Complete question :
En France, en 1900, la taille moyenne des femmes était de 1,54 m et celle des hommes de 1,66 m. Entre
1900 et 2010 ces tailles moyennes ont augmentées d'environ 5,55%.
Calculer, en mètres, l'arrondi au centième des tailles moyennes des femmes et des hommes en 2010.
Répondre :
Femmes = 1,63
Hommes = 1,75 m
Explication étape par étape:
Étant donné que :
Taille moyenne en 1900:
Hommes = 1,66 m
Femmes = 1,54 m
Pourcentage d'augmentation de poids d'ici 2010 = 5,55%
1 + 5,55% = 1 + 0,0555 = 1,0555
D'où,
Taille des femmes en 2010:
1,0555 * 1,54 = 1,62547 = 1,63 m
Pour la taille des hommes en 2010:
1,0555 * 1,66 m = 1,75213 = 1,75 m

Just took test
Estimate 12.32+7.636 by first rounding each number to the nearest tenth.
pls help need the right answer thank u
===========================================================
Explanation:
12.32 rounds to 12.3 when rounding to the nearest tenth (aka one decimal place). The digit in the tenths place stays the same because the next digit over is not 5 or larger.
7.636 rounds to 7.6 when following the same rule
Adding those two rounded values gets us 12.3+7.6 = 19.9
If the value of x for normal distribution is 35, the mean of normal distribution is 65 and the standard deviation is 25, then calculate the standardized random variable, and P(X < 35).
Answer:
[tex]Z=-1.2[/tex]
Step-by-step explanation:
From the question we are told that:
Normal distribution [tex]x=35[/tex]
Mean of normal distribution [tex]\=x=65[/tex]
Standard normal distribution deviation [tex]\sigma= 25[/tex]
Generally the equation for standardized value is mathematically given by
[tex]Z=\frac{x-\=x}{\sigma}[/tex]
[tex]Z=\frac{35-65}{25}[/tex]
[tex]Z=\frac{35-65}{25}[/tex]
[tex]Z=-1.2[/tex]
Therefore the standardized value of x is
[tex]Z=-1.2[/tex]

CH
LM
CJ
Answer:
Step-by-step explanation:
LG: is a chord. Are there others?
CH: is a radius. C is the center of the circle.
LM: You have to draw in LM. LM would be a secant. It cuts the circle in exactly two places.
CJ: Anything coming from C and ending at the circumference is going to be a radius.

Answer:
12cm squared
Step-by-step explanation:
The area of a triangle is 1/2bh
A = 1/2 x 4 x 6
A = 4 x 3
A = 12 cm squared
Answer:
The answer is B: 12 cm^2.
Step-by-step explanation:
The formula for the area of a triangle is b * h / 2 (base times height divided by two).
6 * 4 = 24
24 / 2 = 12
And since we're looking for area, the answer would be squared, as all areas are.
The answer: 12 cm^2.
Brainliest would be really really greatly appreciated!!!!

write 43600000×56000 in scientific notation
Answer:
(4.36x10^7)x(5.6x10^4)
Step-by-step explanation:
To answer the question what is 43600000 in scientific notation let’s recall how to convert 43600000 to scientific notation as detailed on our home page.
When you split the number 43600000 into a coefficient and a power of 10 you do get 43600000 in exponential form, but there is an indefinite number of possibilities.
As you probably want 43600000 in normalized scientific notation, the coefficient or significand of 43600000 in scientific notation must be in the interval [1,10[.
As there are many ways to express 43600000 in scientific notation, in this post we mean 43600000 in normalized scientific notation, unless stated otherwise. Therefore:
43600000 in scientific notation = 4.36 × 107.
Now you can do that for the other one to found out what it is equal to.

Tim filled his beach ball with 800 cubic inches of air. It loses 30% of its remaining air every 15 days. Which expression models how much air will be left after 5 months? (Let 15 days = twice a month.)
Answer:
22.6in³
Step-by-step explanation:
a = 800(0.7)^(150/15)
a = 800(0.7)^(10)
a = 22.6in³

Mike measured the stage where his band was going to play to determine if it is a right triangle. Does the stage with side lengths of 36 feet, 48 feet, and 60 feet form a right triangle
Answer:
let
hypotenuse[h]=60ft
base[b]=36ft
perpendicular [p]=48ft
by using Pythagoras law
p²+b²=h²
48²+36²=60²
2896≠3600
since p²+b²≠ h²[so the stage is not in a right angled triangle]but it is scalene triangle
What is the value of x in the equation 3x − 2 = x + 8?
Answer:
x=5
Step-by-step explanation:
We need to find the value of x the given equation: 3x-2=x+8
the goal when solving for equations is to isolate the variable onto one side, and have the number (value of what x is) on the other side
here's the equation:
3x-2=x+8
first, add 2 to both sides
3x-2=x+8
+2 +2
___________
3x=x+10 (2 goes away on the left side, as -2+2=0)
now, subtract x from both sides
3x=x+10
-x -x
______
2x=10 (x goes away on the right side, as x-x=0)
we have the variable isolated on one side, with the number on the other, but we need the value of x by itself (1x)
divide both sides by 2
x=5 (because 2x/2=1x, or x. 10/2=5).
therefore, the value of x is 5
Hope this helps!
