Answer:

We can get 94 donuts

Step-by-step explanation:

We have 50 dollars

They charge 3.00 to box the donuts and .50 per donut

The total cost is 3 for the box and .50 per donut * the number of donuts

50 = 3+.5d  where d is the number of donuts

Subtract 3 from each side

50-3 = 3-3+.5d

47 = .5d

Divide each side by .5

47/.5 = .5d/.5

94 =d

We can get 94 donuts

Please help me with this question
Veronika [31]

Answer:

Since we have g(4) just replace every x with 4:

g(4) = (4² -6)/(3×4 + 10)

      = (16 - 6)/(12 + 10)

      = 10/22 = 5/11

The base of a triangle is 3 more than 2 times of height. Determine the dimensions that give total area of 10 square feet.
Alona [7]

Answer:

height = 2.5 ft , base = 8 ft

Step-by-step explanation:

the area (A) of a triangle is calculated as

A = \frac{1}{2} bh ( b is the base and h the height )

height = h then base = 2h + 3 and A = 10 , then

\frac{1}{2} h(h + 3) = 10 ( multiply both sides by 2 to clear the fraction )

h(h + 3) = 20 , that is

h² + 3h = 20 ( subtract 20 from both sides )

h² + 3h - 20 = 0 ← in standard form

(h + 4)(2h - 5) = 0 ← in factored form

equate each factor to zero and solve for h

h + 4 = 0 ⇒ h = - 4

2h - 5 = 0 ⇒ 2h = 5 ⇒ h = 2.5

but h > 0 , then h = 2.5

and 2h + 3 = 2(2.5) + 3 = 5 + 3 = 8

that is height = 2.5 ft and base = 8 ft

You have a 10kg bag of sand. The mass of a grain of sand is about 10 to the -3 power gram. About how many grains of sand are in
Anika [276]
10 kg* (1000 g/ 1 kg)* (1 grain of sand/ 10^(-3) g)= 10^7 grains of sand.
(Note that the units cancel out so you get the answer)

The final answer is 10^7 grains of sand.
