Answer:
27.95 and 34.05 are compatible because when you add up the decimals, the equal 0, which makes it easier to add. 27. 95 + 34.05 = 61.00.
Same with 19.37 and 21.63, it adds up to 40.00
The answer to all of this would be 101.00
Please help i forgot to post the image on the last one
Answer:
x y
0 2
2 6
4 10
6 14
I'll use the second one as the example.
First I found the x value because it was the value gaven to me, then I found the y value that lined up with it. Since the x value was 2, I had to go to the 2 on the x axis and went up until I got to the line, then I went horizontal until I hit the y axis and that's how I got 6 for the y value.
I hope this helped!!

A. x > 32.5 minutes
B. x > 40 minutes
C. x \leq 32.5 minutes
D. x[\leq 40 minutes
Answer: D

81x^4-1 factor with steps
Given:
The expression is
[tex]81x^4-1[/tex]
To find:
The factorized form of given expression.
Solution:
We have,
[tex]81x^4-1[/tex]
It can be rewritten as
[tex]=3^4x^4-1^2[/tex]
[tex]=(3x)^4-1^2[/tex] [tex][\because a^xb^x=(ab)^x][/tex]
[tex]=((3x)^2-1)((3x)^2+1)[/tex] [tex][\because a^2-b^2=(a-b)(a+b)][/tex]
[tex]=(3x+1)(3x-1)(3x+1)(3x-1)[/tex] [tex][\because a^2-b^2=(a-b)(a+b)][/tex]
This is the complete factorized form. It can also written as
[tex]=(3x+1)^2(3x-1)^2[/tex]
Therefore, the complete factorized form is [tex](3x+1)(3x-1)(3x+1)(3x-1)[/tex].

A bag contains 5 milk and 13 dark chocolates.
A sweet is selected at random.
What is the probability of choosing:
P(milk)
=
P(not milk)
=
Answer:P(milk) 5/18 - 27% ----------- P(not milk) 13/18- 73%
Step-by-step explanation:
total chocolates in the bag= 18 (5 milk chocolates + 13 dark chocolates= 18 chocolates in total)
to find percentages divide numerator by denominator ( 5/18 = 27%) (13/18=73%)
P(milk) - 27% chance you will get milk chocolate
P(not milk) 73% chance you will get dark chocolate
It is more likey to get dark chocolate

8 = 4w + 53 + 5w
Step 2: Solve for w
Combine like terms: 8 = 9w + 53Isolate w term: -45 = 9wIsolate w: -5 = wRewrite: w = -5Step 3: Check
Plug in w into the original equation to verify it's a solution.
Substitute in w: 8 = 4(-5) + 53 + 5(-5)Multiply: 8 = -20 + 53 - 25Add: 8 = 33 - 25Subtract: 8 = 8Here we see that 8 does indeed equal 8.
∴ w = -5 is the solution to the equation.
Colette loves to get manicures with her mom. In the past year, however, her mom has had 5 manicures for every 3 Colette has had. If Colette's mom has had 4 more manicures than Colette in the past year, how many manicures has Colette had?
Answer:
Collette had 6 manicures done last year.
Step-by-step explanation:
Since Collette's mom has 67% more manicures than Collette (2 more for every 3), and that difference represented 4 manicures in total, then:
let x be the number of manicures that Collette had during last year.
4 / x = 2/3
2x = 12
x = 6

Joelene goes to bed three hours after dinner. Yesterday, after dinner, she spent 1 ½ hour on her homework and ⅔ of an hour on the telephone. Home much time did she have left before bedtime?
Answer:
50 minutes
Step-by-step explanation:
she spent 1 hr and 30 minutes on homework
she spends 2/3 of an hour on the phone = 40 minutes
1 hr 30 min + 40 minutes = 2 hrs and 10 min
so she had 50 minutes to kill before bedtime since she goes to sleep 3 hrs after dinner
2hr 10 min + 50 min = 3 hrs.
Joe has eaten 2/5 of a pizza.Jane has eaten 1/6 of a pizza how many more pizza has joe eaten than Jane?
Joe ate 7/30 more of pizza than Jane. You can just subtract 2 uneven denominators. So you would turn them into 30 because that’s the closest highest number that can go with 5 and 6. Then multiply 2 with 6 which is 12 and then multiply 1 with 5 which is 5 now you can subtract it. 12/30-5/30=7/30.
Final Result: 7/30

please help with 6-8 ! will give brainliest !! :)
Answer:
6:6=x
7:16=y
8:20=z
Step-by-step explanation:
For 6, since BD is a perpendicuar bisector, that means 15x=90. Divide 90 by 15 and you get 6
for 7, if bd is a angle bisector, you can set 3y=48. divide 48 by 3 and you get 16
for 8, since Bd is a median, you can set 2z-3=z+17. Isolate the variable and you will get 2z-z=17+3. Add like terms together and you get z=20
Just so you know, a perpendicular bisector will make both angles equal to 90, an angle bisector make both angles equal to each other, and medians make it so that it hit a line in the center therefor you can set both sides of the line to be equal

find the slope of the line through each pair of points (6, -10) , (-15 , 15)
[tex]\boxed{\boxed{\pink{\bf \leadsto The \ slope \ of \ the \ line \ is \ \dfrac{-25}{21}.}}}[/tex]
Step-by-step explanation:Two points are given to us and we need to find the slope of the line . The slope of the line passing through points [tex]\bf (x_1,y_1 ) \ \& \ (x_2,y_2) [/tex] is given by ,
[tex]\qquad\boxed{\red{\bf Slope = tan\theta=\dfrac{y_2-y_1}{x_2-x_1}}}[/tex]
Here , the points are ,
( 6 , -10 )( -15 , 15 )[tex]\bf\implies Slope = \dfrac{y_2-y_1}{x_2-x_1} \\\\\bf\implies Slope =\dfrac{15-(-10)}{-15-6} \\\\\bf\implies Slope = \dfrac{15+10}{-21}\\\\\bf\implies Slope =\dfrac{-1(25)}{-1(-21)}\\\\ \bf\implies\boxed{\red{\bf Slope =\dfrac{-25}{21}}}[/tex]

The volume of a cube is increasing at a constant rate of 459 cubic inches per second. At the instant when the volume of the cube is 408 cubic inches, what is the rate of change of the surface area of the cube? Round your answer to three decimal places (if necessary).
Answer:
[tex]\frac{ds}{dt} =31.952[/tex]
Step-by-step explanation:
From the question we are told that
Cube increase rate 459 cubic inches
At 408
Generally the expressions of the is mathematically given to be
[tex]\frac{dv}{dt} =459[/tex]
[tex]\frac{dv}{dt} =3*l^2 \frac{dl}{dt}[/tex]
[tex]v=408[/tex]
Generally
[tex]v=l^3[/tex]
Therefore solving Mathematically
[tex]\frac{dv}{dt} =3*l^2 \frac{dl}{dt}[/tex]
[tex]459 =3*(7.416859539)^2 \frac{dl}{dt}[/tex]
[tex]459 =165.0294163\frac{dl}{dt}[/tex]
[tex]\frac{dl}{dt} =\frac{165.0294163}{459}[/tex]
[tex]\frac{dl}{dt} =0.359[/tex]
Therefore solving mathematically for surface area
[tex]Surface area S=6l^2[/tex]
[tex]\frac{ds}{dt} =6(2l* \frac{dl}{dt})[/tex]
[tex]\frac{ds}{dt} =12l* \frac{dl}{dt}[/tex]
[tex]\frac{ds}{dt} =12*(7.416859539)*0.359[/tex]
[tex]\frac{ds}{dt} =31.95183089[/tex]
[tex]\frac{ds}{dt} =31.952[/tex]

Rewrite the expression as square of a monomial.
0.09a^2
EXTRA POINTS!!!
Answer:
Simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.
0.3
Step-by-step explanation:
Brainliest?
We want to rewrite the given expression as a square of a monomial. We will get:
0.09*a^2 = (0.3*a)^2
So we have the expression:
0.09*a^2
We want to write this as a square of a monomial like:
(c*a)^2 = 0.09*a^2
Basically, we must find a number c such that:
c^2 = 0.09
c = √(0.09) = 0.3
Then the monomial is:
0.3*a
And we can rewrite the given expression as:
(0.3*a)^2

Step-by-step explanation:
15 times 6 equals 90 and 12 times 6 equals 72, the distributive property equation is 90 + 72 in which can be added to 162 as a result.
Hey there!
The formula is: a(b + c) = a(b) + a(c) = ab + ac
“6(15 + 12)”
6(15 + 12)
6(15) + 6(12)
6(15) = 90
6(12) = 72
NEW EQUATION: 90 + 72
