Answer:

The answer is actually 31.6 m (3 s.f.). The correct process will be use the sine rule to find out BC and CD. Then find out the length of AC by adding AB (which is 5.8 m) and BC (16.9 m after working out). Then work out the angle of CAD, which will be 46 degrees. Then use the cosine rule on triangle ACD to dine out AD.

Step-by-step explanation:

Step-by-step explanation:

the most common form of line equation is

y = ax + b

a is the slope of the line. it is expressed as the ratio

y coordinate change / x coordinate change

when going from one point to the other.

b is the y-intercept (the y value when x = 0).

once we have the slope, we get b by using the coordinates of one of the given points as x and y in the equation and since for b.

2 points are marked already :

(-3, 4) (3, -4)

x changes by +6 (from -3 to 3)

y changes by -8 (from 4 to -4)

the slope is -8/+6 = -8/6 = -4/3

the y-intercept is also clearly visible on the chart : the line crosses the y-axis precisely at (0, 0).

so, the y-intercept is 0.

Answer: y = (28/4)x + 4

Step-by-step explanation:

We'll be using 20, 144 (1) and 24, 172 (2) for this

slope = y2 - y1 / x2 - x1

slope = 172 - 144 / 24 - 20

slope = 28/4

y = mx + b

y = (28/4)x + b

We can then reduce 20, 144 by 4, 28

20, 144

16, 116

12, 88

8, 60

4, 32

0, 4

The y-intercept is when x = 0, so its 4.

Plug that into y = mx + b

y = (28/4)x + 4

12. 12.8 is the answer without rounding, 13 is the answer with rounding

story: you buy 4 apples for 3.2 cents each, since you cannot pay in less than a cent, you must give the seller 13 cents for the 4 apples

14. 12/7 is the answer without rounding, with rounding its 1

you have 3 1/7 of an apple, and your friend wants you to split it into 1 5/6 pieces, but you can't, so your friend is nice and only takes less than his part

Step-by-step explanation:

The essential thing to learn from this lesson is the translation of equations.  When f(x) = f'(x) + a, the graph of the equation is shifted up by a units.

When f(x) = f'(x + a), the graph of the equation is shifted left by a units.

Answer:

6

Step-by-step explanation:

24/6=4

6x4=24

6+6=12

6+6=12      12+12=24

Solution:

Given,

No. of marbles =24

No. of marbles each child received=4

No. of children in the group=?

Here,

No. of children in the group = No. of marbles/

No. of marbles

each child received

=24/4

=6

Hence, There were 6 children in the group.

Answer:

140

Step-by-step explanation:

35 ÷25%

35 ÷ 25/100

140

ok I am a little confused here but I think I may know what your asking.

What is 25% of 35? or you could be asking 35 is 25% of what number?

I'll answer both just in case.

What is 25% of 35?: 35 ÷ 4 = 8.75%

35 is 25% of what number?: 35 x 4 = 140

Answer:

D

Step-by-step explanation:

D is the only option where Tim has 23 or more dollars earned.

To show this I will solve each equation...

A) (-23)+9+9 = (-23)+18= -5

-5 < 0 so A doesn't work

B) (-23)+7+7+7 = (-23)+21= -2

-2 < 0 so B doesn't work

C) (-23)+12+9 = (-23)+21= -2

-2 < 0 so B doesn't work

D) (-23)+12+12 = (-23)+24= 1

1 > 0 so D does work!

* I am using 0 to compare each number with the result because Tim should have 0 or more dollars after paying his mom.

Hope this Helps!

Answer:

x = 2, 4

Step-by-step explanation:

Hi there!

x=√(2x-4)+2

Move 2 to the left:

x-2 = √(2x-4)

Square both sides:

x²-4x+4 = 2x-4

Combine like terms:

x²-6x+8 = 0

Factor:

(x-2)(x-4) = 0

Therefore, x = 2, 4.

The height of the kite above the ground is 36.8 ft

Let x be the height of the kite above Mamadou's hand.

Since the angle of elevation of the kite is 27° and the length of the kite's string is 75 ft long, the length of string, height of kite above Mamadou's hand and the horizontal distance between Mamadou and the kite form a right-angled triangle, with hypotenuse side, length of string of kite and opposite side, height of kite above Mamdou's hand, we have that

sin27° = x/75

Making x subject of the formula, we have

x = 75sin27

x = 75 × 0.4540

x = 34.05 ft

Since Mamadou's hand above the ground is y = 2.75 ft, the height of the kite above the ground, h = x + y

Substituting the values of the variables into the equation, we have

h = x + y

= 34.05 ft + 2.75 ft

= 36.8 ft

The height of the kite above the ground is 36.8 ft

We want to get the price per acre that she receives for the land, we will get that the price per acre is $2,777.8

First, we need to find the total area of the land.

There are two parcels, one with an area of 1 mi^2, and the other with dimensions of one-mile x half a mile, then the area of the other parcel is:

A' = (1 mi)*(0.5 mi) = 0.5 mi^2

The total area is the sum of these two, we get:

1 mi^2 + 0.5 mi^2 = 1.5 mi^2

And notice that we want to get the price per acre, knowing that:

1 mi^2 = 640 acres, then:

1.5 mi^2 = 1.5*(640 acres) = 900 acres.

The price per acre is equal to the quotient between the total price for the area and the number of acres, this gives:

P = ($2,500,000)/(900 acres)  = $2,777.8

So each acre costs $2,777.8
