The perimeter of a rectangular field is 264 yards. If the width of the field is 54 yards, what is its length?
SIZIF [17.4K]
P = 2(L + W)
P = 264
W = 54

264 = 2(L + 54)
264 = 2L + 108
264 - 108 = 2L
156 = 2L
156/2 = L
78 <=== Length is 78 yards

A flag pole has a rope that attaches to the ground from the top of the flagpole the rope create a 30° angle with the ground and
OLEGan [10]

Answer:

5.77\ \text{m}

11.54\ \text{m}

Step-by-step explanation:

p = Height of pole

h = Length of role

b = Distance between the bottom of the rope and bottom of the pole = 10 m

\theta = Angle between the rope and the ground = 30^{\circ}

\tan\theta=\dfrac{p}{b}\\\Rightarrow p=b\tan\theta\\\Rightarrow p=10\tan30^{\circ}\\\Rightarrow p=5.77\ \text{m}

The length of the rope is 5.77\ \text{m}

\cos\theta=\dfrac{b}{h}\\\Rightarrow h=\dfrac{b}{\cos\theta}\\\Rightarrow h=\dfrac{10}{\cos30^{\circ}}\\\Rightarrow h=11.54\ \text{m}

The length of the pole is 11.54\ \text{m}

Order the fractions from least to greatest.
tresset_1 [31]

Answer:

B. 3/7, 3/5, 3/4

Step-by-step explanation:

When ordering the fractions from least to greatest make sure they have the same denominator,

It is hard to compare fractions that don't have the same denominator!

3/7, 3/5, 3/4,

Denominators: 4, 5, and 7,

For the denominators (4, 5, 7) the least common multiple (LCM) is 140,

Calculations to rewrite the fractions as equivalent fractions with the LCD:

3/4 = 3/4 × 35/35 = 105/140

3/5 = 3/5 × 28/28 = 84/140

3/7 = 3/7 × 20/20 = 60/140

Now compare and order them,

105 is the greatest value,

60 is the smallest value,

60/140, 84/140, 105/140,

3/7, 3/5, 3/4,

Therefore option B is the answer.
