A quality-control inspector examined 260 calculators and found 11 of them to be defective. At this rate, how many defective calculators will be in a batch of 5,200 calculators?

Step-by-step explanation:

error is in ∆ABC =~ ∆RST

because it is,

∆ABC =~ ∆RTS or ∆STR

because,

AB = RT

BC = TS

CA = SR

hope this answer helps you dear! take care.

The error is in labelling the triangles.

A triangle is a polygon with three sides having three vertices. The angle formed inside the triangle is equal to 180 degrees.

Given are two ABC and RST

Since, Δ ABC ≅ Δ RST

That gives,

AB = RS

BC = TS

CA = RT

In figure,

AC has been equated to RS, which is wrong or incorrect because the corresponding side of AC is RT

The correct labelling will be

AB = RS = 5

BC = TS = 5

CA = RT = 5.5

Hence, The error is in labelling the triangles.

Answer:

Step-by-step explanation:

Convert the exponential equation to a logarithmic equation using the logarithm base  

( 5 )  of the left side  ( 25 )  equals the exponent  ( 2 ) .   log 5 ( 25 ) = 2

Use the definition of a logarithm,  

log b ( x ) = y  ⟹  b y = x , to convert from the logarithmic form to the exponential form.

Answer:

Let Jiri's age be as 'x'

Therefore, Pamela's would be 2x

Since the addition of both is 72, the equation formed would be..

2x+ x =72

3x =72

x= 72÷3

x = 24 years.

Therefore, Jiri's age is 24 and Pamela's is twice of Jiri ie 48 years.

Answer:

51,000

Step-by-step explanation:

50,000

20% raise is

50,000 + 50,000 * 20/100

= 50,000 + 10,000

= 60,000

15% tax is

60,000 * 15/100

= 9000

so total money is 60000 - 9000

= 51000
