Answer: 152

Step-by-step explanation:

Let the number = x.

Therefore, x*25% = 38

25% as a decimal is 0.25.

So, 0.25x = 38

We can divide both sides by 0.25:

x = 152

svlad2 [7]

Answer:

150 feet

Step-by-step explanation:

There are 10 marks between the 1st and 11th mark.

Since each mark represents 5 yards, 10 * 5 = 50 yards

Since 1 yard = 3 feet

50 yards = 50 * 3 = 150 feet

Mai is visiting Paris to see the Eiffel Tower. She is 80 feet away

Jlenok [28]

Answer: height of the tower is 1064 feet

Step-by-step explanation:

We want to determine the height of the tower.

Assuming her line of sight of the top of the tower is a straight line, then a right angle triangle is formed. The height, h of the tower represents the opposite side of the triangle. Her distance from the foot of the tower represents the adjacent side of the triangle.

To determine h, we would apply the tangent trigonometric ratio which is expressed as

Tan θ = opposite side/adjacent side

Therefore,

Tan 85.7 = h/80

h = 80tan 85.7

h = 1064 feet

Saturn is 8.867 × 10^8 miles away from the Sun. Uranus is 1.787 × 10^9 miles away from the Sun. Approximately how many times far

Over [174]

Answer:

2 times

Step-by-step explanation:

Please refer to the image attached of our solar system in which Saturn and Uranus are clearly visible.

Distance of Saturn from Sun, $D_{1} = 8.867 \times 10^{8}\ miles$

Distance of Uranus from Sun, $D_{2} = 1.787 \times 10^{9}\ miles$

We have to find, how many times the Uranus is far from Sun than Saturn is far from Sun.

Let us begin by multiplying the distance of Saturn from Sun by 2: $D_{1} \times 2 = 8.867 \times 10^{8}\ miles \times 2\\\Rightarrow 17.734 \times 10^{8}\ miles\\\Rightarrow 1.7734 \times 10^{1} \times 10^{8}\ miles\\\Rightarrow 1.7734 \times 10^{8+1}\ miles\\\Rightarrow 1.7734 \times 10^{9} $\approx$ D_{2}$

From above, we can say that $D_{2}$ is approximately twice of $D_{1}$ .

In other words, we can say that Uranus is at approximately twice distance from Sun than that of Saturn is.
