the height of a house having three rooms of the dimensional 9 feet into 12 feet 14 feet into 16 feet and 12 feet into 14 feet re

Semmy [17]

Answer:

Amount required = 2,217,600

Step-by-step explanation:

Dimensions of the rooms are as follows;

Room 1; 9 feet × 12 feet

Room 2; 14 ft × 16 ft

Room 3; 12 ft × 14 ft

Perimeter of rooms;

P1 = 2(9 + 12) = 42 ft

P2 = 2(14 + 16) = 60 ft

P3 = 2(12 + 14) = 52 ft

Total perimeter; P = 42 + 60 + 52 = 154 ft

Height is 90 ft.

Thus, total area is;

A = 154 × 90

A = 13860 ft²

Rate of painting is 160 per Sq.ft.

Thus amount to paint entire area = 160 × 13860 = 2217600

Help asap please!!!!

Alexxx [7]

Answer:

(3, 1)

Step-by-step explanation:

Let the coordinates of B be (x, y)

Since, M is the midpoint of AB.

Therefore, by mid point formula:

$1 = \frac{ - 1 + x}{2}, \: \: \: 3 = \frac{5 + y}{2} \\ \\ 2 = - 1 + x, \: \: \: 6 = 5 + y \\ \\ 2 + 1 = x, \: \: \: 6 - 5 = y \\ \\ 3 = x, \: \: \: 1 = y \\ \\ x = 3, \: \: \: y = 1 \\ \\ B = (3, \: \: 1)$

PLEASE HELP ITS DUE TODAY URGENT!

vlada-n [284]

Step-by-step explanation:

7. ∆ABC = ∆ILH by SSS

as, AB = IL , BC = LH , CA = HI

8. ∆DEF = ∆AMS by ASA

as , angle D = angle A, EF = MS , angle F = Angle S

9. ∆JKL = ∆HAT by SAS

as, JK = HA , KL = AT , angle L = angle T

10. ∆ABC = ∆KPG by ASA

as , CA = GK, Angle c = angle G and Angle B = angle P

11. ∆ABC = ∆YDE by ASA

as , angle A = angle Y, AB = YD , angle B = angle D

12. ∆MNO = ∆SAK by ASA

as , Angle M = angle S, NO = AK, angle O = angle K

hope this answer helps you dear...and may u have a great day ahead!

It took every 55 minutes to run a 10-meter race last weekend. If you know that 1 kilometer equals 0.621 mile, how many minutes d

Umnica [9.8K]

Velocity=distance/time
Data:distance=10 Km=10 km*(0.621 miles/1 km)=6.21 miles.time=55 minutes
Velocity=6.21 miles/55 minutes=0.11290909... miles/minute≈0.113 miles/ minute
Data: distance=1 mile.velocity=0.113 miles/minute
time=distance /velocitytime=(1 mile) / (0.113 miles/ minute)=8.85668... minutes≈8.86 minutes.
Answer: D 8.86 minutes.
