Step-by-step explanation:
4/5 gallons for 280 ft² (the ² is missing in the question ...).
3 gallons would be 15/5.
so, what do I need to multiply 4 with to get 15 ?
4×x = 15
x = 15/4
multiplying now also 280 ft² with this factor gives us the answer :
280 × 15/4 = 70 × 15 = 1050 ft²
they can paint 1050 ft² with 3 gallons of paint.

How to solve examples c) d) ?
Factorial sums
Recall the binomial theorem:
[tex]\displaystyle (a+b)^n = \sum_{k=0}^n \binom nk a^{n-k} b^k[/tex]
a. Let a = b = 1 and n = 8. Then the sum above gives the sum shown here,
[tex]\displaystyle \sum_{k=0}^8 \binom8k 1^{n-k} 1^k = \sum_{k=0}^8 \binom8k[/tex]
so it reduces to (1 + 1)⁸ = 2⁸ = 256.
b. Let a = 1 and b = -1 and k = 8. Then by the same argument, the sum reduces to (1 - 1)⁸ = 0.
c. Notice that
[tex]\displaystyle \sum_{j=0}^n \binom n{n-j} = \binom nn + \binom n{n-1} + \binom n{n-2} + \cdots \binom n2 + \binom n1 + \binom n0[/tex]
but this is nearly identical to the sum in part a, with a = b = 1 and arbitrary n, but the order of terms is reversed. Then it reduces to (1 + 1)ⁿ = 2ⁿ.
d. Let a = 1 and b = 2. Then the sum is (1 + 2)ⁿ = 3ⁿ.

Linear or non linear?
Answer:
Linear
Step-by-step explanation:
This is linear because using the data you have provided we can work out that the equation is y= -5x+27
y= mx+ c (c is the gradient)
This equation shows that the line is straight (also shown in the picture) and therefore must make it a linear graph.
For the graph to be non linear, the graph would be curved but this would mean the equation would have to be a quadratic - which it isn't.

Sam started with savings of $2,500 and adds $40 to his savings each week. Marshall started with $7,300 in savings and spends $60 of his savings each week. After how many weeks will both Sam and Marshall have the same amount of savings in their accounts?
The number of weeks it will take both Sam and Marshall to have the same amount of savings in their accounts is 48 weeks
Given:
Amount with Sam = $2,500
Additional savings each week = $40
Amount with Marshal = $7,300
Amount spent each week = $60
let
x = number of weeks
Sam equation:
2500 + 40x
Marshall's equation:
7300 - 60x
Equate both
2500 + 40x = 7300 - 60x
collect like terms
2500 - 7300 = - 60x - 40x
-4800 = -100x
divide both sides by - 100
x = -4800 / -100
x = 48 weeks
Therefore, the number of weeks it will take both Sam and Marshall to have the same amount of savings in their accounts is 48 weeks

A rectangle is inscribed with its base on the x-axis and its upper corners on the parabola
y = 6-x^2
What are the dimensions of such a rectangle with the greatest possible area?
Width =
Height =
Height: 4 units
Width 2√/2
Explanation:
Start by sketching y = 6 - ². Then draw a rectangle beneath it. You will notice that the width is 2x and the height is 6 ². Area is given by length - times width, so the area function will be A=2x (6 - x²) = 12x - 2x³.
Now you differentiate to find the maximum.
A' = 12 - 6x²
Find critical numbers by setting A' to 0.
x = ± √/2
The derivative is negative at x = 2 and positive at x = 1, which justifies that the rectangle with width of √2 has maximal area.
The height will be y (√2) = 6 – (√2)²) = 4

Tessa wants to install a zipline between two trees. The zipline will be strung between the trees at points 42 feet and 3 feet high. Suppose the trees are 60 feet apart. What is the length of the zipline to the nearest tenth of a foot
The length of the zipline is found using Pythagoras's theorem, which gives
the length of the hypotenuse side of a right triangle.
Length of the zipline is approximately 71.56 feetReasons:
Height at which the zipline will be tied to one of the trees = 42 feet
Height at which the zipline will be tied to the other tree = 3 feet
The distance between the trees = 60 feet
Required:
The length of the zipline
Solution:
The length of the zipline is found as follows;
Taking one of the trees to be at the origin, the coordinates of one of the tying point = (0, 42)
The coordinates of the other tying point = (60, 3)
The in the imagined right triangle formed by the zipline and the distance
between the trees, the length of the zipline is given by Pythagoras theorem
as follows;
Length of zipline = [tex]\sqrt{(60 - 0)^2 + (3 - 42)^2} = 3 \cdot \sqrt{569}[/tex] ≈ 71.56
Length of the zipline ≈ 71.56 ft.

Someone help meeee :))
Answer:
Step-by-step explanation:
1) 3x + y = 3
y = -3x + 3
When x = 0 ; y = 0 +3 = 3 (0 , 3)
When x = 1 ; y = -3*1 + 3 = -3 + 3 = 0 (1 , 0)
When x = 2 ; y = -3*2 + 3 = -6 +3 = -3 (2 , -3)
Plot the points (0 ,3 ) ; (1 ,0) and (2 , -3) in the graph and join them
2) y = x + 3
When x = 0 ; y = 0 +3 = 3 (0 , 3)
When x = 1 ; y = 1 + 3 = 4 (1 , 4)
When x = -3 ; y = - 3 + 3 = 0 (-3 , 0)
Plot the points (0,3) , (1, 4) and (-3 , 0) in the graph and join them
3) Plug in (4 , y) int he equation
y = x + 5
y = 4 + 5
y = 9
y = 9
5) 2x + y = 3
At x-intercept y = 0
2x + 0 = 3
2x = 3
x = 3/2
If you roll a fair number cube four times you are more likely to get 2,3,1,6 than 6,6,6,6
Answer:
its is incorrect.
Step-by-step explanation:
Each time you roll the dice, you have a 1 in 6 shot in getting any number. Rolling a 6 does not lower the odds of rolling another 6. Therefore the odds of both of these are (1/6)^4.
This does however change if you are allowed to roll these numbers in any order. In that case, the first batch would be easier.
mark brainliest !!
Answer:
No
Step-by-step explanation:
Every time you roll the dice, there is the same probability of rolling any number (1/6)
Simply compute (1/6)^4, which can also be written as (1/6)*(1/6)*(1/6)*(1/6)
this equals 1/1296.
The probability of rolling any given number is the same, so the probability of rolling any sequence of four numbers is the same.
