Answer:

21/8

Step-by-step explanation:

KCF or keep change flip. keep 7/8. turn divide into multiply, then flip 1/3 to 3/1. 21/8 is what you get. Hope this helped!

Answer:

21/8

Step-by-step explanation:

Dividing by a fraction is like multiplying with the inverse:

So (7/8) / (1/3)

is the same as

(7/8) * (3/1) = (7/8) * 3 = 21/8

21/8 cannot be simplified, unless you find 2  5/8 simpler

Answer:

The coordinates of point B are: (29,-15)

Option D is correct option.

Step-by-step explanation:

Endpoint of diameter of a circle = A(5,7)

Centre of circle = P(17,-4)

We need to find coordinates of other endpoint of diameter of a circle i.e. B

The formula used is: [tex]Midpoint=(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})[/tex]

We are given coordinates of centre (midpoint) P(17,-4)

and A (5,7) x₁=5, y₁=7

We need to find Point B i.e. (x₂,y₂)

Putting values and finding point B

[tex]Midpoint=(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})\\(17,-4)=(\frac{5+x_2}{2}, \frac{7+y_2}{2})\\We\:can\:write:\\17=\frac{5+x_2}{2}\:and\: -4=\frac{7+y_2}{2}\\17\times 2=5+x_2\:and\: -4\times 2=7+y_2\\34=5+x_2\:and\: -8=7+y_2\\34-5=x_2\:and\: -8-7=y_2\\x_2=29\:and\: y_2=-15[/tex]

so, we get: x₂ = 29 ,y₂ = -15

The coordinates of point B are: (29,-15)

Option D is correct option.

4(x+3)+4x=28

Solve

4x+12+4x=28

Combine

8x+12=28

Isolate

8x=16

Isolate

x=2

Substitute

4(2+3)=20

4*2=8

Now find each side

20/4=5

8/4=2

So one side is 5

Other side is 2

Answer:

Step-by-step explanation:

The limit of any polynomial function at a point is the value of the polynomial at that point. A polynomial is defined and continuous for all values of the independent variable.

The limit of a rational function at a "hole" is the value of the simplified function at that point.

1a) lim = 4+3+2-2 = 7

1b) lim = (3)(-3)(3) = -27

1c) lim = 3^2+9 = 18

1d) lim = (x+4) = 4+4 = 8

1e) lim = 3x+1 = 3(1/3) +1 = 2

1f) lim = x^2/x^2 = 1

_____

The expressions of (e) and (f) can be simplified by factoring the difference of squares: a^2 -b^2 = (a -b)(a +b). In each case, one of the factors cancels the one in the denominator, so the remaining function can be evaluated at the limit point.

As x approaches infinity, the only terms of a rational expression that matter are those of the highest degree in numerator and denominator. (There's a little more to it if the numerator has a higher degree than the denominator.)

THANK YOU

Expression is a set of numbers, variables, and mathematical operations. The standard form of the expression (-7x+5)-(2x²–8x+6) is -2x²+x-1.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

As the expression is given to us (-7x + 5) - (2x² – 8x + 6), in order to simplify the problem we need to open the brackets. therefore, the expression can be solved as,

[tex](-7x + 5) - (2x^2 - 8x + 6)\\\\= -7x + 5 - 2x^2 + 8x - 6\\\\ = -2x^2+8x-7x-6+5\\\\=-2x^2 + x - 1[/tex]

Hence, the standard form of the expression (-7x+5)-(2x²–8x+6) is -2x²+x-1.

Answer:

Arianna should receive $3.05 in change.

Step-by-step explanation:

In order to find the answer, you have to find the cost of the three balls by multiplying the cost per ball for the number of balls and then, you have to subtract this amount from five to find the change Arianna should receive:

$0.65*3=$1.95

$5-$1.95=$3.05

According to this, the answer is that Arianna should receive $3.05 in change.

Answer:

The batch of jam from this summer

Step-by-step explanation:

Every summer, Ronald makes cranberry-pear jam with the fruit he collects from his garden.

For last summer

Last summer, he used 3 cups of cranberries and 5 cups of pears to make his jam.

Hence,

5 cup of pears = 3 cups of cranberries

1 cup of pears = x

Cross Multiply

5x = 3

x = 3/5

x = 0.6

1 cup of pears = 0.6 cup of cranberries

For this summer

This summer, Ronald decided to make an even larger batch using 5 cups of cranberries and 8 cups of pears.

Hence,

8 cup of pears = 5 cups of cranberries

1 cup of pears = x

Cross Multiply

8x = 5

x = 5/8

x = 0.625

1 cup of pears = 0.625 cup of cranberries

From the above calculation we can see that the quantity of cranberries to 1 cup of pears from this summer is higher than that of last summer

Therefore, the batch of jam that tasted more like cranberries is the batch of jam from this summer

Answer:

This summer’s batch jam tasted more like cranberries.

A scale factor of 4in to 5in should be used

Step-by-step explanation:

Given

[tex]Original\ Measurement = 4.5\ in[/tex]

[tex]Scale\ Measurement = 3.6\ in[/tex]

Required

Determine the scale to use

The scale to use can be represented as:

[tex]Scale = Scale\ Measurement : Original\ Measurement[/tex]

This gives:

[tex]Scale = 3.6\ in : 4.5\ in[/tex]

Divide by 0.9

[tex]Scale = \frac{3.6}{0.9}\ in : \frac{4.5}{0..9}\ in[/tex]

[tex]Scale = \frac{3.6}{0.9} : \frac{4.5}{0.9}[/tex]

[tex]Scale = 4 : 5[/tex]
