Calculate the value of x to the nearest degree
Answer:
x = 61.3°
Step-by-step explanation:
We are given the radius r = 9 cm and arc length l = 9.7 cm. We need to find the angle x in degrees.
The formula used is:
l = rФ
In our case Ф = x. So re writing the formula:
l= rx
9.7 = 9 x
=> x = 9.7 / 9
x = 1.07 radians
Converting radians into degree we need to multiply the value of x by
180/π where π = 3.14
x = 1.07 * 180/3.14
x = 61.3°

Jefferson played basketball in the park. He started playing basketball at 1:15 P.M and played for 1 hour and 25 minutes. What time did Jefferson play basketball until?
Final answer:
Jefferson played basketball until 2:57 P.M.
Explanation:
To find out what time Jefferson played basketball until, we need to add the duration of time he played to the starting time.
First, we convert the duration of time from minutes to hours. Since there are 60 minutes in an hour, 1 hour and 25 minutes is equal to 1.42 hours.
Next, we add 1.42 hours to the starting time of 1:15 P.M. This gives us the ending time of 2:57 P.M.
An animal shelter uses 41 cups of food each day to feed the dogs and cats. Each dog eats 2 cups per day. The cats eat a total of 17 cups per day. The diagram represents this situation. Which equation can be used to find d, the number of dogs at the shelter?
Answer:
The equation that can be used to find d is [tex]2d+17=41[/tex]
[tex]d=12\ dogs[/tex]
Step-by-step explanation:
Let
d -----> the number of dogs
we know that
The linear equation that represent this situation is
[tex]2d+17=41[/tex]
Solve for d
Subtract 17 both sides
[tex]2d=41-17[/tex]
[tex]2d=24[/tex]
Divide by 2 both sides
[tex]d=12\ dogs[/tex]
Final answer:
The equation to find the number of dogs at the shelter is 2d + 17 = 41, where 2d represents the total cups of food eaten by the dogs and 17 represents the cups eaten by the cats per day.
Explanation:
To find d, the number of dogs at the animal shelter, we can use the information provided to set up an equation. We know the shelter uses 41 cups of food each day in total, and that cats eat 17 cups in total per day. Since each dog eats 2 cups per day, we can represent the number of cups dogs eat as 2d, where d is the number of dogs. We can then express the total food used as the sum of the food eaten by the cats and the food eaten by the dogs, which gives us the equation:
2d + 17 = 41
This equation can be used to find the number of dogs at the shelter since solving for d would give us the total number of dogs based on their food consumption.

Step-by-step explanation:
Big Ed’s car dealership is running a special on 2008 trucks. Big Ed offers financing at a rate of 6.71% on a loan with a term of 36 months, but he requires the customer to make a down payment of 15% of the cost of the vehicle. You are interested in a Car Crusher truck that costs $25,230. Not including the down payment, how much will you pay over the lifetime of the loan? a. $27,924.84 c. $23,735.88 b. $25,789.32 d. $21,445.50 Please select the best answer from the choices provided A B C D
Answer: C
Step-by-step explanation:
25,230 x .15= 3,784.50
25,230- 3,784.50= 21,535
21,535/36= 598.20833
598.20833 x 1.0671= 638.348109
638.348109 x 36= 22,980.5319
Answer:
Letter C $23,735.84.The result varies a few dollars, because during the solution an adjustment was made to the decimals.
Step-by-step explanation:
1. Define the price of the vehicle you are going to buy with the dealer or seller
Principal: $25230
Rate= 6.71%
N= 36 months
Down payment=15% of the cost of the vehicle= (25230*0.15)=$3784.50
25230-3784.50=21445.5
2. Apply the amortization formula to determine the monthly payments. With this taxation, you will determine the payments applied to the principal and the copper of interest.
A=P*(r(1+r)^{n})/((1+r)^{n}-1).
A= amortization or monthly payments.
P=Principal
R=interest rate
N= the total number of months
a. Calculate the monthly interest rate. The annual interest rate is 6.71% percent. Divide it by 12 to get the monthly interest rate. The monthly interest rate is 0.5592 percent (6.71/12 = 0.5592)
A=21445.5*(0,005592 (1+0,005592)^{{36}})/(1+0,005592)^{{36}}-1.
A=21445.5*(0,00683/0,2223)
A=21445.5*0,03072=658.90
Total of the payment= 658.90*36=23720.40

Find the value of x for which line a is parallel to line b
Answer:
20
Step-by-step explanation:
Since we are told that line a is parallel to line b, even if it's not visible in the image, we can say that ∠5 = ∠1, since they are formed by the same line crossing parallel lines.
So, we have
∠4 = 3x
∠5 = ∠1 = 6x
Since ∠4 and ∠5 are complementary angles formed by line t, we know their sum is 180 degrees. So,
∠4 + ∠5 = 180
3x + 6x = 180
9x = 180
x = 20

The vertices of ABC are A(-2,2), B(6,2), and C(0,8). The perimeter of ABC
Answer:
The perimeter of the triangle ABC is 22.8 units
Step-by-step explanation:
* Lets study the information in the problem
- There is Δ ABC with vertices:
A (-2 , 2) , B (6 , 2) , C (0 , 8)
- The perimeter of the triangle is the sum of the length of its
three sides
* We must to find the lengths of AB , BC and CD
- The rule to find the distance between 2 points (x1 , y1) and (x2 , y2) is
√[(x2 - x1)² + (y2 - y1)²]
* Lets find the lengths of the three sides
- Length of AB
∵ A = (-2 , 2) and B = (6 , 2)
∴ AB = √[(6 - -2)² + (2 - 2)²] = √8² = 8 units
- Length of BC
∵ B = (6 , 2) and C = (0 , 8)
∴ BC = √[(0 - 6)² + (8 - 2)²] = √[6² + 6²] = √72 = 6√2 units
- Length of AC
∵ A = (-2 , 2) and C = (0 , 8)
∴ AC = √[(0 - -2)² + (8 - 2)²] = √[2² + 6²] = √40 = 2√10 units
* Now lets find the perimeter of the triangle
∵ The perimeter = AB + BD + AC
∴ The perimeter = 8 + 6√2 + 2√10 = 22.8 units
* The perimeter of the triangle ABC is 22.8 units
Answer:
The perimeter of triangle ABC = 22.78 units
Step-by-step explanation:
Formula:-
The length of line segment with end points (x₁, y₁) and (x₂, y₂) is given by,
Length = √ [(x₂ - x₁)² + (y₂ - y₁)²]
To find the each side of triangle
We have A(-2,2), B(6,2), and C(0,8).
AB = √[(6 - -2)² + (2 - 2)²] = √64 = 8
BC = √[(0 - 6)² + (8 - 2)²] = √(36 + 36) = 8.48
AC = √[(0 - -2)² + (8 - 2)²] = √(4 + 36) = 6.3
To find the perimeter of triangle ABC
Perimeter = AB + BC + AC
= 8 + 8.48 + 6.3 = 22.78 units
A certain tennis player makes a successful first serve 70% of the time. Assume that each serve is independent of the others. If she
serves 6 times, what's the probability that she gets...
All 6 serves in?
Exactly 4 serves in?
At least 4 serves in?
No more than 4 serves in?
this is a binomial problem: p = 0.7 and q = 0.3
a) (0.7)^6
b) (6C4)(0.7)^4(0.3)^2
c) Pr ( at least 4) = Pr(4) + Pr(5) + Pr(6) = (6C5)(0.7)^5(0.3) + (0.7)^6
d) Pr (no more than 4) = 1 - Pr(at least 4) = 1 - (answer from c)
The question requires understanding of binomial probability. The probability of all 6 serves, exactly 4 serves, at least 4 serves, and no more than 4 serves can be calculated using binomial distribution when each serve is an independent event.
Explanation:The subject of this question relates to probability involved in binomial distribution. Binomial distribution applies when there is a fixed number of independent trials, each with a constant probability of success. Here, a tennis player making a successful serve can be considered a success, with a probability of 0.70.
For all 6 serves in, the calculation is simply the product of the successful probability raised to the power of 6, which is (0.70)^6.For exactly 4 serves in, the calculation uses a binomial probability formula P(x=k) = C(n, k) * (p^k) * ((1-p)^(n-k)), where n is the total number of trials, k is the desired number of successes, and p is the probability of a single success. Here, C(6,4) * (0.70^4) * (0.30^2).For at least 4 serves in, it's the sum of the probabilities of getting exactly 4, 5, and 6 serves in.For no more than 4 serves in, it's the sum of the probabilities of getting exactly 0, 1, 2, 3, and 4 serves in.Learn more about Binomial Probability here:https://brainly.com/question/39666605

A rectangular swimming pool that is 10 ft wide by 16 ft long is surrounded by a cement sidewalk of uniform width. If the area of the sidewalk is 155 ft2, what is its width? A = lw 2.5 ft 5.0 ft 6.2 ft 15.5 ft
The pool has area [tex]160\,\mathrm{ft}^2[/tex].
Let [tex]x[/tex] be the width of the sidewalk. Then the combined area of the pool and sidewalk is [tex](10+x)(16+x)=160+26x+x^2[/tex], so that the area of the sidewalk alone is [tex]26x+x^2[/tex].
We're told this area is [tex]155\,\mathrm{ft}^2[/tex], so
[tex]26x+x^2=155\implies x^2+26x-155=(x-5)(x+31)=0\implies x=5[/tex]
Answer:
The width of the sidewalk is 5.0 ft.
Step-by-step explanation:
Given,
The dimension of the rectangular swimming pool is 16 ft × 10 ft,
So, the area of the pool = 16 × 10 = 160 ft²,
Let x be the uniform width of the cement sidewalk,
So, the dimension of the area covered by both swimming pool and sidewalk = (16+x) ft × (10+x) ft,
Thus, the combined area of the swimming pool and sidewalk = (16+x)(10+x) ft²
Also, the area of the sidewalk = The combined area - Area of the pool,
= (16+x)(10+x) - 160
According to the question,
[tex](16+x)(10+x)-160 = 155[/tex]
[tex](16+x)(10+x)=315[/tex]
[tex]160+16x+10x+x^2=315[/tex]
[tex]x^2+26x-155=0[/tex]
By the quadratic formula,
[tex]x=\frac{-26\pm \sqrt{676+620}}{2}[/tex]
[tex]x=\frac{-26\pm 36}{2}[/tex]
[tex]\implies x=5\text{ or } x = -31[/tex]
Side can not be negative,
Hence, the width of the sidewalk is 5.0 ft.
