Answer:

Can´t be determined.

Step-by-step explanation:

When you have a triangle with a 90 degree angle and a hypotenuse of 10, the other can´t be determined without another angle, or another side, the same for the little triangle with just the hypotenuse you can not calculate the size of the other sides or the other angles, and just by sight you can not make a correct statement about the similarity of the triangles.

Answer:

I'm not sure for my answer 'cuz I just learned this but i think its A because even though the size changes, the corresponding angle measure are the same and the corresponding sides are proportional.

(Tell me if I'm wrong.)

A is

$| - 9| + |9|$

absolute value is always positive, the minus sign vanishes (it literally means "how far away from zero" something is. distance can't be negative.)

B ist just 18

The area of a rectangular wall of a barn is 192 square feet. Its length is 8 feet longer than twice its width. Find the length a

xeze [42]

Answer:

Let l be length and w be the width

l = 2w+12

Area = (2w+12)*w = 224

2w^2 + 12w - 224 = 0

w^2 + 6w - 112 = 0

using quadratic formula

w=[ -6 +- {36- 4*1*(-112)}^0.5]/2*1

w = [-6 +- {484}^0.5]/2

w = [-6 +- {22}]/2

w = 16/2 or -28/2

w = either 8 or -14

Width can not be a negative number

wI’d think= 8 ft

length = 2*8+12 = 28 ft

There are three different hoses used to fill a pool: hose x, hose y, and hose z. Hose x can fill the pool in a days, hose y in b

WARRIOR [948]

Answer:

C) I and III only

Step-by-step explanation:

Let full pool is denoted by O

Days Hose x takes to fill pool O = a

Pool filled in one day x = O/a

Days Hose y takes to fill pool O = b

Pool filled in one day y = O/b

Days Hose z takes to fill pool O = c

Pool filled in one day z = O/c

It is given that

a>b>c

$a>b>c>d\\\implies x$

Days if if x+y+z fill the pool together = d

1 day if x+y+z fill the pool together $=O(\frac{1}{a}+\frac{1}{b}+\frac{1}{c})=\frac{O}{d}---(1)$

I) d < c

d are days when hose x, y, z are used together where as c are days when only z is used so number of days when three hoses are used together must be less than c when only z hose is used. So d < c

III) $\frac{c}{3}$

Using (1)

$\frac{bc+ac+ab}{abc}=\frac{1}{d}\\\\d=\frac{abc}{ab+bc+ca}\\\\As\quad(a>b>c)\\(ab+bc+ca)\frac{abc}{3ab}\\\\d>\frac{c}{3}$

Similarly

$\frac{bc+ac+ab}{abc}=\frac{1}{d}\\\\d=\frac{abc}{ab+bc+ca}\\\\As\quad a>b>c\\(ab+bc+ca)>3bc\\\\d=\frac{abc}{ab+bc+ca}$

So,

$\frac{c}{3}$

Kendall recently received a job offer which required him to move his house full of furniture across the country from Columbia, S

astra-53 [7]

Distance (in miles) Amount of fuel (in gallons)
1092 109
671 67
985 99

Relation, x/y = 1092/109 = 10.02
671/67 = 10.2
So, Relation is x = 10.02y

Hope this helps!
