Question complète
Exercer:
En face, [MH] est une hauteur du triangle MAT.
a.Calculer MH, puis HT.
b. Eva dit: "".
A-t-elle raison? Expliquer.
MA = 7,8cm
MT = 7,5cm
AH = 3cm
Answer:
La réponse d'Eva est incorrecte
Step-by-step explanation:
Nous résolvons les questions abive en utilisant le théorème de Pythagore
c² = a² + b²
a) Application de la formule ci-dessus:
Étape 1
Trouver MH
MA² = MH² + HA²
7,8² = MH² + 3²
MH² = 60,84-9
MH² = 51,84
MH = √51,84
MH = 7,2 cm
Étape 2
Résoudre pour HT
MT² = MH² + HT²
7,5² = 7,2² + HT²
HT² = 56,25 à 51,84
HT = √4,41
HT = 2,1 cm
b) La formule pour le périmètre du triangle MAT =
MA + MT + AH + HT
= 7,8 + 7,5 + 2,1 + 3 = 20,4 cm
Le périmètre du triangle MAT est de 20,4 cm
Donc, la réponse d'Eva est incorrecte
If you change both to a fraction you would see that you have 1/6 and 1/4 (.25 as a fraction). So 1/5 would be in between them.
You could also change both as a decimal. 1/6 =.166666 and .25 so any number in between them would be correct such as .2 which is the same as 1/5.
Answer:
x > 9.
Step-by-step explanation:
Here it is just simplifying the inequality.
6 - 2/3x < x - 9
Add 2/3x to both sides.
6 < 5/3x - 9
Add 9 to both sides.
15 < 5/3x
Multiply by 3/5.
9 < x
Flip it.
x > 9.

Answer
12 (5 - 3)
Step-by-step explanation:
The greatest common factor is the largest number that will divide both numbers evenly. As an example, 6 is a common factor because it divides both 60 and 36. However, it is not the greatest common factor.
If I break 60 into it's prime factors, I would get 2 * 2 * 3 * 5.
If I break 36 into it's prime factors, I would get 2 * 2 * 3 * 3.
The two number have the factors, 2, 2, and 3 in common.
The greatest common factor is then: 2 * 2 * 3, or 12.
The expression can be factored as: 12 ( 5 - 3)
