You help out at the bowling alley on weekends. One of the arcade games has a bin filled
with stuffed animals. A robotic arm randomly grabs a stuffed animal as a prize for the
player. You are in charge of filling the bin.
You are told that the probability of getting a stuffed giraffe today is 0.4. If there are 28
giraffes in the bin, what is the total number of stuffed animals in the bin?
Answer:
28/0.4,= 28/(2/5)=28*5/2=14*5=70, no need to use calculator
check 70*0.4=28

While traveling in Canada, a police officer pulls you over for speeding. The posted speed limit is 100
km/hr. She asks you if you know how fast you were driving. You suddenly realize that your
speedometer's "100" measures miles/hr, not km/hr. How fast were you going?
Answer:
Speeding at 160.934 km/hr
Step-by-step explanation:
1 mile = 1.609344 kilometers
1.609344 * 100 = 160.934 kilometers
8x+3y=14,2x+y=4. PLz solve this it’s emergency
Answer:
x=1, y=2
Step-by-step explanation:
1) 8x+3y=14 Original system of linear 2d equations
2x+y=4
2) 8x+3y=14
-4 (2x+y) =-4(4) Multiply second equation by negative four.
3) 8x+3y=14
+ -8x-4y=-16 Add equations, eliminating x terms
4) -y=-2
y=2 solve for y
5) 8x+3(2)=14 Substitute solution for y to solve for x
8x=14-6
8x=8
x=1

What is the equation of the graphed line written in standard form?
Answer:
C. y = -2/3x -2
Step-by-step explanation:
We know the slope is negative. You can find slope using rise/run. The y-intercept is -2 because the line meets -2 at the y-intercept.
Answer:
The first answer (top)
Step-by-step explanation:
Standard form is ax+by=c
a and b are the coefficients
Take a point from the given line
I chose (0, -2)
Then, plug in the values of x and y
2*0+3*-2=-6
-6=-6
Since it works the standard form of the line is 2x+3y=-6

Answer:
I think its 183 1/3
It's what I figured out & the other answer says the same.
Step-by-step explanation:
You like TommyInnit, too? Poggers! <3
Answer:
183 1/3
Step-by-step explanation:
I'm assuming that x and y are directly proportional.
So anyways:
5.5 divided by 3/4 is 7 1/3.
Because this is directly proportianol, you'll also have to mutiply y by 7 1/3.
So: 25 times 7 1/3 equal to 183 1/3
Hope this helps!
Can yall help me on this?
Answer:
y = 3x - 2
Step-by-step explanation:
Step 1: Look at the "y" axis and see what it is going through (-2)
Step 2: Check if the line if a positive slope or a negative slope (positive)
Step 3: Since we now know this is a positive slope, it cancels out "D" and "A".
Step 4: This would not be B because the rise is "1" and the run is "3"
Final Ansr: "C" because the rise is "3" and the run is "1" with a "-2" y-intercept.

The y-intercept of a parabola is 1, and its vertex is at (1,0). What function does the graph represent?
A.
f(x) = (x − 1)2
B.
f(x) = (x + 1)2
C.
f(x) = -1(x − 1)2
D.
f(x) = -1(x + 1)2
Answer: A. f(x) = (x - 1)²
Step-by-step explanation:
Tell what number you would add to each side of the inequality to solve the inequality.
f-2 ≤ 3
Add ___ to each side of the inequality
Answer: Add 2 to each side
We do this to undo the "minus 2" or "subtract 2" that is happening to the variable f. Addition is the opposite of subtraction.
Solving that inequality leads to [tex]f \le 5[/tex] meaning f can be 5 or smaller.

Find the value of z. Then find the value of the interior angles
Step-by-step explanation:
[tex] \because \angle JKM [/tex] is the exterior angle of [tex] \triangle KLM [/tex]
[tex] \therefore [/tex] by remote interior angle theorem of a triangle, we have:
[tex] m\angle L + m\angle M = m\angle JKL \\\\
(18z + 3)\degree + (5z - 3)\degree = 161\degree \\\\
(18z + 3+5z - 3)\degree = 161\degree \\\\
(23z)\degree = 161\degree \\\\
23z = 161\\\\
z = \frac{161}{23} \\\\
\huge \red {\boxed {z = 7}} \\\\
\because \measuredangle L = (18z +3)\degree \\\\

\therefore \measuredangle L = (126+3)\degree \\\\
\huge\purple {\boxed {\therefore \measuredangle L = 129\degree}} \\\\
\because \measuredangle M = (5z - 3)\degree \\\\

Step-by-step explanation:
I used my calculators.
There are 14 teams in a basketball league.
Each team plays every other team twice
during the season.
a) Suppose that you want to determine
how many games, in total, are played.
Suggest a simpler problem that you
could solve first.
b) How many games, in total, are played
during the season?
Answer:
Step-by-step explanation:210 games
14+13+12... (x2)
The total number of games played is 182.
What is permutation?The number of possible arrangements for a given set is calculated mathematically using permutation, where the arrangement's order matters.
Given that, there are 14 teams and each team plays twice with the other team.
Since each team plays every other team twice, the total number of games is nothing but the permutation of 2 out of 14 which is given by:
₁₄P₂
=14!/((14-2)!)
= (14×13×12!)/ 12!
= 14×13
=182
Hence, the total number of games played is 182.

−7x + 25 = 48 Step 1: −7x + 25 − 25 = 48 − 25 Step 2: −7x = 23 Step 3: negative seven times x over seven = twenty-three over seven Step 4: x = twenty-three over seven Step 1: He should have added 25 to each side. Step 1: He should have divided both sides by −7. Step 3: He should have divided both sides by −7. Step 3: He should have multiplied both sides by −7.
Answer:
Step 3: He should have divided both sides by −7
Step-by-step explanation:
Incorrect calculation
−7x + 25 = 48
Step 1: −7x + 25 − 25 = 48 − 25 Step 2: −7x = 23
Step 3: negative seven times x over seven = twenty-three over seven
-7*x/7 = 23/7
-7x/7 = 23/7
Step 4: x = twenty-three over seven
Correct calculation
−7x + 25 = 48
Step 1: −7x + 25 − 25 = 48 − 25 Step 2: −7x = 23
Step 3: negative seven times x over seven = twenty-three over seven
-7*x/-7 = 23/-7
-7x/-7 = 23/-7
Step 4: x = twenty-three over negative seven
x = -23/7
Which ordered pairs are NOT a solution of y = 2x + 1? Select all that apply. (3, 7) (3, 7) (0, 1) (0, 1) (-1, 1) (-1, 1) (-3, -5) (-3, -5) (-2, 3)
Answer:
The ordered pairs are;
(-1,1) and (-2,3)
Step-by-step explanation:
Here, we want to select which ordered pair is not a solution to the given equation
The one that will not be a solution will be a point at which if we insert the x-value into the equation, we do not get the y-value at that point
For (3,7
2(3) + 1 = 7
For 0,1
2(0) + 1 = 1
For (-1,1)
= 2(-1) + 1 = -2 + 1 = -1
This is wrong
(-3,-5)
= 2(-3) + 1 = -6 + 1 = -5
(-2,3)
= 2(-2) + 1 = -4 + 1 = -3
This is wrong also
