Answer:

28 minutes

Step-by-step explanation:

40 percent is 0.4 and 100 percent is 1. Since you have the full 100% of 20 plus the increase of 40% you have to multiply by 20 by 1.4

1.4*20 = 28

How can you show that a generalization is likely correct
gtnhenbr [62]
You can't prove that generalization is likely correct. <em />It is told that generalization is never correct and some has told that generalization is sometimes correct, so I guess that would depend on your thoughts, opinions.
hope this helped!!

PLSSS HELP IF YOU TURLY KNOW THISS
Natalija [7]

Hello there!

11⁶/11²=11/⁴ because when we divide numbers with the same base, we subtract the powers.

11⁴*11⁵=11⁹ because we add the powers when multiplying numbers with the same base.

I hope this helps you!

What can you say about the y-values of the two functions <img src="https://tex.z-dn.net/?f=f%28x%29%20%3D%203%5Ex-3" id="TexForm
slavikrds [6]

Answer:

a) The minimum y-value of f(x) is -3

d) The minimum y-value of g(x) is -3

Step-by-step explanation:

Given in the question that,

f(x) = 3^{x}-3

g(x) = 7x² - 3

<h3>A)</h3>

At large negative exponents, the value approaches to zero

y = 3^{-100}-3=-3

y = 3^{-1000}-3=-3

y = 3^{-10000}-3=-3

<h3>B)</h3>

Minimum y-value of g(x) will be when x = 0

y = 7x² - 3

y = 7(0) - 3

y = -3

Find the slope of the equation of the line that passes through the given points. through: (0, -3) and (3, 4)
Nadya [2.5K]

Answer:

7/3

Step-by-step explanation:

The slope is found by dividing the difference in the y-coordinates by the difference in the x-coordinates.

Here, the difference in the y-coordinates is: 4 - (-3) = 4 + 3 = 7. The difference in the x-coordinates is: 3 - 0 = 3.

Dividing 7 by 3, we get a slope of 7/3.

Two combines are able to harvest 320 acres of crops in a certain amount of time. How many acres will (a)3, (b)4, (c)6 and (d)7 c
never [62]

Answer:

a) 480 acres

b)640 acres

c)960 acres

d)1120 acres

Step-by-step explanation:

Two combines are able to harvest acres of crops = 320

1 is able to harvest acres of crop = \frac{320}{2} = 160

Three combines are able to harvest acres of crops = 160 \times 3

                                                                                    = 480

Four combines are able to harvest acres of crops = 160 \times 4

                                                                                    = 640

Six combines are able to harvest acres of crops = 160 \times 6

                                                                                    = 960

Seven combines are able to harvest acres of crops = 160 \times 7

                                                                                    = 1120
