Matt has a rectangular garden that is 10 ft wide and 24 Ft long . He wants to build a fence from one corner to the opposite corn

iogann1982 [59]

He needs 26 feet of fence.

The diagonal of the rectangle forms the hypotenuse of a right triangle. The two legs would be the width of the rectangle, 10, and the length, 24:

10²+24² = c²
100+576 = c²
676 = c²
c = √676 = 26

Based on the cumulative frequency histogram, determine the number of swimmers who swam between 200 and 249 yards. Determine the

Lostsunrise [7]

Answer:

$(a)\ 200 \to 249 =3$

$(b)\ 150 \to 199 = 0$

$(c)\ Total = 20$

Step-by-step explanation:

Given

See attachment for cumulative frequency histogram

Solving (a): Swimmers between 200yd and 249yd

To do this, we simply read the data from the 0 mark

From the histogram, we have:

$0 \to 249 = 15$

and

$0 \to 199 = 12$

So:

$200 \to 249 = 0 \to 249 - 0 \to 199$

This gives:

$200 \to 249 = 15-12$

$200 \to 249 =3$

Solving (b): Swimmers between 150yd and 199yd

To do this, we simply read the data from the 0 mark

From the histogram, we have:

$0 \to 149 = 12$

and

$0 \to 199 = 12$

So:

$150 \to 199 = 0 \to 199 - 0 \to 149$

This gives:

$150 \to 199 = 12-12$

$150 \to 199 = 0$

Solving (c): Total swimmers

To do this, we simply read the longest bar of the histogram

$Longest = 20$

Hence:

$Total = 20$

Give the equation of the circle centered at the origin and passing through the point (0,-8)

Norma-Jean [14]

Answer:

The answer to your question is x ² + y² = 64

Step-by-step explanation:

Process

1.- Find the length of the radius

C (0, 0)

P (0, -8)

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

d = $\sqrt{(0- 0)^{2}+ (-8 - 0)^{2} }$

d = $\sqrt{64}$

d = 8

2.- Find the equation of the circle

$(x - h)^{2} + (y - k)^{2} = r^{2} \\$

h = 0 and k = 0

$(x - 0)^{2} + (y - 0)^{2} = 8^{2}$

x² + y² = 64

X 50 50 X = degrees Please help with this problem I am going crazy

sveta [45]

Answer:

x=80°

Step-by-step explanation:

Triangles always add up to 180°.

As you have 2 angles, you would have to add them together and then take it away from 180° to get your answer.

50+50=100°

180-100=80°

Hope this helps :)
