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

The cities Cleveland, Ohio; Erie, Pennsylvania; and Rochester, New York, in respective order, lie approximately in a straight li

Ann [662]

Answer:

Erie to Rochester is 145 miles

Step-by-step explanation:

If we designate the points of interest as C, E, and R, we are told that ...

CE + ER = CR . . . . . the various distances are segments of a straight line

For CE = 94 and CR = 239, we can fill in the given information and solve for ER.

94 + ER = 239

ER = 239 -94 . . . . . . subtract 94 from both sides of the equation

ER = 145

The distance from Erie to Rochester is 145 miles.

Janine is saving money to buy a car. She has a total of $1400 left to save, and she plans to save a certain percentage of $1400

shusha [124]

Answer:

August=$350

September=$560

October=$210

November= $280

Step-by-step explanation:

Total amount left to save $1400.

We calculate the amount save each mount since we are already given the percentages.

For the month of August she saves 25% of $1400, we convert the percentage to equivalent cash

$\frac{25}{100}*1400\\=350$

for the month of August, she saved $350,

Next For the month of September she saves 40% of $1400, we convert the percentage to equivalent cash

$\frac{40}{100}*1400\\=560$

for the month of September, she saved $560,

Next For the month of October she saves 15% of $1400, we convert the percentage to equivalent cash

$\frac{15}{100}*1400\\=210$

for the month of October, she saved $210,

total amount saved by October = $350+$560+$210=$1120

Amount saved by November=1400-1120=$280
