A hawk is sitting on the branch of a tree Question Image ft above the ground. It flies 28.3 ft higher in the air, drops down by 8.2 ft, and then a short time later flies down another Question Image ft onto the branch of another tree. Write an expression that represents the change in the bird’s height. Which of the two branches is higher above the ground?
Please help me asap!
Will mark as Brainliest for first correct answer.
Answer:
if you add 28.3 and 8.2 you will get 36.5
Step-by-step explanation:
Use the function g(x) = 175 + 85x to find
the most number of trees that Jamal can grow
without exceeding $525.
you don't want to exceed 525, so you set the inequality to be
[tex]525\geq 175+85x[/tex]
we can think of the max as just
[tex]525=175+85x[/tex]
solve for x
[tex]85x=350[/tex]
[tex]x=4ish[/tex]
(note: always round down so that you don't exceed the max. ex. you could round to 4.11 instead of 4.12. x=4.12 would give you a value greater than 525)

is this proportional or non proportional ???
Step-by-step explanation:
Non-proportional relationships affect these representations because the y-intercept in the graph will no longer be zero, the ratios in the table will not be proportional, and the equation will be affected because the number will be added or subtracted which is represented by b.
Proportional relationships are relationships between two variables where their ratios are equal. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other.
That constant is know as the "constant of proportionality".

A cake recipe calls for 1.5 cups of milk and 3 cups of flour. Stephen made a mistake and used 7 cups of flour. How many cups of milk should he use to keep the proportions correct?
he should use 3.5 cups of milk.
bc three goes into seven 2 1/3 times.
and 1/3 of 1.5 is 0.5
since 3 goes into 7, 2 times, he uses 3 cups of milk, and sinze 1/3 of 1.5 is 0.5, add them together and you get 3.5

What is the proper expression for the absolute value of 3?
When we take the absolute value of a number, we always end up with a positive number (or zero). Whether the input was positive or negative (or zero), the output is always positive (or zero). For instance, | 3 | = 3, and | –3 | = 3 also.

There are 4 pints of green paint in a gallon bucket. The paint is made from equal amounts of yellow paint and blue paint. To create a different shade of green, the mixture needs to be 80% yellow. How many pints of yellow paint need to be added to the bucket to make the mixture 80% yellow? Brandon says to get that shade of green, 6 pints of yellow paint need to be added to the bucket. Bianca says that won't work. In two or more complete sentences, explain who is correct and why. In your explanation, include the calculations to support the correct answer.
Answer:
Brandon is correct.
Step-by-step explanation:
Initially, there id 4 pints of green paint in the bucket.
As the green paint is made from equal amounts of yellow paint and blue paint, so, the initial amount of yellow and blue paint in the bucket is 2 pint each.
Let x pints of yellow paint to be added to the bucket to make the desired shade.
Total amount of the paint in the bucket, after addition of [tex]x[/tex] pints of yellow color become [tex]4 + x[/tex] pint, in which the ampunt of yellow color is [tex]2+x[/tex] pints.
As, the ampunt of yellow color is 80% of the total amount of the mixture, so
[tex](4+x)\times 80\%=2+x[/tex]
[tex]\Rightarrow (4+x)\times \frac{80}{100}=2+x[/tex]
[tex]\Rightarrow 4(4+x)=5(2+x)[/tex]
[tex]\Rightarrow x=6[/tex]
So, 6 pints of yellow paint to be added to the bucket to make the desired shade.
Hence, Brandon is correct.
Answer:
Brandon is correct that the mixture needs 6 more pints of yellow paint.
50%(4 pints) + 100%(x pints) = 80%(4 + x pints)
2 + x = 3.2 + 0.8x
0.2x = 1.2
x = 6
Bianca is correct because adding the 6 pints won't fit in the gallon bucket. Adding 6 pints of yellow to the original 4 pints of green is 10 pints, which will not fit in the 1-gallon bucket. (1 gallon = 8 pints)

A bacteria colony starts with 5 bacteria at the beginning and triples every hour. How would
you write an explicit equation to model this situation?
A. f(x) = 3.5*
B. f(x) = 3x + 5
C. f(x) = 5x + 3
D. f(x) = 5.3%
Answer:
B. f(x) = 3x + 5
Step-by-step explanation:
Initial amount of bacteria N0 = 5 bacteria's
If the triple every hour,
The increase in bacteria in the colony after x hour will be 3*x =3x
x is the amount of hour.
Total amount of bacteria in the colony after x hour will be N0 + 3x
Let f(x) be the total amount of bacteria in the colony after x hour
f(x) = N0+3x
Since N0 = 5
f(x) = 5+3x
Re-arrange
f(x) = 3x + 5
Hence an explicit formula to model the equation is f(x) = 3x + 5

For questions 1-5, let f(x) = x2 +6x + 7, g(x) = 8x2 – 2, h(x) = 3x + 4, and
k(x) =
x-3
2x+1
1.
Evaluate f(2) - g(2). k(2)
Given expressions;
f(x) = x² + 6x + 7
g(x) = 8x² - 2
h(x) = 3x + 4
k(x) = x - 3
Find f(2) - g(2). k(2)
f(2) = 2² + 6(2) + 7 = 23
g(2) = 8(2)² - 2 = 30
k(2) = 2 - 3 = -1
Now, f(2) - g(2). k(2) = 23 - (30)(-1)
= 53
The solution to the problem is 53

The solution of the given inequalities is y>-3 and y>4 respectively.
What is inequality?When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.
Given inequalities are -3y > 9 and 2y - 6 > 2.
-3y > 9
y > -9 / 3
y > -3
The second inequality will be calculated as,
2y - 6 > 2
2y > 2 + 6
2y > 8
y > 4
Therefore, the solution of the given inequalities is y>-3 and y>4 respectively.

The length y of a rectangle is four less than three times the width x. The perimeter of the rectangle is 16 cm.
Answer:
y = 1 cm
x = 7 cm
Step-by-step explanation:
x = 3y + 4
perimeter = 2 * ( y + x ) = 16
x + y = 8 by using x = 3y + 4
y + 3y + 4 = 8
4y = 4
y = 1
1 + x = 8
x = 7
y = 1 cm
x = 7 cm

Katie has a cat named
Fluffy. Fluffy eats a whole
bag of cat food in two
weeks. Katie feeds Fluffy
twice a day. The cat food
comes in a 7 cup bag.
How many
cups of food
does Fluffy
each serving?
Please show step by step
Answer:
1/2 a cup or 0.5 cups per serving
Step-by-step explanation:
If you were to divide 7 by 14 you would get 0.5. The reason as to why you would divide 7 by 14 is because if she eats twice a day that would be 7 more times then if she were to be fed once a day. So if you were to feed her twice a day that would be 14 times a week.
Don't think this helped at all but I tried my hardest, sorry if you get your problem wrong. Hope you have a good day :D
