Answer: 3x + 5 = 57.50
Step-by-step explanation:
Assume that the price of one video game is x. Jamie bought 3 video games so the expression will be:
= 3x
His sister talked him into buying two $1.50 candy bars and a $2.00 drink. The total of this is:
= 1.50 + 1.50 + 2.00
= $5.00
The total amount spent on both the video game and the snacks is $57.50. Equation will therefore be:
3x + 5 = 57.50
A line passes through (-1, 5) and (1, 3)
Answer:
y=-x+4
Step-by-step explanation:
3-5/1-(-1) = -1
(y-(-1)) = -1(x-5)
y+1 = -x+5
y= -x +5-1
y= -x + 4

Answer to part (b)
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.
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
Plugging sin 180^o = 0 and cos180^o = -1 in the formula yields:
sin 200^o = - sin 20^o = -k''

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%
After 2.5 years your investment account has earned $450 in interest. If the interest rate is 7.5% what was the principle on your account?

Last week at the grocery store the price of apples was $1.60. What will the price for 5 1/2 pounds of apples?
Answer: I think the answer is $8.80
Answer:$8.80
Step-by-step explanation: You would take the 1.60 times 5 to get the number 8. Then you would take 1.60 again and times it by 0.5 to get 0.8 or 0.80. And then you would add the 0.8 and the 8 together to get your total of $8.80.
300% of what number is 75?.
Answer:
25
Step-by-step explanation:
Find the number by dividing 75 by 3, since 75 is the number tripled.
75/3
= 25
So, 300% of 25 is 75.
Answer:
25
Step-by-step explanation:
300% * x = 75
300/100 * x = 75
x = 75 * 100/300
x = 25

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.

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,
[tex]C=\dfrac{5}{9}(176-32)\\\\C=\dfrac{5}{9}\times 144\\\\C=80^{\circ} C[/tex]
So, the temperature is equal to [tex]80^{\circ} C[/tex].
A conical termite mound has a height of 1.4m and a base of radius 60cm if there are three termites per cubic centimeter, how many termites inhabit the mound?
Answer:
1583362.7 termites
Step-by-step explanation:
A conical termite mound has a height of 1.4m and a base of radius 60cm if there are three termites per cubic centimeter, how many termites inhabit the mound
The formula for the volume of a cone
= πr²h/3
Radius = r = 60cm
Height = h = 1.4 m
Converting to centimeters.=
1m = 100cm
1.4m = x
x = 1.4 × 100cm = 140 cm
Volume of the cone = π × 60² × 140/3
527787.5658 cm³
From the above question
1cm³ = 3 termites
527787.5658 cm³ = x
Cross Multiply
x = 3 × 527787.5658
x = 1583362.6974 termites
Approximately.= 1583362.7 termites

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
