What is the surface area of a square pyramid with a height of 12 mm and a base that measures 8 mm on each side?

Answer:

1) Skewed left

2) About 33.333%

Explanation for 2; to find the percent, use the following steps:

First, add all the numbers together to find the total number of students

4 + 6 + 6 + 8 + 12 = 36

Then, divide 12 by 36

12 ÷ 36 = 0.3333....

Finally, multiply 0.3333.... by 100

0.3333.... × 100 = 33.333....%

Answer:

There are 144 Php 5-coins, 72 Php 10-coins and 130 Php-1 coins

Step-by-step explanation:

The amount of the coins in the coin bank = Php 1,570

The number of Php 5-coins = 2 × The number of Php 10-coins

The number of Php 5 coins = The number of Php 1-coins + 14

Let 'x' represent the number of Php-5 coins, let 'y' represent the number of Php 10-coins, and let 'z' represent the number of Php 1-coins, we get;

x = 2 × y...(1)

x = z + 14...(2)

5·x + 10·y + z = 1,570...(3)

From equation (1) equation (2), and equation three, we have;

y = x/2

z = x - 14

5·x + 10·x/2 + x - 14 = 1,570

11·x - 14 = 1,570

x = (1,570 + 14)/11 = 144

The number of Php 5-coins, x = 144

y = x/2

∴ y = 144/2 = 72

The number of Php 10-coins, y = 72

z = x - 14

∴ z = 144 - 14 = 130

The number of Php 1-coins, z = 130

Answer:

Step-by-step explanation:

range is the same since 20-8=12 and 14.5-2.5=12. The boys do have the greatest median though as three boys play for 10 hours.

boys: 15 - 8 = 7

girs: 15 - 3 = 12

so girls have greatest range

Median:

boys = 12

girls = 6.5

so boys have greatest median

answer:

first drop down: girls have greatest range

second drop down: boys have greatest median

Answer:

the answer above is correct!

Answer:

Step-by-step explanation:

Area of a rectangle is given as length times breadth. Mathematically,

A = l * b

If the length is halved and the breadth is constant, then we have

A = l/2 * b

A = lb/2

From the above, the area of a rectangle is lb, while the area of the hypothetical rectangle will be lb/2

This means that, if the length is halved, and the width is constant, then the area of the rectangle reduces by half.

Answer:

Option A

Step-by-step explanation:

Given :-

We need to find the relationship between a and b. Also we know that the measure of angle of straight line is 180 ° .

According to Question :-

[tex]:\implies[/tex] a + b + 90° = 180°

[tex]:\implies[/tex] a + b = 180° - 90°

[tex]:\implies[/tex] a + b = 90°

Answer:

Number one is 48 ft and number two is 92 in.

Answer:

[tex]5(x + 10)(10x - 3)[/tex]

Step-by-step explanation:

We are factoring

[tex]50x^{2} + 485x - 150[/tex]

So:

((2•5^2x^2) +  485x) -  150

Pull like factors :

50x^2 + 485x - 150  =   5 • (10x^2 + 97x - 30)

Factor

 10x^2 + 97x - 30

Step-1: Multiply the coefficient of the first term by the constant   10 • -30 = -300

Step-2: Find two factors of  -300  whose sum equals the coefficient of the middle term, which is 97.

-300    +    1    =    -299

     -150    +    2    =    -148

     -100    +    3    =    -97

     -75    +    4    =    -71

     -60    +    5    =    -55

     -50    +    6    =    -44

     -30    +    10    =    -20

     -25    +    12    =    -13

     -20    +    15    =    -5

     -15    +    20    =    5

     -12    +    25    =    13

     -10    +    30    =    20

     -6    +    50    =    44

     -5    +    60    =    55

     -4    +    75    =    71

     -3    +    100    =    97

Step-3: Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -3  and  100

                    10x^2 - 3x + 100x - 30

Step-4: Add up the first 2 terms, pulling out like factors:

                   x • (10x-3)

             Add up the last 2 terms, pulling out common factors:

                   10 • (10x-3)

Step-5: Add up the four terms of step 4:

                   (x+10)  •  (10x-3)

            Which is the desired factorization

Thus your answer is

[tex]5(x + 10)(10x - 3)[/tex]

Answer:

[tex] \displaystyle \rm 5({x}^{} + 10)( 10x - 3)[/tex]

Step-by-step explanation:

we would like to factor out the following expression:

[tex] \displaystyle {50x}^{2} + 485x - 150[/tex]

notice that, in every term there's a common factor of 5 thus factor it out:

[tex] \displaystyle 5( {10x}^{2} + 97x - 30)[/tex]

now we have to rewrite the middle term as sum or substraction of two different terms in that case 100x-3x can be considered:

[tex] \displaystyle 5( {10x}^{2} + 100 - 3x - 30)[/tex]

factor out 10x:

[tex] \displaystyle 5( 10({x}^{2} + 10)- 3x - 30)[/tex]

factor out -3:

[tex] \displaystyle \rm 5( 10x({x}^{} + 10)- 3(x + 10))[/tex]

group:

[tex] \displaystyle \rm 5({x}^{} + 10)( 10x - 3)[/tex]

and we are done!

hence,

our answer is B)

Answer:

Answer is 8

Step-by-step explanation:

Answer: 13.5

Step-by-step explanation:

54/4 = 13.5

13.5 x 4 = 54

The Pythagorean Theorem works only with right angle triangles. There are three sides: Side A, Side B, and the hypotenuse.

The formula for the Pythagorean Theorem is: a^2 + b^2 = c^2

To find the answer (without the exponent), you should find the square root.

Now that we have the formula, let's apply it to a triangle:

90^2 + 95^2 = c^2 =

8100 + 9025 = 17125

Square root = 130.86252328302

130.86252328302 is the exact measure of the hypotenuse.

Answer:

Start at origin (0,0)

Move 1/2 units left

Move 1 and 1/2 units down

Place your point

Step-by-step explanation:

Start at the origin (0,0)

Move 1/2 units to the left

Then move 1 1/2 units down, and place your point.

The first coordinate is locating the position horizontally, or on the x axis

The second coordinate is locating the position vertically, or on the y axis.

If there is a negative number on the x coordinate, the first one, you move left.

If positive, you move right.

If there is a negative number on the y coordinate, the second one, you move down.

If positive, you move up.

Answer:

Area of semicircle is

[tex] \frac{1}{2} (\pi \times {r}^{2} )[/tex]

If you are helped with my answer pls tag me brianliest I really want it

THANK YOU......

Answer:

To calculate the area of a semicircle

We are gonna have to use the formula :

[tex]\frac{1}{2}[/tex] π r² [ that is the formula to calculate the area of a semicircle ]

Step-by-step explanation:

If we want to calculate the radius of a semicircle with 4 ft --

we would first write the formula which is "[tex]\frac{1}{2}[/tex] π r²"

Then, you would write: [tex]\frac{1}{2}[/tex] π (4 ft)²

After that, you would write:  [tex]\frac{1}{2}[/tex] (3.14)(16)

Type that into a calculator and you would get 25.12  as your answer

--

Why did we write 3.14 and 16? [ [tex]\frac{1}{2}[/tex] (3.14)(16) ]

Bc, the first digits of pi are 3.14 .

We wrote 16 because 4² = 16 [ 4x4=16 ]

My explanation isn't that good so I would suggest watching the math antics video which is named "Circles, Circumference And Area"

Answer:

A. 92

Step-by-step explanation:

90 × 6 = 540

92 + 84 + 86 + 94 = 356

540 - 356 = 184

184/2 = 92

Answer:

x=4

Step-by-step explanation:

(5+x)(10+x)=126

50+5x+10x+x^2 = 126

x^2 + 15x +50=126

x^2 + 15x - 76 = 0

(x+19)(x-4) = 0

X=-19, 4

X=-19 is not possible

x=4

Answer:

0.26

Step-by-step explanation:

0.2 -> tenth

0.25 -> the 5 is the hundred place

0.257 -> the 7 is the thousand place.

Round the 7 and you get 0.26

Answer:

0.26

Step-by-step explanation:

To round 0.257 to the nearest hundreth, you'd have to look at the five and seven. Since seven is a higher number than four, you'd round the 5 up one, and get rid of the seven.
