Answer 1

Answer:

the answer is \(\sqrt{5\\}\) , and - \(\sqrt{5\\}\) which is C.

Step-by-step explanation:

well I got that answer by doing this

we have \(x^{2}\)= 5

For \(x^{2}\)= f (a) the solutions are x = \(\sqrt{f(a)\\}\) , - \(\sqrt{f(a)\\}\)

so in this case the solutions are \(\sqrt{5\\}\), and - \(\sqrt{5\\}\)

Find the surface area of the regular pyramid. Write your answer as a decimal. (solved)

Answers

Answer:

The total surface area is 145.12 sq.m.

Step-by-step explanation:

We are supposed to find the surface area of given figure

Length of rectangular part = 15 m

Breadth of rectangular part = 8 m

Area of rectangular part =\(Length \times Breadth = 15 \times 8 = 120 sq.m.\)

Diameter of semi circle = 8 m

Radius of semicircle = \(\frac{8}{2}=4 m\)

Area of semicircle = \(\frac{\pi r^2 }{2}=\frac{3.14 \times 4^2}{2}=25.12 sq.m.\)

Total surface area = 120+25.12=145.12 sq.m.

Hence The total surface area is 145.12 sq.m.

what is the surface area of a rectangular prism with a length of 38 a width of 20 and a height of 20 show work please

Answers

Answer:

The surface area of a rectangular prism can be calculated using the formula:

Surface Area = 2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the rectangular prism, respectively.

Given the dimensions of the rectangular prism as:

Length (l) = 38

Width (w) = 20

Height (h) = 20

Substitute the values in the formula to get:

Surface Area = 2lw + 2lh + 2wh

Surface Area = 2(38)(20) + 2(38)(20) + 2(20)(20)

Surface Area = 1520 + 1520 + 800

Surface Area = 3840 square units

Therefore, the surface area of the rectangular prism is 3840 square units.

Answer:

3840

Step-by-step explanation:

A=2(wl+hl+hw)=2·(20·38+20·38+20·20)=3840

One friend solves
7(x + 4) = 49 by dividing each side
by 7 and then subtracting 4 from
each side. Another friend solves it by
first distributing the 7 on the left side
of the equation, then subtracting 28
from each side, and finally dividing
each side by 7. Which friend uses the
correct method? Explain.

Answers

Answer:

the second friend

Step-by-step explanation:

Answer:

both methods are correct

Step-by-step explanation:

Given

7(x + 4) = 49 ( divide both sides by 7 )

x + 4 = 7 ( subtract 4 from both sides )

x = 3

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

Given

7(x + 4) = 49 ← distribute parenthesis by 7

7x + 28 = 49 ( subtract 28 from both sides )

7x = 21 ( divide both sides by 7 )

x = 3

As shown both methods are equally valid

Answer:

Step-by-step explanation:

-3(3x-3)=4/5(5x-10)

-9x+9=4x-8

-13x= -17

x=17/13

Answer:

\(1\frac{4}{13}\)

Step-by-step explanation:

-3 (3x-3) = 4/5 (5x-10)

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

This also equals to:

-3*(3x-3)=4/5*(5x-10)

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

Start by opening the parentheses:

-3*(3x-3)=4/5*(5x-10)

Then use distributive property:

(-3*3x) + (-3*-3)= (4/5*5x) + (4/5*-10)

Simplify the equation:

(-3*3x) + (-3*-3)= (4/5*5x) + (4/5*-10)

-9x+9= 4x-8

    +8       +8

-9x+17= 4x

+9x      +9x

17= 13x

Three friends each have some ribbon. Carol has 90 inches of ribbon, Tino has 4.5 feet of ribbon, and Baxter has 4.5 yards of ribbon. Express the total length of ribbon the three friends have in inches, feet, and yards.

Answers

Answer:
Total inches: 306
Total feet: 25.5
Total yards: 8.5

Explanation:
90 inches converted to inches= 90 inches
4.5 yards converted to inches= 162 inches
4.5 feet converted to inches= 54 inches
90 + 162 + 54= 306 inches

90 inches converted to feet= 7.5
4.5 yards converted to feet= 13.5
4.5 feet converted to feet= 4.5
7.5 + 13.5 + 4.5= 25.5 feet

90 inches converted to yards= 2.5
4.5 yards converted to yards= 4.5
4.5 feet converted to yards= 1.5
2.5 + 4.5 + 1.5= 8.5 yards

Answer:

Step-by-step explanation:

Let's convert every measurement into inches for now.

90 inches = 90 inches

4.5 feet = 54 inches

4.5 yard = 162 inches

Now, 90 + 54 + 162 = 306 inches

90 inches = 7.5 feet

4.5 feet = 4.5 feet

4.5 yard = 13.5 feet

Now, 7.5 + 4.5 + 13.5 = 25.5 feet

90 inches = 2.5 yards

4.5 feet = 1.5 yards

4.5 yards = 4.5 yards

Now, 2.5 + 1.5 + 4.5 = 8.5 yards

Answer:

Mean = 33.7

Median = 34.5

Mode = 34

Range = 33

After adding 26....


mean decreases by 0.7

median decreases by 0.5

mode is 34

range is 33

Step-by-step explanation:

mean = sum of all the data values/number of data values

= (18 + 19 + 20  + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7

To find median arrange the values in increasing order, find the mid value

If the number of data points is even, find the average of the mid 2 data values

Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51

Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5

The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once

Mode = 34

The range is highest - lowest = 51 - 18 = 33

After we add 26, we get the following data set arranged

18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51

we can calculate the stats using the same technique as above

We get the following values

mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33  

median = 34

mode = 34

range = 51-18 = 33

To find the decrease in mean and median subtract from the first set of values

Answer:

B. 67°

Step-by-step explanation:

Step 1: Find m∠B

180 - (48 + 19) = 113°

Step 2: Use Supplementary Angles rules

180 - 113 = 67°

Answer:

m<ABD is 113 degrees

Step-by-step explanation:

The interior angles of a triangle must add up to 180 degrees.

Representing angle ABD by x, we have:

x + 48 degrees + 19 degrees => x + 67 degrees = 180 degrees.

Subtracting 67 degrees from boths sides, we get x = 113 degrees.

m<ABD is 113 degrees.
