Answer: 7x+2x = 108
find x, then you know the amounts.
Step-by-step explanation:
Answer:
84 oz. water and 24 oz. powder
Step-by-step explanation:
Okay so the ratio of water to powder is 7x:2x, x being however much you increase the number based off the question
The sum of water and powder is 108
so, 7x+2x=108
9x=108
x=12
that means water is 7*12=84 oz.
and powder is 2*12=24 oz.
to check: 84+24=108

Answer:
D. y = -1/2x + 18.5
Step-by-step explanation:
First you want to find the slope of the line that these coordinates make. To do this, use the slope formula: (y₂ - y₁) / (x₂ - x₁). I will use the first and last points.
(1, 18) & (6, 15.5)
Plug in these values:
(15.5 - 18) / (6 - 1)
Simplify the parentheses.
= (-2.5) / (5)
Simplify the fraction.
-2.5/5
= -1/2
This is your slope.
Now plug this into the standard slope-intercept equation: y = mx + b
y = -1/2x + b
b is the y-intercept, or the value of y when x = 0.
To find b, we want to plug in a value that we know is on this line: in this case, it is (1, 18). Plug in the x and y values into the x and y of the standard equation.
18 = -1/2(1) + b
To find b, multiply the slope and the input of x (1)
18 = -1/2 + b
Now, add 1/2 to both sides to isolate b.
18.5 = b
Plug this into your standard equation.
y = -1/2x + 18.5
This is your equation.

.Meiling needs 5 dollars 35 cents to buy a ticket to a show. In her wallet, she finds 2 dollar bills, 11 dimes, and 5 pennies. How much more money does Meiling need to buy the ticket?
Answer:
$2.20
Step-by-step explanation:
First you find how much money Meiling already has
2 dollars is $2.00
11 dimes is $1.10
5 pennies is $0.05
Add them all together
2 + 1.10 + 5 = 3.15
Then subtract how much Meiling need to how much Meiling has
5.35 - 3.15 = 2.20
Meiling still needs $2.20 for the ticket

Answer:
Step-by-step explanation:
The sum of the three interior angles of a triangle is always 180.
Knowing this, we can set up an equation for the given angles:
[tex]8x + 10x + 12x = 180[/tex]
[tex]30x = 180[/tex]
[tex]x = 6[/tex]
Knowing this, we can now plug it into the angles:
[tex]8x[/tex]
[tex]8 * 6[/tex]
[tex]48[/tex]
[tex]10x[/tex]
[tex]10 * 6[/tex]
[tex]60[/tex]

A 300 long wire is used to fence a rectangular plot whose length is twice its width find the length and breath
Answer:
Length = 100
Width = 50
Step-by-step explanation:
Given :
Length = 2 * width
If :
length = l
Width, w
l = 2w
Perimeter, P of rectangle :
P = 2(l + w)
P = 2(2w + w)
300 = 2(3w)
300 = 6w
w = 300/6
w = 50
l = 2w
l = 2(50)
l = 100

Use the converse of the side-splitter theorem to determine if T R is parallel to R S. Which statement is true? Line segment TU is parallel to line segment RS because StartFraction 32 Over 36 EndFraction = StartFraction 40 Over 45 EndFraction. Line segment TU is not parallel to line segment RS because StartFraction 32 Over 36 EndFraction not-equals StartFraction 40 Over 45 EndFraction. Line segment TU is parallel to line segment RS because StartFraction 32 Over 45 EndFraction = StartFraction 40 Over 36 EndFraction. Line segment TU is not parallel to line segment RS because StartFraction 32 Over 45 EndFraction not-equals StartFraction 40 Over 36 EndFraction.
Line segment TU is parallel to line segment RS because 32/36 = 40/45.
What is side splitter theorem?According to the "Side Splitter" Theorem, a line that crosses two sides of a triangle and runs parallel to its third side proportionally divides those two sides.
A line will divide two sides of a triangle proportionally if it runs parallel to one of the sides and intersects the other two.
Given
It is evident from the presented figure that QT=32, TR=36, QU=40, and US=45.
The opposite of the side splitter theorem asserts that a line is parallel to a third side if it divides two sides proportionally.
TU separates the two sides by a factor of in
QT/TR = 32/36 = 8/9
QU/US = 40/45 = 8/9
QT/TR = QU/US
It implies that the line TU divides the two sides equally.
Line segment TU is parallel to line segment RS using the reverse of the side splitter theorem because
32/36 = 40/45
Hence option 1 is correct.

Quadrilateral ABCD is a rectangle. BE=2x+1 and AC=6x−12 . What is BE ?
Answer:
BE=15
Step-by-step explanation:
Since E is the center, BE=2x+1
And AC is 6x-12 with E being a midpoint.
Since AC is 2 segments and BE is only 1 then you multiply 2x+1 by 2 so that
you can find x. You multiply 2x+12 by 2 because E is the midpoint so that means ED is the same value as BE
6x-12=4x+2
BD=AC
6x-4x-12=2
2x=2+12
2x=14
x=7
BE= 2x+1
2(7)=14+1=15
Bob wants to buy a television that costs $600, including taxes. To pay for the television, he will use a payment plan that requires her to make a down payment of $240, and then pay $68.50 each month for 6 months. What is the percent increase from the original cost of the television to the cost of the television using the payment plan?
Answer:
108.5% increase
Explanation:
Find how much payments will cost for 6 months
68.50 × 6 = 411
Add payments to down payment
411 + 240 = 651
Compare:
600 vs 651
Solve for percent increase:
651 ÷ 600 = 1.085
Convert decimal into percentage:
1.085 × 100% = 108.5%

the perimeter of a semicircle is 108 cm what is the perimeter of the square drawn on the diameter of the semicircle
Answer:
Step-by-step explanation:
the perimeter of the semi-circle would be the diameter plus the circumference of half of the circle.
They want to know the perimeter of a square using the diameter of the sem-circle as ONE side, so the perimeter of the square would be 4 times the ONE side.
We should recall:
diameter = 2 times the radius circumference of a cirlce = 2π r
How do we find the diameter of the of the semi circle?
The perimeter of the semi circle is given as 108 cm
Perimeter of the semicirle = 2r + π r diameter plus semi circumference
108 = r ( 2 + π) factor out the r and solve for r
108 / (2 + π) = r divide both sides by ( 2 + r)
Now we know r, the perimeter of the squqre is 4 times 2r or 8r
perimeter of square = 8 [ 108 / (2 + π) ] π I used 3.14
= 864 / 5.14
= 168.1 cm I got rounded to nearest tenth
