The length of one leg of a right triangle is 8 centimeters shorter than the

ra1l [238]

${34}^{2} + {b}^{2} = {42}^{2} \\ 1156 + {b}^{2} = 1764 \\ 1156 - 1156 + {b}^{2} = 1764 - 1156 \\ {b}^{2} = 608 \\ \sqrt{ {b}^{2} } = \sqrt{608} \\ b = 24.7$
I used the Pythagorean formula, which is a² + b² = c².
a² and b² are the two side legs while c² is the hypotenuse.
One of the side is 42 - 8 = 34 cm.

A bus travels 90 km in 1.5 hours (with a constant speed). How far can it travel in 7.2 hours (with the same speed)?

blondinia [14]

Answer:

distance=90km

time=1.5h

speed of the bus=distance /time

speed of the bus=90km/1.5h

speed of the bus=60km/h

therefore if 1.5h=60km/h

then 7.2h=(7.2x60)/1.5 =288km

maria [59]

If the problem is referring to the equivalent logarithmic equation log (20 *27).
We can easily find and solve its equivalent expression using one of the many identities available in logarithmic.
We can have the expression:

NEED Help!<br> 111=14g<br> and also 13.65=h + 4.88

crimeas [40]

Answer:

In this question if g and h is constant then;

111 = 14g

14g = 111

g = 111/14

g = 27.7 ~ 28

And also,

13.65 = h + 4.88

h + 4.88 = 13.65

h = 13.65 - 4.88

h = 8.77

Hope it helps!

Solve for x ....... thanks !

Len [333]

If we can match teh bases we can solve
because if x=x and xᵃ=xᵇ, we can conclude that a=b

16=2⁴
32=2⁵
rememeber that $(x^m)^n=x^{mn}$

$16^{3x+2}=32^{-2x-7}$
$(2^4)^{3x+2}=(2^5)^{-2x-7}$
$2^{4(3x+2)}=2^{5(-2x-7)}$
2=2 so we conclude that 4(3x+2)=5(-2x-7)

4(3x+2)=5(-2x-7)
expand/distribute
12x+8=-10x-35
add 10x both sides
22x+8=-35
minus 8 both sides
22x=-43
divide both sides by 22
x=-43/22
