thunder from a bolt of lightning travels 1/10 mile in 1/2 second at this rate how many miles can a travel in one second
frutty [35]

Answer:

It travels 1/5 mile in one second

Step-by-step explanation:

1/10 * 2 = 2/10 = 1/5

Since the bolt of lightning travels 1/10 mile in half a second, then to find how much it travels in one a second you simply multiply 1/10 by 2, which equals 2/10, which can be simplified to 1/5.

A directed line segment on a gridded map shows the path of a hot air balloon from 1(0,0) to B(8,4). Each grid unit represents 1
aivan3 [116]

Answer:

Step-by-step explanation:

There is  a point V with ration 6 to 2, therefore we must find the coordinates of point V and the distance from A to V

<u>According to the graph</u>

c^{2}=x^{2}+y^{2}\\c^{2}=8^{2}+4^{2}\\c=\sqrt{64+16}=8.9.4\\sin\alpha =\frac{4}{8.94}

α≅27°

V=2*8.94/6 (ratio 6:2)

V=2.98mile

sin27=\frac{y}{2.98}\\y=sin27*2.98=1.35\\cos27=\frac{x}{2.98}\\x=cos27*2.98=2.65

coordinates of V = (2,65;1.35)

Distance from A to V

d_{AV}=2.98 miles

finally

Mary's mistake is to take the 6 to 2 ratio as the distance traveled from the globe only in the x direction

On a coordinate plane, a line is drawn from point a to point b. point a is at (7, negative 2) and point b is at (negative 8, neg
dimaraw [331]

The coordinate of the partition c on the line segment is (1.2, -4.7)

<h3>How to determine the coordinates of the partition?</h3>

The coordinates are given as:

A = (7,-2)

B = (-8,-9)

m:n = 5:8

The coordinate of the partition is calculated using:

(x,y) = \frac{1}{m + n} * (mx_2 + nx_1, my_2 + ny_1)

So, we have:

(x,y) = \frac{1}{5 + 8} * (5 * -8 + 8 * 7, 5 * -9 + 8 * -2)

Evaluate the sum and products

(x,y) = \frac{1}{13} * (16, -61)

Evaluate the product

(x,y) = (1.2, -4.7)

Hence, the coordinate of the partition on the line segment is (1.2, -4.7)
