Answer:
24 ft
Step-by-step explanation:
The first step is to have uniform units hence we convert the inches to ft.
Conversion
1 inch is equal to 0.0833 ft hence 9 inches will be 9*0.0833=0.75 ft
The shadow of the man is 4.75 ft while actual height is 6ft
By cross multiplication concept, we evaluate that
6ft=4.75 ft shdow
X ft= 19 ft shadow
X=6*19/4.75=24 ft
Therefore, the actual beam height is 24 ft
The slope is -5
To find slope you can use point slope form.
first you use the equation (y-y1)=M(x-x1)
then you change that equation to y=mx+b
The equation is in function form i think thats what its called. Function of H
Answer:
4 people
Step-by-step explanation:
Let's first write an equation.
We want to find the number of tickets t
The total was $49 so our equation will equal $49 and they spent $15 in snacks so on the other side of the eqaution we have to add $15, on the same side as the snacks we need to add in the cost of tickets, which is $8.50 multiplies by t, or the total number of tickets.
$49 = $8.50t + $15
Solve for t, first subtract $15 from both sides.
$49 - $15 = $8.50t
$34 = $8.50t Divide both sides by $8.50
$34/$8.50 = $8.50t/$8.50
$34/$8.50 = t
4 = t
4 tickets meaning 4 people went.
Answer:
7.8 cm and 25.3 cm
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
?² + 7² = 10.5²
?² + 49 = 110.25 ( subtract 49 from both sides )
?² = 61.25 ( take the square root of both sides )
? = ≈ 7.8 cm ( to 1 dec. place )
Then
P = 10.5 + 7 + 7.8 = 25.3 cm
