A bag contains a total of 25 marbles. The bag contains white, yellow, and
red marbles. You randomly select one marble from the bag. The probability
that you select a red marble is 16%. How many red marbles are in the bag?
16% * 25 = 4
There are 4 red marbles.
Answer:
4 red marbles
Step-by-step explanation:
25* 0.16 = 4

Identify the y coordinate for the solution to the system of equations. Solve the system using substitution.
y=2x-11
4x + 3y =-13
Answer:
(2,-7)
Step-by-step explanation:
Plug the first equation into the second equation.
4x+3(2x-11)=-13
4x+6x-33=-13
10x=20
x=2
Now, plug the value of x into one of the equations in order to find y.
y=2(2)-11
y=4-11
y=-7
If a rectangle has an area of x^2+x-20 and a width of x-4, what is the length?
Answer:
This (x - 5) represents the length of the rectangle.
Step-by-step explanation:
The formula for the area of a rectangle of length L and width W is A = L * W.
Here, the width is x - 4 and the area is x^2 + x - 20. Dividing the width (x - 4) into the area results in an expression for the length:
x - 4 / x^2 + x - 20
Let's use synthetic division here. It's a little faster than long division.
If the divisor in long division is x - 4, we know immediately that the divisor in synthetic division is 4:
4 / 1 1 -20
4 20
--------------------
1 5 0
This synthetic division results in a remainder of 0. This tells us that 4 (or the corresponding (x - 4) is indeed a root of the polynomial x^2 + x - 20, and so *(x - 4) is a factor. From the coefficients 1 and 5 we can construct the other factor: (x - 5). This (x - 5) represents the length of the rectangle.
Simplify the expression. Write your answer using only positive exponents.

3. The dollar amount d that Megan earns varies directly with the number of
hours h that she works. In her last paycheck, she earned $148.50 working
18 hours. If her next paycheck is $107.25, how many hours did she work?
Answer:
13 hours
Step-by-step explanation:
148.5/18=8.25
107.25/8.25=13
Find the value of x for which (2)^3x = 8^2.
Answer:
x = 2
Step-by-step explanation:
Using the rule of exponents
[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex]
[tex](2)^{3x}[/tex] = [tex]2^{3x}[/tex] and 8 = (2³ )² = [tex]2^{6}[/tex] , so
[tex]2^{3x}[/tex] = [tex]2^{6}[/tex]
Since the bases on both sides are equal, both 2, equate the exponents
3x = 6 ( divide both sides by 3 )
x = 2

Answer: 1/8
Step-by-step explanation: The sample space are all of the different outcomes an event can lead to. The H and T combinations at the bottom are all of the different outcomes. I think the probability of getting 3 tails for the coins (or TTT) is 1/8. This is because there are 24 total outcomes (HHH, HHT, HTH, HTT, THH, THT, TTH, TTT). There is 3/24 TTTs (also, 1/8 if you count the groups/simplify). Therefore, it is 1/8. Hope this helps!

Answer:
The equations which have only one solution is: 5x²+20x+20=0,
Step-by-step explanation:
Answer:
5x^2 + 20x + 20 = 0
12+ 6x +9= 0
Step-by-step explanation:
5x^2 + 20x + 20 = 0 /5 12 + 6x + 9 = 0
x^2 + 4x + 4 = 0 6x = -9-12
(x+2)^2=0 6x = -21
x + 2 = 0 x = -21/6
x=-2 x = -3.5
Simplifique a expressão [5² . 5² . 5³. 125 . 125³ ]³ : [25² . 5² . 5]²
Answer:
5^43
Step-by-step explanation:
[5² . 5² . 5³. 125 . 125³ ]³ : [25² . 5² . 5]² =
= [5² . 5² . 5³. 5³ . (5³)³ ]³ : [(5²)² . 5² . 5]²
= [5² . 5² . 5³. 5³ . 5^9 ]³ : [5^4 . 5² . 5]²
= [5^19]³ : [5^7]²
= 5^57 : 5^14
= 5^43

Answer:
261 km
Step-by-step explanation:
given,s=constant
d1/T1=d2/T2
d1=90km,t1=50 min
d2=? ,t2=(120+25)min
=145min
therefore,d2=(90×145)/50
=261 km

tan Ф = opp/adj in your problem Ф is x
tan x = 4/9
x = arctan (4/9) on your calculator arctan is might look like inverse tan
or you might have to use the 2nd (second) button and then tan
x = inverse tan (0.44444 repeating) try it on your own calculator
