The area of the mojave desert is 25,000 square miles. A scale drawing of the mojave desert has an area of 10 square inches. What is the scale of the map? i need a middle explanation because if not then my teacher will think i cheated and give me an f and my parents will not allow me to fail so could i please get a 7th grade explanation?

Answers

Answer 1

Answer:

The scale of the map will be: 50 miles = 1 inch or 50 : 1

Explanation

Actual area of the Mojave desert is 25,000 square miles and the scale drawing has an area of 10 square inches.

Suppose, the scale of the map is: $x$ miles = 1 inch

So, 1 square inches = $x^2$ square miles

and 10 square inches = $10x^2$ square miles

So, the equation will be .....

$10x^2=25000\n \n x^2= 2500\n \n x=√(2500)=50$

Thus, the scale of the map will be: 50 miles = 1 inch or 50 : 1

Answer:

A= 48°

B=60°

C=72°

D=20°

E=20°

F= 160°

G=160°

Step-by-step explanation:

Take a look at the picture above. (please excuse me for the sloppyish writing lol)

Answer:

$A =48 (supplementray), \n B = 60(supplementray), \n C =72(angle \:on\: a \:straight \:line) , \n D =20 (supplementray), \n E =20 (vertically \: opp \: angles), \n F = 160(angle \:on\: a \:straight \:line), \n G =160(vertically \:opp \: angles) .$

A medical office is replacing their existing flooring with carpeting in the waiting and office areas and laminate flooring in the patient exam rooms. If each of the 10 exam rooms is 10 feet by 10 feet, the waiting area is 20 feet by 15 feet, and the office area is 25 by 20 feet, how many total square feet of flooring will they be replacing?

Answers

So first, you would multiply 10 times 10 to get 100 square feet. And since there are 10 exam rooms, you multiply 100 to 10 and you would get 1000. Then to calculate the waiting area, you multiply 20 times 15 to get 300 square feet. Then the office area would be 25 times 20 which is 500. So you would add up 1000+300+500. The answer comes out as 1800 square feet. Hope this helped! Good luck!

On a coordinate plane, a parabola opens up in quadrant 1. It goes through (2, 12), has a vertex at (5, 3), and goes through (8, 12). Write the equation of the function whose graph is shown. y = (x + )2 +.

Answers

Answer:

Step-by-step explanation:

You have a vertex coordinate and 2 points. In order to write the equation for that parabola, you only need the vertex and one point. We will fill in the following work form of the parabola:

$y=a(x-h)^2+k$ , where h and k are from the vertex and x and y are from the point. Filling in:

$12=a(8-5)^2+3$ and

$12=a(3)^2+3$ and

$12=9a+3$ and

9 = 9a s0

a = 1.

Now we can write the equation, filling in a, the only unknown we had, which we now know is 1:

$y=1(x-5)^2+3$

Answer:

y = 1(x + -5)2 + 3
