Answer:
( [tex]\frac{1}{2}[/tex], 0 )
Step-by-step explanation:
Given the 2 equations
4x + 3y = 2 → (1)
2x - 3y = 1 → (2)
Adding (1) and (2) term by term will eliminate the y- term, that is
6x = 3 ( divide both sides by 6 )
x = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]
Substitute x = [tex]\frac{1}{2}[/tex] into either of the 2 equations and evaluate for y
Substituting into (1)
4([tex]\frac{1}{2}[/tex] ) + 3y = 2
2 + 3y = 2 ( subtract 2 from both sides )
3y = 0 ⇒ y = 0
Solution is ( [tex]\frac{1}{2}[/tex], 0 )
The ratio of 3 L milk to 800 ml of water is,
Step-by-step explanation:
You start with milk : water = 7 :3
Total volume = 800 mL
Volume of milk = 7/10*800 = 560 mL
Volume of water = 3/10*800 = 240 mL water
Volume of milk must remain constant at 560 mL which is 2 parts
Therefore 3 parts water = 3/2*560 = 840 mL water final volume
You need to add 840 mL - 240 mL = 600 mL water .
Hope it helps

It takes Manisha 38 seconds to climb up the stairs of her house. If she spends 504 seconds doing this, how many minutes has she spent climbing the stairs of her house in a week?
Answer:
Manisha spent 8 minutes and 24 seconds in a week climibing the stairs of her house.
Step-by-step explanation: (totally my work, not copied)
Convert seconds to minutes.
60x8=480
60x9=540
so, 8 minutes
Find the remaining seconds.
504-480=24
Add remaining seconds to minutes
24sec+8min=8min24sec
So hence, your answer is 8 Minutes and 24 Seconds
Manisha spent 8 minutes and 24 seconds in a week climbing the stair of her house.

Step-by-step explanation:
Goal: For each spot you need to find the value associated with the column name.
Radius: half the maximum width of a circle
Height: The measure of how tall the cylinder is
Base Area: Can be found using the equation BA = π*r²
To find volume in terms of pi:
Only square the radius. Do not multiply the r² value by π. After squaring the radius, multiply it by the height of the cylinder.
Equation for Volume of a Cylinder = h*BA = h*π*r² =Volume
This can also be done in reverse if you know the volume and either the Base Area, the radius, or the height.
Simply do:
[tex]\sqrt{ \frac{V}{h*pi}} =r[/tex]
to find the radius
OR
[tex]\sqrt{ \frac{V}{BA}} =h[/tex]
to find the height
OR
[tex]\frac{V}{h} =BA[/tex]

Use the graphing calculator to graph these functions: y1= 2x ; y2= 2x2 ; y3 = 2x After what y-value does the exponential function appear to surpass the linear function?.
After the value of y is 4 does the exponential function definitely surpasses the linear function.
What is exponential function?
A function whose value is a constant raised to the power of the argument, especially the function where the constant is e.
Given
Use the graphing calculator to graph these functions: y1= 2x ; y2= 2x2 ; y3 = 2x.
As we can see y1=2x is a linear function and y3=2^x is a exponential function.
The graphs of y1 and y3 meet at 2 points i.e. at (1,2) and (2,4)
When you graph the equations their point of intersection is (2,4).
Therefore, when y > 4, the exponential function surpasses the linear function.

You are buying batteries, a stereo, and some CDs from the I.B. Electronics store. You can buy from this store online or in a physical store. You have a coupon for 10% off that can only be used in the physical store and a $5.00 off coupon that can only be used online. The sales tax of 5% only applies to the physical store. Shipping for the online store is a flat rate of $6.99. You are trying to decide whether to shop at the physical store or the online store. Using the pricing information below, how much money would you save by shopping in the physical store after all discounts, taxes, and shipping fees have been applied?
Item Quantity Physical Store Online Store
Batteries 2 packs $5.99/pack $4.99/pack

CDs 3 CDs $7.95/CD $8.95/CD
A. $19.62
B. It is more expensive to shop in the physical store.
C. $0.46
Answer:
Buy the batteries and stereo online:
4.99*2= $9.98 +$90 = $99.98
6.99-5.00 = $1.99
99.98+1.99=$101.97

7.97*3= $23.85
5% tax = 1.19
10% off = 2.39
$23.85 - $1.19= $22.66
22.66 + 101.97= $124.63
All in store:

Given that,
Kayson mixes 300 mL spinach, 200 mL of berries, and 42 mL of dressing to make a salad.
There are s mg of vitamin C per mL of spinach, b mg per mL of berries, and d mg per mL of dressing.
In 300 mL of spinach vitamin C is = (300 s)mg
In 200 mL of berries vitamin C is = (200 b)mg

ILL GIVE YOU 100 POINTS!! A polygon is graphed on a coordinate grid with (x, y) representing the location of a certain point on the polygon. The polygon is transformed using the rule (x, y)→(ax, ay) .
Which statement must be true?
If a equals 1, the image of the polygon is larger than the polygon.
If a is between 0 and 1, the image of the polygon is larger than the polygon.
If a equals 1, the image of the polygon is smaller than the polygon.
If a is between 0 and 1, the image of the polygon is smaller than the polygon.
Dilation involves changing the size of a polygon.
The true statement is: b. If a is between 0 and 1, the image of the polygon is smaller than the polygon.
The dilation rule is given as:
[tex]([/tex][tex]x,y)[/tex]⇒[tex](ax,ay)[/tex]
The size of the image, depends on the value of a.
