do yall know what the answer to 4d(2d-9)

Answer:

Step-by-step explanation:

In order to determine the equation, consider that any exponential growth equation can be written as follow:

[tex]f(t)=A(1+r)^t[/tex]

where,

f(t): amount of bacteria after t hours

A: initial amount of bacteria  = 3

r: growth rate in decimal form = 0.15  (15%)

t: time in hours

By replacing the previous values into the expression for f(t) you get;

[tex]f(t)=3(1+0.15)^t\\f(t)=3(1.15)^t[/tex]

Hence, the answer is f(t) = 3(1.15)^t

Now, replace t = 13 to determine the amount of bacteria after 13 hours:

[tex]f(13)=3(1.15)^13\\f(13)=18.46[/tex]

Hence, after 13 hours there are approximately 18 bacteria

12 different calculators

total = types x colors

total = 4 x 3 = 12

Answer: 12

Answer:  1/20  or  one twentieth

Work Shown:

1/2 = one half

1/10 = one tenth

(1/2)*(1/10) = (1*1)/(2*10) = 1/20

Basically we multiply the 2 and 10 to get 20 in the denominator.

Answer:

option C

Explanation:

For Naomi's rectangular prism:

⇒ Length × Width × Height

⇒ 5 × 14 × 2

⇒ 140 cm³

For Ben's triangular prism:

⇒ 1/2 × Base × Height × Length

⇒ 1/2 × 5 × 4 × 14

⇒ 140 cm³

The prism's have the same volume.

Answer: Choice C

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

Explanation:

The volume of the rectangular block is:

V = L*W*H = 5*14*2 = 70*2 = 140 cubic cm.

Now move onto the triangular prism.

The triangular face has a base of 5 cm and height of 4, so the area of this face is

A = base*height/2 = 5*4/2 = 20/2 = 10 square cm

Multiplying this with the depth of the prism tells us the volume is

V = (area of the base)*(depth) = (10 sq cm)*(14 cm) = 140 cubic cm

Therefore, the prisms have the same volume.

Answer:

C. The typical value is greater in set B. The spread is greater in set A.

Step-by-step explanation:

A typical value is the center of the dot plot, which is often found by finding the mean or median of the set. Both sets have 5 dots plotted. The spread of a set is how far the plotted values are from this center (mean or median).

Set A is shown to have more data spread out; values range from 0 to 7.

Set B is shown to have data that is more condensed and at higher values; ranges from 6 to 9, with two of the five points plotted at 6.

Set B has a higher typical value. Set A has a greater spread.

Answer:

16 is equivalent to 2/3 therefore you just multiply by 3/2 because 2/3 times 3/2 gives you one which would give you the number of square feet per hour and x would be the amount of square feet per hour made. To show in steps...

16=2/3x

16(3/2)= 2/3 (3/2)

24=1 hour

Answer:

5.3

Step-by-step explanation:

its quite simple well for my sister but- Anyways hope this helps!

Answer:

We are given a perimeter and three different lengths and we need to determine the corresponding width and area.  

The first length that is provided is 2 feet and to get a perimeter of 16 feet which we can then use the perimeter formula to get 2(2 + 6) which gives us a perimeter of 16 feet and a width of 6 feet.  We can then get the area by multiplying the length by width which gives us 12 feet squared.

The second length that is given is 4 feet and to get a perimeter of 16 feet which we can then use the perimeter formula to get 2(4 + 4) which gives us a perimeter of 16 feet and a width of 4 feet.  We can then get the area by multiplying the length by width which gives us 16 feet squared.

The final length that is given is 5 feet and to get a perimeter of 16 feet which we can then use the perimeter formula to get 2(5 + 3) which gives us a perimeter of 16 feet and a width of 3 feet.  We can then get the area by multiplying the length by width which gives us 15 feet squared.

Therefore, the field that would require the most amount of paint (the largest area) is option B, region #2.

Answer:

S(A) = 306 in²

Step-by-step explanation:

The surface area of a rectangular prism can be found using the following equation:

SA(rectangular prism) = 2(wl + hl + hw)

Note:

w = width = 6

h = height = 12

l = length = 4.5

Plug in the corresponding numbers to the corresponding variables:

SA(rectangular prism) = 2((6 * 4.5) + (12 * 4.5) + (12 * 6))

SA(rectangular prism) = 2((27) + (54) + (72))

SA(rectangular prism) = 2(27 + 54 + 72)

SA(rectangular prism) = 2(153)

SA(rectangular prism = 306

S(A) = 306 in²
