What is the equivalent expression for 4(8x-5)

Answer: 21 miles

Step-by-step explanation:

Here's the remainder of the question:

Write an equation to determine the distance in miles x between the airport and Ann's home.

We are informed that the taxi fare was $2.10 per mile, and she gave the driver a tip of $5 Ann paid a total of $49.10, this can be expressed into an equation as:

(2.10 × x) + 5 = 49.10

2.10x + 5 = 49.10

2.10x = 49.10 - 5

2.10x = 44.10

x = 44.10 / 2.10

x = 21

The distance between the airport and Ann's home is 21 miles.

Remember that a dime is worth 10 cents and a quarter is worth 25 cents and $4.60 is 460 cents.

Let D = the number of dimes and Q = the number of quarters.

Now let's translate the English into math. . .

there are 28 coins in all--> D + Q = 28  so D = 28 - Q

they are worth 460 cents--> 10D + 25Q = 460

Now substitute 28-Q for D--> 10(28-Q) + 25Q = 460

280 - 10Q + 25Q = 460

Combine like term. . .

15Q = 180

Divide both sides by 15--> Q = 12

So D = 16

Answer:

12

Step-by-step explanation:

D=dimes Q=quarters

D+Q=28 so D=28-Q

460=10D+25Q

substitute 28Q for D

10(28-Q)+25Q=460

280-10Q+25Q=460

combine like terms

15Q=180

divide both sides by 15 so Q= 12 and D=16

(I believe this is the correct answer)

Answer:

960

Step-by-step explanation:

1200 is the total price that she sold it for, that is the 100%

the 20% of 1200 is 240

so 1200-240 = 960

Given:

The percent value is 0.034%.

To find:

The decimal value of the given percent.

Solution:

We know that,

[tex]x\%=\dfrac{x}{100}[/tex]

Using the above rule, 0.034% can be written as

[tex]0.034\%=\dfrac{0.034}{100}[/tex]

[tex]0.034\%=0.00034[/tex]

Therefore, the decimal form of given percent value 0.034% is 0.00034.

Step-by-step explanation:

The quadrant in which the angle θ lies when sin θ > 0 and cos θ < 0 will be

in the second quadrant

What are trigonometric relations?

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

In the first quadrant, sin, cos and tan are all positive.

In the second quadrant going anti-clockwise, only sin is positive.

In the third quadrant going anti-clockwise, only tan is positive.

In the fourth quadrant going anti-clockwise, only cos is positive

Given data ,

Let the angle be θ

Now , the sin of the angle θ is positive and cos of the angle θ is negative

The equation is given as

sin θ > 0 and cos θ < 0

And , from the trigonometric relations , we know that

In the first quadrant, sin, cos and tan are all positive.

In the second quadrant going anti-clockwise, only sin is positive.

In the third quadrant going anti-clockwise, only tan is positive.

In the fourth quadrant going anti-clockwise, only cos is positive

So , in the second quadrant only sin is positive and all the other trigonometric relations are negative

Therefore , the quadrant where sin θ > 0 and cos θ < 0 will be in the second quadrant

Hence , The quadrant in which the angle θ lies when sin θ > 0 and

cos θ < 0 will be in the second quadrant

Answer:

Pls send a more clearer picture

Step-by-step explanation:

Answer:

141

Step-by-step explanation:

First, you would round 72.91 to 73 because the number to the right of 7 is greater than or equal to 5, so you would round up. Same goes for 67.526. round both up to 73 and 68 then add. You would get an answer of 141 :)

Answer: 141

Step-by-step explanation: By rounding up to the nearest whole number, that is taking 72.91 -> 73. The reason it is this way is that when a decimal is past 0.5, you round up. If a decmial is below 0.5, then you round down.

In this specific situation, we get the numbers 72.91 and 67.526.

As I explained, the numbers would round up because both numbers decimal values are above 0.5.

So after 72.91 is 73, and after 67.526 is 68.

68 + 73 =

141

Answer:

4) 120π cm^2

5) 56π cm^2

6) 32π cm^2

Step-by-step explanation:

Surface Area of Cylinder = 2π[tex]r^{2}[/tex] + (2πr)(height)

(will use variable h for height)

4)

diameter = 8 cm

r = 0.5(diameter) = 0.5(8) = 4 cm

height = 11 cm

2π[tex]4^{2}[/tex] + (2π)(4)(11)

= 2π(16) + 2π(44)

= 32π + 88π

= 120π cm^2

5)

diameter = 8 cm

r = 0.5(diameter) = 0.5(8) = 4 cm

height = 6 cm

2π[tex]4^{2}[/tex] + (2π)(4)(6)

= 2π(16) + 2π(12)

= 32π + 24π

= 56π cm^2

6)

diameter = 6 cm

r = 0.5(diameter) = 0.5(6) = 3 cm

height = 7 cm

2π[tex]3^{2}[/tex] + (2π)(3)(7)

= 2π(9) + 2π(7)

= 18π + 14π

= 32π cm^2

Answer:

83

Step-by-step explanation:

f(x)= -3(-25)+8=83

The value of the variable is "x = 11" when f(x) = -25 for the given function f(x) = -3x+8.

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

To determine x when f(x) = -25 for the function f(x) = -3x+8, you will need to solve the equation -3x+8 = -25 for x.

To do this, you can follow these steps:

Begin by isolating the x term on one side of the equation. To do this, you can add 3x to both sides of the equation to get -3x+3x+8 = -25+3x.

Simplify the left side of the equation by combining like terms to get 8 = -25+3x.

Subtract 8 from both sides of the equation to get 0 = -25+3x - 8.

Add 25 to both sides of the equation to get 33 = 3x.

Divide both sides of the equation by 3 to get x = 33/3 = 11.

Therefore, x = 11 when f(x) = -25 for the function f(x) = -3x+8.
