Find the perimeter and area of a rectangle with a width of 3 1/2 cm and length of 7 1/2 cm.
Answers
Answer:
perimeter = 22 cm
area = 105/4
Step-by-step explanation:
to find perimeter, you add the width and the length togther and multiply by 2. so 2(3 1/2 + 7 1/2) = 22, which is the perimeter. to find are you multiply width and length, which is 3 1/2 x 7 1/2. first change both into improper fractions, and multiply. the area is 105/4, which can't be simplified anymore. hope this helped a bit, have a great day
I am currently 13 times as old as my granddaughter. Next year, I will be 11 times as old as my granddaughter. How old am I now?
Answers
Answer:
65 years old.
Step-by-step explanation:
Define the variables:
Let x be the age of the granddaughter.Let y be the age of the grandparent.Given:
I am currently 13 times as old as my granddaughter. Next year, I will be 11 times as old as my granddaughter.Create two equations with the given information and defined variables:
\(\begin{cases}y = 13x\\y + 1 = 11(x + 1)\end{cases}\)
Substitute the first equation into the second equation and solve for x:
\(\implies 13x+1=11(x+1)\)
\(\implies 13x+1=11x+11\)
\(\implies 2x=10\)
\(\implies x=5\)
Substitute the found value of x into the first equation and solve for y:
\(\implies y=13(5)\)
\(\implies y=65\)
Therefore, the age of the grandparent now is 65 years.
Given statements:
I am currently 13 times as old as my granddaughter. Next year, I will be 11 times as old as my granddaughter.Let us represent the character's age by variables. Assuming that the grandparent's age is G and the granddaughter's age is D. Now, using the obtained variables and the statements, create two equations that represents the provided statements. Then, we can compare the equations and simplify if needed to determine the value of the variables.
\(\implies \left[\begin{array}{ccc} \text{G = 13D} \\ \text{G + 1 = 11(D + 1)}\\\end{array}\right]\)
Since G = 13D is in the form of direct variation, we can substitute the value of G into the second equation to determine the value of D (the age of the granddaughter). Then, we can substitute the value of D into any of the two equations to determine the age of the grandparent.
⇒ G + 1 = 11(D + 1)⇒ G + 1 = 11(D + 1) [G = 13D]⇒ 13D + 1 = 11(D + 1)To solve for D, simplify both sides of the equation by using the distributive property. We need to simplify both sides of the equation so that we can isolate the variables on the other side of the equation.
⇒ 13D + 1 = 11(D + 1)⇒ 13D + 1 = 11D + 11Isolate the variables on one side. This step is necessary because it can cancel out the extra variable and simplify the other variable. To do this, you can either add or subtract on both sides of the equation.
Note: I am subtracting 11D on both sides of the equation since it is my preference. But you can also subtract 13D on both sides of the equation.
⇒ 13D + 1 - 11D = 11D + 11 - 11D⇒ 1 + 2D = 11To further isolate 2D, we need to subtract 1 on both sides of the equation to cancel out the 1 on the left-hand side of the equation. Then, we have:
⇒ 1 + 2D - 1 = 11 - 1⇒ 2D = 10But the variable is still not completely isolated since there is a coefficient being multiplied to D. To isolate the coefficient from the variable, we will need to divide the coefficient (2) on both sides of the equation.
⇒ 2D = 10⇒ 2D/2 = 10/2Then, simplify both sides of the equation. Eventually, we will have a variable on one side and a numerical value on the other side.
⇒ 2D/2 = 10/2⇒ D = 5Now we know the age of the granddaughter, we can substitute the age of the granddaughter into one of the equations and simplify it to determine the age of the grandparent. I am going to choose G = 13D since it is easier to simplify. Then, we will substitute the value of D into the equation.
⇒ G = 13D ⇒ G = 13(5)⇒ G = 65 yearsTherefore, the age of the grandparent is 65 years.
A spinner is divided into five sections, labeled A, B, C, D, and E. Devon spins the spinner 50 times and records the results in the table.
Based on the table above, make a prediction for 200 trials.
Answers
Answer:
Prediction for 200 trials: A- 40 times, B- 56 times, C- 48 times, D- 32 times, E- 24 times
Step-by-step explanation:
A=10/50=1/5 (then multiply by 200)
B=14/50=7/25 (then multiply by 200)
C=12/50=6/25 (then multiply by 200)
D=8/50=4/25 (then multiply by 200)
E=6/50=3/25 (then multiply by 200)
In the 50 trials, we see that section A occurred 9 times out of 50, or 18% of the time. Similarly, section B occurred 10 times out of 50, or 20% of the time. Section C occurred 15 times out of 50, or 30% of the time. Section D occurred 8 times out of 50, or 16% of the time. Finally, section E occurred 8 times out of 50, or 16% of the time.
Assuming that the same proportion holds for 200 trials, we can predict the number of occurrences for each section as follows:
- A: 0.18 x 200 = 36 occurrences
- B: 0.20 x 200 = 40 occurrences
- C: 0.30 x 200 = 60 occurrences
- D: 0.16 x 200 = 32 occurrences
- E: 0.16 x 200 = 32 occurrences
Therefore, based on the table above, we can predict that in 200 trials, section C will occur the most frequently (60 times), followed by section B (40 times), section A (36 times), and sections D and E equally (32 times each). It's important to note that this is just a prediction based on the observed data, and the actual results may vary due to chance.

For case A:

For case B:

27.5+220 false
For case D:

55+110
165 false
Hope it helped!
Answer: C
Step-by-step explanation:
Well Well, so from Lesson 4 to 6 The $ added is 55 then from lesson 6 to 9 the $ added is 82.50. So you subtract 82.50-55=$27.50 which is the cost per lesson. Then to find out the initial fee you do 4*27.50=110 which means that you subtract 145-110=$35 and you get the initial fee. What you do to get the the initial fee is you go back to 0 lessons that's why I multiplied 4*27.50 and subtract that from the cost 145 and u get the initial fee! Hope this helped you comprehend what they're asking you!

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answers
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:
18 = 2πr
Solving for r, we get:
r = 9/π ≈ 2.864 feet
Now we can use the formula for the area of a circle:
A = πr^2
Substituting the value we found for r, we get:
A = π(2.864 ft)^2 ≈ 25.85 ft^2
Therefore, the approximate area inside the circular park is approximately 25.85 square feet.

Matea recorded that water levels in one part of the river fell 1.05 millimeters per year for 2.48 years. Describe how you could estimate the total variation in water level
Answers
Answer:
The decrease of the decimal rate -1.05 mm/year can be rounded to -1. You don’t need to round 2.48 because you’re multiplying by -1. Since -1.05 is negative and rounded to a greater value, the estimate could be adjusted to a slightly lesser value, maybe -2.5 or -2.6.
Step-by-step explanation:
Answer:
The decrease of the decimal rate -1.05 mm/year can be rounded to -1. You don’t need to round 2.48 because you’re multiplying by -1. Since -1.05 is negative and rounded to a greater value, the estimate could be adjusted to a slightly lesser value, maybe -2.5 or -2.6.
Step-by-step explanation:
If you don't want to use that answer this is what they are looking for
Round -1.05 mm/year to –1.
Estimate the total variation as (-1)(2.48) = -2.48 mm.
Because -1.05 is negative and rounded to a greater value, adjust the estimate to -2.5 or -2.6 millimeters

Step-by-step explanation:
Distance is the difference between two positions. That is x1- x2 Since both numbers were negative, you would want the absolute value of one plus the other, because subtracting negative results in a positive. For this example the distance would look more like this:
