Answer:

solution given:

volume of lower one[V1]=l×b×h=1.5×0.5×0.5=0.378m³

volume of upper one [V2]=l×b×h=1×0.5×(0.75-0.5)=

0.125m³

total volume=V1+V2=0.378m³+0.125m³=0.503m³

0.503m³ is your answer

What’s the value of the 8 in 281480100

luda_lava [24]

We want to find the value of the 8 in 281,480,100

Let's find the place value of each of the numbers:

2 - hundred millions

8 - ten millions

1 - millions

4 - hundred thousands

8 - ten thousands

0 - thousands

1 - hundreds

0 - tens

0 - ones

I see there are two 8's so I wouldn't be too sure of which value to find, but just in case, we have the chart made above for place values.

There is one 8 at the ten millions value.

There is one 8 at the ten thousands value.

-5x+y=-10 and -4x-y=-26

Bad White [126]

<h2>Answer:</h2>

$\left\{\begin{matrix}x=4\\y=10\\\end{matrix}\right.$

<h2>Step-by-step explanation:</h2><h3>Solve the equation</h3>

$\left\{\begin{matrix}-5x+y=-10\\-4x-y=-26\\\end{matrix}\right.$

_____________________________________

<h3>Add the two equations</h3>

$-5x+y+(-4x-y)=-10+(-26)$

____________________________

<h3>Remove parentheses</h3>

$-5x+y-4x-y=-10-26$

_________________________________________________

<h3>Cancel one variable</h3>

$-5x-4x=-10-26$

___________________________________________

<h3>Combine like terms</h3>

$-9x=-10-26$

______________________________________________

<h3>Calculate the sum or difference</h3>

$-9x=-36$

________________________________________________

Divide both sides of the equation by the coefficient of variable

$x=\frac{-36}{-9}$

____________________________________________________

Determine the sign for multiplication or division

$x=\frac{36}{9}$

_________________________________________

Cross out the common factor

$x=4$

<h3>_____________________________________________</h3><h2>Step-by-step explanation:</h2><h3>Substitute into one of the equations</h3>

$-4\times4-y=-26$

____________________________________________________

Calculate the product or quotient

$-16-y=-26$

______________________________________________________

Rearrange variables to the left side of the equation

$-y=-26+16$

_____________________________________________

Calculate the sum or difference

$-y=-10$

_________________________________________-

Divide both sides of the equation by the coefficient of variable

$y=10$

I dont understand how to do this

tamaranim1 [39]

Answer:

Step-by-step explanation:

AE=2BD

4x+14=2(4x+5)

4x+14=8x+10

8x-4x=14-10

4x=4

x=1

5.2

AB+ED=2FC

AB+36=2×20

AB=40-36=4

next.

m∠J+m∠N=180

6x+5+9x+20=180

15x=155

3x=31

x=\frac{31}{3}

∠N=9x+20=31×3+20=93+20=113

∠M+∠N=180

∠M+113=180

∠M=180-113=67°
