jan has a 12-ounce milkshake.Four ounces in the milkshake are vanilla,and the rest is chocolate.What are two equivalent fractions that represent the fraction of the milkshake that is vanilla
Answer:
In this item, we are given that out of 12 ounces of ingredients comprising the milkshake, there are 4 ounces vanilla. Expressing this into fraction will give us an answer of 4/12. This fraction can be one of the answers. Since we are asked for two fractions, we can simplify 4/12 such that we get an equivalent fraction that is equal to 2/6. Hence, the answers to this question are 4/12 and 2/6.

Pls help!!! Pls and thank you!! So much
Answer:
I solved it for u!
Hope it helps
Step-by-step explanation:
Another way, it an isosceles triangle so the base will be same, so angle 3 and angle 1 will be same after u find angle 3, then angle 1 will be equal to it
So here angle 3 = 64°
So angle 1= 64°
someone pls help asap this is due tmrw !!
x - 3y = -12
2x + 3y = 3
Answer:
Step-by-step explanation:
to solve this system of equations we will add them
x-3y=-12
2x+3y=3 now +3y-3y=0
3x=-12+3
3x=-9
x=-3
plug in the first equation
-3-3y=-12
-3y=-12+3
-3y=-9
y=3
My wife however did bake cookies this year 40% of the cookies she baked chocolate chip if she baked 36 chocolate chip cookies how many total cookies does she bake
Answer:
The total number of cookies is 90
Step-by-step explanation:
As, they said 40% of the total number of cookies is 36, we will take the total as "x"
= 40% of x = 36
40/100 X x = 36
40x = 36 x 100
40x = 3600
x = 3600/40
x = 90
So total cookies she baked = 90
Let's check!
So 40% of 90 need to be 36
So,
40/100 x 90 = 3600/100
= 36
So therefore, total number of cookies = 90

Zachary places daisies and magnolias in a vase. If daisies cost x dollars, magnolias cost y dollars and a vase costs v dollars, mark all equations which represent the cost of 20 vases of 40 daisies and 80 magnolias.
Answer:
[tex]Total = 20v + 40x + 80y[/tex]
[tex]Total = 20(v + 2x + 4y)[/tex]
Step-by-step explanation:
The options were not given,en but the question can still be solved.
Given
[tex]Daises = \$ x[/tex]
[tex]Magnolias = \$ y[/tex]
[tex]Vase = \$ v[/tex]
Required
Determine the cost of 20 vases, 40 daises and 80 magnolias
If 1 vase costs $v, then
[tex]20\ vases = 20 * v[/tex]
[tex]20\ vases = 20v[/tex]
If 1 daises costs $x, then
[tex]40\ daises = 40 * x[/tex]
[tex]40\ daises = 40x[/tex]
If 1 magnolias costs $y, then
[tex]80\ magnolias = 80 * y[/tex]
[tex]80\ magnolias = 80y[/tex]
[tex]Total = 20v + 40x + 80y[/tex]
Another expression that represents the total is to factorize the expression.
[tex]Total = 20(v + 2x + 4y)[/tex]
Write an equation and solve for x.
That's the final Answer, and don't worry about the answer in point form. I worked it out correctly. All steps followed;

PLS HELP WILL GIVE BRAINLIEST
Answer:
Step-by-step explanation:
For number 1.
If x = -2.
y = 4x + 3 = 4(-2) + 3 = -8 + 3 = -5
If x = 3
y = 4x + 3 = 4(3) + 3 = 12 + 3 = 15
If x = -4
y = 4x + 3 = 4(-4) + 3 = -16 + 3 = -13
If x = -5
y = 4x + 3 = 4(-5) + 3 = -20 + 3 = -17
If x = 5
y = 4(x) + 3 = 4(5) + 3 = 20 + 3 = 23
For number 2.
If x = -2
[tex]y = x^{2} + 4 + 2x = (-2)^{2} + 4 + 2(-2) = 4 + 4 - 4 = 4[/tex]
If x = 3
[tex]y = x^{2} + 4 + 2x = (3)^{2} + 4 + 2(3) = 9 + 4 + 6 = 19[/tex]
If x = -3
[tex]y = x^{2} + 4 + 2x = (-3)^{2} + 4 + 2(-3) = 9 + 4 - 6 = 7[/tex]
If x = 4
[tex]y = x^{2} + 4 + 2x = (4)^{2} + 4 + 2(4) = 16 + 4 + 8 = 28[/tex]
If x = -4
[tex]y = x^{2} + 4 + 2x = (-4)^{2} + 4 + 2(-4) = 16 + 4 -8 = 12[/tex]

What is the area of the football field in the scale drawing? Assume that the field is shaped like a rectangle.
Answer:
i mean might as well get free points now that its 2 weeks old
Step-by-step explanation:
Answer:
Pythagorean Theorem: the diagonal of the football field is the hypotenuse. Let´s say the diagonal is C and the two other sides are A and B.
Width = A
Length = B
Diagonal = C
so: a2+b2=c
2502+1002=c2
2500+10000=c2
12500=c2
c=√12500
c=111.80 yards

Given a triangle ABC has angles of A = 30 and B = 70, what is the smallest side?
Answer:
A=30 is the smallest side
Step-by-step explanation:
A+B+C= 180
30+70+C=180
100+C=180
C=180-100
C=80
Therefore, A=30 is the smallest side of the triangle...

The amount of water (in liters) in tank 1 after t minutes is 30t + 25. The amount of water (in liters) in tank 2 after t minutes is −20t + 1000. Find the time when the amount of water will be equal.
Answer:
The water amount will be equal at 19.5 minutes
Step-by-step explanation:
Here, we want to find the value of t when the water level in both tanks will be equal
We simply proceed to equate both ;
That will be;
30t + 25 = -20t + 1000
30t + 20t = 1000-25
50t = 975
t = 975/50
t = 19.5 minutes
Can I get some help with this is the Last question
Answer:
x = 11
Step-by-step explanation:
Here, we want to get the value of x
Let’s start by looking at the point U
Now, we can see angles on a straight line at that point
Mathematically, angles on a straight line are supplementary
What this mean is that they add up to 180
Now, the value of the angle that falls into the triangle on that straight line will be;
180-(11x + 12)
Now, we have all the angles of the triangle
Mathematically, the sum of all is 180 as the a sum of the angles of a triangle is 180
5x + 10 + 58 + 180-(11x+2 )= 180
5x + 10 + 58 -11x-2 = 0
-6x+ 66 = 0
6x = 66
x = 66/6
x = 11

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
