Step-by-step explanation:
Claim: There's 14 Goats and 9 Chickens!!
Data:
Working with the Provided Information.
Let the Number of goats be x
let the Number of Chickens be y
x + y = 23..... (i)
Since the goat Possesses Two Pair of Legs... Which is a Total of 4 Legs... We say Let its Contribution be 4x.
The Chicken has Only a Pair Of Legs...Which is a total of 2 legs.... We say let its contribution be 2y
4x + 2y = 74 .....(ii)
BRINGING BOTH EQUATIONS TOGETHER.
x + y = 23
4x + 2y = 74
From Eqn i
x= 23 - y
Substitute into eqn ii
4(23 - y ) + 2y = 74
92 - 4y + 2y = 74
92 - 2y = 74
2y = 92 - 74
2y = 18
y= 9.
Substitute y into any of the eqns to get x
x + y = 23
x + 9=23
x = 23 - 9
x = 14
This simply proves that there are 14 Goats and 9 Chickens!!!.

Lena and Ras drive to work.
Lena drives 24 miles in 1.5 hours.
Ras drives 36 km in 1 hour 15 min.
Work out the difference between their average speeds in km/h.
1 mile = 1.6 km
km/h
Answer:
3.2 km/h
Step-by-step explanation:
1. Approach
The average speed is the rate at which one travels. It can be found by diving the total distance traveled over the total time it took to cover that distance. In essence, the following formula can be used to find the average speed:
[tex]\frac{total\ distance}{total\ time}=average\ speed[/tex]
In this situation, one is asked to find the difference between two people's average speed. One is given the following information:
Lena: 24 miles 1.5 hours
Ras: 36km 1 hour 15 minutes
First, convert all of the numbers into the correct units (km) and (hours). Then find the average speed for each person. Finally, subtract the smaller speed from the larger speed to find the difference in the average speeds.
1. Find Lena's average speed
The problem asks one to find the average speed in the units (km/h). However, the distance Lena covered is given in (miles). Therefore, one has to multiply it by the conversion factor (1.6) in order to convert it from (miles) to (km).
24miles * 1.6 = 38.4
Now find the average speed by using the formula:
[tex]\frac{total\ distance}{total\ time}=average\ speed[/tex]
Substitute,
[tex]\frac{38.4}{1.5}\\\\=25.6[/tex]
2. Find Ras's average speed
Use a similar approach to work out Ras's average speed, as was used to find Lena's average speed. Since Ras's time spent is given in both hours and minutes, one must convert it to just minutes. There are (60) minutes in an hour, thus, one can rewrite the number as the following:
[tex]1\ hour \ \ 15\ minutes= 1 \frac{15}{60}\ hours = \frac{75}{60}\ hours[/tex]
Now find the average speed:
[tex]\frac{total\ distance}{total\ time}=average\ speed[/tex]
Substitute,
[tex]\frac{36}{\frac{75}{60}}\\\\=28.8[/tex]
3. Find the difference between the speeds
Since Ras's speed is greater, subtract Lena's speed from Ras's speed.
Ras - Lena
= 28.8 - 25.6
= 3.2

Find the known measures. Round lengths to the nearest hundredth and angle measures to the nearest degree.
Answer:
KM = 10.68
K = 55 degrees
M = 35 degrees
Step-by-step explanation:
Firstly, we can use Pythagoras’ theorem to calculate the length of the hypotenuse which is KM
Mathematically, this is the sum of the squares of the two other sides KL and LM according to Pythagoras’ theorem
Thus, we have it that;
KM^2 = KL^2 + LM^2
KM^2 = 6.2^2 + 8.7^2
KM^2 = 114.13
KM = √(114.13)
KM = 10.68
We have two angles to calculate
Let us start with the angle at vertex K
The opposite side to is is the length LM which is 8.7
The adjacent side to it is the length 6.2
Mathematically, the relationship between the two can be calculated using the Tan ; as the Tan of an angle is the ratio of the length of the opposite to that of the adjacent
thus;
Tan K = 8.7/6.2
K = arc Tan (8.7/6.2)
K = 54.5 which is 55 degrees
since we have a right angle , we only have to subtract he measure of angle K from 90 to get the measure of M
M = 90-55 = 35 degrees

3(x + 4) + 2 = 2 + 5(x – 4). Her steps are below:
3x + 12 + 2 = 2 + 5x – 20
3x + 14 = 5x – 18
14 = 2x – 18
32 = 2x
16 = x
Answer:
The answer is correct
Step-by-step explanation:
3(x + 4) + 2 = 2 + 5(x – 4)
3x + 12 + 2 = 2 + 5x - 20
3x + 14 = 5x - 18
-2x = -32

Jane spent 3 hours exploring a mountain with a dirt bike. First, she rode 48 miles uphill. After she reached the peak she rode for 15 miles along the summit. While going uphill, she went 5 mph slower than when she was on the summit. What was her rate along the summit?
Answer: [tex]25\ mph[/tex]
Step-by-step explanation:
Given
Jane took 3 hours
First she rode 48 miles with let say with [tex]x[/tex] mph
then she rode 15 miles with speed [tex](x+5)[/tex] mph
Equate the time in each ride and equate it to total time
[tex]\Rightarrow 3=\dfrac{48}{x}+\dfrac{15}{x+5}\\\\\Rightarrow 3x(x+5)=48(x+5)+15x\\\\\Rightarrow 3x^2+15x=48x+48\times 5+15x\\\\\Rightarrow 3x^2-48x-240=0\\\\\Rightarrow (x-20)(x+4)=0\\\\\text{Neglecting the negative value as speed cannot be negative}\\\\\Rightarrow x=20\ mph[/tex]
So, her along the summit is [tex]x+5=25\ mph[/tex]

Brittany and Natalie, start cycling together from their home to school, which is 14.4 miles away. Natalie takes 40 minutes to reach school and Brittany reaches 20 minutes after Natalie.
How much faster is Natalie (in mph)?
The result shows that Brittany is faster than Natalie because she moved faster than her. Therefore, Brittany is (43.64 - 21.5) = 22.14mph faster than Natalie.
How to calculate average speed?The average speed can be calculated by dividing the distance moved by the time taken. That is;
Average speed = Distance/time
According to this question, Brittany and Natalie start cycling together from their home to school, which is 14.4 miles away.
However, Natalie takes 40 minutes to reach school and Brittany reaches 20 minutes after Natalie.
First, we calculate the average speed of each individual as follows:
Natalie = 14.4miles ÷ 0.67hrs = 21.5mphBrittany = 14.4miles ÷ 0.33hrs = 43.64mphThis shows that Brittany is faster than Natalie because she moved faster than her. Therefore, Brittany is (43.64 - 21.5) = 22.14mph.

Answer:
6 ≈ 27.78C
7 = 219.2F
8 = 20C
9 = 116.6F
Step-by-step explanation:
6. From the formula C/5 = (F-32)/9
We get C/5 = (82-32)/9
C = (50/9)*5
C ≈ 27.78
7. From the formula C/5 = (F-32)/9
We get 104/5 = (F-32)/9
F-32 = 104/5 * 9
F-32 = 187.2
F = 219.2
8. From the formula C/5 = (F-32)/9
We get C/5 = (68-32)/9
C/5 = 36/9
C/5 = 4
C = 5 * 4
C = 20
9. From the formula C/5 = (F-32)/9
We get C/5 = (F-32)/9
47/5 = (F-32)/9
(47/5)*9 = (F-32)
84.6 = F-32
F = 84.6 + 32
F = 116.6

find the measure of the missing side in the right triangle
Answer:
[tex]12.2\text{ ft}[/tex]
Step-by-step explanation:
In any right triangles, the Pythagorean Theorem states that the sum of the squares of both legs is equal to the hypotenuse squared ([tex]a^2+b^2=c^2[/tex], where [tex]c[/tex] is the hypotenuse, or longest side).
In this case, the length we're solving for is the hypotenuse of the triangle and the two legs of the triangle are 7 and 10. Therefore, we have:
[tex]7^2+10^2=c^2,\\49+100=c^2,\\c^2=149,\\c=\sqrt{149},\\c\approx \boxed{12.2\text{ ft}}[/tex]

Answer:
a) (1.75 +1.00d)/4 < (3.50 +1.50d)/5
b) 3.70
Step-by-step explanation:
a) You want ...
classic cost < XL cost
Using the given expressions for the costs, the inequality is ...
(1.75 +1.00d)/4 < (3.50 +1.50d)/5
__
b) For a 10-mile ride, the XL cost is ...
(3.50 +1.50(10))/5 = (3.50 +15.00)/5 = 18.50/5 = 3.70
Each passenger in a group of 5 friends pays $3.70 for the 10-mile ride.
_____
Additional comment
Each expression can be divided out to give ...
classic cost per person = $0.4375 +0.25d
XL cost per person = $0.70 +0.30d
Comparing these, we see there is no positive value of d that will make the XL cost per person be less than the classic cost per person. Both the initial fee and the per-mile cost are lower for the classic.
