Answer:

Number of rats : Food weight = 1 : 5

Step-by-step explanation:

Number of rats in the group = 9

Weight of food carried away by them = 45 kg

Ratio of the number of rats and food weight = $\frac{\text{Number of rats}}{\text{Weight of food carried by the rats}}$

= $\frac{9}{45}$

= $\frac{1\times 9}{5\times 9}$

= $\frac{1}{5}$

Therefore, Number of rats : Food weight = 1 : 5

Lines e and f are parallel. The m9 = 80° and m5 = 55°. Which angle measures are correct? Check all that apply. m2 = 125° m3 = 55

Scorpion4ik [409]

I’ve answered this question before, so please see the attached image.

The solution would be like this for this specific problem:

1, 4, 5, 8 = 55
2, 3 , 6, 7 = 125
9, 12, 13, 16 = 80
10, 11, 14 ,15 = 100

So, the angle measures that are correct are:

m12 = 100

m8 = 55

m14 = 100

m16 = 80

ujalakhan01 can you answer these? 1. In Spencer’s garden, the number of rose bushes is 7 less than 1.5 times the number of carna

aniked [119]

Answer:

42.05x + 50.36

Step-by-step explanation:

1. It is 1.5c - 7 because tje mumber of rose bushes is 7 less that 1.5(c), not 1.5(7). So, it is (b).

2. 9.78(4.3x + 5.15)

42.05x + 50.36

Hope this helps:)

The angle of elevation to the top of a 15-story skyscraper is measured to be 4from a point on the ground 2,500 feet from the bui

alexandr1967 [171]

The point of observation is 2500 m away from the foot of the building.

The angle of elevation is 4°.

We need to find the height 'h' of the building.

With respect to 4°,

2500 is the adjacent side.

'h' is the opposite side.

The trigonometric ratio associating opposite & adjacent is tan.

We have

$tan\theta =\frac{opposite}{adjacent}$

$tan4^{o}=\frac{h}{2500}$

Cross multiplying we get

h = 2500 tan4°

h= 174.82 m

Option B) is the right answer.
