Answer:
9 pieces
Step-by-step explanation:
first convert 40cm to m by dividing by 100cm
then divide 3.6m by 0.4 then the ans will come.
A) There are 9 strings each of length of 40 cm.
B) 0.20, 5/12, 75% is already in the ascending order.
C) The bearing of Klayton from Lakeshore is also 196°.
In mathematics, it deals with numbers of operations according to the statements.
A) A 3.6 m long string is to be cut into pieces, each of length 40 cm.
3.6 m = 3.6 * 100cm
3.6 m = 360 cm
Let the number of stings be x
x * 40 = 360
x = 360 / 40
x = 9
there are 9 strings each of length of 40 cm.
Arranging the following in ascending order of magnitude: 0.20, 5/12, 75%
0.20, 5/12, 75% is already in the ascending order.
The bearing of Lakeshore from Klayton is 196°. The bearing of Klayton from Lakeshore is also 196°.
Thus, the answers to the given problem are calculated above.

A private university is accepting applications for enrollment. Out of 2,000 applicants, 950 meet the GPA requirements, 600 volunteer for community service, and 250 both meet the GPA requirements and volunteer. Which statement correctly describes the probability that an applicant meets the GPA requirements or volunteers?
The best answer is Because some applicants volunteer and meet the GPA requirements, the events are not mutually exclusive. Thus the probability is 65%.
What is the probability of meeting the GPA requirements or volunteers?The fact that some people could meet both the GPA requirement and the volunteering requirements means that these are not mutually exclusive.
The probability of meeting both would be:
= (Number of people who met either GPA requirements or Volunteer) / Total number of people
= (950 + 600 - 250) / 2,000
= 0.65
= 65%

What is the equation of the following graph in vertex form?
A) y = (x - 1)^2
B) y = (x - 1)^2 + 1
C) y = (x + 1)^2 - 1
D) y = (x + 1)^2
Answer:
D) y = (x+1)^2
Step-by-step explanation:
Given the graph, the y-intercept is 1, and the x-intercept is -1. Only equation that works is D:
When we plug in x=-1:
y=(-1+1)^2
y=0
This is shown on the graph
When we plug in y=1:
1=(x+1)^2
1=x+1
0=x
x=0
This shows up on the graph

Clara is taking a medicine for a common cold. The table below shows the amount of medicine f(t), in mg, that was present in Clara's body after time t:
t (hours) 1 2 3 4 5
f(t) (mg) 236.5 223.73 211.65 200.22 189.41
Heidi was administered 300 mg of the same medicine. The amount of medicine in her body f(t) after time t is shown by the equation below:
f(t) = 300(0.946)t
Which statement best describes the rate at which Clara's and Heidi's bodies eliminated the medicine?
A) Clara's body eliminated the antibiotic faster than Heidi's body.
B) Clara's body eliminated the antibiotic at the same rate as Heidi's body.
C) Clara's body eliminated the antibiotic at half of the rate at which Heidi's body eliminated the antibiotic.
D) Clara's body eliminated the antibiotic at one-fourth of the rate at which Heidi's body eliminated the antibiotic.
Answer: Clara's body eliminated the antibiotic at the same rate as Heidi's body.
Step-by-step explanation:
1) Let's write the data of Clara's table just to have them ready to compare
t (hours) 1 2 3 4 5
f(t) (mg) 236.5 223.73 211.65 200.22 189.41
Change(mg) - -12.77 -12.05 -11.43 -10.81
2) Now calculate the amount of medicine as per Heide's formula, 300(0.946)^t:
t (hours) 1 2 3 4 5
f(t) (mg) 283.8 268.48 253.98 240.26 227.29
Change (mg) -15.12 -14.5 -13.72 -12.97
Now you can compare the data and realize that the rate of change of Heide is greater than the rate of change of Clara, meaning that Heide eliminates the medicine faster than Clara.

Convert the mixed numbers into improper fractions. Convert the improper fraction to mixed Numbers.
Answer:
13) 23/4 14) 13/2 15) 6 1/2 16) 2 7/12
Step-by-step explanation:
13) (4 x 5) + 3 = 23 -> 23/4
14) (2 x 6) + 1 = 13 -> 13/2
15) 13/2 = 6.5, then take the number on the left of the decimal so, 6, as your whole number. After that, multiply it by the denominator so 6 x 2 = 12, then subtract the 12 with the numerator given in the improper fraction so, 13-12 = 1. The answer you get (which is 1 in this case) will be your numerator in for the mixed fraction. -> 6 1/2
Note: the denominator always stays the same
16) 31/12 = 2.58... take the 2 as your whole number.
2(whole number) x 12(denominator) = 24
31 - 24 = 7
= 2 7/12

Step-by-step explanation: To add integers having the same sign, keep the same sign and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.
Step-by-step explanation:
1. (-25)+(+17)=-8

n + 17.22 = 21 what is the answer
Answer:
3.78 because u subtract 17.22 from 21
Answer: Please make your question clearer next time.
n= 3.78
Step-by-step Explanation:
Subtract 17.22 from both sides of the equation.
n + 17.22=22
n + 17.22 - 17.22 = 21 - 17.22
Simplify: 21 - 17.22= 3.78, Therefore n= 3.78.

WILL GIVE BRAINLIEST !!!! A fence borders a triangular shaped field. A scale drawing of the fence is shown. The scale of the drawing to the actual size of the field is 24mm: 5m
SELECT MUTIPLE CHOICE !
Answer:
12.5 m
17.5 m
20 m
Step-by-step explanation:
Scale of the drawing to the actual size of the field = 24 mm : 5 m
✍️Given an actual length of 96 mm, actual length would be x m.
Thus:
24 mm : 5 m = 96 mm : x m
[tex] \frac{24}{5} = \frac{96}{x} [/tex]
Cross multiply
[tex] 24x = 96*5 [/tex]
[tex] 24x = 480 [/tex]
Divide both sides by 24
[tex] x = \frac{480}{24} [/tex]
✅[tex] x = 20 m [/tex]
✍️Given an actual length of 84 mm, actual length would be x m.
Thus:
24 mm : 5 m = 84 mm : x m
[tex] \frac{24}{5} = \frac{84}{x} [/tex]
Cross multiply
[tex] 24x = 84*5 [/tex]
[tex] 24x = 420 [/tex]
Divide both sides by 24
[tex] x = \frac{420}{24} [/tex]
✅[tex] x = 17.5 m [/tex]
✍️Given an actual length of 60 mm, actual length would be x m.
Thus:
24 mm : 5 m = 60 mm : x m
[tex] \frac{24}{5} = \frac{60}{x} [/tex]
Cross multiply
[tex] 24x = 60*5 [/tex]
[tex] 24x = 300 [/tex]
Divide both sides by 24
[tex] x = \frac{300}{24} [/tex]
✅[tex] x = 12.5 m [/tex]
What are the coordinates of point Q? On a coordinate plane, point Q is 4 units to the right and 2.5 units up. (Negative 4, 2 and one-half) (Negative 2 and one-half, 4) (2 and one-half, 4) (4, 2 and one-half)
Answer:
(4, 2 and one-half)
Step-by-step explanation:
Since, point Q is 4 units to the right and 2.5 units up. Both the coordinates of point Q are positive.
Therefore, Q = (4, 2 and one-half)
The coordinates of point Q will be Q(4, 2.5).
What are coordinates?The coordinates in rectangular cartesian system are of the form -
(x, y)
where -
{x} - distance along x - axis.
{y} - distance along y - axis.
Given is the point Q.
It is given that point Q is 4 units to the right and 2.5 units up. So, the coordinates of point P, will be (4, 2.5).
Therefore, the coordinates of point Q will be Q(4, 2.5).
