Consider, pls, the offered option:
1. knowing points on the graph (2;0;0), (0;5;0) and (0;0;4) it is possible to check an equation.
2. only equation 10x+4y+5z=20 is right if to substitute coordinates in it.

Answer:

Option C is correct.

10x+4y+5z =20

Step-by-step explanation:

The intercept form of the equation of plane is given by:

\frac{x}{a}+\frac{y}{b} +\frac{z}{c} = 1    .....[1]

where

a is the intercept of x-axes

b is the intercept of y-axes and

c is the intercept of z-axes

From the given diagram:

a = 2

b = 5

c = 4

Substitute these in equation [1] we have;

\frac{x}{2}+\frac{y}{5} +\frac{z}{4} = 1

LCM of 2, 5 and 4 is 20

\frac{10x+4y+5z}{20} = 1

Multiply equation 20 both sides we get;

10x+4y+5z =20

Therefore, the equation of plane that contains the given triangle is, 10x+4y+5z =20

1- The answer is that she wants the new time to be 32 minutes

Solution: The question asks that she wants to DECREASE by 20%

What you will do it convert 20% to a decimal (which is 0.20)

Then, you need to multiply the minutes by the decimal:

40 x 0.20 = 8 minutes

Now you know that 8 minutes will be 20% of 40 minutes, so you just subtract 8 from 40 UwU

Together, two people earn $28,000. One earns $2,000 more than the other. How much is the smaller income?
Inessa [10]
Look at this:

2x+$2,000=$28,000
2x=$28,000-$2,000
2x=$26,000
x=26,000 divided by 2
x=$13,000

Which monomials are divisible by 6y^2?
kifflom [539]

Answer:

A) 12y^{3}

Step-by-step explanation:

A) \frac{12y^{3} }{6y^{2} }

=\frac{2y(6y^{2} )}{6y^{2}}

= 2y

B) \frac{24y}{6y^{2} }

=\frac{4}{y}

Hence, 12y^{3} is divisible by 6y^{2} and the correct option is (A).

Jill cuts a piece of cardboard in the shape of a trapezoid.The area of the is 43.5sp cm. If bases are cm and 8.5cm long,what is
boyakko [2]

Answer:

7.25cm

Step-by-step explanation:

Let the complete question be;

<em>Jill cuts a piece of cardboard in the shape of a trapezoid. The area of the is 43.5sp cm. If bases are 3.5cm and 8.5cm long, what is the height.</em>

<em />

Area of a trapezoid = 1/2(a+b)*h

a and b are the parallel sides (bases)

h is the height

Given

a = 3.5cm

b = 8.5cm

A = 43.5 sq.cm

Required

Height h

Substitute the given values into the expression

Area of a trapezoid = 1/2(a+b)*h

43.5 = 1/2(3.5+8.5)*h

43.5 = 1/2 * 12h

43.5 = 6h

h = 43.5/6

h = 7.25cm

Hence the height is 7.25cm
