Next week, Josephine wants: to spend the same total amount of time, but practice the same number of hours each of the 4 days. How many hours would Josephine practice each day? All measurements are rounded to the nearest hour 1/4.
Answer:
The answer is 2 hours
Step-by-step explanation:
First you have to add up all the points which would be;
1 1/2 + 1 1/2+ 2 1/2+ 2 1/2= 8 hours
Next you have to divide by how many points to find AVERAGE;
8 hours divided by 4 points= 2 hours average
So in total, she will practice 2 hours every day

Samantha will attend Lattice College this fall. Tuition for one year is $6,250. Samantha plans to earn $1,500 at her work-study job at the college library. She has a grant for $1,000 and a scholarship that pays $1,200 this year. How much more money will Samantha need for this year's tuition?
Answer:
2,550
Step-by-step explanation:
you are going to add 1,500 + 1,000 + 1,200 = 3,700 then you are going to subtract 6,250-3,700 = 2,550 and that is the answer
Solve for x, round to the nearest tenth. find x x =
Answer:
64.2
Step-by-step explanation:
Use tan to find the measure of x.
tan = 0pposite/adjacent
opposite = 29
adjacent = 14
so:
[tex]tan(x)=29/14\\x = tan^{-1} (29/14)\\x = 64.2[/tex]
Answer:
x = 64.2°
Step-by-step explanation:
tan x° = 29/14
14 · tan x° = 29
tan x° = 29/14
arctan(x) = 64.2°

Shown below is a prism.
The cross-sectional area is 21cm2.
The prism has a length of 6cm.
Find the volume of the prism.
Answer:
Volume = 126 cm^2
Step-by-step explanation:
You don't exactly know what the base looks like, but it doesn't matter. The volume of a Prism is Base * height.
Solution
V = Base (which is the Cross sectional Area) * Length
V = 21 cm^2 * 6 cm
V = 126 cm^2
The dollar value v (t) of a certain car model that is t years old is given by the following exponential function.
v (t) = 19,900(0.86)^t
Find the initial value of the car and the value after 11 years.
Round your answers to the nearest dollar as necessary.
Answer:
v(0) = 19,900, v(11) = 3,787.36
Step-by-step explanation:
v(0) = 19,900 (0.86)^0 = 19,900 * 1 = 19,000
v(11) = 19,900 (0.86)^11 = 19,900 * 0.190319 = 3,787.36
A deck of 40 cards contains 20 blue and 20 red cards. Each color has cards numbered 1 to 20.
Which events are independent? Choose all that apply.
Answer:
A red 5 is chosen from the deck. The card is put back into the deck and the a red card is chosen.
Step-by-step explanation:
An independent event is one whose outcome is not dependent on any other event. There are two types of cards in the deck. If a red card is selected it will be from the series 1 - 20, if the card is put back into deck and then again a red card is selected it will be again from the series 1 - 20. This is an independent event since its outcome is same irrespective of the events.
This is an independent event since its outcome is the same irrespective of the events.
What are independent and dependent variables?Even though everything can be almost always related to its reason, when we talk about two related things, there might happen that one of those things is dependent on the other.
If a variable is taking its values independently of any visible direct cause, then that variable is called an independent variable.
The variables that take their values based on some other variables' values are called dependent variables.
A deck of 40 cards contains 20 blue and 20 red cards. Each color has cards numbered 1 to 20.
This is an independent event since its outcome is the same irrespective of the events.

the Gonzales family has three children on summer break they went to an amusement park they bought 3 children tickets for 18.50 and 2 adults tickets if they spent a total of 104.50 how much was the price of the parents
(a) write an equation to represent this situation use x to represent the price of each adult tickets
(b) how much was the price each adult tickets
Answer:
a. 18.50 + x = 104.50
b. x = 86
Step-by-step explanation:
To get the price of the adult tickets use inverse operation and subtract 18.50 on both sides. When you subtract 18.50 from 104.50 you should get 86. so x = 86.

A new car loan has monthly payments of $482.75. How much money will be paid on the car loan after 3 years?
========================================================
Work Shown:
1 year = 12 months
3*(1 year) = 3*(12 months) ..... multiply both sides by 3
3 years = 36 months
You'll make 36 payments, each being $482.75, which means the total amount of money paid is 36*482.75 = 17,379 dollars
