Sharonda uses a blend of dark chocolate and milk chocolate to make the ice cream topping at her restaurant. She needs to buy 120
White raven [17]

Step-by-step explanation:

ATQ,

Let d be the number of kilograms of dark chocolate she buys and m be the number of kilograms of milk chocolate she buys.

She needs to buy 120 kg of chocolate in total for her next order, and her recipe calls for twice the amount of dark chocolate as milk chocolate.

So,

m = 2d .....(1)

m + d = 120 ...(2)

We can also solve the above equations,

Put m = 2d in equation (2)

2d + d = 120

3d=120

d = 40

Put d = 40 in equation (1)

m = 2(40)

m = 80

Hence, she will need 40 kg of dark chocolate and 80 kg of milk chocolate.

PLEASE HURRY WILL MARK AS BRAINLIESTV
Alenkasestr [34]

Answer:

<u>There are two inequalities that represent the total number of </u>

<u>balloons, b, they can purchase and not spend over their budgeted amount:</u>

<u>0.65b ≤ 70</u>

<u>0.65b + 225 ≤ 295</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Budget to plan the event = $ 295

Expenses on supplies so far = $ 225

Cost of each balloon = $ 0.65

2. Which of the following inequalities represents the total number of

balloons, b, they can purchase and not spend over their budgeted amount?

1. Let's find how much of the budget is still available:

Budget available = Budget to plan the event - Expenses on supplies so far

Budget available = 295 - 225

Budget available = $ 70

2. Let's find the inequality that represents the total number of

balloons, b, they can purchase and not spend over their budgeted amount.

Number of balloons ≤ Budget available/Cost of each balloon

Replacing with the values we know, we have:

b ≤ 70/0.65

<u>0.65b ≤ 70</u>

or we can write it also including the total budget this way:

Number of balloons  ≤ Budget to plan the event - Expenses on supplies so far /Cost of each balloon

Replacing with the values we know, we have:

b ≤ (295 - 225)/0.65

0.65b ≤ 295 - 225

<u>0.65b + 225 ≤ 295</u>

If the length of a rectangular field is 12ft less than 6 times it’s width, and perimeter is 158.
GarryVolchara [31]

Answer:

Therefore the Dimensions of Rectangular field are

Length=66\ feet\\Width=13\ feet

Step-by-step explanation:

Given:

Let the length of the Rectangular field be ' L '

and Width be 'W'

According to given Condition

L=6W-12

Perimeter = 158 ft

To Find:

L = ?

W = ?

Solution:

Perimeter of Rectangle is given as

Perimeter=2\times L+2\times W

Substitute 'L' and Perimeter we get

158=2\times (6W-12)+2W=12W-24+2W\\\\14W=158+24=182\\\\W=\dfrac{182}{14}=13\ feet

Substitute 'W' in L we get

L=6\times 13-12=66

Therefore the Dimensions of Rectangular field are

Length=66\ feet\\Width=13\ feet

diamong [38]

Pattern : Multiply by -4 to get to the next number
3 x (-4) = -12
-12 x (-4) = 48
To get to the 6th term : 3 x (-4)^5 = 3 x (-1024) = -3072
