I only have the answer for 1, but !

1. The area of a parallelogram is base times height. Since the area of that rectangle is twice the area of the circle, then the area of the circle is half the base times the height. It will be half of 2πr· r. The area of the circle will be πr2

Graph the line that passes through the given point and has the given slope m!

Veseljchak [2.6K]

Answer:

The line would be y = -1/4x + 27/4

Step-by-step explanation:

In order to find this, we first need to note that the original slope is -1/4. And since parallel lines have the same slope, we know our new line will have that same slope. Now, we can use that slope and the point in point-slope form and solve for y.

y - y1 = m(x - x1)

y - 6 = -1/4(x - 3)

y - 6 = -1/4x + 3/4

y = -1/4x + 27/4

Can someone help me with this problem? It’s Special Right Triangles: Decimal Answer. Round to the nearest tenth. Thank you ! 10

Triss [41]

Answer:

h = 1.4

c = 2.8

Step-by-step explanation:

For each problem, remember the special triangle side ratios then use a proportion. To solve, isolate the variable.

For the triangle with the variable h:

Since two of the angles are 45, this is an isosceles triangle. All isosceles triangles have two equal sides that are not the hypotenuse.

In a right isosceles triangle, the ratio for regular side to hypotenuse is 1 to √2.

$\frac{1}{\sqrt2} =\frac{h}{2} \\h = 2\frac{1}{\sqrt2} \\h = \frac{2}{\sqrt2} \\h = \frac{2\sqrt2}{2} \\h = \sqrt{2}$

h = √2

h ≈ 1.4

For the triangle with the variable c:

The is an equilateral triangle cut in half because the angles are 30 and 60.

The side ratio of altitude to hypotenuse is √3 to 2.

$\frac{\sqrt{3} }{2} =\frac{c}{4} \\\sqrt{3} = \frac{c}{2}\\2\sqrt3 = c$

c = 2√2

c ≈ 2.8

Solve the equation for x.

Ghella [55]

Answer:

- x/10 = 9

multiply by 10 on both sides

-x = 90

divided by -1 on both sides

x = -90

Tim throws darts at a dartboard that has numbers 1 through 20 and a bull's-eye in the middle. Tim throws a dart 24 times. He hit

schepotkina [342]

Answer:

1/6

Step-by-step explanation:

because you have 24 times he throw it and then 4 times he did hit the bull's eye so its 4/24 and then you divide both sides by 4 and 24/4 is 6 and 4/4 is 1 so 1/6 is the answer
