The area of a rectangular field is 5734 m^2.
If the length of the field is 94 m, what is its width?
Answer:
Step-by-step explanation:
Area of rectangle=length x width
Given area= 5734 m^2.
Length=94m
So 5734=94xwidth
width=5734/94=61m is the answer

Answer:
Hope it help, and please give me Brainlest!
Step-by-step explanation:
I just know this one. I'm so sorry!
2x + 13= [tex]\sqrt{x} = 5[/tex]; x + 9 = -4; [tex]4^{3x + 2} = 4[/tex]
The value of x and y in the given figure is 14° and 23° respectively.
What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.
We know vertically opposite angles are equal, and we also know that sum of all the interior angles of a triangle is equal to 180°.
∴ 47° + (2x + 13)° + (5y - 23)° = 180°.
47° + 13° - 23° + 2x + 5y = 180°.
2x + 5y = 143°...(i).
Now, We also know that when parallel lines are intersected by a transversal pair of alternate angles are equal and the sum of two adjacent angles is equal to 180°.
∴ 3x + (5y - 23)° = 180°.
3x + 5y = 157°...(ii)
Now subtracting eqn(i) from eqn(ii) we get x = 14°, and substituting the value of x in any of the equations we y = 23°.

Step-by-step explanation:
the sum of two numbers is 21 . 3/4 of one of the numbers added to 2/3 of the other numbers added to 2/3 of the other gives a sum of 15. find the two numbers
The numbers are 15 and 9 .
Numbers are the basic foundation of mathematics. Numbers are used to represent quantity and used is basic arithmetic operations. Numbers can be categorized into a lot of different types such as real or imaginary. Real numbers can be divided into integers , irrational numbers , whole numbers .The four basic arithmetic operations are multiplication , sum , division and subtraction.
Let us consider one of the given numbers be x .
Given the sum of the numbers is 21
therefore the other number = 21 - x
Now it is given that [tex]\frac{3}{4}[/tex] of 1 number and [tex]\frac{2}{3}[/tex] of another number adds up to 15 .
∴ [tex]\frac{3}{4}[/tex] of x = [tex]\frac{3}{4}x[/tex] and [tex]\frac{2}{3}[/tex] of another number = [tex]\frac{2}{3}\times(21-x)[/tex]
Now the sum of the two new numbers is given as 15.
∴ [tex]\frac{2}{3}\times(21-x) +\frac{3}{4}x =15[/tex]
[tex]or, 14-\frac{2}{3}x +\frac{3}{4}x =15\\\\or, -\frac{2}{3}x +\frac{3}{4}x =15-14\\\\or, \frac{-8+9}{12} x=1\\\\or, \frac{1}{12}x = 1\\\\or, x=12[/tex]
So the other number is 21-12 = 9 .
Hence the two numbers are 15 and 9 .

The ratio of right-handed students to left-handed students is 8 to 3.There are 520 right-handed students in school.How many students are left-handed
Answer:
195 students are left-handed
Step-by-step explanation:
Here, we want to calculate the total number of students who are left-handed
Let the total number of students in the school be x
The total ratio is 8 + 3 = 11
8/11 * x = 520
8x = 11 * 520
x = (11 * 520)/8
x = 715 students
So the number of students who are left handed will be;
Total - number of right-handed students
That would be;
715-520 = 195

Two trains leave Raleigh at the same time one traveling north and the other south the first train travels at 50 miles per hour and the second at 60 miles per hour in how many hours will the trains be in 275 miles apart
Answer:
2.5 hoursStep-by-step explanation:
Step one:
given data
for train one
speed= 50miles per hour
for train two
speed= 60miles per hour
the total distance between both trains=275miles
Step two:
the expression for speed= distance/time
so that, distance= speed*time
let the time be t
we are going to combine both distances
train one distance =50t
train two distance =60t
Hence total distance
50t+60t=275
110t=1=275
t=275/110
t=2.5 hours
It will take 2.5 hours

If his heartbeat has increased by 8 beats per minute after 20 minutes of working out how much will his heartbeat have increased after 30 minutes of working out
Answer:
12 beats per minute after 30minutes
Step-by-step explanation:
Since we are told by how much his heartrate increased in 20 minutes, we can simply calculate how much it increased in 10 minutes and add that amount to the current heart rate to know how much his heartrate increased after 30 minutes of working out. Since 10minutes would be half of the 20minutes we simply divide the beats per minute by 2.
8 / 2 = 4 beats per minute after 10 minutes
Now we simply add this to the beats per minute at the 20minute mark to calculate the beats per minute at 30minutes
8 + 4 = 12 beats per minute after 30minutes

Answer:
A. 127º
Step-by-step explanation:
So we already know that the inside of a triangle is equal to 180º. We already have two of the angles so we can start by adding those together.
75 + 52 = 127
180 - 127 = 53
m∠A = 53º
Now, we also know that a straight line is equal to 180º so all we have to do now is subtract 53 from 180 to get the measure of ∠BAD
180 - 53 = 127
Chicken costs $3.20 per pound, and beef costs $4.59 per pound. Answer each question and show your reasoning. When purchasing 3 pounds, which meat is more expensive? By how much more expensive is it?
Given :
Chicken costs $3.20 per pound, and beef costs $4.59 per pound.
To Find :
When purchasing 3 pounds, which meat is more expensive and by how much.
Solution :
Price of 3 pound chicken, [tex]P_c=3.2\times 3 = \$9.6[/tex] .
Price of 3 pound beef, [tex]P_b = 4.59\times 3=\$13.77[/tex] .
Now, difference in price :
P = $13.77 - $9.6 = $4.17 .
Therefore, beef is more expensive than chicken by $4.17 .
Hence, this is the required solution.
3) The International Space Station takes 644 minutes to orbit Earth 7 times. About how long does each orbit take? I got 92 am I correct to crazy? 100 minutes 95 minutes 90 minutes 80 minutes
Given:
The International Space Station takes 644 minutes to orbit Earth 7 times.
To find:
The time taken by each orbit.
Solution:
Total time = 644 minutes
Total number of orbits =7
Now,
[tex]\text{Time taken be each orbit}=\dfrac{\text{Total time}}{\text{Number of orbits}}[/tex]
[tex]\text{Time taken be each orbit}=\dfrac{644}{7}[/tex]
[tex]\text{Time taken be each orbit}=92[/tex]
So, the required time is 92 minutes.
Therefore, you are correct and all options are incorrect.

Bart wants to rent a car. The fee is $25 plus $0.55 per mile. He has budgeted $212 for the car. Write an
inequality to show how much he can spend for the car.
Answer:
25 + 0.55x ≤ 212
Step-by-step explanation:
Bart can only spend 212, hence the less than or equal to symbol. The cost of using the car must be at most 212, so 25 and 0.55x are on the same side. 0.55x represents the cost of driving an unknown amount of miles.
