Answer: There are 57 quarters and 33 dimes.

Step-by-step explanation:

let x = Number of quarters

y= Number of dimes

As per given , we have

x+y = 90  (i)

0.25x+0.10y= 17.55  (ii)

Multiply 10 on both sides of (ii)

2.5x+y= 175.5    (iii)

Eliminate (i) from (iii) , we get

1.5x = 85.5

⇒ x= 57

Put value of x in (i) , we get

57+y=90

⇒  y= 90-57

⇒  y= 33

Hence, there are 57 quarters and 33 dimes.

Answer:

23.1

Step-by-step explanation:

The radius of the cone is

32÷2

16

So the equation is

s²=r²+h²

h²=s²-r²

h=√s²-r²

h=√28.1²-16²

h=√789.61-256

h=√533.61

h=23.1

Answer:36+2 divided by x=A

Step-by-step explanation:

Answer:

Slope: (y2-y1)/(x2-x1)

(4+2)/(-16-5) = 6/-21 = -2/7

Y = -2/7x + b

5 = -2/7(-2) + b, b = 31/7

Equation: y = -2/7x + 31/7

The marks are the same, but they aren't placed in the same position in the triangles.

Answer:

Its D i had to guess but got it right :)

Step-by-step explanation:

Ok y is your y value from any point on the graph m is your slope x is the x value of any point from the graph and b is your y intercept that is where the line cross in the y line that is the vertical line in the graph

Answer:

As simple as possible, it's a form of linear equations.

Step-by-step explanation:

The formula, y = mx + b, can be dissected to get the slope and y-intercept of a linear equation where:

  m = slope

  b = y-intercept

  (x and y can be substituted for any point)

For solving such problems we need to recall equations .

⠀⠀⠀⠀

When the value of two variable comes equal and zero in an equation then that equation is said to have infinitely many solutions . If the value of a variable have any particular constant then the equation is said to have one solution . If the value of of any variable comes undefine then the equation is said to have no solution .

➠ 8( 3x - 6 ) = 6(4x + 8 )

➠ 24x - 48 = 24x + 48

Now, we will bring the variable on left hand side and constants on right hand side

➠ 24x - 24x = 48 + 48

➠ 0 = 48 + 48

➠ 0 = 96

As we can see the equation have end with a undefined value the equation have no solutions

Answer: BBBBBB

Step-by-step explanation:

The correct option is,

"Yes because all the elements of set R are in set A"

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given the following sets;

U = {x | x is a real number}

A = {x | x is an odd integer}

R = {x | x = 3, 7, 11, 27}

Hence, The elements of the set A are,

⇒ A = {1, 3, 5, 7, 9, 11...}

R ⊂ A can be interpreted as R is a subset of A

i.e all the elements of R can be found in A.

Since, all the elements of R are all odd integers and can be fi=ound in A, hence R ⊂ A is TRUE.

The correct option is "Yes because all the elements of set R are in set A"

Answer:

The correct answer is B. 25 minutes.

Step-by-step explanation:

Here, we know that a horse takes 60 breaths every 5 minutes. We need to find how many minutes it takes a horse to take 300 breaks. First, let's see how many times 60 can go into 300.

300 ÷ 60 = 5

Now, let's multiply this by 5.

5 x 5 = 25

Therefore, the answer is B. 25 minutes.

Step-by-step explanation:

In any rhombus, the four sides are the same length.

Because of this, we know that

Furthermore, AC = AC due to the reflective property

Those three facts then allow us to prove triangle ACD is congruent to triangle ACB through the SSS congruence property. Then from CPCTC, we then know that  angle DAC = angle BAC,  which is enough to show that AC bisects the angle shown. The term "bisect" means "cut in half".

Answer:

34, 15, -4, -23 and -42

Step-by-step explanation:

We are to find the first five sequence

when n = 1

f(2) = f(1) - 19

f(2) = 34 - 19

f(2) = 15

when n = 2

f(2+1) = f(2) - 19

f(3) = f(2) - 19

f(3) = 15 - 19

f(3) = -4

when n = 3

f(3+1) = f(3) - 19

f(4) = f(3) - 19

f(4) = -4 - 19

f(4) = -23

when n = 4

f(4+1) = f(4) - 19

f(5) = f(4) - 19

f(5) = -23 - 19

f(5) = -42

Hence the first five terms  in the arithmetic sequence are 34, 15, -4, -23 and -42

-1, - 0.8, - 0.6, - 0.4, - 0.2, 0, 0.2, 0.4, 0.6, 0.8, 1

–1 is less than Negative StartFraction 4 Over 5 EndFraction : - 1 < - 0.8 (true)

–0.3 is less than One-fifth : - 0.3 < 0.2 (true)

0.6 is greater than 1 ( false)

Answer:

26.55°C

Step-by-step explanation:

21.85 + 4.7

Average maximum daily temperature = 21.85°C

Average minimum temperature = - 4.7°C

The average daily maximum temperature is x°C higher than the average daily minimum temperature ;

x = (maximum temperature - minimum temperature)

x = (21.85 - (-4.7))°C

x = (21.85 + 4.7)°C

x = 26.55°C

Hence, The average daily maximum temperature is 26.55°C higher than the average daily minimum temperature
