Find the Surface area

Answer:

532 m ^2

Step-by-step explanation:

18x18 + 1/2x8x 16 + 1/2 x 16 x18

324 + 64+ 144 = 532

Answer:

A

Step-by-step explanation:

Answer: The answer is A

Since we are dilating by 1/2 the image must get smaller. Now that we know that you can divide the side lengths by 2 (or multiply by 1/2) to get A'B' equals 17. Angles measures don't change during dilation because it only affects the side lengths, so angle A' is still 28 degrees

Hope this helped you!

Answer:

√{387×387}=√387²=387 is your answer

Answer:

#2:

To get rid of a radical we multiply the radical by itself, so we multiply [tex]\frac{3}{\sqrt{2}} by \frac{\sqrt{2}}{\sqrt{2}}[/tex]

to get [tex]\frac{3\sqrt{2}}{2}[/tex].

#3:

[tex]\sqrt\frac{2}{5}[/tex] is the same as [tex]\frac{\sqrt{2}}{\sqrt{5}}[/tex] so we multiply by [tex]\frac{\sqrt{5}}{\sqrt{5}}[/tex] so we get [tex]\frac{\sqrt{10}}{5}[/tex].

#4:

We combine like terms to get  [tex]-2\sqrt{2} + 4\sqrt{3}[/tex]

Answer:

a. 1.5

b. 0.2

c -1.9

Step-by-step explanation:

The computation of the z scores of each of the following data values are as follows:

As we know that

z = (data values - mean)÷ standard deviation

Now

a. The z value is

= (40 - 25) ÷ (10)

=  1.5

b. The z value is

= (27 - 25) ÷ 10

= 0.2

c. The z value is

= (6 - 25) ÷ 10

= -1.9

Answer:

g(n) = 18 - 4n

Step-by-step explanation:

Given the recursive formula

g(n) = g(n - 1) - 4 with common difference d = - 4 and g(1) = 14

The explicit formula for an arithmetic sequence is

g(n) = g(1) + (n - 1)d , then

g(n) = 14 - 4(n - 1)

       = 14 - 4n + 4

       = 18 - 4n

Answer:

m= −2 /7

Step-by-step explanation:

Let's solve your equation step-by-step.

6m+1m=−2

Step 1: Simplify both sides of the equation.

6m+1m=−2

6m+m=−2

(6m+m)=−2(Combine Like Terms)

7m=−2

7m=−2

Step 2: Divide both sides by 7.

7m /7 = −2 /7

Answer: [tex]\dfrac{2}{87}[/tex]

Step-by-step explanation:

Given

Lennox marks 30 papers to represent the dates

He has to choose two papers marked 1 to 5 to get the appointment within the first five days of November

This can be done in [tex]^5C_2[/tex] ways

The total no of ways is [tex]^{30}C_2[/tex]

Probability is

[tex]\Rightarrow P=\dfrac{^5C_2}{^{30}C_2}=\dfrac{5\times 4}{30\times 29}\\\\\Rightarrow P=\dfrac{2}{87}[/tex]

Answer:

Perimeter of ABCD = 56 units

Perimeter of WXYZ = 140 units

Step-by-step explanation:

To find the perimeter of ABCD, find the sum of all sides

18 + 18 + 10 + 10 = 56

To find the side lengths of WXYZ, use the equation:   [tex]\frac{image}{pre-image}[/tex]

45/18 = 2.5

You can also cross multiply to find the missing side lengths, but I'll show you this other way...

Multiply the pre-image side lengths by 2.5

18 × 2.5 = 45

10 × 2.5 = 25

45 and 25 of the new side length of WXYZ

To find the perimeter of  WXYZ, find the sum of all sides.

45 + 45 + 25 + 25 = 140

WX = 45, XY = 25, YZ = 45, ZW = 25

Answer:

[tex]23^{o}[/tex] and [tex]23^{o}[/tex]

Step-by-step explanation:

An isosceles triangle has two of its sides and angles to be equal. Let each of the unknown equal angles be represented by x. Since one of its angles measures  134°, then;

x + x +  134° = [tex]180^{o}[/tex]

2x + 134° = [tex]180^{o}[/tex]

2x = [tex]180^{o}[/tex] - 134°

    = 46

x = [tex]\frac{46}{2}[/tex]

  = [tex]23^{o}[/tex]

x = [tex]23^{o}[/tex]

The other angles that could be in the isosceles triangle are [tex]23^{o}[/tex] and [tex]23^{o}[/tex].

Answer:

the answer is going to be 0.35 cents to find the answer all you gotta do is divide 4.20 by 12 ☺ ☺ ☺ ☺ ☺

Mean is average. Multiply total books by the mean to find the total cost:

5x 10 = $50 total.

Subtract the highest and lowest prices to find the total of the remaining 3 books.

50 - 15-6 = 29

The median price was 8, this is the middle number, subtract 8 from 29 to get the cost of the last 2 books:

29-8 =21

Now you need a price lower than the median but higher than the lowest cost so that has to be 7

Subtract 7 from 21 to get the cost of the last book 21-7 = 14

The price of the remaining books is $7 and $14

Answer:

23

Step-by-step explanation:

divide -4 by -44 and you get 11, add 12 because 12 was taken away and you get 23. 11+12=23 23-12=11

Answer:

(2,-7)

Step-by-step explanation:

Plug the first equation into the second equation.

4x+3(2x-11)=-13

4x+6x-33=-13

10x=20

x=2

Now, plug the value of x into one of the equations in order to find y.

y=2(2)-11

y=4-11

y=-7

Answer:

Savings= $236

Step-by-step explanation:

Giving the following information:

Money spent= $59

Proportion of savings= 25% = 0.25

To calculate the total savings before shopping, we need to use the following formula:

Savings= money spent / proportion of savings

Savings= 59 / 0.25

Savings= $236

Step-by-step explanation:

120° because opposite angles of parm are equal
