Answers

1. Equilateral

3. Scalene
4. Right
5. Acute
6. Obtuse

The triangles are classified below.

What is a triangle?

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

An equilateral triangle is a triangle where all three sides are equal.

The right triangle is a triangle where one angle is 90 degrees.

An isosceles triangle is a triangle where two sides are equal.

An obtuse triangle is a triangle where the angle is greater than 90 degrees

An acute triangle is a triangle where the angles are less than 90 degrees.

A scalene triangle is a triangle where all three sides are different.

Now,

Side 5 cm, 5 cm, 5 cm, and 5 cm is an equilateral triangles.

Since all the sides are the same.

Sides of 3 cm, 5 cm, and 5 cm is an isosceles triangle.

Since the two sides are the same.

Sides of 3 cm, 5 cm, and 7 cm is a scalene triangle.

Since all three sides are different.

Angles of 40°, 50°, and 90° is a right triangle.

Angles of 40°, 60°, and 80° is an acute triangle.

Angles of 40°, 40°, and 100° is an abtuse triangle.

Thus,

The triangles are classified above.

Step-by-step explanation:

x and y are inversely proportional (that is, x and y vary inversely). When x=2/3 then y=6. The value of x, when y=0.5, is ___________.

Answers

Answer:

x = 8

Step-by-step explanation:

inversely proportional expression:  y = k/x where 'k' is the constant of variation

input x and y values to find 'k'

y = k/x

6 = k ÷ 2/3

6 = k · 3/2

cross-multiply:  3k = 12;  so, k = 4

now input 4 for k and 0.5 for y to find x:

0.5 = 4/x

0.5x = 4

x = 8

Answer:

approx 72 feet

Step-by-step explanation:

the left and bottom sides of the quadrilateral are easy to see that their sum is 15 + 20 or 35

however, from (40, 30) to (45, 40) you can use the distance formula

d = √(y - y)² + (x - x)²

d = √10² + 5²

d = √125 which is approx 11.1

from (20, 40) to (45, 40) you get:

d = √5² + 25²

d = √650 which is approx 25.5

A store owner spends 7x + 13 dollars on two orders of boxes of light bulbs, including shipping.

10x + 18
4x + 8
21x + 65
10x + 8
Part B
If the store owner spent a total of $90 on both orders, how much does a box of light bulbs cost in dollars? Enter the number in the box.

Answers

Answer:

[tex]B = 4x + 8[/tex]

A box = $11

Step-by-step explanation:

Given

[tex]Total = 7x + 13[/tex]

Represent the first order with A and the second with B.

So, we have:

[tex]A = 3x + 5[/tex]

Solving (a): Find B.

To find B, we make use of:

[tex]A + B = Total[/tex]

Make B the subject

[tex]B = Total - A[/tex]

Substitute values for Total and A

[tex]B = 7x + 13 - (3x + 5)[/tex]

Open bracket

[tex]B = 7x + 13 - 3x - 5[/tex]

Collect Like Terms

[tex]B = 7x - 3x + 13 - 5[/tex]

[tex]B = 4x + 8[/tex]

Solving (b): Cost of a box of light bulb

This means that:

[tex]Total = 90[/tex]

Substitute 7x + 13 for Total

[tex]7x + 13 = 90[/tex]

Collect Like Terms

[tex]7x = 90 - 13[/tex]

[tex]7x = 77[/tex]

Make x the subject

[tex]x = \frac{77}{7}[/tex]

[tex]x = 11[/tex]

Find the cost of 80 Orange at 5 for 30 naria

Answers

By selling 80 oranges a man gains a cost price of 20 oranges. What is the gain percentage?
To solve this tricky question, let the cost price (CP) of an orange is 1 Rs.

Now CP of 80 oranges = 80 Rs………..(1)

And we know that

Profit= SP (selling price) - CP (cost price)

Here;

Profit = SP of 80 oranges - CP of 80 oranges…….(2)

{Here profit is already given that is CP of 20 oranges }

By (2);

CP of 20 oranges = SP of 80 oranges - CP of 80 oranges

Or

CP of 100 oranges = SP of 80 oranges

Or

SP of 80 oranges = 100 Rs…………(3)

{ cp of 1 orange is 1 Rs.}

Here we have

CP = 80 rs.

SP = 100 rs.

% profit = (SP - CP)*100/CP

% profit = (100–80)*100/80 = 20*100/80 = 25%

So %profit is 25%
