How long will it take a plane to fly 183 miles at 122 miles per hour
Answer:
Total time = 1.5 hours
Step-by-step explanation:
Given:
Total distance = 183 miles
Speed = 122 miles per hour
Find:
Total time
Computation:
Total time = Total distance / Speed
Total time = 183 / 122
Total time = 1.5 hours
For f(x) = -7x + 14, evaluate f(3)
Answer:
f(3) = -7
Step-by-step explanation:
f(3) = -7(3) + 14

f(3) = -7
Elaisha has her grandmother's amazing cooking recipes. She earns money by baking cupcakes for a local bakery. She gets $15 for each dozen cupcakes. If Elaisha does 8 dozen cupcakes in one week, how much will Elaisha earn?
Answer:
$120
Step-by-step explanation:
If she gets $15 per dozen, and if she does 8 dozens, we need to multiply 15 by 8. When we do this, we get 120. This means Elaisha earns $120.
Answer:
120 a week

if a person walks 1/2 mile in 1/4 hour, how far does that person walk in 1 3/4 hours at that rate?
Answer:
3 1/2 miles
Step-by-step explanation:
We can use a ratio to solve
1/2 mile x miles
----------------= ---------------
1/4 hour 1 3/4 hours
Changing to improper fractions
1/2 mile x miles
----------------= ---------------
1/4 hour 7/4 hours
Using cross products
1/2 * 7/4 = 1/4x
7/8 = 1/4x
Multiply each side by 4
7/2 = x
Changing back to a mixed number
3 1/2 =x
please help me out! express the inequality using interval notation
Answer:
(7, ∞)
Step-by-step explanation:
Because x does not equal 7 as well, brackets won't be used here.
Because x can be any number greater than 7, this means the domain includes positive ∞.
Louisa states that the solution to the equation One-fourth x minus 3 = StartFraction 3 Over 8 EndFraction x + 4 is x = 56. She verifies her solution using the steps below.
Equation: One-fourth x minus 3 = StartFraction 3 Over 8 EndFraction x + 4
Step 1: One-fourth (56) minus 3 = StartFraction 3 Over 8 EndFraction (56) + 4
Step 2: 14 minus 3 = 21 + 4
Step 3: 11 = 25
Which statement most accurately describes Louisa’s error?
Louisa made an error when determining the original solution of x = 56.
Louisa made an error when substituting the solution in for x.
Louisa made an error when multiplying 56 by One-fourth and by StartFraction 3 Over 8 EndFraction.
Louisa made an error when adding or subtracting.

Step-by-step explanation:
A family of four drove from San Francisco to New York. They drove the same number of miles each 6 days. How many miles did they drive each day? How can you interpret the remainder?
Answer:
Step-by-step explanation:
Approximate distance between San Francisco and New York = 2903 miles
Number of family members = 4
Approximate distance to be covered by each member per day = [tex]\frac{2903}{4}[/tex] = [tex]725\frac{3}{4}[/tex] miles
Number of days to drive = 6 days
Total distance to be covered by each member each day = [tex]\frac{2903}{4}\times \frac{1}{6}[/tex]
= [tex]\frac{2903}{24}[/tex]
= [tex]120\frac{23}{24}[/tex] miles
Therefore, each family member has to drive the car for 120 miles per day approximately.
23 miles remaining will be covered by any one of the family members on the last day.

how do you calculate the profit
Answer:
total money - total expences = profit
Total money is the money you make, so say you made $50
Total expences is how much you paid to have that thing made, say $10
50 - 10 = 40
the profit would then be $40

Two sides of an obtuse triangle measure 12 inches and 14 inches. The longest side measures 14 inches.
What is the greatest possible whole-number length of the unknown side?
2 inches
3 inches
7 inches

The greatest possible whole-number length of the unknown side is 9 inches, option fourth is correct.
What is the triangle?The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have:
Two sides of an obtuse triangle measure 12 inches and 14 inches. The longest side measures 14 inches.
As we know, in the triangle, the sum of the two sides is equal and greater than the third side.
Mathematically,
x + y ≥ z
Here x, y, and z are the sides of the triangle.
12 + 14 ≥ x
x ≤ 26
The greatest possible whole-number length of the unknown side is 9 inches.
Thus, the greatest possible whole-number length of the unknown side is 9 inches, option fourth is correct.

What is the value of x in the equation 6(x +11)= -300?
Answer:
-61
Step-by-step explanation:
We use the distributive property to distribute 6 to both x and 11. This gives 6x+66=-300. Subtracting both sides by 66 gives 6x=-366. Dividing both sides gives x=-61.
