Answer:

A and C are correct, but not B

Step-by-step explanation:

When you round, you only look at the number behind the place you are rounding.

6.04 doesn't round to 6.1, so that is not correct

Answer:

Just A and C

Step-by-step explanation:

B doesn't count because you would not be looking at the 9. Only the 4.

You only look at one number to the right.

What is the midpoint of a segment in the complex plane with endpoints at 6 -2i and -4 + 6i

alexdok [17]

Answer:

Midpoint of a segment in the complex plane with endpoints at 6 -2i and -4 + 6i is:

1+2i

Step-by-step explanation:

The midpoint of a segment in the complex plane with endpoints at 6 -2i and -4 + 6i is:

$\dfrac{6-2i-4+6i}{2} \\\\=\dfrac{2+4i}{2}\\ \\=1+2i$

Hence, midpoint of a segment in the complex plane with endpoints at 6 -2i and -4 + 6i is:

1+2i

Addison is making Caramel apples. She has 2 1/2 bags of apples. One bag has 8 apples, and each apple weighs 5 ounces

andrey2020 [161]

Answer:

The expression that can be used is :

Number of bags x Number of apples in a bag x Weight of 1 apple

The total weight of apples in 2 1/2 bags of apples = 100 ounces.

Step-by-step explanation:

The given question is INCOMPLETE.

Addison is making caramel apples. She has 2 1/2 bags of apples. One full bag has 8 apples, and each apple weighs 5 ounces. Write an expression that could be used to find the total number of ounces of apples Addison has. Then find the total number of ounces.

Now, here the weight of 1 apple = 5 ounces

1 bag = 8 apples

⇒ Weight of 8 apples = 8 x ( weight of 1 apple) = 8 x (5 oz) = 40 oz

⇒ Total weight of 1 bag of apples = 40 oz

Now, the total bags of Apples Addison has = 2 1/2 bag

= 2 + 1/2 bag = 2. 5 bag

So, the weight of apples in 2.5 such bags = 2.5 x ( Weight in 1 bag)

= 2.5 ( 40 oz) = 100 oz

Hence, the total weight of apples in 2 1/2 bag = 100 ounces.

The expression that can be used

= Number of bags x Number of apples in a bag x Weight of 1 apple

= 2 1/2 x 8 x (5 oz)

PLEASE HELP DUE TODAY DO A AND B PARTS PLEASE PLEASE HELP ME FIGURE OUT THE LENGTH 100 POINTS

aksik [14]

Answer:

Length A: 5 ft

Width B: 4 ft

volume = 88 ft³

Step-by-step explanation:

Length A: 8 - 3 = 5 ft

Width B: 8 - 4 = 4 ft

<u>Volume</u>

The easiest way to calculate the volume is to split the trough into two rectangular prisms. (imagine drawing a horizontal line from the internal corner of A and 4ft to the left 8ft side).

Volume of a rectangular prism = width x length x height

Volume of rectangular prism 1: B x 8 x 2 = 4 x 8 x 2 = 64 ft³

Volume of rectangular prism 2: 3 x 4 x 2 = 24 ft³

Total volume = 64 + 24 = 88 ft³

The ratio of sixth grades to seventh grades in the club of science club is 4:7. If there are 20 sixth grades in the club, how ma

Vika [28.1K]

Answer: 35 seventh graders

Step-by-step explanation:

The simplified ratio is 4:7 sixth graders to seventh graders

The number of sixth-graders is 5 times the number shown in the ratio of attendees (20/4 = 5). Thus, the number of 7th graders must also be 5 times greater than the simplified ratio.

7*5 = 35, thus there are 35 seventh graders in the club

There is an average of 3.5 x 10^−2 kilograms of dissolved salt in each liter of seawater. The South China Sea contains approxima

Fiesta28 [93]

Alright, since there's 3.5*10^(-2) of salt for each liter of seawater, that means that for each liter added we add that to it, meaning that we multiply the amount of salt per liter by the total amount of liters, resulting in 3.5*9.88*10^(-2)*10^18=34.58*10^16 (by adding -2 and 18 we get 16). Since we only want 1 number in front of the decimal (that's not a 0) for scientific notation, we can move the decimal one spot to the left to make it 3.458. However, we can't simply move the decimal without changing the exponent - since we moved it one to the left, we must increase the power from 16 to 17 (conversely, if it moved to the right, we'd decrease the power), resulting in 3.458*10^17
