Which of the following is a solution for the inequality 2x < 9?
x = 6
x = 5.5
x = 4.5
x = 4
Answer:
4
Step-by-step explanation:
2×4 is the only one that equals less than 9, 2× 4.5 is 9, 2×5.5 is 11, 2×6 is 12, and the question is trying to get below 9, so 4 is the only answer that can get below 9
Trigonometry. This is an Tangent question.
Answer:
The last option/ 30 degrees
Step-by-step explanation:
we use the pythagorean theoeom to say that the triangle is a right triangle. We know which one the right angle is, so the remaining two angles add up to 90 degrees. we eliminate the third option and the first. Then, eliminate the fourth and the second. The answer is either 42 or 30. It cannot be 42 because 42+56+70=168, and 168 is not equal to 180. So, the answer is 30 degrees.
x=30 degrees
Your friend standing on a 45 foot balcony. He asks you to throw a baseball up to him. You throw a baseball with an initial upward velocity of 50 ft./s. Assuming that you released the baseball 6 feet above the ground, did it reach your friend? Explain.
Vertical motion formula is h = -16t^2 +vt +s where v is initial velocity and s is starting height:
h = -16t^2 + 50t +6
Solving for t: -50/-32 = 1.5625 seconds to reach maximum height.
Now replace t and solve for h ( maximum height)
h = -16(1.5625)^2 +50(1.5625) + 6
h = 45.0625
The value for h is greater than the height of the balcony, so yes the ball reached the friend.

a. 2(14x -6)
b. 3x(13x-6)
c. 2(13x -7)

Step-by-step explanation:
3x-5+23x-9
26x-5-9=26x-14
2(13x-7)
Answer :
C
Step-by-step explanation:
(a+b)(a-b) = a² - b² a( b + c) = ab + ac a (b - c) = ab - ac a( b + c) + d( b + c) = (a + d) (b + c)3x – 5 + 23x – 9 = 26x - 14
2 . 13x = 26x
2. -7 = -14
2 ( 13x -7) so answer is C
or another way :
a. 2(14x -6) = 28x - 12
b. 3x(13x-6) = 39x² - 18x
c. 2(13x -7) = 26x - 14
d. 3x(13x - 5) = 39x² -15x
so answer is C

in danville the library is due south of the courthouse and due wesr of the community swimming pool. if the distance between the library and the countries is 3.9 kilometers and the distance between the courthouse and the city pool is 4.4 kilometers, how far is the library fron the community pool? round to the nearest tenth if necessary. (this is pythagorean theorem btw)
Answer: 2 kilometers.
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the Pythagorean Theorem:
c^2 = a^2 + b^2
Where c is the hypotenuse of the triangle, the longest side (in this case the distance between the courthouse and the city pool) and a and b are the other sides.
Replacing with the values given:
4.4^2 = 3.9^2 + b^2
19.36 = 15.21+b^2
19.36-15.21 = b^2
4.15 = b^2
√4.15 = b
b=2 km

Troy puts $200.00 into an account to use for school expenses. The account earns 7% interest, compounded annually. How much will be in the account after 5 years? Use the formula A=P1+ r n nt, where A is the balance (final amount), P is the principal (starting amount), r is the interest rate expressed as a decimal, n is the number of times per year that the interest is compounded, and t is the time in years. Round your answer to the nearest cent.
Answer:
the final amount is = $280.51
Step-by-step explanation:
The standard formula for compound interest is given as;
A = P(1+r/n)^(nt) .....1
Given that;
Principal P = $200
Interest rate r = 7% = 0.07
Time t = 5 years
Final amount = A
Number of time compounded per year n = 1
Substituting the values;
A = 200(1+0.07/1)^(1×5)
A = 280.51
Therefore, the final amount is = $280.51
An electrician has a piece of wire that is 4 and 3/8 centimeters long. She divides the wire into pieces that are 1 and 2/3 centimeters long. How many pieces does she have?
Answer:
She has approximately 3 pieces ( 2.625)
Step-by-step explanation:
To get the number of pieces, we need to divide the length of the wire by the individual length of the pieces.
To get the division done, it would be easier to convert what we have into improper fractions
For the piece of wire, the length which is 4 and 3/8 centimeters long will be 35/8 centimeters
while;
the individual length of each of the piece which is 1 and 2/3 centimeters long will be 5/3 centimeters
The number of pieces is thus 35/8 divided by 5/3 = 35/8 * 3/5 = 21/8 = 2.625 which is approximately 3 pieces
Dafydd bought a bike for £300 on 1st February 2010. Every year the value of the bike depreciates by 18% of its' value at the start of the year. Find the value of the bike on 1st February 2014.
Answer: £165.41
Step-by-step explanation:
Price of bike when purchased in 2010 = £300
Depreciation rate yearly = 18%
Value of bike in 2011
Purchased price - depreciation value
= £300 - £300 * 0.18
= £300 - £54
= £246
Value of bike in 2012
= 2011 Price - depreciation value
= £246 - £246 * 0.18
= £246 - £44.28
= £201.72
Value of Bike in 2013
= price of 2012 - depreciation value
= £201.72 - £201.72 * 0.18
= £201.72 - £36.31
= £165.41
Price in 2014 would be £165.41

-2.-1
a.

Answer:
x = - 2, x = - 1
Step-by-step explanation:
Given
f(x) = x² + 3x + 2
To find the zeros let f(x) = 0, that is
x² + 3x + 2 = 0
Consider the factors of the constant term (+ 2) which sum to give the coefficient of the x- term (+ 3)
The factors are + 2 and + 1, since
2 × 1 = 2 and 2 + 1 = 3, thus
(x + 2)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x + 1 = 0 ⇒ x = - 1

A) 29.75
B) 10.625
C) 126.4375
D) 21.25
With sides of 12.75 and 17 on the bottom.
Answer:
21.25
Step-by-step explanation:
We can use the Pythagorean theorem since we know the legs
a^2+b^2 = c^2
12.75 ^2 + 17^2 = c^2
162.5625+289= c^2
451.5625 = c^2
Take the square root of each side
sqrt(451.5625) =sqrt( c^2)
21.25 = c

To the nearest cent, how much interest will she earn in 3 years?
Use the formula B = p(1 + r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Answer:
$5180.12
Step-by-step explanation:
B=4000(1+0.09)^3
Answer:
885.1
Step-by-step explanation:
p = 3000
r = 9/100 = 0.09
t = 3 years
B = 3000 * (1+ 0.09)^3
B = 3000 * (1.09)^3
1.09^3 = 1.09*1.09 * 1.09 = 1.295
B = 3000 * 1.295
B = 3885.10
So the interest is Balance - principle = 3885.1 - 3000 = 885.1
