Answer:

8.95

Step-by-step explanation:

Convert 12% into a decimal by dividing 12 by 100 to get 0.12. To find 12% of 7.99, multiply it by 0.12. However, since we want to know the total cost of the meal after the markup, an eaiser way is to multiply 7.99 x 1.12 (the 1 represents the original price of meal, since we are adding on to it). This is the more effective way to solve this, but another way would just be to take the result of 7.99 x 0.12 and add it to 7.99.

Note that the actual answer is 8.9488, but I rounded to the nearest hundreth.

Juli2301 [7.4K]

Answer:

After 14.92 seconds, the arrow hits the ground.

Step-by-step explanation:

Given:

Initial velocity of the arrow is, u=240\ ft/s or 73.152\ m/s

The arrow goes up and come back to the same starting position. So, initial position is same as that of final position.

Therefore, displacement of the arrow is 0 m.

The displacement of the arrow is given as:

s=ut-\frac{1}{2}gt^{2}   (equation 1)

Plug all value in equation 1 and solve for t

0=73.152\timests t-\frac{1}{2} \times9.8 \times t^{2}

0=73.152\timests t-4.9 \times t^{2}

0=t(73.152-4.9 \times t)

73.152-4.9\times t=0     where t\neq 0

4.9\times t=73.152

t=\frac{73.152}{4.9}= 14.92\ s

∴ After 14.92 seconds, the arrow hits the ground.

A picture is 6 inches longer than it is wide and has an area of 167
Scorpion4ik [409]

Answer:

A) L = W + 6

B) L * W = 167  OR L = 167 / W

Substituting B) into A)

167 / W = W + 6

Multiplying both sides by "W" we get

167 = W^2 + 6W

W^2 + 6W -167

Solving by the quadratic formula

Width = 10.266

Length = 16.266

Help! how can i determine the range
djverab [1.8K]

Answer:

[-1,\infty)

Step-by-step explanation:

Remember that the range is the set of all y-values. Thus, since the minimum of the function is y=-1, then our range is [-1,\infty). In interval notation, we use brackets to show what's included and parentheses to show what's not included.
