I'm pretty sure it would be 40,000 because if i'm not mistaken you meant the nearest 10,000 since the number is 39,892.
Answer:
1.you don't need to calculate 25²,7²,30² and 16² because you have a formula a²-b²=(a+b)(a-b)
OP²=MO²-MP²
OP²=25²-7²
OP²=(25+7)(25-7)
=32(8)
=256
OP=√256
OP=16 cm
NP²=NO²-OP²
NP²=30²-16²
=(30+16)(30-16)
=46(14)
=144
NP=√144
=12 cm
2.draw a straight line from the angle C and name that line with CE
CE=AD and AE=CD (because AECD is a rechtangular)
So EB=10-7 =3 cm
BC²=EC²+EB²
=4²+3²
=16+9
=25
BC=√25
=5 cm
for area of the square? i don't understand this question...
Answer:
The total cost of the framing for the painting is $0.40·P
Step-by-step explanation:
The first step to be done is to measure the length of the perimeter of the painting
Whereby the perimeter of the painting is p inches long, then the total cost of the framing will be found to be as follows
Total cost of framing = Cost per inch of framing × Perimeter of painting
∴ Total cost of framing = $0.40 × p
The total cost of the framing for the painting = $0.40·P.
Y=x+-3
The ? Is the y intercept
The y intercept is where the line meets the y axis
the answer is -3
Answer:
24″ width, 12″ length. Let the length be X inches, then width is 2X inches, giving perimeter 2(X+2X)=6X inches, which is 72″. hence X, length =12″, and width 24″. The perimeter of a rectangle is 64 m.
Step-by-step explanation:
