Answer:

x = 2.5

Step-by-step explanation:

Given

[tex]\frac{4}{x}[/tex] = [tex]\frac{12}{7.5}[/tex] = 1.6

Multiply both sides by x

4 = 1.6x ( divide both sides by 1.6 ), hence

x = 2.5

Answer:

I think the answer is 12 rides

Final answer:

After setting up a system of equations with Option A as C = 50 + 2x and Option B as C = 4.5x, we find that after 20 rides, the total costs for both options are the same.

Explanation:

To determine after how many rides the total costs of the two payment options will be the same for the express bus from the center of town, we can set up a system of equations. Option A includes a monthly pass costing $50 plus $2 per ride, and Option B is a flat rate of $4.50 per ride.

Let's define x to be the number of rides. Then for Option A, the cost will be $50 (monthly pass) plus $2 multiplied by x, which can be expressed as the equation C = 50 + 2x. For Option B, the cost is simply $4.50 multiplied by x, which can be written as C = 4.5x.

To find out after how many rides the costs are the same, we set the equations equal to each other: 50 + 2x = 4.5x. Solving for x, we get x = 20. After 20 rides, the total costs for both options A and B will be the same.

The area of a circle when you know the radius is found using the formula Area = PI x r^2

The small circle has a radius of  7 inches.

The area of the small circle is 3.14 x 7^2 = 3.14 x 49 = 153.86 square inches.

Using the circumference of a circle use the formula Area = C^2 / 4*PI

Area of larger circle = 113.097^2 / 4 *3.14 = 12790.93141 / 12.56 = 1018.39 square inches.

Now to find the blue area subtract the area of the smaller circle from the larger one:

1018.39 - 153.86 = 864.53 square inches.

Answer:

[tex]\large\boxed{V=2304\pi}[/tex]

Step-by-step explanation:

The formula of a surface area of a sphere:

[tex]S.A.=4\pi R^2[/tex]

R - radius

We have

[tex]S.A.=576\pi[/tex]

Substitute and solve for R:

[tex]4\pi R^2=576\pi[/tex]         divide both sides by π

[tex]4R^2=576[/tex]          divide both sides by 4

[tex]R^2=144\to R=\sqrt{144}\\\\R=12[/tex]

The formula of a volume of a sphere:

[tex]V+\dfrac{4}{3}\pi R^3[/tex]

Substitute:

[tex]V=\dfrac{4}{3}\pi(12^3)=\dfrac{4}{3}\pi(1728)=(4)\pi(576)=2304\pi[/tex]

Answer:

of the number is X, 16 = 1 + (2/10)×X - 8

Answer:

16 = [tex]\frac{6x}{5}[/tex] - 8

Step-by-step explanation:

Topic: One Unkown equation, mixed numbers

first we have to establish our variables, we only have one so we call

x = "a number"

and we start building our one unknown equation part by part by reading

"Sixteen is the same" means in math that "x ="

"one and two tenths"  1 [tex]^{2/10}[/tex]

this means we have (remember how to sum fractions?)

1 + 2 / 10 = 10/10 + 2/10 = 12/10 = 6/5

so " one and two tenths times a number added to negative 8" become [tex]\frac{6x}{5}[/tex] + (-8)

so we have our equation

16 = [tex]\frac{6x}{5}[/tex]  + (-8) or 16 = [tex]\frac{6x}{5}[/tex]  - 8

[tex]

s=\frac{\Delta{y}}{\Delta{x}}=\frac{-3-0}{-2-0}=\boxed{\frac{3}{2}}

Answer:

x=20

Step-by-step explanation:

you first got to get x by itself so + 19 on each side of the equal signs which gets rid of the -19 on the left side of the equal and it adds 19 on the right side of the equal making the answer x=20

The solution of the equation with a single variable 'n' x – 19 = 1 will be 20.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The equation is given below.

x – 19 = 1

The degree of the equation is one. Then the equation is a linear equation. Simplify the equation, then we have

x – 19 = 1

x = 1 + 19

x = 20

The solution of the equation with a single variable 'n' x – 19 = 1 will be 20.

[tex]m=-\frac{1}{4}-\frac{11}{4}=-3[/tex]

E: [tex]-\frac{5}{4}+m=-\frac{15}{4}[/tex]

[tex]m=-\frac{15}{4}+\frac{5}{4}=-2.5[/tex]

F: [tex]m+2=-0.5[/tex]

[tex]m=-0.5-2=-2.5[/tex]

The equivalent equations are; B,C,E, and F.

Answer:

[tex]m=-\frac{10}{4}[/tex]

[tex]m=-\frac{5}{2}[/tex]

[tex]-\frac{5}{4}+m=-\frac{15}{4}[/tex]

[tex]m+2=-0.5[/tex]

Step-by-step explanation:

Given equation,

[tex]\frac{3}{4}+m=-\frac{7}{4}[/tex]

[tex]\implies m = -\frac{7}{4}-\frac{3}{4}=\frac{-7-3}{4}=-\frac{10}{4}=-\frac{5}{2}[/tex],

Since, [tex]\frac{10}{4}\neq -\frac{5}{2}[/tex]

[tex]\frac{11}{4}+m = -\frac{1}{4}[/tex]

[tex]\implies m = -\frac{1}{4}-\frac{11}{4}=\frac{-1-11}{4}=-\frac{12}{4}=-3\neq -\frac{5}{2}[/tex]

[tex]-\frac{5}{4}+m=-\frac{15}{4}\implies m = -\frac{15}{4}+\frac{5}{4}=\frac{-15+5}{4}=-\frac{10}{4}[/tex]

[tex]m+2=-0.5\implies m = -0.5-2\implies m = -2.5=-\frac{5}{2}[/tex]

Step-by-step explanation:

We are to find out what percentage of 700 is 14.

Assuming [tex] x [/tex] to be the percent of 700 which is 14, we can write it as:

[tex] \frac { x } { 100 } \times 700 = 14 [/tex]

[tex] \frac { x } {100} = \frac {14} {700} [/tex]

[tex] \frac { x } { 1 0 0 } = 0.02 [/tex]

[tex]x=0.02 \times 100[/tex]

[tex]x=2[/tex]

Therefore, 14 is 2% of 700.

Answer:

We can see here that the two sides of both triangle are equal to each other, therefore both triangles are isosceles triangles.

And also the two chords are parallel to each other, which let us know that:

b° = 40°

We also proved that that triangle is an isosceles triangle so:

b° = c° = 40°

Which makes it possible to calculate d°:

b° + c° + d° = 180°

40° + 40° + d° = 180°

d°                    = 180° - 40° - 40°

d°                    = 100°

1.08×10^11

Step-by-step explanation:

1.08 times 10 to the power of 11

The number of pieces of mail in 1995 more than 1965 by = 1.08 * [tex]10^{11}[/tex]

Exponent refers to the number of times a number is used in a multiplication. Power can be defined as a number being multiplied by itself a specific number of times. Exponent is the number to which a number is raised so as to define its power as a whole expression.

In 1995 : 1.8 * [tex]10^{11 }[/tex]

In 1965: 7.2 * [tex]10^{10 }[/tex]

So, the difference will be

= 1.8 * [tex]10^{11 }[/tex]  - 7.2 * [tex]10^{10 }[/tex]

= 1.8 * [tex]10^{10}*10[/tex] - 7.2 * [tex]10^{10 }[/tex]

=18 * [tex]10^{10 }[/tex] - 7.2 * [tex]10^{10 }[/tex]

= (18-7.2)  * [tex]10^{10 }[/tex]

=10.8  * [tex]10^{10 }[/tex]

= 1.08 * [tex]10^{11}[/tex]

Hence, the number of pieces of mail in 1995 more than 1965 by = 1.08 * [tex]10^{11}[/tex]

To find the missing value, divide two consecutive y-values to determine the constant factor. Multiply the last given value by the factor to obtain the missing value.

To find the missing value for the exponential function represented by the given table, we need to observe the pattern of the function.

The given pattern is:

x   -2    -1       0          1           2

y  29  20.3  14.21   6.9629

In this case, we can see that each value of y is obtained by multiplying the previous value by a constant factor.

To determine this factor, we can divide any two consecutive y-values.

For example, dividing 14.21 by 20.3 gives us approximately 0.6988.

So, the missing value can be found by multiplying the last given y-value (6.9629) by this factor.

Hence, the missing value is approximately 4.8616.

The measure of arc CD is 88.8°

In circle geometry , there are certain theorems that guides the solving of problem involving circles.

Some of the theorems are ;

angle at the center is twice angle at the circumference.

The measure of arc is the measure of angle substended at the centre.

Using trigonometric ratio to get the angle at the center.

sinX = 6.35/9.06

sinX = 0.70

X = 44.4°

angle at the centre = 2 × 44.4

= 88.8°

Therefore, arc CD is 88.8°

EXPLANATION

The measure of each interior angle of a regular polygon is given by

[tex] \theta = \frac{(n - 2) \times 180}{n} [/tex]

where n refers to the number of sides of the polygon.

From the question we have n=5 in this case.

We substitute to obtain;

[tex]\theta = \frac{(5 - 2) \times 180}{5} [/tex]

[tex]\theta = \frac{3\times 36}{1} [/tex]

This simplifies to:

[tex]\theta = 108 \degree[/tex]

Hence each interior angles of a regular polygon with 5 - sides is 108°
