Answer: 31

Step-by-step explanation:

The two disks that we know Gina has are: 2 and 8.

We want to find tha largest sum that Gina's disks can have:

This means that the other 3 disks must be the largest possible ones.

We know that Monique has the disks 7 and 9.

The already taken values are: 2, 7, 8, and 9.

The largest values remaining are:

10, 6 and 5.

Then the largest sum that Gyna's disks can have is given by the scenario where Gina draws these 3 disks, and the sum will be:

2 + 8 + 10 + 6 + 5 = 31

The two triangles are similar, What is the length of DE?
horsena [70]
<h2>Answer:</h2>

This is easy. All you need to do is set up a <u><em>proportional relationship</em></u>.

A proportional relationship uses variables to show similarities, in this case, in triangles.

\frac{2}{3} = \frac{x}{6.3}\\\\3x = 12.6\\\\x = 4.2

<u><em>x</em></u> represents the missing side.

As a town gets smaller, the population of its high school decreases by 8% each year. The senior class has 320 students now. In h
Semmy [17]

Answer:

in 13.95 years the senior class will have 100 students.

Step-by-step explanation:

P(h) = p(0.92)^t (equation for exponential change)

P(h) - population of highschool (or senior class) = 100

p - staring amount = 320

t = time in years

100 = 320(0.92)^t

1/3.2 = .92^t (divide both sides by 320)

log(1/3.2, .92) = t (log base 0.92 of 1/3.2 equals t)

13.9497 = t

MAVERICK [17]

Answer:

1:50 PM

Step-by-step explanation:

Left school at 10:38 AM,

took them 51 minutes,

38+51=89,

89-60=29,

so when they drove to the museum, it was 11:29 AM.

From here, they stayed at the museum for 1 hour and 26 minutes,

so they stayed at the museum until 12:55 AM since 29+26=55.

Now, it took them 55 minutes to drive back to the school,

so 12:55 plus another 55 minutes,

it's going to be 1:50 PM when Dale's class got back to school.
