Answer:

20%

a) a train goes 60 mph for 180 miles

50 miles

Step-by-step explanation:

6/30=.20 = 20%

180 miles divided by 60 mph=3 hours

80%x = 40 miles

.8x=40

.8x/.8=40/.8

x=50 miles

To shade this on a number line, we can find the point that corresponds to 0.375 and shade it.

It is the representation of numbers in real order.

The difference between the consecutive numbers in a number line is always positive.

We have,

To shade the number line to show 3/5 x 5/8, we can first convert the fractions to decimals:

So,

3/5 = 0.6

5/8 = 0.625

Next,

We can multiply these decimals together to find the product:

= 0.6 x 0.625

= 0.375

To shade this on a number line, we can find the point that corresponds to 0.375 and shade it.

If the number line extends from 0 to 1, with tick marks every 0.1, we can count over 3.75 tick marks from 0 and shade the point that corresponds to that location.

The shaded point should fall between 0.3 and 0.4 on the number line.

Thus,

To shade this on a number line, we can find the point that corresponds to 0.375 and shade it.

Answer:

h = 8.77

Step-by-step explanation:

Isolate the variable, h. Note the equal sign, what you do to one side, you do to the other. Subtract 4.88 from both sides:

h + 4.88 = 13.65

h + 4.88 (-4.88) = 13.65 (-4.88)

h = 13.65 - 4.88

h = 8.77

8.77 is your answer for h.

Hence statement 3 and 5 are true from the equation given in question.

The definition of an equation in algebra is a mathematical statement that proves two mathematical expressions are equal.

Types of Equations:

  Linear Equation: More than one variable may be present in a linear equation. An equation is said to be linear if the maximum power of the variable is consistently 1.

 Quadratic Equation: This equation is of second order. At least one of the variables in a quadratic equation needs to be raised to exponent 2.

   Cubic Equation: A third-order equation is this one. At least one of the variables in cubic equations needs to be raised to exponent 3.

  Rational Equation: A fractional equation having a variable in the numerator, denominator, or both is referred to as a rational equation.

Number of cans used 1/10 part of room  = 1/2

No. of cans paints used 1 part = 1/2 / 1/10 = 5

∵ 1/2 can paint is used = 1/10

∴ 1 can paint used = (1/10)*2 = 1/5

∴ 5 cans  = 100%

3 cans used = (3/5)*100 = 60%

Answer:

a) 7.78 months

b) 1116

Step-by-step explanation:

Given -

[tex]\frac{dP}{dt} = 0.4p-450[/tex]

Integrating the above equation with respect to time, we get -

[tex]\int\ \frac{dP}{0.4p-450} = \int\ dt\\[/tex]

let us define new variable x

[tex]x = 0.4p - 450 \\dx = 0.4 dy[/tex]

substituting these values in above integral equation, we get -

[tex]\frac{1}{0.4} \int\ \frac{dx}{x} = \int\ dt\\ln x = 0.4 t + C\\x = ce^{0.4t}[/tex]

[tex]P (t) = \frac{C}{0.4} e^{0.4t} +1125\\[/tex]

at t = 0, P (0) = 1075, using this condition, we get -

[tex]\frac{c}{0.4} = -50\\P(t) = 50 e^{0.4t} +1125 \\t = 7.78\\P(0) = 1125 - \frac{1125}{e^{4.8}} = 1116[/tex]
