Answer:
1/105
Step-by-step explanation:
First, the probability that Joe chooses a grand prize bag is 2/15 because there are 2 grand prize bags out of 15 total bags.
Next, the probability that Devon chooses a grand prize bag is 1/14 because if Joe already chose one of the grand prize bags, there is only 1 left out of a total of 14 bags left.
The last step is to multiply those two bags, so [tex]\frac{2}{15} * \frac{1}{14}[/tex] = [tex]\frac{1}{105}[/tex]
Help pls!! Find the value of x and m
Answer:
The answer's the third one listed.
Step-by-step explanation:
The equation to solve for x is:
6x + 16 + 10x - 6 + 90 = 180
16x + 100 = 180
16x = 80
x = 5
To solve for angle BCD, just substitute 5 for x
m = 10(5) - 6
m = 50 - 6
m = 44

Which graph represents f(x) and the inverse f^-1(x)
Answer:
D
Step-by-step explanation:
The inverse or f⁻¹(x) of a function f(x) is the graph being reflected over the line y = x.
For A, f(x) is reflected over the x-axis.
For B, f(x) is rotated about a point.
For C, f(x) reflected over the y-axis.
And for D, f(x) is reflected over the line y = x.
So, the graph that represents f(x) and its inverse f⁻¹(x) is choice D.
please help me i need to turn in assignment!!!!! i will mark the answer brainliest. plz be descriptive!!!
Answer: D. 150
Step-by-step explanation:
Given equation: [tex]3(3x-10)=5(x+10)[/tex] , it shows the relationship between the perimeter of an equilateral triangle and the perimeter of an equilateral triangle.
Consider [tex]3(3x-10)=5(x+10)[/tex]
[tex]\Rightarrow\ 9x-30=5x+50\\\\\Rightarrow\ 9x-5x= 50+30\\\\\Rightarrow\ 4x= 80\\\\\Rightarrow\ x=\dfrac{80}{4}\\\\\Rightarrow\ x= 20[/tex]
Now, perimeter of pentagon = 5(x+10) = 5 (20+10)
= 5(30) = 150
Hence, option D is correct.

The Perimeter of the scalene triangle is 54.6cm
Which equation can be
used to find the value of b if side a measures 8.7 cm?
a 8.7+b=54.6
b 17.4+ b = 54.6
c 26.1 + b = 54.6
d 34.8+b =54.6
Answer: B. 17.4+b=54.6
Step-by-step explanation:
Edgen 2023
The equation can be used to find the value of b is 54.6 = 34.8 + b.
We have,
The border of the triangle is54.6 cm
and side a = 8.7 cm,
So, Perimeter = sum of the lengths of the three sides
54.6 = a + 3a + b
54.6 = 4a + b
We know a= 8.7 then
54.6 = 4(8.7) + b
54.6 = 34.8 + b
Therefore, the needed equation is54.6 = 34.8b.

4. The length of a rectangle is one more than twice the width. The area is 105 in?.
Find the WIDTH of the rectangle. *
9514 1404 393
Answer:
7 in
Step-by-step explanation:
For width w in inches, the length is given as 2w+1. The area is the product of length and width, so we have ...
A = LW
105 = (2w +1)w
2w^2 +w -105 = 0
To factor this, we're looking for factors of -210 that have a difference of 1.
-210 = -1(210) = -2(105) = -3(70) = -5(42) = -6(35) = -7(30) = -10(21) = -14(15)
So, the factorization is ...
(2w +15)(w -7) = 0
Solutions are values of w that make the factors zero:
w = -15/2, +7 . . . . . negative dimensions are irrelevant
The width of the rectangle is 7 inches.
(I BEG U TUTORS HELP) the value if x=9 a solution to the system of equations shown below. Where b is some unknown constant. Determine the value of b. Show how you arrived at your answer
y=2x-20
y= -5x+b
Answer:
b = 43
Step-by-step explanation:
So let's plug things in first:
y= 2x - 20 and y= -5x +b which can become →
2x - 20 = -5x + b (now you said that x=9 so let's plug that in)
2(9) -20 = -5(9) + b (now try solving that)
18 -20 = -45 + b → -2 = -45 + b ( so then add 45 to both sides)
43 = b ( and there's your answer )

Points A and C are vertices of a cube with a side length of 2 cm, and B is the point of the intersection of the diagonals of one face of the cube, as shown below.
Determine the length of CB.
9514 1404 393
Answer:
CB = √6 cm
Step-by-step explanation:
The diagonal of a square is √2 times the edge length, so the length AB will be (1/2)√2(2 cm) = √2 cm.
Then the length CB is given by the Pythagorean theorem as ...
CB = √(AC^2 +AB^2) = √((2 cm)^2 + (√2 cm)^2) = √(4 +2) cm
CB = √6 cm

Lisa sold 1 roll of plain wrapping paper and 3 rolls of holiday wrapping paper for a total of $58. Find the cost each of one roll of plain wrapping paper and one roll of holiday wrapping paper
Answer:
P = 4 & H = 18
Step-by-step explanation:
Daniel : 5 plain paper + 3 holiday paper = 74, 5P + 3H = 74 . Lisa : 1 plain paper + 3 holiday paper = 58, P + 3H = 58 . Solving two equations, P = 4 & H = 18

5(4x-10)+10x = 4(2x-3)+ 2(x-4)? is equal to - 7/4 or - 1/4 or 3/20 or 3/2 ?
Answer:
x is equal to 3/2
Step-by-step explanation:
Let's solve it!
5(4x - 10) + 10x = 4(2x - 3) + 2(x - 4)
expand:
20x - 50 + 10x = 8x - 12 + 2x - 8
group like terms:
30x - 50 = 10x - 20
factor out common multiples:
3x - 5 = x - 2
group terms again:
3x - x = -2 + 5
2x = 3
and divide both sides by two:
x = 3/2
Substitute y=-2x+5 into 2y=2x-8 and solve for x
(help me asap please)!!
Answer:
x = 3
Step-by-step explanation:
2y = 2x - 8
2(-2x + 5) = 2x -8
-4x + 10 = 2x - 8
+4x +4x
10 = 6x - 8
+8 +8
18 = 6x
divide both sides by 6
x = 3
