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

Help me find x but in only simplified radical form
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]
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
27 is divisible by 9

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.

Answer:
Step-by-step explanation:
Solve for CF
CF = CE - FE
CF = 34 - 18 = 16
Bisectors Cut the base line they are connect to in a proportion.
40/CF = x/18
40/16 = x/18 Cross Multiply
16x = 40 * 18 Combine the right
16x = 720 Divide by 16 on both sides
16x/16 = 720/16
x = 45

Ava and her three friends went out for lunch. Their total bill was $96. If each person paid the same amount, how much would each person pay?
$______
Answer:
$24
Step-by-step explanation:
Ava + her 3 friends = 4 people total.
The bill was $96
To split this evenly among 4 people we can divide the bill by 4.
96/4 = 24
Therefore each person would pay $24.

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!

Answer:
3300 m²
Step-by-step explanation:
Area of a triangle = 1/2 x base x height
⇒ area of one triangle = 1/2 x 30 x 40 = 600 m²
Area of a square = side length x side length
⇒ area of the square = 30 x 30 = 900 m²
Surface area of square-base pyramid = area of 4 triangles + area of square
⇒ SA = 4 × 600 + 900 = 2400 + 900 = 3300 m²

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.
