Answer:

100

Step-by-step explanation:

The fraction 2/3 says there are 3 total parts to the track, but Pete only rode 2 of them.

In this type of problem you always multiply the amount of the whole (150) times the fraction of the whole you are calculating (2/3) to get the answer.

150*2 = 300 divided by 3 = 100

Or 150 * (2/3) = 150 * 0.66667 = 100

Answer:lim x- √16-x²=32

Step-by-step explanation:

[tex]x^{4}[/tex]-16

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 ratio between comparable measurements of an item and a representation of that thing is known as a scale factor. The scale factor of the reduction is [tex]\dfrac{1}{4}[/tex].

The ratio between comparable measurements of an item and a representation of that thing is known as a scale factor in arithmetic. The copy will be bigger if the scaling factor is a full number. The duplicate will be smaller if the scaling factor is a fraction.

As it is given that the perimeter of the original figure is 68 feet while the perimeter of the scale drawing is 17 feet. therefore, the scale factor can be written as,

[tex]\rm Scale\ factor = \dfrac{\text{Perimeter of the Scale Drawing}}{\text{Perimeter of the Original Drawing}}[/tex]

[tex]\rm Scale\ factor = \dfrac{17}{68} = \dfrac{1}{4}[/tex]

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

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

Therefore, the median of the given data-set is 20.5

Alternate Interior Angles are formed on the interior of the parallel lines, on the opposite sides of the transverse. The value of x is 14.

When two parallel lines are cut by a transverse. the angles formed on the interior of the parallel lines, on the opposite sides of the transverse are known as the Alternate Interior Angle.

As we can see in the centre where the triangle is formed, the measure of the different angles can be written as,

Vertically opposite Angles, [tex]\angle A = 53^o[/tex]

Alternate Interior Angles, [tex]\angle C = 57^o[/tex]

[tex]\angle B = 5x[/tex]

Now, the sum of all the angles of this triangle can be written as,

[tex]\angle A+\angle B+\angle C = 180^o\\\\53^o + 5x + 57^o = 180^o\\\\110^o + 5x = 180^o\\\\5x = 180^o-110^o\\\\5x = 70^o\\\\x = 14[/tex]

hence, the value of x is 14.

The amount of Canadian dollar that can be exchanged with NC. 45000 is; 533.69 canadian dollar

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

Convert the mixed fraction to an improper fraction

2 1/3= 3*2+1=7/3

Now let’s multiply straight across

5*7/3=5/1 * 7/3=35/3

To get mixed number, divide

Step-by-step explanation:First, based on the data, find the probability of a water cooler being a student's first choice of additions to the lunchroom.

Robert has surveyed 10+7+4+5=26students.

7 of these students ranked a water cooler as their first choice.

So, the probability of a water cooler being a student's first choice of additions to the lunchroom is

26

.

You can estimate how many of the next 50 students surveyed will rank a water cooler as their first choice by assuming that

Theoretical Probability: 33%

Experimental Probability: 25%

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.

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

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!

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.
