Answer:

The Subtotal cost of all the cakes before tax and delivery

Step-by-step explanation:

(21x+8.25y)

21 is the price of 1 large cake and X is the number of cakes they want to purchase not counting tax and delivery fee.

8.25 is the price of 1 small cake and Y is the number of cakes they want to purchase not counting tax and delivery fee.

Answer:

Y(n) = 400(2.5)^n

Y = 3,814,697 rice weevils

16.1 weeks

Step-by-step explanation:

To predict the population of rice weevil for any week after the start of the study ; wwe use an exponential function for this purpose :

y(n) = A(1 + r)^n

Where;

Y(n) = population at week n

r = growth rate ; n = number of weeks

A = initial population at the start of the study

r = 150% = 1.5

Hence, we have the equation :

Y(n) = 400(1 + 1.5)^n

Y(n) = 400(2.5)^n

B.)

Population after 10 weeks

n = 10

Y(10) = 400(2.5)^10

Y = 400 * 9536.7431640625

Y = 3814697.265625

Y = 3,814,697 rice weevils

C)

When population will reach 1,000,000,000

We have :

1,000,000,000 = 400(2.5)^n

1000000000 / 400 = 2.5^n

2500000 = 2.5^n

Take the log of both sides :

log(2500000) = nlog(2.5)

6.3979400 = n * 0.3979400

n = 6.3979400 / 0.3979400

n = 16.077649

n = 16.1 weeks approximately

Answer:

Answer:

Plane

Step-by-step explanation:

There are three undefined geometric terms:

1. Point: A point is just a location. It has no size.

2. Line: A line has no width and extends infinitely in one dimension.

3. Plane: A plane extends infinitely in two dimensions.

So the answer is plane.

Answer:

[tex]f(6)=-21\\\\g(-3)=-52[/tex]

Step-by-step explanation:

When given the following two functions,

[tex]f(x) =-3x-3\\g(x)=2x^3+2[/tex]

One is asked to evaluate the functions for, (f(6)) and (g(-3)). One can do this by substituting the values (6) into the function (f) and (-3) into the function (g). These values will replace the parameter (x).

[tex]f(6)=-3(6)-3\\[/tex]

Simplify,

[tex]f(6)=-18-3\\f(6)=-21[/tex]

Now repeat this process for the guncion (g(x)) to evaluate for (g(-3))

[tex]g(-3)=2(-3)^3+2[/tex]

Simplify,

[tex]g(-3)=2(-27)+2\\g(-3)=-54+2\\g(-3)=-52[/tex]

Answer:

Drinking coffee and drinking water are independent events because

P(A|B)=P(A)and P(B|A)=P(B)

Step-by-step explanation:

Drinking coffee and water are independent events. People can choose to have both, none or any one. It is on their own will. Those who drink coffee can also drink water. The total of people who drink coffee may include those who drink water also.

Answer:

The answer is "0.869"

Step-by-step explanation:

Number of sample [tex](n) = 84[/tex]

Number of correct response [tex](X) = 73[/tex]

Calculating the Sample proportion:

Formula:

[tex]\text{Sample proportion}=\frac{\text{number of sample}}{\text{correct responses}}[/tex]

                              [tex]=\frac{n}{X}\\\\= \frac{73}{84} \\\\=0.869[/tex]

Answer:

21:50

Step-by-step explanation:

We need to find the ratio of 420 m to 1 km.

We know that,

1 km = 1000 m

So,

The ratio becomes,

[tex]\dfrac{420\ m}{1\ km}=\dfrac{420\ m}{1000\ m}\\\\=\dfrac{42\ m}{100\ m}\\\\=\dfrac{21}{50}[/tex]

So, the required ratio is 21:50.

Answer:

15x+30y-220

Step-by-step explanation:

Answer: 1: Combine multiplied terms into a single fraction

2: Multiply the numbers

3: Add the numbers

4: Solution

= 43/2

Step-by-step explanation:

Answer:

v = 43/2.

Step-by-step explanation:

2/7v - 1/7 + 14 = 20

2/7 v = 20 - 14 + 1/7

2/7 v = 6 1/7

2/7 v = 43/7

v = 43/7 / 2/7

v = 43/7 * 7/2

v = 43/2

Answer:

a) Median Height = 66 inches

b) Range of Heights = 18 inches

Step-by-step explanation:

a) The median in a box-and-whisker plot is the second quartile, located between the first and third quartiles indicated by the dashed line. Therefore, the median height is 66 inches.

b) The range in a box-and-whisker plot uses the same process of finding the range of a set of data. You find the difference between the maximum and the minimum values of the data. Therefore, the range of heights is 77 - 59 = 18 inches.

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

Explanation:

Angles EGD and BGF are vertical angles. Both are unknown and equal to x.

Notice how angle AGD is adjacent to angle CGD. These two angles form a straight angle (180 degrees) and angle CGD is a right angle. That must mean AGD is also a right angle.

Angles AGE and EGD must add to 90 degrees since AGD is 90

----------

(angleAGE)+(angleEGD) = (angle AGD)

(30) + (x) = 90

x = 90-30

x = 60

Answer:

The triangle's perimeter is 61.77 inches.

Step-by-step explanation:

Since an altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles, and as a result, the altitude cuts the base into two equal segments, and the length of the altitude is 26 inches, and the length of the base is 9 inches, to find the triangle's perimeter the following calculation must be performed:

Isosceles triangle = 2 equal sides

To obtain the value of the sides, the Pythagorean theorem must be applied on the right triangle formed with the altitude.

(9/2) ^ 2 + 26 ^ 2 = X ^ 2

4.5 ^ 2 + 26 ^ 2 = X ^ 2

20.25 + 676 = X ^ 2

√ (20.25 + 676) = X

√696.25 = X

26.38 = X

26.3865 x 2 + 9 = X

52.77 + 9 = X

61.77 = X

Therefore, the triangle's perimeter is 61.77 inches.

Answer:

C

Step-by-step explanation:

Both models represent half of the gymnasium, its just that one is vertical and one is horizontal. Both are basically correct. C is the right answer since it says both models are correct. Each class also does occupy 1/12 of the gymnasium since they get 1/6 of 1/2 of the gymnasium. Of means multiply so 1/6 * 1/2 = 1/12.
