Solve using pemdas 3 plus 7 times 6 divided by 3
Answer:
17
Step-by-step explanation:
3 + 7 * 6 / 3
PEMDAS says we multiply and add before adding and subtracting so we multiply first (going from left to right)
3 + 42 / 3
Then we divide
3 + 14 = 17

Answer:
Astronomers were trying to find the weight of six planets - Mars, Venus, Pluto, Jupiter, Mercury and Saturn. The number of planets lighter than Mars was equal to the number of planets heavier than Venus. Saturn was heavier than Mars and Mercury was heavier than Pluto. Venus was lighter than Mars. Saturn was not the heaviest planet.

Answer:
1. a=85.8 c=89.2
2. x=29.7 8x=2937. 3
Step-by-step explanation:
2. 8x+x+27°+66°=360°
8x+x=360°-66°-27°
9x=267 >Then divide both sides with 9
x=29,666666...
=8X
=8 (29,66666...)
=237,333...
1. 6X+4X+32°=180°
10X=180°-32
10X=148° >divide both sides with 10
X=14.8
A=6x c=4x+32
=6(14.8) =4(14.8)+32
= 88.8 =91.2

if a + b + c is cast 20 and a + b is equal to 14 , then c is what by process
Answer:
6
Step-by-step explanation:
[tex]a + b + c = 20[/tex]
[tex]a + b = 14(i)[/tex]
Putting value (a + b) in the above equation
[tex]14 + c = 20[/tex]

Solve for v in terms of s, t, and u.
S = U-t + V
V = what??
Answer:
[tex]v=s-u+t[/tex]
Step-by-step explanation:
Hi there!
[tex]s=u-t+v[/tex]
Our goal is to isolate v on one side of the equal sign.
Subtract u from both sides:
[tex]s-u=u-t+v-u\\s-u=-t+v[/tex]
Add t to both sides to isolate v:
[tex]s-u+t=-t+v+t\\s-u+t=v\\v=s-u+t[/tex]

Find the equation of this line. y= [?]x+[?]
Answer:
[tex]y=3x-4[/tex]
Step-by-step explanation:
Hi there!
Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x=0)
1) Determine the slope (m)
[tex]m=\displaystyle\frac{y_2-y_1}{x_2-x_1}[/tex] where two points that fall on the line are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
On the graph, two points are highlighted for us: (0,-4) and (2,2). Plug these into the formula:
[tex]m=\displaystyle\frac{2-(-4)}{2-0}\\\\m=\displaystyle\frac{2+4}{2}\\\\m=\displaystyle\frac{6}{2}\\\\m=3[/tex]
Therefore, the slope of the line is 3. Plug this into [tex]y=mx+b[/tex]:
[tex]y=3x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=3x+b[/tex]
Recall that the y-intercept occurs when x=0. Given the point (0,-4), the y-intercept is therefore -4. Plug this into [tex]y=3x+b[/tex]:
[tex]y=3x+(-4)\\y=3x-4[/tex]

Show that a to the 6th an be written as a perfect square and as a perfect cube.
Answer:
Step-by-step explanation:
a^6 = a * a * a * a * a * a You can break this into groups of 2 and groups of three.
Groups of 3
a^6 = a * a * a * a * a * a
what that means is that you have 2 groups of 3 which can be written as (a^3)^2 which means that this number is a perfect square.
Groups of 2
a^6 = a * a * a * a * a * a
What this means is that you have (a^2)^3 which is three groups of 2 members. The answer is that you have a perfect cube each member of which is a^2
Another strategy for graphing a piecewise function is to use a table of values. The table below has a column for the input values x and for each piece of the function. The shaded cells indicate where the pieces do not define the function for those input values and so you do not need to find those values. You will need to decide which piece is used to define the function when x=3

Step-by-step explanation:

For what values of x is the equation X^2-x=20 true?
Answer: x = 5 or x = -4
Step-by-step explanation:
Given equation
x² - x = 20
Subtract 20 on both sides
x² - x - 20 = 0
Cross factorize the equation
x -5
x 4
Factorize the equation
(x - 5) (x + 4) = 0
[tex]\boxed{x=5}[/tex] or [tex]\boxed{x=-4}[/tex]

Cameron has a bag that contains one silver (S) and one gold (G) marble. The marbles are the same size. Cameron chooses one marble at random and then puts it back in the bag. Then he chooses a second marble. The outcome "GS" means that a gold marble was chosen first and a silver marble was chosen second.
Answer:
(SS,SG,GS,GG) Probability 0.25
Step-by-step explanation:
i don't know how to do this
Heyo!
So, first things first:
Based on the data shown, it appears that Cameron has 1/4 a chance to really recieve any combo of the following. Hence, he can get SS, SG, 6S, GG. So, each chance he picks, he has a 0.25 chance of probably recieving any of the combo. So, the outcome order is (SS, SG, GS, GG) and the probability for each is 0.25.
It hard to really describe how to write it out without an image, but I hope this helps! Pls, lmk if it does! Good luck!
find the endpoint if A (5,-2) and the midpoint is B (3,6), what is C
Answer:
C = (1, 14 )
Step-by-step explanation:
The coordinates of the midpoint are the average of the x and y coordinates of the endpoints.
Find the average of endpoints and equate to coordinates of midpoint
A (5, - 2 ) , let C = (x, y ) , then
[tex]\frac{x+5}{2}[/tex] = 3 ( multiply both sides by 2 )
x + 5 = 6 ( subtract 5 from both sides )
x = 1
and
[tex]\frac{y-2}{2}[/tex] = 6 ( multiply both sides by 2 )
y - 2 = 12 ( add 2 to both sides )
y = 14
Coordinates of C = (1, 14 )

Three liquids are to be mixed in the ratio of 5:3:1 . If ten liters is to be produced, how much of each of the ingredients should be used ?
Answer:
4,320
Step-by-step explanation:
One gallon = 15,140 drips
One liter = 4,000 drips
The ingredients that should be used will be ( 50 / 9 ), ( 5 / 3 ), and ( 10 / 9 ).
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that three liquids are to be mixed in the ratio of 5:3:1.and their total is ten liters. The quantity of each part will be calculated as:-
Let the ratio is L₁ = 5x, L₂ = 3x and L₃ = x.
5x + 3x + x = 10
9x = 10
x = 10 / 9
The fraction of each part will be calculated as:-
5x = 5 x { 10 / 9 ) = 50 / 9
3x = 3 x ( 10 / 9 ) = 10 / 3
x = 10 / 9
Therefore, the ingredients that should be used will be ( 50 / 9 ), ( 5 / 3 ), and ( 10 / 9 ).

A repair bill for a car is $648.45. The parts cost $265.95. The labor cost is $85 per hour. Write and solve an equation to find the number of hours of labor spent repairing the car
Answer:
( t - p ) / 85x = h
( t - 265.95 ) / 85x = h
648.45 - 265.95 / 85x = 3.32h
h = 3.32
Therefore ( t - p ) / 85x = 3.32
Step-by-step explanation:
648.45 - 265.95
282.50 /85
= 3.32 hrs
Finding equation to find hours can be shown as
( t - p ) / 85x = 3.32
How we found equation to find total
Parts = 19 x 14 - 5/100 = 266- 0.05
648.45 - 265.95 = 282.5
282.5/85 = 3.323 near to 3,233529
Labour = 85x = 17 (5 + x)
Equation = 17(5+ x) + 14(19) - 5/100 = 648.45 where x = 85
Equation = ( 85x x 3 1/3) + 265 - 19/20 = t
The repair bill is an illustration of a linear equation. The equation that represents the scenario is: [tex]648.45= 265.95+ 85\times x[/tex]
And the solution (i.e. number of hours) is: 4.5 hours
Given that:
[tex]Bill = 648.45[/tex]
[tex]Parts = 265.95[/tex]
[tex]Labour = \$85[/tex] per hour
Let the number of hours spent be x
So, the equation is:
[tex]Bill = Parts + Labour \times x[/tex]
This gives;
[tex]648.45= 265.95+ 85\times x[/tex]
Collect like terms
[tex]648.45-265.95= 85\times x[/tex]
[tex]382.5= 85\times x[/tex]
Divide both sides by 85
[tex]4.5 =x[/tex]
[tex]x = 4.5[/tex]
Hence, the equation is:
[tex]648.45= 265.95+ 85\times x[/tex]
And the solution (i.e. number of hours) is: 4.5 hours
