A culture is tested for bacteria and has 3.3 million bacteria. The culture is then tested every 10 minutes and each time it is tested there are 2.5 times more bacteria.
How many bacteria in millions will there be in the culture after 30 minutes?
Round to the nearest hundredth.
8.25
75.00
51.56
115.00
Answer:
C. 51.56 millionStep-by-step explanation:
Initial number of bacteria = 3.3 millionGrowth rate = 2.5 times per 10 minutesTime = 30 minutes = 3*10 minutesNumber of bacteria after 30 minutes:
3.3*2.5³ = 51.5625Correct choice is C
Answer:
after 10 minute total bacteria=2.5×3.3=8.25 millions
in 1 minute total bacteria=2.5×3.3/10 =0.825millions
in 30 minute total bacteria=30×2.5×3.3/10 millions=24.75million is your answer.but i did not get any match.
What is the value of w?
Answer:
14
Step-by-step explanation:
this is a 30-60-90° Δ and the sides, respectively, have the ratio of 1 : [tex]\sqrt{3}[/tex] : 2
we can set up a proportion and cross-multiply based on that ratio:
w / 7[tex]\sqrt{3}[/tex] = 2 / [tex]\sqrt{3}[/tex]
[tex]\sqrt{3}[/tex]w = 14[tex]\sqrt{3}[/tex]
w = 14
Avery is preheating her oven before using it to bake. The initial temperature of the
oven is 65° and the temperature will increase at a rate of 10° per minute after being
turned on. What is the temperature of the oven 7 minutes after being turned on?
What is the temperature of the oven t minutes after being turned on?
Answer:
temp after 7 minutes is 135°
temp after 't' minutes: y = 65 + 10t
Step-by-step explanation:
Answer:
1) 135°
2) 65° + 10t°
Step-by-step explanation:
What is the temperature of the oven 7 minutes after being turned on?
65° (initial temperature) + 10° (temperature increase per minute) × 7 (amount of minutes)
10 × 7 = 70
65° + 70° = 135°
What is the temperature of the oven t minutes after being turned on?
65° (initial temperature) + 10° (temperature increase per minute) × t (amount of minutes)
10 × t = 10t
65° + 10t°

Step-by-step explanation:
Height of triangle (h) = 2.5 + 4 = 6. 5 cm
Base of triangle (b) = 3 + 3 = 6 cm
Radius of circle (r) = 4 cm
Required probability = Area of triangle/Area of circle
[tex] = \frac{ \frac{1}{2} bh }{\pi {r}^{2} } \\ \\ = \frac{ \frac{1}{2} \times 6 \times 6.5 }{3.14 \times {4}^{2} } \\ \\ = \frac{3 \times 6.5}{3.14 \times 16} \\ \\ = \frac{19.5}{50.24} \\ \\ = 0.388136943 \\ \\ \approx0.39[/tex]

(6x-1)°=(6(10)-1)° don’t know?
9514 1404 393
Answer:
x = 10
Step-by-step explanation:
You can compare parts of each expression to see that x in the left-side expression is replaced by 10 in the right-side expression.
x = 10
__
If you'd rather, you can work your way down to the same conclusion by undoing the operations that have been done to x.
(6x -1)° = (6(10) -1)° . . . . . . given
6x -1 = 6(10) -1 . . . . . . . . . divide both sides by °
6x = 6(10) . . . . . . . . . . . . add 1 to both sides
x = 10 . . . . . . . . . . . . . . . . divide both sides by 6

Answer:
The answer is 28
Step-by-step explanation:
Since the total measurements of triangle corners are equal to 180
Then
[tex]2x + 3x - 10 + 50 = 180 \\ 5x - 40 = 180 \\ 5x = 140 \\ x = 28[/tex]

Please Helpppppp!!!!! What is the value of x.
Answer:
Step-by-step explanation:
Remark
By corresponding angles and vertical angles, these two angles are equal.
Equation
-1 + 14x = 12x + 17 Subtract 12x from both sides
Solution
-1 + 14x - 12x = 12x - 12x + 17
-1 + 2x = 17 Add 1 to both sides
-1+1 + 2x = 17 + 1
2x = 18 Divide by 2
2x/2 = 18/2
x = 9
