Answer:
88%
Step-by-step explanation:
(73+75+84+x)/4=80
x4 to both sides
73+75+84+x=80x4
73+75+84+x=320
232+x=320
x=320-232
x=88
Answer:
88
Step-by-step explanation:
80*4 = 320 320- (73 + 75 +84 ) = 88 we can cross out 320/80 = 32/8 and 232/320 = 232 /4 (320/4) and divide each side by 4 = 58 / 80 then 29/40 = 40-29 = 11 then decimalise /10 = 1.1 then multiply 80 * 1.1 = 88
Find the area of the shape 1/4 of circle radius of 2
Answer:
≈3.14
Step-by-step explanation:
The formula for finding the area of a circle is:
π·r²
π=approximately 3.14(pi)
r=radius
If you follow this formula,
you would multiply 3.14 by 2², which is basically 2x2.
2x2=4 3.14x4=12.56
But since pi is an irrational number that goes on forever, you usually round pi to the hundredths place, which would be 3.14. But since you're finding the area of 1/4 circle, you need to divide the answer by 4. 12.56/4=3.14, so the answer is about 3.14.
The longest amount of time employees can work under Option A or Option B is 20 weeks. After employees work 20 weeks, they can either quit or keep making the same amount they made during Week 20. If an employee plans on quitting after 20 weeks, which payment option gives the greatest total income? Explain
Answer:
to do these word problems, just write equations that reflect the conditions. Once you have the equations, the rest is easy, right? Anyone can solve an equation; the hard part is sorting them out from the words.
So, for #1, we have
A: y = 200 + 50(x-1) = 150+50x
B: y = 200 * 1.10^(x-1)
Now you can easily make a table. See what you can do with the rest of the wowness
Answer:
Option A gives the greatest total income because every week a person keeps working they receive $50 more than the previous week they had worked compared to the $20 more they'd receive with Option B. Option A is also the better option because compared to Option B, the employees would be earning $300 by Week 3 (with Option A) compared to the $260 they'd be earning on the exact same week (with Option B)
Step-by-step explanation:
Employees earn more money working with Option A than with Option B. So, when it comes to quitting on Week 20 they'd have more money with Option A than with Option B.

Help me answer the following pls

Answer:
2 [tex]\frac{2}{9}[/tex]
Step-by-step explanation:
First, we will turn 5 2/5 into an improper fraction:
5 * 5 = 25 + 2 = 27/5
So they worked for 27/5 days.
We want to divide the days worked by the distance to get the unit rate of distance per day:
[tex]\frac{12}{\frac{27}{5} } = \frac{12}{1} * \frac{5}{27}=\frac{60}{27}=\frac{20}{9}[/tex]
So our answer is 2 [tex]\frac{2}{9}[/tex]

9514 1404 393
Answer:
not similar
Step-by-step explanation:
Similar polygons have all corresponding angles congruent, and corresponding sides proportional.
The sides lengths guarantee the polygons are parallelograms, so one pair of angles being congruent is sufficient to ensure that all corresponding angles are congruent.
The ratio of side lengths in the left polygon is 13/8, and the ratio of side lengths in the right polygon is 5.2/2.4 = 13/6. These are different ratios, so the corresponding sides are NOT proportional.
The figures are NOT SIMILAR.

2) the sum of all the angles in the triange is 180, it can be written:

nes a height
A ball is kicked from a height of 2 feet off the ground. After 1 second the ball reaches a height of 22 feet, and it reaches its maximum height of 38 feet after 3 seconds.
• Write the quadratic equation that represents the height of the ball at any given time
• Find the height of the ball at 4 seconds
Solve the following quadratic equations
Answer:
y = - 2x + (1/2 38) + 2 = y = -2x + 19x + 2 at any second and y = -2x^2 / 2 + 19/2 + 2/2 = - x^2 + 19/2 + 2 = - x (4) + 19/2(4) + 1 = -4+ 38 + 1 = 35 seconds
Step-by-step explanation: We see that 38-2ft = 36ft and y intercept = 2 and then -2x allows us to represent the starting point 2 as -2 (1) to allow a descend to our back to 0 for y one we find y intercept we know - x^2 is our simplified equation and an input into this to find the static and slowed descend back to 0 if you keep inputting at 5 and 6 you see the equation speed up Anyway at (4) substitute = 4 seconds we divide our simplified equation a = -x2 into a b c and divide each by 2 before working out the decline of the equation (as equation still represents all ascending and descending) for the 4th second as the height was already said to be at its max at 38 feet see equation in answer to find 4 as substitute for x

IN A CLASS OF 60 STUDENTS, 25 PLAYS BASKETBALL, 2O PLAY VOLLEYBALL, AND 10 STUDENTS PLAY BOTH OF THEM. HOW MANY STUDENTS PLAY NEITHER BASKETBALL NOR VOLLEYBALL?
Answer:
25
Step-by-step explanation:
We'll compare it with the study of sets, the most noticeable operation of which is:
n(A ∪ B) = n(A) + n(B) - n(A ∩ B)where,
n(A ∪ B) is the Union Set, i. e, the set that contains all the elements
n(A) is a subset of the Union Set
n(B) is another subset of the Union Set, and
n(A ∩ B) is the Intersection Set ,i.e, the set contains common elements from both A and B sets.
In the question:n(A ∪ B) = ? (the total number of students in the class who are into the above mentioned sports)Let set A contains the students who play basketball and set B, the students who play Volleyball.
n(A) = 25n(B) = 2010 students play both of them, i. e.,
n(A ∩ B) = 10 (as 10 students have common sports - Volleyball and Basketball)Using the above operation:
=> n(A ∪ B) = n(A) + n(B) - n(A ∩ B)
=> n(A ∪ B) = 25 + 20 - 10
=> n(A ∪ B) = 35
Final Step to the Answer:The total number of students in the class
= students into the given sports + students who don't play any of them
Total number of students in the class is 60Total number fo students playing basketball and volleyball is 35The students who play neither = 60 - 35
= 25

dr.loube, a chemist, mixes two solutions. one is 24% acid ( the rest is water) and the other is 41% acid. about how much of each solution does she need to produce 50 gallons of a solution that is 31% acid?
Using a system of equations, the amount of solution a and b required to make the required gallons of the solution are 29.41 and 20.59 respectively.
Let :
Solution with 24% acid = a Solution with 41% acid = ba + b = 50 - - - - (1)
0.24a + 0.41b = 50 × 0.31
0.24a + 0.41b = 15.5 - - - - (2)
From (1) :
a = 50 - b - - - - (3)
Substituting (3) into (2)
0.24(50 - b) + 0.41b = 15.5
12 - 0.24b + 0.41b = 15.5
0.17b = 15.5 - 12
0.17b = 3.5
b = 20.588
From (3) :
a = 50 - 20.588
a = 29.412
Therefore, about 29.41 gallons of solution a and 20.59 gallons of solution b is required.

On the first day of a family road trip, Kai's family travels 365 miles.
On the third day, they travel 20% farther.
How many miles does Kai's family travel on the third day?
Answer:
438 miles
Step-by-step explanation:
You need to find 120% of 365 because 120% would just be 100% (the starting 365 miles) + the 20% miles on the third day. 120% of 365 would be 438 miles.
