How did I get this one Wrong?

Answer:

Determine whether a number is a solution to an equation.

Substitute the number for the variable in the equation.

Simplify the expressions on both sides of the equation.

Determine whether the resulting equation is true. If it is true, the number is a solution. If it is not true, the number is not a solution.

Answer: Simple way: If the perimeter is 22, the sum of length and breadth is 11 Cm. Now the Area is 28. Factorizing 28, Possible combinations are (1,28),(2,14),(4,7).

Answer: X =24

Step-by-step explanation:

since the variable is multiplied to the fraction you have to do the opposite of multiplication to both sides.

[tex]\frac{1}{2}[/tex]÷[tex]\frac{1}{2}[/tex]=12÷[tex]\frac{1}{2}[/tex]

Do the keep change flip them simplify

x=12×2

x=24

Answer:13

Step-by-step explanation:

(y-7)²=36

Us PENDAS (Please Excuse My Dear Aunt Sally)

-7x-7=49

(y+49)=36

y=49-36

y=13

Hope this helps! Good luck!

Answer:

Step-by-step explanation:

√(y - 7)^2 = √36

y - 7 = +-6

----------------

y - 7 = 6

y = 13

-----------------

y - 7 = -6

y = 1

---------------

Therefore, y = 13 or y = 1

------------------------------------

There is no answer for y = 1, so we choose y = 13.

Answer:

75+50x=25+70x

Step-by-step explanation:

x= the number of hours

Solve:

75+50x=25+70x

    -50x        -50x

75=  25+20x

-25  -25

50=  20x

/20   /20

x=2.5 hours

Answer:

n = 10

Step-by-step explanation:
If n is next to 0.8 that means its multiplying by whatever n is and if you do 0.8 x 10 it equals to 8

Answer: n=10

Step-by-step explanation:

0.8n = 8 First step is to divide each step by 0.8 to isolate the variable

8/0.8 Next you divide 8 by 0.8 to get your answer

The answer would be 10.

To extra check your answer you can do the reverse and multiply.

0.8x10=8

So now you know for sure the answer is 10 ;-)

Answer: 12) 58.8%

13) 320%

14) 74.499%

15) 68.1%

Step-by-step explanation: To make a decimal a percentage, you need to multiply the decimal value by 100, like 0.499 as a percentage would be 49.9%, because I multiplied it by 100. Or, you could just move the decimal point 2 steps to the right.

Answer:

12

Step-by-step explanation:

17 - 10 = 7

what plus 10 equals 17?

7

so if know C is 7 we do,

7+5=?

if you count on your hands

7, 8, 9, 10, 11, 12

so in conclusion,

7+5=12

Answer:

Radius = 6

Area= 113

Step-by-step explanation:

If you want to find the radius of a circle divide its diameter by 2.

If you want to find the diameter of a circle multiply its radius by 2.

To find an area of an circle do: Pi(Radius to the power of 2)

Answer:96% increase

Step-by-step explanation:

Answer:

x = 16

a 90 degree angle is shown in the picture

90 - 58 = 32

32/2 = 16

2 x 16 = 32 + 58 equals 90 which is the full angle

Answer: The answer is 5,442,330.

Step-by-step explanation: Australia has an area of 7,617,930, and Greenland has an area of 2,175,600. 7,617,930 - 2,175,600 = 5,442,330.

Answer:

Unlikely is probably the answer.

Step-by-step explanation:

Because Likely would mean above 50%

Equally likely and unlikely would be (equally) so 50% exact.

The last option seems wrong.

So Unlikely makes the most sense

Answer:24% error

Step-by-step explanation:

subtract the estimate and the cost

93,000-75,000

=18000

divide the cost and the subtracted sum you just got

=[tex]\frac{18000}{75000}[/tex]

cross out the common factor

=[tex]\frac{6}{25}[/tex]

Multiply a number to both the numerator and denominator (easier if you multiply the number that makes the denominator 100)

[tex]\frac{6}{25} x\frac{4}{4}[/tex]

=[tex]\frac{24}{100}[/tex]

write the fraction as a percentage

=24%

Hope this helps! Good luck!

Answer:

2cm is 5km

Step-by-step explanation:

16cm is 40km

Answer: 4e+6 centimeters

Step-by-step explanation:

Multiply the length value by 100000 and you'll get your answer.

40x100000= 4e+6 (Multiplied by length value).

Answer: A - Robotics > Garden

Step-by-step explanation:

Hello! What you need to do is look at the decimals.  You can write down which clubs have smaller decimals, equal decimals, and greater decimals than other clubs.  You know that there is an equal probability for the Robotics Club and Zoology Club because 0.2 = 0.2

Robotics Club = Zoology Club

You also know that the Garden Club has the smallest percentage so:

Garden Club < Robotics Club = Zoology Club

And you also know that the technology club has the greatest percentage out of all of them so:

Garden Club < Robotics Club = Zoology Club < Technology Club

_<_ blank is less than blank, _>_ blank is more than blank, _=_ blank is equal to blank.  A way I was able to remember this is that a smaller crocodile eats a bigger crocodile.

Now use the information you know:

Garden Club < Robotics Club = Zoology Club < Technology Club to figure out the answer.

Look at the last answer.  You know the student is not more likely to join the Garden Club (0.1 or 10%) than the Robotics Club (0.2 or 20%) because the percentage of a student joining the garden club is smaller than the percentage of joining the Robotics Club.  The formula shown for that answer is correct with Garden < Robotics, but what the rest of the answer says is incorrect.

Look at the third answer.  You know that the student is not unlikely to join the Zoology Club (0.2 or 20%) than the Robotics Club (0.2 or 20%) because the probability of both is equal as shown in the formula previously made, Robotics Club = Zoology Club.

Look at the second answer.  The percentage of a student joining the robotics club (0.2 or 20%) is smaller than the percentage of a student joining the technology club (0.5 or 50%), so they are not equally likely.  The chance of a student joining the technology club is greater than the chance of a student joining the robotics club.  This answer is also not correct.

Look at the first answer.  The student is more likely to join the robotics club than the garden club because 0.2 (20%) is greater than 0.1 (10%).  The formula is also correct because Robotics > Garden, or Robotics is greater than the probability of a student joining the garden club.  The first answer is correct.

i hope it helps u :-)

Answer:

Step-by-step explanation:

Area of triangle = bh/2

A = 4*5/2

A = 10 cm sq

A of 2 triangles = 10*2 = 20 cm sq

Now, Area of 1 rectangle = lb --> 10*5 = 50 cm sq

A of 3 rectangles = 50*3 = 150 cm sq

Now, LSA = 150 cm sq. (excluding the triangles)

TSA = A of tr. + A of rec. = 20 + 150 = 170 cm sq
