870 g of brass contains 40 percent zinic and the rest is copper.find the mass of zinic and copper in the alloy
Answers
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.

Mr.Hershamn has purchased a farm that is in the shape of a rectangle. The dimensions of the piece of land are 2.6km by 4.37km. How many square kilometers did he buy,and how many hectares did he purchase
Answers
Answer:
11.362 sq km
1136.2 hectares
Step-by-step explanation:
Given that:
The farm is in the shape of a rectangle.
Dimensions of the rectangular shaped land = 2.6 km by 4.37 km
To find:
Area of land bought in square km and in hectares.
Solution:
First of all, let us have a look at the formula for area of a rectangular shape figure.
[tex]Area = Length \times Width[/tex]
Here,
Length = 2.6 km
Width = 4.37 km
So, Area = [tex]2.6 \times 4.37 = 11.362\ sq\ km[/tex]
To convert square kilometers to hectares, we can use the following conversion formula:
1 sq km = 100 hectares
11.362 km = 100 [tex]\times[/tex] 11.362 = 1136.2 hectares

the perimeter of a rectangle is (8x + 7y) feet, give two possible dimensions of the rectangle
please help ??
Answers
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.

Find the component form of the resultant vector.
f = (10,5)
v = (-3,-10)
Find: -f +v
Answers
Answer:
(-f+v) = -13i-15j
Step-by-step explanation:
Given that,
Vector f = (10,5) = 10i+5j
Vector v = (-3,-10) = -3i-10j
We need to find (-f+v).
Let x = (-f+v)
Plug all the values,
x = [-(10i+5j) + -3i-10j]
= (-10i-3i)+(-5j-10j)
= -13i-15j
Hence, (-f+v) = -13i-15j

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.
Answers
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

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
Answers
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
