Answer:

The price of one gallon of gasoline is $3.15

Step-by-step explanation:

If the lady buys 2.4 gallons of gasoline for a total of $7.56, then as the problem suggests, one can find the unknown price of gasoline per gallon (p) by solving the equation for the unknown "p":

2.4  p = 7.56

then divide both sides by 2.4 to isolate the unknown "" on one side of the equal sign:

p = 7.56/2.4

p = $3.15

so this is the price per gallon of gasoline.

Answer:

2 students are in both clubs

Step-by-step explanation:

x = 1 student (this number may be more than the total because one student can be in 2 clubs)

Club a = 13

Club b = 20

13 + 20 = 27x

Total members of clubs - total number of students = 27x - 25 = 2

2 students are in both clubs

Answer:

Therefore the zeros of this function are between 1 and 2. So the correct answer is "a".

Step-by-step explanation:

In order to find the zeros of a function we need to find at which values for "x" make f(x) equal to zero. Therefore we have:

[tex]f(x) = x^3 - 2 \\0 = x^3 - 2\\x^3 - 2 = 0\\x^3 = 2\\x = \sqrt[3]{2} = 1.2599[/tex]

Therefore the zeros of this function are between 1 and 2. So the correct answer is "a".

Answer:

y = [tex]-\frac{7}{8}[/tex]x + 4

Step-by-step explanation:

-32 = -7x - 8y

Slope-intercept: y=mx+b

First, we can add 8y on both sides so we can get u by itself.

8y - 32 = -7x

Now, we can add 32 to both sides.

8y = -7x + 32

Now, we divide 8 on both sides of the equation so we can get y by itself just like in the slope-intercept formula.

y = [tex]\frac{-7}{8}[/tex]x + [tex]\frac{32}{8}[/tex]

Lastly, we can simplify and you will have your answer.

y = [tex]-\frac{7}{8}[/tex]x + 4

Therefore, B

Answer:

The answer is b

Step-by-step explanation:

When there is only 2 squares it wil be 2(4) (for 2 squares) and then 2(2) for the single square lw

So adding in another square will make it 2(6)+2(2)

=16 chairs

Answer:

x =5

y = 35

Step-by-step explanation:

y = 7x

y = 3x+20

Since they both equal y, we can set them equal to each other

7x = 3x+20

Subtract 3x from each side

7x-3x = 3x+20-3x

4x= 20

Divide each side by 4

4x/4 =20/4

x = 5

Now find y

y = 7x

y = 7(5)

y = 35

Answer:

The Quantity of heat require is [tex]0.062kJ[/tex]

Step-by-step explanation:

This problem bothers on the topic of heat capacity.

Given data

mass of water m=  [tex]710 grams[/tex]

converting from grams to kg we have =[tex]\frac{710}{1000} = 0.71kg[/tex]

initial temperature T1= 4°C

final temperature T2= 25°C

heat capacity of water = [tex]4.184 J/g[/tex]

The expression for the quantity of heat required is given has

[tex]Q= mc(T2-T1)[/tex]

substituting our given data we have

[tex]Q= 0.71*4.184*(25-4)\\Q= 2.97*(21)\\Q= 62.38J\\[/tex]

In kilograms we have to divide by [tex]1000[/tex]

[tex]Q= \frac{62.38}{1000} = 0.062kJ[/tex]

Answer:

  (d)  528 ft³

Step-by-step explanation:

The shape is that of a trapezoidal prism. The front face is a trapezoid with bases 8 ft and 14 ft, and height 6 ft. Its area is ...

  A = (1/2)(b1 +b2)h = (1/2)(8 +14)(6) = 66 . . . . square feet

Then the volume is given by ...

  V = Bh

where B is the area of the (trapezoidal) base, and h is the height of the prism (8 ft). Filling in the values, we find ...

  V = (66 ft²)(8 ft) = 528 ft³

The pool can hold 528 ft³ of water.

Answer:

The missing side = 30 cm

Step-by-step explanation:

Pythagorean Theorem

a^2 + b^2 = c^2

40^2 + b^2 = 50^2

1600 + b^2 = 2500

-1600             -1600

b^2=900

square root of both sides

b=30 cm

Answer:

Step-by-step explanation:

Velocity is the speed of an object in a definite direction. In mechanics, velocity is a vector quantity. It requires magnitude and direction to make any sense. Velocities are expressed per unit time.

The SI unit of time is the second.

Now, suppose we need the velocity in feet per second. A simple calculation will help:

feet per second = miles per hour × 1.466667 [ in other words, one mile per hour equals 1.466667 feet per second]

For a space capsule moving at 80 miles per hour, the velocity is given by

                          = 100 × 1.466667

                          = 146.67 ft/s [feet per second]

Answer:

AB = 4.9 ft

Step-by-step explanation:

Here, we are to calculate the length of AB.

Firstly, please check the diagram of the triangle we have in the attachment.

From there we can see that what we are asked to calculate is the length of the hypotenuse(AB) while what we have is the length of the opposite and the angle.

Mathematically, when we have the opposite and the hypotenuse, the trigonometric ratio that links both is the sine

sine = opposite/hypotenuse

Sin 47 = 3.5/hypotenuse

hypotenuse = 3.5/sin 47

hypotenuse = 4.7856

To the nearest tenth of a foot AB = 4.8 ft

Answer:

Step-by-step explanation:

The diagram representing the trapezoid is shown in the attached photo. The median EF is a line segment that is half way between the 2 bases. The length of the median is the average of the two bases. Therefore,

EF = (12 + 18)/2 = 15

Two similar trapezoids are formed. They are ABFE and EFCD

By comparing both trapezoids, it means that

4/15 = FC/18

Cross multiplying, it becomes

4 × 18 = 15FC

72 = 15FC

FC = 72/15

FC = 4.8

Answer:

The area of trapezoid is 36 [tex]m^2[/tex].

Step-by-step explanation:

To find the area of a trapezoid, you need this formula:

[tex]A = \frac{(a+b)}{2} \times h[/tex]

[tex]a =[/tex] long base

[tex]b =[/tex]short base

[tex]h =[/tex] altitude (height)

-Use the following measures of trapezoid for the formula:

[tex]A = \frac{(8+4)}{2} \times 6[/tex]

-Then, you solve the formula:

[tex]A = \frac{(8+4)}{2} \times 6[/tex]

[tex]A = \frac{12}{2} \times 6[/tex]

[tex]A = 6 \times 6[/tex]

[tex]A = 36[/tex]

So, therefore, the area of a trapezoid is 36 [tex]m^2[/tex].

Step-by-step explanation:

Answer:

[tex] log_{2}(9x) - log_{2}(3) = 3 \\ 3 = log_{2}(8) or log_{2}( {2}^{3} ) \\ log_{2}( \frac{9x}{3} ) = log_{2}(8) \\ \frac{9x}{3} = 8 \\ 9x = 8 \times 3 \\ 9x = 24 \\ x = \frac{24}{9} \\ x = \frac{8}{3} \\ x = 2 \times \frac{2}{3} [/tex]

Answer:

[tex]\log _2\left(9x\right)-\log _2\left(3\right)=3 : x = \frac{8}{3}[/tex]

Decimal:

[tex]x = 2.66666...[/tex]

Step-by-step explanation:

[tex]\log _2\left(9x\right)-\log _2\left(3\right)=3[/tex]

Add [tex]log _2\left(3)[/tex] to both sides:

[tex]\log _2\left(9x\right)-\log _2\left(3\right)+\log _2\left(3\right)=3+\log _2\left(3\right)[/tex]

Simplify:

[tex]\log _2\left(9x\right)=3+\log _2\left(3\right)[/tex]

Use the logarithmic definition: If [tex]\log _a\left(b\right)=c\:\mathrm{then}\:b=a^c[/tex]

[tex]\log _2\left(9x\right)=3+\log _2\left(3\right)\quad \Rightarrow \quad \:9x=2^{3+\log _2\left(3\right)}[/tex]

[tex]9x=2^{3+\log _2\left(3\right)}[/tex]

Expand [tex]2^{3+\log _2\left(3\right)} : 24[/tex]

[tex]9x=24[/tex]

Solve: [tex]9x=24 : x = \frac{8}{3}[/tex]

[tex]x = \frac{8}{3}[/tex]

Verify solutions: [tex]x = \frac{8}{3}[/tex]  : True

The solution is:

[tex]x=\frac{8}{3}[/tex]

Step-by-step explanation:

Given f(x)=x^2, after performing the following transformations: shift upward 74 units and shift 39 units to the right, the new function g(x) = (x -39)^2 +74

In mathematics, a transformation is a feature f, typically with a few geometrical underpinnings, that maps a fixed X to itself, i.e. f: X → X.
