To calculate the area of Spencer's 7x7 quilt, each square patch measuring 1 3/4 inches is calculated for area (3.0625 sq. in.) and then multiplied by the total number of patches (49), resulting in a total quilt area of 150.0625 square inches.
Explanation:Spencer made a quilt for his cousin's doll with a 7x7 array of square patches. To find the area of the whole quilt, we need to calculate the area of one patch and then multiply by the total number of patches. The length of each patch is 1 3/4 inches, which can also be represented as 1.75 inches.
First, we find the area of one patch:
Area of one patch = side length × side lengthArea of one patch = 1.75 inches × 1.75 inchesArea of one patch = 3.0625 square inchesSince there are 49 patches in total (7 patches per row × 7 rows), we then find the total area:
Total area = area of one patch × total number of patchesTotal area = 3.0625 square inches × 49Total area = 150.0625 square inchesTherefore, the area of Spencer's quilt is 150.0625 square inches.
Final answer:
The area of Spencer's quilt is 150.0625 square inches.
Explanation:
Spencer made a quilt for his cousin's doll that had a 7x7 array of square patches, each measuring 1 3/4 inches in length. To find the area of the quilt, you would calculate the area of one patch and then multiply it by the total number of patches in the quilt.
First, convert the inches to a decimal to make the calculation easier:
1 3/4 inches = 1.75 inchesArea of one square patch = length × width
Since the patches are square, the length and width are the same:
Area of one patch = 1.75 inches × 1.75 inches = 3.0625 square inches
To find the total area of the quilt:
Total area of quilt = area of one patch × number of patches
There are 7 rows and 7 columns in the quilt:
Total patches = 7 × 7 = 49
Total area of quilt = 3.0625 square inches × 49 = 150.0625 square inches
Therefore, the area of the whole quilt is 150.0625 square inches.
In ΔFGH, the measure of ∠H=90°, HG = 48, FH = 55, and GF = 73. What ratio represents the tangent of ∠G?
Answer:
55/48
Step-by-step explanation:
We can find the tangent of ∠G using the trigonometrical ratios which may be expressed in the form SOA CAH TOA Where,
SOA stands for
Sin Ф = opposite side/hypotenuses side
Cosine Ф = adjacent side/hypotenuses side
Tangent Ф = opposite side/adjacent side
Considering triangle ΔFGH, where ∠H=90°
The opposite side is FH, the hypotenuse side is GF and the adjacent side is HG hence,
Tan ∠G = FH/HG
= 55/48
Answer:
55:48
Step-by-step explanation:
Given a right angles triangle ∆FGH
where ∠H=90°, HG = 48, FH = 55, and GF = 73,
Based on the diagram attached
To find the tangent of angle G, we will use the concept of SOH CAH TOA in trigonometry identity.
According to TOA:
Tan ∠G = Opposite/Adjacent
Note that the opposite side will be the side facing the angle we are considering i.e ∠G
Opposite = 55
Adjacent will be the base of the triangle = 48
Tan∠G = 55/48
The ratio that represents the tangent of ∠G is 55:48
Which sample fairly represents the population? Select two options.
measuring the height of every fiftieth person on the school roster to determine the average height of the boys in the school
A.) calling every third person on the soccer team's roster to determine how many of the team members have completed their
fundraising assignment
b.) observing every person walking down Main Street at 5 p.m. one evening to determine the percentage of people who wear
glasses
c.) sending a confidential e-mail survey to every one-hundredth parent in the school district to determine the overall satisfaction
the residents of the town
d.) taking a poll in the lunch room (where all students currently have to eat lunch) to determine the number of students who want
to be able to leave campus during lunch
Answer:
b) observing every person walking down Main Street at 5 p.m. one evening to determine the percentage of people who wear glasses.
d) taking a poll in the lunch room (where all students currently have to eat lunch) to determine the number of students who want to be able to leave campus during lunch.
Step-by-step explanation:
These are the two options that are most likely to give you a sample that fairly represents the population. In the first case, the sample that you obtain is likely to be a good representation because Main Street is a road where a great variety of people walk. Moreover, 5 pm is also a time that will allow you to see a great number of different people. The second answer will also give you a good sample, as the poll would include all students in the lunch room, which is all students in the school (the whole population).
At 11:55 p.m., Thomas ties a weight to the minute hand of a clock. The clockwise torque applied by the
weight (i.e. the force it applies on the clock's hand to move clockwise) varies in a periodic way that can be
modeled by a trigonometric function.
The torque peaks 15 minutes after each whole hour, when the minute hand is pointing directly to the right,
at 3 Nm (Newton metre, the SI unit for torque). The minimum torque of -3 Nm occurs 15 minutes
before each whole hour, when the minute hand is pointing directly to the left.
Find the formula of the trigonometric functid that models the torque applied by the weight t minutes
after Thomas attached the weight. Define the function using radians.
T(t) =(
Answer:
T(t) = 3sin((t-5)π/30)
Step-by-step explanation:
5 minutes after Thomas ties it on, the torque is zero and increasing. So, the sine function is shifted right 5 minutes. The maximum value is 3, so that is the multiplier of the sine function. The period is 60 minutes, so the coefficient of t is (2π/60) = π/30. The function you want is ...
T(t) = 3sin((t-5)π/30)
In college basketball, some teams get most of their points from just one player, and other teams are more balanced in scoring. Consider the following facts about the scoring distributions for some NCAA Division I basketball teams. Each team has 121212 players. At Baylor University, there are 666 players who each score 121212 points per game, and there are 666 players who each score 000 points per game. At the University of Maryland, 111 player scores 585858 points per game, 111 player scores 141414 points per game, and the rest of the players score 000 points per game. At Dartmouth College, 444 players score 555 points per game, 444 players score 666 points per game, and 444 players score 777 points per game.

[tex]Mean=\frac{5+5+5+5+6+6+6+6+7+7+7+7}{12} \\Mean=6\\Median=\frac{6+6}{2}=6[/tex]
The following applies:
(B) At Maryland, the mean number of points per player per game is greater than the median number of points per player per game.
(D)The mean number of points per player per game is the same at all 3 schools.
In college basketball, the mean and median number of points per player per game can be different depending on the scoring distribution of the team. At Dartmouth, the mean is greater than the median due to players scoring different points. At Maryland, the mean is also greater than the median due to a few players scoring higher points. The median and mean can vary across different schools and teams.
Explanation:Choice A: At Dartmouth, the mean number of points per player per game is greater than the median number of points per player per game. The mean is calculated by summing up all the scores and dividing by the total number of players, while the median is the middle value when the scores are arranged in increasing order. With players scoring different points per game at Dartmouth, there will be players scoring more than the mean, pulling the mean up and making it greater than the median.
Choice B: At Maryland, the mean number of points per player per game is greater than the median number of points per player per game. With only a few players scoring points other than 0, these outlier scores will cause the mean to be greater than the median.
Choice C: The median number of points per player per game can be different at different schools. In the case of Dartmouth, the median could be greater than the mean due to a large number of players scoring the same lower points per game. In the case of Maryland, with a few players scoring higher points, the median could be lower than the mean.
Choice D: The mean number of points per player per game can be different at different schools, as explained in Choices A and B.

You deposit $1500 in an account that pays 7% annual interest. Find the balance after 2 years when the interest is compounded daily.
Answer:
$1,725.39
Step-by-step explanation:
-Take 1 year =365 days.
#We calculate the effective interest rate for 7% compounded daily;
[tex]i_m=(1+i/m)^m-1\\\\=(1+0.07/365)^{365}-1\\\\=0.072501[/tex]
#We now use this rate to calculate the compounded amount after two years:
[tex]A=P(1+i_m)^n\\\\=1500(1.072501)^2\\\\=1725.39[/tex]
Hence, the balance after 2 years $1,725.39
To find the balance after 2 years with daily compounded interest, the formula [tex]A = P(1 + r/n)^(nt)[/tex] is used, with a principal of $1500, an annual rate of 7%, and n being 365. After calculations, the final balance would be approximately $1717.40.
Explanation:To calculate the balance after 2 years when the interest is compounded daily, we can use the formula for compound interest: A = P(1 + r/n)nt, where:
A is the amount of money accumulated after n years, including interest.P is the principal amount (the initial sum of money).r is the annual interest rate (in decimal form).n is the number of times that interest is compounded per unit t.t is the time the money is invested for in years.In your case, you deposit $1500 in an account that pays 7% annual interest. Since the interest is compounded daily, we will use 365 for n. Here's your calculation:
Convert the annual interest rate from a percentage to a decimal by dividing by 100: 7% / 100 = 0.07.Calculate the balance using the compound interest formula: A = 1500(1 + 0.07/365)(365)(2).Compute the value of (1 + 0.07/365) and then raise it to the power of 730 (which is 365 days times 2 years).The resulting amount is the new balance in your account after 2 years, including the interest that was compounded daily.After doing the math, your compounded balance after 2 years will be approximately:
A = 1500(1 + 0.07/365)730
A ≈ $1500 * 1.14493150684931506849
A ≈ $1717.40
This means that after 2 years, you will have approximately $1717.40.
Bus A and Bus B leave the bus depot at 7 am. Bus A takes 25 minutes to do its route and bus B takes 40 minutes to complete its route. At what time are they both back at the bus depot together?
Bus A and Bus B leave the bus depot at 7 am. At 10:20 AM are they both back at the bus depot together.
Given:
Bus A takes 25 minutes to complete its route once Bus B takes 40 minutes to complete its route To find time when they will be back at the bus depot together we need to find LCM of 25 & 40 Minutes=> 25 = 5 * 5
=> 40 = 2 * 2 * 2 * 5
LCM = 2 * 2 * 2 * 5 * 5=> = 200
Thus, After 200 minutes Buses will be back at the bus depot together
200 minutes = 3 hr 20 Minutes 7 : AM + 3 hr 20 Minutes => = 10 : 20 AMThus, At 10: 20 AM Buses would be back at the bus depot together.

Bus A and Bus B will both be back at the depot at the same time at 10:20am.
Explanation:To solve the problem, we need to determine when both Bus A and Bus B will be back at the depot at the same time. Since Bus A takes 25 minutes to complete its route and Bus B takes 40 minutes, we need to find the common multiple of these two numbers. The smallest common multiple of 25 and 40 is 200. This means that both buses will be back at the depot at the same time after 200 minutes.
Since the buses leave the depot at 7:00 am, we add 200 minutes (or 3 hours and 20 minutes) to this time. Therefore, it's at 10:20 am that both buses are back at the depot at the same time.

A truck is carrying 100 pounds of grapes, which are 99% water (and 1% skin, fiber, etc…). When the truck breaks down and the grapes sit in the back of the truck for 4 hours, they become 98% water. At that moment, how many pounds do the grapes weigh?
Answer:
The grapes have a weight of 50 pounds
Step-by-step explanation:
To calculate the weight of the grapes, we proceed as follows;
Let's categorize the skin, fiber as solids
At first, we had 1% solids and 99% water.
This means 99 pounds of water and 1 pound of solid
It must be known that the 1% solid remains the same after drying and what we have lost simply is the water,
This means that 2% of the total weight is now same 1 pound of solid after drying
Mathematically, this means
2/100 * new total weight = 1 pound
New total weight = 1 pound × 100/2 = 50 pounds

Find the missing length of the triangle.
5.6 in.
10.6 in.
Answer:
9 in
Step-by-step explanation:
The missing length of the right angle triangle is approximately 12 in.
The missing length of the right-angle triangle can be found using the Pythagorean theorem. The theorem states that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the lengths of the other two sides. In this case, the length of one side of the triangle is 5.6 in and the length of the other side is 10.6 in. Let's substitute these values into the formula:
a² + b² = c²
(5.6 in)² + (10.6 in)² = c²
31.36 in² + 112.36 in² = c²
143.72 in² = c²
Now, we can take the square root of both sides to find the length of the hypotenuse:
c = √143.72 in² ≈ 12 in
Therefore, the missing length of the right angle triangle is approximately 12 in.
