Answer:

The water costs $1.90, the chips are $.95 and the milk is $3.80.

Step-by-step explanation:

Let m = milk

Let w = water

Let c = chips

2m+6w+7c =25.65      w = 2c     m = w + 1.90

For the first equation, substitute w for 2C and m for w + 1.90 to get:

2(w+1.90) +6(2c) + 7c = 25.65

2w+3.8+12c+7c=25.65

2w+19c = 21.85

Now substitute 2c for w:

2(2c)+19c =21.85

4c + 19c = 21.85

23c = 21.85

c = .95  Now that we know the cost of the chips we can use that to find the water and the milk for the original equations that we wrote at the top.

w = 2c

w=2(.95) = 1.90

m = w + 1.90 = 1.90+1.90 = 3.80

From ratio concept, the greater number number is 32 .

A ratio exists as an ordered pair of numbers a and b, written a / b where b does not equivalent to 0. A proportion exists in an equation in which two ratios stand set equal to each other. For example, if there exists 1 boy and 3 girls you could write the ratio as 1 : 3 (for every one boy there exist 3 girls)

Let the greater number be x .

The ratio given is 3:8 .

Thus, by the concept of ratio -

⇒ 3/8 = 12/x

⇒ x = (8/3 * 12)

∴  x = 32

Therefore, from ratio concept, the greater number number is 32 .

The distance between Ivy's house and the supermarket and the distance between the supermarket and the bank:
H&S = 1,014 M; and S&B = 854m. This is resolved using the Sine Theorem.

Notice that the Angles of a Triangle add up to 180° That is

∠A + ∠B  + ∠C = 180°

Thus,

∠C = 180° - 32° - 109°

= 39°

Recall the Sine Theorem which indicates;

a/SinA = b/SinB = c/SinC

thus given that

AC = 1,523m

We have

AC/SinB = BC/SinA

BC = AC/SinB * SinA

= 1523/Sin109° * Sin32°

BC =854m

Therefore

AC/SinB = AB/SinC
Thus,

AB = AC/SinB * SinC

= 1523/Sin109° * Sin39°
AB ≈ 1,014m

Answer:

x = 70

Step-by-step explanation:

x and 2x - 30 are supplementary angles , sum to 180° , then

x + 2x - 30 = 180 ( add 30 to both sides )

3x = 210 ( divide both sides by 3 )

x = 70

Answer:

2x - 30 and x degrees should add up to 180 degrees

2x - 30 + x = 180

3x = 210

x = 70 degrees

Based on the triangle midsegment theorem, the midsegments and the sides they are parallel to are:

MP is parallel to XY

PZ is parallel to WX

MZ is parallel to WY

The segment that connects the midpoints of two sides of a triangle is referred to as the midsegment of the triangle. All triangles possess three midsegments. According to the triangle midsegment theorem, the third side of the triangle that is directly opposite the midsegment is twice the size of the midsegment and it is parallel to it.

In the diagram showing triangle WXY with midpoints at points M, Z, and P, the midsegments are:

MP which is parallel to XY, also, MP = 1/2(XY)

PZ which is parallel to WX, also, PZ = 1/2(WX)

MZ which is parallel to WY. also, MZ = 1/2(WY)

The area of the kite exists 48 sq. ft.

The area of a kite exists half the outcome of the lengths of its diagonals. The formula to define the area of a kite exists:

Area = ½ × p × q.

Given that a kite contain diagonals of lengths 12 ft and 8 ft.

We know that the area of a kite having diagonals of length 'p' units and 'q' units exists

Area of kite = ½ (p × q)

Here, p = 12 ft and q = 8 ft.

Area of kite = ½ (p × q)

What is monthly payment formula?

The formula for monthly payment is:

[tex]M = \frac{P(\frac{r}{12})( 1+\frac{r}{12})}{( 1+\frac{r}{12})^n-1}[/tex]

We can find total interest as shown below:

Value of property = $475,000

Money available as a deposit = $80,000

P = 475,000-80,000

= 395000

t = 25 year

r = 2% = 0.02

n = 25*12 = 300

[tex]M = \frac{P(\frac{r}{12})( 1+\frac{r}{12})}{( 1+\frac{r}{12})^n-1}[/tex]

Putting the value of P, t, r, and n in the above formula

[tex]=\frac{395000(\frac{0.02}{12} )(1+\frac{0.02}{12}) }{(1+\frac{0.02}{12})^{300}-1}[/tex]

after solving the above expression

M = $1674.22

Interest = M*n-P

Putting the value of P, n and M

= 1674.22*300-395000

= 502266-395000

= 107,266

Rounding to nearest ten dollar

= $107,270
