QUESTION POSTED AT 22/02/2020 - 11:31 PM

An earring design is shaped like a triangular pyramid. All the faces are equilateral triangles with side lengths of 14 millimeters. The slant height is 12.1 millimeters. What is the surface area of the earring (pls explain how u got the answer)

In the earring design described above, there are 4 equilateral triangles. The surface area is calculated by solving for the area of a single triangle and multiplying the answer by 4. The area of an equilateral triangle is calculated by the equation,
                                   A = ((√3)/4)s²
Substituting 14 to s and multiplying the answer by 4
                                 SA = √3 x (14 mm)² = 339.48 mm²
Thus, the surface area of the earring is approximately 339.48 mm².

QUESTION POSTED AT 22/02/2020 - 07:05 PM

WORTH 10 POINTS! Mara decides to plot her neighborhood on a coordinate plane. She plots her house at the point (0,0), her school is located at (0,8), the library at (3,8), and the softball field is at (3,0). One day she decides that after school she will run by the library to grab a book, and then head to softball practice and then back home. How far on the coordinate plane does she travel starting at home that morning? Leave your answer in units. A) 11 units B) 14 units C) 19 units D) 22 units

Answer:

Option: D is the correct answer.

D) 22 units.

Step-by-step explanation:

Her home is located at: (0,0)

School at (8,0)

Library at (3,8)

and softball field is located at (3,0) on the coordinate plane.

Now, that morning she starts from home then goes to school then after school she goes to Library and then after library she goes to softball field and returns back home.

Home→ school → Library → Softball field → Home.

This means that she covers the boundary of the rectangle that is formed by the location of the points.

This means in order to find the total distance she traveled we need to find the perimeter of the rectangle.

Length of One side of rectangle(a)= 8 units.

Length of the other side of rectangle(b) = 3 units.

Hence,

Perimeter of rectangle= 2(a+b)

                                    = 2(8+3)

                                   =2×11

                                   = 22 units.

Hence, the total distance she traveled is:

                       22 units.

QUESTION POSTED AT 22/02/2020 - 06:56 PM

There are 200 students in the 8th grade class at Alleghany Middle School. Of these students, 8% play basketball and 14% play soccer. Six students play on both teams. What is the probability that a student plays either basketball or soccer?

Answer:

The probability that a student plays either basketball or soccer is 19% or 0.19.

Step-by-step explanation:

Let A be the event that student play basketball and  B be the event that student play soccer.

P(A)=8\%

P(B)=14\%

It is given that 6 students play on both teams.

P(A\cap B)=\frac{6}{200}\times 100=3\%

We have to find the probability that a student plays either basketball or soccer.

P(A\cup B)=P(A)+P(B)-(A\cap B)

P(A\cup B)=8\%+14\%-3\%

P(A\cup B)=19\%

Therefore the probability that a student plays either basketball or soccer is 19% or 0.19.

QUESTION POSTED AT 22/02/2020 - 06:43 PM

A stone is an English measure of weight. There are 14 lb in 1 stone and 2.2 lb in 1 kg. A certain person weighs 9 stone. If you wanted to convert the person’s weight to kilograms, what conversion factor should you use? Please and thank you.

Here, 14 lb = 1 stone
1 lb = 1/14 stone

2.2 lb = 1 Kg
1 lb = 1/2.2 Kg

Compare both equations, 

1/14 stones = 1/2.2 Kg
1 stone = 14/2.2 Kg
1 stone = 6.36 Kg  [ It's Our Factor ]

Now, person weighs 9 stone would be: 6.36 * 9 = 57.27 Kg

Hope this helps!

QUESTION POSTED AT 22/02/2020 - 06:07 PM

The temperature on a summer afternoon is 84°F. Define a variable and write an expression to find the temperature after it changes. Then evaluate your expression for a decrease of 14 degrees Fahrenheit.

Answer:

x - 84 = - 14

Where, x represent the temperature after it changes.

Step-by-step explanation:

Given,

The temperature before changing = 84° F,

Let x be the new temperature after changing,

Thus, the total changes in the temperature = (x - 84)° F,

According to the question,

The temperature is decreased by 14° F,

x - 84 = - 14

Which is the required expression for finding the temperature after it changes.

QUESTION POSTED AT 22/02/2020 - 06:02 PM

An auction website charges $1 for a bid. The bidding starts at 1¢ and goes up 1¢ at a time. A television that is worth $2000 is won, on average, with a bid of $160. You make one bid at random. Find the expected value of the outcome of the bid. (Write as an exact decimal, with a negative sign, if necessary.)

This is fairly complex, but looks like fun. 
So first lets count how many bids are made till the bidding goes up to 160.
That is 100*160=16000
How much will be your random bid. Each bid has equal chance so it is the avarge of all bids. (1cent + 160dollars)/2 = 80dollars (rounded)
What is your chance of winning: 1 bid wins out of 16000 so 1/16000.
When you win your profit is 2000-80dollars=1920
1920/16000= 0.12 dollars 
You entering the bidding costs 1 dollar and your average win is 0.12
This the outcome is 0.12-1=-0.88 dollars

When jill started jogging she ran 3/4 mile on the first day 1 1/8 miles on the second day and 1 1/2 miles on the third day if she increased the distance she jogged each day by the same amount how far did she jog on the fifth day ? explain how you found your answer

1 1/8 - 3/4 = 
9/8 - 3/4 =
9/8 - 6/8 =
3/8...so she ran 3/8 miles per day

what u have is an arithmetic sequence with a common difference of 3/8.
And we are looking for the fifth term...

an = a1 + d(n - 1)
n = term we want to find = 5
a1 = first term = 3/4
d = common difference = 3/8
now we sub
a(5) = 3/4 + 3/8(5 - 1)
a(5) = 3/4 + 3/8(4)
a(5) = 3/4 + 12/8
a(5) = 6/8 + 12/8
a(5) = 18/8 reduces to 9/4 or 2 1/4 miles <== jogged on 5th day

Sally wants to fill ten 8-inch tea glasses.how much tea does she need

More info is needed.  If you were able to provide the radius of the base of the tea glasses as well as the height (8 inches), then it'd be possible to calculate the volume of one such glass.  Are these short and fat tea glasses?  or tall and slim tea glasses?  My point:  We don't know.  Try to supply the missing info.

There are 10 such 8-inch tea glasses.  Of course you could multiply 10 and 8 to get 80 inches, but 80 inches is NOT a suitable measure of the volume of a liquid.

Which set of numbers can represent the side lengths, in millimeters, of an obtuse triangle? 8, 10, 14 9, 12, 15 10, 14, 17 12, 15, 19

Answer:

8, 10, 14

Step-by-step explanation:

we know that an obtuse triangle has one angle greater than 90°

By using the Pythagoras Theorem, we can test whether these triangles are obtuse or not .

We need to get the sum of the squares of the two shorter sides and compare with the square of the longer side.

For 8, 10, 14

8^{2}+10^{2}

=64+100=164<196 (As (14)^2=196)

Thus, it is an obtuse triangle.

For 9, 12, 15

9^2+12^2

=81+144=225=(15)^2

Thus, it is a right triangle.

For 10, 14, 17

10^2+14^2

=100+196=296>289(As 17^2=289)

Thus, it is An acute triangle.

For 12, 15, 19

12^2+15^2

=144+225=369>361(As 19^2=361)

Thus, it is an acute triangle.

Stan wants to start an IRA that will have $250,000 in it when he retires in 25 years. How much should he invest semiannually in his IRA to do this if the interest is 6% compounded semiannually? Assume an Annuity Due. Round to the nearest cent.

25 years: No Payment, but total is 250000 6 months earlier. Payment of "P". It's value 1/2 year later is P(1+0.03) 6 months earlier. Payment of "P". It's value 1 year later is P(1+0.03)^2 6 months earlier. Payment of "P". It's value 1½ years later is P(1+0.03)^3 6 months earlier. Payment of "P". It's value 2 years later is P(1+0.03)^4 We need to recognize these patterns. Similarly, we can identify the accumulated value of all 50 payments of "P". Starting from the last payment normally is most clear. P(1.03) + P(1.03)^2 + P(1.03)^3 + ... + P(1.03)^50 That needs to make sense. After that, it's an algebra problem. P[(1.03) + (1.03)^2 + (1.03)^3 + ... + (1.03)^50] P1.03−1.03511−1.03=250000
