870 g of brass contains 40 percent zinic and the rest is copper.find the mass of zinic and copper in the alloy
Step-by-step explanation:
Mass of Zinc = 870g * (40/100) = 348g.
Mass of Copper = 870g - 348g = 522g.
Mass of zinc = 40/100*870 = 348
Mass of Copper = 60/100*870 = 522
Therefore, the mass of zinic in the alloy is 348 and the mass of copper in the alloy is 522.

The family built a house that has a length and width in a ratio of 5: 4, what is the length and width of the house if the total area of two identical floors is 160m2
I hope it will help u , please Brain -list the question
Step-by-step explanation:As given that
L:W=5:4
L/W=5/4
L=(5/4)W
hence we also know that
Area of rectangle= L*W
As given A=160m2
putt the value of A and L=(5/4)W in above equation ,
hence 160 = (5/4)W * W
W^2 = 160*4/5
W^2 = 32*4
W^2=128
taking square root
W= +_ 11.3
but length can't be negative so we take positive value of W
W=11.3 m
Now for L putt in above equation,
L=5/4 * 11.3 = 14.12 m
If A = 50 degrees, B = 62 degrees, and a = 4, find b.
Round to the nearest tenth.
=================================================
Work Shown:
Use the law of sines
b/sin(B) = a/sin(A)
b/sin(62) = 4/sin(50)
b = sin(62)*4/sin(50)
b = 4.61042489526572
b = 4.6
Make sure your calculator is in degree mode.

the perimeter of a rectangle is (8x + 7y) feet, give two possible dimensions of the rectangle
please help ??
Answer:
Two possible dimensions of the rectangle are 4x and 7/2 y.
Step-by-step explanation:
The Perimeter of a Rectangle
It's given the perimeter of a rectangle is
P = 8x + 7y
The formula to calculate the perimeter of a rectangle of dimensions L and W is:
P = 2W + 2L
Equating term by term, we can guess two possible dimensions of the rectangle:
2W = 8x
Dividing by 2:
W = 4x
And also:
2L = 7y
Dividing by 2:
L = 7/2 y
Thus, two possible dimensions of the rectangle are 4x and 7/2 y.
based on the information in the table wich of these key features is incorrect
A grocery store sells tangerines in 25kg bags. A customer bought 4 kg of tangerines for a school party. How many bags did he buy? (2 points) A. Write a multiplication equation and division equation to represent the situation.
Answer:
x = 4/25
Step-by-step explanation
Amount of tangerines in bags sold = 25kg
If a customer bought 4kg of tangerines, the number of bags he bought is expressed as x;
4 kg = x bags
25 kg = 1 bag
Cross multiply
25 x = 4 * 1
25x = 4
Divide both sides by 25
25x/25 = 4/25
x = 4/25
Hence the required equation is x = 4/25
Answer:
So if you are in middle school like me, they are asking for an equation answer, and that equation is 4 divided by 2/5 = _ and _ x 2/5 = 4

3(1−9a)+22a=2(2a−9)−15
i need a step by step explanation
Step-by-step explanation:
3(1-9a)+22a=2(2a-9)-15
3-27a+22a=4a-18-15
-27a+22a-4a=-18-15-3
-a=-36
a=36
Answer:
A= 4
Step-by-step explanation:
3(1-9a)+22a=2(2a-9)-15
3-27a+22a=2(2a-9)-15
3-5a=2(2a-9)-15
3-5a=4a-33
3-5a-3=4a-33-3
-5a=4a-36
-5a-4a=4a-36-4a
-9a=-36
-9a/-9 = -36/-9
A=4

Three guys rent a hotel room for the night. When they get to the hotel they pay the $30 fee, then go up to their room. Soon the bellhop brings up their bags and gives the lawyers back $5 because the hotel was having a special discount that weekend. So the three lawyers decide to each keep one of the $5 dollars and to give the bellhop a $2 tip. However, when they sat down to tally up their expenses for the weekend they could not explain the following details:
Each one of them had originally paid $10 (towards the initial $30), then each got back $1 which meant that they each paid $9. Then they gave the bellhop a $2 tip. HOWEVER, 3 • $9 + $2 = $29.
The guys couldn't figure out what happened to the other dollar. After all, the three paid out $30 but could only account for $29.
Can you determine what happened?
Answer:
I didnt understand but lets just say the bellhop took ot
If Clare earns $75 the next week from delivering newspapers and deposits it in her account, what will her account balance be then? her account balance is $-50 to start out with
Answer:
25
Step-by-step explanation:

The Clare account balance after the deposit of $75 will be $25.
What is subtraction?To subtract in mathematics is to take something away from a group or a number of objects.
In other meaning, subtraction is a mathematical operation such that two values are going to subtract and give a resultant value.
As per the given,
The account balance initial = -$50
The amount of deposition = $75
Total amount = -$50 + $75
⇒ $25
Hence"The Clare account balance after the deposit of $75 will be $25".
