Answer:

374,463,000

Step-by-step explanation:

374,462,894

Identify the thousands spot and locate the digit next to it.

374,462,894

If the number is greater than or equal to 5, we round up. If the number is less than or equal to 4, we round down.

8 is greater than or equal to 5. We round up.

374,462,894 ≈ 374,463,000

Hope this helps.

Answer:

[See Below]

Step-by-step explanation:

✦ The number in the thousandth place is $2$ .

✧ To round, look at the number to the right, in this case it's $8$ .

○ If the number is greater than or equal to $5$ , then round up.

○ If the number is less than $5$ , round down.

✦ So then we would change the $2$ to a $3$ .

✦ Then rewrite the number:

✧ $374463000$

6×10^-3

Step-by-step explanation:

0.006

Move the point to the front of the first number that is from 1 to 9.

In the question it's 6, so you move it to the front of 6 .

And because it's from back to front it has to have a negative sign in its power

which is going to be

6× 10^-3

where 6=the number from 1 to 9

^ means raise to power or power of

-3= the negative power

A beekeeper has 65,000 female bees and 700 male bees in one colony. A disease kills % of the female bees and % of the male bees.

Paha777 [63]

Complete Question

A beekeeper has 65,000 female bees and 700 male bees in one colony. A disease kills 25% of the female bees and 14% of the male bees. After the disease hits the colony, the beekeeper decides to sell LaTeX: \frac{1}{2} 1 /2 of the remaining female bees to a friend.

How many total bees are left in the beekeeper’s colony after the disease and sale?

Answer:

24977 bees

Step-by-step explanation:

From the above question:

Number of female bees = 65,000

Number of male bees = 700

A disease kills 25% of the female bees and 14% of the male bees.

Number of female bees killed = 25% × 65,000

= 16,250 bees

Amount of female bees left = 65,000 - 16,250

= 48750 bees

Number of male bees killed = 14% × 700

= 98

Amount of male bees left = 700 - 98

= 602 bees

After the disease hits the colony, the beekeeper decides to sell LaTeX: \frac{1}{2} 1 /2 of the remaining female bees to a friend.

Hence:

1/2 × 48750 bees

= 24375 bees

Total bees are left in the beekeeper’s colony after the disease and sale is calculated as:

24375 female bees + 602 male bees

= 24977 bees

A rectangle is 4.2 centimetres wide and each diagonal is 8.6 centimetres long. What is the measure of the angle between a diagon

CaHeK987 [17]

Answer:

$60.8^\circ$

Step-by-step explanation:

First, let's check side lengths.

Using the Pythagorean theorem we can find the length of the other side of the rectangle.

a^2 + b^2 = c^2

4.2^2 + b^2 = 8.6^2

b^2 = 56.32

b = 7.5

The other side of the rectangle measures 7.5 cm, so now we know that 4.2 cm is indeed the shorter side of the rectangle.

For the angle in question, the 4.2 cm side is the adjacent leg.

The diagonal of 8.6 cm is the hypotenuse.

The trig ratio that relates the adjacent leg to the hypotenuse is the cosine.

$\cos \alpha = \dfrac{adj}{hyp}$

$\cos \alpha = \dfrac{4.2~cm}{8.6~cm}$

$\alpha = \cos^{-1} \dfrac{4.2~cm}{8.6~cm}$

$\alpha = 60.8^\circ$
