Answer:
CL=9
Step-by-step explanation:
angle B=30
so angle A=60
Since AL bisects angle A, angles LAB and CAL both =30
Then triangle ALB is isosceles since angles B and LAB are equal
Therefore segment AL=segment LB
then
sin angle CAL (30)=CL/LB
.5=CL/18
CL=9
FIND THE VOLUME OF THIS PLEASE!!!!
Answer:
60
Step-by-step explanation:
length * width * heigth so 4*3*5=60cm^3
Answer:

Graph y = x + 4.
The picture shows the graph
Answer:
Following are the solution to the given question:
Step-by-step explanation:
Please find the attached file of the graph:
In the question by adding through 4, Y's value is the amount you now have that I choose 3 as x value. 3+4=7 So
If x=3, y=7, Then chose the value x that is 4 and −6 When x=-10, y=-6
by putting the ruler value through each of them and draw a line, that extend the line to the graphical edge field.

Answer:
a). 6ab. b) C6 c)10y7 d)12g4h5the surface of a cube is 13 1/2 cm squared. how long is one side of the cube
A cube has 6 sides. Divide the surface area by 6 to get the area of one side:
13 1/2 /6 = 2 1/4
The area of one side is S^2
To fins the length of the sides find the square root of the area:
Side = sqrt(2 1/4)
Side = 1 1/2 cm.
Mr. Peters made 5000 milliliters of fruit punch for a luncheon how many liters of fruit punch did she make
Answer: She made 5 liters of punch for a lunch.
Step-by-step explanation:
We know that,
1 liter = 1000 milliliters
Then, 1 milliliter = [tex]\dfrac{1}{1000}[/tex] liters
We are given that,
Mr. Peters made 5000 milliliters of fruit punch for a lunch.
i.e. in liters, it will be [tex]\dfrac{5000}{1000}[/tex] liters.
i.e. in liters, it will be 5 liters.
i.e. She made 5 liters of fruit punch for a lunch.
Hence, she made 5 liters of fruit punch for a lunch.

Given:
Subtract [tex]-7x^2+1[/tex] from [tex]-2x^2-4x[/tex].
To find:
The result after subtraction.
Solution:
Subtract [tex]-7x^2+1[/tex] from [tex]-2x^2-4x[/tex]. It canbe written as
[tex]-2x^2-4x-(-7x^2+1)[/tex]
Using distributive property, we get
[tex]=-2x^2-4x-(-7x^2)-(1)[/tex]
[tex]=-2x^2-4x+7x^2-1[/tex]
On combining like terms, we get
[tex]=(7x^2-2x^2)-4x-1[/tex]
[tex]=5x^2-4x-1[/tex]
Therefore, the required expression after subtraction is [tex]5x^2-4x-1[/tex].
Audrey has $111 to spend on a tennis racket and lessons. The racket costs $55 and the lessons cost $14 per hour. Define a variable. Then write and solve an equation to find how many hours of lessons she can afford ?
( pls answer this )
Answer:
Audrey can afford 4 hours of lesson.
Step-by-step explanation:
Given that:
Amount Audrey has to spend = $111
Cost of racket = $55
Cost per lesson = $14
Let,
y be the total cost
x be the number of hours
According to given statement;
y = 14x + 55
111 = 14x + 55
111 - 55 = 14x
14x = 56
Dividing both sides by 14
[tex]\frac{14x}{14}=\frac{56}{14}\\x=4[/tex]
Hence,
Audrey can afford 4 hours of lesson.
Compare the lengths of the segments. Rope C is _______ times as long as rope A. Write a multiplication equation
Answer:
Twice ; c = 2a ; a = c/2
Step-by-step explanation:
Since the drawing area has been gridded, accurate calculation could easily be performed ;
Rope A occupies 5 boxes
Rope C occupies 10 boxes
Hence,
10 boxes for C / 5 boxes for A
Therefore,
Rope C is Twice the length of Rope A.
If length of Rope A = a ; length of Rope C = c
Then, a multiplication equation for the length of Rope C equals ; c = 2a
Division equation :
a = c/ 2

factor the expression: 7x(x^2-1)-3(x^2-1)
Answer:
x = 1
Step-by-step explanation:
The factors of the given expression is as follows:
[tex]7x(x^2-1) -3(x^2-1)\\\\7x^3 - 7x - 3x^2 +3\\\\7x^3 - 3x^2 -7x + 3[/tex]
If we considered x = 1
So
7 - 3 -7 + 3 = 0
0 = 0
Hence, the factor would be x = 1

Graph the line whose y-intercept is - 4 and whose x-intercept is -2.
Answer:
Answer is (-2,-4). Place this on a line graph.
Step-by-step explanation:
The below straight line represents the graph of the equation with a y-intercept of -4 and an x-intercept of -2.
To graph the line with a y-intercept of -4 and an x-intercept of -2, we can plot these two points and then draw a straight line passing through them.
The y-intercept is the point (0, -4), which means the line intersects the y-axis at -4.
The x-intercept is the point (-2, 0), which means the line intersects the x-axis at -2.
Plotting these two points on a coordinate plane, we get below shown a straight line.
This straight line represents the graph of the equation with a y-intercept of -4 and an x-intercept of -2.

Calculate ZQRP
12 cm
Р
R
18 cm
Answer:
<QRP = 48.2°
Step-by-step explanation:
Given:
PR = 18 cm
QR = 12 cm
Required:
<QRP = angle R
Solution:
Reference angle = <R (<QRP)
Adjacent side length = 12 cm
Hypotenuse = 18 cm
Thus:
Cos (R) = 12/18
cos (R) = 0.6667
[tex] R = Cos^{-1}(0.6667) [/tex]
[tex] R = 48.1871227 [/tex]
