Answer:
Step-by-step explanation:
solution 1 :
adult : 7 - x
child : x
total spend : 54.50 = (7 - x) * 9.5 + x * 6.5
we solve : 54.50 = 66.5 - 3x , x = 4
solution 1 :
adult : y
child : x
x + y = 7.......(1)
total spend : 54.50 = y * 9.5 + x * 6.5........(2)
we solve : x= 4 , y = 3
The first option is the right one.
You have to find the greates common divisor of the coefficientes, which is -6 and then divide each momomial with lead to: -6 (m^2 + -3m + 6).
You can verifiy the result by multiplying -6 times the polynomial inside the parenthesis, using the distributive property.
Answer:
QR = 82.38 to nearest hundredth.
Step-by-step explanation:
As they are similar corresponding sides are in the same ratio.
So MN / QR = LM / QR
13/51 = 21/ QR
`3QR = 51*21
QR = 51*21/13
QR = 82.38
Answer:
The perimeter of the Rhombus is 100 cm
Step-by-step explanation:
First of all, we will need to find the length of the other diagonal.
let’s call the diagonals p and q
Mathematically, the area of the Rhombus is;
pq/2 = Area of Rhombus.
Let’s call the missing diagonal p
So;
(p * 14)/2 = 336
14p = 672
p = 672/14
p = 48 cm
Now, we can find the perimeter of the Rhombus using these diagonals.
Mathematically;
P = 2 √(p^2 + q^2)
Substituting these values, we have;
P = 2 √(14)^2 + (48^2)
P = 2 √(2500)
P = 2 * 50
P = 100 cm
<h2>Time Interval : 1 sec to 1.414 sec</h2>
Step-by-step explanation:
The height of the stuntperson jumping off a is modelled as . Here is the time in seconds.
We have to record the person when he is between the heights from the ground.
When ,
When ,
The stuntperson is at height at , and is at height at .
∴ The camera should film the person for the time interval .
