Complete the equation for the relationship, where y is the actual length in feet, and x is the blueprint
length in inches.y =
The length of a wall on the blueprint is 9 inches. Find the actual length of the wall.
The actual wall is
feet long.
A window in the room has an actual width of 1.5 feet. Find the width of the window in the blueprint.
The width of the window in the blueprint is
in.
Answer:
13.5 feets
1 inch
Step-by-step explanation:
Given :
Blueprint length (in.) __2 4 6 8 10 12
Actual length (ft) _____3 6 9 12 15 18
From the data:
Blueprint : actual
2 in : 3 feets
Length of wall on blueprint = 9 inches
Actual length of wall :
2 inches = 3feets
9 inches = x
Cross multiply
2x = 27
x = 27 /2
x = 13.5 feets
B.)
For actual width = 1.5 feets
2 inches = 3feets
x = 1.5 feets
3x = 2 * 1.5
3x = 3
x = 3/3
x = 1 inch
anyone please help with this please
Choice 2) 44
From definition of a parallelogram, the opposites are equal. Therefore we can conclude that 4x+28=10x+4, then solve.
6x=24
x=4
RS=10x+4=10*4+4=44
Answer is 44. Done!

How many grams are contained in 9.0mol Al2O3. Show work
Answer:
[tex]\boxed{\color{blue}\textsf{The weight of the Aluminium oxide is \textbf{900 grams . }}}[/tex]
Step-by-step explanation:
Here we are given 9 moles of [tex]\sf Al_2O_3[/tex] and we need to find its weight in grams . So we know the formula to find the number of moles as ,
[tex]\qquad\boxed{ \sf N_{(moles)}= \dfrac{Weight(in \ grams )}{Molecular \ weight }}[/tex]
Now the molecular mass of [tex]\sf Al_2O_3[/tex] is , equal to 26*2 + 16*3 = 52 + 48 = 100 g
Using the formula to find the Number of moles :-
[tex]\sf\implies \sf N_{(moles)}= \dfrac{Weight(in \ grams )}{Molecular \ weight } \\\\\sf\implies 9 =\dfrac{ W}{ 100g }\\\\\sf\implies W = 9 \times 100 g \\\\\sf\implies\boxed{\pink{\frak {Weight_{(Al_2O_3)}= 900 grams }}}[/tex]

If you want to buy an item in a store that costs $24 and is on sale for 30% off, then how much would the item actually cost you after the discount? Round to the nearest cent.
Answer: $16.80
Step-by-step explanation:
First you need to find 30% of 24. You can do this by doing .30*24. Then you get 7.2. Now you know what 30% of 24 is, so you subtract it from 24 since it is a discount. So -> 24 - 7.2 = $16.80.
Hope this helped!

show that line passing through points (3,-2) and (-4,-2) is a horizontal line
Step-by-step explanation:
horizontal lines will have a gradient(m) of 0
so if m=0 , the line is horizontal
formula to find m:
m=y2-y1 / x2-x1
insert coordinates into formula
[tex]m = \frac{ - 2 - ( - 2)}{ - 4 - 3} \\ \\ m = \frac{ - 2 + 2}{ - 7} \\ m = \frac{0}{ - 7} \\ m = 0[/tex]
As m=0 , therefore it is a horizonta line.

There are 3 seventh- grade boys,4 seventh-grade girls, 5 eighth grade boys, and 8 eight grade girls that have parts in the school play. One cast member will have the responsibility of introducing the play. That cast member will be chosen randomly. What is the probability that the student introducing the play will be a boy?
Answer:
40%
Step-by-step explanation: 3 + 5 = 8 boys total 4 + 8 = 12 girls total 8 + 12 = 20 kids total. To find out the probability of randomly choosing a boy you have to do the number of boys over the total amount of kids (8/20) which will equal 40%.
What is the center of the circle for this equation:
(x - 6)² + (y + 9)² = 25
Answer:
Step-by-step explanation:
Knowing this information, we can deduce that the center of the circle is at
(
6
,
−
2
)
, and the radius measures 3 units.
x
=
9
is a vertical line, while the circle will extend equal length in all direction, in function of it's radius. Looking at the centre and adding 3 to the x value, we get the point
(
9
,
−
2
)
. This point doesn't only lie on the circle; it also lies on the line
x
=
9
. Furthermore, this is the furthest possible distance from the center, so the line will only pass through this one point. Therefore, we can state that the line x = 9 is tangent to
(
x
−
6
)
2
+
(
y
+
2
)
2
=
9
If you graph the circle and the line you will get the same answer.

Write an equation for the line on the graph below:
Answer:
The equation would be x = -1
Step-by-step explanation:
Since the line is vertical, all y = all real numbers. This means that only x needs to be addressed, and since every x value is equal to -1, that's what the equation would be.
Answer:
x=-1
It's a vertical line so it touches all y's. The only x it touches is -1.

Does anyone know the answer to -8=16x + 9
Answer:
x = -17/16
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtraction Property of EqualityStep-by-step explanation:
Step 1: Define
-8 = 16x + 9
Step 2: Solve for x
[Subtraction Property of Equality] Subtract 9 on both sides: -17 = 16x[Division Property of Equality] Divide 16 on both sides: -17/16 = xRearrange/Rewrite: x = -17/16Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -8 = 16(-17/16) + 9Multiply: -8 = -17 + 9Add: -8 = -8Here we see that -8 does indeed equal -8.
∴ x = -17/16 is the solution to the equation.
