A team of researchers is monitoring the population of crickets in a particular town. They do not know exactly how many crickets are remaining, but the model they use represents the minimum number of crickets remaining in the town.
According to their model, the minimum number of the species remaining, in thousands, multiplies by 10 every month. The researchers determine that right now, the population of crickets is at least 5 thousand. Once the minimum population reaches 1 million, measures are taken to stop the increase in population.
If P represents the actual population of crickets in the town, in thousands, and t represents the time, in months, which of the following systems of inequalities can be used to determine the possible number of crickets in the town over time?
Answer:
P>_5(10)^t
P<_1,000

One angle in an obtuse isosceles triangle measures 40°. What are the measures of the other two angles?
40° and 120°
70° and 70°
40° and 100°
80° and 80°
Answer:
40° and 100°
Step-by-step explanation:
An obtuse triangle has one obtuse angle, or an angle that measures more than 90° but less than 180°. Options 1 and 2 are not correct, because these are acute angles.
So, one of the angles must be 40°, and the other may be 100° or 120°.
The measures of the angles in a triangle add up to 180°
40° + 40° + [tex]x[/tex] = 180°
80° + [tex]x[/tex] = 180°
[tex]x[/tex] = 180° - 80°
[tex]x[/tex] = 100°
The other two angles are 40° and 100°.

How many cubes with edge lengths of 1/4 in. will it take to fill the prism?
56 cubes
375 cubes
6000 cubes
Answer:
1560
Step-by-step explanation:
First (2 1/2)/(1/4) = (5/2)(4) = 20/2 = 10
Next, 3/(1/4) = 3(4) = 12
Lastly, (3 1/4)/(1/4) = (13/4) x 4 = 52/4 = 13
This means we need 10 rows of 12, 13 high. 10(12)(13) = 1560 cubes.
Another way is to multiply 2 1/2 x 3 x 3 1/4 = 5/2 x 3 x 13/4 = 195/8
A 1/4 inch cube is 1/4 x 1/4 x 1/4 for a volume of 1/64
(195/8)/(1/64) = (195/8)(64) = 1560 cubes.

A shipping company charges a flat rate of $3 and 1 cent for every mile traveled. What is the initial value and the rate of change?
Answer:
initial value = 3
rate of change = 0.01
Step-by-step explanation:
we can represent this as a linear equation:
y = 0.01x + 3
the initial value is the value of y when x = 0; we can find this by setting x to zero and evaluating for y, which gives us 3. Our initial value is 3.
The rate of change, of slope of this graph, is 0.01, as it is the constant multiplier of x.

8 Connor the fruiterer sells two fruit packs.
Pack 1: 10 apples and 5 mangoes ($12)
Pack 2: 15 apples and 4 mangoes ($14.15)
Determine the cost of 1 apple and 5 mangoes.
(Simultaneous equations) pleaseeee help me test tomorrow
The cost of 1 apple and 5 mangoes is $6.15.
Let's look at how to form and solve simultaneous equations in a word problem.
State assumption and define variables:Assuming that the cost of each apple and mango is equal in both packs.
Let the cost of an apple be a and that of a mango be m.
Write equations based on given information:10a +5m= 12 -----(1)
15a +4m= 14.15 -----(2)
Solve by elimination:Steps for solving equations with two variables
Ensure that the magnitude of the coefficients of one of the term is equal in both equationsEliminate the term with the chosen term through subtraction or additionSolve for the other termSubstitute the value of the term found in (3) to find the value of the second termWorking
Here, I am making the value of the coefficient of m constant.
(1) ×4:
40a +20m= 48 ----(3)
(2) ×5:
75a +20m= 70.75 -----(4)
Moving on to step 2, we can eliminate the m term by subtracting equation (3) from (4). When the sign of the terms are equal, we use subtraction to eliminate the term. On the other hand, if one of the sign is positive and the other is negative, adding the two equations together will eliminate the term (provided that you have already ensured that the magnitude of the coefficient is equal).
(4) -(3):
75a +20m -(40a +20m)= 70.75 -48
Expand:
75a +20m -40a -20m= 22.75
Simplify:
35a= 22.75
Let's continue with step 3, where we solve for a.
a= 22.75 ÷35
a= 0.65
The cost of an apple is $0.65.
Now, moving on to step 4!
Substitute a= 0.65 into (1):
10(0.65) +5m= 12
6.5 +5m= 12
5m= 12 -6.5
5m= 5.50
5 mangoes costs $5.50.
Cost of 1 apple and 5 mangoes
= $0.65 +$5.50
= $6.15
Thus, the cost of 1 apple and 5 mangoes is $6.15.

Hunter wants to make money over the summer by selling lemonade. He has $50 in savings. He spends 520 on a pitcher and reusable cups. Doing the math, he realizes that sugar, lemons, and water will cost $. 75 per serving. What is the greatest number of cups that can be made before Hunter runs out of his budget?
Hunter can make a maximum of 59 cups before he runs out of money.
What is an inequality?An inequality is an expression that shows the non equal comparison of two or more variables and numbers.
Let x represent the number of cups that hunter can buy, He already spent 520 cents ($5.2) hence:
0.75x ≤ 50 - 5.2

The average length of a female dolphin is about 181 inches (in).
What is this length in feet (ft) and inches (in)?
The length is ft in.
Answer:
15 ft 1 in
Step-by-step explanation:
To convert inches into feet, we divide by 12.
12 goes into 181 fifteen times, so the # of feet is 15 feet.12 x 15 = 180.181 - 180 = 1, so the # of remaining inches is 1 inchTherefore, the answer is 15 ft 1 in.
One graphic designer takes 3 hours to design a logo. Her less experienced
colleague takes 4 hours to design a logo. How many hours would it take them to
design a total of 7 logos if they both
start working at the same time?
It takes them 12 hours to design a total of 7 logos if they both start working at the same time
RateThis is the amount per unit time.
Since one graphic designer takes 3 hours to design a logo. Her less experienced colleague takes 4 hours to design a logo, we need to find the rate at which the work is done.
The rate at which the first graphic designer works is 1 logo/3 hours = 1/3 logo/hr.Also, the rate at which the less experienced colleague works is 1 logo/4 hours = 1/4 logo/hr.So, their combined rate r = 1/3 logo/hr + 1/4 logo/hr = (4 + 3)/12 logo/hr = 7/12 logo/hr.Time to design 7 logosNow, since we require the time to desigh 7 logos, this time is T = number of logos/combined rate
= 7 logos ÷ 7/12 logo/hr
= 12 hr
So, it takes them 12 hours to design a total of 7 logos if they both start working at the same time

Mr. Miller owns two hotels and is ordering towels for the rooms. He ordered 27 hand towels and 48 bath towels for a bill of $540 for the first hotel. He ordered 50 hand towels and 24 bath towels for a bill of $416 for the other hotel.
What is the cost of one hand towel and one bath towel?
A.
The cost of one hand towel is $9 and the cost of one bath towel is $4.
B.
The cost of one hand towel is $8 and the cost of one bath towel is $5.
C.
The cost of one hand towel is $5 and the cost of one bath towel is $8.
D.
The cost of one hand towel is $4 and the cost of one bath towel is $9.
This question is based on the concept of solving a two linear equation.
Thus, the cost of one bath towel is $9 and one hand towel is $4.
Given:
Number of ordered of hand towels is 27 and bath towels is 48 and for a bill of $540 for the first hotel.
Number of ordered of hand towels is 50 and bath towels is 24 and for a bill of $416 for the other hotel.
We need tom determined the cost of one hand towel and one bath towel.
According to the question:
Let the hand towels be h and bath towels be b.
Therefore, equation of first hotel is
27h + 48b = 540........(1)
Equation of second hotel is
50h + 24b = 416.........(2)
Now, solving both equation for h and b.
Equation (2) multiplying by -2.
-100 h -48 b = - 832..................(3)
Now, solve equation (1) and (3)
27h + 48b = 540 and -100h - 48b = - 832
⇒ -73 h = - 292
⇒ h = -292 / -73
⇒ h = 4
Therefore, the cost of 1 hand towel is $4.
Now, putting the value of h = 4 in equation (1).
⇒ 27(4) + 48b = 540
⇒ 108 + 48b = 540
⇒ 48b = 540 - 108
⇒ 48b = 432
⇒ b = 432/48
⇒ b = 9
Therefore, the cost of 1 bath towel is $9.
Thus, the cost of one bath towel is $9 and one hand towel is $4.
