Answer:

z=28

Step-by-step explanation:

6=1/4z-1

1) take the -1 over to the other side of the equation, so it becomes +1

2) 6+1=7, so your new equation is 7=1/4z

3) to get "z" on its own, you'll have to time the 7 by 4 which is 28

4) your equation is now 28=z and that is your answer.

You can check by inserting 28 instead of z into the equation and it gives you 6. E.G. 1.4 X 28 -1 =6

Answer:

Volume of triangular prism = 126

Volume of composite figure = 462

Step-by-step explanation:

The volume of a triangular prism is base area x height

Here the base of the triangular prism has sides 7(the vertical side) and 6(the horizontal side). The are of this base = area of the triangle = 1/2 * 7 * 6 = 21

(Area of a triangle is 1/2 x b x h where b is base and h is height)

The volume of the prism is simply this area x width = 21 x 6 = 126

To get the composite figure volume add the volume of the rectangular prism so we get 126 + 336 = 462

Answer:

126 cm³

Step-by-step explanation:

The volume of the triangular prism can be calculated using the formula below:

Volume of prism= base area ×height

Area of base

= area of triangle

= ½ ×base ×height

= ½(6)(7)

= 21 cm²

The height of the triangle is the same as the length of the 7cm side of the rectangle.

In this figure, the height of the prism is 6 cm.

Volume of triangular prism

= 21(6)

= 126 cm³

_______

Area of composite figure

= area of rectangular prism +area of triangular prism

= 336 +126

= 462 cm³

Answer:

Median= 10

Step-by-step explanation:

3,5,9,11,19,21

To find the median you put the number in order from least to greatest and then, you cross one off from both sides until you get to the middle.

9+11=20

20/2=10

Answer:

27 units^2

Step-by-step explanation:

The total surface area is calculated by adding all the areas on the surface: the areas of the base, top, and lateral surfaces (sides) of the object. This is done using different area formulas and measured in square units. Volume is the amount of space that a three dimensional object takes up.

So you add, next time you get another question like this

Answer:

1310

Step-by-step explanation:

Because, you have to add the biggest number which is 380, to the second to biggest number which is 360, which will both get you to 740. Then you have to add the 740 to 300 which both gives you 1040 and then last but not least you have to add, 1040 and 270 together which will give you 1310 and that's your answer. :)

i did the quiz

The results of the 100 rolls with the number cube are such that the probability of rolling a 2 is 32%.

This refers to the chances that the number cube rolls a 2 when thrown.

This can be found by the formula:

= Number of times 2 was rolled / Total number of times number cube was rolled

Solving gives:
= 32 / 100

= 32%

Answer:

x=48

y=96

z=36

Step-by-step explanation:

6.4n+3.2n+2.4n=180

n=15

x=3.2(15)=48

y=6.4(15)=96

z=2.4(15)=36

Answer:

130+8n

Step-by-step explanation:

We know that all four humidifiers cost $520 to buy at first. So, we divide that by four to get the cost of one humidifer. $130.

We know that it costs $32 a week to keep all four humidifiers maintained. So, we divide that by four to get the cost of keeping one humidifier maintained. $8 per week.

130+8n is the equation that represents the cost of buying and maintaining one humidifier.

y - -2x - 6 (1)
y = x+15 (2)

From (2) we get x = y-15
We put that in (1) and we get -2(y-15)-6 = y
-2y+30-6 = y
-2y+24=y
-2y+24-y=0
-3y+24 = 0 ==> -3y = -24 ==> y = 8

We put that value in (2) and we get x = 8-15 = -7

Now in order to verify this, we replace the variables and see if (1) = (2)

y = -2x - 6 ==> (-2 * -7) - 6 = 14-6 = 8 (1')
y = x + 15 = -7 + 15 = 8 (2')

(1') = (2') ==> the solution is x = -7 and y = 8

Answer:

x=−2y=2

Step-by-step explanation:

Take the value of x from the first equation:x=2−2y (1)and substitute for x into the second:y=2(2−2y)+6

solve for y ;y=4−4y+6y=105=2

Substitute back into

(1) and find :x=2−4=−2

Answer:

ABD = 140
DBC = 40

Step-by-step explanation:

What is shown is a supplementary angle. These types of angles equal 180 degrees.

So that means whatever angle measures is in the supplementary angle added together would equal 180.

The equation to solve this would be (15x - 4) + (5x - 8) = 180

First, I would combine like terms. The 15x and 5x can be combined together to make 20x and the -4 and -8 would be equal to -12.

The simplified equation is now 20x - 12 = 180.

Next, we need to get rid of the 12. So we add 12 to both sides.

(20x - 12) + 12 leaves 20x by itself

180 + 12 = 192

Our equation is now 20x = 192

Next, we have to make sure that the x is by itself. To do this, we have to divide each side by 20.

20x/20 leaves us with just x.

192/20 is 9.6

x is equal to 9.6

Finally, we plug in the variable's value back into the angle measures to find their value.

15(9.6) - 4 = 140

5(9.6) - 8 = 40

Therefore, ABD is 140 degrees and angle DBC is 40 degrees.

Checking our work:

To check if our work is right, we can add up the angle measures to see if it's equal to 180.

140 + 40 is 180, so we are correct.

I apologize if that was a lot to read, but I hope you understand!
