Answer:
Step-by-step explanation:
Mr. Rives' rotating sprinkler waters his lawn up to a radius of 7 feet. The formula for determining the area of a circle is expressed as
Area = πr²
Where
π is a constant whose value is 3.14.
r represents the radius if the circle.
The area covered by one of Mr. Rives' rotating sprinkler would be
3.14 × 7² = 3.14 × 49 = 153.86ft²
Therefore, the maximum area of lawn that two sprinklers can cover would be
153.86 × 2 = 307.72 ft²
Answer:
- Francesca: 2879 1/6 miles
- Sophia: 575 5/6 miles
Step-by-step explanation:
For each mile that Sophia ran, Francesca ran 5 miles. Then Sophia ran 1/6 of their total. Sophia ran ...
(1/6)(3455) = 575 5/6 miles
Francesca ran the remaining miles:
3455 -575 5/6 = 2879 1/6 miles
<span>Let </span>
<span>X= the altitude of the lighthouse above sea
level= 80 ft</span>
A = the angle of depression
Y= the distance of the boat from the lighthouse= 400 ft
tan A=X/Y------------------ >
80/400=0.2
arctan (0.2)=11.31 degree
The answer is the angle of depression is 11 degree
Answer:
-7
Step-by-step explanation:
Let the number be represented with 'Y'
Half of the number will be = Y/2
The difference of half of a number and 3
= Y/2 - 3
Is equivalent to negative 5
That is,
Y/2 - 3 = -5
y/2-3/1 = -5/1
Collect like terms
y/2 = -5/1+3/2
y/2 = -7/2
Multiply both sides by 2
y/2 ×2 = -7/2×2
Y = - 7
Hence the number is negative 7
<h3>
Answer: 22 (choice C)</h3>
Work Shown:
IQR = Q3 - Q1
IQR = 70 - 48
IQR = 22
Note: Q1 and Q3 are the left and right edges of the box. The IQR is the width of the box.
