First, you need to find how much an ounce costs. To do that, you have to divide 1.39 by 8. Then you get about 0.17. Now, you multiply 0.17 by 14, and get the answer of 2.38. Therefore, a 14-oz bottle of ketchup costs $2.38.

Cost for 8-oz bottle = $ 1.39

Cost for 1-oz bottle = 8/1.39

= 1.75 ( approx )

Cost for 14-oz bottle of ketchup = 14* cost of 1-oz bottle

= 14* 1.75

=**$ 24.5**

Cost for 14-oz of ketchup bottle is**$ 24.5**

Cost for 1-oz bottle = 8/1.39

= 1.75 ( approx )

Cost for 14-oz bottle of ketchup = 14* cost of 1-oz bottle

= 14* 1.75

=

Cost for 14-oz of ketchup bottle is

Question

What is the fraction 18/24 reduced to its lowest terms? A. 18/24
B. 24/18
C. 3/4
D. 9/12

Solution 1

C. 3/4

To simplify, you find the greatest common multiple of 18 and 24, which is 6. As a result, you divide 18 and 24 by 6. 18 divided by 6 is 3, and 24 divided by 6 is 4. Then you get 3/4 as an answer.

Question

suppose you deposit 1,000 ina savings account that pays interest at an annual rate of 5%. if no money is added or withdrawn from the account answer the following questions. How much money will be in the account after 3 years? How much will be in the account after 18 years? How many years will it take for the account to contain 1,500? How many years will it take for the account to contain 2,000?

Solution 1

After three years: $1000(1+0.05)^3 = $1157.63

Time req'd for amount to reach $1500 from $1000:

1500=1000(1+0.05)^t, or 1.5=1.05^t

Question

Regression equation: y = 3.915(1.106)x the pond can hold 400 water lilies. by what day will the pond be full? write and solve an equation. the pond will be full by the end of day

Solution 1

**Answer:**

46 days

**Step-by-step explanation:**

**Given : **Regression equation:

Where,

y = amount of water lilies the pond hold

3.915 = represents the initial population.

1.106 = represents the increase in population at time x.

x = is a variable of time.

The pond can hold 400 water lilies ⇒ **y=400**

**Putting values in equation **we get,

**Taking log both side **

**By logarithm property **-

Approx.** x=46 **

**Therefore,** 46th day the pond be full.

Solution 2

46 Days

A right triangle has sides measuring 5 inches, 12 inches, and 13 inches. What is the area, in square inches, of this triangle ?

Solution 1

Please look up and apply Heron's Formula. Start by calculating s, where

a + b + c

s = -------------------

2

Then calculate A:

A = sqrt[ s(s-a)(s-b)(s-c) ]

a + b + c

s = -------------------

1. A model rocket is launched from a roof into a large field. The path of the rocket can be modeled by the equation y = –0.04x2 + 8.3x + 4.3, where x is the horizontal distance, in meters, from the starting point on the roof and y is the height, in meters, of the rocket above the ground. How far horizontally from its starting point will the rocket land?
A. 208.02 m
B. 416.30 m
C. 0.52 m
D. 208.19 m
2. A catapult launches a boulder with an upward velocity of 184 ft/s. The height of the boulder (h) in feet after t seconds is given by the function h= -16t^2 + 184t + 20. How long does it take the boulder to reach its maximum height? What is the boulder's maximum height.
A. Reaches a maximum height of 11.6 feet after 5.75 seconded.
B. Reaches a maximum height of 549 feet after 11.5 seconds.
C. Reaches a maximum height of 549 feet after 5.75 seconds.
D. Reaches a maximum height of 23.2 feet after 11.6 seconds.
3. A ball is thrown into the air with an upward velocity of 32 ft/s. Its height (h) in feet after t seconds is given by the function h= -16t^2 + 32t + 6. How long does it take the ball to reach its maximum height? What is the ball’s maximum height? Round to the nearest hundredth, if necessary.
A. Reaches a maximum height of 22 feet after 1.00 second.
B. Reaches a maximum height of 22 feet after 2.00 seconds.
C. Reaches a maximum height of 44 feet after 2.17 seconds.
D. Reaches a maximum height of 11 feet after 2.17 seconds.

Solution 1

The rocket will hit ground level when y = 0. The plan is is to set y =0 and solve the quadratic. Be careful how you go about to this. It is an odd way to represent this kind of problem. The question does say that y defines how far off the ground the rocket is at the beginning. Therefore the height of the building does not matter (or shouldn't). All that matters is that y is ground level when y = 0.

a = - 0.04

b = 8.3

c = 4.3

From here you should be able to calculate the answer. One of them is -0.52 which is not the one you use. Minus heights do not matter in these problems yet. The other root is your answer.

**Problem Two**

Problem two is the usual way to express what happens to a projectile in the air. It again is going to be solved by the quadratic equation.

There are two ways to do this problem. If you know physics, you can solve it using the projectile formulas. If you don't , then you can use the trick in the previous problem. You can calculate how long it takes to hit the ground (h will then be zero).

This problem is rather nasty for someone who has not taken physics. There is another trick. You have to divide the time you get from the previous step by 2. When you solve the quadratic for h = 0, you get 11.6 seconds. But that is the time it takes to hit the ground. Half time is when the boulder will be at it's highest point. t = 11.6 / 2 = 5.8 (which your answers record as 5.75).

h = 0

a= -16

b = 184

c = 20

The answer from this equation is t = 11.6

The time you want is t = 5.75. You can calculate the maximum height by putting 5.75 in for t.

**Problem 3**

Problem 3 is done exactly the same way as problem two. You just have different numbers. When h = 0 the time taken to reach zero = 2.17 seconds. Therefore the time you want to put into the original equation for the maximum height is 1/2 of 2.17 seconds. From there you can find the maximum height.

Note: there is a lot of math in here. I have gotten you past the physics. I have also alluded to the answers. I think you should be able to carry out the rest.

Question

What is the volume of a sphere if the radius is 9?

Solution 1

**Answer: **

**Step-by-step explanation: **To find the volume of a sphere, start with the formula for the volume of a sphere.

Notice that our sphere has a radius of 9 units so we can plug 9 into our formula.

Now, let's simplify the exponent. 9 units³ is equal to 9 units × 9 units × 9 units or 729 units³.

Notice that we can cross cancel in and to and

Question

What is the input to a trigonometric function? a ratio
the x position of a point on the circle
a central angle of a circle
the y position of a point on the circle

Solution 1

**Answer: A central angle of a circle**

**Step-by-step explanation:**

The trigonometric functions are also known as circular functions.

The two fundamental trigonometric functions are defined as the coordinates of a any point A travelling around on the unit circle of radius 1 .

The input variable in trigonometric functions is the central angle of the circle 'x' such that we get sin x and cos x which give the x and y coordinates of A.

**Hence, the input to a trigonometric function is a central angle of a circle.**

Solution 2

The input to a trig function is definitely an angle (whether in degrees or expressed in radians). That angle is also "a central angle of a circle."
