Step-by-step explanation:
If DE is the midsegment of ABC what is the value of x AND y?
Answer:
3.) x = 4.5
4.) y = 7
Step-by-step explanation:
3 is an easier one than 4. By the triangle midsegment theorem, the midsegment of a triangle will be half of the base if it is parallel to it. AB is our base, so the equation is like this!
[tex]AB = 2(ED)\\9=2(ED)\\4.5=ED[/tex]
Now for 4, it actually is pretty easy. By the same triangle midsegment theorem, we automatically know that EC and EA are congruent, and CD and DB are also congruent. Meaning y equals 7.
But another way we can determine this (the long, kinda unecessary, but useful way) is through examining the relationship that triangles ABC and EDC have! We know that they are similar triangles by SAS or AA. Meaning, their equation looks something like this...
[tex]4.5(7+y) = 9y\\31.5 + 4.5y = 9y\\31.5=4.5y\\7=y[/tex]
Like I said earlier, 7 is equal to y, but I figured I'd prove it so we are on the same page. Nothing wrong with double-checking ;)

ice cream cost $0.85 per ounce. Which equation best represents y, the total cost of x ounces of ice cream.
Answer:
I'm not sure about my answer but I think it is y=0.85x
Step-by-step explanation:
0.85 is the rate and the rate = the cost of ounces of ice cream which is why 0.85 has an x to it
James has a sidewalk that runs through his flower garden. He needs to put more mulch in the flower garden. If one bag of mulch covers 4 square yards, how many bags of mulch will he need?
Answer:
See Explanation
Step-by-step explanation:
Given
The given proportion can be represented as:
[tex]1\ bag = 4yd^2[/tex]
Required
The additional number of mulch needed
The question has incomplete details, as the amount of mulch he has applied and the area of the flower garden are not given.
So, I will make some assumptions to solve this question.
Let the area of his flower garden be x.
So, we have:
[tex]1\ bag = 4yd^2[/tex]
[tex]y = x\ yd^2[/tex]
Cross multiply
[tex]4yd^2 * y = xyd^2 * 1\ bag[/tex]
Make y the subject
[tex]y = \frac{x\ yd^2 * 1\ bag}{4yd^2}[/tex]
[tex]y = \frac{x* 1\ bag}{4}[/tex]
[tex]y = \frac{x}{4}\ bag[/tex] --- This represents the total amount of mulch required for the flower garden
--------------------------------------------------------------------------------------------------------
Assumptions
Assume that [tex]x = 16[/tex],
So, we have:
[tex]y = \frac{x}{4}\ bag[/tex]
[tex]y = \frac{16}{4}[/tex]
[tex]y = 4[/tex]
i.e 4 bags are needed.
Assume he has applied 2 bags already.
The number of bags needed to apply will be:
[tex]y - 2[/tex]
[tex]y - 2 = 4 - 2[/tex]
[tex]y - 2 = 2[/tex]
2 more bags needed

The product of two numbers is 144, but their sum is -24. What are these two numbers?
Answer:
The two numbers are - 12 and - 12 .
Step-by-step explanation:
Let the two numbers be x and y then
By the question
x * y = 144
or x = 144 / y ....... I)
Again
x + y = - 24
Or 144/y + y = - 24
or, ( 144 + y²) / y = - 24
or, 144 + y² = - 24y
y² + 24y + 144 = 0
y² + ( 12 + 12 ) y + 144 =0
y² + 12y + 12y + 144 = 0
y(y + 12 ) + 12 ( y + 14) = 0
( y + 12 ) ( y + 12 ) = 0
Either
y + 12 =0
y = - 12
Now
x = 144 / - 12 = - 12
Therefore the two numbers are - 12 and - 12 .
Hope it will help :)❤

Answer:
10.29 (rounded = 10.30)
Step-by-step explanation:
X = a^2 + b^2 = c^2
X = 9^2 + 5^2 = c^2
X = (81) + (25) = c^2
X = 106 = c^2
X = √106 = c^2
X = 10.295630141 = c^2
X = 10.03 = c^2 (10.03 is 10.295630141 rounded to the nearest tenth)

a triangle has a 40° angle, a 120° angle and a side 2.5 centimeters in length. which of the following statements are true about the triangle?
Answer:
C
Step-by-step explanation:
A triangle is 180 degrees so 120+40 is 160

Point B has coordinates (4,1). The x-coordinate of point A is -4. The distance between point A and point B is 10 units. What are the possible coordinates of point A?
Given:
Point B has coordinates (4,1).
The x-coordinate of point A is -4.
The distance between point A and point B is 10 units.
To find:
The possible coordinates of point A.
Solution:
Let the y-coordinate of point A be y. Then the two points are A(-4,y) and B(4,1).
Distance formula:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The distance between point A and point B is 10 units.
[tex]\sqrt{(4-(-4))^2+(1-y)^2}=10[/tex]
Taking square on both sides, we get
[tex](8)^2+(1-y)^2=100[/tex]
[tex](1-y)^2=100-64[/tex]
[tex](1-y)^2=36[/tex]
Taking square root on both sides, we get
[tex](1-y)=\pm \sqrt{36}[/tex]
[tex]-y=\pm 6-1[/tex]
[tex]y=1\mp 6[/tex]
[tex]y=1-6[/tex] and [tex]y=1+6[/tex]
[tex]y=-5[/tex] and [tex]y=7[/tex]
Therefore, the possible coordinates of point A are either (-4,-5) or (-4,7).

Simplify the following trigonometric expression. cosθtan²θcotθ
This question requires the understanding of trigonometric identities. I'll list the ones that are needed to answer this question:
cotθ = 1 / tanθ
tanθ = sinθ / cosθ
Look at the latter identity. We can rewrite it as such:
tanθ * cosθ = sinθ
We are given the expression:
cosθ * tan²θ * cotθ
Referring to the first trigonometric identity above, substitute cotθ:
cosθ * tan²θ * (1 / tanθ)
Multiply tan²θ and the fraction:
cosθ * (tan²θ / tanθ)
cosθ * tanθ
Refer to the second trigonometric identity:
cosθ * tanθ
sinθ
cosθ * tan²θ * cotθ = sinθ

Callie brushes her teeth three times each day. She leaves the water running. Is it reasonable to say that she uses 2 cups of water in one day? Explain
Answer: She uses more than 2 cups of water per day.
Step-by-step explanation:
It takes 2 minutes to brush your teeth and if you times that by 3 you get 6 so she spends 6 minuntes per day brushing her teeth and water runs fast. so if your leaving the water on for 6 mintues your filling up much more than 2 cups

Select ALL the expressions that are equivalent to (x^2)(square root of x).
Answer:
x^(2.5) ("x to the power 5/2")
Step-by-step explanation:
(x^2)(√x) can also be written as x·x·x^(1/2). We just add the exponents together: (x^2)(√x) = x^1·x^1·x^(1/2) = x^(2.5) ("x to the power 5/2").
