Giselle works as a carpenter and as a blacksmith.
She earns $20per hour as a carpenter and $25dollar sign per hour as a blacksmith. Last week, Giselle worked both jobs for a total of 30 hours, and earned a total of $690
How long did Giselle work as a carpenter last week, and how long did she work as a blacksmith?
Answer:
she worked 12 hours as a carpenter and 18 hours as a blacksmith
Step-by-step explanation:
Let x = the number of hours for which she worked as a carpenter
Let y = be the number of hours for which she worked as a blacksmith
Total numbers of hours she worked = 30
x + y = 30 (1)
she earned a total $690. She earned $20 dollar per hour as a carpenter and $25 per hour as a blacksmith.
20 x + 25 y = 690 (2)
Equation (2) - 20 × Equation (1),
We get,
5 y = 90 ⇒ y = 18
After substituting this value in equation (1),
We get, x = 12,
Hence, She worked as a carpenter = x hours = 12 hours
And, as a blacksmith = y hours = 18 hours
Which of the following are square roots of 576
A. -24
B. 5761/2
C. 48
D. 24
E. 12
F. -5761/2
The square root of 576 is the inverse of the mathematical operation of squaring the number 24. The square root of a number implies a number whose product with itself gives the initial number. Now we will calculate the square root of 576 using various methods and a few interesting facts and problems too.
Square root of 576: 24Square of 576: 331776What Is the Square Root of 576?The square root of 576 can be written as √576 and (576)1/2
The square of 576 will be a number(a) such that a × a = 576
And 24 × 24 = 576 also -24 × -24 = 576
Therefore, +24 and -24 are the square root of 576
Is Square Root of 576 Rational or Irrational?The square root of 576 are +24 and -24.
Both numbers are integers and we know that all integers are rational numbers.
Hence, the square root of 576 is a rational number.
What is the value of X?
Answer:
x is 54˚
Step-by-step explanation:
Opposite angles are equalTherefore [tex]2x+2=3x-52[/tex]Subtract 2x from both sides[tex]2=x-52[/tex]Add 52 to both sides[tex]x=54[/tex]Answer:
x = 54°
Step-by-step explanation:
Forming the equation,
→ (2x + 2)° = (3x - 52)°
Now the value of x will be,
→ (2x + 2)° = (3x - 52)°
→ 2x - 3x = -52° - 2°
→ -x = -54°
→ [ x = 54° ]
Hence, the value of x is 54°.

There are 35,783 police officers in the city. 1/5 of them are females. There are about ___ male police officers in the city.
Answer:
7156.6 Women. 28624 Men.
Step-by-step explanation:
I used a web browser and typed "35783/5" That answers the woman part. "4/5 of 35783" Solves the male part.
There are about 4/5th = 28626 male police officers in the city.
What is a percentage?Percentage is defined as "out of 100." Similar to fractions and decimals, percentages are used in mathematics to represent subsets of a whole.
Given, there are 35,783 police officers in the city.
1/5 of them are females.
That means, 1/5th = 20%
20% are female police officers.
And 100 -20 = 80% are the male police officers.
To find the number of male police officers:
80% of 35,783
= 35783 x 80 / 100
= 28626.4
= 28626 approximated
Therefore, 4/5th male police officers in the city are 28626.

Circumference is diameter x pi so the diameter of the circle is 11.
Radius is half the diameter so the radius is 11/2 = 5.5
area of a circle is r^2 x pi
Area = 5.5^2 x pi
5.5^2 = 30.25
Area = 30.25pi

The circumference of a circle is 10π ft. What is the area, in square feet? Express your answer in terms of \piπ.
Answer:
A = 25π square feet
Step-by-step explanation:
C = 2πr
10π = 2πr
10π = 2πx
10π / 2π = 2πx / 2π
5 = x
This means 5 is the radius of the circle. We now need to find the area:
A = πr[tex]r^{2}[/tex]
A = π(5)²
A = π(25)
