Answer: Math is basically a form of measuring or expressing quantities, as defined by mankind. We can use our sensory organs for sensing, but we cannot have the idea of how much without the knowledge of numbers.

Write the following phrase as an inequality: 3 more than twice n is at most 50.

Margarita [4]

Step-by-step explanation:

3 more than twice n = 3+2n

3 more than twice n is atmost 50,

=> 3+2n <= 50 {(3+2n) is less than or equal to 50}

GIVING 100 POINTS!!! An observer (O) is located 900 feet from a building (B). The observer notices a helicopter (H) flying at a

slamgirl [31]

Answer:

1035.33 feet

Step-by-step explanation:

OBH is a triangle and the sum of the angles of a triangle = 180

∠OBH = 90°

∠OHB = 180 -(49 + 90) = 41°

The law of sines that the ratio of each side of a triangle to the sin of the angle opposite it is the same

Thus

A/sinα = B/sinβ = C/sinγ

where A, B and C are the three sides of the triangle and α, β, γ corresponding respectively to the angles opposite them.

Using the law of sines

$\frac{OB}{sin 41} = \frac{BH}{sin49}$

Therefore BH which is the height the helicopter is flying at is

$BH = OB \frac{sin49}{sin41}$

≈ 1035.33 feet

The area of the triangle ABD is 56cm2. Work out the length of CD

MrRa [10]

Answer:

8.2

Step-by-step explanation:

Area of triangle is calculated by multiplying height to the base and that divided by two

20 × h ÷ 2 = 56^2

h = 5.6

The square length of CD is equal to sum of square length of height and base

6^2 + 5.6^2 = CD^2

CD = 8.2

Use the scale factor to compare the perimeter and area of the original figure of the enlarged figure. Complete the statements ab

Reika [66]

Answer:

Part 1) The scale factor is 2

Part 2) The perimeter of the enlarged rectangle is 19 units

Part 3) The area of the enlarged rectangle is 19.5 square units (the area of the enlarged rectangle is 4 times the area of the original rectangle)

Step-by-step explanation:

we know that

A dilation is a non-rigid transformation that produce similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

The ratio of its perimeter is equal to the scale factor and the ratio of its areas is equal to the scale factor squared

step 1

Find the scale factor

Let

z ---> the scale factor

$z=\frac{3}{1.5}=2$

step 2

Find the perimeter of the enlarged rectangle

Multiply the perimeter of the original rectangle by the scale factor

The perimeter of the original rectangle is

$P=2(1.5+3.25)=9.5\ units$

The perimeter of the enlarged rectangle is

$9.5(2)=19\ units$

step 3

Find the area of the enlarged rectangle

Multiply the area of the original rectangle by the scale factor squared

The area of the original rectangle is

$A=(1.5)(3.25)=4.875\ units^2$

The area of the enlarged rectangle is

$4.875(2^2)=19.5\ units^2$

The area of the enlarged rectangle is 4 times the area of the original rectangle

step 4

Find the value of b

Multiply the corresponding side of the original rectangle by the scale factor

$b=3.25(2)=6.50\ units$

Verify the perimeter of the enlarged rectangle

$P=2(3+6.50)=19\ units$ ----> is ok

Verify the area of the enlarged rectangle

$A=3(6.50)=19.5\ units^2$ ---> is ok

A map of a park has a scalar of 1 inch to 1,000 feet. Another map of the same park has a scale of 1 inch to 500 feet. Which map

tester [92]

Answer:

The second map is larger in size

Step-by-step explanation:

Map 1 = scale of 1 inch to 100

Map 2= scale of 1 inch to 500

Lets assume, the parks have a length of 3000 ft and a width of 2000ft.

Map 1

Length = 3000/1000 = 3ft

Width = 2000/1000 = 2 ft

Map 2

Length: 3000/500 = 6 ft

Wdght: 2000/500 = 4ft

In both length and width, second map is larger in size.
