The answer is going to be 29 because

I calculate the sum from starting with (-7+10))

So once I did that it’s 2-3(3-4(3)

Now you multiply the digits

2-3(3-12)

Now you subtract for 3-12

Which is -9 now you have 2-3(-9)

A negative times a negative is a positive

So 2+27=29

That’s how I got my answer. If this helps please give me brainiest and have a wonderful day

PLEASE HELP

Answer:

$593.26

Step-by-step explanation:

We know that the price of the laptop is $2500 and each year its resale value decreases by 25%. It means that 100 - 25 = 75% of the value is retained every year for the resale.

So, the resale value for 1st year = $\frac{75}{100} *2500 =$ $1875

for 2nd year = $\frac{75}{100} *1875 =$ $1406.25

for 3rd year = $\frac{75}{100} *1406.25 =$ $1054.7

for 4th year = $\frac{75}{100} *1054.7 =$ $791.01

for 5th year = $\frac{75}{100} *791.01 =$ $593.25

Or we can use the following formula to find its resale value after 5 years:

$2500*(0.75)^5 =$ $593.26

A model ship is built to a scale of 1 cm : 5m. The length of the model is 25 cm. What is the length of the actual ship?

Anestetic [448]

Answer:

The length of the actual ship is 125 meters.

Step-by-step explanation:

Scaling

Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing by a constant factor. We use scaling for example, when representing geographic locations on a map.

A model ship is built to a scale of 1 cm: 5 m. This means that each centimeter of the model represents an actual length of 5 m.

The length of the model is 25 cm, thus the real ship has a length of 25*5 = 125 m.

The length of the actual ship is 125 meters.
