In a park, a sidewalk is built around the edge of a circular garden as shown. The sidewalk is 5 feet wide, and the garden measures 10 feet across. Which measurement is closest to the circumference of the outer edge of the sidewalk?
Answer:
63 feet.
Step-by-step explanation:
The total diameter of the circular garden is given by 5ft+ 10 ft + 5 ft= 20 feet
As the circumference of the circle = 2πr where r = radius obtained by dividing the diameter by 2. Here the diameter = 20 feet and r= d/2 = 20/2 = 10 feet
Putting the values in the circumference formula
Then C= 2(22/7) (10)= 62.85 feet
Rounding gives almost 63 feet .

I also need to know what m∠cdb is
Answer:
x = 4
m<cdb = 82
Step-by-step explanation:
The exterior angle thm states that the exterior angle of a triangle is equal to the sum of the opposite interior angles:
7x + 2 + 17x = 98
24x + 2 = 98
24x = 96
x = 4
m<cdb =
y + 98 = 180
y = 180 - 98
y = 82
I'm stuck on this problem! A linear function that represents the number of video games purchased at an electronics store is compared to a different linear function that represents the amount of money the store made that day. Describe the key features of the functions that are needed to determine if these lines intersect.
Answer:
In order two straight lines in a coordinate plane intersect, they MUST have different slopes.
This condition is NECESSARY and SUFFICIENT.
Step-by-step explanation:
The key feature of the functions that are needed to determine if the lines intersect are;
The slope; rate of changeThe y-interceptSlope and y-interceptFrom straight line geometry, we can conclude that two parallel lines whose slope are equal can never intersect.
On this note, for the functions described in the question, the functions only intersect when the slopes are different.
Additionally, the functions may intersect in the event of having equal y-intercepts.

Assume that θ is an acute angle in a right triangle satisfying the given conditions. Evaluate the 5 remaining trigonometric functions. Sketch a triangle in the correct quadrant and label.
sec θ= 17/15
sin θ<0
Answer: See step by step. Replace the x with theta
Step-by-step explanation: Since sin is less than zero, and secant is positive. This means the trig values are in Quadrant 4.
We know that secФ=17/15. We need to find sin,cos,tan,csc, and cot.
We can find tangent by using the identity
[tex]tan^{2} (x)+ 1=sec^{2} (x)[/tex] where x is theta.
[tex]tan^{2} (x)+1=\frac{289}{225}[/tex]
[tex]tan^{2} (x)+\frac{225}{225} =\frac{289}{225}[/tex]
[tex]tan^{2}(x)=\frac{64}{225}[/tex]
tan x=[tex]\frac{8}{15}[/tex], Tangent in the fourth quadrant is negative so the answer is instead
[tex]tan x= -\frac{8}{15}[/tex]
We can find cotangent by taking the recipocial of tan so
[tex]cot=-\frac{15}{8}[/tex]
We can find cos by taking reciprocal of sec remeber that cosine is positive in 4th quadrant so the answer is
[tex]cos =\frac{15}{17}[/tex]
We can find sin by doing quoteint identies.
[tex]\frac{sin x}{cos x} =tan x[/tex]
[tex]\frac{ sin x}{15/17} =-\frac{8}{15}[/tex]
[tex]sin x= -\frac{8}{17}[/tex]
To find csc, take reciprocal of sine.
[tex]csc=\frac{-17}{8}[/tex]
Caleb is designing a new board game, and is trying to figure out all the possible outcomes. How many different possible outcomes are there if he flips a coin and spins a spinner with three equal-sized sections labeled Walk, Run, Stop?
Answer:
6
Step-by-step explanation:
number of ways to flip coin-2
number of ways to spin the spinner-3
2*3=6
6 different possible outcomes are there if he flips a coin and spins a spinner with three equal-sized sections.
What is Combination?A combination is a mathematical technique for determining the number of potential arrangements in a set of objects where the order of the selection is irrelevant. You can choose the components in any order in combinations. Permutations and combinations are often mistaken.
Caleb is designing a new board game, and is trying to figure out all the possible outcomes.
Outcome of Flipping a coin = 2 (Head or Tail)
and, Spinner had three equal sized section.
So, the number of possible outcomes

This line plot shows the daily rainfall amounts during the month of May.
On June 1, the rainfall amount was 1/2 of the greatest daily rainfall that fell in May.
What was the rainfall amount on June 1?
Enter your answer in the box as a fraction in simplest form.
Answer:
Rainfall amount on June 1 = ¾ inch
Step-by-step explanation:
Greatest daily rainfall in May = 1½
Rainfall amount in June 1 = ½ of 1½
Thus:
rainfall amount in June = ½ × 1½
= ½ × ³/2
= (1*3)/(2*2)
= ¾
Rainfall amount on June 1 = ¾ inch
r= 17 cm
Please help I’ll mark Brainlest
Answer:
1. r = 2.5 mm
2. r = 12ft
3. d = 34 cm
for 4-6 you use 2(pi) r
4. 25.1 ft
5. 40.8 cm
6. 22 mi
Answer is below. Look at the explanation in order to understand my answer.
To find the diameter, you'll have to get the radius in order to solve the diameter.
Since you said r = 17cm, we should be solving for diameter.
The formula is d = 2r
R will represent the radius.
You'll multiply the 2 by the radius.
Like i've said, R will represent the radius. The radius is 17.
With that being said, we can do the math.
The formula will be: d = 2r → d = 2 × 17
2 times 17 is 34.
The diameter would be 34.
