What is the solution to the equation p + 7.2 = 11?
p = 3.2
p = 3.8
p = 4.8
p = 18.2
Answers
Answer:
p = 3.8
Step-by-step explanation:
11 - 7.2 = 3.8
Answer:
p = 3.8
Step-by-step explanation:
We have the equation p + 7.2 = 11 and are asked to solve for "p".
To do so, all we need to do is isolate p :
p + 7.2 = 11
Subtract 7.2 from both sides :
p = 3.8
A culture of bacteria has an initial population of 970 bacteria and doubles every 7
hours. Using the formula P+ = Po.2, where P is the population after t hours, Po
is the initial population, t is the time in hours and d is the doubling time, what is the
population of bacteria in the culture after 2 hours, to the nearest whole number?
Answers
Answer:1182.4432≈1182
Step-by-step explanation:
The population of bacteria in the culture after 2 hours is approximately 1,248.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
Given that the initial population of bacteria is [tex]P_0[/tex] = 970, and the doubling time is d = 7 hours.
Using the formula,
P+ = [tex]P_0[/tex] x [tex]2^{t/d)[/tex]
We can calculate the population of bacteria after 2 hours as follows.
P+ = 970 x [tex]2^{2/7}[/tex]
= 1,248.4
Rounding this to the nearest whole number, the population of bacteria in the culture after 2 hours is approximately 1,248.
Thus,
The population of bacteria in the culture after 2 hours is approximately 1,248.

Identify the percent of change as an increase or a decrease. Then find the percent of change. Round to the nearest tenth of a percent, if necessary: 120 pounds to 180 pounds
Answers
Answer:
50%
Step-by-step explanation:
We need to find the percent change from 120 pounds to 180 pounds. We can find it as follows :
[tex]\%=\dfrac{180-120}{120}\times 100\\\\=\dfrac{60}{120}\times 100\\\\=50\%[/tex]
So, the percent change is equal to 50%.
Which table does not represent a relationship that is directly proportional? Btw i clicked a by accident
Answers
Answer:
The selected option
Step-by-step explanation:
Coincidentally, you answered correctly.
From the values of 3 and five, we can assume that the function of the table is Y=x+2.
But if we move to the next value pairs, that function is false.
10=6+2 that isn't correct.
If you apply this to all the pairs in the table you will find that there is not a function that represents the values given. Therefore, the first option is correct.

the shape of the toy is a cylinder of radius 5 cm and height 8 cm on top of a hemisphere of radius 5cm calculate the volume of a toy
Answers
Answer:
889.66 cm^3
Step-by-step explanation:
here's your solution
=> radius of cylinder = 5 cm
=> height of cylinder => 8 cm
=> radius of hemisphere = 5 cm
=> volume of toy = ( vol of cylinder + vol of hemisphere)
=> volume of cylinder = πr^2h
=> putting value , = 22/7*5*5*8
=> volume = 628 cm^3
=> volume of hemisphere = 2/3πr^3
=> putting value , = 2/3*22/7*5^3
=> volume of hemisphere = 261.66 cm^3
=> volume of toy = (628 + 261.66)cm^3
=> volume = 889.66 cm^3

Answer:
The largest tile she can use is a 8 inches by 8 inches tile.
Step-by-step explanation:
Rosa is making a game board that is 16 inches by 24 inches.
She wants to use square tiles.
The area of the game board (area of a rectangle) is equal to length times width.
∴ Area = 16 inches × 24 inches = 384 square inches
The prime factors of 384 are; 2^7 × 3
We can put it as;
2^6 × 6 = 384
The square root of 2^6 is 2^3 = 8
So Rosa will need six square tiles of 8 inches by 8 inches each.
Hence the largest tile she can use is a 8 inches by 8 inches tile.

The equation for the number 40 is 5 times as many as 8 is; 40=5×8
What does it mean to solve an equation?An equation represents equality of two or more mathematical expression.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
Solutions to an equation are those values of the variables involved in that equation for which the equation is true.
We are given that the number 40 is 5 times as many as 8
40 is 5 times as many as 8 means
5×8 = 40
Then the equation will be;
40=5×8
