Answer:
2.44706 mph
Step-by-step explanation:
Given that :
Distance = rate * time
Rate of boat + rate of current = 4mph
If rate of current = c ;
Downstream:
85 = 4t
Upstream :
52 = (4 - c)t
85/4 = 52/(4 - c)
85(4 - c) = 52 * 4
340 - 85c = 208
-85c = - 132
c = 132 / 85
c = 1.55294
Rate of boat in still water :
4 - c
4 - 1.55294
= 2.44706 mph

Answer:
1. 144 2. 21
Step-by-step explanation:
1. 12(9 + 3)
Distributive Property is at its finest here. You'll have to multiply 12 with both numbers in the Parthentheses.
1. 12 × 9 = 144
2. 12 × 3 = 36
2. 9 + 12
1. Count up 1 9 times starting at 12 or the opposite.
Solve |3x + 9| + 6 = 6
A) x = 3
B) No solutions
C) x = –3
D) x = 3 or x = –3
Answer:
D
Step-by-step explanation:
3x+9+6=6
step 1 combine like terms
9+6=15
now we have
3x+15=6
step 2 subtract each side by 15
15-15 cancels out
6-15=-9
now we have
3x=-9
step 3 divide each side by 3
3/3 cancels out
-9/3=-3
x=-3
The reason it can also be -3 is because I I means absolute value and the absolute value of negative 3 is positive 3

Answer:
B/ it represents a perfectly linear positive correlation between x and y
Step-by-step explanation:
correlation
of -1.0 indicates a perfect negative correlation, and a correlation of 1.0 indicates a perfect positive correlation.
The correlation coefficient for the data represents a perfectly linear positive correlation between x and y.
What is a perfectly linear positive correlation?It means the variable should be shifted together by having the similar percentage and the direction.
Here it shows the direct relationship between two variables it can be anything like the demand for the product, and the price of the product.
hence, The correlation coefficient for the data represents a perfectly linear positive correlation between x and y.

If we add one unit to the length (l) of a rectangle that has width (w), what is its new area (NA) in terms of its old area (A)?
NA = A + l
NA = A
NA = A + w
NA = A x w
Answer:
NA = A + w is the correct answer
Step-by-step explanation:
just took the quiz :)
Its new area (NA) in terms of its old area (A) is NA = A + w
We have given that,
What is the rea of the rectangleArea=L x W
If we add one unit to the length (l) of a rectangle that has a width (w),
Then we get the area that is
NA = A + w
Therefore option tree is correct.

Mrs. Coote-Brown needed 1 gallon of sliced peaches to make peach pies for her family reunion. If each pie requires 4 cups of peaches, how many pies will Mrs. Coote-Brown be making?
Answer:
Total number of pies make = 4
Step-by-step explanation:
Given - Mrs. Coote-Brown needed 1 gallon of sliced peaches to make
peach pies for her family reunion.
To find - If each pie requires 4 cups of peaches, how many pies will
Mrs. Coote-Brown be making ?
Proof -
As we know 1 gallon = 16 cups.
Now given,
4 cups of peaches = 1 peach pie
⇒1 cup of peach = [tex]\frac{1}{4}[/tex] peach pie
⇒16 cups of peaches = [tex]\frac{16}{4}[/tex] peach pie
⇒1 gallon of peaches = 4 peach pie
∴ we get
Total number of pies make = 4

The diagram shows part of a regular polygon shaded in green.The interior angle is (28x+4)°.The exterior angle is (5x+11)°.How many sides does the polygon have?The diagram is not drawn to scale.
Answer:
10 sides

33x=165°
X=5.
Interior =(28×5)+4=144°
Exterior=(5×5)+11°=36°
