Answer: 300

Step-by-step explanation:

hight plus shadow hight! <3

The height of the building is 12 ft.

The correct relationship between the size of different parts of the same thing, or between one thing and another.

Given that, Mark is 6ft tall and casts a 15 ft shadow. At the same time of day, a nearby building casts a 30ft shadow.

The proportion here is, 6/15

Let the height of the building be x,

6/15 = x/30

x = 12

Hence, The height of the building is 12 ft.

Answer: How much do they cost-.....

Step-by-step explanation:

Answer:

14.91g/ ml

Step-by-step explanation:

Answer:

Step-by-step explanation:

Weight of honey= (703.55g - 345.8g)

= 357.75g

But

Density= mass/ volume

Mass of honey= 357.75g

Volume of honey=24ml

If we substitute the values, we have

Density=(357.75g/24ml)

=14.91g/ ml

Hence, the density honey in g/ml is =14.91g/ ml

I just know the greatest common factor is 2ab

Answer:

C

Step-by-step explanation:

slope is rise/run or y2-y1/x2-x1

We use the two points (0,1) and (2,0)

y2=0, y1=1, x2=2, x1=0

0-1=-1

2-0=2

-1/2=-1/2

This gives a slope of -1/2, Answer Choice C

Answer:

The Answer is C

Step-by-step explanation:

From Point (-2,2), we go to point (0,1). The x changed by two, and the y changed by one. Therefore, when x changes by one, y changes by one-half. This slope is negative, making the answer -1/2

Answer: 750 miles

Step-by-step explanation:

The gas mileage is 75 miles per 1/2 gallon of gasoline.

First find how many miles it can go on 1 gallon of gasoline:

= 75 ÷ 1/2

= 150 miles

If the scooter can go 150 miles on 1 gallon, the number of miles it will go on 5 gallons is:

= 5 * 150

= 750 miles

Answer: 3

Answer: 3

Step-by-step explanation: the equation is the question. XD

Answer:

The correct answer would be $126.00

Step-by-step explanation:

If you see how many times 40% goes into 100%, it would be 2.5 times. Then you multiply the 40% of the overall price ($50.40) times 2.5 and that gives you $126.

Given :

☄ Radius of circular pond = 6 m

☄ The path has a width = 1 m

To Find :

☄ Area of the path = ?

Formula we have to use here :

☄ Area of path = Length of path × width

☄ Length of path = Circumference of pond

Solution :

☄ Area of the path is 37.72 m²

Required Explaination :

☃ Length of path = Circumference of pond ☃

Now, subsitute the given values in above formula we get :

→ Length of path = Circumference of pond

→ Length of path = 2πr

→ Length of path = 2 × 22/7 × 6

→ Length of path = 264/7 m

Now,let's find the area of the path :

→ Area of path = Length of path × width

→ Area of path = 264/7 × 1

→ Area of path = 37.72 m²

Answer:

42.8°

Step-by-step explanation:

The sine rule states that for a triangle with lengths of a, b and c and the corresponding angles which are opposite the sides as A, B and C, then the following rule holds:

[tex]\frac{a}{sin(A)}=\frac{b}{sin(B)} =\frac{c}{sin(C)}[/tex]

Given that points A, B and C forms a triangle with angle A = 65°, distance from A-to-C = 90 m and the distance from B to C = 120 m.

The distance from A to C is the side opposite to angle B. Hence let b =  distance from A to C = 90 m.

The distance from B to C is the side opposite to angle A. Hence let a =  distance from B to C = 120 m.

Therefore using sine rule:

[tex]\frac{a}{sin(A)}=\frac{b}{sin(B)} \\\\\frac{120}{sin(65)}=\frac{90}{sin(B)} \\\\sin(B)=\frac{90*sin(65)}{120} \\\\sin(B) =0.6797\\\\B=sin^{-1}(0.6797)\\\\B=42.8^o[/tex]

Answer:

1. 70°

2. 42°

Step-by-step explanation:

they are both isosceles Triangles as both diagrams state that they have two sides the same length. therefore their base angles will be equal.

1. 55 + 55 = 110

180 - 110 = 70°

2. 180 - 96 = 84

84/2 = 42°

Answer:

Step-by-step explanation:

Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.
