Answer:
Here we know that:
Volume capacity = 150 GB
Free space = 60GB
Here we know that 150 GB represents the 100%, then which percentage represents the 60 GB of free space?
Well, we can write:
60 GB = X
150 GB = 100%
Now we can take the quotient between these two equations:
(60GB/150GB) = X/(100%)
Now we can solve this for X
(60GB/150GB)*(100%) = X = 0.4*100% = 40%

Solve the system of linear equations using either substitution or the elimination method.
y = 3x +5
X+y=1
Answer:
x = -1
y = 2
Step-by-step explanation:
x + y = 1
y = -x + 1
y = -x + 1 (Multiply this by -1)
y = 3x +5
-y = x - 1
y = 3x +5
0 = 4x + 4
4x = -4
x = -1
x + y = 1
-1 + y = 1
y = 2

classify a scalene triangle with one angle
greater than 90°?
A- acute
B - obtuse
C - right
D equilateral
Answer:
The correct answer would be obtuse
Step-by-step explanation:
An obtuse angle is an angle that has a measure of more than 90°
So if a triangle has an angle greater than 90° it would be classified as an obtuse triangle

You have 10 gallons of lemonade to sell. (1 gal $\approx$ 3785 cm3) a. Each customer uses 1 paper cup. The cups are sold in packages of 50. How many packages should you buy? b. How many cups will be left over if you sell 80% of the lemonade?
Answer:
The answer to this question can be defined as follows:
Step-by-step explanation:
Calculating the volume of cone cup:
[tex]= \frac{1}{3}\pi r^2 h \\\\ = \frac{1}{3}\times 3.14 \times 4^2 \times 11 \\\\ = \frac{1}{3}\times 3.14 \times 16 \times 11 \\\\ = \frac{1}{3}\times 3.14 \times 176 \\\\ = 3.14 \times 58.66 \cong 184.31 cm^3[/tex]
[tex]\to 10 \ gal \times 3,785\ \frac{cm^3}{gal} = 37,850\ cm^3\\\\\to 37,850 cm^3 \times \frac{(1 \ cone)}{(184.31 \ cm^3)} \times 205.4 \ cones[/tex]
When buying 5 packages (250 cones):
[tex]\to 8 \ gal \times 3,785 \ \frac{cm^3}{gal} = 30,280\ cm^3 \\\\\to 30,280 \ cm^3 \times \frac{(1\ cone)}{(184.31 \ cm^3)} \cong \ 165 \ cones[/tex]
Calculating the left over cones values:

A.206 cups
B.5 packages
C.85

what is g(x)?
a- g(x)=-x^2
b- g(x)=-lxl
c- g(x)=-2^x
d- g(x)=-x
Answer:
g(x) = -2^x
Step-by-step explanation:
This is an exponential function from the looks of the value for x as it decreases toward the negative value (increase in the absolute value calculation) y is constricted from its vigorous values down to the fractional components of an equation of the standard appearance of y = C^x. For this, try some values. x = 1 y = 2, x = 2 y = 4. There is a trend that is established through these points, and g(x) = -2^x seems to follow this trend as it is reflect across the x-axis. Enter points, it is confirmed and a graphing calculator further substantiates. Try for yourself!

A family buys 6 airline tickets online. The family buys travel insurance that costs
total cost is $1,014. Let x represent the price of one ticket. Write an equation for t
find the price of one ticket.
Answer:
6x + 102 = 1,140
Step-by-step explanation:
We're looking for the sum. The insurance cost 17 dollars per ticket, and there are 6 tickets, so we have to multiply. 17 times 6 is 102. Next, we subtract 102 from both sides. 6x = 1,038. Then, divide by 6. x = 173. So, one ticket costs 173. I don't know if the insurance is included, but if it is, then add 17 and you get 190.

Find the measure of the exterior angle. *
Step-by-step explanation:
✧ [tex] \underline{ \underline{ \large{ \tt{S \: O \: L \: U \: T \: I \: O \: N}}} }: [/tex]
Set up an equation and solve for x :⋆ [tex] \large{ \bf{(4x + 9) \degree = 2x \degree + (3x - 12) \degree}} [/tex] [ Exterior angle is always equal to the sum of two non - adjacent interior angles ]
~Remove the unnecessary brackets
⟶ [tex] \large{ \bf{4x \degree + 9 \degree = 2x \degree + 3x \degree - 12 \degree}}[/tex]
~Add the like terms : 2x ° & 3x°
⟶ [tex] \large{ \bf{4x \degree + 9 \degree = 5x \degree - 12 \degree}}[/tex]
~Move 4x to right hand side and change it's sign
~Similarly move 12 to left hand side and change it's sign
⟶ [tex] \large{ \bf{9 \degree + 12 \degree = 5x \degree - 4x \degree}}[/tex]
⟶ [tex] \large{ \bf{21 \degree = x \degree}}[/tex]
⟶ [tex]{ \large{ \bf{x = 21 \degree}}}[/tex]
Now , Substituting the value of x in (4x+9)° [ Exterior angle ]⤿ [tex] \large{ \bf{4 \times 21 \degree + 9 \degree}} = \boxed{93 \degree}[/tex]

At the local store, the cost of 1 pair of jeans is $24 and the cost of 3 pairs is $24 × 3 = $72. At the online store, the cost of 2 pairs of jeans is ($22 × 2) + $6 = $50 and the cost of 3 pairs is ($22 × 3) + $6 = $72.
Complete question :
Complete the tables to relate the numbers of pairs of jeans to the cost of the jeans at each store. Assume that Tim is placing a single order, and
ignore any taxes.
Answer:
$24, $72
$50
Step-by-step explanation:
From the table :
At local store :
2 pair of jeans cost $48
Cost of a pair :
Cost of 2 pairs / number of pairs
$48 / 2 = $24
Cost of 3 pairs :
Cost per pair * number of pairs :
$24 * 3 = $72
At online store :
Cost of Jean include a fixed fee of $6
Cost of one pair of Jean = $28
Actual cost of Jean :
$28 - $6 = $22
Hence, cost of 2 pair of jeans:
($22*2) + $6
$44 + $6 = $50

She claims that because the mean number of words on each page in the art book is greater than the mean number of words on each page in the science book, the art book has more words per page. Based on the data, is this a valid inference?
Answer:
I think NOT
Step-by-step explanation:
Complete question :
Magdeline wants to know if the number of words on a page in her art book is generally more than the number of words on a page in her science book. She takes a random sample of 25 pages in each book and then calculates the mean, median, and mean absolute deviation for the 25 samples of each book.
Book Mean Median Mean Absolute Deviation
Art 68.7 50 15.4
Science 54.2 55 7.9
She claims that because the mean number of words on each page in the art book is greater than the mean number of words on each page in the science book, the art book has more words per page. Based on the data, is this a valid inference?
Yes, because the mean is larger in the art book
No, because the mean is larger in the art book
Yes, because there is a lot of variability in the art book data
No, because there is a lot of variability in the art book data
Answer:
No, because there is a lot of variability in the art book data
Step-by-step explanation:
Given the data:
Book Mean Median Mean Absolute Deviation
Art __68.7 ___50 ________15.4
Science 54.2 _55 ________7.9
To make our conclusion based on data; Even though te mean number of words in the art book is greater than that of the science book, we may not be able to conclude that the mean number of words on each page of the art book is greater because the mean absolute deviation value which is a measure of the variability of the data is clearly greater for the art book than the science book. With this, we cannot make a valid inference that mean number of words on each page of the art book is greater than the science book.

A rectangle with a length of x + 5 has a perimeter of 4x + 14.
1. Write the expression for the width of the rectangle in terms of x.
2. Suppose the perimeter of the rectangle is 42 inches. What are the length and
width of the rectangle?
3. Write the expression for the area of the rectangle in terms of x.
4. What is the area of the rectangle when x = 7?
Show how t get the answer
Answer:
1. Width = x + 2
2. Length = 12; width = 9
3. x² + 7x + 10
4. 108
Step-by-step explanation:
perimeter = 4x + 14
length = x + 5
1. Perimeter of a rectangle = 2(length + width)
4x + 14 = 2{(x + 5) + width}
4x + 14 = 2x + 10 + 2width
4x + 14 - 2x - 10 = 2width
2x + 4 = 2width
Width = (2x + 4)/2
Width = x + 2
2. Perimeter of a rectangle = 2(length + width)
42 = 2{(x + 5) + (x + 2)}
42 = 2x + 10 + 2x + 4
42 = 4x + 14
42 - 14 = 4x
28 = 4x
x = 28/4
x = 7
length = x + 5
= 7 + 5
= 12
Width = x + 2
= 7 + 2
= 9
3. Area of the rectangle = length × width
= (x + 5)(x + 2)
= x² + 2x + 5x + 10
= x² + 7x + 10
4. Area of the rectangle = x² + 7x + 10
When x = 7
x² + 7x + 10
= 7² + 7(7) + 10
= 49 + 49 + 10
= 108
