Answer:
direct
Step-by-step explanation:
The standard form of an equation representing direct variation is
y = kx ← k is the constant of variation
The standard form of an equation representing inverse variation is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
y = - [tex]\frac{2}{5}[/tex] x ← represents direct variation with k = - [tex]\frac{2}{5}[/tex]
In right triangle GHI, ∠H is a right angle, m∠I=42∘, and GH=11.
sin42∘≈0.67
cos42∘≈0.74
tan42∘≈0.90
What is the measurement of HI?
If necessary, round your answer to two decimal places, like this: 42.53
Answer:
12.22
Step-by-step explanation:
θ = 42°
We solve using Tangent rule of trigonometry.
tan θ = Opposite/Adjacent
GH = Opposite = 11
HI = Adjacent = ?
From the question
tan42∘≈0.90
Hence:
0.90 = 11/HI
HI = 11/0.90
HI = 12.222222222
Approximately = 12.22

John is doing a fundraiser for school. He needs to sell at least $200 worth of items. John is selling shirts for $10 each and hats for $8 each. He must sell more than 12 hats. \ a) Write the system of inequalities that model this situation. Let x represent how many shirts he sells and y represent how many hats he sells.
Answer:
10x + 8y = $200
Where y > 12
Step-by-step explanation:
Let x represent how many shirts he sells
y represent how many hats he sells.
John is doing a fundraiser for school. He needs to sell at least $200 worth of items. John is selling shirts for $10 each and hats for $8 each.
He must sell more than 12 hats.
y > 12
$10 × x + $8×y = $200
10x + 8y = $200
Where y > 12
The system of inequalities that model this situation is :
10x + 8y = $200
Where y > 12
Samuel gave the cashier $30 to pay for 4 bags of candy he was purchasing for a class party. The cashier gave him $2.04 in change. Each bag of candy costs the same amount.
What is the cost in dollars for each bag of candy?
Answer:
Step-by-step explanation:
First, subtract 2.04 by 30
30 - 2.04 = 27.96
Next, divide 27.96 by 4.
27.96/4 = 6.99
Each bag of candy cost $6.99

4(x - 3) + 5 = 17. Given
Given:
The equation is
[tex]4(x-3)+5=17[/tex]
To find:
The solution of given equation.
Solution:
We have,
[tex]4(x-3)+5=17[/tex]
Using distributive property, we get
[tex]4(x)+4(-3)+5=17[/tex]
[tex]4x-12+5=17[/tex]
[tex]4x-7=17[/tex]
Adding 7 on both sides, we get
[tex]4x-7+7=17+7[/tex]
[tex]4x=24[/tex]
Divide both sides by 4.
[tex]x=\dfrac{24}{4}[/tex]
[tex]x=6[/tex]
Therefore, the value of x is 6.

Of the 20 school days last month, there were only 7 when no math or writing homework was
due. There were four days that math and writing homework were both due at the same time.
Math homework was due 7 times total; how many total times was writing due? *
(6 Points)
The value must be a number
Answer:
10
Step-by-step explanation:
The answer is 10 because there are 20 days and no home work is due on 7 of those days so that’s 13 days with homework from math or writing. Then you take the three days where it was just math and subtract that to get 10 days of writing.

how to turn a mixer number to a improper fraction
Step-by-step explanation:
1. keep the demoninator the same
2. to find the numberator, multiply the demoninator number by the whole number, and add the product of that with the numerator number.
example:
2 3/8 = 19/8
1. so, keep the denominator the same, which means that the denominator is 8
2. to find the numerator, you do:
8 times 2 = 16
16 + 3 = 19
--
therefore, the improper fraction of 2 3/8 is 19/8

Answer:
∠A = 90
∠B = 30
∠C = 60
Step-by-step explanation:
Let ∠B = x
∠A = 3x
∠C = x + 30
Angle sum property of triangle: Sum of three angles of triangle is 180
x + 3x + x + 30 = 180 {Combine like terms}
5x + 30 = 180
5x = 180 - 30
5x = 150
x = 130/5
x = 30
∠A = 3*30 = 90
∠C = 30 + 30 = 60
Rachel is sitting in a tree 15 feet above the ground. A minute ago, she spotted a skunk 40 feet from the base of the tree walking closer to her. Now, the skunk is 20 feet from the base of the tree. The diagonal line from Rachel to the skunk is the distance between them. How much closer is the skunk to Rachel now than it was a minute ago?
Given :
Rachel is sitting in a tree 15 feet above the ground.
A minute ago, she spotted a skunk 40 feet from the base of the tree walking closer to her. Now, the skunk is 20 feet from the base of the tree.
The diagonal line from Rachel to the skunk is the distance between them.
To Find :
How much closer is the skunk to Rachel now than it was a minute ago.
Solution :
Initial distance,
[tex]d_i=\sqrt{15^2+40^2}\\\\d_i=42.72\ feet[/tex]
Final distance,
[tex]d_f=\sqrt{15^2+20^2}\\\\d_f=25\ feet[/tex]
Therefore, skunk is ( 42.72 - 25 ) = 17.72 feet closer to Rachel now than it was a minute ago.
Hence, this is the required solution.

Definitely start with outlining one essay, then doing all of your steps, although don't do much re-writing since there may not be enough time. only focus on one at a time though. as for the questions, since it says pre-essay it wants that completed first but unless you have to do it first, i would do it last since the essays are more important.
three numbers have a sum of 112. The first number is twice the second, and the third number is twice the first. What is the smallest of the three numbers?
Answer:
The second number is the smallest of the three numbers with
value n = 16.
Step-by-step explanation:
Let n represent the second number, then the first number is 2n and the third number is 4n.
so
[tex]n+2n+4n=112[/tex]
Solving for n
[tex]n+2n+4n=112[/tex]
[tex]7n=112[/tex]
[tex]\frac{7n}{7}=\frac{112}{7}[/tex]
[tex]n=16[/tex]
As n = 16 is the second number.
The first number = 2n = 2(16) = 32
The third number = 4n = 4(16) = 64
Therefore, the second number is the smallest of the three numbers with value n = 16.

16.Which Three Lengths CANNOT be the lengths of the sides of a triangle?
17.Which Three Lengths COULD-BE the lengths of the sides of a triangle?
Problem 16
Answer: Choice B) 21, 8, 10This is because the two smaller sides 8 and 10 add to 8+10 = 18, but this is not greater than the side 21. For a triangle to be possible, the sum of any two sides must be larger than the third side. I recommend cutting out slips of paper of these lengths to confirm that a triangle is indeed not possible in this case.
=====================================================
Problem 17
Answer: Choice B) 10, 15, 22Choice A is not the answer because 13+8 = 21, but that's not larger than the third side 21.
Choice C is not the answer because 6+11 = 17 which is not larger than 24.
Choice B is the only possible answer. Note we have the three following true inequalities
15+22 > 1010+22 > 1510+15 > 22So adding any two sides of this triangle leads to a sum larger than the third side. We're using the triangle inequality theorem.

If 1/4 fourth is ordered within the list of numbers 2/3 thirds, 1.75 and −0.75, between which two numbers would it be placed?
Answer:
Between -0.75 and 2/3 thirds.
Step-by-step explanation:
Given that:
A list of three numbers.
2/3 thirds, 1.75 and −0.75
Let us convert them all in decimal points.
0.67, 1.75 and -0.75.
Now, let us sort them in the ascending order.
-0.75, 0.67, 1.75
Looking at the given number to be placed: [tex]\frac{1}{4}[/tex] which is equal to 0.25
Now, let us place them on a number line.
We can clearly see that the given number will be between -0.75 and 2/3 thirds.
