Answer:
Solution given:
y=25 [base side of isosceles triangle]
sin 45=opposite/hypotenuse
sin45=25/x
x=25/sin45
x=25√2
Answer: 616
Explanation:
When finding the volume of an object use: LxWxH
L=14
W=11
H=4
Now multiply 14x11x4=616

Answer:
5.2 seconds
Step-by-step explanation:
We want to determine the value of x when h(x) = 0
:
-16x^2 +83x + 4 = 0
:
use quadratic formula to determine the value for x
:
x = ( -83 + sqrt(83^2 - 4*(-16)*4) ) / (2*(-16) = −0.047753182
:
x = ( -83 - sqrt(83^2 - 4*(-16)*4) ) / (2*(-16) = 5.235253182
:
we want the positive value for x since time runs forward
:
the ball hung in the air for approx 5.2 seconds
Answer:
-7
Step-by-step explanation:
-2(x+5)=4
open the bracket with -2
-2x - 10 = 4
combine the like terms
-2x = 4 + 10
-2x = 14
divide by -2
-2x/-2 = 14/-2
x = -7
Answer:
There are 8 adults in the group.
Step-by-step explanation:
Let the number of adults in the group be 'x'.
Given:
Number of children = 1
Number of adults = 'x'
Cost for a ticket of adult = $9
Cost for a ticket of a child = $6
Total cost = $78
Total cost is equal to total cost of tickets of 'x' adults plus cost of ticket of 1 child.
Unit cost of 1 adult × Number of adults + cost of ticket of 1 child = Total cost
Framing in equation form, we get:
<u><em>Adding -6 on both sides, we get:</em></u>
<u><em>Dividing both sides by 9, we get:</em></u>
Therefore, there are 8 adults in the group.
