Hannah has 8 over 9 of a pound of birdseed. She put 2 over 3 of a pound of birdseed into her bird feeders. How much birdseed doe

Mice21 [21]

8/9 - 2/3 = 8/9 - 6/9 = 2/9 of a pound left

She had 8/9 of a pound of birdseed to begin with. She used 2/3 of a pound of birdseed into her feeders. You have to get a common denominator, would be 9 and when you subtract what she used from what she had you get 2/9 of a pound of birdseed left.

Juan is enlarging a photo that has a length of 4 in and a width of 6 in. He would like to enlarge the picture by a scale factor

Svetlanka [38]

Answer: 60 in

Step-by-step explanation:

if the image is 3 times bigger, the length and width become...

4 in * 3 = 12 in. length

6 in * 3 = 18 in. width

so the perimeter is

12 * 2 + 18 * 2 = 60 inches!

Shelly and Jamie participate in a street relay race. Jamie must run from point B along AB⌢, which represents part of a roundabou

Gwar [14]

Answer:

Jamie must sprint 107 meter to pass Shelly at point A.

Step-by-step explanation:

Circumference of a sector of the circle is represented by,

Circumference = $\frac{\theta}{360}(2\pi r)$

where θ = central angle subtended at the center by an arc

r = radius of the circle

$m(\widehat{AB})$ = $\frac{123}{360}(2\pi )(50)$

= 34.1667π

= 107.34 meter

≈ 107 meter

Therefore, Jamie must sprint 107 meter to pass Shelly at point A.

What degree slope is a 16' ramp with a 35" rise

masha68 [24]

Answer:

10.5 Degree.

Step-by-step explanation:

The inclined length of the ramp is 16' i.e. 16 feet i.e. (16 × 12) = 192 inches.

And the rise of the ramp is 35" i.e. 35 inches.

We have to calculate the degree of slope from the above information.

If we consider the ramp as the hypotenuse of a right triangle, then the perpendicular height is 35 inches.

Then angle of slope is given by

$\sin \theta = \frac{Perpendicular}{Hypotenuse} = \frac{35}{192} = 0.182$

⇒ $\theta =\sin^{-1} (0.182)=10.5$ degree. (Answer)
