Answer:
=4x^2−20xy+25y^2
Step-by-step explanation:
(2x−5y)^2
=(2x+−5y)(2x+−5y)
=(2x)(2x)+(2x)(−5y)+(−5y)(2x)+(−5y)(−5y)
=4x^2−10xy−10xy+25y^2
=4x^2−20xy+25y^2

A map has a scale of 1/2 inch =75 miles.If two cities are 3 3/4 inches apart,how many miles apart are they really
Answer:
3 3/4 inches = 562.5 miles
Step-by-step explanation:
Given that,
1/2 inch = 75 miles
It means,
1 inch = (75×2) miles
= 150 miles
3 3/4 inches= 15/4 inches
So,
[tex]\dfrac{15}{4}\ \text{inches}=\dfrac{15}{4}\times 150\\\\=562.5\ \text{miles}[/tex]
Hence, 3 3/4 inches is equal to 562.5 miles.

If one tenement on the Lower East Side of New York had 101 adults and 91 children, and there was an average of 8 persons in a tenement apartment, how many apartments did this tenement have?
Answer:
24 Apartments
Step-by-step explanation:
To get the total amount of people living in the apartment building, you add 101 and 92.
101+91=192 total people
You then divide this total by the amount of people staying in each apartment, which is 8.
192/8=24 apartments
This leaves you with 24 apartments, with 8 people living in each one.
Carmen needed 23 of a yard of fabric to make a shirt and a 12 yard of fabric to make a matching skirt. How much total fabric did Carmen need to buy? 1 yard of fabric 1 yard of fabric 34 yard of fabric , 3 fourths, yard of fabric 116 yards of fabric , 1 and 1 sixth, yards of fabric 56 yard of fabric
Answer:
38/3 yards
Step-by-step explanation:
Given that,
Fabric required to make a shirt = 2/3 of a yard
Fabric required to make a skirt = 12 yards
Total fabric needed,
[tex]x=\dfrac{2}{3}+12\\\\=\dfrac{38}{3}\ yards[/tex]
Hence, 38/3 yards of fabric is needed.

Find the amount and compound interest on 5000 at 6% per annum for 3 years annual
Answer:
The amount is 5,955.08
Step-by-step explanation:
Here, we want to calculate compound interest
We can find this by using the compound interest formula
A = P( 1 + r/n)^nt
A is amount
P
is the principal = 5,000
r is the interest rate = 6% = 6/100 = 0.06
n is the number of times per year in which the interest is compounded = 1
t is the number of years = 3
Substituting these values;
A = 5,000(1 + 0.06/1)^3(1)
A = 5000(1.06)^3
A = 5,955.08
In triangle XYZ right angled at Y. Find the length of the hypotenuse if the length of the other two sides is 1.6 cm and 6.3 cm.
Answer:
6.5 cm
Step-by-step explanation:
From Pythagoras theorem
C^2= a^2 + b^2
Where a, b are the sides of the triangle
C= hypotenus sides of the triangle
two sides are given as 1.6 cm and 6.3cm respectively.
C^2= 1.6^2 + 6.3^2
C^2= 2.56 + 39.69
C^2 = 42.25
C= √42.25
C=6.5 cm
Hence, the length of the hypotenuse is 6.5 cm
