Answer:
The correct answer will be "0.756596 m²".
Step-by-step explanation:
The given values are:
The radius of an umbrella,
r = 0.4 m
The height of an umbrella,
h = 0.45 m
As we know,
The lateral surface of an umbrella will be:
⇒ [tex]\pi r\sqrt{r^2+h^2}[/tex]
On substituting the values, we get
⇒ [tex]\pi \times 0.4\sqrt{(0.4)^2=(0.45)^2}[/tex]
⇒ [tex]0.756596 \ m^2[/tex]
So that the amount of fabric needed will be "0.756596 m²".
A bag contains 16 cards numbered 1 through 16. A card is randomly chosen from the bag. What is the probability that the card has a multiple of 3 on it?
Answer:
Step-by-step explanation:
Probability is expressed as
Number of favorable outcomes/total number of possible outcomes
From the information given,
Total number of outcomes = 16
Starting from 1, the multiples of 3 between 1 and 16 are 3, 6, 9, 12 and 15
This means that the number of favorable outcomes is 5
Therefore, the probability that the card has a multiple of 3 on it is
5/16 = 0.3125

Answer:
The ratio 1.8 : 2.4 can be rewritten as 3 : 4. We have to solve:
3 : 4 = x : 42
3 * 42 = 4x
x = 3 * 42 / 4 = 31.5

An intelligent trader travels from 1 place to another carrying 3 sacks having
30 coconuts each. No sack can hold more than 30 coconuts. On the way
he passes through 30 checkpoints and on each checkpoint he has to give 1
coconut for each sack he is carrying. How many coconuts are left in the
end? *
Answer:
none
Step-by-step explanation:
the man is carrying 3 sacks
each has 30 coconuts
so at total he has 90 coconuts: 30*3= 90
he passe through 30 checkpoints
ha has to give 1 coconut for each sack
so he gives 3 coconuts each time: 3*1=3
there are 30 ckeckpoints so : 3*30= 90
he has spent all the coconuts unless he has a trick
He starts with 3 sacks with 30 in each sack.
He has to give 1 coconut per sack away. So at first he gives 3 coconuts away.
The first 10 checkpoints he gives away 30 coconuts, so he is left with 2 sacks.
Now he has to give 2 coconuts away. 30/2 = 15, so the next 15 checkpoints he ends up giving away another full sack, so he is left with 1 full sack of 30 coconuts and he has 5 checkpoints left.
Giving away 1 coconut at those checkpoints, he would have 25 left
the density of ethanol is 1.09g/cm^3 the density of propylene is 0.97g/cm^3 80 litres of ethanol are mixed with 148 litres of propylene to make 228 litres of antifreeze work out the density of the antifreeze in g/cm^3
Answer:
The density of the final mixture is 1.012 g/cm³.
Step-by-step explanation:
To calculate the density of the final mixture we need to know the mass of each solution used is. We will also need to convert the volumes from litres to cm³, to do that we can just multiply 1000.
For the ethanol:
[tex]mass = volume*density\\mass = (80*1000)*1.09 = 87,200 \text{ g}\\[/tex]
For the propylene:
[tex]mass = (148*1000)*0.97 = 143,560 \text{ g}[/tex]
So the mass in the final mix is the sum of both:
[tex]mass_{final} = 87200 + 143560 = 230,760 \text{ g}[/tex]
Therefore the density is:
[tex]density_{final} = \frac{230760}{228000} = 1.012 \text{ }\frac{g}{cm^3}[/tex]
The density of the antifreeze is 1.01 g/cm³
Equations are used to show the relationship between two or more numbers and variables.
Let x represent the density of the antifreeze in g/cm^3.
1 cm³ = 0.001 L
80 L = 80000 cm³; 148 L = 148000 cm³, 228 L = 228000 cm³
Hence:
(1.09 * 80000) + (0.97 * 148000) = x * 228000
228000x = 230760
x = 1.01 g/cm³
The density of the antifreeze is 1.01 g/cm³

Answer:
10/16 but I’m pretty sure your teacher is gonna want for you to reduce to where you answer would actually be 5/8
Step-by-step explanation:
1/16 +9/16 you’ll add the top number which equals up to 10, but since both of your bottom number are the same you lol keep those making your answer 10/16. But most teacher prefer you to reduce so it’ll bring your answer to 5/8 since the only number that can go into both 10 and 16 is 2 which is what you did. In conclusion 5/8 is your answer.
the mass of the earth is 1/95 of the mass of the planet Saturn. the mass of the earth is 5.97×10^24 kilograms. calculate the mass of the planet Saturn, giving your answer in standard form, correct to 2 significant figures
Answer:
5.8 * 10^26 kg
Step-by-step explanation:
If the mass of the earth is 1/95 of that if saturn, this means that the mass of saturn is 95 times that of earth
From the question we were given the mass of the earth as 5.97 * 10^24
The mass of saturn is thus 95 * 5.97 * 10^24 =
576.15 * 10^24
This is 5.8 * 10^26 kg

A bike store marks up the wholesale cost of all bikes they sell by 30%. Calvin wants to buy a bike that has a price tag of $125. What was the wholesale cost of this bike?
Answer:
96.15
Step-by-step explanation:
The mark the bikes up 30 %
wholesale + wholesale * 30 percent = selling price
wholesale ( 1+ 30%) = selling price
wholesale (1.30) = 125
Divide by 1.30
wholesale = 125/1.30
wholesale =96.15384615

a man is four times as old as his son in five years time he will be three times as old as his son what is the present age of the son in years
I would start by setting up a chart like I did below.
Label one column age now and the other age in 5 years.
Since we don't know the son's age we use x.
We do know that the man's age is 4 times the son's age.
So the man's age will be 4x.
In the age in 5 year column, we add 5 to their current ages.
Now set up our equation.
Since it says "in five years" we use information in second column.
In 5 years time, he, "4x + 5", will be, equals,
3 times as old as his son, "3(x + 5)".
So we have 4x + 5 = 3(x + 5).
Solving from here, we find that x = 10.
So the son is 10 and the man is 4 times his age or 40.

Answer:
Step-by-step explanation:
8•6= 48•5=240 divided by 3= 80
The volume of the rectangular pyramid is 80 cubic centimeter.
What is volume?
Volume is the measure of the capacity that an object holds.
Formula for the volume of a rectangular pyramid[tex]v = \frac{lwh}{3}[/tex]
Where,
V is the volume of the rectangular pyramid
l is the base length
w is the base width
h is the Pyramid height
According to the given question
We have
Base length of the rectangular pyramid = 8cm
Base width of the rectangular pyramid = 6cm
And the height of the rectangular pyramid = 5cm
Therefore,
The volume of the rectangular pyramid is given by
V = [tex]\frac{(8)(6)(5)}{3}[/tex]
⇒ V = 8 × 2 × 5
⇒ V = 30 cubic centimeter
Hence, the volume of the rectangular pyramid is 80 cubic centimeter.

Lincoln is measuring the angles of quadrilateral WXYZ to determine whether it is congruent to the quadrilateral below.
Quadrilateral R S T Q. Angle R is 140 degrees, angle S is 94 degrees, angle T is 79 degrees, and angle Q is 47 degrees.
Which pair of measurements are possible if they are congruent figures?
Measure of angle W = 47 degrees and Measure of angle X = 94 degrees
Measure of angle X = 94 degrees and Measure of angle Z = 79 degrees
Measure of angle W = 47 degrees and Measure of angle Y = 140 degrees
Measure of angle X = 140 degrees and Measure of angle = 94 degrees
Answer:
None of these
Step-by-step explanation:
The congruent occurs when the two diagrams are matched with each other in terms of the same sides and same angles
In other terms, we can say that if both quadrilaterals contain the same sides and same angles so we called as congruent
As we can see in the figure that there is only angles are given but not the sides that are totally different
Hence, none of these is the right answer
Answer:
D.) Measure of angle X = 140 degrees and Measure of angle = 94 degrees

A vertical translation is used to move triangle DEH onto triangle D’E’H’.
Use the drop-down menus to describe the vertical translation used.
Answer this:
•vertical translation: Triangle DEH is translated —— units ——.
Answer:
5 units in the positive y-axis
Step-by-step explanation:
In order to get triangle D’E’H’, triangle DEH was moved upwards for a number of units which can be obtained by taking a corner of the rectangle and counting the number of square spaces (grids) it was moved upwards by.
Step one: Pick a corner of the triangle.
For this, we can pick corner D and note its position on the graph
Step two: Count the number of squares between point D and D'.
Once we count this, we can see that there are 5 square spaces between D and D'.
Step Three: Repeat the process for the other two corners of the rectangle.
If the square spaces counted are the same with what was obtained for the first corner, we can comfortably say that the rectangle was translated upwards by a distance of 5 units
