Answer:

The answer of this question is $68.

Answer:

Step-by-step explanation:

Scale factor  = 1 : 7

a)Let the length of the house in the scale drawing = x

1:7 :: x : 21

Product of means = Product of extremes

 7*x = 1* 21

     x = [tex]\frac{1*21}{7}[/tex]

     x = 3

Length of the house in the scale drawing = 3 in

b) Height of the real house =y

1 : 7 :: 4 : y

Product of extremes = product of means

1 * y = 7*4

   y = 7*4

   y = 28

Height of real house = 28 feet

Step-by-step explanation:

Answer:

x = 45

Step-by-step explanation:

Interior angles of a triangle sum up to 180

180 - 90 = 90

90 / 2 = 45

Answer:

X = 45

Step-by-step explanation:

Since all interior angles of a triangle add up to 180 and both of the missing angles are the same value, X would equal 45,

90+45+45=180

Answer:

Step-by-step explanation:

Given points A ( 1 , - 2) and B ( 5 , 4)

Mid point of AB is

= (  ( x1 +x2)/ 2     ,    ( y1+ y2)/ 2  )

= (  ( 1 + 5)/2        , ( - 2 + 4)/2  )

= ( 3 , 1 )

Answer:

1145

Step-by-step explanation:

830(2) 28/13

​   ^ do that ok??????? plug it in!!!!!!!!

then do u know what u will get? u will get this !!!!!! y = 1145.09631989

round 2 da whole numba and den boom shakalaka B ) i got my question wrong so that i could put the right answer here. bye yall

The number of bacteria doubling every 28 hours will be 1145 after 13 hours.

The formula for exponential growth is y = y₀.e^(kt).

The formula for exponential decay is y = y₀.e^(-kt).

In the case of doubling the growth of bacteria, we can use the formula,

[tex]y_f = y_0\times2^{\frac{t_r}{t}[/tex], where [tex]y_f[/tex] represents the final population, [tex]y_0[/tex] is the initial population, [tex]t_r[/tex] is the time we are required to determine, and [tex]t[/tex] represents the time rate growth.

Therefore from the given information, the number of bacteria after 13 hours will be,

[tex]y_f = 830\times2^{\frac{13}{28}[/tex].

[tex]y_f = 830\times1.38[/tex].

[tex]y_f = 1144.86[/tex] or 1145 bacterias.

Q. In a lab experiment, 830 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to double every 28 hours. How many bacteria would there be after 13 hours, to the nearest whole number?​

Answer: 52.8 kilometers

Step-by-step explanation:

This week she plans to run 2²/₅ times as much as last week.

If she ran 22 kilometers last week, then multiple 22 by 2²/₅ to find out the number of kilometers to run this week.

First convert the improper fraction to a proper one:

2²/₅ = 12/5

= 12/5 * 22

= 264/5

= 52.8 kilometers

Names of Degrees

Degree Name Example

1 Linear x+3

2 Quadratic x2−x+2

3 Cubic x3−x2+5

4 Quartic 6x4−x3+x−2

Answer:

Quartic Trinomial

Step-by-step explanation:

Monomial = one term

Binomial = two terms

Trinomial = three terms

Polynomial = four or more terms

As the other answer says, the order for degrees is:

Linear - to first degree

Quadratic - to second degree

Cubic - to third degree

Quartic - to fourth degree

Quintic - to fifth degree

Anything above fifth degree is just said "__th degree"

Example: x^7 + x^2 + 5 would be seventh degree trinomial

Let x equal the number of cones

Answer:

8

Step-by-step explanation:

= f (x) = -2 log 4 (x + 5) - 4

= 4 (-2 + 5) - 4

= So you do -2 + 5 because they are in ( ) so you do it first so (-2 + 5) = 3

= So now you have 4 (3) - 4

= You do 4 and (3) because when you have a 4 by a ( ) that means you multiply.

= 4 (3) which is the same as 4 × 3 which is 12.

= then you do 12 - 4 which is 8.

= 8 is your answer.

I hope this helps.

Answer:

you'll have to multiply 8 by itself to get your area so you have to do 8*8
