Answer:

A 36

Step-by-step explanation:

We can determine the scale factor

From triangle ABC BC =9

DEF EF = 90

We multiply by 10

The scale factor is 10

AC ( 10) = DF

We know DF = 360

b * 10 = 360

Divide each side by 10

10b/10 = 360/10

b = 36

I need the explanation and the answer of 14/40 in simplest form

Korvikt [17]

Answer:

$\frac{7}{20}$

Step-by-step explanation:

To simplify a fraction, you need to find the GCF (Greatest Common Factor) of the numerator (top number) and denominator (bottom number).

Factors of 14:

1, 2, 7, 14

Factors of 40:

1, 2, 4, 5, 8, 10, 20, 40

As you can see, 2 is the GCF of 14 and 40. So, we now divide both numbers by 2.

14 ÷ 2 = 7

40 ÷ 2 = 20

Therefore, $\frac{14}{40}$ in simplest form is $\frac{7}{20}$

The midpoint of is M(–1, –2). One endpoint is C(–9, –4). Find the coordinates of the other endpoint D.

lions [1.4K]

x coordinate of D = distance of 9 - 1 = 8 from point M

y coordinate of D = 4-2 = 2 from point M

so coordinates of D are (--1+8 , -2 + 2) = (7 , 0) answer

Use repeated subtraction to divide.1÷1/5

Mekhanik [1.2K]

1 - 1/5 = 5/5 - 1/5 = 4/5

4/5 - 1/5 = 3/5

3/5 - 1/5 = 2/5

2/5 - 1/5 = 1/5

1/5 - 1/5 = 0

We can subtract 1/5 from 1 a total of 5 times, so 1 ÷ 1/5 = 5.
