Answer:

Step-by-step explanation:

In order for a triangle to be a right triangle, it has to fit into Pythagorean's Theorem:

[tex]a^2+b^2=c^2[/tex] where c is the hypotenuse.

We need to figure out which is the longest side in each of those triangles and that is the hypotenuse.

In the first set, the sqrt of 443 is 21.04, but that is not the longest side; 24 is. So the Theorem formula for that is:

[tex]\sqrt{443}^2+17^2=24^2[/tex] which gives us

443 + 289 = 576, but 732 does not equal 576, so that one is not right.

In the second set, the sqrt of 725 is the longest side, so that formula is:

[tex]\sqrt{725}^2=14^2+23^2[/tex] which gives us

725 = 196 + 529, and 725 does equal 725, so that one is right.

In the third set, the sqrt of 890 is the longest side, so:

[tex]\sqrt{890}^2=19^2+23^2[/tex], which gives us

890 = 361 + 529, and 890 = 890, so that is a right triangle as well. That's how you know those are right, compared to the first one that is not.

Step-by-step explanation:

Given

[tex]L = 6in[/tex] --- Base length

[tex]H = 10in[/tex] --- Slant height

Shape: Square Pyramid

Required

Determine the surface area

This is calculated using:

[tex]Area = L^2 +2LH[/tex]

So, we have:

[tex]Area = 6^2 + 2 * 6 * 10[/tex]

[tex]Area = 36 + 120[/tex]

[tex]Area = 156in^2[/tex]

z = 18/6

z = 3

Answer:

7529.536

Step-by-step explanation:

√384=19.6

19.6, is therefore the length of one side

Volume of cube is length³

19.6³=7529.536

Well it's just a try for me

The volume of the box when there is the cube shaped box wrapped and it should measured 384 square inches so it is 7529.536.

Since

A cube-shaped box can be wrapped completely in gift wrap that measures 384 square inches

So here the side should be like

[tex]= \sqrt{384}[/tex]

= 19.6

Now the volume of the box should be

= [tex]19.6^3[/tex]

= 7529.536

hence, The volume of the box should be considered as the 7529.536.

Answer: Slope means the gradient. So find the equation of the line first then graph the points on the graph.

Step-by-step explanation:

y=mx+c                 *We want m*

m=(y2-y1)/(x2-x1)

m=(0-1)/(6-3)

m=-1/3

y=-1/3x+2          *(0,2) co-ordinate means it's the y-intercept=c*

I think the slope is -1/3 and then just plt the points on the graph manually.

Step-by-step explanation

cross-section is 10 inches by 16 inches

area = 10*16 = 160 square inches

The area of the shown cross-section is 160 square inches.

As you can see in the image, the cross-section of a rectangular prism is actually a rectangle.

Here, the dimensions of the rectangular cross-section is:

L  = 16 in

H = 10 in

The area will be the product of these two values, so we will get:

A = L*H = (16 in)*(10 in) = 160 in^2

So the area of the shown cross-section is 160 square inches.

Apply the radical rule to separate terms:

Cubicroot(-27) and cubic root(n^27)

Cubicroot(-27) = -3

Now you have -3 cubicroot(n^27)

Using the exponent rule

N^27 can be rewritten as (n^9)^3

Now you have -3 cubicroot((n^9)^3)

The cubic root and the 3rd power cancel out to get the final answer of

-3n^9

sons = x+6 = 11

Step-by-step explanation:

-6:

father's age = 6x

sons age = x

Present age =

fathers= 6x+6

sons = x+6

+4 yrs:

father's age = 6x+6 +4 = 6x + 10

sons age = x+6 + 4 = x+ 10

3(6x +10) = 8( x + 10 )

18x+30 = 8x+80

18x-8x = 80-30

10x = 50

x= 50/10 = 5

Step-by-step explanation:

To obtain a rounded value of $28 (to nearest dollar) the lowest and highest possible value before rounding will be : 27.50 and 28.49

Hence,

Lower bound = $27.50

Upper bound = $28.49

Therefore. Cost of making 450 chairs ;

27.50 * 450 = $12,375 (lower bound)

28.49 * 450 $12820.50 (upper bound)

Answer:

Step-by-step explanation:

m1+m2=180

3x+x+44=180

4x+44=180

4x=136

x=34

m1=3x=3(34)

m1=102 degrees

m2=x+44=34+44

m2=78 degrees

Answer:

The two angles added together are equal to 180 degrees because they lie on a straight line and a straight line is always equal to 180 degrees.

∠1 + ∠2 = 180°

∠1 = 3x, ∠2 = x + 44

Substitute the values of ∠1 and ∠2

3x + x + 44 = 180

4x + 44 = 180

4x = 136

x = 34

If x = 34,

∠1 = 3 * 34 = 102°

∠2 = 34 + 44 = 78°

First do inside the parentheses:

4 + [8/1 + 6-12] . 10

Now work inside the brackets doing division first

4 + [8 + 6 -12]. 10

Still inside the brackets add an subtract from left to right:

4 + 2 . 10

Multiply:

4 + 20

Add to get final answer of 24

Answer:

4+[8 ÷(8-7) +6 -12] . 10

4+[8÷1+6-12].10

4+[8+6-12].10

4+[14-12].10
