You deposit $300 dollars in a savings account the account earns 10% simple interest per year whats the interest after 8 years
Answer:
$240
Step-by-step explanation:
Given data
Principal= $300
Rate= 10%
Time= 8 years
We know that the expression for the simple interest is given as
SI= PRT/100
Substitute
SI= 300*10*8/100
SI= 24000/100
SI= $240
Hence the interest is $240
?/1 A box contains 5 red marbles and 7 green marbles. Find the probability of drawing a green marble and not returning it to the box and then drawing a red marble?
Answer: 35/132
Step-by-step explanation:
probability of drawing green marble: 7/12
since the green marble drawn won't be returned to the box, the new total amount of marbles in the box is 11.
probability of red marble: 5/11
then multiply the 7/12 and 5/11 together:
35/132 which is abut 26.5%

Rhea draws rows and columns on a big piece of paper to make 16 same-sized squares. How many rows and columns does she draw? I
Answer:
4 rows and 4 columns
Step-by-step explanation:
Given
16 same sized squares
Required
Determine the number of rows and columns
Since the shape formed is a square, then the following relationships exist:
[tex]Row * Column = 16[/tex]
[tex]Row = Column[/tex]
[tex]Row * Column = 16[/tex] can then be rewritten as:
[tex]Row * Row = 16[/tex]
[tex]Row^2 = 16[/tex]
Take square roots of both sides
[tex]Row = \sqrt{16[/tex]
[tex]Row = 4[/tex]
[tex]Row = Column[/tex] implies that:
[tex]Row = Column = 4[/tex]

Which study appears to look for an association between two variables without actively manipulating either one. What are those variables ?
Solution :
The second study in the context is involved in asking for a random sample of the students at an university to provide a report the average hours of sleep that everybody get each night and also the grade point of their college appears for association between these two variables without actively changing either of one.
These variables are the grade point average of the students and the numbers of hours of sleep.

Answer:
x = 19
Step-by-step explanation:
Here, we want to find the value of x
To get this, we use one of the important circle theorems. This is the theorem of secant segments
We have this that;
8(8 + x)= 9(9 + 15)
64 + 8x = 216
8x =

The radius of Cylinder B measures ____ feet.
1.4, 2.8, 5.7
Answer:
The radius of Cylinder A measures 7 feet.
The radius of Cylinder B measures 2.8 feet.
Step-by-step explanation:
The radius of Cylinder A measures 7 feet.
because the radious is half of the diameter and 14 is the diameter
The radius of Cylinder B measures 2.8 feet.
Answer:
Cylinder A's radius is 7 because the radius is diameter divided by 2.
Cylinder B's radius is 2.8 because the height of Cylinder A is 5 times bigger than Cylinder B's height.

The cost of a holiday is £2400. Rana pays a deposit followed by monthly payments, in the ratio deposit:total of the monthly payments=3:5 she makes 6 equal monthly payments. Work out her monthly payment
Answer:
Monthly installments = £250
Step-by-step explanation:
Given
Total cost of holiday = £2400
Ratio deposit : total of the monthly payments=3:5
Total deposit made = [tex]\frac{3}{3+5} * 2400 = 900[/tex]
Total amount of the monthly payments = 2400 -900 = 1500
She pays six equal installments.
Amount of installments = 1500/6 = 250
Monthly installments = £250
Using proportions, it is found that her monthly payments are of £250.
The deposit is of x.The total of monthly payments the remainder, that is, 2400 - x.According to the ratio, we have that:
[tex]\frac{x}{2400 - x} = \frac{3}{5}[/tex]
Applying cross multiplication:
[tex]5x = 3(2400 - x)[/tex]
[tex]8x = 7200[/tex]
[tex]x = \frac{7200}{8}[/tex]
[tex]x = 900[/tex]
Hence, the monthly payments add to £1500.
She makes 6 equal monthly payments, hence:
[tex]p = \frac{1500}{6} = 250[/tex]
Her monthly payments are of £250.

Hi, can someone help with these two questions ASAP! (Ignore the multiple choice I circled, not sure if it’s correct)
Thanks!!
Answer:
1) D. [tex]y = -\frac{3}{2}\cdot x^{12} -7\cdot x^{5}+\frac{2}{3}\cdot x -10[/tex]
2) E. The coefficient of [tex]x[/tex] is -16.
Step-by-step explanation:
1) A polynomial is an algebraic expression of the form [tex]p(x) = \Sigma \limits_{i = 0}^{n} c_{i}\cdot x^{i}[/tex], where [tex]n[/tex] is the grade of the polynomial. In this case, the only equation that satisfies this definition is:
[tex]y = -\frac{3}{2}\cdot x^{12} -7\cdot x^{5}+\frac{2}{3}\cdot x -10[/tex]
Correct answer: D
2) Let [tex]p(x) = (2\cdot x + 1) \cdot (5\cdot x^{3}-8\cdot x +4)[/tex], we proceed to expand the expression by algebraic means:
[tex]p(x) = (2\cdot x + 1)\cdot (5\cdot x^{3}) -(2\cdot x +1)\cdot (8\cdot x) + 4\cdot (2\cdot x + 1)[/tex]
[tex]p(x) = 10\cdot x^{4}+5\cdot x^{3}-16\cdot x^{2}+4[/tex]
We see that coefficients for [tex]x^{2}[/tex] and [tex]x[/tex] are -16 and 0, respectively. Hence, the incorrect answer is E.

The function P(h)= 2h- 15 represents the profit a company makes selling h hot dogs. Which is the most appropriate domain of the function?
a : all positive intergers
b : all positive real numbers
c : all positive rational numbers
d : all positive irrational numbers
The requried most appropriate domain for the function P(h) would be the set of all non-negative real numbers. The domain is b, all positive real numbers.
What is a domain?The domain is defined is a set of values of the independent variable for which there is a certain value of the dependent variable exists in the range of the function.
The function P(h) = 2h - 15 represents the profit a company makes selling h hot dogs. In general, the domain of a function represents the set of all possible input values for which the function is defined.
In this case, the function can be defined for any non-negative value of h, since the company can sell any number of hot dogs, including zero. However, the function may not be defined for negative values of h, since it does not make sense to talk about selling a negative number of hot dogs.

Can someone plz help me
Answer:
41 degrees
Step-by-step explanation:
All three angles in a triangle must add up to 180 degrees. The picture already tells you that B is 63 degrees. This means A and C should both add up 117 degrees. If A is 2x+8 and B is x+7, then A+B is 3x+15. This means that 3x+15 is equal to 117 degrees.
3x + 15 = 1173x = 117 - 153x = 102x = 102/3x = 34Now that we know that x is 34, we plug it in. X + 7 becomes 34 + 7 degrees which is equal to 41 degrees.
