Step-by-step explanation:
Find the 30% decrease:
21*0.3 = 6.3
Find new price:
21-6.3 = 14.7
Answer:
$14.7
Step-by-step explanation:
First, we need to convert the percentage to a decimal. 30% = .30
Now we multiply the price times the decimal, 21 x .30 = 6.3
We subtract this amount from the previous cost. 21 - 6.3= $14.7

A pole that is 3.2m tall casts a shadow that is 1.66m long. at the same time a nearby tower cast a shadow that is 39.5 m long. how tall is the tower?
Answer:
76.14 m
Step-by-step explanation:
create a proportion of height/shadow equals height/shadow
3.2/1.66 = h/39.5
cross-multiply:
1.66h = 39.5(3.2)
1.66h = 126.4
h = 76.14

“Find the trig function and simplify if you can”
Answer:
[tex]\sqrt{10}[/tex]/10
Step-by-step explanation:
cos is adjacent side/hypotenuse
you need to find the hypotenuse
Let h = length of hypotenuse
[tex]6^{2} + 18^{2} = h^{2}[/tex]
[tex]h^{2}[/tex] = 36 + 324 = 360
h = [tex]\sqrt{360}[/tex] = 6[tex]\sqrt{10}[/tex]
cos (theta) = 6/6[tex]\sqrt{10}[/tex] = 1/[tex]\sqrt{10}[/tex] = [tex]\sqrt{10}[/tex]/10

A zip line starts on a platform that is 40 meters above the ground. The anchor for the zip line is 198 horizontal meters from the base of the platform. How long is the zip line? help grifjin
Answer:
Solution given:
perpendicular distance =height [p]=40m
base or horizontal distance [b]=198m
Hypotenuse or zip line [h]=?
Now
By using Pythagoras law
h²=p²+b²
h²=40²+198²
h=√40804
h=202m
So the Zip line is 202m long.

the diagram shows a parallelogram. work out the value of x
Answer:
x = 39
Step-by-step explanation:
The opposite angles of a parallelogram are congruent, so
3x - 15 = 2x + 24 ( subtract 2x from both sides )
x - 15 = 24 ( add 15 to both sides )
x = 39
The value of x from the parallelogram is given by the equation x = 39°
What is a Parallelogram?A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure
The four types are parallelograms, squares, rectangles, and rhombuses
Properties of Parallelogram
Opposite sides are parallel
Opposite sides are congruent
Opposite angles are congruent.
Same-Side interior angles (consecutive angles) are supplementary
Each diagonal of a parallelogram separates it into two congruent triangles
The diagonals of a parallelogram bisect each other
Given data ,
Let the parallelogram be represented as ABCD
Now , the total internal angle of a parallelogram is 360°
Now , the equation will be
∠A + ∠B + ∠C + ∠D = 360°
Substituting the values in the equation , we get
3x - 15 + 2x + 2x + 2x + 24 = 360° be equation (1)
On simplifying the equation , we get
9x + 9 = 360
Subtracting 9 on both sides of the equation , we get
9x = 351
Divide by 9 on both sides of the equation , we get
x = 39°
Therefore , the value of x is 39°
Hence , the equation is x = 39°

solve for x in the equation
Answer:
x = 12
Step-by-step explanation:
This is a supplementary angle so the right side is equal to 90°. This means the other side must also equal 90°
So subtract 20° from 90° and you get 70°
Next you can just (6(12)-2) or continuously substitute until you get the right answer.
if a cheetah jumps 7 meters how many centimeters did the animal jump
help pls and explain
=============================================
Explanation:
To convert from meters to cm, you multiply by 100. This is because there are 100 cm in one meter.
You can write it out like this
1 m = 100 cm
7*(1 m) = 7*(100 cm) .... multiplying both sides by 7
7 m = 700 cm
Note: 7 meters = 22.97 feet approximately
If a cheetah jumps 7 meters then the animal will jump 700 centimeters.
How do you convert meters into centimeters?One meter is equal to 100 times centimeters. To convert meters into centimeters multiply the factor by 100 centimeters.
To convert meters into cm, we will multiply by 100. This is because there is 100 cm in one meter.
We know that,
1 m = 100 cm
For 7 m
= 7 x (100 cm)
= 700 cm
