Answer: he will have only one cookie left
Step-by-step explanation:
Answer:90
Step-by-step explanation:
let the number of cookies be x
let the number of friends by y
x - 5y = 0
x - 3y = 36
subtract them:
-2y = -36
y = 18
x - 5(18) = 0
x = 90
John has 90 cookies.
The ratio of athletes in the two teams is 3:2. After 12 athletes move from first team to second, the ratio is 5:4. Find the number of athletes on each team originally.
Step-by-step explanation:
Let the athletes be 3x and 2x.
Now, By the question we get,
(3x-12)/(2x+12) = 5/4
or, 12x-48= 10x+60
or, 2x = 108
so, x = 54
now
3x= 3×54= 162
2x = 2×54=108
The number of athletes were 162 in first team and 108 in second team originally.
x is the number of athletes on first team originally ( x > 12, x ∈ Nˣ )
y ----------------------------------------second------------------( y ∈ Nˣ )
The ratio of athletes in the two teams is 3:2
⇒ [tex]\frac{x}{y} =\frac{3}{2}[/tex] (1)
After 12 athletes move from first team to second, the ratio is 5:4
⇒ [tex]\frac{x-12}{y+12} =\frac{5}{4}[/tex] (2)
(1),(2) ⇒ [tex]\left \{ {{\frac{x}{y} =\frac{3}{2}} \atop {\frac{x-12}{y+12} =\frac{5}{4}} \right. <=>\left \{ {{x=162} \atop {y=108}} \right.[/tex]
So: The first team originally has 162 numbers and the second team originally has 108 numbers

A scuba diver descends in the water at a rate of 2312 feet per minute for 2.6 minutes. He immediately changes course when he sees a large fish and ascends at a rate of 28 feet per minute for 2 minutes.
What is the scuba diver's position relative to sea level after the 4.6 minutes?
Enter your answer as a decimal in the box.
ft
2312 FPM for 2.6 minutes
2312 x 2.6 = 6011.2
28 FPM for 2 minutes
28 x 2 = 56
6011.2 descend
55 ascend
0-6011.2 = -6011.2
ans + 56 = -5955.2
:)
Answer:
Descends: 2,312 x 2.6 = - 6,011 (when rounding otherwise known as - 6,011.2, this number is negative because he is descending)
Ascends: 28 x 2 = 56
- 6,011 + 56 = -5,955 (in 4.6 minutes)

Reese has nickels and dimes in his pocket. He counts a total of 11 coins. The total value of his pocket change is 70 cents. Let 'n' represent the number of nickels and let d represent the number of dimes in Reese’s pocket.
Which equations can be used to represent the information in this problem? Check all that apply.
A) 5n + 10d = 11
B) n + d = 11
C) n + d = 70
D) 5n + 10d = 70
E) 10n + 5d = 70
REMEMBER, THIS IS MULTIPLE CHOICE :)
The combine equation that represents the information in this problem is as follows;
n + d = 11
5n + 10d = 70
He has only nickel and dimes in his pocket. The total number of coins is 11 coins. The total cost is 70 cents.
let
n = number of nickels in his pocket
d = number of dimes in his pocket
1 nickel = 5 cents
1 dime = 10 cents
Therefore,
Total number of coins:n + d = 11Total cost of the coins5n + 10d = 70Therefore, the combine equation is as follows:
n + d = 11
5n + 10d = 70

A farmer wants to increase the area of his rectangular pen but keep the pen a rectangular shape. He decides to add 2 1/2 feet of fencing to the width of the pen, but the length will remain 9 1/4 feet. The new area will be 108 3/4 square feet.
Which equation can be used to determine the original width, w, of the pen?
9 1/4(w+2 1/2)=108 3/4
9 1/4w+2 1/2=108 3/4
2 1/2(w+9 1/4)=108 3/4

when keisha installed a fence along the 200 feet perimeter of her rectangular back yard she left and opening for GATE in diagram below she used X to represent the length of the gate (I give brainliest)
Answer:
(x + 60 + 30) * 2 = 200
(x + 90) * 2 = 200 multiply 2 inside parentheses
2x + 180 = 200 move 180 to the other side with changing it's sign
2x = 20 multiply by 2
x = 10 here is the answer
Step-by-step explanation:
Perimeter = (length + width) * 2

Write the equation of the line that passes through the points (8,−7) and (−9,7). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
y + 7 = (-14/17)(x - 8)
Step-by-step explanation:
We want the equation of this line in the point-slope form y - k = m(x - h).
We are given two points (8, -7) and (-9, 7), and may arbitrarily choose one of them to serve as the point (h, k) in the point-slope form shown above. Then the other point is represented by (x, y) in the point slope form shown above:
Let (h, k) be 8, -7) and let (x, y) be (-9, 7). Then, y - k = m(x - h) becomes:
7 - (-7) = m(-9 - 8), so that 14 = m(-17), and the slope is thus m = -14/17
The desired equation is then y + 7 = (-14/17)(x - 8) (which is in point-slope form).
Another way to get this result would be to find m in the usual way:
rise 14
m = ------------- = --------- = -14/17 (same as before).

About 71% of Earth’s surface is covered in water.
Question 1
Part A
If Earth's surface area is about 196,900,000 square miles, about how many square miles are covered in water?
Enter the correct answer in the box.
Part B
About what percent of Earth’s surface is not covered in water? How many square miles is this?
Enter the correct answers in the boxes.
Answer:
A. 139,799,000 square miles
B. 57,101,000 square miles
Step-by-step explanation:
71% ÷ 100 = 0.71
0.71 x 196,900,000 = 139,799,000
100 - 71 = 29
29 ÷ 100 = 0.29
0.29 x 196,900,000 = 57,101,000
another way; knowledge of A
196,900,000 - 139,799,000
= 57,101,000

8.067 ; hundredths Round each decimal to the place indicated.
Answer:
8.06
Step-by-step explanation:
Decimals go in the order 10ths hundredths thousandths ten thousandths and so on. In rounding any decimal, one number gets added to the left if the number is 5 or over and the number is discarded if it is lower than 5.
for example if the number was 1.2345 5 would make 4 5 1.235 then 5woould make 3 4 1.24 but if you want to round to a smaller number the other numbers would not go up the numbers would just be discarded.

The area of a square root is 2.25m2. what is the length of each side of the square?
Show work pls, thank you.
Answer:
1.5 m
Step-by-step explanation:
Area = length * width
or we can say
Area = side1*side2
since they are the same we can say
Area = side * side
which also means area = side^2
so we have the area and we want the side, we need the inverse operation for squaring something. the inverse of squaring something is square rooting
so
sqrt(Area) = side
so
side = sqrt(2.25)
= 1.5 m

"Mathematically" you might have poor education whether it's bad teachers, bad school, or maybe you're just not working hard enough. Maybe you are educated and you're just comparing yourself against smarter people which might make you seem not very educated. Or maybe you're secretly a super genius prodigy and you're just too lazy too show it. Who knows...
