Elanso [62]3 years ago
4 0

Answer:

Step-by-step explanation:

The square root of 8 to the nearest 100th is 2.83

An empty 6-gal water jug weighs 0.5 lb. With 3 c of water inside, the jug weighs 2 lb. Which equation models the jug’s weight y
nikdorinn [45]
The slope would be 2/3 because that would leave pounds when multiplied by cups.

add 0.5 for the weight of the water jug

y = (2/3)x + 0.5

One sign lights up every 10 seconds. One sign lights up every 12 seconds. If they have just lit up at the same time, how many se
andrew11 [14]

Answer:

It will take 60 seconds for the signs to light up at the same time again.

Step-by-step explanation:

Given:

One sign lights up every 10 seconds

One sign lights up every 12 seconds

They have just lit up at the same time.

To find in how many seconds will it take for the signs to light up at the same time again.

Solution:

In order to find the time in seconds will it take for the signs to light up at the same time again, we need to find the least common multiple of the the times for which the given signs light up.

The numbers are 10 and 12.

To find the LCM, we will list the multiples of each and check the least common multiple.

The multiples of 10 and 12 are :

10\rightarrow 10,20,30,40,50,60,70

12\rightarrow 12,24,36,48,60

thus, we can see that 60 is the least common multiple.

Thus, the signs will light up at the same time time after every 60 seconds.

Answer:

approximately 25 weeks

Step-by-step explanation:

take $ 5000-$ 1325=$3675 this is what is remaining to achieve $5000

if you get $150 in one week what about $3675 is equal to how many weeks

$150=1 week

$3675=??weeks

<u>$</u><u>3675</u><u> </u><u>×</u><u> </u><u>1 week</u>

Parallelogram ABCD has vertex coordinates a(0,2) b (6,2) c (8,6 and d (2,6) write a rule to find the vertex coordinates of a par
Anastasy [175]

Answer:  The rule is explained.


Step-by-step explanation:  As shown in the attached figure, ABCD is a parallelogram with vertices A(0,2), B(6,2), C(8,6) and D(2,6).

Suppose, we are to find the vertices of a parallelogram PQRS that is smaller than but similar to ABCD, then we can follow the following rule.

Let us consider a positive real number k. Then the new coordinates of smaller and similar parallelogram PQRS will be

Co-ordinates of P will be (k,2+k),

Co-ordinates of Q will be (6-k,2+k),

Co-ordinates of R will be (8-k,6-k)

and

co-ordinates of S will be (2+k,6-k).

Taking any positive real value of k, we will get a new, smaller parallelogram which will be similar to ABCD.
