What’s the distance between (1, 7) and (-2, -4) please help

Answers

Answer 1

Answer:

Answer:

the slope is 11/3

so distance is 130 or 11.4 in decimal form

Answer 2

Answer:

Answer:

Exact distance = $√(130)$

Approximate distance = 11.40175

Explanation:

We'll use the distance formula

$d = √((x_1-x_2)^2+(y_1-y_2)^2)\n\nd = √((1-(-2))^2+(7-(-4))^2)\n\nd = √((1+2)^2+(7+4)^2)\n\nd = √((3)^2+(11)^2)\n\nd = √(9+121)\n\nd = √(130) \ \ \text{ ... exact distance}\n\nd \approx 11.40175 \ \ \text{ ... approximate distance}\n\n$

Let's start with sectioning off the little squares on the left that are jutting out of the top and bottom. Both of the squares are C*E, so multiply C*E twice to get the area of those little squares. That comes out to 12 feet.

Next is the main quadrilateral, the big one. You have to cut it off at the point the triangle starts to slope, so the end fo B.

But you also have to get the left part, so you have to add the length of C to the length of B to get the length of the quadrilateral. A encompasses the entire height, but not the part we want, because we already isolated those little squares. To get the height, just subtract the two E parts. The height is 6. The length is 8 feet. Multiply and get 48.

Add that to the previous 12 feet calculated to get 60.

Next, the triangle. The height is A, but only with one E. So subract the other E to get a height of 9. The length is D, but you have to subract B because that is part of the earlier quadrilateral. That makes it 9.

The formula for a triangle is height * length / 2. So, plug in the numbers-- 9 * 9 / 2

81/2

40.5.

Add to the previous 60 we got and that makes 100.5 square feet.

Hope this helped!

Using Distributive Property, what is the simplified answer to (6+9v)6 ?

Answers

36+54v

Multiply 6 with both 6 and 9v

(6+9v)6 = (6)(6) + (9v)(6) so now you just calculate them. 36 + 54z . I hope that's help

There are 88 girls and 96 boys in the sixth-grade what is the rate of girls to boysA- 88 girls for every 96 boys
B- i girl for every 1.09 boys
C- 44 girls for every 48 boys
D- 11 girls for every 12 boys

Answers

The correct option is D. 11 girls for every 12 boys.

We need to determine the ratio of the number of girls to the number of boys.

Given:

Number of girls = 88

Number of boys = 96

The ratio of girls to boys can be represented as "girls : boys."

To simplify the ratio, we can divide both the number of girls and the number of boys by their greatest common divisor (GCD). In this case, the GCD of 88 and 96 is 8.

Dividing both numbers by 8, we get:

Number of girls (after dividing) = 88 ÷ 8 = 11

Number of boys (after dividing) = 96 ÷ 8 = 12

So, the simplified ratio of girls to boys is 11 : 12.

Now, let's check which option matches the simplified ratio:

A. 88 girls for every 96 boys (Does not match)

B. 1 girl for every 1.09 boys (Does not match)

C. 44 girls for every 48 boys (Does not match)

D. 11 girls for every 12 boys (Matches)

The correct option is D. 11 girls for every 12 boys.
