Divide 192kg in the ratio of 5:3.
Answer:
120 Kg : 72 Kg
Step-by-step explanation:
Sum the parts of the ratio, 5 + 3 = 8 parts
Divide the quantity by 8 to find the value of one part of the ratio.
192 Kg ÷ 8 = 24 Kg , thus
5 parts = 5 × 24 Kg = 120 Kg
3 parts = 3 × 24 Kg = 72 Kg
192 Kg = 120Kg : 72 Kg in the ratio 5 : 3

Happy Paws charges $20.00 plus $4.50 per hour to keep a dog during the day. Woof Watchers charges $11.00 plus $5.75 per hour. Complete the equation and solve it to find for how many hours the total cost of the services is equal. Use the variable h to represent the number of hours.
The equation is: ______=______
The total cost of the services will be equal at __ hours.
Answer:
The equation is: 20 + 4.5h = 11 + 5.75h
The total cost of the services will be equal at 7.83 or 8 hours.
Step-by-step explanation:
This equation is correct because it shows that these two scenarios equal the same amount of money when there is a certain amount of hours, or "h."
Here is how we solve the equation;
20 + 4.5h = 11 + 5.75h <-----Here is the original equation.
Service A Service B
1. 20 - 20 + 4.5h = 11 - 20 + 5.75h
2.4.5h - 5.75h = -1.15h -9 + 5.75h/5.75 =
3. -1.15h/-1.15 = h 9/-1.15 = 7.83
h = 7.83 or 8 hours when rounded to the nearest hour

At a baseball game, 6 hotdogs cost $27. What is the cost of 1 hotdog? How many hotdogs can you buy for $18
Answer:
What is the cost of 1 hotdog?
Answer: $4.50
How many hotdogs can you buy for $18?
Answer: 4
Step-by-step explanation:
If $27 can buy you 6 hot dogs, to find the cost of one, we just divide.
27 divided by 6 = 4.5 ($4.50)
So 1 hotdog costs $4.50
If 1 hotdog is $4.50, and we want to know how much we can buy for $18, then we divide again.
18 divided by 4.5 = 4
So for $18, we can buy 4 hotdogs
Given that 529 × 3.8 = 2010.2
write a division with an answer of 5.29
Answer:
Step-by-step explanation:
2010.2/380= 5.29
Answer:
5.29 = 20.102 / 3.8.
Step-by-step explanation:
529 × 3.8 = 2010.2
So 529 = 2010.2 / 3.8
We need 5.29 on the left so we divide both sides by 100:
5.29 = 2010.2 / (3.8*100)
5.29 = 20.102 / 3.8
Mr. Jackson gave an exam worth 50 points.
The mean score on the exam was 38, and the standard deviation was 4.
Mr. Jackson also reported his students’ z-scores.
Corey’s z-score was –1.75. This means that Corey scored points on the exam.
Z = (score - mean)/sd
-1.75 = (x - 38)/4
Multiply both sides by 4:
-7 = x -38
Add 38 to both sides:
x = 31
He scored a 31 points on the exam
Answer:
The person above is right, and deserves brainliest.
31 Is the correct answer

Answer:
2√6
Step-by-step explanation:
Because 2 multiplied by itself is 4
4 times 6 is 24
You multiply 2 by itself is because of the square root
Square roots are the opposite of exponents
Just like how addition is the opposite of subtraction
2^2 is 4
√4=2
Since 24 has a 4 in its multiple you can simplify it into 2 and put it on the outside

3. A googol is a very large number expressed as
10100. Ms. Rogers asked her students to
determine which number is larger, a googol
or 10010. Explain how her students might use
the idea of repeated factors in order to find
the solution.
Answer:
10^100 is larger than 100^10.
Step-by-step explanation:
10^100 compared to 100^10, we have 10^100 greater. 100^50 would equal to 10^100, as 10^2=100. 10^100 would be much more than 100^10.
Hope the explanation helps!

Enter the number of rows needed and the number of seats that will be left over.
826 seats and 42 seat per row
rows
extra seats
Answer:
Assuming the covered digits are _
The sum is 826.
243 + 1_7 + _26 = 826
The objective is to determine the sum of the two unknown digits
So; we need to think about what number can we add put in 1_7 to determine the covered digit in _26
From ; 1_7 , we have the choice to pick from 0 - 9
Assuming the covered digit is 0; let's check if we are right
So; 243 + 107 + _26 = 826
350 + _26 = 826
_26 = 826 - 350
_26 = 476
So; the covered digit is in the position of 4 , but it doesn't tally together
i.e 426 is not the same as 476, which makes our assumption to be wrong.
Let consider the covered digit to be 5 for example.
So; 243 + 157 + _26 = 826
400 + _26 = 826
_26 = 826 - 400
_26 = 426
The covered digit is in the position of 4
SO;
426 = 426
Here , our assumption is right.
As such , the covered digits are 5 and 4
The sum of the two covered digits are = 5 + 4 = 9

Cliff Alsworth spent $369.75 for utilities in April, $330.90 for utilities in May, and $297.00 for utilities in June. What was Cliff's average monthly expenditure fro utilities for those three months? *
$997.65
$327.80
$332.55
$330,90
PLEASEE ITS A TEST
Answer:
$332.55
Step-by-step explanation:
In order to figure our Cliff Alsworth's average monthly spendings on utilities, we need to add the amount he's spent each month, and divide it by the amount of months he bought utilities.
369.75 + 330.90 + 287.00 = 997.65
997.65 / 3 = 332.55
Therefore, the average Cliff's average payment for utilities is $332.55 per month. Hope you ace your test! :)

HELP! ASAP! 3x - 4y = -7 and 4x + 3y = 24 solve for x and y
Answer:
x = 3
y = 4
Step-by-step explanation:
3x -4y = -7
4x + 3y = 24
write the first equation in terms of y
3x - 4y = -7
3x + 7 = 4y
3x/4 + 7/4 = y
now substitute that into the second equation
4x + 3y = 24
4x + 3(3x/4 + 7/4) = 24
4x + 2.25x + 5.25 = 24
6.25x + 5.25 = 24
6.25x = 24 - 5.25
6.25x = 18.75
x = 18.75/6.25
x = 3
last step, substitute x for 3 in the equation.
y = 3x/4 + 7/4
y = 3*3/4 + 7/4
y = 9/4 + 7/4
y = 4
Answer:

Factor the expression
70 + 95
Answer:
70+95
70=2*5*7
95=5*19
70+95=(5*2*7)+(5*19)=(5*14)+(5*19)=5*(14+19)=5*(33)
5*33=165 and 70+95=165 also
Answer:
70+95
70=2*5*7
95=5*19
70+95=(5*2*7)+(5*19)=(5*14)+(5*19)=5*(14+19)=5*(33)
5*33=165 and 70+95=165

the price of a necklace was increased by 10% to £150. what was the price before the increase
Answer:
$135
Step-by-step explanation:
10% of 150 = 15
150 - 15 = 135
Increased by 10%.
So, 150 x 0.10 = 15
The necklace was increased by £15.
The price before the increase is £150 - £15.
This amount is £135.

Answer:
No, because it fails the vertical line test ⇒ B
Step-by-step explanation:
To check if the graph represents a function or not, use the vertical line test
Vertical line test: Draw a vertical line to cuts the graph in different positions,
if the line cuts the graph at just one point in all positions, then the graph represents a functionif the line cuts the graph at more than one point in any position, then the graph does not represent a functionIn the given figure
→ Draw vertical line passes through points 2, 6, 7 to cuts the graph
∵ The vertical line at x = 2 cuts the graph at two points
∵ The vertical line at x = 6 cuts the graph at two points
∵ The vertical line at x = 7 cuts the graph at one point
→ That means the vertical line cuts the graph at more than 1 point
in some positions
∴ The graph does not represent a function because it fails the vertical
line test
