What is the distance between (4, 7)(4,7)left parenthesis, 4, comma, 7, right parenthesis and (2, 2)(2,2)left parenthesis, 2, com
tester [92]

Answer: square root of 29

Step-by-step explanation:

Given the question :

Distance between (4, 7) and (2, 2)

Distance between two points is given by:

Distance = sqrt[(X2 - X1)² + (Y2 - Y1)²]

X1 = 4 ; Y1 = 7 ; X2 = 2 ; Y2 = 2

Distance = sqrt[(2 - 4)² + (2 - 7)²]

Distance = sqrt[(-2² + - 5²)]

= sqrt(4 + 25)

= sqrt(29)

Two similar FOR SALE signs have a scale factor of 5:3. The largest sign’s perimeter is 60 inches. Find the small sign’s perimete
Ulleksa [173]

The small sign's perimeter is 36 inches

Step-by-step explanation:

The scale factor between two figures is obtained by:

Scale = \frac{P_{l}}{P_{s}}

So,

We know that

Scale= 5:3\\P_l = 60\ in\\

Putting the values in the above equation of scale factor we get

\frac{5}{3} = \frac{60}{P_s}

Cross multiplication

5 * P_s = 60*3\\5P_s = 180

Dividing both sides by 5

\frac{5P_s}{5} = \frac{180}{5}\\P_s = 36

Hence,

The small sign's perimeter is 36 inches

Oliba is 48 inches tall and 2/3 as tall as her brother how tall is her brother
Goryan [66]
X= brother's height

Multiply 2/3 by the brother's height (x). This equals the sister's 48 inch height.

2/3x= 48
divide both sides by 2/3
x= 48 ÷ 2/3
multiply by the reciprocal of 2/3
x= 48 * 3/2
x= (48*3)/2
x= 144/2
x= 72 inches, the brother's height

ANSWER: The brother is 72 inches tall.

Hope this helps! :)

{7, 8, 9, 10} {9, 10, 11, 12} Which of the following shows the intersection of the sets? A. {9, 10} B. {7, 8, 9, 10} C. {9, 10,
lara31 [8.8K]

Answer:

<h3> { 9 , 10 }</h3>

Option A is the correct option.

Step-by-step explanation:

Let the sets be A and B

A = { 7 , 8 , 9 , 10 }

B = { 9 , 10 , 11 , 12 }

<u>The intersection of sets A and B is </u><u>the</u><u> </u><u>set</u><u> </u><u>of</u><u> </u><u>all</u><u> </u><u>ements</u><u> </u><u>which</u><u> </u><u>belongs</u><u> </u><u>to</u><u> </u><u>both</u><u> </u><u>A</u><u> </u><u>and</u><u> </u><u>B</u><u>.</u>

The intersection of sets A and N is denoted by ( A ∩ B ) and read as A intersection B.

A ∩ B = { 7 , 8 , 9 , 10 } { 9 , 10 , 11 , 11 , 12 }

Now, list the elements which are present in both sets. A ∩ B = { 9 , 10 }

Hope I helped!

Best regards!
