Leslie paid $12 for 4 books. What is the unit rate of the book purchase?

Answer:

17

Step-by-step explanation:

As we know that when diagonals bisect each other it gets divided into two equal parts so

CG = CE

6z - 85 = z

6z - z = 85

5z = 85

z = 85 / 5

Therefore z = 17

Hope it will help :)

Answer:

[tex]\displaystyle 17[/tex]

Step-by-step explanation:

[tex]\displaystyle 6z - 85 = z → 85 = 5z; 17 = z[/tex]

Question does not specify how many year and is in plural form considering the level of question I will consider it is some typo error and is just 1 year

Step 1

Finding Intrest for Rs200

We have

Principal(P) = Rs 200

Rate (R) = 7%pa

Time (T) = 1year

Intrest(I) =?

We have ,

I =PTR/100

=200*7/100

=Rs 14

Step 2

Finding intrest for Rs2000

Given

Principal(P)=Rs2000

Rate(R) =11%

Time(T) =1 year

Intrest(I) =?

We know,

I =PTR/100

=2000*11/100

= 20*11

=Rs 220

Answer:

x = 2.411

Step-by-step explanation:

6400 = (8) (2^(4x))

Divide both sides by 8 to get;

6400/8 = (2^(4x))

800 = (2^(4x))

Using logarithms, we can solve as;

Log 800 = 4xLog 2

4x = Log800/Log2

4x = 2.9031/0.3010

4x = 9.6449

x = 9.6449/4

x ≈ 2.411

Trigonometric Ratios

The ratios of the sides of a right triangle are called trigonometric ratios.

The longest side of the triangle is called the hypotenuse and the other two sides are the legs.

The sine ratio relates the opposite side of an angle of the triangle with the hypotenuse:

[tex]\displaystyle \sin B=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]

Here, the opposite leg to angle B is the side CA=2, and the hypotenuse is the side AB=3, thus:

[tex]\displaystyle \sin \angle B=\frac{2}{3}=0.667[/tex]

Calculating the inverse sine function:

[tex]\angle B=\arcsin (0.667)[/tex]

[tex]\boxed{\angle B=41.81^\circ}[/tex]

Answer:

-1

Step-by-step explanation:

The value of the function when domain y = 30 is f ( 30 ) = -1

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = 14 - ( 0.5 )x   be equation (1)

Now , when the domain of the function x = 30 , we get

f ( 30 ) = 14 - ( 0.5 ) ( 30 )

f ( 30 ) = 14 - 15

On further simplification , we get

f ( 30 ) = -1

Hence , the function is f ( 30 ) = -1

Dont worry i checked my answer two times :)

0.03

Step-by-step explanation:

S ∝ t, introduce constant, if value of S depends on t only. Let that constant be 'k'.

=> S = kt

When, S = 0.6 & t = 4:

Answer

=> 0.6 = k(4)

=> 0.6/4 = k

=> 0.15 = k

Therefore, when t = 0.2

=> S = kt

= (0.15)(0.2)

= 0.03

Answer:

1800ml of water= 800 ml of car shampoo

1 ml of water = 800/1800 ml of car shampoo

360 ml of water = 800/1800 * 360 ml of car shampoo

= 160 ml of car solution

Answer:

13 buses

Step-by-step explanation:

There are 579 students and each bus carries 48 students so:

579 ÷ 48 = 12.1

Now you could say that only 12 buses are needed but there would be an extra student remaining so you need 13 buses.

Answer:

y = -2.5x + 2.5

Step-by-step explanation:

Put the equation into y = mx + b form by isolating y:

2x - 5y - 10 = 0

2x - 5y = 10

-5y = -2x + 10

y = 2/5x - 2

Perpendicular lines have opposite reciprocal slopes, so the line's slope will be -5/2, or -2.5

Plug in the slope and given point into y = mx + b, and solve for b:

y = mx + b

5 = -2.5(-1) + b

5 = 2.5 + b

2.5 = b

Plug in the slope and y intercept:

y = mx + b

y = -2.5x + 2.5 is the equation of the perpendicular line
