what is the 10% of 3000?​

Answer:

Step-by-step explanation:

slope=(-4-8)/(-2-4)=-12/-6=2

eq. of line is

y-8=2(x-4)

y=2x-8+8

y=2x

Answer:

$56.25

Step-by-step explanation:

Not sure if I can explain this too well but

This question is basically asking what 25% of 75 is

To find that you would multiply 75 x 0.25:

75x0.25=18.75

Now we know that the question is saying that we can take $18.75 off the original total($75) to find the discount total

So we would simply subtract $75 by $18.75 to find the final price:

75-18.75=56.25

So our total is equal to $56.25

Step-by-step explanation:

I guess you want to solve for n.

in that case

-2 = 0.8n

n = -2/0.8 = -2 / 8/10 = -2 × 10/8 = -5/2 = -2.5

Answer:

Step-by-step explanation:Slope m = yB − yA xB − xA Slope m = y B - y A x B - x A. Solution: Slope m = 10 − 2 7 − 3 Slope m = 10 - 2 7 - 3. = 8 4 = 8 4. m = 2.

The equivalent equation is x - 4 = 0.

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Simplification is to make something easier to do or understand and to make something less complicated.

Given

The expression is [tex]\rm log_3(x + 5) = 2[/tex].

The equivalent equation.

The expression is [tex]\rm log_3(x + 5) = 2[/tex].

On simplifying. we get

[tex]\begin{aligned} \rm log_3(x + 5) &= 2\\x + 5 &= 3^2\\x + 5 &= 9 \\x &= 9 - 5\\x &= 4\\x - 4 &= 0\\\end{aligned}[/tex]

The equivalent equation is x - 4 = 0.

Answer:

3^2=x+5

Step-by-step explanation:

The correct option is C - 3^2 =x+5

The equation is \log _{3}(x+5)=2

Option A: \log _{3}(x+5)=3^{2}

This is not possible because using logarithmic rule, if \log _{a} b=c then b=a^{c} - This doesn't work out.

Option B: \log _{3}(x+5)=2^{3}

This is not possible because using logarithmic rule, if \log _{a} b=c then b=a^{c} - This doesn't work either.

Option C: x+5=3^{2}

This is possible because using logarithmic rule, if \log _{a} b=c then b=a^{c} - This works and It's equal

Option D: x+5=2^{3}

This is not possible because using logarithmic rule, if \log _{a} b=c then b=a^{c} - This doesn't work also.

Answer:

its 0.9 which is 90 I Literally divided it

Step-by-step explanation:

£6.30 divided by 7 is equal to 90 pence.

In mathematics, the division operation splits left-hand operands into right-hand operands. The division's primary goal is to create equal groups or to ascertain how many individuals are in each category following a fair distribution.

For example 4/2 = 2

To convert £6.30 to pence, we multiply it by 100 because there are 100 pence in 1 pound.

£6.30 x 100 = 630 pence

Now, to calculate 630 pence divided by 7:

630 pence / 7 = 90 pence

Therefore, £6.30 divided by 7 is equal to 90 pence.

Answer:

1/5

Step-by-step explanation:

forward 5 units and up 1

Step-by-step explanation:

25 questions, 2 points each.

that means there were 25×2 = 50 points in total.

Gideon got 42 out of the 50.

100% = 50

1% = 100%/100 = 50/100 = 0.5

42 is how many % ? as many as 1% (0.5) fits into 42.

so,

42/0.5 = 42×2 = 84%

Total area=160 cm2

This is really weird because the numbers dont look proportional to the shape but according to the data it should be correct :/

Answer:

Area of A=120cm²

Area of B=20cm²

Area of C=20cm²

Total area=160cm²

Step-by-step explanation:

For A

[tex]Length(l)=15cm\\Breadth(b)=8cm\\Now,\\Area=l*b\\Area=15cm*8cm=120cm^{2}[/tex]

For B

[tex]Length(l)=5cm\\Breadth=12cm -8cm=4cm\\Now,\\Area=l*b\\Area=5cm*4cm\\Area=20cm^{2}[/tex]

Area of C=20cm²

Total Area=160cm²

Step-by-step explanation:

Answer:

2) A, 3) Shawn is looking for a good book, he reads 12 books and then decides to read 1/4 of the amount he already read. How many books has Shawn read in total? 4) A, C, E. 5) 4

Step-by-step explanation:

2) Elena already walked 12 miles, she then walks another 1/4 of those 12 miles. The answer is A.

3) Shawn is looking for a good book, he reads 12 books and then decides to read 1/4 of the amount he already read. How many books has Shawn read in total?

4) to find the answers figure out how much they multiply one number by and multiply the other number by that amount. For example, the ratio 2:5 can be the same as 4:10 because you are multiplying the original ratio by 2 to get the new ratio.

5) The diameter of a circle is the length of one side to another. to find the length of the outer edge you need to find the circumference. To find the circumference of a circle you must use [tex]\pi[/tex]*Diameter. To find the answer we must use 180/[tex]\pi[/tex]D. Since pi can not be defined we will use 3.14 as a rough estimation. 3.14*12=37.68. 180/37.68=4.777070064. Since it doesn't make much sense to do .8 of a invitation then we must round down. The answer is 4.

Answer:

Part A: by finding equation and x value is size.

Take two coordinates: (20, 1/5), (40,2/5)

slope:

[tex]\frac{y2-y1}{x2-x1}[/tex]

[tex]\frac{\frac{2}{5} -\frac{1}{5} }{40-20}[/tex]

[tex]\frac{0.2}{20}[/tex]

[tex]0.01[/tex] ......this is slope, unit rate.

Equation:

y - y1 = m( x - x1 )

y - 1/5 = 0.01(x - 20)

y = 0.01x ........this is the equation

The y determines the size of kilowatts of energy

So y = 5

5 = 0.01x

x = 500 square feet

500 square feet is required to produce 5 kilowatts of energy.

Answer:

x=5

Step-by-step explanation:

−8(x−1)=−32

(−8)(x)+(−8)(−1)=−32

−8x+8=−32

Step 2: Subtract 8 from both sides.

−8x+8−8=−32−8

−8x=−40

Step 3: Divide both sides by -8.

−8x    -40

−8   =−8

Answer:

Step-by-step explanation:

The sum of interior angles of a triangle = 180°

Therefore,  ∠ABC + ∠BAC + ∠BCA = 180°

                          ⇒ 42 + 64 + ∠BCA = 180°

                                           ⇒ ∠BCA = 180 - 42 - 64
