Answer:
68
Step-by-step explanation:
Step 1: Divide the asked hours by hours need to double
Step 2: Double the initial number of the population as per the result from step 1.
First divide 458 by 229, you will get 2
Now you double the initial population number twice
so 17 * 2 = 34 and again 34 * 2 = 68

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 .

What is another way that you could write the ratio of pennies to quarters?
Answer:
1/100 to 25/100
or
0.01 to 0.25
Step-by-step explanation:
Pennies are also known as one per cent. Cent refers to 100 and pennies are called one per cent because they value 1 out of 100. 100 pennies equal one dollar.
Similarly, one quarter is 1/4 of a dollar and 1/4 equals 25/100 when multiplying the numerator and denominator by 25.
Juanita is bringing the snacks for her daughter’s soccer team. Each girl on the team will eat 1/3 of an orange and drink one serving of juice or 1/9 of the amount in a bottle. How many oranges and how many juice bottles will she need for all 18 girls?show you work!!
Answer:
6 Oranges and 2 bottles of juice.
Step-by-step explanation:
For the amount of oranges: 18÷3=6 (take 1/3 of 18).
For the bottles of of Juice: 18÷9=2 (take 1/9 of 18).
in this question, if the numerator is 1, then just divide the number of girls by the denominator (eg. 3 and 9 in this case).
There are six oranges and two bottles of juice will she needs for all 18 girls.
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation.
For example 4/2 = 2
There are the total number of girls is 18. Each girl will eat 1/3 of an orange and one serving of juice, or 1/9 of the amount in a bottle.
To determine the number of oranges and the bottles of juice.
We have to divide the number of girls by the denominator (eg. 3 and 9 in this case).
For the number of oranges:
1/3 of 18
18 ÷ 3
18 / 3 = 6
For the bottles of Juice:
1/9 of 18
18 ÷ 9
18 / 9 = 2
Hence, there are six oranges and two bottles of juice will she needs for all 18 girls.

A quadratic function has one zero (x-intercept) at x = -5 and another zero at x = 3. What is the equation of the axis of symmetry of this function?
Answer:
x = - 1
Step-by-step explanation:
The axis of symmetry is a vertical line located at the midpoint of the zeros.
Equation is then
x = [tex]\frac{-5+3}{2}[/tex] = [tex]\frac{-2}{2}[/tex] = - 1 , that is x = - 1
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]

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.
Let me know of question or concerns about my answer.
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.

Answer:
y = x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x + 7 ← is in slope- intercept form
with slope m =
Parallel lines have equal slopes

The mean of data set A is 42. The mean of data set B is 47. The mean absolute deviation (MAD) of both data sets is 25. What is the difference of the
means as a multiple of the MAD?
The difference of the means is.......? times the MAD
HELP!
Answer:
The difference of the means is 2 times the MAD
Step-by-step explanation:
Mean of data set A = 42
Mean of data set B = 47
MAD of both data sets = 2.5
Difference of their means = 47 - 42 = 5
Thus, the difference of their means = 2 × the MAD
= 2 × 2.5 = 5
Therefore:
The difference of the means is 2 times the MAD
