Victor has a goal of making $75 per week at his after-school job. Last month he was within $6.50 of his goal. What are the maximum and minimum amounts that Victor might have made last month?
Answer:
maximum is 81.50
minimum is 68.50
Step-by-step explanation:
1m-751=6.50
m-75=6.50
m=81.50
/m-75=-6.5
m=68.50
The maximum and minimum amounts that Victor might have made last month are $81.5 and $68.5, respectively.
What is Addition?The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.
Given that Victor has a goal of making $75 per week at his after-school job. and Last month he was within $6.50 of his goal. Therefore, the maximum and minimum amounts that Victor might have made last month are,
Maximum and minimum amount = $75 ± $6.50
= $75+$6.50 , $75-$6.50
= $81.5 , $68.5
Hence, the maximum and minimum amounts that Victor might have made last month are $81.5 and $68.5, respectively.

s congruent to . If angle S is (5x-11) degrees and angle U is (4x+9) degrees, find the value of x.
Given:
Consider angle S is congruent to angle U.
The angle S is (5x-11) degrees and angle U is (4x+9) degrees,
To find:
The value of x.
Solution:
Since it is given that angle S is congruent to angle U, therefore the measure of theses two angles are equal because measure of congruent angles are equal.
[tex]m\angle S=m\angle U[/tex]
Put the given values.
[tex]5x-11=4x+9[/tex]
Subtract 4x from both sides.
[tex]5x-4x-11=9[/tex]
Add 11 on both sides.
[tex]x=9+11[/tex]
[tex]x=20[/tex]
Therefore, the value of x is 20.

Which equation is true when the value of x is -6
Answer:
x(4 + 4) + 16 = -32
Step-by-step explanation:
-6 times 4 is -24 so then you add -24 + -24 and get -48. Then if you add a positive 16 to the -48 you get -32.
Manatees are an endangered species of herbivorous, aquatic mammals found primarily in the rivers and estuaries of Florida. As part of its conservation efforts, the Florida Fish and Wildlife Commission records the cause of death for every recovered manatee carcass in its waters. Of the 392392 recorded manatee deaths in 2012, 6868 were perinatal and 8181 were caused by collision with a watercraft. (a) What is the probability that the death of a randomly selected manatee was due to collision with a watercraft? (Enter your answer rounded to four decimal places.)
Answer:
Other question are " (b) What is the probability that the death was not due to collision with a watercraft? (Enter your answer rounded to four decimal places.) P(not collision) - (c) What is the probability that the cause of death was due to perinatal problems or collision with a watercraft? What is the
(c) What is the probability that the cause of death was due to perinatal problems or collision with a watercraft? What is the probability that it was due to some other cause? (Enter your answers rounded to four decimal places.) P(perinatal or collision) P(other cause) -"
a) P(collision) = Number of deaths caused by collision / Total number of deaths
P(collision) = 81/392
P(collision) = 0.2066
b) P(not collision) = 1 - P(collision)
P(not collision) = 1 - 0.2066
P(not collision) = 0.7934
c) P(perinatal or collision) = (68+81)/392
P(perinatal or collision) = 0.3801
P(other cause) = 1 - 0.3801
P(other cause) = 0.6199.

The ratio between the ages of Amar and Kabir is 3:4 at present.after 4 years ago their ages would be 7:9.ratio of ages of Kabir and amar after 20 years from now?
Answer:
[tex]Ratio = 11:13[/tex]
Step-by-step explanation:
Represent Amar age with x
Represent Kabir age with y
So, we have:
Presently
[tex]x : y = 3 : 4[/tex]
After 4 years
[tex]x + 4 : y + 4 = 7 : 9[/tex]
Simplify both ratios:
[tex]x : y = 3 : 4[/tex]
[tex]\frac{x}{y} = \frac{3}{4}[/tex]
Cross Multiply
[tex]4x = 3y[/tex]
Make x the subject
[tex]x = \frac{3}{4}y[/tex]
[tex]x + 4 : y + 4 = 7 : 9[/tex]
[tex]\frac{x + 4}{y + 4} = \frac{7}{9}[/tex]
Cross Multiply
[tex]7(y+4) = 9(x+4)[/tex]
Open Brackets
[tex]7y + 28 = 9x + 36[/tex]
Collect Like Terms
[tex]9x = 7y + 28 - 36[/tex]
[tex]9x = 7y -8[/tex]
Substitute [tex]\frac{3}{4}y[/tex] for x in [tex]9x = 7y -8[/tex]
[tex]9(\frac{3}{4}y) = 7y - 8[/tex]
[tex]\frac{27}{4}y = 7y - 8[/tex]
[tex]6.75y = 7y - 8[/tex]
[tex]6.75y - 7y = - 8[/tex]
[tex]-0.25y = - 8[/tex]
[tex]y = -8/-0.25[/tex]
[tex]y = 32[/tex]
Substitute 32 for y in [tex]x = \frac{3}{4}y[/tex]
[tex]x = \frac{3}{4} * 32[/tex]
[tex]x = \frac{3* 32}{4}[/tex]
[tex]x = \frac{96}{4}[/tex]
[tex]x = 24[/tex]
So, in 20 years time, the ratio of the ages would be:
[tex]x + 20 : y + 20[/tex]
This gives
[tex]24 + 20 : 32 + 20[/tex]
[tex]44 : 52[/tex]
Divide by 4
[tex]44/4:52/4[/tex]
[tex]11:13[/tex]
Hence, the Ratio is
[tex]Ratio = 11:13[/tex]
