Tim made 10 baskets during a basketball game. Each basket was worth either 2 or 3 points. How many different numbers could represent the total points scored by Jordan?
The total point is an illustration of arrangements
There are 6 different numbers that could the total points scored by Jordan
How to determine the number of total points?The different number (n) that can represent the total point is calculated as:
n = 2 points + 3 points + 1
Remove the units
n = 2 + 3 + 1
Evaluate the sum
n = 6
Hence, there are 6 different numbers that could the total points scored by Jordan?

Answer:
x = [tex]\sqrt{15}[/tex]
Step-by-step explanation:
Since 2 sides are equal then triangle is isosceles and the segment from the vertex is a perpendicular bisector.
Th triangle is divided into 2 right triangles with legs x and 7 and hypotenuse 8
Using Pythagoras' identity, then
x² + 7² = 8²
x² + 49 = 64 ( subtract 49 from both sides )
x² = 15 ( take square root of both sides )
x = [tex]\sqrt{15}[/tex]
Number line, and point Y partitions line XZ into two parts so that the ratio of the length of line segment XY to the length of line segment YZ is 1:4. The coordinate of X is 1.3, and the coordinate of Y is 3.8. What is the coordinate of Z? Show all work
Answer:
13.8
Step-by-step explanation:
If Points X and Z are on a number line and point Y partition line XZ into two parts where XY: YZ = 1:4, this can be expressed as;
XY/YZ = 1/4
cross multiply;
YZ = 4XY
Also, if the coordinate of X is 1.3, and the coordinate of Y is 3.8, then the distance XY will be expressed as XY = 3.8 - 1.3
XY = 2.5
YZ = 4(2.5)
YZ = 10
Since Y is at 3.8 and YZ is 10, then coordinate Z will be YZ + Y
coordinate of Z = 10+3.8
coordinate of Z = 13.8

Is 8397 divisible by 9 ? Explain your answer
Answer:
Yes
Step-by-step explanation:
9 can go into 8397 evenly without any remainders.
Answer:
8397/9= 933
8397 is divisible by 9 if you divide 8397 by 9 and the quotient is an integer. The easiest way to determine if 8397 is divisible by 9 is to calculate the sum of the digits in 8397. If the sum of the digits is divisible by 9, then 8397 is divisible by 9.
8+3+9+7= 27

What is Trigonometry?The area of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc).
Given:
H= 25
P = 24
Now, Base, B= √H² - P²
B= √25² - 24²
B= √625- 576
B= 7
Now, tan [tex]\theta[/tex] = P/ B
= 24/ 7
Hence, the value for the tan [tex]\theta[/tex] is 24/7.

prove that 1-tan^2x/1+tan^2x=2cos^2x-1
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
tan x = [tex]\frac{sinx}{cosx}[/tex] , sin²x + cos²x = 1
Consider the left side
[tex]\frac{1-tan^2x}{1+tan^2x}[/tex]
= [tex]\frac{1-\frac{sin^2x}{cos^2x} }{1+\frac{sin^2x}{cos^2x} }[/tex] ← multiply numerator/ denominator of the whole fraction by cos²x
= [tex]\frac{cos^2x-sin^2x}{cos^2x+sin^2x}[/tex]
= [tex]\frac{cos^2x-sin^2x}{1}[/tex]
= cos²x - sin²x
= cos²x - (1 - cos²x)
= cos²x - 1 + cos²x
= 2cos²x - 1
= right side , thus proven
[tex]\frac{1 - \tan^2(x)}{1 + \tan^2(x)}\\= \frac{\frac{\cos^2(x)}{\cos^2(x)} - \frac{\sin^2(x)}{\cos^2(x)}}{\frac{\cos^2(x)}{\cos^2(x)} + \frac{\sin^2(x)}{\cos^2(x)}}\\= \frac{\frac{\cos^2(x) - \sin^2(x)}{\cos^2(x)}}{\frac{\cos^2(x) + \sin^2(x)}{\cos^2(x)}}\\= \frac{\cos^2(x) - \sin^2(x)}{\cos^2(x)} \cdot \frac{\cos^2(x)}{\cos^2(x) + \sin^2(x)}\\= \frac{(\cos^2(x) - \sin^2(x)) \cdot \cos^2(x)}{\cos^2(x) \cdot (\cos^2(x) + \sin^2(x))}\\= \frac{\cos^2(x) - \sin^2(x)}{\cos^2(x) + \sin^2(x)}[/tex]
[tex]= \cos^2(x) - \sin^2(x)\\= \cos^2(x) - (1 - \cos^2(x))\\= \cos^2(x) - 1 + \cos^2(x)\\= 2\cos^2(x) - 1[/tex]

Find the equation of the straight line passing through the point (0, 5) which is perpendicular to the line y=1/6x+2
Hey there!
Perpendicular lines have slopes that are opposite reciprocals. This means we take a number, flop it over, and change its sign.
In this case, the slope is 1/6.
First, flop it over:
6/1 (or just 6)
Then, change its sign:
-6
Now, the line passes through the point (0, 5)
The reason 5 is highlighted is because it's the y-intercept of 5.
So we have the Slope & the Intercept.
See what I mean? Yeah! We can write the line's equation in Slope-Intercept Form (y=mx+b)
In this formula, m stands for the slope, and b stands for the y-intercept.
In this case, -6 is the slope, and 5 is the y-intercept.
Hence, the equation is
[tex]\boxed{\boxed{\bold{y=-6x+5}}}[/tex]
Hope everything is clear.

1750 litres of petrol is required to fill the tanks of 50 cars. If 1960 litres of petrol is available, how many more cars can be filled?
1750 litres.............50 cars
1960 litres.............n cars
so n x 1750 = 1960 x 50
n = 98000 : 1750
n = 56
56 cars tanks will be filled
Answer:
56
Step-by-step explanation:
1750 divided by 50 to find out how much litres each car gets. =35
so 35 litres per car so divide 1960 by 35. =56
56 cars can be filled
CHECK ANSWER.
the six extra cars so 35 multiplied by 6. =210
1750+210=1960!
