1 answer:

4 0

Answer: bh=4×5=20b, h, equals, 4, times, 5, equals, 20 square units, so the area of the triangle is \dfrac 12 bh = \dfrac 12 \times 4 \times 5 = 10

bh=

×4×5=10start fraction, 1, divided by, 2, end fraction, b, h, equals, start fraction, 1, divided by, 2, end fraction, times, 4, times, 5, equals, 10

A certain star is 2.4 x 102 light years from the Earth. One light year is about 5.9 x 1012 miles. How far

Studentka2010 [4]

Answer:

2.5 x $10^{15}$ miles

Step-by-step explanation:

We are given that 1 light year ≈ 5.9 x $10^{12}$ miles so:

4.3 x 10² light year · <u>5.9 x </u> $10^{12}$ <u> miles </u>
1 light year

Multiply 4.3 an 5.9 and round to 2 significant digits then add the exponents:

≈25 x $10^{14}$

This is not the scientific notation since the number is not between 0 and 10 so we move the decimal point by 1 place to the left. We then add 1 to the exponent to obtain the final answer:

≈ 2.5 x $10^{15}$ miles

A = 2√3 ft.;c = 4 ft.<br> A = 8√3 sq. ft.<br> True<br> False

Vladimir79 [104]

False . The equation a= 2√3 ft.;c = 4 ft is: A= 2√3 ft².

<h3>Area of the triangle</h3>

Given:

a = 2√3 ft,

c = 4 ft,

Lengths of the sides of a right triangle = a and b

Hypotenuse= c

Hence:

<h3>Using Pythagorean theorem</h3>

c²=a²+b²

4²=(2√3)²+b²

16=12+b²

4=b²

b=2

Area of triangle

A=1/2×a×b

A=1/2×2√3×2

A=4√3÷2

A=2√3 sq.ft

The Area of the triangle is 2√3 ft².
