Answer: Round up or down.

Step-by-step explanation: When you round up, look at the number to the right of the number you wanna round. If it’s less than 5, you round down, if it’s more than 5, you round up. On a number line, for ex. Let’s say you wanna round 550 to hundreds, 600 or 500, 600 would be the answer because 550 is more closer to 600 by default.

What are the roots of the equation?

alexandr1967 [171]

Answer:

The answer is 2. x = 2

Step-by-step explanation:

2 x 2 + 1x = 6

2 x 2= 4

4 + 1x = 6

4 - 4 = 0

6 - 4 = 2

1x = 2

1x / 1 = 1 <--- This gets cancled out but leave the x.

2/ 1 = 2

x = 2

Toms garden is 8 acres. Two fifths is corn. Of that, three tenths is early corn and one tenth is late corn. How many acres of ea

Charra [1.4K]

Answer:

He have <u>0.96 acres</u> of early corn.

Step-by-step explanation:

Given:

Toms garden is 8 acres. Two fifths is corn.

Of that, three tenths is early corn and one tenth is late corn.

Now, to find the acres of early corn.

Total garden = 8 acres.

Total Corn in garden = $\frac{2}{5}\ of\ 8=\frac{2}{5} \times 8=\frac{16}{5}$ acres.

<em>As, given of the total corn in garden, three tenths is early corn.</em>

Now, to get the early corn he have:

= $\frac{3}{10} of \frac{16}{5}$

= $\frac{3}{10} \times \frac{16}{5}$

= $\frac{48}{50}$

= $0.96\ acres.$

Therefore, he have 0.96 acres of early corn.

Help pleaseeee ??????!!!!! I choosed the Death Valley one

disa [49]

1.) C(t) = -0.30(t - 12)^2 + 40
for t = 12: C(12) = -0.30(12 - 12)^2 + 40 = -0.30(0)^2 + 40 = 40°C
For t = 24: C(24) = -0.30(24 - 12)^2 + 40 = -0.30(24 - 12)^2 + 40 = -0.30(12)^2 + 40 = -0.30(144) + 40 = -43.2 + 40 = -3.2°C

4.) F(t) = 9/5 C(t) + 32
for C(t) = 40°C: 9/5 (40) + 32 = 72 + 32 = 104°F
for C(t) = -3.2°C: 9/5(-3.2) + 32 = -5.76 + 32 = 26.24°F

5.) F(t) = 9/5 C(t) + 32 = 9/5 (-0.30(t - 12)^2 + 40) + 32 = -0.54(t - 12)^2 + 72 + 32 = -0.54(t - 12)^2 + 104

The area of a square photo is 9 square inches how long is each side of the photo

Marta_Voda [28]

Let the side of each side of photo is a inch.

So area of photo = (side)^2 = $a^2$

But as given area of photo is 9 square inch.

So $a^2 = 9$

$a = \sqrt{9}$
$= 3$

So side of photo is 3 inch.
