The triangular prism shown below is 6 \,\text{cm}6cm6, start text, c, m, end text wide and 4\,\text{cm}4cm4, start text, c, m, end text deep. The vertical height is 7\,\text{cm}7cm7, start text, c, m, end text. What is the length of the side edge, sss, of the triangular prism?

Answers

Answer:

The answer is "7.62 cm ".

Step-by-step explanation:

Given:

[tex]Width = 6\ cm \\\\Depth = 4 \ cm\\\\Vertical \ height = 7 \ cm\\\\[/tex]

Dividing the prism's face into two halves:

As just a result, the vertical height becomes 7cm, as well as the width, becomes [tex]\frac{6\ cm}{2} = 3 \ cm[/tex]. If the 's' on both sides of the edge is equal:

[tex]s^2 = width^2 + height^2\\\\[/tex]

   [tex]= \sqrt{(width^2 + height^2)}\\\\[/tex]  

   [tex]= \sqrt{(3^2 + 7^2)}\\\\= \sqrt{9 + 49}\\\\= \sqrt{58}\\\\= 7.62 \ cm[/tex]

Answer:

56.54in^2

Step-by-step explanation:

Answer:

18π in^2 (roughly 56.5 in^2)

Step-by-step explanation:

The area of a semicircle is half the area of a circle. So the area would be 1/2πr² instead of πr².

Since the diameter is 12 inches, the radius would be half of that, making the radius r=12/2=6 inches.

Plugging in r=6 into our formula, we see that the area of the semicircle is 1/2π(6)²=1/2π(36)=18π inches^2

So your final area is 18π in^2 (roughly 56.5 in^2)

The ratio of the number of games won to the number of games lost (no ties) by the Middle School Middies is
11/4. To the nearest whole percent, what percent of its games did the team lose?

Answers

Answer:

27%

Step-by-step explanation:

The ratio means that for every 11 games won, 4 are lost, so the team has won 11x games, lost 4x games, and played 15x games for some positive integer x. The percentage of games lost is

4x / 15x * 100 = 4/15 * 100 = 26.6666 = 27%

A percentage is a way to describe a part of a whole. To the nearest whole percentage, the percentage of games lost by the team is 27%.

What are Percentages?

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Given the ratio of the number of games won to the number of games lost is 11/4, therefore, the total number of games played by the team is 15(11+4).

Now, the percentage of games lost by the team is,

4/15 × 100% = 26.6667% ≈27%

Hence, To the nearest whole percentage, the percentage of games lost by the team is 27%.

Volume = rule area × height

__________________________

The rule is circle and the area of the circle finds using following formula :

Circle area = pi × radius^2

Circle area = 3.14 × 1^2

Circle area = 3.14

___________________________

Volume = 3.14 × 10

Volume = 31.4 in^3

The volume of cylinder having diameter 1 inches and height be 10 inches be 31.4 cubic inches.

What is volume?

Volume is amount of substance a container can hold in its capacity. Volume of cylinder is π[tex]r^{2} h[/tex] in which r is radius and h is height of cylinder.

How to calculate volume?

We have been given that the diameter of cylinder be 2 inches and height be 10 inches.We have to find the volume of cylinder.

Volume of cylinder=π[tex]r^{2} h[/tex]

Radius=2/2

=1 inch

Now put the value of radius and height in the formula of volume.

Volume=3.14*1*10

=31.4 cubic inches.

Hence the volume of cylinder is 31.4 inches.

Answer : 45 degrees

Explanation: it forms a right triangle and a right triangle is 90 degrees and the other half is 45 so that means the 2nd half is 45 degrees

Answer:

b=45

Step-by-step explanation:

The two angles form a right angle. This is shown through the box drawn at the angle's vertex; this represents that it is a right angle. A right angle is equal to 90 degrees b can be found by using the other angle. Since 45 and b are complementary angles 45+b=90. This means that b must equal 45 degrees.

5x + 7y = 25
5x - 2y = -65
solve using elimination
(step by step please)

Answers

5x+7y=25

5x-2y=-65

subtract both of the equations

5x-5x=0

7y--2y= 7y+2y=9y

25--65=25+65=90

0+9y=90

9y=90

divide both sides by 9 to get y by itself

9y/9=90/9

cross out 9 and 9 which becomes 1*1*y=y

90/9=10

y=10

find x by using the substitution method

5x+7y=25

5x+7(10)=25

5x+70=25

move +70 to the other side

sign changes from +70 to -70

5x+70-70=25-70

5x=-45

divide both sides by 5 to get x by itself

5x/5=-45/5

cross out 5 and 5 then becomes 1*1*x=x

-45/5=-9

x=-9

(-9,10)
