What is this answer

Kaylee has a $20 gift card to spend at an online entertainment store. The table shows the categories of items she can buy. Kayle

aalyn [17]

Answer:

see the attached

Step-by-step explanation:

The total cost of Kaylee's purchases will be the sum of products of the number bought and the cost of the item bought. She wants this total to be at most $20. In math terms, where x and y represent songs and TV episodes, the inequalities describing the scenario are ...

1.29x +2.99y ≤ 20
x ≥ 0
y ≥ 4

The attached graph shows a plot of this set of inequalities with the feasible region shaded red. The combinations of songs and TV episodes Kaylee can afford are shown by the coordinates of the red dots in the feasible region.

According to the "special," if Kaylee buys 6 songs (and 4 TV episodes), she will get a 7th song free. That is, the "special" means point (6, 4) becomes (7, 4) if there is a 7th song that Kaylee wants.

Each cone of the hourglass has a height of 18 millimeters . the total height of the sand within the top portion of the hour glas

statuscvo [17]

Let

Vco------------------- >Volume cone
Vcy------------------ >Volume cylinder
r= 8mm
hco----------- > height of cone=18 mm
hcy------------ > height of cylinder =54-18=36 mm

then

Vco=π*r² *hco/3--------- > π*8² *18/3=π*384 mm³
Vcy=π*r² *hcy--------- > π*8² *36=π*2304 mm³

the total cubic millimeters of sand=Vco+Vcy=π*384+π*2304=π*2688

if 10π cubic millimeters --------------------- > 1 seg
π*2688--------------------------------- X

X=π*2688/10π=268.8 seg

the answer is 268.8 seg

a man deposits 45 into an account the next day he makes 3 deposits of 20 $ each a week later he withdraws 105$

zheka24 [161]

Answer:

The amount available in account at last is $0

Step-by-step explanation:

Given as :

The withdrawal amount from the account at the end = $105

The first deposit amount = $45

The next three deposit amount = $20 each

I.e The second deposit amount = 3 × $20

Or, The second deposit amount = $60

Let The amount available in account at last = $A

<u>Now, According to question</u>

The amount available in account at last = (first deposit amount + second deposit amount) - withdrawal amount from the account at the end

i.e A = ($45 + $60) - $105

Or, A = $105 - $105

∴ A = $0

So, The amount available in account at last = A = $0

Hence, The amount available in account at last is $0 . Answer

X + 1 and 1/4 = -5/8

slavikrds [6]

X + 1 = - 1/4 - 5/8
x + 1 = -2 - 5 / 8
x + 1 = - 7/ 8
x = -7 /8 - 1
x = - 7 - 8 / 8
x = - 15 / 8

What is an advantage of using the range as a measure of variation

Anit [1.1K]

Answer:

The range is the difference between the largest and the smallest observation in the data. The prime advantage of this measure of dispersion is that it is easy to calculate. On the other hand, it has lot of disadvantages. It is very sensitive to outliers and does not use all the observations in a data set.
