Mathematics
1 answer:
tatuchka [14]3 years ago
3 0

Step-by-step explanation:

16 kg= 8 hours (divide by 8 to find 1 hour how many kg)

2kg=1 hour ( multiply by 9 as we need to find 18 kg

so 9 hours=18kg

So it'll take 9 hours for 18 kg of dough to be made

Hope this helps!!!

Have a nice day:)

Write an equation of a line (in standard form) that has the same slope as the line 3x-5y=7 and the same y-intercept as the line
Vanyuwa [196]

Answer:

3x-5y=-20

Step-by-step explanation:

We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have two standard form equations which we will get a slope and a y-intercept from. We will convert each to slope intercept form to get the information. We will then write a new slope-intercept equation and convert to standard form.

3x-5y=7 has the same slope as the line. Let's convert.

3x-5y=7\\3x-3x-5y=7-3x\\-5y=7-3x\\\frac{-5y}{-5}=\frac{7-3x}{-5} \\

y=\frac{3}{5}x -\frac{7}{5}

The slope is m=\frac{3}{5}.

2y-9x=8 has the same y-intercept as the line. Let's convert.

2y-9x=8\\2y-9x+9x=8+9x\\2y=8+9x\\\frac{2y}{2}=\frac{8+9x}{2}

y=\frac{8}{2}+\frac{9x}{2}  \\y=4+\frac{9}{2}x

The y-intercept is 4.

We take m=\frac{3}{5} and b=4 and substitute into y=mx+b.

y=\frac{3}{5}x+4

We now convert to standard form.

-\frac{3}{5}x+y=\frac{3}{5}x-\frac{3}{5}x+4\\-\frac{3}{5}x+y=4

For standard form we need the coefficients of x and y to be not zero or fractions. We need integers but the coefficient of x cannot be negative. So we multiply the entire equation by -5 to clear the denominators.

-5(-\frac{3}{5}x+y=4)\\3x-5y=-20

Solve for x. Round to the nearest tenth of a degree, if necessary.
kakasveta [241]

Answer:

x ≈ 52.1°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan x = \frac{opposite}{adjacent} = \frac{KL}{LM} = \frac{36}{28} , then

x = tan^{-1} (\frac{36}{28} ) ≈ 52.1° () to the nearest tenth )

If you multiply two decimals less than 1,can you predict whether the product will be less or greater than either of the factors?

You can predict that it will be less then either of the factors. if you take half of half from anything will you ever have more than half of the original.

AlladinOne [14]

Answer:

4240 inches²

Step-by-step explanation:

In order to find the amount of film needed, we have to find the surface area of this cuboid.

  • Formula to Find Surface Area of Cuboid: 2(wl+hl+hw), where w = width, l = length, and h = height.

Now, let's solve!

  • 2(36*25+20*25+20*36)  
  • 2(900+500+720)
  • 2(2120)
  • 4240

Therefore, the answer is 4240 inches².
