If the given figure was folded into a
square pyramid, determine its lateral surface area.
A. 150cm2
B. 1,470cm2
C. 840cm2
D. 616cm2
E. 420cm2

Answer:

yes. by AAA, i think she mistyped an A not sure

Step-by-step explanation:

The remaining angle of the bigger triangle = 180 - 84.6 - 30.4 = 65 (angle sum of triangle)

The three angles are the same for both triangles

The triangles are similar to each other because the angle-angle theorem is satisfied.

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

The triangles are given.

Let the third angle of the triangle be x. Then we have

84.6° + 30.4° + x = 180

                        x = 65°

Then the triangles are similar to each other because the angle-angle theorem is satisfied.

Thus, the correct option is C.

Answer:

Greater than symbol.

2/3 > 2/4

Step-by-step explanation:

We have two fractions, 2/3 and 2/4

We then go back to the inequality part of mathematics where we have symbols such as greater than (>), less than (<), and equal to (=).

Of the three inequality symbols, we look and pick at the one that represents best, the fractions we were given.

2/3 and 2/4

With 2/3 being greater than 2/4.

2/3 = 0.67

2/4 = 0.50

Succinctly, 2/3 > 2/4.

Answer:sorry its c

Step-by-step explanation:

The mean value of Keisha’s data is 1.333333.

The mean is the average of a set of variables in mathematics and statistics. There are several methods for computing the mean, including the simple arithmetic mean (add up the numbers and divide the total by the number of observations),

We have the data,

0, 1, 0, 2, 2, 1, 3, 0, 4, 0, 1, 2.

So, the mean value of data is

= (0 +1 + 0 + 2 + 2 + 1 + 3 + 0 + 4 + 0 + 1 + 2)/12

= 16/12

= 4/3

= 1.33333

Answer:

y = -2x+3

Step-by-step explanation:

This is assuming you want the answer in slope-intercept (y = mx+b)

You need to know:

y = The line

m = The slope

b = The y-intercept

Step 1, replace the slope (m):

y = -2x+b

Step 2, replace the y-intercept (b):

y = -2x+3

Conclusion to 'complete the equation of the line whose slope is -2 and y intercept is (0,3)': y = -2x+3

Step-by-step explanation:

so first what you want to do is split the shape in to

Draw a line down where the 2 is.

you should have a rectangle and a triangle

then you find the area of the rectangle

Rectangle:

5 x 2 = 10m^2

After than you try to find the triangles area

the bottom of the triangle is 9m but since to split it in 2 you will now have 7m

multiple 5 times 7 and you will receive 35 then you divide that by 2 and you will have 17.5m^2

Add your two areas together and you will get 27.5m^2

Answer:

m = 10

Step-by-step explanation:

The values of w is inversely proportional to m

Mathematically:

w ∝ 1/m

w = k × 1/m

w = k/m

Where k is the Constant of Proportionality

Step 1

Solve for k

If w=8 then m=25

w = k/m

8 = k/25

Cross Multiply

k = 25 × 8

k = 200

Step 2

what is m when w=20? Show me the steps please

We solve for m

w = k/m

k = 200

20 = 200/m

Cross Multiply

20m = 200

m = 200/20

m = 10
