Sam will take four science tests this quarter. Her scores on three of the tests are shown below.
What does Sam need to score on the fourth test to ensure that she will have an average of 90% for all four tests?
Answer:
98%
Step-by-step explanation:
Test 1 - 83%
Test 2 - 91%
Test 3 - 88%
Test 4 - ?
If we use x to represent Test 4, we can create the following equation:
1/4 (83 + 91 + 88 + x) = 90
We find the average here by adding up the four test scores and dividing by 4.
Proceed to solve it:
1/4 (262 + x) = 90
262 + x = 360
x = 98
Therefore, Sam needs to get a 98% to have and average of 90% on all four tests.

Daryll is given $30 and spends $1.25 per day on basketball cards. On the same day, Larry is given $2 and saves $1.25 per day. The graph shows the amount of money each boy has compared to the number of days that have passed.
How much money will each boy have on the day that the boys have the same amount of money?
$11.20
$30.00
$2.00
$16.00
The boys have $16 on 11th day.
What is Graph?The graph is simply a structured representation of the data. It aids in our comprehension of the data. The numerical information gathered through observation is referred to as data.
Following the creation of a research question, data is continuously gathered through observation. The information is subsequently arranged, condensed, categorised, and visually portrayed.
In a line graph, the information or data is represented as a series of markers, or dots, and is then connected to one another by a straight line.
Usually, data that varies over time is represented with a line graph.
Given:
Daryll is given $30 and spends $1.25 per day on basketball cards.
Larry is given $2 and saves $1.25 per day.
So, to find the same day for both from the graph.
We have to focus on where the lines for two persons intersects, it will the on same day how much money they have.
Hence, the boys have $16 on 11th day.

A tepee is designed to have a diameter of 10 feet and a volume of 366 feet at what h Igor should the support poles cross to assemble the tepee (round ur answer to the nearest foot)
Answer:
A. 14ft
Step-by-step explanation:
First get the cones volume formula v=(3.14*r^2*h)/3
Second find the radius which is 1/2 the diameter.
Third plug in given and solve 366= (3.14*5^2*h)/3
366*3=3*(3.14*25*h)/3
1098=78.5h
1098/78.5=78.5h/78.5
13.987=h
