Answer:
It will take 22 seconds for the thermometer to hit the ground.
Step-by-step explanation:
A thermometer falls from a weather balloon at a height of 7,744 ft.
This means that the initial height is of 7744ft.
h(t) = -16t2 + initial height
So
[tex]h(t) = -16t^2 + 7744[/tex]
How many seconds will it take for the thermometer to hit the ground?
This is t for which [tex]h(t) = 0[/tex]. So
[tex]0 = -16t^2 + 7744[/tex]
[tex]16t^2 = 0 + 7744[/tex]
[tex]t^2 = \frac{7744}{16}[/tex]
[tex]t = \sqrt{\frac{7744}{16}}[/tex]
[tex]t = 22[/tex]
It will take 22 seconds for the thermometer to hit the ground.

therefore 8is14less than 22How many triangles can be constructed with side lengths of 9.6 cm, 11.6 cm, and 21.2 cm?
0
1
more than one
NEED DIS ANSWER NOW PLZZZ
Answer: A) 0 triangles
============================================================
Explanation:
Adding up the two smaller sides gets us 9.6+11.6 = 21.2, but this result is not larger than the third side of 21.2
For a triangle to be possible, we need to be able to add any two sides and have the sum be larger than the third remaining side. This is the triangle inequality theorem.
I recommend you cutting out slips of paper with these side lengths and trying it out yourself. You'll find that a triangle cannot be formed. The 9.6 cm and the 11.6 cm sides will combine to form a straight line that is 21.2 cm, but a triangle won't form.
As another example of a triangle that can't be formed is a triangle with sides of 3 cm, 5 cm, and 8 cm. The 3 and 5 cm sides add to 3+5 = 8 cm, but this does not exceed the third side. The best we can do is form a straight line but that's not a triangle.
In short, zero triangles can be formed with the given side lengths of 9.6 cm, 11.6 cm, and 21.2 cm
Bob earns $10 per hour plus a

21. Tom buys a DVD player on 12 monthly payments. The cash price is $600. He pays
* 10% deposit and the store charges 9% interest.
(a) How much is each payment?
(b) Total amount Tom pays for the DVD player?
Answer:
Each monthly payment is $ 49.05, and in total Tom paid $ 648.60.
Step-by-step explanation:
Given that Tom buys a DVD player on 12 monthly payments, whose cash price is $ 600, and he pays a 10% deposit and the store charges 9% interest, to determine how much is each payment and the total amount Tom pays for the DVD player the following calculations must be performed:
600 - 600 x 0.1 = 540
540 x 1.09 = 588.6
588.6 / 12 = 49.05
Thus, each monthly payment is $ 49.05, and in total Tom paid $ 648.60.
On a map, 9 cm represents 15 miles. If the distance between two cities on the map is 15 cm, how many miles separate the cities?
Answer:
15 cm on the map is equal to 25 miles.
Step-by-step explanation:
Given that,
On a map, 9 cm represents 15 miles.
The distance between two cities is 15 cm. We need to find the distance in miles.
9 cm = 15 miles
[tex]1\ cm=\dfrac{15}{9}\ \miles[/tex]
So, 15 cm is equal to,
[tex]15\ cm=\dfrac{15}{9}\times 15\ miles\\\\=25\ miles[/tex]
So, 15 cm on the map is equal to 25 miles.

Identify the statements below as sometimes true, always true, or never true.
a. –4<59
b. X< 1
c. -5> -2
d. 3x + 5 = 2
e. 61 = 61
f. -6 < -6
Answer:
Sometimes true: b. d.
Always true: a. e.
Never True: c. f.
Step-by-step explanation:
b. and d. depend on what value you put in, so that is sometimes true. Now a. and e. are always true because it is correct. C. and f. are never true because the equation does not make any sense.

Katie needs 3/4 cup of sugar to make cookies. She only has 1/3 cup. How much more sugar does Katie need?
Answer:
[tex]\frac{5}{12}[/tex] cups
Step-by-step explanation:
This question is asking for the difference between the two values so subtraction is necessary
[tex]\frac{3}{4} -\frac{1}{3}[/tex]
Multiply the top and bottom of the first fraction by 3 and the second one by 4[tex]\frac{3*3}{4*3} -\frac{1*4}{3*4} = \frac{9}{12} -\frac{4}{12}[/tex]
Now just substract
9 - 4 = 5 ==> [tex]\frac{9}{12} -\frac{4}{12} = \frac{5}{12}[/tex]
