12. Which of the following is another way to
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
A population of 1500 bacteria is growing at a rate of 10% each day. What is the domain of the population of growing bacteria?
Answer:
The answer is: the domain of the function that show the population-growing per day is
\mleft{
[tex]x \geqslant 0[/tex]
\mright}
Because the domain is the time, in this cases the days.
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:
[tex]\to 250 - 165 = 85[/tex]
Answer:
A.206 cups
B.5 packages
C.85
Step-by-step explanation:
Clarifiction answer
Also the reason why mine's was 206 because it had no option for 205 but 206 so it saids 206 is the right answer so if you say i'm wrong,it's the online homework's fault and not mines.
ps:You couldn't write the answer,you can only select the answer.

Answer:
Find the side lengths of a triangle
Step-by-step explanation:
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]

A caterer is preparing a dinner for a party. Shecharges an initial fee of $16 and $8.25 per person. How manypeople can attend a dinner that costs $131. 50? Write an equationand solve.
Answer:
The nomber of people can attend a dinner that costs $131. 50 is 14.
Step-by-step explanation:
With the information provided, it can be said that the total cost of a dinner would be equal to the initial fee plus the result of multiplying the price per person for the number of people, which can be expressed as:
c=16+8.25x, where:
c is the total cost of he dinner
x is the number of people
Now, you can replace c with 131.50 that is the cost of a dinner and solve for x to find the number of people that can attend:
131.50=16+8.25x
131.50-16=8.25x
115.50=8.25x
x=115.50/8.25
x=14
According to this, the answer is that the nomber of people can attend a dinner that costs $131.50 is 14.
Need help! Not good at solving math
Answer:
41
Step-by-step explanation:
Erase the line in the middle and it's a right angle, which is 90 degrees, therefore if you subtract 49 from 90 you get 41, the missing angle.

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

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.

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.
