SOMEONE HELP, I HAVENT BEEN PAYING ATTENTION TO CLASS
Answer:
A=4cm
ok to do this we do the formula
A=PiR^2
A=3.14*4^2
A=3.14*16
A=50.24
and the area of circle B is 4 times the area of a so
50.24*4=200.96
200.96=3.14*X^2
Since r is on the right side of the equation, switch the sides so it is on the left side of the equation. 3.14 ⋅ r 2 = 200.96 Divide each term by 3.14 and simplify.
r 2 = 64
r=8
CIRLCE A=50.24
CIRLCE B=8
Solve this equation 2/4x- 1/5x=x-1
Answer:
x = -10/7
Step-by-step explanation:
Assume that you meant (2/4)x - (1/5)x = x - 1. The parentheses are important for clarity.
Start the solution by combining the x terms. Note that the LCD here is 20, and that the problem thus becomes
(10/20)x - (4/20)x = x - 1
This simplifies to (6/20)x = x - 1, or
(3/10)x = x - 1
Note that 'x' = '10/10x', and so (3/10)x = (10/10)x - 1, or
-1 = (7/10)x
Multiplying both sides by 10, we get 7x = -10, and therefore x = -10/7
What is sin 45°? O A. 1/2 12 1 OB. NI O C. 1 O D. O E. 1 3 O F. 13 ap.ex
1/√2
Step-by-step explanation:
Imagine a right-angled triangle, for e.g. Triangle ABC,
Where
B = 90°
Remember your Toa Cah Soh.
sin 45° = opposite / hypotenuse
If theta = 45°
Angles A and C = 45° (Sum of angles in a triangle equal = 180°)
Since theta are the same, we can also deduce that the length AB and BC are the same.
Take for example AB = BC = 1 = opposite
By the Pythagorean theorem,
AB² + BC² = AC²
1² + 1² = AC²
2 = AC²
AC = √2 = hypotenuse
Therefore:
sin 45° = opposite / hypotenuse
sin 45° = 1/√2
What’s the length of HI?
Answer:
3
Step-by-step explanation:
HJ = 9 and IJ = 6.
HJ = HI + IJ
9 = HI + 6
HI = 9-6=3
Express sin Q as a fraction in simplest terms.
Answer:
[tex]hypotenuse = \sqrt{ {27}^{2} + {36}^{2} } \\ = \sqrt{2025} = 45 \\ \sin \: Q = \frac{opposite}{hypotenuse} \\ \sin \: Q = \frac{36}{45} \\ \sin \: Q = \frac{4}{5} [/tex]

A 301.44
B150.72
C56.24
D8.37
Answer:
A.
Step-by-step explanation:
The formula for finding the volume of a cylinder is = Base x height.
So the base is 50.24 inches
The height is 6 inches
Making it 50.24 x 6 = 301.44 inches².
Johnny is collecting pennies. He begins the month of February with 34 pennies in his collection. He collects 13 pennies in the first week of February, 9 in the second week, 6 in the third week, and 7 in the fourth week. How many pennies does Johnny have at the end of February?
Answer:
69 pennies
Step-by-step explanation:
Below is the given data:
Pennies at the starting of February = 34
Pennies in 1st week of February = 13
Pennies in 2nd week of February = 9
Pennies in 3rd week of February = 6
Pennies in 4th week of February = 7
To find the number of pennies at the end of February just add all the pennies.
At the end of February, the number of pennies = 34 + 13 + 9 + 7 +6 = 69 pennies

x is 70
Step-by-step explanation:
I've tried to solve it as easy as I could. if you still need help you can ask
Answer:
x = 50°
Step-by-step explanation:
The sum of exterior angles in any polygon is 360°. X is an exterior angle, so to find x, we must form the equation x+70+90+60+90=360
We can simplify it and solve the equation as follows:
x+310=360
x=50

Jasmine needs to correct a quality control issue with her company's product. Clear standards for quality exist, and she has measured present performance against these standards. Jasmine has discovered a deviation where the company is not meeting the standard and is now investigating the causes of those deviations. What function of management is Jasmine involved in
Answer: controlling
Step-by-step explanation:
Controlling is the management function which helps in seeking planned results from the workers and clients in an organization. This is vital as it helps in measuring progress towards the achievement of organizational goals. It also helps in bringing deviations, and then indicate an appropriate corrective action.
Therefore, based on the information given, the function of management that Jasmine is involved in us controlling function.

Tabi likes elimination the best so she decides that she will solve them all with elimination. Her teacher said one of the systems is set up for elimination. Which system do you think the teacher is referring to? Explain your reasoning
Answer:
System 1
Step-by-step explanation:
Tbe elemination method of solving system of equation works on such a way that :
Given two set of equation (1) and (11) having two unknowns, the Coefficient are of one of the unknowns, either x or y is the same such that applying the addition or subtraction operation of the two equations eliminates one of the unknown variables leaving us with only one unknown variable to solve, and then using this solution to solve for the other variable.
In the question given. The variable setup for elimination is the x variable such that by using the addition operation, variable x is eliminated.
Using a sixteen-sided number cube, what is the probability that you will roll an odd number or an even prime number? Round to three decimals.
a. 0.813
b. 0.313
c. 0.563
d. 0.156
Answer:
0.563
Step-by-step explanation:
Probability is defined by the amount of desirable outcomes over the total number of outcomes. When rolling a 16 sided number cube, there are 16 different numbers you can roll, which means 16 total outcomes. There are 8 odd numbers that you can possibly roll:
1, 3, 5, 7, 9, 11, 13, 15
Now, an even prime numbers are included in the desirable outcomes too. The only even prime number is 2. Since the odd numbers and even prime numbers do not have common term, to get the total desirable outcomes, you can add the two: 8 + 1 = 9. From the basic probability formula you can say the probability is 9/16 or 0.5625. This rounds to 0.563.
If you were too lazy to calculate, you can realize that 0.563 is the only reasonable answer because it is close to 1/2 or 0.5 and half the numbers are odd and only one is even and prime which makes the amount a bit over 1/2.

Answer:
Rs. 3,14,532
Step-by-step explanation:
When 10 is added to twice a number and the result doubled, the final result is 32.
Find the number
Answer:
The number is 11
Step-by-step explanation:
From 32 you have to minus 10 because 10 is added for the number which we can say for example is X . from 32 when you minus 10 it is 22 . To find X it says that when 10 is added to twice the number , twice the number is 22 . 22 is twice the amount of X , so to find X we have to half 22 which is 11

Answer: $1,000
Step-by-step explanation:
We are trying to find 5% of 20,000. Always remember that the "of" can be changed to a multiplication, and that "percent" means per hundred. So you will write (5/100) x 20,000 = 0.05 x 20,000 = $1,000.00
