write 1.87 as a fraction.
Answer:
[tex]1\frac{87}{100}[/tex]
Step-by-step explanation:
A decimal is another way of representing a fraction such that the denominator of the fraction is a power of (10).
In the number (1.87), the number goes two places behind the decimal point, which means that the denominator of the fraction is (100), and the numerator is the given number excluding the decimal point.
[tex]\frac{187}{100}[/tex]
Simplify, write as a mixed number,

Answer:
0.542
Step-by-step explanation:
divide the liter by 1000 and get your answer! have a great day
542 liters is approximately equal to 0.542.
Given that a quantity, 542 L we need to convert it into kL,
To convert liters (L) to kiloliters (kL), you need to divide the given value in liters by 1,000 since there are 1,000 liters in 1 kiloliter.
In this case, to convert 542 L to kL, you can use the following formula:
kL = L / 1000
Plugging in the given value:
kL = 542 L / 1000
Dividing 542 by 1000, you get:
kL ≈ 0.542 kL
Therefore, 542 liters is approximately equal to 0.542.

What is the the value of x. Pleaseeeee help I’ll mark you brainlist
Answer:
11.75
Step-by-step explanation:
All angles of a right triangle equal 180°.
So you have to do a substitution method to find the value of x.
Which leaves us with: angle 'A' = 5 × 11.75, angle 'B' = ((3 × 11.75) -4), and angle 'C' = 90. If you add all of them together it is equivalent to 180°.
∴ x = 11.75

14) The slope would still be 9/5
Find the slope-intercept form from the two points (0,8)
and (1, 10).
Answer:
y = 2x + 8
Step-by-step explanation:
We want an equation of the form y = mx + b (slope-intercept).
Look what happens to x as we go from (0, 8) to (1, 10): x increases by 1. This is the 'run' as we calculate the slope.
At the same time, y increases by 2 from 8 to 10.
The slope is defined as m = rise / run, and here is m = 2/1, or m = 2.
Write out y = mx + b and substitute 2 for m: y = 2x + b.
To find the y-intercept, substitute 0 (from (0, 8) ) for x and 8 for y:
8 = 2(0) = b, so b = 8, and the desired equation is
y = 2x + 8

the stove you have to bake in is an old one and only has the temperature in ° Fahrenheit. You are making rusks and have to dry them overnight at a temperature of 176°.Convert this temperature to ° Celsius
Answer:
[tex]80^{\circ} C[/tex]
Step-by-step explanation:
You are making rusks and have to dry them overnight at a temperature of 176° F.
The given temperature is in Fahrenheit. We need to convert it into °C.
The relation between Fahrenheit and °C is given by :
[tex]C=\dfrac{5}{9}(F-32)[/tex]
Put F = 176
So,

if tan27° =k express the following in terms of k
1. sin 27°
Answer:
) ''You need to consider 200^o = 180^o + 20^o , hence you need to use the next formula to evaluate sin 200^o in terms of k:
sin (alpha + beta) = sin alpha*cos beta + sin beta*cos alpha
Plugging alpha = 180^o , beta = 20^o in the formula yields:
sin 200^o = sin (180^o + 20^o) = sin 180^o*cos20^o + sin 20^o*cos 180^o

y = 12000x
Step-by-step explanation:
This function represented in the graph is a linear equation. Since the function passes through the origin (0,0) we can assume that y = mx for some number m.
According to the graph, the function passes through the coordinate (2,24000)
the 2 in the cooridnate represents the x value, and the 24000 represents the y value. Since the function passes through the origin we can find the number m by dividing the y value of the given cooridinate by the x value of the same cooridinate
m = 24000/2
which can be simplified to
m = 12000
Therfore the line on the graph is a representation of y = 12000x
This equation can be used to solve part (c) by plugging in 10 as the x value, this will return, 120,000
NOTE:
The method which was used to find the function only works if the graph passes through the origin.
Uma pesquisa realizada pela IBGE constatou que a população de uma cidade havia aumentado de 82.350 para 105.200 habitantes calcule o valor desse aumento em índices percentuais
Answer:
the value of this increase in percentage indices is 27.77%
Step-by-step explanation:
The computation of the value of this increase in percentage indices is shown below:
Given that
The population has increase from 82,350 to 105,200
So, the increase in percentage would be
= (105,200 - 82,350) ÷ (82,350)
= 22,850 ÷ 82,350
= 27.77%
Hence, the value of this increase in percentage indices is 27.77%
If a stack of 40 nickels fits snugly in the coin wrapper shown, how thick is 1 nickel? Round to the nearest hundredth.
Question:
If a stack of 40 nickels fits snugly in the coin wrapper shown, how thick is 1 nickel? Round to the nearest hundredth.
Coin wrapper volume = 27,480 mm^3
Coin diameter = 21.18 mm
Answer:
The thickness of a coin is: 1.95mm
Step-by-step explanation:
Given
[tex]V = 27480mm^3[/tex] -- volume
[tex]d = 21.88mm[/tex] --- the diameter
Required
The thickness of each coin
This implies that, we calculate the height of each coin.
First, calculate the radius (r) of the coin
[tex]r = \frac{1}{2}d[/tex]
[tex]r = \frac{1}{2} * 21.18mm[/tex]
[tex]r = 10.59mm[/tex]
The volume of the coin is calculated as:
[tex]V =\pi r^2H[/tex]
Where H represents the total heights of the 40 coins
[tex]27480 = 3.14 * 10.58^2 * H[/tex]
Solve for H
[tex]H = \frac{27480 }{ 3.14 * 10.58^2}[/tex]
[tex]H = \frac{27480 }{ 351.480296}[/tex]
[tex]H = 78.1836145944[/tex]
The height of a coin is calculated by dividing H by 40
[tex]h = \frac{78.1836145944}{40}[/tex]
[tex]h = 1.95459036486[/tex]
[tex]h \approx 1.95mm[/tex]
Hence, the thickness of a coin is: 1.95mm

A cube has a surface area of 96 square inches. If 16 cubes are
combined to make a rectangular prism, what is the volume of the
rectangular prism?
Answer:
Step-by-step explanation:
A cube has 6 square faces with equal areas by definition. So a cube with a surface area of 96 units would have the surface area of each side be 96/6 = 16 square units.
Because each face of a cube is a square, it has 4 equal sides. This means that each side of the square is 16/4 = 4 units in length. Since each side of the square face is also an edge of the cube, and the way to calculate the volume of a cube is (length of an edge)^3, this means that the volume of the cube must be 4^3 = 64 cube units.
Volume of Cube = 64 cube units.
The volume of the rectangular prism formed by 16 cubes of each surface area of 96 square inches is 1024 inches³
Volume of a cube
volume of a cube = l³
where
l = side lengthTherefore,
Surface area of a cube = 6l²
Hence,
96 = 6l²
l² = 96 / 6
l = √16
l = 4 inches
Therefore,
volume of each cube = 4³ = 64 inches³
16 cubes forms the rectangular prsim. Therefore,
volume of rectangular prism = 16(64) = 1024 inches³
