Answer:

21–24 and 28 are correctly marked

25: NEI; 26: ASA or LA; 27: SSS

Step-by-step explanation:

25: At least one side is required for showing congruence. In figure 25, only angles are shown congruent, so there is not enough information.

26: Two angles and the side between them are marked congruent. These triangles can be declared congruent by ASA. Considering they are right triangles, one could also invoke LA as the appropriate theorem.

27: The unmarked sides of the two outside triangles can be shown to be congruent by virtue of the fact they are opposite congruent angles in the middle triangle. Hence all three sides can be shown congruent for those outside triangles, and the SSS postulate can be invoked.

Write 2 x 10^3 in standard notation.

Answers

Answer:

2000

Hope this helps :)

Step-by-step explanation:

Since the exponent of the scientific notation is positive, move the decimal point 3 places to the right.

The standard notation of the expression is 2 x 10³ is 2000.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

2 x 10³

Standard notation means writing an expression without any base and exponents.

Now,

10³ can be written as 1000.

So,

2 x 10³

= 2 x 1000

= 2000

Thus,

The standard notation is 2000.

Solve the equation by completing the square.
x^2 + 10x= -81

Answers

Answer:

x =-5± 2i sqrt(14)

Step-by-step explanation:

x^2 + 10x= -81

Take the coefficient of x and divide by 2

10/2 = 5

Square it

5^2 =25

add to each side

x^2 + 10x+25 = -81+25

( x+5) ^2 = -56

Take the square root of each side

sqrt(( x+5) ^2) =± sqrt(-56)

x+5 = ± sqrt(-1) sqrt(4*14)

x+5 =± i sqrt(4)sqrt(14)

x+5 =± i 2 sqrt(14)

Subtract 5 from each side

x+5-5 =-5± i 2 sqrt(14)

x =-5± 2i sqrt(14)

The function T(d)=10d + 20 gives the temperature in deegrees celcius inside the earth as a function if d, the depth in kilometers ,Find the temperature at.

Answers

Answer:

Step-by-step explanation:

The question is incomoplete. Here is the complete question.

The function T(d)=10d + 20 gives the temperature in deegrees celcius inside the earth as a function if d, the depth in kilometers ,Find the temperature at 5km, 20km and 100km

T(d)=10d + 20

T(5)=10(5) + 20

T(5)= 50+ 20

T(5) = 70

Hence the temperature is 70 when d = 5km

when d = 20km

T(20)=10(20) + 20

T(20)= 200+ 20

T(20) = 220

Hence the temperature is 220 when d = 20km

when T = 100km

T(100)=10(100) + 20

T(100)= 1000+ 20

T(100) = 1020

Hence the temperature is 1020 when d = 100km

The temperatures at 5km, 20km and 100km are; 70°C, 220°C, and 1020°C respectively.

The complete question requires that we find the temperature at 5km, 20km and 100km.

The temperature function is; T(d)=10d + 20

For 5km;

T(5)=10(5) + 20

T(5) = 70°C

For 20km;

T(20) = 10(20) + 20

T(20) = 220°C

For 100km;

T(100)=10(100) + 20

T(100) = 1020°C

A green grocer has 180 mangoes to sell. She has to arrange them in piles of 9, 10 or 12mangoes.
In which ways would she arrange the mangoes without any remaining?

Answers

Answer:

in piles of 9,10 &12

Step-by-step explanation:

this is because if you divide 180 by each number there is no remainder hence the green grocer can arrange in any way.

It is possible to arrange the total of mangoes by using 20 piles of 9 mangoes, 18 piles of 10 mangoes, or 15 piles of 12 mangoes.

What is division?

Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

The conditions for mangoes to be arranged are that the piles should have either 9, 10 or 12 mangoes and reminders are not allowed. This means you need to fit all the mangoes and no mangoes can be left.

Based on the conditions and the total number of mangoes (180 mangoes), here are the possibilities that you can determine using division:

9 mangoes piles: 180/ 9 = 20 piles (9 x 20 = 180 with no remainders)

10 mangoes piles: 180/10 = 18 piles (10 x 18 = 180 with no remainders)

12 mangoes piles: 180/12 = 15 piles (12 x 15 = 180 with no remainders)

Hence, It is possible to arrange the total of mangoes by using 20 piles of 9 mangoes, 18 piles of 10 mangoes, or 15 piles of 12 mangoes.

3 x 1/3 =

First we should understand that 3 in fraction form is 3/1.

(3 divided by 1 is three)

So we can rewrite this as;

3/1 x 1/3 =

Now just multiply across

3/1 x 1/3 = 3/3 = 1

Repeating this same logic we'll come across the following answers

10 x 1/10 = 10/10 = 1

19 x 1/19 = 19/19 = 1
