A vase in the shape of a cylinder has a radius of 4.3 centimeters and a volume of 1330.2 cubic centimeters, as
shown in the diagram.
What is the height of the vase in centimeters? Round your answer to the nearest tenth.

Answers

Answer:

h = 22.91 cm

Step-by-step explanation:

Given that,

The volume of a vase, A = 1330.2 cm³

Radius of the vase, r = 4.3 cm

We need to find the height of the vase. The formula for the volume of a cylinder is given by :

[tex]V=\pi r^2 h\\\\h=\dfrac{V}{\pi r^2}\\\\h=\dfrac{1330.2 }{3.14\times (4.3)^2}\\\\h=22.91\ cm[/tex]

or

h = 23 cm

So, the height of the vase is equal to 23 cm.

Are the pink arcs congruent?

Answers

Answer:

Yes, they are congruent.

Step-by-step explanation:

Supplementary angles equal up to 180°.

70+40 = 110

180 - 110 = 70.

Angle BAE is 70°.

And, angle ADC is 70° as well.

Therefore, the pink arcs are congruent.

how do i get the answer and what is the answer? im looking for a right answer not just someone who types in the mayo mayo

Answers

Answer:

x = 51°

Step-by-step explanation:

The straight line segment has a total angle of 180°. Therefore, to find the angle inside the triangle that is next to 94°, subtract 94 from 180:

180° - 94° = 86°

That angle is almost a right angle but not quite. Now, to find x, add up the two angles inside the triangle and subtract it from 180°:

43° + 86° = 129°

180° - 129° = 51°

I’m having trouble understanding this, if anyone could help me understand it I’d greatly appreciate it.

Mr. Strand mowed 2 5 of his lawn. His son mowed 1 3 of it. Who mowed most of the lawn? How much of the lawn still needs to be mowed?

Answers

Answer:4/15 of the portion of land is left to be mowed.

Step-by-step explanation:

Portion of Lawn mowed by Mr Strand =2/5

Changing to decimal we have 0.4

Portion of Lawn mowed by his son=1/3

Changing to decimal, we have 0.333

From this , we can deduce that Mr Strand mowed most of the Lawn.

Now to find the portion of Lawn remaining to be mowed

Let total portion be =1whole

Such that portion left to be mowed

=1-(2/5+1/3)

1- 6 + 5/15

1-11/15

15/15 -11/15

4/15 of the portion of land is left to be mowed.

Answers

first you do 6 x 6 = 36 to get the area

then you divide 36 by 2 because the shape is a triangle (most of the time a triangle is half a square)

so the answer is: 18 square feet

Answer:

137 square feet

Step-by-step explanation:

To find the area of this figure, you will need to combine the area of the triangle and the rectangle. The area formula of a triangle is A = 1/2lw (l = length, w = width). You just find the area the same way you would the rectangle and the divide it by 2. 6 times 3 is 18, and 18 divided by 2 is 9. The area of the triangle is 9 square feet. To find the area of the rectangle, multiply the length and the width (16 and 8). The product is 128. 128 + 9 = 137.

The Monday after Thanksgiving is called Cyber Monday. Amazon is
offering deals on many popular items. The same drone helicopter
is normally sold for $179.99, but on Cyber Monday, Amazon will be
selling it for $125.99. What is the percent change on the drone. Round to the nearest percent

Answers

Answer:

the percentage change on the drone is 42.86%

Step-by-step explanation:

The computation of the percentage change is shown below:

Since the helicopter was sold for $179.99

But amazon would be selling it for $125.99

So, the percentage change would be

= (Sale value -  sale value by amazon) ÷ ( sale value by amazon) × 100

= ($179.99 - $125.99) ÷ ($125.99) × 100

= 42.86%

Hence, the percentage change on the drone is 42.86%

A café has a monthly fixed cost of $4700, and a typical customer order costs the café $2. Therefore, the cost to serve x customers in a month is given by x = 4,700 + 2x. The typical order costs $10. So revenue is y = 10x. Find the number of customers that would need to come in the café for the company to break even. (Intersection point)

Answers

Answer:

The number of customers that would need to come in the café for the company to break even is 470.

Step-by-step explanation:

Given

Revenue = y = 10x ……………….…. (1)

Cost = x = 4,700 + 2x ……………… (2)

Since the company will break even when Revenue is equal to Cost, we therefore equate equations (1) and (2) and then solve for x as follows:

10x = 4,700 + 2x

10x - 2x = 4,700

x = 4,700 / 10

x = 470

Therefore, the number of customers that would need to come in the café for the company to break even is 470.

area circle = πr²   or  π(d/2)²  but how to find the diameter?

The only angles I can see to calculate is in the small right triangle

The smaller angle on the right is ...

        sin Ф = opp/hyp = 6/10    Ф = 36.87°

This angle is the same as the small angle on the LARGE right triangle

So now I want to calculate the side (diameter) opposite the smaller angle

      sin Ф = opp/hyp = diameter/300 = sin 36.87°    

                  diameter = 300 sin 36.87°

                                  = 300 (6/10)

                                  = 180 ft

         

area circle = πr²   or  π(d/2)²

area circle =  π(180/2)²

area circle = 25446 ft²  which is close to answer A  25434 ft²

There is actual no need to find the sin Ф wasted step      

just use 6/10  small triangle     is similar to diameter/300   the large triangle

  opp / hyp small  6/10  = diameter/300    diameter = 180

  area circle =  π(180/2)²  = 25446

there are 45 students In a class. if 60% of them are girls. find the numbers of girls and boys​

Answers

Step-by-step explanation:

No. of students in class = 45 .

Percentage of girls = 60% .

No . of girls = 45 × 60/100 = 45 × 3/5 = 18 .

No. of boys = 45 - 18 = 27

Answer:

27 girls

18 boys

Step-by-step explanation:

Convert 60% to a decimal.

60% · .01 =  0.6

Multiply 45 students by 0.6 to find the number of girls in the class.

45 * 0.6 = 27 girls

Subtract this amount from the total number of students in the class.

45 - 27 = 18 boys

There are 27 girls and 18 boys in the class.

Desmond really like Legos. Last Saturday Desmond counted his Legos and realized that

he has 65 altogether! Desmond has 7 less green Legos than red Legos, and the amount of

blue Legos he has is two more than three times his red Legos. How many of each color

Lego does Desmond have?
Answer Quick.
Only reply if you have the answer please

Answers

Answer: 14 red, 7 green, 44 blue

Step-by-step explanation:

First, use the letter r as a variable to represent the number of red Legos. The number of green Legos (g) is 7 less than the number of red Legos, or g = r-7. The number of blue Legos (b) is 2 more than 3 times the number of red Legos, or b = 3r+2. The total number of Legos is the number of red + green + blue Legos, which can be represented as 65 = r+g+b.

Substitute the equations for g and b in. This should give you a final equation of 65 = r+(r-7)+(3r+2). To solve for the number of red Legos, first add up all of the terms to get 65 = 5r-5. Now add 5 to each side (70 = 5r). Finally, divide each side by 5 (r = 14).

To find the number of green Legos, substitute the number of red Legos (14) into the equation for the green Legos (g = r-7). This should get you the equation g = 14-7 which simplifies to g = 7.

To find the number of blue Legos, substitute the number of red Legos (14) into the equation for the blue Legos (b = 3r+2). This gives you the equation b = (3*14)+2. First, multiply 3 and 14 to get b = 42+2. Finally, add them together to get b = 44.
