In circle R with m angle QRS= 90 and QR= 3 units find the length of arc QS round to the nearest hundredth
Answer:
4.71 units
Step-by-step explanation:
The formula for arc length =
2πr × θ/360
From the above question,
r = QR = 3 units
θ = angle QRS= 90 = 90°
The length of the arc is calculated as:
2 × π × 3 × 90/360
= 4.7123889804 units
Approximately to the nearest hundredth = 4.71 units
A researcher is 95% confident that the interval from 3.6 hours to 8.1 hours captures μ = the true mean amount of daily screen time for US adults.
Is there evidence that the true mean number of hours of screen time for US adults is greater than 3.5?
No. There is not evidence that the population mean is greater than 3.5, because 3.5 is not within the 95% confidence interval.
No. There is not evidence that the population mean is greater than 3.5, because there are values within the 95% confidence interval other than 3.5.
Yes, there is evidence that the population mean is greater than 3.5, because 3.5 is not within the 95% confidence interval.
Yes, there is evidence that the population mean is greater than 3.5, because the entire 95% confidence interval is greater than 3.5.
Answer:
d) Yes, there is evidence that the population mean is greater than 3.5, because the entire 95% confidence interval is greater than 3.5.
Step-by-step explanation:

The evidence that the true mean number of hours of screen time for US adults is greater than 3.5 is there is evidence that the population mean is greater than 3.5, because 3.5 is not within the 95% confidence interval.
What is the confidence interval?It is an estimate of an interval used in statistics, which contains a population parameter. This unknown population parameter is found through a sample model calculated from the collected data.
The confidence level index is directly linked to the margin of error. In that case, there is evidence that the population mean is greater than 3.5, because 3.5 is not within the 95% confidence interval.

Which value of x makes the equation 0.75(x + 20) = 2 + 0.5(x - 2) true?
Answer:
x = -56
Step-by-step explanation:
0.75(x + 20) = 2 + 0.5(x - 2)
0.75x + 15 = 2 + 0.5x - 1
0.25x = -14
x = -14/0.25
x = -56

Dylan and his friend Lamar volunteered to bring sandwiches for lunch at a homeless shelter. They bought 8 loaves of bread. Each loaf had 16 slices of bread. The boys used up all the bread to make the sandwiches. They used 2 slices to make each sandwich. How many sandwiches did they make for the shelter?
Thanks For answering!
Answer:
64 slices
Step-by-step explanation:
The first step to solving this is to find out how many slices of bread there were in total. We know that each loaf of bread had 16 slices, and we know that there were 8 loaves. To get the amount of slices, we multiply the amount of slices in each loaf by the number of loaves there are.
16⋅8=128 slices of bread in total
Now that we know the total number of slices, we need to find how many sandwiches they made. If they used two slices per sandwich, we would divided the total number of bread slices by two.
128÷2=64.

Sammie is buying an airline ticket. The ticket costs $125. She earns $12 an hour and has already saved $40. Write an inequality to find out how many hours (h) Sammie needs to work in order to buy her ticket. Do not solve.
Answer:
125=12x+40
Step-by-step explanation:
Let the number of hours be x
And the total amount be =$125
We already have $40
Hence the expression is
125=12x+40
If we solve for x, the answer gotten is the number of hours
Find the value of x.

Answer:
x=8
Step-by-step explanation:
13=x+5
8=x
Answer:
x = 8
Step-by-step explanation:
Okay, so the top and bottom of a parallelogram are equal (or else it would be a trapezoid), so we just have to construct our cute lil algebraic expression:
x + 5 = 13
So now we have to do the inverse operations thingy:
13 - 5 = 8
So x = 8

4,12,20 find the 41st term
Answer:
The 41st term of the given series is 324
Step-by-step explanation:
a= 4
a2= 12
d= a2-a
d= 12-4 = 8
now, we have to find 41 term that is a41
a41 = a+ 40d
a41= 4+ 40× 8
a41= 4+ 320
= 324
therefore the 41st term is 324
Answer:
324
Step-by-step explanation:
The sequence observed appears to be an arithmetic sequence. The formula for an arithmetic sequence is an = a1 + (n - 1)d, where an is the nth term, a1 is the first term, n is the term position, and d is the common difference. Let's write down what we know.
n = 41
a1 = 4
d = 8
So, let's plug our values into the equation and solve.
an = 4 + (41 - 1)8
an = 4 + (40)8
an = 4 + 320
an = 324

1. 12m + 24m
2. 90a - 30a
3. 14b + 15b + 8
4. 58d + 25 - 22d
5. 3(14 + 15f) + 79
6. 20(18 + 5t) - 47 + 28t
Step-by-step explanation:
These problems are about like terms. Those are terms that are alike (same variables) but the coefficients (numbers in front) can be different.
1. 12m + 24m = 36m
2. 90a - 30a = 60a
Example: 6k + 8k + 10 = 14k + 10 (the part of the expression that's just a number does not combine with the parts that have variables).
3. 29b + 8
4. 36d + 25 (the terms with d in them combine--they don't have to be back-to-back)
5. This is about the Distributive Property; first multiply 14 + 15f both by 3, then look for opportunities to combine like terms.
3(14 + 15f) + 79 = 42 + 45f + 79 = 121 + 45f
6. 20(18 + 5t) - 47 + 28t = 360 + 100t - 47 + 28t
= 313 + 128t
How do I solve this arithmetic sequence?
Answer:
7 times 50=350
Step-by-step explanation:
Answer:
a₅₀ = 252
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 7 and d = 5 , then
a₅₀ = 7 + (49 × 5) = 7 + 245 = 252
Mike is reading a map with a scale of 1 in. = 35 mi. On the map, the
distance Mike must drive is 5.5 in. What is the actual distance he has to
travel?
Answer:
Actual distance represented by 5.5 inch of map distance is
[tex]192.5[/tex] miles
Step-by-step explanation:
Given,
The scale of map -
1 inch on map is equal to 35 miles.
Distance measured by mike on map is equal to 5.5 inch
Actual distance represented by 5.5 inch of map distance is

Identify the coordinates of triangle ABC when it is dilated by a scale factor of 2 from the origin (0,0).
Answer:
[tex]A' = (-4,4)[/tex]
[tex]B' = (2,6)[/tex]
[tex]C' = (2,0)[/tex]
Step-by-step explanation:
Given [Missing from the question]
[tex]A = (-2,2)[/tex]
[tex]B= (1,3)[/tex]
[tex]C= (1,0)[/tex]
[tex]k = 2[/tex] --- scale factor
Required
The new coordinates
The new coordinate is calculated by:
[tex]New = Old * k[/tex]
So, we have:
[tex]A' = A * 2[/tex]
[tex]A' = (-2,2) * 2[/tex]
[tex]A' = (-4,4)[/tex]
[tex]B' = B * 2[/tex]
[tex]B' = (1,3) * 2[/tex]
[tex]B' = (2,6)[/tex]
[tex]C' = C * 2[/tex]
[tex]C' = (1,0) * 2[/tex]
[tex]C' = (2,0)[/tex]
Bubble algae cells can grow up to 5 cm in diameter. Calculate the surface area : volume ratio of this cell.
Answer:
6:5
Step-by-step explanation:
Bubble algae cells can grow up to 5 cm in diameter. Calculate the surface area : volume ratio of this cell.
The algae is spherical in nature
Volume of the algae =4/3 pi r³
Volume of the algae = 4/3×pi×2.5³
Volume of the algae = 62.5/3 pi
Surface area = 4pi r²
Surface area = 4pi ×2.5²
Surface area = 25pi
Taking their ratio
surface area : volume ratio
= 25pi:62.5/3 pi
= 25 × 3/62.5
= 1.2
Hence the required ratio is 12/10 which is 6:5
