Kristina received $125 for her birthday. Her parents offered to pay her 3.5% simple interest per year if she would save it for at least one year. How much interest could Kristina earn?
Answer:
4.375 a year
Step-by-step explanation:
The formula is
Interest earned= principal ×interest rate×time
I=125×0.035×1=4.375
Kristina could earn $4.375 in simple interest.
Explanation:To calculate the interest Kristina could earn, we can use the formula:
Interest = Principal × Rate × Time
where Principal is the initial amount, Rate is the interest rate, and Time is the duration in years.
Plugging in the values, we have:
Principal = $125Rate = 3.5% = 0.035 (expressed as a decimal)Time = 1 yearUsing the formula, we can calculate the interest:

Marjorie has 36 boxes of video games to unpack and put on shelves.Each box contains 28 video games.How many video games in all need to be unpacked.
36 boxes
28 video games per box
That means, we have to multiply 36 by 28 to get the total number of video games.
36 x 28 = 1008
Therefore, 1,008 video games need to be unpacked.
Marjorie must unpack a total of 1008 video games, calculated by multiplying 36 boxes by 28 video games per box.
Marjorie has 36 boxes of video games to unpack, with each box containing 28 video games.
To find out the total number of video games that need to be unpacked, we simply multiply the number of boxes by the number of video games in each box.
The calculation is as follows:
36 boxes × 28 video games per box = 1008 video games
Therefore, Marjorie needs to unpack a total of 1008 video games.
Mr. Hayes has Ill straw bundles to use for bedding in his horse stalls. What is the
greatest number of stalls he can fill if each stall holds exactly 4 bundles of
straw?
We have been given that Mr. Hayes has 111 straw bundles to use for bedding in his horse stalls. We are asked to find the greatest number of bundles that he can fill if each stall holds exactly 4 bundles of straw.
To solve our given problem, we will divide 111 by 4.
[tex]\text{Greatest number of stalls that can be filled}=\frac{111}{4}[/tex]
[tex]\text{Greatest number of stalls that can be filled}=27.75[/tex]
Since 0.75 is not an integer, so Mr. Hayes cannot fill 0.75 of a stall. Therefore, the greatest possible number of stalls will be 27.
A sector with an area of 48\pi cm^(2) has a radius of 16 cm. what is the central angle measure of the sector in radians
Answer:
The central angle is = 3/8 π
Step-by-step explanation:
To calculate the area of the sector, we will follow the steps below;
First write down the formula for calculating the area of a sector.
If angle Ф is measured in degree, then
area of sector = Ф/360 × πr²
but if angle Ф is measured in radians, then
area of sector = 1/2 × r² × Ф
In this case, since we are asked to find the central angle measure of the sector in radians, then we will use the second formula
area = 48π cm² and radius = 16 cm
area of sector = 1/2 × r² × Ф
48π = 1/2 × 16² × Ф
48π = 1/2 ×256 × Ф
48π = 128×Ф
Divide both-side of the equation by 128
[tex]\frac{48}{128}[/tex] π = Ф
Ф = [tex]\frac{48}{128}[/tex] π
The right-hand side can be reduced to its lowest term
Ф = 48 ÷ 16 / 128 ÷16 π
Ф = 3/8 π
145 = 3500(0.06)(t)
Answer:
t = 29/42
Step-by-step explanation:
in this equation you have to first multiply everything out on the right side. 3500 * 0.06 = 210.
Now you have 145 = 210t
divide by 210 on both sides
145/210 can be simplified to 29/42
so t = 29/42

Riley and Jace work at a dry cleaners ironing shirts. Riley can iron 25 shirts per hour, and Jace can iron 30 shirts per hour. Riley worked 3 more hours than Jace and they ironed 460 shirts between them. Write a system of equations that could be used to determine the number of hours Riley worked and the number of hours Jace worked. Define the variables that you use to write the system.
Answer:
25r +30j = 460r - j = 3Step-by-step explanation:
Let r and j represent Riley's hours and Jace's hours, respectively. The equations could be ...
25r +30j = 460
r - j = 3
__
The solution is (r, j) = (10, 7).
The system of equations that could be used to determine the number of hours Riley and Jace worked is: R = J + 3 and 25R + 30J = 460, where R represents the number of hours Riley worked, and J is the number of hours Jace worked.
Explanation:Let's define our variables first. Let's let J represent the number of hours Jace worked and R represent the number of hours Riley worked.
From the information given, we know that Riley worked 3 more hours than Jace. So we can write this as an equation: R = J + 3.
We also know that between them, they ironed 460 shirts. We can express this as another equation by multiplying their per-hour output by the number of hours they worked, then adding the two together: 25R + 30J = 460.
So our system of equations is: R = J + 3 and 25R + 30J = 460.

In Prodigy, Luigi's inventory weighs 3 grams. He is collecting old socks,
each sock weighs grams.
Let the total weight of his inventory be represented by i.
Let the number of old socks collected be represented by s.
An equation that represents this scenario is:
i = s +3
What is the total weight of his inventory if he collects 27 socks?
Answer as a decimal.
Final answer:
The total weight of Luigi's inventory if he collects 27 socks is 30 grams.
Explanation:
The equation i = s + 3 represents the scenario where Luigi's inventory weight is represented by i and the number of old socks collected is represented by s. According to the equation, the total weight of Luigi's inventory is equal to the number of socks collected plus 3 grams.
If Luigi collects 27 socks, we can substitute s with 27 in the equation to find the total weight of his inventory.
i = 27 + 3 = 30 grams.

The distance around a circular dance hall room is 135 feet. What is the longest distance around the dance hall?
Answer: 43feet
Step-by-step explanation:
Perimeter= 135 feet
Since perimeter= 2πr
135 = 2πr
Recall that π = 3.14
135 = 2 × 3.14 × r
135 = 6.28 × r
135 = 6.28r
r = 135/6.28
r = 21.5
d = 2r
d = 2 × 21.5
d = 43 feet
Answer:
42.95 feet
Step-by-step explanation:
In this question, we are tasked with calculating the distance around the dance hall that is the greatest.
Now, to answer this, we must have at the back of our mind that the dance hall is circular in shape. Thus, the greatest distance that could arise is the distance from one edge of the dance hall to the other end of the dance passing exactly through the center of the dance hall.
This distance described above is the diameter of the dance hall.
Notice we were given a length in the question? This length refers to the circumference around the circular dance hall.
Reframing then question, we were just told to calculate the diameter of a circle given the circumference of the circle.
Mathematically, circumference C of a circle = 2 * pi * r
Recall, mathematically also 2r = D
so we can say C = pi * D
Using the value of 22/7 for pi and the value of the circumference in the question, we have;
135 = 22/7 * D
D = (7 * 135)/22
D = 42.95 feet
Here is the equation of a circle in standard form.
(x + 10)2 + (y + 9)2 = 100
What are the coordinates of the center?
A. (-10, -9)
B. (9, 10)
C. (-9, -10)
Answer:
A
Step-by-step explanation:
The equation is in the standard form of a circle:
(x – h)^2 + (y – k)^2 = r^2
where (h,k) is the center, and r is the radius.
If we compare the 2 equations:
(x – h)^2 + (y – k)^2 = r^2
(x + 10)^2 + (y + 9)^2 = 100
We can see that the center is (-10, -9).
This is because (x- -10) will become (x+10), and (y- -9) will become (x+9).
So, choice A is correct
Answer:
A
Step-by-step explanation:
The equation of a circle in standard form is: [tex](x-h)^2+(y-k)^2=r^2[/tex], where (h, k) is the center and r is the radius.
Here, our equation is: [tex](x+10)^2+(y+9)^2=100[/tex] , which means that h = -10 and k = -9. Then, the center is (-10, -9).
The answer is A.

AOC and BOD are diameters of a circle, centre O. prove that triangle ABD and triangle DCA are congruent by RHS.
Triangle ABD and triangle DCA can be proven congruent using the RHS congruence criterion.
Explanation:To prove that triangle ABD and triangle DCA are congruent using the RHS (Right Angle, Hypotenuse, Side) congruence criterion, we need to show that they have a right angle, an equal hypotenuse, and an equal side adjacent to the right angle.
Since AOC and BOD are diameters of the circle, we know that they are perpendicular to their respective radii.Therefore, angle AOB is a right angle, and triangle AOB is a right triangle.Since AO and BO are radii of the same circle, they have the same length, making the hypotenuse AB of triangle ABD equal to the hypotenuse BD of triangle DCA.Furthermore, angle ABD and angle CDA are both subtended by the same arc AD, so they are equal in measure.Finally, the adjacent sides to the right angles, AB and DC, are also equal as they are radii of the circle.Therefore, by the RHS criterion, triangle ABD and triangle DCA are congruent.
