Lin got a $50 gift card to an online music store. She uses the gift card to buy an album for $9.99. She also wants to use the gift card to buy some songs. Each song costs $1.29.
Which of these inequalities describes the situation, where n is the number of songs Lin wants to buy.
9.99+1.29n greater and equal to 50
9.99+1.29 less than and equal to 50
9.99-1.29n less than or equal to 50
9.99-1.29n greater than or equal to 50
Answer:
b) 9.99 + 1.29n ≤ 50
Step-by-step explanation:
I think, this question is incomplete., may be there is typo. To complete the question, it's suppose to be like this
a)9.99 + 1.29n ≥ 50
b)9.99 + 1.29n ≤ 50
c)9.99 − 1.29n ≤ 50
d)9.99 − 1.29 n ≥ 50
well, we have to figure out the information given
price of the album: $9.99
each song cost : $1.29
gift card: $50
number of songs : n
The answer is b) 9.99 + 1.29n ≤ 50 , because the sum of the price of the album ($9.99) and the songs ($1.29 n) must be less or equal to the value of the gift card ($50). Fore sure it 's correct.....
Determine which of the two acute angles has a sine of 5/11 (click photo)
Answer:
A
Step-by-step explanation:
sin: [tex]\frac{opposite}{hypotenuse}[/tex]
sin: [tex]\frac{CB}{AC}[/tex] = [tex]\frac{5}{11}[/tex]
For triangle ABC, sin(A) = 5/11
What is acute angle?"If the angle measure less than 90° then it is an acute angle."
What is sine theta?For a right triangle,
sin(theta) = opposite side/hypotenuse
where theta is an acute angle.
For given example,
we have been given a right triangle ΔABC
Since ∠B = 90°, ∠A and ∠C must be an acute angles.
⇒ sin(A) = BC/AC
⇒ sin(A) = 5/11
and sin (C) = AB/AC
⇒ sin(C) = (4√6)/11
Therefore, sin(A) = 5/11

CAN SOMEONE HELP ME UNDERSTAND THIS PLEASE
YEAH OFC SHAWTY!
so for A its -4^11 because if the powers have the same base and they are being multiplied you add the powersFor B its the same idea, they have the same base, and are being multiplied so you add the powers- 13^9For C its similar, you have the same base, but since its Dividing, you subtract the powers. So, 9^5for D you pretend like the denominator has a power of 1 and subtract. So its -24^5-24^1 which hopefully puts it into perspective of being -24^4 becuase we subtracted the powersI cant do 2 right now, but i will in a minute
And for 3 his mistake is that they arent the same bases so he cant add the powers, he should have converted them to the same base first.
A linear function that represents the number of animals adopted from the shelter is compared to a different linear function that represents the hours volunteers work at the shelter each week. Describe the key features of the functions that are needed to determine if these lines intersect.
Step-by-step explanation:
Step-by-step explanation:
Given the table:
Month f(x) = Number of imports g(x) = Number of exports
January (1) 3 1
February (2) 4 3
March (3) 5 5
April (4) 6 7
From the table, it is clear that:
Number of imports = number of month + 2
so
also
Number of exports = 2(number of month) + 1
so
Therefore, the number of imports equals the number of months plus one. i.e., which is a linear function.
If we compare it with the slope-intercept form of the line
Then,
slope = m = 1
y-intercept = 2
Also number of exports equals is also a linear function.
i.e.
Here,
slope = m = 2
y-intercept = -1
If there is some point that is equal in both the function then it can be said that they are intersecting.

find the area of the shade sector of the circle
Step-by-step explanation:
We need to find the area of the shaded region. We see that the region next to that has a central angle of 120°. Also we know that angle in a straight line is 180° . So the measure of central angle of that shaded region will be 180° - 120° = 60° . Now we can use the formula of area of sector to find out the area of the shaded region.
[tex]\tt\to Area = \dfrac{\Theta}{360^o}\times \pi r^2 \\\\\tt\to Area = \dfrac{60^o}{360^o}\times \pi (8cm)^2 \\\\\tt\to Area =\dfrac{\pi \times 64}{6}cm^2\\\\\to\boxed{\orange{\tt Area_{(Shaded)}= 10.66\pi cm^2}}[/tex]
It would take ___ hours to drive 240 miles from Boston to New York, if one drives at a constant speed of 40 mph.
Answer:

Christopher sold his dinette set for $245 through an online site, which charged him 9% of the selling price as commission. what is the commission?
Answer:
$22.05
Step-by-step explanation:
If a product has a sales commission, then one must divide the commission percent by (100) to convert the percent to a decimal. Then multiply the result by the price of the product to find the amount of money that will be given as a commission.
Applying this knowledge to the given problem, one must divide (9%) by (100) to convert to decimal form,
9% / 100 = 0.09
Now multiply the result by the price of the product (245) to find the amount given away in commission,
0.09 * 245 = 22.05

Circle the expression that has the smallest value when x = 4
5 – x 1/2 x x + 1 x - 4
9514 1404 393
Answer:
(d) x-4
Step-by-step explanation:
If we assume your answer choices are ...
(a) 5 -x = 5 -4 = 1
(b) 1/2x = 1/2(4) = 2
(c) x +1 = 4 +1 = 5
(d) x -4 = 4 -4 = 0
Then the last choice (d) x -4 has the smallest value at x=4.

The graph represents the number y of attendees to a market research conference after x years.
Write an exponential function that represents the number of attendees to the conference.
Ok, I hope im right. (Others correct me if im not. But when I worked out this problem I got y is approximatly 4,882 attendees after 6 years.
Gathering info from the graph I created a table
(0,20) , (1,30) , (2,45), ...
I found the difference between the points listed. For example, 30÷20 is 1.5. So, each point is multiplied times 1.5 to continue the sequence.
Use the equation: y=a(1+r)^t
Remember what each variable stands for. That way you can plug in the correct information
Continuing..
y=a(1+r)^t
y=20(1+1.5)^t ; combine like terms
y=20(2.5)^t
b) Plug in the # of years. 6 in our case, everywhere you see a t
y=20(2.5)^6
y is approximately equal to 4882.8125
Round because we can only have whole numbers. we're talking about people.

If r(x) = 3x - 1 and s(x) = 2x + 1, which expression is equivalent to
(6)?
)
Answer:
[tex]\dfrac{17}{13}[/tex]
Step-by-step explanation:
Given that,
r(x) = 3x - 1 and s(x) = 2x + 1
We need to find an expression equivalent to [tex]\dfrac{r}{s}(6)[/tex].
We know that,
[tex]\dfrac{r}{s}(6)=\dfrac{r(6)}{s(6)}[/tex]
Put x = 6 in the above expression
[tex]=\dfrac{3(6)-1}{2(6)+1}\\\\=\dfrac{18-1}{12+1}\\\\=\dfrac{17}{13}[/tex]
So, the equivalent expression is equal to [tex]\dfrac{17}{13}[/tex].

________name same amount
(1) Equivalent fractions (2) common denominator
Solution:
1. Equivalent fractions name the same amount.
Equivalent fractions are the same value with different numerator and denominator.
Example:
These values are same.
2. A common denominator is a common multiple of two or more denominators.
Example:
Here 6 is a common multiple of 2 and 3.
Hence the answer is (1) Equivalent fractions (2) common denominator.
