Find the distance between two points<br> (2, -3) and (2,4).

Damm [24]

Answer:

The distance between the two points is 7 units

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

(2, -3) and (2,4)

substitute the values in the formula

$d=\sqrt{(4+3)^{2}+(2-2)^{2}}$

$d=\sqrt{(7)^{2}+(0)^{2}}$

$d=7\ units$

If the m∠1=123° m ∠ 1 = 123 ° and m∠2= (2x+7)° m ∠ 2 = ( 2 x + 7 ) ° , determine the value of x that supports l∥m l ∥ m . Show y

Georgia [21]

Answer:

Step-by-step explanation:

Let us assume that m<1 nad m<2 are supplementary. Since the sum of supplementary angles is 180degrees, hence;

<1 + <2= 180

123+2x+7 = 180

130+2x = 180

2x = 180 - 130

2x = 50

x = 50/2

x = 25

Hence the value of x is 25

Joan has 1/2 yard of felt. She will use 1/3 of it to make place cards. How much felt will she will use for place cards?

-Dominant- [34]

ANSWER

$\frac{1}{6} \: yards$

EXPLANATION

It was given that, Joan has

$\frac{1}{2} \: yard \: of \: felt$

and she will use

$\frac{1}{3}$
of it to make place cards.

We want to find how felt she will use for place cards.

We just have to find,

$= \frac{1}{3} \: of \: \frac{1}{2}$

$= \frac{1}{3} \times \frac{1}{2}$

$= \frac{1}{6}$

Therefore Joan will use

$\frac{1}{6}$

yards of felt for the place cards.
