Mathematics

Answer:

Step-by-step explanation:

Use the slope formula:

m = \frac{y2 -y1}{x2 - x1}

where m = slope

Given the coordinates

(-4, 4) ---> this means x1 = -4 , y1 = 4

(2, -5) ---> this means x2 = 2 , y2 = -5

Substitute these values into the slope formula:

m = \frac{y2 -y1}{x2 - x1}

m = \frac{-5 -4}{2 - (-4)}  = \frac{-9}{2+4} = \frac{-9}{6} = \frac{-3}{2}

0.24 times 0.4<br> Equals
Komok [63]

That would be 0.24(0.4). First, estimate the result: 0.24 is about 1/4, and (1/4)(0.4) is about 0.1.

0.24(0.4) = 0.096 (which agrees with the estimated answer, 0.1).

Lin has a scale model of a modern train. The model is created at a scale of 1 to 48. The height of the model train is 102 millil
alekssr [168]

Answer: The actual height of train = 4.896 meters.

Step-by-step explanation:

Since we have given that

Lina has a scale model of a modern train

Model is created at a scale is given by

1:48

Height of the model train = 102 millimeters

We need to find the actual height of the train.

Since there is direct variation between model and actual height of the train.

According to question,

\frac{1}{48}=\frac{102}{x}\\\\x=102\times 48\\\\x=4896\ millimeters\\\\x=4.896\ m

Hence, the actual height of train = 4.896 meters.

The 8th term of an arithmetic sequence is 12.5 and the 13th term is 20. What is the 25th term?
miv72 [106K]
From the 8th to the 13th there are five numbers, and the difference between the 8th and the 13th is 20-12.5=7.5, so the difference between two neighboring number is 7.5÷5=1.5
from the 13th and the 25th there are 12 numbers, so the total difference is 12*1.5=18
so the 25th term is 20+18=38
