In December, Gyu Ha could type 35 words per minute. In March, he could type 42 words per minute. What is his percent of change in the number of words per minute he could type from December to March?
Answer:
what 35 minus 42
Step-by-step explanation:
Answer:
20%
Step-by-step explanation: you just multiply 35 bye different percent and obviously more than 50 is too much in less than 10 is too little so just multiply from numbers that you know are close and from 35 to 42 is seven so once you multiply those percent by 35 you have to get seven as your answer

The range is touchdowns. The interquartile range is touchdowns.
Using the statistical formula, the median of the given data-set is 20.5.
It is given that
Number of touchdowns in 10 sessions are:
29, 5, 26, 20, 23, 18, 17, 21, 28, 20
What is a median?The median is the middle number in a sorted, ascending, or descending, list of numbers and can be more descriptive of that data set than the average.
For the median, let us arrange the given data in ascending order.
5, 17, 18, 20, 20, 21, 23, 26, 28, 29
Number of terms = 10
Median of n terms when n is even is given by:
(n/2^th term+ (n/2 +1)^th term)/2
n/2 th term = 5th term = 20
(n/2+1)th term = 6th term = 21
So median= (20+21)/2 = 20.5

What is the area of a circular sector?The area of a circular sector is the total space occupied by it. The sector area is half of the product of the square of radius of the circle and the central angle.
It can be calculated as,
[tex]A_{sector}=\dfrac{d^2\theta}{8}[/tex]
Here, (d) is the diameter of the circle and (θ) is the central angle.
The central angle of the sector is 5π/7 radians and the diameter of the sector is 5.6 in.
Put the values in the above formula as,

А
B
On each trial of the experiment, the number cube is tossed once and the arrow is spun once.
What is the sample space for the experiment?
Answer:
We have two independent events.
A number cube, with 6 possible outcomes.
A spinner, with 3 possible outcomes.
Each element in the combined sample space will be something like:
(outcome of the number cube, outcome of the spinner).
Then the number of possible outcomes in the sample size is equal to the product between the number of outcomes in each event.
Sample space size = 6*3 = 18.

Help me on calculating the area of the shaded part
Answer:
[tex]1051 .55 {mm}^{2} [/tex]
Step-by-step explanation:
Find the area of the square - area of 4 sectors
We'll use the formula to find one sector area
[tex]a = \frac{1}{2} \times {r}^{2} \times x[/tex]
where r is the radius of one sector and x is the angle in radians
Since each angle is in a square, the angle of the sectors is 90 degrees.
Convert degrees to radians
[tex]90 = \frac{1}{2} \pi \: rad[/tex]
The radius of one sector is given by 70mm/2=35mm
One sector area:
[tex] \frac{1}{2} \times {35}^{2} \times \frac{1}{2} \pi = 306.25\pi[/tex]
Area of all 4 sectors:
[tex]4 \times 306.25\pi = 1225\pi[/tex]
Area of the square:
[tex]70 \times 70 = 4900[/tex]
Hence, Area of square - 4 Sectors:
[tex]4900 - 1225\pi = 1051.55 {mm}^{2} (2dp)[/tex]
Answer:
1053.50 mm^2
Explanation:
first calculate the area of square ABCD
area of ABCD = AB × AB
= 70 × 70 = 4900 mm^2
if you look closely, there are 4 quater-circles with radius (AB/2 = 35 mm) and their center A,B,C and D.
now
area of any one quater circle =( pi × r^2 )/4
area of 4 quater circle =(pi × r^2)
where, pi = 3.14 and r = radius of quater circle
area of 4 quater-circle = (3.14 × 35^2)= 3846.50 mm^2
hence area of shaded region = area of square - area of 4 quater circles
= 4900 - 3846.50
=1053.50 mm^2
(a) If NC. 200 = 2.45 Australian dollar and 8816 Australian dollar 8152 Canadian dollar. how much Canadian dollar can be exchanged with NC, 45000 ?
The amount of Canadian dollar that can be exchanged with NC. 45000 is; 533.69 canadian dollar
What is the currency equivalent?
We are told that;
NC. 200 = 2.45 Australian dollar
8116 Australian dollar = 8152 canadian dollar
Thus;
NC per Australian dollar = 200/2.45 NC/AUS Dollar
Thus;
200/2.45 NC = 1 Australian dollar
8116/8152 Australian dollar = 1 canadian dollar
Since 1 Australian dollar = 200/2.45 NC , then
8116/8152 Australian dollar = 8116/8152 * 200/2.45
⇒ 81.272 NC
Thus;
81.272 NC = 1 canadian dollar
Then; NC.45000 = 45000/81.272 = 533.69 Canadian dollar

Find the value of x in the parallelogram.
xº
63º
Answer:114Step-
Step-by-step explanation:
Answer: x = 114Step-by-step explanation:Angle A is equivalent to angle D because of the properties of parallelograms. So we know angle A is 66 degrees. Angles C and B also have the same measure because they are opposite angles. The sum of all four angle measures is 360 degrees. Therefore, you can write this equation:m<A + m<B + m<C + m<D = 360 Step 1) plug in the degree measure of each angle that you know. (I will represent angle C with “x”)66 + m<B + x + 66 = 360(We know that the m<B is the same as m<C, so we can plug in “x” for m<B)66 + x + x + 66 = 360(x + x is the same as 2x)66 + 2x + 66 = 360(66 + 66 = 132)132 + 2x = 360Step 2) solve for x by continuing with this equation: 132 + 2x = 360(Subtract 132 from both sides)2x = 228(Divide by 2 on both sides)x = 228/2(228/2 equals 114)x = 114Check:Add all four angle measures. It should add up to 360.66 + 114 + 114 + 66180 + 114 + 66294 + 66360Yay it worked! FYI: the angles that are across from each other in a parallelogram are always congruent. The sides that are opposite (across from) each other are also congruent. All 4 angles in a parallelogram will add up to 360 degrees. This info will help when you’re solving for the sides or angles of a parallelogram. Good luck!
Stacy spins the pointer 120 times and records the results. The pointer lands 30 times on a section number 2, 19 times on 3, 25 times on 4, 29 times on 5, and 17 times on 6. A winning spin is 2.
Find the the theoretical and experimental probabilities of winning, and compare the 2.
Theoretical Probability:_______
Experimental Probability:__________
Which is greater?:_______
Answer:
Theoretical Probability: 33%
Experimental Probability: 25%
Which is greater?: Theoretical
Step-by-step explanation:
If two out of the six sections are labeled as 2, you'd have a theoretical probability of [tex]\frac{1}{3}[/tex] or 33% of winning.
Based on Stacy's experiment results, the pointer landed on a winning spin 30 out of the 120 times it was spun. This makes the experimental probability [tex]\frac{1}{4}[/tex] or 25% of winning.
In this scenario, the theoretical probability is greater than the experimental probability.

Complete question :
Ryan is mowing lawns. It takes him an hour to mow one lawn. He has already spent 2 hours mowing lawns today. He can only mow today for a total of 5 hours at most. The given inequality can be used to find x, the number of lawns he can still mow today. Which statement is true? A. Ryan can mow no fewer than 7 additional lawns today. B. Ryan can mow no more than 3 additional lawns today. C. Ryan can mow no more than 7 additional lawns today. D. Ryan can mow no fewer than 3 additional lawns today.
Answer:
B. Ryan can mow no more than 3 additional lawns
Step-by-step explanation:
Given that :
Time taken to now 1 lawn = 1 hour = 60 minutes
Number of hours already spent mowing today = 2
He can mow at most 5 hours mowing today
Find the number of lawn x he can still mow today:
Since 1 lawn takes 1 hour to mow ;
Lawns mowed in 2 hours = 2 lawns
The most number of lawn he can mow today Given that he can only spent at most 5 hours mowing will be (5/1) = 5 lawns
Lawns mowed already + x ≤ 5
2 + x ≤ 5
x ≤ 5 - 2
x ≤ 3
Hence, Ryan can mow no more than 3 additional lawns.
