Solve for the variable 10/8=n/10

Mathematics
1 answer:
Olin [163]3 years ago
8 0
This exercise is asking you to find the value of n or solve for n, to do so you have to isolate or leave n alone by doing different mathematical operations according to the given equation.

The given equation is \frac{10}{8}= \frac{n}{10}, which is a one step equation meaning that in order to solve for n you have to perform only one mathematical operation, in this case multiplication.

\frac{10}{8}= \frac{n}{10}
n= \frac{25}{2} or 12.5

The value of "n" in this equation is \frac{25}{2} or 12.5.

Find x, and then any unknown angles in the quadrilateral.<br> x= ?
sertanlavr [38]

Answer:

x=65

other angle= 165

Step-by-step explanation:

quadrilaterals always have a total of 360 degrees

because of this you can set up an equation and solve

360=90+40+x+(4x-95)

360=130+5x-95

360=35+5x

325=5x

65=x

plug this in to find missing angle

4(65)-95=165

With the beam being held still at a height of 40 m, the crane breaks and the beam falls to the ground. Assuming no air resistanc
lapo4ka [179]
What we have so far:
Kinetic energy = 0. The reason behind that is because the beam is not moving at a height of 40m.
Gavity, g = 9.8m/s²
Height = 40m
Potential energy = mgh; this is equal to 0 because m, stands for mass and in this problem, we do not have a value for the mass of the beam. Hence, 0 x 9.8m/s² x 40m = 0. Potential energy = 0.

Solution:
We will use the equation of Total energy:
TE = potential energy + kinetic energy

TE = 0 + 0

∴ TE = 0

The answer is: Assuming no air resistance, the total energy of the beam as it hits the ground is 0.

If 18 percent of the beads in a bag are green, 25 percent are red and 40 percent are purple. What is the probablity of choosing
sweet [91]

Answer:

P(G\ then\ R)=0.045

Step-by-step explanation:

From the question we are told that:

Percentage of  Green beads P_g=18

Percentage of  Red beads    P_r=18

Percentage of Purple beads P_p=18

Therefore

Probability of choosing a Green bead is

 P(G)=0.18

Probability of choosing a Red bead is

 P(R)=0.25

Generally the equation for choosing a green bead then a red bead is mathematically given by

Since Outcomes are independent

 P(G\ then\ R)=0.18*0.25

 P(G\ then\ R)=0.045
