A 5.ft tall man casts a shadow along the ground that is 8 ft. long. At the same time a giraffe casts a shadow that is 12 ft. lon

forsale [732]

Answer : 7.5 ft

Step-by-step explanation:

when the length of the shadow is 8ft, the actual height of the man = 5ft

8:5

let the giraffe be 'x' ft tall.

if the length of the shadow is 12ft, actual height = x ft

12:x

8:5 x 12:x

$\frac{8}{5}$ × $\frac{12}{x}$

x= $\frac{15}{2}$

x=7.5 ft

Therefore, the giraffe is 7.5ft tall.

Week = w
1 hour = d

Formula

w = dm + c

The m is the gradient

The c is the d when w is 0

First let’s do m
m is basically how much the d changes from one point to another

So how much does d changes from 20 to 15.5

Find the linear equations giving brainlest

Nady [450]

Answer:

Step-by-step explanation:

Slope-intercept form of a linear equation: y = mx + b

m is the slope
b is the y-intercept - when x = 0

Problem 17: y = -4x + 2

slope: -4
y-intercept: (0, 2)

Problem 18: y = 1/7x - 5

slope: 1/7
y-intercept: (0, -5)

Problem 19:

y = 1x + 3

slope: 1
y-intercept: (0, 3)

Hope this helps!

△BCD is a right triangle. The length of the hypotenuse is 18 centimeters. The length of one of the legs is 14 centimeters. Wha

Romashka-Z-Leto [24]

Answer:

The answer to your question is b = 11.31 cm or 8 $\sqrt{2}$ cm

Step-by-step explanation:

Data

hypotenuse = 18 cm

one leg = 14 cm

second leg = ?

Process

1.- Use the Pythagorean Theorem to solve this problem

c² = a² + b²

c = hypotenuse

a = longer leg

b= shorter leg

2.- Substitution

18² = 14² + b²

-Solve for b

b² = 18² - 14²

-Simplify

b² = 324 - 196

b² = 128

-Find the prime factors of 128
