The area of a hall is 806 sq. ft. Its length is 5 ft greater than its width. Find the dimensions of the hall. Enter the results in the answer box. Show work that leads to the final answer and clearly state the final answer.
Answer:
width is = 26ft
length is = 31ft
Step-by-step explanation:
The area of hall is 806 sq. ft.
length is 5 ft greater than its width.
L = 5+b
L*b = 806
(5+b)*b= 806
5b +b² = 806
B²+5B-806= 0
Solving quadratically
B² +31B -26B -806= 0
B(B+31)-26(B+31)= 0
(B-26)(B+31)= 0
B= 26 or -31
So the value of the width must be positive so the width is = 26ft
If width is 26, length is 26+5 = 31ft

A local hamburger shop sold a combination total of 565 hamburgers and cheeseburgers on Monday there were 65 more cheeseburgers sold than hamburgers how many hamburgers were sold on Monday
Answer:
250
Step-by-step explanation:
I have an easy way of doing this that works for me. Since there are 65 more cheeseburgers, you can subtract 65 from the total number, which leaves you with 500. Then, you just divide that number by 2 and your quotient (250) is the number of hamburgers.
Answer:
250 hamburgers and 315 cheeseburgers
Step-by-step explanation:
565-65=500
then u divide 500 by 2 which =250 hamburgers sold then you add 65 to get the cheeseburgers

What values of x and y satisfy the system of equations {10x+3y=−5−5x−4y=10? (0,−53) (25,−3) (−2,0) (12,−103)
Answer:
The solution of the equation
( 0.4 ,-3)
Step-by-step explanation:
Explanation:-
Step(i):-
Given system of equations
10 x+3 y = −5 ...(i)
- 5 x - 4 y = 10 ...(ii)
Multiply (i) with '5'
10 × 5 x + 3×5 y = - 25
50 x + 15 y = 25 ...(iii)
Multiply (ii) with '10'
-5 × 10 x - 4×1 0 y = 100
- 50 x - 40 y =100 ...(iv)
Step(ii):-
Solving (iii) and (iv)
50 x + 15 y =- 25
- 50 x - 40 y =100
- 25 y = 75
Dividing ' - 25' on both sides, we get
y = -3
substitute y = -3 in equation (i) , we get
10 x+3 y = −5
10 x - 9 = - 5
10 x = -5 + 9
[tex]x = \frac{4}{10}[/tex]
x = 0.4
Final answer:-
The solution of the equation ( 0.4 ,-3)
Points E, F, and D are located on circle C. Circle C is shown. Line segments E C and D F are radii. Lines are drawn from points E and D to point F to form chords E F and D F. Arc E D is 68 degrees. The measure of arc ED is 68°. What is the measure of angle EFD? 34° 68° 112° 132°
Answer:
Option (1). 34°
Step-by-step explanation:
From the figure attached, CE and CD are the radii of the circle C.
Central angle CED formed by the intercepted arc DE = 68°
Since measure of an arc = central angle formed by the intercepted arc
Therefore, m∠CED = 68°
Since m∠EFD = [tex]\frac{1}{2}(m\angle ECD)[/tex] [Central angle of an intercepted arc measure the double of the inscribed angle by the same arc]
Therefore, m∠EFD = [tex]\frac{1}{2}(68)[/tex]
= 34°
Therefore, Option (1) 34° will be the answer.

Find
the most economical car
Solution
The attached spreadsheet shows the costs of repairs, insurance, and gas for each of the cars, using the cost factors described in the problem statement. (Numbers are displayed rounded to dollars.)
Mileage each year is assumed to be 150,000/8 = 18,750.
The "present value" line shows the present (year 0) value of the listed costs. The present value is the sum of values divided by 1.05^(year number). It is calculated using the spreadsheet NPV function.
The green total is the sum of present values to its right and the initial cost. The end value is subtracted after it is discounted by 1.05^8.
The Japanese car has the lowest present value.

A 10-sided fair die, a 20-sided fair die, and a 12-sided fair dice are rolled. What is the probability of all three happening: Showing 8 on the first die Showing either 19 or 20 on the second die Showing an odd number on the third die
Answer:
0.5%
Step-by-step explanation:
The number of faces of each die what it indicates is the total number of events.
On the first die, it has 10 sides and an 8 must come out, that is, 1 event out of 10 possible, therefore the probability is:
1/10
On the second die, which has 20 sides, 19 or 20 can come out, that is 2 events out of 20 possible, so the probability is:
2/20
And on the third die, which is 12 sides, they tell us that an odd number can come out, the odd numbers would be 1, 3, 5, 7, 9, 11; that is, 6 events out of 12 possible, the probability would be:
6/12
Now the final probability would be the product of all:
(1/10) * (2/20) * (6/12) = 0.005
In other words, the probability of this happening is 0.5%

A customer at a bakery paid $78.30 for donuts and cupcakes. Each donut cost $1.95 and each cupcake cost $2.85. If they bought a total of 30 donuts and cupcakes, how many donuts did they buy?
Answer:
[tex] x+y = 30[/tex] (1)
[tex] 1.95x+ 2.85y = 78.30[/tex] (2)
From equation (1) we can solve for x and we got:
[tex] x = 30-y[/tex] (3)
Replacing (3) into (2) we got:
[tex] 1.95(30-y) +2.85 y = 78.30[/tex]
And solving for y we got:
[tex] 58.5 -1.95 y +2.85 y = 78.30[/tex]
[tex] 0.9 y = 19.8[/tex]
[tex] y = 22[/tex]
And then solving for x we got:
[tex] x = 30-22 = 8[/tex]
So then we have 8 donuts and 22 cupcakes
Step-by-step explanation:
Let x the number of donuts and y the number of cupcakes, from the info given we can set up the following equations:
[tex] x+y = 30[/tex] (1)
[tex] 1.95x+ 2.85y = 78.30[/tex] (2)
From equation (1) we can solve for x and we got:
[tex] x = 30-y[/tex] (3)
Replacing (3) into (2) we got:
[tex] 1.95(30-y) +2.85 y = 78.30[/tex]
And solving for y we got:
[tex] 58.5 -1.95 y +2.85 y = 78.30[/tex]
[tex] 0.9 y = 19.8[/tex]
[tex] y = 22[/tex]
And then solving for x we got:
[tex] x = 30-22 = 8[/tex]
So then we have 8 donuts and 22 cupcakes

c) the revenues in the second quarter of a year is approximately 11.69% lower than it would be during the fourth quarter.
d) the revenues in the second quarter of a year is approximately 11.69% lower than the average over all 4 quarters.
Answer:
The correct answer is (b) the revenues in the second quarter of a year is approximately 5.4% lower than it would be during the fourth quarter
Explanation:
Solution:
Given that
Log₁₀ Y = 6.012 + 0.012 X - 0.129 Q₁
= -0.054 Q₂ + 0.098 Q₃
Now,
Given that X =0
We substitute for Q₁ = 1
Thus,
Y = 6.012 + 0.012 (0) - 0.129 (1)
= -0.054 (0) + 0.098 (0)
= 6.012 - 0.129
=5.973
So
Q₂ = 1
Y = 6.102 - 0.054 (1) + 0.012 (0)
= - 0.129 (0) + 0.098 (0)
= 6.012 - 0.054
= 6.048
For Q₃=1
Y = 6.012 + 0.012 (0) - 0.129 (0)
= -0.054 (0) + 0.098 (1)
= 6.102 + 0.098
=6.2

Answer:
MN = 48
Step-by-step explanation:
Since AB is a diameter , so it divides MN into 2 equal parts i.e. MO = NO
7x-4 = 6x
7x-6x = 4
x = 4
Now
MN = MO + NO
MN = 7x-4+6x
MN = 7(4)-4+6(4)
MN = 28-4+24
MN = 48
Answer:
48
Step-by-step explanation:
Since AB is a diameter, MO = NO
7x - 4 = 6x
7x - 6x = 4
= 4
MN = MO + NO
= 7x - 4 + 6x
= 7 * 4 - 4 + (6 * 4)

A circle has a circumference of q and an area of p. Define p in terms of q. Which one is the correct answer?
a. 4q^2π
b. q/2π
c.q^2/π
d. q^2/4π
Answer:
d. q^2/(4π)
Step-by-step explanation:
The circumference in terms of r is ...
q = 2πr
So, the radius in terms of q is ...
r = q/(2π)
The area in terms of radius is ...
p = πr^2
so, in terms of q, it is ...
p = π(q/(2π))^2 = (π/π^2)(q^2/4)
p = q^2/(4π)

A clean air standard requires that vehicle exhaust emissions not exceed specified limits for various pollutants. Many states require that cars be tested annually to be sure they meet these standards. Suppose state regulators double-check a random sample of cars that a suspect repair shop has certified as okay. They will revoke the shop's license if they find significant evidence that the shop is certifying vehicles that do not meet standards.
a. In this context, what is a Type I error?
b. In this context, what is a Type II error?
c. Which type of error would the shop's owner consider more serious? d. Which type of error might environmentalists consider more serious?
Answer:
Step-by-step explanation:
The null hypothesis in this case is: There is significant evidence that the shop is certifying vehicles that do not meet standards so their license gets revoked
a. A type I error in this context occurs if the null is rejected when in actuality, it is true. This means, the shop is certifying vehicles that do not meet standards but their license does not get revoked
b. A type II error in this context occurs if they fail to reject the null when in actuality, it is no true. This means, the shop is not certifying vehicles that do not meet standards but their license does get revoked.
c. Which type of error would the shop's owner consider more serious?
The type II error because it affects the shop owner despite their credibiity
d. Which type of error might environmentalists consider more serious?
The type I error.
