Answer 1

Answer:

Radius = 2.5559cm

To the nearest tenth = 3cm

Step-by-step explanation:

Volume of bottle = 160cm³

Height of bottle = 7.8cm

π = 3.14

Radius of bottle = r

Using the formula,

V = πr²h

160 = (3.14)(r)²(7.8)

160= 24.492r²

Dividing both sides by 24.492,

160/24.492 = r²

r² = 6.5327, which is approximately 6.533

Making r the subject,

r = √6.533

r = 2.5559, which is approximately 2.556

Round to the nearest tenth = 3

Therefore, the radius of the cylindrical bottle is 3cm.

Hope it helps. Happy New Month. Have a nice week.

c. { (9 - 3)^2 + 8} ÷ 11 =

Answers

Answer:

= 4

Step-by-step explanation:

First, we need to simplify the expression inside the parentheses:

(9 - 3) = 6

Next, we square 6:

6^2 = 36

Now we add 8 to 36:

36 + 8 = 44

So now our expression looks like this:

(44) ÷ 11

Finally, we divide 44 by 11:

44 ÷ 11 = 4

Therefore, the final answer is:

4

Answer: 44

Step-by-step explanation:

Subtract 3 from 9 to get 6.

6²+8/1

Calculate 6 to the power of 2 and get 36.

36+8/1

Anything divided by one gives itself.

36+8

Add 36 and 8 to get 44.

Answer:

B. 8=2+2a and 3=a

Step-by-step explanation:

1. Look at the scale. On the left side we have 8, on the right side we have 2a + 2.

The two balance each other out perfectly, therefore they're equal.

2. We write our equation.

8=2a+2

3. we substract 2 from the right side so only the '2a' will be left. but if we do something to the right side, we do the same to the left. So, -2 from both sides.

8=2a+2 /-2

6=2a

4. Now we know that 2a=6, but we need to know much much one 'a' is, so we divide by 2.→ divide both sides by 2, so only the 'a' is left on one side, and only a number on the other.

6=2a. /÷2

3=a → this is your answer.

Answers

How to Compare Data Sets?

Common graphical displays (e.g., dotplots, boxplots, stemplots, bar charts) can be effective tools for comparing data from two or more data sets.

Four Ways to Describe Data Sets:

When you compare two or more data sets, focus on four features:

   Center. Graphically, the center of a distribution is the point where about half of the observations are on either side.

   Spread. The spread of a distribution refers to the variability of the data. If the observations cover a wide range, the spread is larger. If the observations are clustered around a single value, the spread is smaller.

   Shape. The shape of a distribution is described by symmetry, skewness, number of peaks, etc.

   Unusual features. Unusual features refer to gaps (areas of the distribution where there are no observations) and outliers.

The remainder of this lesson shows how to use various graphs to compare data sets in terms of center, spread, shape, and unusual features.

Lily has to go to Antarctica for a science school field trip. A ticket to Antarctica costs $4,689. Supplies for the trip cost $9,000. She has $20,000. How much will she have left over?

Answers

To calculate how much Lily will have left over after buying the ticket and supplies, we need to subtract the total cost of the ticket and supplies from the amount of money she has.

Total cost of ticket and supplies: $4,689 + $9,000 = $13,689

Amount left over: $20,000 - $13,689 = $6,311

Therefore, Lily will have $6,311 left over after buying the ticket and supplies for her trip to Antarctica.
She will have $15,689 left

A roll of 40 quarters weighs 8 ounces. Which proportion can be used to find the weight in ounces, w, of 200 quarters?

A. 40/8 = 200/w
B. 40/w = 8/200
C. 40/200 = w/8
D. 40/8+w = w/200

Answers

Answer:

The answer is A. 40/8=200/w

Step-by-step explanation:

This works because the corresponding proportions are in the same place in each fraction. 40 is the number of quarters and it is the numerator. 200 is also the number of quarters and is the numerator. The same goes for 8 and w being the denominators.

If you were to finish solving the problem, you'd get w=40.

It's d 40/8 +W = W/200

20 pts!! Find the total surface area of this prism.



___ square meters

Answers

Answer:

38m^2

Step-by-step explanation:

We are solving the surface area of a rectangular prism that has been cut in half diagonally.

Our equation for this is
S = 2(lw + lh + wh)
Plug in our info
S = 2(10(1.5) + 10(2) + 1.5(2))
Work inside parentheses
S = 2(15 + 20 + 3)
S = 2(38)
S = 76
Our original surface area would be 76 if this were a regular rectangular prism, but its not! It's cut in half.
So, 76/2 is 38.

Answers

Answer:

1. 158 degrees

2. 36 degrees

3. 150 degrees

4. 80 degrees

Step-by-step explanation:

1. angle x and the given angle are supplementary angles because they add up to form a straight line. This means the two angle measures add up to 180 degrees, so angle x + 22 = 180, and angle x = 180 - 22 = 158 degrees

2. angle x and the given angle are supplementary angles so angle x = 180 - 144 = 36 degrees

3. angle x and the given angle are supplementary angles, so angle x = 180 - 30 = 150 degrees.

4. angle a is just the sum of the two angles: a = 30 + 50 = 80 degrees

Answer and Step-by-step explanation:

For the first question (#4) we can simply add the two angles together:

50+30=80

For the second picture (#3) we can see that the angles are adjacent, and therefore add up to 180 degrees. Since we know that, we can subtract 30 from 180 to find x:

180-30=150

We can use the same rule for the third picture (#1), and subtract 22 from 180:

180-22=158

And one last time, we can subtract 144 from 180 for the fourth picture (#2) since they are also adjacent:

180-144=36

Step-by-step explanation:

y represents the total cost while x represents the quantity so x would be multiplied by the original cost of 1 to find the total cost/y.

Answer:

y=1.05x

Step-by-step explanation:

The equation that represents the total cost, y, of x yogurts at the store is:

y = 1.05x

This is because the cost of one yogurt is $1.05, and the total cost of x yogurts is equal to the cost of one yogurt multiplied by the number of yogurts purchased, which can be expressed as:

y = $1.05x

Therefore, the equation that represents the total cost, y, of x yogurts at the store is y = 1.05x.

Step-by-step explanation:

the area for a triangle is 1/2(b×h), and there are q triangles here, so just do b×h

y×h = 24×16 = 384

next, find the area of the bottom and sides of the prism.

x×z = 20×9 = 180

180 × 2 = 360

z×y = 9×24 = 216

finally, add all of those together

384+360+216 = 960 units²

The answer is B or 960 units
