(I NEED THE ANSWER ASAP)

What is difference between the mean number of boxes sold during the first 4 months of last year and the first 4 months of this year?

The population after 516 minutes is 171360 bacteria

From the question, we have the following parameters that can be used in our computation:

Initial, a = 10,710 bacteria

Rate = doubles i.e. 2

Using the above as a guide, we have the following:

f(x) = a(2)^x

Where x is the time

516 minutes is 4 times 129 minutes

This means that

x = 516/129 = 4

So the population after 516 minutes can be calculated as follows:

f(4) = 10710 * (2)^4

Evaluate

f(4) = 171360

Hence, the population is 171360

We need indirectly m<POQ

See NR is a straight line so the three angles situated underneath are linear pair and supplementary

m<POQ

Answer:

C)  35°

Step-by-step explanation:

From inspection of the given diagram, it appears that the line segment NOR is the diameter of the circle (where point O is the center).

Angles on a straight line sum to 180°

⇒ ∠NOP + ∠POQ + ∠QOR = 180°

⇒ 82° + ∠POQ + 63° = 180°

⇒ ∠POQ = 180° - 82° - 63°

⇒ ∠POQ = 35°

As an arc measure equals its corresponding central angle measure:

[tex]\sf \implies \overset{\frown}{PQ}= \angle POQ[/tex]

[tex]\sf \implies \overset{\frown}{PQ}=35^{\circ}[/tex]

Answer:

Step-by-step explanation:

Circumference = 2(pi)r

Radius = Circumference/2(pi)

Circumference = 37.68

Radius = 37.68/2(pi)

Answer:

6 weeks

Step-by-step explanation:

Since Reggie has $240 in the account already we first subtract this $240 from the $450. 450 - 240 = 210. Now since he deposits $35 a week and needs to hit at least 210 to reach is goal of $450 for the summer then we need to divide 210/35 to see the amount of weeks.  210/35 = 6. So 6 weeks  is the shortest time.

Answer:

1 - 4/9

2 - 1/9

3 - 5/9

Step-by-step explanation:

1 - Look on the left side for all two-letter combinations with only one R. We can see four. (YR, GR, RG, RY). Divide by the total number of outcomes (9).

2 - There is only one with two yellows, so divide 1 by 9.

3 - Same as before, we find 4 with 1 green and 1 with 2 green. We have to include the new one since it says atleast one. Add 1 and 4 and then divide by 9.

Answer:

1/8

Step-by-step explanation:

I'd start by rearranging the terms for y:

11x-8y=-1

-8y=-1-11x

y=[tex]\frac{-1-11x}{-8}[/tex]

The x-intercept is found when x equals 0, so substitute 0 for x in this new equation to find the y-intercept:

[tex]y=\frac{-1-11x}{-8} \\y=\frac{-1-11(0)}{-8}\\ y=\frac{-1-0}{-8} \\y=\frac{-1}{-8}\\ y=\frac{1}{8}[/tex]

The y-intercept is 1/8

Answer:

f(x) = (x + 1)(x - 4)

Step-by-step explanation:

let f be the function

FACTORED FORM of f :

f(x) = a(x - p)(x - q)

Where p and q are the roots/zeros of f

and ‘a’ is a real number.

=================================

Find p and q :

The roots of f are the x-coordinates where the graph crosses the x-axis, which can be read from the graph: x = -1 and x = 4 ⇒ p = -1 and q = 4.

then f(x) = a(x + 1)(x - 4)

Find ‘a’ :

f(3) = -4  ⇒ a((3) + 1)((3) - 4) = -4 ⇒ a(4)(-1) = -4 ⇒ -4a = -4 ⇒ a = 1

Therefore, f(x) = (x + 1)(x - 4)

Answer:

width = 7 and length = 9

Step-by-step explanation:

Let's assume width = w, and length = 2 + w

So area of a rectangle = width * length

63 ft² = w (2 + w)

63 = 2w + w²

w² + 2w - 63 = 0

Use the quadratic formula to solve this

here, a = 1, b = 2 and c = -63

w = 7 or -9

The dimensions of a rectangle cannot be negative. So we take the dimension, w = 7.

Width = 7 and Length = 7+2 = 9

Answer:

La respuesta es A

Step-by-step explanation:

simplemente tienes que multiplicar 7 x 3 que te da 21 y luego tienes que sumar el 2 del numerador (siempre multiplica el o los enteros por el denominador y sumale el numerador)

Answer:

A

Step-by-step explanation:

The larger number in a mixed number represents how many "wholes" of the fraction there are. The fraction in a mixed number is sort of like the "leftovers", the amount that doesn't fit into a whole number. In this case, the whole number is 7, meaning there are 7 amounts of 3/3. You would multiply the whole number by the number in the denominator of the fraction, which would equal 21. The improper fraction of the whole number would be 21/3 (21 divided by 3 equals 7). Now you would add that to the fraction 2/3. The answer would be 23/3.

I hope this makes some type of sense, I didn't explain it very well.

Answer:

Given:

To construct the Venn diagram:

As 2 students study neither subject, place the number 2 in the box outside the circles.

Calculate the number of students who study both subjects (central overlapping section):

Physics students + Chemistry students + neither students - Total students

= 20 + 18 + 2 - 35 = 5

Place the number 5 in the central overlapping section.

⇒ Left section = Physics students - both subjects

                        = 20 - 5

                        = 15

⇒ Right section = Chemistry students - both students

                          = 18 - 5

                          = 13

i) See attachment

ii) Physics and Chemistry = 5 students

iii) Physics only = 15 students

iv) One subject only = 15 + 13 = 28 students

1³ + 2³ + 3³

1 + 8 + 27

Answer:

433.5 cm^3

Step-by-step explanation:

The volume of a cylinder is its base area times height. Therefore it can be said that:

V = 23π x 6

This is 433.539786195, which when rounded to the nearest tenth is 433.5.

Answer:

A trapezoid is a quadrilateral that has two parallel sides with a height.

From the diagram, AK = 1/2(AD-BC)

The combination of the bases of the equilateral triangle and the parallelogram is = the base of the trapezoid.

Therefore, BC = AD - 2AK

Make AK the subject of formula,

AK= 1/2 (AD -BC)

KD = 1/2(AD - BC). This is wrong because of the following,

BC is parallel to KD.

Therefore length of KD = BC - AK and not KD = 1/2(AD - BC).
