Answer:

Step-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

Answer:

6 over 9 is the simplest term

Step-by-step explanation: 4+2over9 = 6 over 9

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^^

Step-by-step explanation:

Answer:

1) -0.005

2) -1/2

3) 2

Step-by-step explanation:

The opposite of a number is the negative version of that number. The opposite of 0.005 is -0.005. The opposite of 1/2 is -1/2. Because 0 is not positive or negative, it stays the same, which is 0. I hope this helps :)

Answer:

1. - 0.005

2. - 1/2

3. 0

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

Step-by-step explanation:

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]

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 answer is 3.6

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.

Here the required value is of :

20/3

= 12/14

Divide numerator and denominator by 2
