Answer:

The area of the model on the right is 80 sq cm

Step-by-step explanation:

Since the scale for the model on the left is 1 cm = 5 ft, and the scale for the model on the right is 1 cm = 2.5 ft, the area of the model on the right is 22, or 4, times larger than the area of the model on the left.

Multiply the area of the model on the left by 4 to find the area of the model on the right.

20 sq cm × 4 = 80 sq cm

Answer:

x + 37 = 90

Step-by-step explanation:

Since complementary angles add up to 90 degrees, we would need to add 37 and x to equal 90 degrees. Therefore, x + 37 equals 90 degrees. As for solving, subtract 37 from both sides and you are left with x = 53.

Answer:

Below in bold.

Step-by-step explanation:

5x - 3y = 1

3x- y = 5                    Multiply this equation by -3:

-9x + 3y = -15            Now add this equation to the first equation:

-4x = -14

x = -14/-4 = 3.5.

Now substitute for x in equation 1:

5(3.5) - 3y = 1

-3y = 1 - 17.5

-3y = -16.5

y = 5.5.

Answer:

44

Step-by-step explanation:

2 x 2 = 4 which is the inner area without carpet.

12 x 4= 48 is the total area including the inner area

48-4=44 which is the area with carpet

answer:

-2x + 9 or -2 which is what the question asks

step-by-step explanation:

5x + 9 + (-7x) = __x + 9

-2x + 9

Answer:1

Step-by-step explanation:

Find the value of each number in a logarithm table:

log 0.3452 = -0.4619

log98.56 = 1.9937

log0.06541 = -1.1844

log451 = 2.6542

Add the top two together, then the bottom two:

Top two: -0.4619 + 1.9937 = 1.5318

Bottom two: -1.1844 + 2.6542 = 1.4698

Now subtract the sum of the bottom from the sum of the top:

1.5318 - 1.4698 = 0.062

Now find the antilog:

10^(0.062)

Answer = 1.1535

Answer:

When c and a are positive or both are negative

Step-by-step explanation:

negative times negative equals positive so if a was negative and c was negative -a*-c= ac

Of course positive times positive equals negative so if a and c were positive we could do

a*c= ac

Hope I could help !

Step-by-step explanation:

Answer:

c)  ([tex](6-\sqrt{12} )(6+\sqrt{12} ) = 24[/tex]

d)    ([tex](3+\sqrt{8} )(3-\sqrt{8} ) = 1[/tex]

Step-by-step explanation:

Step(i):-

Given that the binomial expression

          ([tex](6-\sqrt{12} )(6+\sqrt{12} )[/tex]

Multiply

        ( 36 + 6√12 -6√12 -(√12)²)

    =  ( 36 -12)

   =  24

c)  ([tex](6-\sqrt{12} )(6+\sqrt{12} ) = 24[/tex]

Step(ii):-  

Given that the binomial expression

          ([tex](3+\sqrt{8} )(3-\sqrt{8} )[/tex]

Multiply

 =  9 - 3√8 + 3√8 -(√8)²

=   9 - 8

= 1

d)    ([tex](3+\sqrt{8} )(3-\sqrt{8} ) = 1[/tex]

Answer:

Below.

Step-by-step explanation:

15y + 12x = 18

5y + 4x = 6

The  second equations is the first times 3 so they are basically the same.

Infinite Solutions.

2x+ 3y= 12

-6y= 4x-24          Rearranging the second equation:

-4x - 6y = -24      Multiplying the first equation by 2:

4x + 6y = 24      

- we see that the last equation is -1 * previous equation.

So there are infinite solutions.

Answer:

42cm square

Step-by-step explanation:

Frist find the area of the square. 14*14

Then find the Area of the circle.- (radius) one side of the square is the diameter so, diameter divided by 2 - 14/2=7

After that subtract the area of circle from the area of the square.

Answer:

first we find the area of the square.

area of square=side²

area of square =14²

area of square=196cm²

area of circle=pi×radius²

radius=14/2=7

area of circle=22/7×(7)²

area of circle =22/7×49

area of circle =154cm²

area of shaded region=area of square - area of circle

area of shaded= 196cm²-154cm²

area of shaded=42cm²

Step-by-step explanation:

g(0)= 1

g(5)= 1-3/20 = 17/20

-5.g(4)-1 =-5. (13/16) -1 = -65/16 -1= (-65-16)/16= -81/16

Given:

A student used the proportion [tex]\dfrac{n}{100}=\dfrac{5}{26}[/tex] to find 5% of 26.

To find:

The student's mistake.

Solution:

Let 5% of 26 be n. Then,

[tex]n=\dfrac{5}{100}\times 26[/tex]

On dividing both sides by 26, we get

[tex]\dfrac{n}{26}=\dfrac{5}{100}[/tex]

So, the proportion used by the student was incorrect. The denominators of the proportion are interchanged.
