(Prove that):
2 sin 70. cos 20 = sin 90 + sin 50
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
2sinxcosy = sin(x + y) + sin(x - y) , then
with x = 70 and y = 20
2sin70cos20
= sin(70 + 20) + sin(70 - 20)
= sin90 + sin50
= right side , thus proven
If sin0= 2/5, find csc0.

1. A girl has eaten 60% of a cake .
a. What fraction of the cake has she eaten?
b. What percentage of the cake is left?
2.What percentage of 150 is 5
Answer:
#1
a. Covert % to fraction
60% = 60/100 = 3/5b. Whole is 100%, remaining is:
100% - 60% = 40%#2
5/150*100% = 3.33%Trench Warfare

If the crayon is 90 millimeters long, how
many cubic centimeters of wax is used to
make a box of 8 crayons?
Answer:
373248 cm³ of wax
Step-by-step explanation:
If the crayon is 90 millimeters long, how many cubic centimeters of wax is used to make a box of 8 crayons?
1 crayon = 90mm
8 crayons = x
Cross Multiply
x = 8 × 90mm
x = 720mm
Converting to cubic mm
= (720mm)³ = 373248000mm³
Converting to cubic centimeter
1 mm³ = 0.001 cm³
373248000 mm³ = x
Cross Multiply
373248000 × 0.001 cm³
= 373248 cm³ of wax

The price of a desktop computer decreases from $10360 to $1020. Find the percentage decrease its price
Answer: [tex]915.68\ \%[/tex]
Step-by-step explanation:
Given
Original Price=$10360
New Price=$1020
Percentage decrease in its Price is given by
[tex]\%\ \text{decrease}=\dfrac{\text{New-Original Price}}{\text{Original Price}}\times 100[/tex]
[tex]\Rightarrow \dfrac{10360-1020}{1020}\times 100=915.68\ \%[/tex]
if 15 workers complete a piece of work in 18 days in how many days will 27 workers complete the same work?
10 days is your answer
Answer:
15 workers =18 days to complete work
1 worker =18×15=270 days to complete work
27 worker=270/27=10 days to complete work
Which of the following correctly shows the length of each radius, the point where the circles intersect, and the equation of the tangent line at this point?
Answer:
Length of the radii of the circles → 4 units and 1 unit
Equation of common tangent → x = 4
Step-by-step explanation:
From the figure attached,
Length of radii of each circles are,
Radius of circle S = 4 units
Radius of circle T = 1 unit
Common point where the circles are touching → (4, 1)
Common tangent to these circles is a line perpendicular to x-axis passing through x = 4,
Equation of the tangent will be,
x = 4

What is the area of a square, rectangle, or parallelogram?
Answer:
area of a square= length ²
area of a rectangle=length*breadth
area of parallelogram=base *height
Which one is correct?
Answer:
The volume of the prism is other; 5.04 m^3
Step-by-step explanation:
Here, we want to get the volume of the prism
What we have to do here is to calculate the area of the trapezoid base and multiply by the height of the prism
The area of the base is;
A = 1/2(a + b) h
a and b are the parallel sides of the trapezoid which is 80 cm and 2 m
h is the height of the trapezoid which is 1.2 m
80 cm is same as 80/100 = 0.8 m (100 cm = 1 m)
A = 1/2( 0.8 + 2)1.2
A = 1/2 * 2.8 * 1.2 = 1.68 m^2
So we proceed to multiply this with the height of the prism which is 3 m
This will be ;
1.68 m^2 * 3 m = 5.04 m^3
I AM BEGGING YALL, PLEASE HELP ME OUT
Answer:
(2a,2b)
(-4a,b)
Step-by-step explanation:
for the first one
the x value of coordinate L is going to be twice the value of the x coordinate of k (a)
That being said the x value of L = 2a
The y value of L is going to be half the value of the y value of coordinate A ( 4b )
4b/2=2b so the y value of coordinate L is 2b
now we put the values as an ordered pair
The answer would be (2a,2b)
what is the area of a quadrilateral with vertices at (-6,6), (-1,6),(-6,10), and (-1,10)
Answer: 20
Step-by-step explanation:
The area of a quadrilateral with given vertices is 20 square units.
What is the area of the rectangle?The area of a rectangle is defined as the product of the length and width.
The area of a rectangle = L × W
Where W is the width of the rectangle and L is the length of the rectangle
We have to determine the area of a quadrilateral with vertices at (-6,6), (-1,6),(-6,10), and (-1,10).
As per the attached graph, we can see that the dimensions of the rectangle are as follows:
Length (L) = 5 units
Width (W) = 4 units
Area of the rectangle = L × W
Area of the rectangle = 5 × 4 = 20 square units

A regular 16-gon has a radius of 10 meters
Part A: determine the length of the apothem
Part B: determine the perimeter of the polygon
Answer:
9 in
Step-by-step explanation:
For an n-sided polygon, the length of the apothem is ...
a = r·cos(180°/n)
We assume your problem statement is saying the radius is 10 inches. For a hexagon, n=6 and we have ...
a = (10 in)cos(30°) ≈ 8.66 in
Rounded to the nearest inch, the apothem is 9 in.
Answer:
9
Step-by-step explanation:
cos(30)=x/10
X=8.66

where m represents the amount of minutes he spends typing. How many words has he
written after 45 minutes?
Answer:
25(45) +200= 1125+200=1325

The sum of x and 3 times y is 5. The difference of x and y is 5. Write two equations and graph to find the value of y.
Answer:
for the first one, x + 3 * y = 5
and the second equation, x - y = 5
Step-by-step explanation:
the sum of two numbers means for example the sum of 5 and 8 is 13, so as an equation that is 5 + 8 = 13
the difference is the same thing as the sum but it's subtraction.
and then times is just multiplication.
