Answer:

3rd Option

Step-by-step explanation:

Which equation is the inverse of y = 7x2 – 10?

y = StartFraction plus-or-minus StartRoot x + 10 EndRoot Over 7 EndFraction

y = plus-or-minus StartRoot StartFraction x + 10 Over 7 EndFraction EndRoot

x = plus-or-minus StartRoot StartFraction x Over 7 EndFraction + 10 EndRoot

y = StartFraction plus-or-minus StartRoot x EndRoot Over 7 EndFraction plus-or-minus StartFraction StartRoot 10 EndRoot Over 7 EndFraction

Resource Allocation You manage an ice cream factory that makes two flavors: Creamy Vanilla and Continental Mocha. Into each quar
vovikov84 [41]

Answer:

in order to use up all the eggs and cream, the number of quarts of each flavor that should be made is;

Creamy vanilla x = 200 quarts

Continental mocha y = 100 quarts

Step-by-step explanation:

Let x and y represent the number of quarts of Creamy Vanilla and Continental Mocha that should be made in order to use up all the eggs and cream respectively.

For Creamy Vanilla go 2 eggs and 3 cups of cream

For Continental Mocha go 1 egg and 3 cups of cream.

Total number of eggs = 500 eggs

Total number of cream cups = 900 cups.

For the eggs;

2 eggs × x + 1 egg × y = 500

2x + y = 500 .......1

For the cream cups;

3 cups × x + 3 cups × y = 900

3x + 3y = 900

Dividing through by 3

x + y = 300 .......2

Solving the simultaneous equation;

Subtracting equation 2 from 1

(2x + y) - (x+y) = 500-300

2x -x = 200

x = 200

Substituting x = 200 into equation 2;

200 + y = 300

y = 300 - 200

y = 100

Therefore, in order to use up all the eggs and cream, the number of quarts of each flavor that should be made is;

Creamy vanilla x = 200 quarts

Continental mocha y = 100 quarts

Puis traveled one-quarter of the journey to his destination. He still has to cover 24km to reach the third-way mark. How many ki
sertanlavr [38]

Answer:

The distance Puis still have to travel to reach his destination is 72 km.

Step-by-step explanation:

The given parameters about Puis journey are

Distance covered by Puis = 1/4 of total distance

Distance remaining for Puis to complete the journey = 3/4 of the journey

Distance of Puis from the third-way (central) mark = 24 km

Therefore;

Distance from 1/4 of journey to 1/2 of journey = 24 km

Hence, 1/2 - 1/4 = 1/4 of the journey = 24 km

Which gives Total distance covered by Puis = 24 km

Total distance of the journey = 4 × 24 km = 96 km

The distance Puis still have to travel to reach his destination = 96 - 24 = 72 km.

iren [92.7K]

Answer:

23.75

Step-by-step explanation:

There is 2 adults and adult tickets cost $5.50 so we do

5.50 x 2 = 11

Now we have to find student tickets and we can see we have 3 so we do

4.25 x 3 = 12.75

so then we add them all up

11 + 12.75

which we will get 23.75
