Answer:
A 23a^2 + 6/12a^2
Step-by-step explanation:
2a+1/3a + 5/4 -2a-3/6a^2
=4(2a+1)+15a/12a - 2a-3/6a^2
=a(8a+4+15a^2)-{2(2a-3)}/12a^2
=8a^2+4a+15a^2-4a+6/12a^2
=23a^2+6/12a^2

2, Jasper withdrew $45.00 from her savings account. She then used her debit card to buy groceries for $30.15, and then deposited a check for $14.65. What was the total amount of change in Jasper’s account?
1. Answer/Step-by-step explanation:
Diving question: 0 - 35.25 + -8.5 = -43.75 below sea level
Baking question: insolvable by lack of information.
2. Answer/Step-by-step explanation:
A money decrease of $60.50 (or -60.50 increase and change)
? - 45 - 30.15 + 14.65 = -60.50
Since we are finding the change it is best to replace the question mark with 0 so that it is easier to solve.
0 - 45 = -45
-45 - 30.15 = -75.25
-75.25 + 14.65 = -60.50
A survey of 2380 golfers showed that 366 of them are left-handed. Find a point estimate for p, the population proportion of golfers that are left-handed.
Answer:
The point estimate is 366/2380
Step-by-step explanation:
Here. we want to find a point estimate for the number of golfers that are left-handed
To get this, we simply divide the number of left-handed golfers by the number of golfers surveyed
Mathematically, this will be 366/2380
3) Given the quadratic equation -x2 +3x -7=0, determine a, b, and c values.
a=

c=
Answer:
a= -1
b= 3
c= -7
The Quadratic Formula uses the "a", "b", and "c" from "ax2 + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the quadratic equation they've given you to solve.

A bag contains 5 cherry, 8 orange, 2 grape, 7 bubblegum, and 3 apple
lollipops. What is the probability of choosing grape for your first lollipop
and orange for your second? (if you ARE replacing it) *
1/75
2/75
10/625
16/625
Answer:
16/625
Step-by-step explanation:
Step one:
sample space
A bag contains
5 cherry,
8 orange,
2 grape,
7 bubblegum, and
3 apple lollipops.
sample size= 5+8+2+7+3= 25
Required:
The probability of choosing grape for your first lollipop
and orange for your second?
1. The probability of choosing the grapes lollipops
=2/25
2. the probability of choosing the orange lollipops----Note in the second choice the sample size will reduce because the first choice was done with out a replacement
=8/24
The total is
2/25*8/25= 16/625

Lizzy has 6.5 hours to tutor 4 students and spend 1.5 hours in a lab. She plans to
tutor each student the same amount of time. The inequality 4t +1.5 < 6.5 can be
used to find t, the greatest amount of time in hours Lizzy could spend with each
student. a. Solve the inequality and interpret what your solution means. b. Can
Lizzy tutor each student for 1.5 hours? Explain. *
Answer:
A. t= 4.1
B. No because t = 4.1 and if you do 6.5 divided by 1.5 then you get 4.3 and that won't work.

PLEASE HELP ME I WILL MARK U AS THE BRAINIEST ANSWER!
Answer:
(21, 8)
(3, 2)
(-15, -4)
Step-by-step explanation:
First we need to create the equation in y=mx +b form.
(m) is slope [rise/run]
(b) is y intercept
The line crosses the y axis at (0,1) so that's our (b) and to find slope we will find a point where ethe line crosses a point, I'll use (0, 1) and see how many it has to go to reach the next point. In this case it has to go up 1, and right 3.
Our slope is 1/3.
y=1/3x+1.
Now we can start applying the given points.
(21, 8)
8=1/3(21)+1
8=7+1
8=8.
(21, 8) is a solution.
(3, 2)
2=1/3(3)+1
2=1+1
2=2
(3, 2) is a solution.
(-15, -4)
-4=1/3(-15)+1
-4=-5+1
-4=-4
(-15, -4) is a solution.
(12, 9)
9=1/3(12)+1
9=4+1
9=5
(12, 9) is not a solution.
(-6, 1)
1=1/3(-6)+1
1=-2+1
1=-1
(-6, 1) is not a solution.
Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

Answer:
measure of angle p=
94
Step-by-step explanation:
ok 5 sided polygon= 540
so put all of those equal to 540
need to find x first
540=132+(4x-10)+(5x-11)+128+(4x+2)
simplify and combine like terms
x=23
now plug in for angle p
(4(23)+2)
94
Find the arc length on a circle with radius =4 inches and central angle of 30°
Answer:
Step-by-step explanation:
I'm assuming you're not doing the pre-calculus version of this equation where your angle is in radians. So we'll do the Geometry version which looks like this:
[tex]AL=\frac{\theta}{360}*2\pi r[/tex]
Our angle is 30 and our radius is 4, so we fill in accordingly:
[tex]AL=\frac{30}{360}*2(3.1415)(4)[/tex] (this is if you multiply in pi. We'll find the answer in terms of pi as well).
AL = [tex]\frac{1}{12}*25.132[/tex] and
AL = 2.09433 inches
In terms of pi, the answer would be
AL = [tex]\frac{2}{3}\pi[/tex] inches
