.52secs for the object to travel 84feet
True or false. A linear function always has an exponent of one or zero.
Answer:
False
Step-by-step explanation:
The graph of a linear function is a straight line. Graphically, where the line crosses the x -axis, is called a zero, or root. Algebraically, a zero is an x value at which the function of x is equal to 0 . Linear functions can have none, one, or infinitely many zeros.
Answer:
True.
Step-by-step explanation:
A linear function has the exponent of 0 or 1. A function with a degree of 2 would be quadratic and an exponent of 3 would be cubic.

Find angle3 which is 80º
All lines are 180º
which means angle3+ angle4 is 180º
180º - 80º
= 100º
Answer: B. 100°
Step-by-step explanation:
Since triangles contain angles that add up to 180°, angles 3 is 80°. Since Straight Angles are 180°, it means that angle 4 is 180-80, which equals 100°.
A farmer owns a field with an area of 0.037 km2. The farmer buys another field with an area of 9600 m2. What is the total area of the fields he now owns in km2?
Answer:
0.0946km²
Step-by-step explanation
Area of the farmland owned = 0.037km²
Area of farm land bought = 9600m²
Convert m² to km²
1m² = 1e-6 km²
9600m² = 0.000001 * 9600
9600m² = 0.0576km²
Total area on km² = 0.037km²+0.0576km²
Total area on km² = 0.0946km²
Find the solution of the system of equations 3x+3y=6
9x-5y=-24
Answer:
Then the answer to the system is the point (-1, 3)
which corresponds to x = -1 and y = 3
Step-by-step explanation:
Start by dividing the first equation by 3 on both sides, and get:
x + y = 2
now multiply it by 5 in order to be able to eliminate the term in y in the combining of both equations:
5 x + 5 y = 10
+
9 x - 5 y = - 24
___________
14 x + 0 = -14
solve for x by dividing both sides by 14:
x = -14/14 = -1
Use the x = -1 answer in the equation 3 x + 3 y = 6 and solve for y:
-3 + 3 y = 6
add 3 on both sides:
3 y = 9
divide both sides by 3 to isolate y:
y = 3
Then the answer to the system is the point on the plane (-1, 3)
which corresponds to x = -1 and y = 3
