photoshop1234 [79]3 years ago
5 0

Answer:

The equation would be y = x + 5, in which x is the number of weeks and y is the number of books he has.

Step-by-step explanation:

We know this because even at 0 weeks, he still has 5 books. Therefore we put this as the constant at the end. Then we can add the number of weeks since the rate is one book per week.

A submarine is searching for underwater features. It is accompanied by a small aircraft
Ivanshal [37]

Answer:

255 m

Step-by-step explanation:

From the given question, the surface of the water body is the reference point. And this point is assumed to be 0, so that any distance above it is positive, and any distance below is negative. This is synonymous to the number line system.

Thus,

For the aircraft, its height = +200 m

For the submarine, its depth = -55 m

So that the difference between the submarine and aircraft can be determined as;

200 - (-55)

= 200 + 55

= 255 m

The distance between the submarine and aircraft is 255 m.

Dori and Malory are tracking their steps taken as a health goal. Dori leaves her house at 12:00 p.m. and walks at 50 steps per m
docker41 [41]

Hi There!


Dori leaves her house at 12pm.

50 steps per minute until 12:20pm.

Dori has a 20 minute advantage over Malory, find the amount of steps she is ahead by,

12 - 12:20pm. steps = 20 minutes = 20 x 50 = 1000 steps


Malory leaves her house at 12:20pm.

Walks 90 steps per minute.

12:20 -  12:30 pm. = 10 minutes = 10 x 90 = 900


Dori 12:20 - 12:30pm. = 10 minutes = 10 x 50 = 500

500 + 1000 = 1500


Mallory 12:30 - 12:40 = 10 minutes = 10 x 90 = 900

900 + 900 = 1800


Dori 12:30 - 12:45pm. = 15 minutes = 15 x 50 = 500

1750 + 500 = 2250


Mallory 12:40 - 12:45pm. = 5 minutes = 10 x 90 = 900

450 + 1800 = 2250


Answer: they have the same number steps at 12:45 p.m.


Hope This Helps :)

Need help ASAP to this math question about how many gallons it will take to fill a pool
NARA [144]
1 cubic foot = 7.48 gallons

hence
\frac{7.48 gal}{1 ft^3} =1

unit conversion
\frac{3000 ft^3}{} \times \frac{7.48 gal}{1 ft^3} =  3000 \times 7.48 gal

3000 x 7.48 =22440
