Answer:

A dilation factor by 1/2

Step-by-step explanation:

Find the distance of AB and BC which is 4 for each of them. A'B' and B'C' distance is 2. 4 * 1/2 = 2. Therefore the answer must be 1/2.

Step-by-step explanation:

First, a half plane can be defined as one side of a line, e.g. x < y-3.

1: True. A solution to two half planes is where the two half planes intersect. If they never intersect, then there literally cannot be a solution.

2: False. Take, for example, y=x and y=x+1. These two lines are parallel because in the equation y=mx+b, m represents the slope, and in these two lines, x is multiplied by 1, so both lines have the same slope and are therefore parallel. Then, take two boundary planes -- y > x and y>x+1. If we graph this out (see picture), the planes clearly intersect when y>x+1. The solution is where the planes intersect, so there is a solution area

Answer:

8 pipes

Step-by-step explanation:

given that when height increases also time increases and automatically no of pipes will be decreased Mathematically;

h∝t•1/p

remove proportionality symbol and we will get

h=kt

p

make k as subject and we'll get

k=hp

t

find the value ok k

k=3×5

4

k=15

k=3.75

from h=kt. make p as subject and the answer should be

p=kt. find p

h

p=3.75×10

Answer:269276796088

Step-by-step explanation:

Answer:

Step-by-step explanation:

[tex]\frac{3x-y}{4x+5y}=\frac{3}{5}\\\\[/tex]

Cross multiply

5*(3x-y) = 3*(4x + 5y)

5*3x -5*y = 3*4x + 3*5y

15x - 5y = 12x + 15y

15x - 12x = 15y + 5y

     3x    =  20y

     3x = 4y * 5

[tex]\frac{3x}{4y} = 5[/tex]

Answer:

Improper Fraction-n=96/5     Mixed Number-n=19 1/5

Step-by-step explanation:

Answer:

n = [tex]\frac{96}{5}[/tex]

Step-by-step explanation:

Given

[tex]\frac{12}{5}[/tex] = [tex]\frac{n}{8}[/tex] ( cross- multiply )

5n = 96 ( divide both sides by 5 )

n = [tex]\frac{96}{5}[/tex]

Answer:

x =4

Step-by-step explanation:

First we need to find the length of RT

Since the triangle on the left (RST) is a right triangle, we can use trig functions

sin theta = opp / hyp

sin 60 = 2 sqrt(3) / RT

RT sin 60 = 2 sqrt(3)

RT = 2 sqrt(3) / sin 60

RT = 2 sqrt(3) / (sqrt(3)/2)

RT = 4

Now we can find x

Since the triangle on the right (QRT) is a right triangle, we can use trig functions

tan theta = opp /adj

tan 45 =  x/ RT

tan 45 = x / 4

4 tan 45 = x

4 (1) = x

4 =x

Answer:

[tex]5x^3\sqrt{6}[/tex]

Step-by-step explanation:

We need to simplify

[tex]\sqrt{3x^4}\times\sqrt{5x^2}\times\sqrt{10}[/tex]

Right away we can take out the perfect squares. Remember a perfect square is the result of multiplying any value by itself.

[tex]= x^2\sqrt{3}\times x\sqrt{5}\times\sqrt{10} \\= x^3\sqrt{3\times 5 \times 10}\\= x^3\sqrt{3 \times 5 \times 5 \times 2 }\\= 5x^3\sqrt{6}[/tex]

The square root of 3x⁴ times square root of 5x² times square root of 10, the product of all the term is,  5x³ [tex]\sqrt{6}[/tex]

In mathematics, square roots is a concept in which, if we multiply square roots of any number by itself then it will give us an original number.

if 'a' is square root of 'b' then it will represent as, a = √b.

Given that,

three terms,

[tex]\sqrt3{x^{4} }[/tex]

[tex]\sqrt{5x^{2} }[/tex]

[tex]\sqrt{10}[/tex]

by multiplying all the three terms,

⇒ [tex]\sqrt3{x^{4} }[/tex] × [tex]\sqrt{5x^{2} }[/tex] × [tex]\sqrt10} }[/tex]

⇒  √(3x⁴×5x²10)

⇒   √ 150x⁶

⇒     5x³ [tex]\sqrt{6}[/tex]

Hence, the product is   5x³ [tex]\sqrt{6}[/tex]

Answer:

d=13.8

Step-by-step explanation:

secant-secant theorem: (a+b)b=(c+d)d

(14+20)14=(16+d)16

34*14=256+16d

220=16d

d=13.75

Answer:

[tex]\frac{14}{16}=\frac{20}{d}[/tex]

[tex]14d=16\cdot \:20[/tex]

Multiply 16 × 20

[tex]14=320[/tex]

Answer:

A. 21, 27, 33, 39

Step-by-step explanation:

an =15 + 6n

Let n=1  

a1 = 15 +6(1) = 15+6 = 21

Let n=2  

a2 = 15 +6(2) = 15+12 = 27

Let n=3  

a3 = 15 +6(3) = 15+18 = 33

Let n=4  

a4 = 15 +6(4) = 15+24 = 39

Answer:

A

Step-by-step explanation:

You do not know where n starts. Is it 1 or zero or something else. Raise your hand and complain.

I'll assume that n = 1 to start with

n = 1

15 + 6(1) = 21

n = 2

15 + 6(2) = 15 + 12 = 27

n = 3

15 + 6* 3 = 33

n = 4

15 + 6*4 = 39

Answer:

40°, 80°, 120°, 120°

Step-by-step explanation:

sum the parts of the ratio, 1 + 2 + 3 + 3 = 9 parts

The sum of the interior angles of a quadrilateral is 360°

Divide this by 9 to find the value of one part of the ratio.

360° ÷ 9 = 40° ← value of 1 part of the ratio

Then

2 parts = 2 × 40° = 80°

3 parts = 3 × 40° = 120°

The 4 angles are 40°, 80°, 120°, 120°
