Write an equation that relates the angles in a triangle. The measures of angles X and Y are the same, x degrees. The measure of angle Z is twice the measure of angle Y.
Answer:
4x = 180
Step-by-step explanation:
angle x = angle y so we can say both angles are 'x + x' or '2x'
angle z = twice angle y (or twice angle x because they're equal) so we can say angle z = 2x
2x + 2x = 180

9514 1404 393
Answer:
(a) 15
Step-by-step explanation:
Each of the marked angles is an exterior angle of the polygon. The sum of exterior angles is always 360°. We can use that fact to write the equation.
4x° +77° +59° +6x° +74° = 360° . . . . . an equation to find x
10x + 210 = 360 . . . . . . . . . . . . . . divide by °, collect terms
x + 21 = 36 . . . . . . . . . . . . . . . divide by 10
x = 15 . . . . . . . . . . . . . . . subtract 21

Comment on the sum of exterior angles
Imagine the figure shrunk smaller and smaller until all of the angle vertices are the same point. You can see that those angles will completely fill the angular space around that central point, so they must have a sum of 360°.
What is the total cost of 1.2 Cubic yards of soil if it sells for $24 per cubic yard?
Answer:
$28.80 I hope that helps if not I'm sorry if it's wrong
Step-by-step explanation:
we write "dollars per cubic yard" as "dollars/yd^3" so that the units "yd^3" will cancel when multiplying by "1.2 yd^3", leaving an answer in units of dollars
24 dollars / yd^3 * 1.2 yd^3 = 28.80
the cost would be $28.80

An athlete covers three consecutive miles by walking the first mile, running the second mile
and cycling the third. He runs twice as fast as he walks, and he cycles one and a half times as
ast as he runs. He takes ten minutes longer than he would do if he cycled the three miles,
How long does he take by walking, running and cycling?
ter your math answer
Answer:
Total time taken by walking, running and cycling = 22 minutes.
Step-by-step explanation:
Let the speed of walking = x
As given,
The distance of walking = 1
Now,
As [tex]Time = \frac{Distance }{Speed}[/tex]
⇒ Time traveled by walking = [tex]\frac{1}{x}[/tex]
Now,
Given that - He runs twice as fast as he walks
⇒Speed of running = 2x
Also given distance traveled by running = 1
Time traveled by running = [tex]\frac{1}{2x}[/tex]
Now,
Given that - he cycles one and a half times as fast as he runs.
⇒Speed of cycling = [tex]\frac{3}{2}[/tex] (2x) = 3x
Also given distance traveled by cycling = 1
Time traveled by cycling = [tex]\frac{1}{3x}[/tex]
Now,
Total time traveled = Time traveled by walking + running + cycling
= [tex]\frac{1}{x}[/tex] + [tex]\frac{1}{2x}[/tex] + [tex]\frac{1}{3x}[/tex]
= [tex]\frac{6+3+2}{6x} = \frac{11}{6x}[/tex]
If he cycled the three mile , then total time taken = [tex]\frac{1}{3x}[/tex] + [tex]\frac{1}{3x}[/tex] + [tex]\frac{1}{3x}[/tex] = x
Given,
He takes ten minutes longer than he would do if he cycled the three miles
⇒x + 10 = [tex]\frac{11}{6} x[/tex]
⇒[tex]x - \frac{11}{6} x = -10[/tex]
⇒[tex]-\frac{5}{6}x = -10[/tex]
⇒x = [tex]\frac{60}{5}[/tex] = 12
⇒x = 12
∴ we get
Total time traveled by walking + running + cycling = [tex]\frac{11}{6} x = \frac{11}{6} (12) = 11 (2) = 22[/tex] min
Find the shaded area:
Answer:
Step-by-step explanation:
we have a circle inscribed in a square
Area of the square
Asquare=14*14=196
Acircle=3.14*r^2
r=14/2=7
Acircle=3.14*7^2=153.94
A shaded=196-153.94=42.06
Given that f(x)=x^2-13 and g(x)=5x+1, find (fg)(-1/5)
Answer:
[tex]\displaystyle (fg)(-\frac{1}{5})=0[/tex]
Step-by-step explanation:
We are given the two functions:
[tex]f(x)=x^2-13\text{ and } g(x)=5x+1[/tex]
And we want to find:
[tex]\displaystyle (fg)(-\frac{1}{5})[/tex]
This is equivalent to:
[tex]\displaystyle =f(-\frac{1}{5})g(-\frac{1}{5})[/tex]
By substitution:
[tex]\displaystyle f(-\frac{1}{5})=(-\frac{1}{5})^2-13=\frac{1}{25}-13=-\frac{324}{25}[/tex]
And:
[tex]\displaystyle g(-\frac{1}{5})=5(-\frac{1}{5})+1=-1+1=0[/tex]
Hence:
[tex]\displaystyle =(-\frac{324}{25})(0)=0[/tex]
Our final answer is:
[tex]\displaystyle (fg)(-\frac{1}{5})=0[/tex]
A number is 4 times the sum of its digits. The units digit is two more than the tens digit. Find the number.
Answer:
24
Step-by-step explanation:
Let x = the 10's digit
Let y = the units
then
10x+y = "a number"
:
A number is 4 times the sum of its digits.
10x + y = 4(x + y)
10x + y = 4x + 4y
10x - 4x = 4y - y
6x = 3y
Simply, divide by 3
2x = y
;
The units digit is two more than the tens digit.
y = x + 2
Replace y with 2x
2x = x + 2
2x - x = 2
x = 2
then
y = 4
:
24 is the number
The two digit number is equivalent to 24.
What is expression?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that a number is 4 times the sum of its digits. The units digit is two more than the tens digit.
Let the number be {A}. Then, we can write -
A = 10x + y ......... (1)
also
A = 4(x + y) ........... (2)
The units digit is two more than the tens digit, so we can write -
y = x + 2 .............. (3)
So, we can write -
10x + y = 4(x + y)
10x + (x + 2) = 4(x + x + 2)
11x + 2 = 8x + 8
3x = 6
x = 2
So, we can write {y} as -
y = 4
Number will be -
10 x 2 + 4
n = 24
Therefore, the number will be equivalent to 24.

Answer:
2.75x+122.5
Step-by-step explanation:
Horse=x
Stork=x+70
Whale=3/4(x+70) = 0.75(x+70) = 0.75x+52.5
x+x=70+0.75x+52.5
2.75x+122.5
Answer:
2.75h + 122.5, where h = lifespan of a horse
Step-by-step explanation:
The whale's lifespan is given in terms of the stork's.
The stork's lifespan is given in terms of the horse's.
Start by assuming a variable for the lifespan of a horse.
Let h = the lifespan of horse in years.
A horse lives h years.
A stork lives 70 years longer than a horse. A stork lives h + 70 years.
A whale lives 3/4 of the lifespan of a stork. A whale lives for (3/4)(h + 70) years.
Now that you have an expression for the lifespan of each animal, the total lifespan of the three animals is the sum of the three lifespans.
total lifespan = h + h + 70 + (3/4)(h + 70
Now we simplify the right side.
total lifespan = 2h + 70 + (3/4)h + (3/4)(70)
total lifespan = 2h + 70 + 0.75h + 52.5
total lifespan = 2.75h + 122.5
Answer: 2.75h + 122.5, where h = lifespan of a horse
