The value of x in degrees will be  x=78.46

The branch of mathematics dealing with the relations of the sides and angles of triangles and with the relevant functions of any angles.There are different angles like Cos,Sin,tan,cosec,sec and cot in the trigonometry.

It is given that:

We have the value of CosX=0.2 we will take inverse of the value 0.2 and find the angle X. after taking the cos inverse of the value 0.2 we found out the angle X=78.46

Cos X   =     0.2

X      =    Cos¹ 0.2

X      =     78.46°

Hence the value of x in degrees will be x=78.46

Answer:

If the slope is 7/4x : y=-4/7x-6/7

Step-by-step explanation:

1) Find reciprocal of slope: 7/4 becomes -4/7

2) insert into equation y=mx+b: y=-4/7x+b

3) solve for "b" by substituting x and y with the point (2,-2): -2=-4/7(2)+b

b=-6/7

4) write final equation: y=-4/7x-6/7

Step-by-step explanation:

in its basic structure such a prism is like a cube (just rectangular and not squared) : 6 sides (rectangles).

2 rectangles top and bottom 6×8 = 48 m²

48 × 2 = 96 m²

2 rectangles front and back 6×4 = 24 m²

24 × 2 = 48 m²

2 rectangles left and right 8×4 = 32 m²

32 × 2 = 64 m²

the total surface area is

96 + 48 + 64 = 208 m²

it is hard to find other integer dimensions for the same surface area.

but as long as we are not restricted to integer numbers :

let's cut e.g. the height in half.

and we get

2 rectangles left and right 8×2 = 16 m²

16 × 2 = 32 m²

that "nails" already 2 dimensions (width and height).

we need to set now the third dimension (length) to create the same surface area :

length×8×2 + length×2×2 = 208 - 32 = 176

20×length = 176

length = 8.8 m

so, with

length = 8.8 m

width = 8 m

height = 2 m

we still get

2 rectangles top and bottom 8.8×8 = 70.4 m²

70.4 × 2 = 140.8 m²

2 rectangles front and back 8.8×2 = 17.6 m²

17.6 × 2 = 35.2 m²

2 rectangles left and right 8×2 = 16 m²

16 × 2 = 32 m²

as total surface area

140.8 + 35.2 + 32 = 208 m²

answer is B, 9 units

Step-by-step explanation:

Answer:

C) 15.5 units

Step-by-step explanation:

Step-by-step explanation:

If we let the length of the base be b, then the height is 2b-9.

This means that (1/2)(b)(2b-9)=9

b(2b-9) = 18

2b^2 - 9b = 18

2b^2 - 9b - 18 = 0

(2b+3)(b-6)=0

b = -3/2 or b= 6 (disregard b = -3/2 as distance is positive)

This means b =6, and thus the height is 2(6)-9=3.

Value of 20

Answer:

They would be paying $189

The amount of money that the customer paying for 7,000 pieces is $189.

An equation is an expression that shows the relationship between two or more variables or numbers.

Number of bags for 7000 pieces = 7000/500 = 14

Cost for 7000 pieces = $0.03 * 7000 = $210

Discount = 210 - (0.1 * 210) = $189

The amount of money that the customer paying for 7,000 pieces is $189.

Answer

great common factor of 14 and 21 is 15. so your answer is 15

Part A: The x-intercept represents the maximum amount of profit the company makes depending on the price of erasers. The intervals would be the prices of the erasers, and they represent the correlation between sale and profit. For example, when each eraser costs $4, the company makes the max profit of $270.

Part B: The average rate of change would be $91.875 and the rate represents that, on average, for each dollar that the price of the eraser jumps, the profit jumps an average of $91.875.

Part C: The constraints of the domain would be things like how the price of the erasers cannot go less than $0 or above $8; 0 [tex]\leq[/tex] x [tex]\leq[/tex] 8.

Answer:

-5/12 , -1/2 ,-7/12

Step-by-step explanation:

a = -1/3

b= -2/3

n = 5

d = b- a/n+1

d= (-2/3 + 1/3)/(5+1)

d = -1/12

numbers are :

-1/3 , -1/3-1/12 , -1/3-2/12 , -1/3-3/12, -2/3

-1/3,-5/12,-1/2,-7/12,-2/3

The number of eight-digit codes could she make using the digits in her birthday is 1120 digits

Since the order of the arrangement of the digits matter, we use permutations

Permuations are the number of ways of arranging n objects in r ways. It is given as ⁿPₓ = n(n - 1)(n -2)...(n - x + 1). If we have r identical objects out of n objects, the number of arrangements are n!/r!

Now, since in the date Lucy was born 11/09/1993 has eight digits, we need to find the number of permutations the eight digits of her birthday to form an eight digit code.

Since there are 8 digits, three one's, three nine's, one 1 and one 3.

The number of permutations of these digits in an eight digit code, since we have repeated objects are n = 8!/3!3!1!1!

= 40320/6 × 6 × 1 × 1

= 40320/36

= 1120 digits

So, the number of eight-digit codes could she make using the digits in her birthday is 1120 digits
