A weather balloon is launched in Texas from an altitude of 240 feet above sea level. If the balloon rises at a constant rate of 65 feet per
minute, which of the following equations could be used to find t, the time in minutes it will take the balloon to reach an altitude of 11,000
feet?
O A. 11,000 = 240t + 65
OB. 11,000 = 240 + 65t
O C. 11,000 = (040 + 65)
D. 11,000 = 65(t + 240)

If m∠ABC = 45° and m∠ECD = 45°, which statement explains whether the AA similarity postulate can be used to determine whether ΔBAC ~ ΔEDC?
answers:
Yes, the AA similarity postulate can be used because a reflection over line f will establish that segment AB ≅ segment DE.
Yes, the AA similarity postulate can be used because a reflection over line f will establish that ∠ABC ≅ ∠DEC.
No, the AA similarity postulate cannot be used because a reflection over line f will establish that segment AB and segment DE are not congruent.
No, the AA similarity postulate cannot be used because a reflection over line f will establish that ∠ABC and ∠DEC are not congruent.
Answer:
B would be the answer
Step-by-step explanation:
If you reflect the triangle ABC onto EDC then you will see that they are congruent and equal.
this means that <ABC ~ <EDC
The AA postulate states that if two corresponding angles of two or more triangles are congruent then the triangles are similar. If you translate ABC onto EDC you can see that all of the angles let alone two are all congruent thus proving that ABC = EDC
Pls mark brainliest if I helped.. Thanks:)
Option (B) is the correct answer.
What is AA postulate?According to the AA postulate, triangles are comparable if two matching angles of two or more triangles are congruent.
Given that,
∠ABC = 45° and ∠ECD = 45°
Angle-Angle or AA similarity postulate,
When triangle ABC reflect onto EDC, then triangle will be congruent and equal.
Implies that ΔABC ≅ ΔDEC.
Hence, option (B) is the correct answer.

Answer:
The x intercepts are (-5, 0) and (2, 0)
The y intercept is (0, -10).
Step-by-step explanation:
The x intercepts are (-5, 0) and (2, 0)
When you set the numbers x + 5 and x - 2 equal to zero, you solve for x and that becomes the x-intercept.
The y intercept is (0, -10).
When you multiply the numbers, you result in [tex]x^{2} +3x - 10[/tex].
Then, set the x values to 0 and evaluate. That leaves you with -10, which is the y-intercept.

Given 4 ordered pairs
The question asks for domain
The domain is the x-value of each ordered pair, and usually it is listed from least to greatest (increasing order)
Take out all of the x-values of the ordered pair 52,72,86,105
Notice that above is already in increasing order, so no further action is needed.
The domain for the situation is {52, 72, 86, 105}

Margaret drank 1/6 of a 36oz. Bottle of soda. She gives the rest of the bottle to her friend Jamie who drinks 2/3 of the soda in the bottle. Jamie then gives the rest of the bottle to her friend Taylor. How much soda is left in the bottle when Taylor gets it? Group of answer choices
Answer:
The amount of soda that is left in the bottle when Taylor get it is 1/6 = 6 oz of soda.
Step-by-step explanation:
Let the total quantity of soda left in the bottle be represented by 1
Total quantity of the bottle = Fraction of what( Margaret + Jamie + Taylor) drank
Margaret drank = 1/6 of the soda
= 1 - 1/6
= 5/6 of soda is left
Jamie drank = 2/3 of what is left
= 5/6 - 2/3
LCM of denominators = 6
= 5 - 4/6
= 1/6
Hence, what is left is 1/6 of the soda.
The size of the soda = 36 oz
1/6 × 36oz
= 6 oz
This means the amount of soda that is left in the bottle when Taylor get it is 6 oz of soda.

A journalist is assigned to write a story that is 1,200 words long. To fit in the publications available space, the story's length can vary by no more than 75 words.
which word counts would be accepted by the journalist's publication?
1,100 1,125 1,290 1,260 1,300
The word count that can be accepted by the journalist's publication is 1,260.
Given,
A journalist is assigned to write a story that is 1,200 words long.
To fit in the publication's available space, the story's length can vary by no more than 75 words.
We need to find which word counts would be accepted by the journalist's publication.
1,100, 1,125, 1,290, 1,260, 1,300
Find the number of words the publication accepts.
We have,
1,200 words long.
The story's length can vary by no more than 75 words.
So,
1,200 + 75 = 1,275 words
The words can vary from 1,200 to 1,275 words.
Find the option which can be accepted.
1,100 - can not be accepted
1,125 - can not be accepted
1,290 - can not be accepted
1,260 - can be accepted
1,300 - can not be accepted
Thus the word count that can be accepted by the journalist's publication is 1,260.

Let f(x)=x²-x-12 and g(x)= x -4.
What value can the expression (f/g)(x) never equal?
Answer:
7
Step-by-step explanation:
This function can never equal 0. Why? well here:
(f/g)(x) also just means [tex]\frac{f(x)}{g(x)}[/tex]. In this case, we get [tex]\frac{x^2-x-12}{x-4}[/tex] Or [tex]\frac{(x+3)(x-4)}{x-4}[/tex]. It seems like you can cancel out x-4 and bam, you get x+3 and any value should work.
However, x can never equal 4 because 4 leads to a case where you divide by 0. This is called discontinuity. Thus, the value you can't get is x=4, or 7 because when you plug 4 in, you get 0/0. Otherwise, any other real value is defined by x+3.

What is the perpendicular slope of the given equation. y=4x-2
The scale on the map is 1 centimeter is equal to 25 kilometers. On the map, the distance the towns along the highway is 4.5 centimeters. Tori's car uses 0.123 liter of gasoline for each kilometer of highway driving. How many liters of gasoline to the nearest liter will Tori need to drive from one of these town to the other?
Answer: About 14 liters of gasoline is required.
Step-by-step explanation:
On the map,
1 centimeter= 25 kilometers.
Distance the towns along the highway is 4.5 centimeters.
Actual distance = 4.5 x 25 km
= 112.5 km
Tori's car uses 0.123 liter of gasoline for each kilometer of highway driving.
Total gasoline required = 0.123 x 112.5 km
= 13.8375 liters≈ 14 liters
hence, about 14 liters of gasoline is required.
