Answer:
Quantité totale d'essence consommée: 167 litres (arrondie à l'unité pres)
Nombre de jours du voyage: 12 jours (je pense! Je ne comprends pas "jours sants" ? Suivants? )
Distance parcourue pour aller à Pittsburgh: 1269.8 km
coût total de l'essence: $ 204.11
Coût moyen de l'essence consommée par jour (arrondi au centieme pres): $17.01
Distance parcourue par jour pour le retour: 613.5 km
Distance totale parcourue durant les vacances: 2496.8 km
Step-by-step explanation:
Jour 1 Montreal à Parc Sandbanks
2,3,4,5 Parc Provincal Sandbanks
6,7,8,9,10 Pittsburgh
11,12 Pittsburgh à Quebec
Distance: ajouter les numéros jours par jour.
Essence consommée: 6.7 litres pre 100, donc diviser la distance totale par 100 puis multiplier par litres par km
2496.8/100 = 24.968 × 6.7 = 167.2856 et arrondir le total: 167.3
Coût total de l'essence: Il faut multiplier le total consommée par la coût par litre, $1.22 167.3×1.22 = $204.11
Coût moyen de l'essence consommée par jour: $204.11 ÷ 12 jours = $17.01/jour
Distance parcourue par jour pour le retour: 1227km/2days = 613.5 km/jour
Distance totale parcourue durant les vacances: Ajoutez les distances journalières parcourues à Pittsburgh à la distance de retour à Quebec.
1269.8 + 1227 = 2469.8 km

You earn $28 for washing 4 cars. How much do you earn for washing 3 cars?
Answer:
21 dollars
Step-by-step explanation:
Answer:
$21
Step-by-step explanation:
Make the original statement into a ratio.
$28/4
Simplify the fraction above.
$28/4 = 7
So, you earn $7 per car you wash.
As a result, you multiply $7 by the number of cars the question is asking you for. In this case it is 3 cars.
So, you multiply 7 x 3
7 x 3 = 21
Therefore, you will earn $21 for washing 3 cars.

A map is drawn using a scale of 1cm/80 mi
Two cities are 280 miles apart
How far apart are the cities on the map?
Answer:
280/80 = 28/8 = 7/2 = 3.5 cm
Step-by-step explanation:
the ratio is 1cm/80mi = a cm/280mi
so you get 280cm * mi = 80mi*a cm
so a = 280/80 = 3.5

Plot the points (-3, 4)(−3,4)left parenthesis, minus, 3, comma, 4, right parenthesis and (4, 4)(4,4)left parenthesis, 4, comma, 4, right parenthesis on the coordinate plane below
Answer:
The image shows the points on a coordinate axis.
Step-by-step explanation:
The first point is [tex](-3,4)[/tex].
This means that the point on the [tex]x[/tex] axis is [tex]-3[/tex] and [tex]y[/tex] axis is [tex]4[/tex]. The point is in the second quadrant.
The second point is [tex](4,4)[/tex].
This means that the point on the [tex]x[/tex] axis is [tex]4[/tex] and [tex]y[/tex] axis is [tex]4[/tex]. The point is in the first quadrant.
The image shows the points on a coordinate axis.

Find the measurement of the following angle.
Plz I need help
Answer:
<ABC = 51°
Step-by-step explanation:
Given
<A = 2x -15°
<B = x - 5°
< C = 148°
Now
<A + <B = < C ( Exterior angle of a triangle is equal to the sum of two opposite interior angles)
2x -15° + x - 5° = 148°
3x - 20° = 148°
3x = 148° +20°
3x = 168°
x = 168° / 3
X = 56°
Now for Angle B
= 56° - 5°
= 51°
Hope it helps :)
What are the solutions to 7x^2 + 10x -3 = x^2 + 3x?
Answer:
x=(1)/(3),-(3)/(2)
Step-by-step explanation:
Answer:
(- 3/2, 1/3)
Step-by-step explanation:
7x^2+10x-3=x^2+3x
7x^2+10x-3-x^2-3x=0
6x^2+7x-3=0
6x^2+9x-2x-3=0
3x x (2x+3)-(2x+3)=0
(2x+3)x(3x-1)=0
2x+3=0
3x-1=0
x1=- 3/2
x2= 1/3

given h(x) =2x+2, solve for x when h(x) =4
Answer:
x = 1
Step-by-step explanation:
h(x) =2x+2 h(x) = 4
4 = 2x + 2
4 - 2 = 2x
2 = 2x
x = 2/2
x = 1

A triangle on a coordinate plane is translated according to the rule T-3,56%, y). Which is another way to write this
rule?
(x, y) - (x-3, y + 5)
(x, y) - (x-3, y-5)
(x, y) - (x + 3. y-5)
(x, y) - (x + 3, y + 5)
Given:
Consider the rule of translation of a triangle is [tex]T_{(-3,5)}(x,y)[/tex].
To find:
The another way to write this rule.
Solution:
We have, the rule of translation [tex]T_{(-3,5)}(x,y)[/tex].
We know that [tex]T_{(a,b)}(x,y)[/tex] is defined as
[tex](x,y)\to (x+a,y+b)[/tex]
So, [tex]T_{(-3,5)}(x,y)[/tex] can be defined as
[tex](x,y)\to (x+(-3),y+(5))[/tex]
[tex](x,y)\to (x-3,y+5)[/tex]
It means, the triangle is translated 3 units left and 5 units up.
Therefore, the correct option is A.
Answer:
A

What is the vertex of the function defined as
g(x) = f(x – 5) + 3?
Answer:
f=gx−3/x−5
Step-by-step explanation:
Step 1: Flip the equation.
fx−5f+3=gx
Step 2: Add -3 to both sides.
fx−5f+3+−3=gx+−3
fx−5f=gx−3
Step 3: Factor out variable f.
f(x−5)=gx−3
Step 4: Divide both sides by x-5.
f(x−5)/x−5=gx−3/x−5

A group of friends is going to a baseball game. A general admission ticket to the game costs $9.00. A ticket for a fan club member costs $6.00. The expression 9x + 6y models the cost for the entire group of friends. Which is the meaning of the term, 9x?
Answer:
See explanation!
Step-by-step explanation:
The term 9x is comprised of two values: 9 and x. The 9 represents the cost of the general admission tickets. Since the expression is representing the total cost for the group of friends, the number of friends attending must be represented somehow in the equation. Since the $9 is paired with the x, this means that x represents how many of the friends are paying the general admission price. After interpreting both values within the term, the meaning of the term 9x is simply just the total cost of the friends that are paying the general admission price! Hope this helps!

у+ 4 = -4(х+2) what is this in standard form?
Answer:
4x + y = -12
Step-by-step explanation:
Standard form is Ax + By = C
First, distribute the -4:
у + 4 = -4(х + 2)
y + 4 = -4x - 8
Subtract 4 from both sides:
y = -4x - 12
Add 4x to both sides:
4x + y = -12
So, the standard form equation is 4x + y = -12
