The side lengths of a triangle are 5,√3,√28. Is the triangle a right triangle? How would I solve this?

Answers

I’m not good at explaining but I’ll try.

Legs: 5, √3. Hypotenuse: √28

So your legs are: a and b, and ur hypotenuse is c

a^2+b^2=c^2
Which means

5^2+√3 has to equal to √28^2.

Let’s solve it

5^2+√3^2= √28^2

= 25+3=28

28=28

So that is a right triangle.


First to Answer:

The triangle would be a cute Scalene Triangle!

Here's all that you really can do with solving that

√28 =5.29150262213

√8 = 2.82842712475

Side a = 2.8

Side b = 5

Side c = 5.2

Angle ∠A = 31.788° = 31°47'18" = 0.55481 rad

Angle ∠B = 70.167° = 70°10'0" = 1.22464 rad

Angle ∠C = 78.045° = 78°2'42" = 1.36214 rad

Area = 6.84817

Perimeter p = 13

Semiperimeter s = 6.5

Height ha = 4.89155

Height hb = 2.73927

Height hc = 2.63391

Median ma = 4.9051

Median mb = 3.34515

Median mc = 3.10805

Inradius r = 1.05357

Circumradius R = 2.65764

Vertex coordinates: A[0, 0] B[5.2, 0] C[4.25, 2.63391]

Centroid: [3.15, 0.87797]

Inscribed Circle Center: [3.7, 1.05357]

Simon makes a model of a boat, using a scale of 1 : 30


If the model has a height of 40 cm, find the height of the real boat.


Give your answer in metres.

Answers

Answer: 12 metres

Step-by-step explanation:

The scale factor used for the model is 1 : 30.

This means that for any 1cm on the model, the real boat would be 30 cm.

If the height is 40 cm on the model, the real boat will be 30 times that:

= 40 * 30

= 1,200 cm

A metre is equivalent to 100cm.

1,200 cm would therefore be:

= 1,200/100

= 12 metres

a case of fruit weighs 53 kilogram and another weighs 47 kilograms how much weight must be removed from the first case and placed in the second is that they both equal

a . 2 kilograms
b . 4 kilograms
c . 6 kilograms
d . 8 kilograms ​

Answers

None of those it will be 3

There are 3 kilograms weight must be removed from the first case and placed in the second is that they both equal.

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

Fruit weight = 53 kilograms

And, Another weight = 47 kilograms

Now,

Let number of kilograms weights to remove and add = x

So, We can formulate;

⇒ 53 - x = 47 + x

Solve for x as;

⇒ 53 - 47 = x + x

⇒ 6 = 2x

⇒ 2x = 6

⇒ x = 3

Thus, There are 3 kilograms weight must be removed from the first case and placed in the second is that they both equal.

Which expression rrepresents the length of QR ?


helpppp

Answers

Answer:

QR = 4x - 6

Step-by-step explanation:

A triangle is a polygon that has three sides and three angles. There are different types of triangles such as equilateral triangle, isosceles triangle, scalene triangle, right angled triangle.

The perimeter of a triangle is a measure of the length of the sides. It is the sum of all the length of the three sides of the triangle.

From the question:

Perimeter of triangle PQR = PQ + PR + QR

But PR = 3x - 1, PQ = x + 1, Perimeter of PQR = 8x - 6.

Therefore substituting gives:

8x - 6 = (x + 1) + (3x - 1) + QR

8x - 6 = (x + 3x + 1 - 1) + QR

8x - 6 = 4x + QR

QR = (8x - 6) - 4x

QR = 4x - 6

Angle ABF is 120°.

Step-by-step explanation:

Vertical angles are used to get the measure of angle ABG (3x) and FBE (2x) and all of those added together are 180. Then you use PEMDAS to get x. Then you find ABF by multiplying 3 by 30 (what you get when you use PEMDAS to find x) then you add 30 to that and you get 120.

Cost = Price per cookie * Number of cookies

On comparing

Cost per cookie = $0.50

Hence,

Option C : $0.50 per cookie is the right answer.

$213 ski jacket with a 30% discount and a 6% tax

Answers

$158.046

Take the discount off first, 213*.70=149.10, then multiply 149.10*1.06= $158.046

158.04$.

What is discount?

A discount is a decrease in the cost of a commodity or service. If the item is broken, you can ask the manager for a discount.

Given the Written price of the ski jacket is 213$ on that there is a discount of 30% and 6% of tax. Hence,

discounted price of jacket = 213 (1- 30%)

discounted price of jacket = 149 approx.

Total price of the jacket after-tax = 149 (1 + 6%)

The total price of the jacket after-tax = 158.04$

Therefore, the price of a $213 ski jacket with a 30% discount and a 6% tax is 158.04$.
