Answer:
17
Step-by-step explanation:
In 4z -5y, substitutte 8 for z and 3 for y, obtaining:
4(8) - 5(3) = 32 - 15 = 17
Answer:
17
Step-by-step explanation:
When you have a number by its variable you multiple, if you know the value of the variable then you multiply the two numbers together.
4z-5y
when z=8 and y=3
The equation really is
4 times 8 - 5 times 3
4 times 8 is 32
5 times 3 is 15
15-32
15-32= 17

A recipe for pie dough calls for a ratio of butter to flour of 4/5 : 3 1/3 . If you plan to use 6 2/3 cups of flour, how much butter should you use to keep the same ratio?
Answer:
1 3/5
Step-by-step explanation:
to determine the answer, take the following steps :
determine how much larger the amount of flour you intend to use is more than that indicated in the recipeMultiply the answer gotten in the above step by the amount of flower indicated in the recipe6 2/3 ÷ 3 1/3
20/3 x 3/10 = 2
2 x 4/5 = 8/5 = 1 3/5

Answer:
x > 5/3
Step-by-step explanation:
In general, inequalities are solved the same way that equations are: undo what is done to the variable. (Whatever you do to one side of the inequality, you must also do to the other side.)
If you were to evaluate this inequality for some value of x, you would ...
multiply by 3subtract 5When solving for x, you undo these operations in reverse order. You undo the "subtract 5" by doing "add 5" to both sides of the inequality:
3x -5 +5 > 0 +5
3x > 5
You undo the "multiply by 3" by doing "divide by 3" to both sides of the inequality:
(3x)/3 > 5/3
x > 5/3 . . . . . . . the solution
__
Additional comment
The only difference between solving an equation and solving an inequality is that multiplication or division by a negative number reverses the comparison symbol.
Consider -1 > -2. When this is multiplied by -1, it becomes 1 < 2, with the comparison reversed.
__
As you can see, as long as multiplication and division are with positive numbers, the actual comparison symbol doesn't matter:
3x -5 > 0 ⇒ x > 5/3
3x -5 = 0 ⇒ x = 5/3
3x -5 < 0 ⇒ x < 5/3

What is the perimeter of the rectangle whose vertices are at (6, 3), (−6, 3), (−6, −1), and (6, −1)?
Given:
The vertices of a rectangle are (6, 3), (−6, 3), (−6, −1), and (6, −1).
To find:
The perimeter of the rectangle.
Solution:
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2-(y_2-y_1)^2}[/tex]
Let the vertices of a rectangle are A(6, 3), B(−6, 3), C(−6, −1), and D(6, −1).
Using the distance formula, we get
[tex]AB=\sqrt{(-6-6)^2-(3-3)^2}[/tex]
[tex]AB=\sqrt{(-12)^2-(0)^2}[/tex]
[tex]AB=\sqrt{144}[/tex]
[tex]AB=12[/tex]
Similarly,
[tex]BC=\sqrt{\left(-6-\left(-6\right)\right)^2+\left(-1-3\right)^2}=4[/tex]
[tex]CD=\sqrt{\left(6-\left(-6\right)\right)^2+\left(-1-\left(-1\right)\right)^2}=12[/tex]
[tex]AD\sqrt{\left(6-6\right)^2+\left(-1-3\right)^2}=4[/tex]
Now, the perimeter of the rectangle is:
[tex]Perimeter=AB+BC+CD+AD[/tex]
[tex]Perimeter=12+4+12+4[/tex]
[tex]Perimeter=32[/tex]
Therefore, the perimeter of the rectangle is 32 units.

Answer:
3rd option: The number of protons and neutrons
Step-by-step explanation:
Protons are positively charged
Neutrons are negatively charged
You can easily remember this by the P and N
For an object to be "neutral", the protons and neutrons have to be equal. If they are not equal it will be positively charged of negatively charged.
Martin says that f(x)=2(4)^x starts at 4 and has a constant ratio of 2. What error did Martin make? Explain.
Answer:
A general exponential equation is written as:
f(x) = A*(r)^x
Where:
A is the initial value, this is the value that the function takes when x = 0.
r is the rate of growth
x is the variable.
In this case, the function is:
f(x) = 2*(4)^x
The initial value is:
f(0) = 2*(4)^0 = 2*1 = 2
The initial value is 2.
And the rate of growth is 4.
So Martin seems to mixed these two values (he said initial value = 4, and rate = 2, which is the opposite of what we found)
What is the approximate volume of the cylinder? cylinder with height of 9 feet and radius of 4 feet.
answer choices: 324, 425.16, 734.76, 1,017,36
Answer:
Step-by-step explanation:
Formula
V = pi r^2 h
Givens
H = 9 feet
r = 4 feet
Solution
V = 3.14 * 4^2 * 9
V = 3.14 * 16 * 9
V = 452 square feet. Perhaps that 425 has a reverse digit in it. I'm sure that's the problem.
Write and solve your own multi-step equation that has variables on both sides and at least one fraction.
Example : 5x + 5 + 4x = 4 - 3x + 6 (but dont do this one, do something similar to it and solve it please :) )

You invite your best friend Sheila out for a picnic on Thursday. Sheila tells you "If it rains, there is a 20% probability
that I will come, but if it's sunny, there is an 80% probability that I will come." You check the weather and see that
there is a 40% chance of rain for that day. What is the overall probability that Sheila will attend your picnic? Explain
how you found your answer.
Answer: 56%
Probably that it will rain and she goes + probably that it will be sunny and she goes
= 0.4 * 0.2 + 0.6*0.8
= 0.08 + 0.48
= 0.56
56% chance
In the week leading up to Christmas the galaxy shopping center gives away 6700 candy canes to first 83 children visiting the center each child gets same number of candy canes how maby candy canes does each child get round your answer to nearest tenth
Answer: 80.7
Step-by-step explanation:
From the question, we are informed that in the week leading up to Christmas the galaxy shopping center gives away 6700 candy canes to first 83 children that visits the center and that each child gets same number of candy canes.
If it's shared equally among the children, each child will get:
= 6700 / 83
= 80.7 to the nearest tenth.
can someone please double check this for me?
Answer:
False
True
False
True
Step-by-step explanation:
The 4th option should be correct because the y-intercept on A is greater than the one in B,
A: y = -1/3x + 0 (usually when the y-intercept ain't appearing it means it's 0).
B: y = -1/3 - 2
As we know 0 is greater than -2 because it's closer to being a positive number, so 0 is not positive or negative; 0 is greater than any negative number but smaller than any positive numer so,
0 > -2.
Therefore the last option is true.

Please write eight facts about: The Flow of Energy in a Food Chain.
_________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Answer:
Always linear...
Decreases with successive trophic level
Answer:
Food chains are very important for the survival of most species. When only one element is removed from the food chain it can result in extinction of a species in some cases.An example of a simple food chain would be: A plant grows using the sun's energy and nutrients from the soil. A rabbit eats the plant. A fox eats the rabbit. The fox dies and decomposes into organisms that feed the soil.A producer, which is able to produce its own food, is also called an autotroph. Every species in the ecosystem relies on producers for their existence.A producer is able to covert inorganic compounds into organic compounds. Without this process life could not exist.A producer can use either solar energy or chemical energy to convert organisms into usable compounds.Because the sun is necessary for photosynthesis, life could not exist if the sun disappeared.Consumers can be carnivores (meat eater only), herbivore (plant eater only), omnivore (eats animals and plants), and a scavenger (eats dead animals).Examples of omnivores (plant and animal eaters) are bears (which eat fish, insects, honey, moose, and grass), turtles (which eat crayfish, earthworms, lettuce, and algae), squirrels (which eat seeds, fruit, eggs, and insects), and monkeys (which eat fruit, leaves, and frogs).Examples of carnivores (animal eaters) include hawks, snakes, foxes, and spiders.Examples of herbivores (plant eaters) include rabbits, moose, cows, groundhogs, and grasshoppers.Decomposers, which feed on dead animals, break down the organic compounds into simple nutrients that are returned to the soil. These are the simple nutrients that plants require to create organic compounds.It is estimated that there are more than 100,000 different decomposers in existence.Al-Jahiz was a 9th century scientist who is responsible for introducing the concept of food chains.The food web, which is a concept that expands on the food chain, was introduced in 1927 by Charles Elton.Food chains can be short, or they can be long, depending on how many consumers can be eaten before one dies and begins to decompose.If a food chain were to continue too long, the energy would become less and less and it would not be very valuable to the animal at the end.Step-by-step explanation:
