Answer:
30%
Step-by-step explanation:
We know that the number of part time employees are 21. The total amount of employees is 70. We can turn these numbers into a fraction: 21/70.
If we simplify this fraction, we'll get 3/10, which is 30% as a percentage.
Answer:
Step-by-step explanation:
Let's set up a percent proportion
21/70 = x/100
Now remember:
in a:b = c:d,
a is connected to d and b is connected to c
This means:
If a is missing, (b*c)/d = a
If b is missing, (a*d)/c = b
If c is missing, (a*d)/b = c
If d is missing, (b*c)/a = d
In this case, c is missing.
(21 * 100)/70 = 2100/70 = 30
Your answer is 30%
Another way to do this is using benchmark fractions
We know that 10% of 70 is 7
So we do 10%*3 = 30% = 21
This means:
7 * 3 = 21
This also means:
21 = 30% of 70

9514 1404 393
Answer:
14.09 square units
Step-by-step explanation:
The desired area is the area of the full circle, multiplied by the fraction that is shaded. That fraction is the ratio of the sector central angle to the central angle for a whole circle: 42°/360°.
A = πr²(d/360)
A = 3.14159(6.2²)(42/360) ≈ 14.09
The area of the shaded sector is about 14.09 square units.

PLZZZ HELP MEE ILL GIVE BRAINLIEST AND 50 POINTS!!!
Answer:
The answer would be 45.
Step-by-step explanation:
5*9=45
Answer:
45
Step-by-step explanation:
First we count how many people he split it between which is 5 and we have to remember the key word here is equal so if he was left with 9 then everybody else did as well. so we multiply 5 times 9 which is 45
Kenneth Drew a scale drawing of an apartment the scale of the drawing was 2 meters:1 meter the living room is 6 m long in real life how long is the living room in drawing
Answer:
3 meters
Step-by-step explanation:
Given the scale drawing :
2m : 1m
Length of living room in real life = 6 m long
2 meter = 1 meter
Real life = scale drawing
If length = 6 meter long ;
using cross multiplication :
2 meter = 1 meter
6 meter = x
2x = 6
x = 6/2
x = 3 meter
Length of living room in drawing = 3 meters

The segments formed by the altitude to the hypotenuse of a right triangle are 8 and 10. Find the shorter leg of that triangle.
Answer: 6
Step-by-step explanation:
Since the hypothenuse is 10 and the larger leg of the triangle is given as 8, the shorter leg will be calculated as the square of the hypothenuse minus the square of the longer leg after which we find the square root of the value gotten. This will be:
Shorter leg² = 10² - 8²
Shorter leg² = 100 - 64
Shorter leg² = 36
Shorter leg = ✓36
Shorter leg = 6

- 33 - 6a = - 5(4a - 3)
could I please get some help
Answer:
can I get a better explanation and I'll help
Answer:
Step-by-step explanation:
first distribute -5(4a-3) to get -20a +15
second -33-6a=-20a+15 and add 20 to both sides to get -33+14a=15
third add 33 to both sides to get 14a=48
fourth divide 14 on both sides to get a = 3.43 (rounded to nearest hundredth)
Rachel left home for school at 7:45 one morning. She returned home at 4:05 that afternoon. How many hours and minutes was she gone? (The number of minutes in your answer must be less than 60.)
Answer:
8 hours 20 minutes
Step-by-step explanation:
Given that :
Time Rachel left for school = 7:45 a.m
Time she returned Home = 4:05 p.m
Time for which Rachael was gone :
4:05 p.m - 7:45 a.m
7:45 a.m to 3:45 p.m= 8 hours
3:45pm to 4:05 pm = 20 minutes
= 8 hours 20 minutes
Rachael was gone for 8 hours 20 minutes
A farmer sells a dozen eggs at the market for 2.00 and one of his bags of gains for 5.00 he sold 5 time as many bags of grains as he has dozens of eggs. By the end of the day he has made 243.00 worth of sales. How many bags of grain did he sell
Answer:
45 bags
Step-by-step explanation:
Cost of a dozen eggs = 2
A bag of grain = 5
Let :
dozens of eggs sold = x
Bag of grains sold = 5x
Total sales worth = 243
Quantity sold * price
2* x + 5 * 5x
2x + 25x = 243
27x = 243
x = 243 / 27
x = 9
Bags of grains sold = 5x = 9*5 = 45 bags

If the legs of a right triangle are given by x^2 - y^2 and 2xy then which expression equals the hypotenuse ? Choose all that apply
Answer:
[tex]\sqrt{\left(x^2-y^2\right)^2+\left(2xy\right)^2}[/tex]
Step-by-step explanation:
Hypotenuse of a right triangle can be found using the Pythagorean theorem which states that both legs squared and added is equal to the hypotenuse squared. In other words, if A and B are legs and C is the hypotenuse:
[tex]C=\sqrt{A^2+B^2}[/tex]
We are told that one of the legs is [tex]x^2-y^2[/tex] and the other is [tex]2xy[/tex] so we get [tex]\sqrt{\left(x^2-y^2\right)^2+\left(2xy\right)^2}[/tex] when we substitute the legs into the formula presented above.
x-27 = 7x -15
please show the work, i’ll mark brainliest
Answer:
x=-2
Step-by-step explanation:
x-27 = 7x -15
subtract x from both sides
-27=6x-15
add 15 to both sides
-12=6x
divide both sides by 6
-2=x
x=-2
Answer:
x=-2
Step-by-step explanation:
x-27=7x-15(move variable left hand side /change sign)
x-7x-27=-15
x-7x=-15+27
-6x=-15+27
-6x=12
x=-2

Lucy, Luke, and Lilly went trick-or-treating on Halloween. After they finished, they compared the amount of candy they all had. Luke had twice the amount Lilly had, and Lucy had 15 less than 3 times the amount Lilly had. If together, they had 225 candies, how many candies did Lucy have? PLEASE HELP URGENT
Hi there!
Let think talk about these clues we have right now...
Luke is x2 more than Lily.
Luce is 45 less candy than Lily since 3 times 15.
225 candys in total...
Let make a random guess...
Lily: 70
Luke: 140
Lucy: 35
Total: 245
Now we know that there must be a half candy since it’s a odd number at the end of that...
Lily: 67.5
Luke: 135
Lucy: 22.5
Total: 225
But we are asked for only Lucy...
So the answer to this problem is 22.5.

Is value of X in the equation 6x+3+4x= 1/2(9+10x)
Answer:
x = 0.3
Step-by-step explanation:
6x + 3 + 4x = 1/2 (9 + 10x)
=> 10x + 3 = 1/2 *9 + 5x
=> 5x + 3 = 9 / 2
=> 5x = 9 / 2 -3
=> 5x = (9 - 6) / 2
=> 5x = 3 / 2
=> x = 3 / 10
=> x = 0.3
Hope it helps :)
