90≤4x+30

Yes she will have enough. 4 multiplied by 18 is 72. 72+30=102. 

Hope this helped.

Answer:

4A + 30 ≥ 90

She will have enough money to take her family to dinner in 4 days.

Step-by-step explanation:

Be

A = Daily gain

B = Money saved = $30

C = Missing days to take the family to dinner = 4 days

D = money needed ≥ $90

The equation would be,

C * A + B ≥ D

4 * A + 30 ≥ 90

4A + 30 ≥ 90

If you earn $18 every day (A = $18), that value is substituted in the inequality, so it is resolved:

4(18) + 30 ≥ 90

72 + 30 ≥ 90

102 ≥ 90

Since the inequality is met, then she will have enough money to take her family to dinner in 4 days.

Hope this helps!

Divide 650 sweets between Cia, Mia and Tia in the proportion 3:4:6. Calculate how many sweets each girl gets.​
vodka [1.7K]

Answer:

150, 200, 300

Step-by-step explanation:

sum the parts of the ratio , 3 + 4 + 6 = 13 parts

divide the total by 13 to find the value of one part of the ratio

650 ÷ 13 = 50 ← value of 1 part of the ratio , then

3 parts = 3 × 50 = 150 ← number of sweets Cia gets

4 parts = 4 × 50 = 200 ← number of sweets Mia gets

6 parts = 6 × 50 = 300 ← number of sweets Tia gets

Identify the domain and range of the inverse of f(x) = 0.5^x.
LekaFEV [45]

Answer:

Domain  (0, ∞)  and Range (-∞, ∞).

Step-by-step explanation:

The domain of f(x) = 0.5^x is all values of x and the range is f(x)>0  as  0.5^x  cannot be negative or zero.

In interval form this is Domain is (-∞, ∞) and Range is  (0, ∞).

So its inverse has Domain  (0, ∞)  and Range (-∞, ∞).
