Step-by-step explanation:

Answer:

-199.1

Step-by-step explanation:

18.8% × 7= 131.6%

630×131.6=82908   move the decimal two places to the left you get 829.08

630-829.08= -199.08 round to the nearest tenth you get -199.1

Answer:

Step-by-step explanation:

Each x-value corresponds to only a single y-value.

Here, the relation is : y = 5x

This relation is injective, meaning it is a one-to-one function.

Answer:

Yes

Step-by-step explanation:

Each value in the domain corresponds to exactly one value in the range.

Answer:

The two equations of each line is

y = x + 10 and y = -x + 5

Step-by-step explanation:

volume of a sphere is = to

v= 4/3pi(r^3)

Answer: 88 ft

Step-by-step explanation:

There are 2 sides that are 26 ft (multiply 26 by 2 to get 52)

There are 2 sides that are 18 ft (multiply 18 by 2 to get 36)

Add 52 and 36 together to get 88. Don't forget to add the units so it reads 88 ft.

Answer:

128degrees

Step-by-step explanation:

180-52=128

Answer:

b = c = 75°

Step-by-step explanation:

b and 105° are adjacent angles and sum to 180° , then

b + 105° = 180° ( subtract 105° from both sides )

b = 75°

b and c are vertically opposite angles and are congruent , so

c = b = 75°

Answer:

A. It is not a function

B. It is not a function

C. It is a function

D. It is a function

Step-by-step explanation:

A relation has an input value which corresponds to an output value. When each input value has one and only one output value, that relation is a function.

The value of x which will make the provided triangles similar by the sss similarity theorem is 77.

The SSS similarity theorem is the theorem which is used to check the two triangle are similar or not.

SSS means the side-side-side. This theorem states that if all the three sides of a triangle are proportional to the three corresponding sides of the another triangle, then the triangles are similar.

In the given image, the sides of the first triangle are 35,20 and 20. The sides of the second triangle are x, 44,44.

Thus, by the SSS similarity theorem,

[tex]\dfrac{x}{35}=\dfrac{44}{20}\\x=\dfrac{44\times35}{20}\\x=77[/tex]

The value of x which will make the provided triangles similar by the sss similarity theorem is 77.

Answer:

[tex]1\frac{89}{100}[/tex] m

Step-by-step explanation:

The formula to find the area of a rectangle: [tex]l * b[/tex], where [tex]l[/tex] is the length and [tex]b[/tex] is the breadth.

1) Substitute the values into the formula.

[tex]12\frac{3}{5} = 6\frac{2}{3} * b[/tex]

2) Change it to an improper fraction and solve for [tex]b[/tex].

[tex]\frac{63}{5} = \frac{20}{3} * b[/tex]

[tex]\frac{3}{20}[/tex] * [tex]\frac{63}{5}[/tex] = [tex]b[/tex]

[tex]\frac{189}{100} = b[/tex]

3) Change it to a mixed fraction because the length is in a mixed fraction. To do it, do a long division.

= [tex]1\frac{89}{100}[/tex]

Answer:

  a) 32

  b) 2 +5n

Step-by-step explanation:

Given the stick patterns shown, with 7, 12, 17 sticks, you want to know (a) the number of sticks in pattern 6, and (b) the number of sticks in pattern n.

The numbers of sticks in the patterns shown are ...

  7, 12, 17

The differences between these numbers are ...

  12 -7 = 5

  17 -12 = 5

That is, the first pattern has 7 and the common difference between patterns is 5. This indicates the sequence is arithmetic.

The general term of an arithmetic sequence with first term a1 and common difference d is ...

  an = a1 +d(n -1)

  an = 7 +5(n -1) = 7 +5n -5

  an = 5n +2 . . . . . . sticks in pattern n

The term when n=6 is ...

  a6 = 5·6 +2 = 32 . . . . . . sticks in pattern 6

__

Additional comment

We find it easier to determine sticks in pattern 6 by first determining the formula for pattern n.

Answer:

y = [tex]\frac{\pi}{3}[/tex]

Step-by-step explanation:

using the addition formula for sine

sin(x + y) = sinxcosy + cosxsiny

then

sinxcosy + cosxsiny = [tex]\frac{1}{2}[/tex] sinx + [tex]\frac{\sqrt{3} }{2}[/tex] cosx

for the 2 sides to be equal , then

cosy = [tex]\frac{1}{2}[/tex] and siny = [tex]\frac{\sqrt{3} }{2}[/tex]

then

y = [tex]cos^{-1}[/tex] ([tex]\frac{1}{2}[/tex] ) = [tex]\frac{\pi }{3}[/tex]

and

y = [tex]sin^{-1}[/tex] ( [tex]\frac{\sqrt{3} }{2}[/tex] ) = [tex]\frac{\pi }{3}[/tex]

thus y = [tex]\frac{\pi }{3}[/tex]

[tex]\\ \rm\Rrightarrow sin(x+y)=\dfrac{1}{2}sinx+\dfrac{\sqrt{3}}{2}cosx[/tex]

[tex]\\ \rm\Rrightarrow sinxcosy+cosxsiny=\dfrac{1}{2}sinx+\dfrac{\sqrt{3}}{2}cosx[/tex]

[tex]\\ \rm\Rrightarrow cosy+siny=\dfrac{1}{2}+\dfrac{\sqrt{3}}{2}[/tex]

[tex]\\ \rm\Rrightarrow cos\dfrac{\pi}{3}+sin\dfrac{\pi}{3}=\dfrac{1}{2}+\dfrac{\sqrt{3}}{2}[/tex]

Step-by-step explanation:

theequation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

5x + 2y = - 10 ( subtract 5x from both sides )

2y = - 5x - 10 ( divide terms by 2 )

y = - [tex]\frac{5}{2}[/tex] x - 5 ← in slope- intercept form

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