Answer: After 13 (12) hours, there would be 6,500 bacteria across the culture.
Step-by-step explanation:
The bacteria grew by 500 each 4 hours, so to know how much there would be 13 hours later:
Simple, add 500 bacteria to every 4 hours until you reach 13 hours. 4 = 5.5k, 8 = 6k, 12 = 6.5k. Now, 12 is closer to 13 than anything we would've gotten if we kept going.
And there's your answer.
Which of the following expressions represents a value greater than 4/5 ?
Answer:
For the two fractions 4/5 and 5/6, the least common denominator is 30. The fraction 4/5 is equivalent to 24/30 (To get this I multiplied both the numerator and denominator by 6). ... Since 25 is greater than 24, 25/30 (or originally 5/6) is the larger fraction
Step-by-step explantion
Compare fractions with the same denominator by determining the relationship between the numerators. For example, 3/5 is less than 4/5 because 3 is less than 4

Find the remainder when x^100 - x^99 + x^98 − · · · − x + 1 is divided by x + 1.
Answer:
The remainder is 101.
Step-by-step explanation:
We are dividing:
[tex](x^{100}-x^{99}+x^{98}...-x+1)\div(x+1)[/tex]
By the Polynomial Remainder Theorem, if we are dividing a polynomial P(x) by a binomial in the form (x - a), the our remainder will be P(a).
The divisor is (x + 1). Therefore, our a = -1.
Then the remainder will be:
[tex]P(-1)[/tex]
We can rewrite our polynomial as:
[tex]P(x)=-(x^{99}+x^{97}...+x^3+x)+(x^{100}+x^{98}...+x^2)+1[/tex]
Each of the parentheses contain fifty terms. -1 to any odd power is -1, and -1 to any even power is 1. Therefore:
[tex]P(-1)=-(-50)+(50)+1[/tex]
Evaluate:
[tex]P(-1)=101[/tex]
The remainder is 101.
Answer:
The Answer is 101
Step-by-step explanation:

A remodeling project calls for sanding a chair with a disk sander. The sanding disk used on the sander has a radius of 4 inches. Find the area of the disk. Use 3.14 for \large \pi
Answer:
the area of the disk is 50.24 inches^2
Step-by-step explanation:
The computation of the area of the disk is as follows:
As we know that
The area of the circle is
= πr^2
= 3.14 × 4^2
= 3.14 × 16
= 50.24 inches ^2
hence, the area of the disk is 50.24 inches^2

x = 70°, y = 30°, z = 20°
Step-by-step explanation:
Right triangle have a total internal angle of 180°.
x = 180° - 110°
= 70°
z = 180° - 90° - x
= 180° - 90° - 70°
= 20°
y = 180° - 40° - 90° - z
= 180° - 40° - 90° - 20°
= 30°

Rita is designing a building shaped like a pyramid that's cut off in a plane parallel to its base (this is called a truncated pyramid).The building has a 64 × 64 m square base and is 36 m tall. The cut off section has a 16 × 16 m, square base and is 12 m tall. What is the volume of the buliding?
Answer:
65,536−1,024
which = 64,512 m^3
Step-by-step explanation:
I took the test!
The volume of the building shaped like a pyramid that's cut off in a plane parallel to its base is 64512 m³
Volume of a pyramidvolume of a pyramid = 1 / 3 Bh
where
B = base areah = height of the pyramidTherefore,
volume of the building = volume of the whole figure - volume of the cut part
volume of the whole figure = 1 / 3 × (64 × 64) × (12 + 36)
volume of the whole figure = 65536 m³
volume of the cut part = 1 / 3 × (16 × 16) × (12)
volume of the cut part = 1024 m³
Therefore,
volume of the building = 65536 - 1024 = 64512 m³

What is the equation of a line perpendicular to the x-
axis that passes through the point (-5,-1)? What is the
slope of this line?
Answer:
The equation is x = -5
The slope is 0
Step-by-step explanation:
If the line is perpendicular to the x axis, that means it is a vertical line.
Vertical lines only reach one x value, which is -5 in this case.
So, the equation will simply be x = -5.
The slope is 0.

Suppose your school costs for this term were $4780 and financial aid covered 3/4 of that amount. How much did financial aid cover? How much do you still have to pay?
Answer: Amount covered by financial aid=$3,585
Amount left that you have to pay =$1,195
Step-by-step explanation:
School cost for the term = $4780
Amount covered by financial aid = 3/4 of $4780
= 3/4 x 4780
Amount left that you have to pay=School cost for the term -Amount covered by financial aid
= $4,780 - $3,585
Amount left that you have to pay =$1,195

Answer:
The cheerios are more expensive per ounce
Step-by-step explanation:
6. 22 ounce box of Cheerios cost $2.79---$0.45
A 32 ounce box of Wheaties cost $3.50----$0.11
2.79/6.22 =0.45

Eyan bought 234 pounds of apples for $1.32 per pound, 112 pounds of peaches for $1.20 per pound, and some tomatoes, all from a grocery store. The total cost of his purchase was $9.63. How much money did Leyan spend on tomatoes?
Answer:
the money spend on tomatoes is $4.20
Step-by-step explanation:
The computation of the money spend on tomatoes is shown below
Let the money spend on tomatoes be x
So
[tex]2 \frac{3}{4} \times \$1.32 + 1\frac{1}{2} \times \$1.20 + x = \$9.63\\\\[/tex]
$3.63 + $1.80 + x = $9.63
x = $9.63 - $3.63 + $1.80
= $4.20
Hence, the money spend on tomatoes is $4.20
Tina has an old fish tank in the shape of a circular cylinder. The tank is 2 feet in diameter and 6 feet high. How many cubic feet of water does it hold?
Answer:
The tank can hold 18.84 cubic feet
Step-by-step explanation:
Given
Shape: Cylinder
[tex]D = 2ft[/tex] -- Diameter
[tex]H = 6ft[/tex] -- Height
Required
Determine the volume
First, calculate the radius (r)
[tex]r = \frac{1}{2}D[/tex]
[tex]r = \frac{1}{2}*2ft[/tex]
[tex]r = 1ft[/tex]
The volume (V) of the tank is:
[tex]V = \pi r^2h[/tex]
Substitute values for r and h
[tex]V = 3.14 *1^2*6[/tex]
[tex]V = 3.14 *1*6[/tex]
[tex]V = 18.84[/tex]
Hence, the tank can hold 18.84 cubic feet

is 3 1/2 greater than 1 1/15
Answer:
Yes
Step-by-step explanation:
The whole number in 3 1/2 is 3
the whole number in 1 1/15 is 1
Since 1 1/15 isn't an improper fraction, if it's whole number is smaller then the whole fraction is smaller
since 3>1, 3 1/2 is greater than 1 1/15
Answer:
31/2 > 11/15
Step-by-step explanation:
Question: Is 31/2 greater than 11/15 ?
To solve this let us convert the fractions to decimals.
31/2 = 15.5
11/15 = 0.733
With a look we can easily say that 31/2 is indeed greater than 11/15.
So, 31/2 > 11/15.
