Answer: 37 pieces of candy
Step-by-step explanation:
24-8.50 is 15.50 she wants to save 6.25, so, 15.50-6.25 is 9.25. 9.25 divided by the cost of each candy (0.25) is 37
You deposit $2000 in an account that pays 7% interest compounded semiannually. After 5 years, the interest rate is increased to 7.28% compounded quarterly. What will be the value of the account after a total of 10 years?
The value of the account will be $_____. (Round to the nearest dollar as needed.)
9514 1404 393
Answer:
$4047
Step-by-step explanation:
For an interest rate r compounded n times per year for t years, the effective multiplier is ...
(1 +r/n)^(nt)
The multiplier for the first 5 years is ...
(1 +0.07/2)^(2·5) = 1.41059876
The multiplier for the last 5 years is ...
(1 +0.0728/4)^(4·5) = 1.43437218
Then the account value at the end of 10 years is ...
$2000(1.41059876)(1.43437218) ≈ $4047 . . . . balance after 10 years
Please help me with this question!! I also need the steps
Hi there!
[tex]\large\boxed{x = \frac{\pi}{3} \text{ and } \pi}[/tex]
We are given:
cos(7x)cos(4x) = -1 - sin(7x)sin(4x)
Begin by moving all terms with variables to one side:
cos(7x)cos(4x) + sin(7x)sin(4x) = -1
The corresponding trig identity is cos(A - B). Thus:
cos(7x - 4x) = cos(7x)cos(4x) + sin(7x)sin(4x) = -1
cos(3x) = -1
cos = -1 at π, so:
3x = π
x = π/3
We can also find another solution. Let 3π = -1:
3x = 3π
x = π
Thus, solutions on [0, 2π) are π/3 and π.

What is the equation of the line that has a slope of -3 and goes through the point (3, -1)?
Answer:
y = -3x + 8
Step-by-step explanation:
plug in the slope of -3 and the point (3, -1) into the equation: y = ax + b to find b. (the slope of -3 = a)
=> -1 = 3(-3) + b
=> b = 8
plug in b= 8 & the slope of -3 into the equation: y = ax + b
=> y = -3x + 8

Which of the following could be a function with zeros of —3 and 2? А f(x) = (x - 3)(x + 2) B f(x) = (x = 3)(x - 2) © f(x) = (x+3)(x - 2) D f(x) = (x+3)(x + 2)
Answer:
C
Step-by-step explanation:
to find the zeros you look at what value you would fill in for x to make zero, so (x+3) would have a zero of -3 and (x-2) would have a zero of 2

Answer:
(-1,-2)
Step-by-step explanation:
For a point (a,b) rotated 90° counterclockwise about the origin, it's new coordinates are (-b,a).
So since C is originally (-2,1), it's new coordinates are (-1,-2)

N is to the left of the zero which means it is a negative number.
P is the the right of zero which means it is a positive number.
A negative number is less than a positive number, so the answer would be:
The number with the least value is N
The number with the greatest value is P

. Duke's photography pays $9 for a 5x7 photograph.
If the photograph is sold for $15, what is the
percent of markup based on cost?
Answer:
the markup percentage is 66.67%
Step-by-step explanation:
The computation of the percent of markup based on cost is shown below:
= (Selling price - paid price) ÷ (paid price)
= ($15 - $9) ÷ ($9)
= 66.67%
By taking the difference of the selling price & paid price and then divided it by paid price we can get the percentage of markup
Hence, the markup percentage is 66.67%
Somone PLEASE answer this thanks!
A movie complex is showing the same movie in three theaters. In theater A, 44 of the 80 seats are taken. In theater B, 42 seats are taken and 28 seats are empty. In theater C, 27 of the 90 seats are empty. Which theater has the greatest percent of its seats taken? Which theater has the greatest of its seats taken ?
Answer:
Theater C
Step-by-step explanation:
Theater A has 80 seats, 44 of which are taken. 44/80 can be simplified to 11/20, which is 0.55 in decimal form, and 55% in percent form.
Theater B has 70 seats, because 42+28 = 70. 42 of those 70 seats are taken. 42/70 is 60%
Theater C has 90 seats, and because 27 are empty, we can subtract 27 from 90, which leaves us at 63 seats are taken. 63/70 is 70%
70% is the biggest percentage, so Theater C has the greatest seats taken.
I hope this helps! :))

Answer:
6 and 8 cm
Step-by-step explanation:
As both are similar, ratio of correspondening sides must be constant.
10/5 = x/3 = y/4
2 = x/3 = y/4
Thus,
x = 2*3 = 6 cm
y = 2*4 = 8 cm

The amount of a radioactive isotope decays in half every year. The amount of the isotope can be modeled by f(x) = 346(one half)x and f(1) = 173. What does the 173 represent?
9514 1404 393
Answer:
f(1) = 173 = the amount remaining after 1 year
Step-by-step explanation:
The function definition tells you f(x) is the amount of the isotope remaining after x years. Then ...
f(1) = 173 = the amount remaining after 1 year

Find the area of the shaded region
Answer:
Step-by-step explanation:
Area of the Shaded region = area of the Trapezoid - Area of the triangle
Area of the Trapezoid
b1 = 14
b2 = 26
h = 15
Area = (b1 + b2 ) * h / 2
Area = (14 + 26) * 15/2
Area = 40 * 15/2
Area = 300 in^2
Area of the triangle
Area = 1/2 b * h
b = 26
h = 15 - 6
h = 9
Area = 1/2 * 26 * 9
Area = 117 in^2
Area of the shaded region
Area of the shaded region = 300 - 117
Area of shaded region = 183

round 36 to the nearest hundredth. for the brainiest
36 to the nearest hundredth is just 36
To round 36 to the nearest hundredth consider the thousandths' value of 36, which is 0 and less than 5. Therefore, the hundredths' value of 36 remains 36
Answer:
Round 36 to the nearest tenth, Leaving only one number after the decimal point, Then you have come to the right post.
Step-by-step explanation:
Round off to nearest 10. Rounding every place-value of number. Round off a number to the nearest tens round off to the nearest multiple of ten.
A large number may be rounded off to the nearest 10.

A car travels 30 1/5 miles in 2/3 of an hour what is the average speed in miles per hour of the ca A car travels 30 1/5 miles in 2/3 of an hour what is the average speed in miles per hour of the car
Answer:
45.3 miles/h
Step-by-step explanation:
let 'x' be the speed of the car.
60 × 2/3 = 120/3 = 40
30 × 1/5 = 151/5
151/5 /40 = x / 60
151 / 200 = x / 60
=> x = (151×60) / 200
=> x = 45.3
