Answer:
113.33 km/hr
Step-by-step explanation:
Given that :
From Austin
Drive 1 : Speed of 120km/hr for 1.5 hours
Stop time = 0.5 hour
Drive 2 : speed of v2 for 45 minutes to finally reach Houston
Total distance (Austin to Houston) = 265 km
Total distance : (distance on drive + distance on second drive)
Distance = speed * time
(120 * 1.5) + (v2 * 45/60) = 265
180 + 0.75v2 = 265
0.75v2 = 265 - 180
0.75v2 = 85
v2 = 85 / 0.75
v2 = 113.33km/hr
v2 = 85 / 0.75
v2 =

Using division property,
The rules for division are:
(1) positive × or ÷ positive = positive
(2) positive × or ÷ negative = negative
(3) negative × or ÷ negative = positive
Rule for long division method,
Divide the tens column dividend by the divisor.
Multiply the divisor by the quotient in the tens place column.
Subtract the product from the divisor.
Bring down the dividend in the ones column and repeat.
Therefore,
divide, multiply, subtract, bring down and repeat or find the remainder.

The mayor of a town places a map of the town on a coordinate grid with Town Hall at the point (0,0) and with each unit representing a mile. Smithville is at the point (-25,10) and Jones City is at (15,12). It costs $0.18 a mile to drive a car. How much does it cost to drive from Smithville and Jones City?
Answer:
Given that the question rightly asks the amount it cost to drive from Smithville to Jones City, we have;
The question rightly asks the amount it cost to drive from Smithville to Jones City is approximately $7.209
Step-by-step explanation:
The coordinates of Smithville is (-25, 10)
The coordinates of Jones City is (15, 12)
The cost of driving a car for a mile = $0.18
Therefore, the distance from Smithville to Jones City is given by the formula for the distance, l, between two points with coordinates as follows;
[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
Where;
(x₁, y₁) = (-25, 10) and (x₂, y₂) = (15, 12)
[tex]l = \sqrt{\left (12-10 \right )^{2}+\left (15-(-25) \right )^{2}} = 2 \cdot \sqrt{401}[/tex]
The distance from Smithville to Jones City = 2·√401 ≈ 40.05 miles
The amount, A, it cost to drive from Smithville to Jones City a distance of approximately 40.05 miles is therefore given as follows;
A = 40.05 miles × $0.18 ≈ $7.209

One key thing to note about a reflection is that side lengths and angle measures will always remain the same on the reflected figure. With that in mind, let's note the side lengths in both the original and reflected figures.
[tex]AB=\\BC=20\\CD=30\\AD=[/tex]
[tex]A'B'=22\\B'C'=\\C'D'=\\A'D'=32[/tex]
Remember, since side lengths are the same, let's fill in the missing values with the values of the side lengths given in each of the figures:
[tex]AB=22\\BC=20\\CD=30\\AD=32[/tex]
[tex]A'B'=22\\B'C'=20\\C'D'=30\\A'D'=32[/tex]
See? Notice how the values are the same! To find the perimeter ([tex]P[/tex]) of a quadrilateral, we have to add each side length:
[tex]P=22+20+30+32[/tex]
Solve:
[tex]P=104[/tex]

Cody started a fire in a field. The fire was expanding outward in all directions forming a larger and larger circle. The radius of the circular fire was 10 feet and was increasing at 2 feet/minute when Cody called the fire department. How many minutes will it take from the time Cody called the fire department until the area of the circular fire is 45401 square feet? Type your answer to the nearest hundredth (2 decimal places).
Answer:
55.10minStep-by-step explanation:
This problem is on the mensuration of flat shapes.
given that the initial radius before Cody alerted the fire department is
10 ft
Then we can calculate the area of the fire as
Area= πr^2
Area=3.142*(10)^2
Area=3.142*100
Area=314.2ft^2
Also, given that the area of the circular fire has grown to 45401 square feet
let us solve for the radius first, then we can calculate the time taken since the radius was increasing by 2 ft/min
let the radius of the large fire be R
45401=πR^2
R^2=45401/3.142
R^2=14449.714
square both sides we have
R=√14449.714
R=120.2ft
The difference between the radius of the initial fire and the large fire is
R-r=120.2-10
=110.2ft
Hence the time taken can be calculated as
time= 110.2/2
time=55.10min

This question is not complete
Complete Question
Carson is a high school student with two part-time jobs. He earns $6 per hour for babysitting, and he earns $8 per hour doing clerical work for his father's business. His goal is to earn at least $96 a week, but because of school, he does not want to work more than 15 hours each week. Let b represent the number of hours Carson works in one week at the babysitting job, and let c represent the number of hours Carson works in one week at his father's business. Which inequalities represent the constraints on what Carson can earn and the number of hours he can work in one week? Select all that apply.
A) b+c≤15
B) 6b+8c≤15
C) 6b+8c≥15
D) b+c≥96
E) 6b+8c≥96
F) 6b+8c≤96
Answer:
A) b + c ≤ 15
E) 6b + 8c ≥ 96
Step-by-step explanation:
Let b represent the number of hours he can work babysitting
Let c represent the number of hours he can work clerical work
We can derive 2 inequality equations
From the question, we are told:
He does not want to work more than 15 hours each week because of school
This means the maximum he wants to work is 15 hours, meaning he can work less than that. So we used the inequality less than or equal to Hence:
b + c ≤ 15...... Equation 1
He earns$6 per hour for baby sitting,and he earns $8 per hour doing clerical work for his father's business.His goal is to earn atleast $96 a week.
This means $96 is the least amount he wants to earn , meaning he can earn more than that. So we used the inequality greater than or equal to
Hence:
$6 × b +$8 × c ≥ $96
6b + 8c ≥ 96
Therefore, the two inequalities that represent the constraints on what Carson can earn and the number of hours he can work in one week:
A) b + c ≤ 15
E) 6b + 8c ≥ 96
The length of a rectangular garden is 5 meters shorter than twice it width, the area of its region is 150 square meters. Find the dimensions of the garden?
What is the formula?
Step-by-step explanation:
length = x - 5
width = 2x
2x(x-5) = 150 m^2
2x^2 - 10x = 150 m^2
2x^2 - 10x - 150 = 0
(x=11.51 or x = -6.513)
if you wanna check,
2(11.51) × (11.51-5) = 150
23.02 × 6.51 = 150
149.8602 = 150
I'm not sure if its correct though^^
