Answer:

m=80.840 kg

Step-by-step explanation:

Given Data,

Q=23000 J

c=4.184 J/g °c

Δt= 68 °c

m=?

By using this equation,

Q=mcΔt

23000=m\times 4.184\times 68\\\\m=\frac{23000}{4.184\times68} \\\\\\m=80.840 kg

Triangle RST has sides measuring 22 inches and 13 inches and a perimeter of 50 inches. What is the area of triangle RST? Round t
Nonamiya [84]

Answer:

Area of triangle RST = 95 in² (Approx)

Step-by-step explanation:

Given:

Side a = 22 in

Side b = 13 in

Perimeter = 50 in

Find:

Area of triangle

Computation:

Side c = Perimeter - Side a - Side b

Side c = 50 - 22 - 13

Side c = 15 in

Heron's formula:

s = Perimeter / 2 = 50 / 2

s = 25 in

Area of triangle = √s(s-a)(s-b)(s-c)

Area of triangle = √25(25-22)(25-12)(25-15)

Area of triangle = √25(3)(13)(10)

Area of triangle = 5√390

Area of triangle = 5 × 19(approx)

Area of triangle RST = 95 in² (Approx)

The carpet used in Parkers bedroom covers an area of 121 square feet. If the carpet is square, what is the length of each side o
steposvetlana [31]

The length of the carpet's side is 11 feet

Step-by-step explanation:

Step 1 :

The area covered by the carpet = 121 square feet

We need to find the length of side of  carpet

Step 2 :

Since it is given that the carpet is square, the length of all sides are the same

The area is obtained by squaring the side. Hence to find the side from the given area we need to take the root of the area.

Side²  = 121

Therefore side = √121 = 11 feet

Step 3 :

Answer :

The length of the carpet's side is 11 feet
