Answer:

A and B.

Step-by-step explanation:

To find the area, you need to multiply the length and width.

A = L x W

5 x 4 = 20

10 x 2 = 20

Answer:

Considerations:

[tex]$y=-(x) \left \{ {{\text{if } x<0\text{ then }y>0} \atop {{\text{if } x> 0\text{ then }y<0}} \right. $[/tex]

[tex]$y=x\left \{ {{\text{if } x<0\text{ then }y<0} \atop {{\text{if } x> 0\text{ then }y>0}} \right. $[/tex]

Also,

[tex]$-\frac{a}{b}=\frac{-a}{b}=\frac{a}{-b}, b\neq0 $[/tex]

A positive number divided by a positive number results in a positive quotient, and its opposite is always negative.

The fraction [tex]$\frac{5}{-12} $[/tex]  can be described as a positive number divided by a negative number, which always result in a negative quotient.

The fractions have same value, so Liam is correct.

the answer is C, I think because parallel lines never touch

The required answer is two lines are parallel if and only if they lie in the same plane and do not intersect, and two lines are perpendicular if and only if they lie in the same plane and intersect at the right angles. Option   A is correct.

Given that,
An incomplete statement is given,
We have to complete the statement using the appropriate options that thinks fit to black space.

The line is a curve showing the shortest distance between 2 points.

Here,
Two lines are ___ if and only if they lie in the same plane and do not intersect.
The above statement is the definition of parallel lines, so the complete statement is,
Two lines are parallel if and only if they lie in the same plane and do not intersect.,

Two lines are __ if and only if they lie in the same plane and intersect at the right angles

The above statement is the definition of perpendicular,
So the complete statement is,
Two lines are perpendicular if and only if they lie in the same plane and intersect at the right angles.

Thus, the required correct option is option A, Parallel and perpendicular.

Some number times itself is 25. The question is: which number?

That would be 5 since 5 times 5 = 25

You can also apply the square root to 25 to get 5, to avoid guessing and checking.

Answer:

hope this helps!

Step-by-step explanation:

The inverse function of the given function will be f(x)⁻¹ = ( 10 ) / ( 9x - 99).

A function is defined as the expression that set up the relationship between the dependent variable and the independent variable. In an inverse function, the value of two variables x and y are interchanged, and then the value of y is given an inverse function.

Given function is f(x) = ( 10/9x) + 11. the inverse function will be calculated as below:-

y = 10/9x+11

x = ( 10 / 9y ) + 11

x - 11 = ( 10 / 9y )

9y / 10 = ( 1 / ( x - 11 )

9y = 10 / ( x - 11 )

y = ( 10 ) / ( 9x - 99 )

Therefore, the inverse function of the given function will be f(x)⁻¹ = ( 10 ) / ( 9x - 99).

The value of x is 11.037

The correct option is (B)

Trigonometry is a branch of mathematics that studies relationships between the sides and angles of triangles.

Using Trigonometry,

cos 25 = B/ H

cos 25 = 10 / x

0.906 = 10/ x

x= 10/ 0.906

x= 11.037

The efficiency of the car in unit miles per gallon will be 26.28.

To convert any unit into another is called a unit conversion.

In order to convert units, we need to care about their dimensions their dimension should not be changed.

Given that,

The car takes 9 liters per 100​ kilometers

9 liters ⇒ 100 km

Since 1 gal= 3.7854 L → 1 L = (1/3.7854) gal

9 L = (9/3.7854) gal

1 mile = 1.6 km → 1 km = (1/1.6) miles

100 km = (100/1.6) miles

So, (9/3.7854) gal ⇒ (100/1.6) miles

Efficiency = (100/1.6) ÷ (9/3.7854)

Efficiency = 26.28 miles/gal

Hence "The efficiency of the car in unit miles per gallon will be 26.28".

Answer:

79.95

Step-by-step explanation:

The first step is to rewrite the percentages into decimals so they can be added or subtracted easier. To turn a percentage into a decimal, remove the percent sign and move the decimal two spaces to the left (in other words, divide the number by 100).

12% becomes -0.12

8% becomes 0.08

Now, let's solve.

79.99 - 0.12 + 0.08

Evaluating 79.99 - 0.12, the equation becomes 79.87 + 0.08.

Evaluating 79.87 + 0.08, we get the final answer, 79.95.

Answer:

The answer is 2√15 .

Step-by-step explanation:

Using Indices Law :

[tex] \sqrt{a} \times \sqrt{b} = \sqrt{ab} [/tex]

[tex] \sqrt{ - 6} \times \sqrt{ - 10} [/tex]

[tex] = \sqrt{ - 6 \times - 10} [/tex]

[tex] = \sqrt{60} [/tex]

Next, you have to find the common factors of 60 :

60 = 1×60

60 = 2×30

60 = 3×20

60 = 4×15

60 = 5×12

60 = 6×10

In order to simplify, we have to choose a perfect square from the factors above. In the factors above, 4 is a perfect square so that we can square root it :

[tex] \sqrt{60} [/tex]

[tex] = \sqrt{4 \times 15} [/tex]

[tex] = \sqrt{4} \times \sqrt{15} [/tex]

[tex] = 2 \times \sqrt{15} [/tex]

[tex] = 2 \sqrt{15} [/tex]

To express [tex]8^{1/2[/tex]in simplest radical form, recognize that it's equivalent to the square root of 8, then simplify to 2√2 by breaking down 8 into prime factors and finding pairs of factors.

Explanation:

To express [tex]8^{1/2[/tex] in simplest radical form, we follow these steps:

Recognize that an exponent of 1/2 is equivalent to the square root.

Find the square root of 8, which can also be written as √8.

Since 8 is not a perfect square, we can simplify it by breaking it down into its prime factors: 8 = 2 x 2 x 2.

Group the factors into pairs to determine the square root: 8 has one pair of 2s.

This pair comes out of the radical as a single 2, leaving one 2 inside the radical: 2√2.

Therefore, 8^1/2 simplifies to 2√2, which is the simplest radical form.

Answer: $13 for the 9 mile ride.

The taxi ride that is m miles long would cost as follows: 4 + m

Step-by-step explanation:

The cost of Joseph's taxi ride is calculated by adding a flat fee of $4 to $1 for each mile driven. Thus, a 9-mile ride would cost $13. For a ride of m miles, the cost would be $4 plus $1 per mile.

The cost of a taxi ride can be determined using a function that considers two components: a flat fee, and a rate per mile. In Joseph's case, the online tax service charges a $4 flat fee for pickup, and $1 per each mile driven. Hence, the equation for the cost of a taxi ride (C) for Joseph is as follows: C= 4+1*m.

For a ride of 9 miles, we would substitute m with 9: C = 4+ 1*9, which simplifies to C = $13. Therefore, a 9-mile ride would cost $13.

For a taxi ride that is m miles long, the cost would be C = 4 + 1*m. The 4 represents the flat fee, and the 1*m represents the cost per mile that is driven multiplied by the number of miles in the ride. Therefore, a taxi ride that is m miles long would cost $4 plus $1 per mile.
