Protozoa are single-celled organisms. Paramecium aurelia is one type of protozoan. The number of paramecium aurelia doubles every 1.25 days. There was one protozoan on a slide 5 days ago. How many are there now?
Answer:
16 days
Step-by-step explanation:
Given that:
Number of paramecium Aurelia doubles every 1.25days
5 days ago ; number of paramecium Aurelia = 1
How many are there now?
Using the relation :
Multiplier^(total number of days / time it takes to multiply)
Multiplier = doubles = 2
Total number rof days =. 5
Time it takes to. Multiply = 1.25
The formula becomes :
Number(n) of ptotozoan in 5days is given by 2^(5/1.25)
n = 2^(5/1.25)
n = 2^4
n = 2 * 2 * 2 * 2 =. 16

Step-by-step explanation:
Julie earned $130 one week and $125.50 the next week. After depositing these amounts in her account, she had a total of $335.
How much was already in her account before she deposited the $130 and $125.50?
Answer:
she had more than me
Step-by-step explanation:
Answer: $79.50
Step-by-step explanation:
Add together $130 and $125.50 to find out how much she deposited.
$130+125.50=$255.50
Now subtract the amount that was deposited from the total amount in her account.
$335−$255.50=$79.50

The area of a triangle is 120-meter square, if the height is equal 10 meter, what is the value of the base?
Answer:
24 meters
Step-by-step explanation:
The equation for the area of a triangle is A=1/2BxH where B is the base and H is the height. You are given the area and the height so you need to plug those values into the equation and solve.
120=1/2Bx10
240=Bx10
24=B

Whatbis the slope of a line that is perpendicular to the line y= 2x-6? A. -2
B. 2 C. 1/6 D. -1/2
Answer:
D. -1/2
Step-by-step explanation:
When a line is perpendicular to another line the slope will be the exact opposite. For example line A = y = 3x + 5 the line perpendicular to it will be -1/3x.
So -1/2 is the slope of your perpendicular line.

You decide to build a rectangular garden in your backyard. You've designated an area of 180m^2 for your garden. Due to the configuration of your backyard, the width of the garden must be 8 meters less than the length.
Answer:
[tex]Length = 18m[/tex]
[tex]Width = 10m[/tex]
Step-by-step explanation:
Given
[tex]Area = 180m^2[/tex]
[tex]Width = Length - 8[/tex]
Required
Determine the Length and the Width
Represent Width with W and Length with L;
So, we have:
[tex]Area = L * W[/tex]
[tex]Area = L * (L - 8)[/tex]
[tex]180 = L * (L - 8)[/tex]
[tex]180 = L^2 - 8L[/tex]
[tex]L^2 - 8L - 180 = 0[/tex]
Expand
[tex]L^2 - 18L + 10L- 180 = 0[/tex]
[tex]L(L - 18) + 10(L- 18) = 0[/tex]
[tex](L + 10)(L- 18) = 0[/tex]
Split
[tex]L + 10 =0[/tex] or [tex]L - 18 = 0[/tex]
[tex]L = -10[/tex] or [tex]L = 18[/tex]
But length cant be negative:
So,
[tex]L = 18[/tex]
Recall that:
[tex]Width = Length - 8[/tex]
[tex]W = 18 - 8[/tex]
[tex]W = 10[/tex]
Hence:
[tex]Length = 18m[/tex]
[tex]Width = 10m[/tex]
The dimension of the rectangular garden is 8m by 10m
The formula for calculating the area of the rectangular garden is expressed as;
A = lw
l is the length
w is the width
If the width of the garden must be 8 meters less than the length, then;
w = l - 8
Substitute into the formula;
180 = l(l-8)
180 =l^2 - 8l
l^2-8l - 180 = 0
Factorize the result;
l(l+10)-8(l+10) = 0
(l-8)(l+10)=0
l = 8 and -10
Since A = lw
w = A/l
w = 180/8
w = 10
Hence the dimension of the rectangular garden is 8m by 10m

Taino went to a professional basketball game. He spent $54.85 for a ticket, $4.99 for a hot dog, and $2.15 for a soda. What is the total amount that he spent? Use mental math to find the sum. O A. $60.99 O B. $61.00 O C. $61.99 O D. $62.00
Answer:
$61.99
Step-by-step explanation:
Based on everything that Taino bought his total amount would be $61.99 . Mental math would mean that no work is shown but for the sake of explanation, I can try to show how to derive the value from the answer choices given quickly. First, we see that the cents in each purchase do not equal a round dollar value when added so the answer must be either A or C. Secondly we add the dollar values and see that it surpasses the round value of 60 making the answer C.

Points B and B' have symmetry with respect to P. Find the coordinates of P when B is (2, 8) and B' is (2, 2). A. (2, 5) B. (0, 5) C. (5, 2)
Answer:
A. (2, 5)
Step-by-step explanation:
If B and B' have symmetry, then P is a midpoint between those points. We can determinate the location of point P by using the midpoint equation, whose vectorial form is:
[tex]P(x,y) = \frac{1}{2}\cdot B(x,y)+\frac{1}{2}\cdot B'(x,y)[/tex] (Eq. 1)
If we know that [tex]B(x,y) = (2,8)[/tex] and [tex]B'(x,y) = (2,2)[/tex], then the location of P is:
[tex]P(x,y) = \frac{1}{2}\cdot (2,8)+\frac{1}{2}\cdot (2,2)[/tex]
[tex]P(x,y) = (1, 4)+(1,1)[/tex]
[tex]P(x,y) = (2, 5)[/tex]
