What is the remainder of 42, 325 divided by 47 ?
A : 25
B : 26
C : 35
D : 36
will give brainliest! pleaseee
Answer:
remainder 25
Step-by-step explanation:
if 42,325 is divided by 47the result is 25,
firstly divide 42,325 by 47, you will see that it can only divide 42,325 which is 900 without any remainder,then the 900 is the whole number and 25 is remaining from the subtraction of 42,325-42,300=25 ,and 25 has to be divided by 47 but it is not up to 47,then we have it as a remainder,
so 25 is the remainder

Which of these is a factor in this expression?
5z4 – 3+8 (y + 4)
O A. (y + 4)
OB. 8 (73 + 4)
O C. 524 – 3
OD. -3+8 (+ 4)
Answer:
A. (y + 4)
Step-by-step explanation:
A factor means that it can be multiplied to a number or an expression to form exactly another expression or another number which are not fractions or decimals, they have no remainder. Looking for a factor, you need to see what is being multiplied. The brackets indicates what is being multiplied. Therefore (y + 4) is the factor since it is being multiplied to the number. Even the number
'524 - 3 + 8' is a factor
Further example to familiarize yourself can be
2 x 3 = 6
2 and 3 are both factors of 6. They are both being multiplied to form 6.
Hope this helps.

Together, two pipes can fill a tank in 3 hours.
One pipe alone can fill the tank in 5 hours.
How long does it take for the other pipe to
fill the tank alone?
Answer: 7.5 (h)
Step-by-step explanation:
Let say
a the outflow of the first pipe
b the outflow of the second pipe
T the volume of the tank.
x the time for filling with the second pipe
two pipes can fill a tank in 3 hours: a*3+b*3=T
One pipe alone can fill the tank in 5 hours : a*5=T
3*b=T -3a ==> 3b= 5a*3a=2a
b=2a/3
b*x=T ==> 2/3*a*x=T ==> 2/3*T/5*x=T ==> 2/15*x=1
x=15/2 = 7.5 (hours)

Answer:
Step-by-step explanation:
2∠0PQ = 36
∠OPQ = 36/2 = 18°
Join OQ,
ΔOPQ is an isosceles triangle as OP = OQ = radius
∠OQP = ∠OPQ {Angles opposite to equal sides are equal}
∠OQP = 18°
∠ORQ = 36
ΔORQ is an isosceles triangle as OR = OQ = radius
∠OQR = ∠ORQ {Angles opposite to equal sides are equal}
∠OQR = 36°
∠PQR = ∠PQO + ∠OQR
= 18 + 36
∠PQR = 54°
∠POR = 2*∠PQR {Central angle theorem}
= 2 * 54
∠POR = 108°
∠PQR + ∠PSR = 180 {Opposite angles of cyclic quadrilateral}
54 + ∠ PSR = 180
∠PSR = 180 - 54
∠PSR = 126°
∠PSR + ∠RST = 180 {linear pair}
126 + ∠RST = 180
∠RST = 180 - 126
∠RST = 54°

y=15/4-7x
Problem 13:
6x=31-5y
x=31-5y/6
Answer:
13) Ans;
[tex]6x + 5y = 31 \\ 6x = 31 - 5y \\ \\ x = \frac{31 - 5y}{6} \\ \\ x = \frac{31}{6} - \frac{5y}{6} [/tex]

A 2-liter bottle of juice costs $2.80. A box containing six 12-liter bottles sells for $3.90. Which option has a higher cost per liter? What is that cost?
Answer:The first option has a higher cost per liter and the required cost is $1.40 per liter.
Step-by-step explanation:
Step-by-step explanation: Given that a 2 liter bottle of juice cost $2.80. A box containing six 12 liter bottle sells for $3.90.
We are to select the option that has a higher cost per liter.
We will be using the UNITARY method to solve the given problem.
Option (1) :
The cost of 2 liter bottle of juice = $2.80.
So, the cost of 1 liter bottle of juice will be
Option (2) :
The cost of six 12 liters bottle of juice = $3.90.
So, the cost of 1 liter bottle of juice will be
Since 0.05>1.40, so the option of 2 liter bottle costing $2.80 has a higher cost per liter.
And, the required cost is $1.40 per liter.

Lois makes customised tee-shirts. She advertises and receives orders through her own website. She buys blank tee-shirts for $1 each and $1 of fabric paint is used to produce the bespoke designs. She pays herself $6 per hour for her time to create the designs and package the teeshirts. In addition she makes a profit of 20% of the selling price. For how much will she sell a tee-shirt, if the artwork and packaging takes one and a half hours to complete?
Lois will sell her tee-shirt for $13.20
The percentage profit = [tex]\frac{profit}{cost price}[/tex] × 100
Profit = Selling price - cost price
Cost price is the total amount expended in making the tee-shirts
cost price includes cost of buying blank shirt , cost of fabric paint and amount Lois pay herself
cost of buying blank shirt = $1
cost of fabric paint = $1
amount Lois pay herself = [tex]1\frac{1}{2}[/tex] x $6
[tex]\frac{3}{2}[/tex] x $6 = $9
Total cost price = $1 + $1 + $9 = $11
0.2 = [tex]\frac{profit}{11}[/tex]
profit = 11 x 0.2 = $2.2
$2.20 = selling price - $11
selling price = $11 + 2.20 = $13.20
