Answer:

75 percent

Step-by-step explanation:

percent increase = increase/original ×100

= (35-20)/20 ×100 =15/20 ×100= 15×5= 75

Answer:

25,709.4

Step-by-step explanation:

First you would multiply 3.5 x 24,000, and then divide by 100, to get 840, and then add that to the original  amount to get 24,840, and that is the cost for one year. And then you would multiply 24,840 by 3.5 and then divide by 100 to get 869.4. Finally just add that to 24,840 to get 25,709.4, and that is the cost for 2 years. I hope this helps :)

The cost of college in two years is $25709.4.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Cost of Faber college  = $24000

Rate of increase = 3.5%

The cost of college after one year.

= 103.5% of 24,000

= 103.5/100 x 24000

= $24,840

The cost of their college after two years.

= 103.5% of 24,000

= 103.5/100 x 24,840

= $25709.4

Thus,

The cost of college in two years is $25709.4.

I ain't Joseph but what's wrong?

Answer:

D=12h

Step-by-step explanation:

We can see easily this is an even number, so let's first divide by 2.

432=2*216

We can see the remaining 216 is still even so we continue.

432=2*2*108

And continue

432=2*2*2*54

and continue

432=2*2*2*2*27

Now we can see that 27 is a multiple of 3 in fact its 3^3.

So we can conclude that 432=[tex]2^4*3^3[/tex]

Answer:

Step-by-step explanation:

Answer:

y = 4x - 9

Step-by-step explanation:

y = mx + b

m = slope

b = y-intercept

the y-intercept is when the line crosses the y axis, and in this case we can see it at "-9"

The slope we can do rise over run "r/r" ot "y/x"

r/r = 4/1 = 4

The line is positive since its going up

y = 4x - 9

Step-by-step explanation:

4x + 6 + 3x + 21 = 8x + 7

7x + 27 = 8x + 7

-x + 27 = 7

-x = -20

x = 20

m<3= 8(20) + 7

         160 + 7 = 167

m<1= 4(20) + 6 = 80 + 6 = 86

Answer:

12.25 is one possible number but any number between 9 and 16 works (although the square root may not always be a whole number)

Step-by-step explanation:

A number between 3 and 4 is 3.5.

3.5² = 12.25

The percentage is 75%, the amount is 45 and the base is 60 so option (D) will be correct.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

The percentage is just like the amount of that value but between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.

Given that 45 is some percentage of 60

So, 60 will be the base because we are calculating the percentage of it and the amount will be 45.

Let's say 45 is x percentage of 60

Then,

60 × x/100 = 45

x = 4500/60

x = 75%

Percentage will be 75

Hence "The percentage is 75%, the amount is 45 and the base is 60".

Answer:

A = 50°

Step-by-step explanation:

[tex](2x - 10) + (x + 30) + 70 = 180 \\ 2x + x = 180 + 10 - 30 - 70 \\ 3x = 90 \\ x = \frac{90}{3} \\ x = 30[/tex]

Then

[tex]a = 2x - 10 \\ a = 2(30) - 10 \\ a = 60 - 10 \\ a = 50[/tex]

Actually Welcome to the Concept of the Triangles.

Since we know that, the Angle sum property of a triangle is equal to 180°.

means that, <A + <B + <C = 180°

so we can write as,

==> 2x-10 + x + 30 +70 = 180°

===>3x +90 = 180

==> 3x = 90

hence, x = 30°

so now, substitute angle x,

So angle A is => 2(30)-10 => 60-10 = 50°

hence Angle A = 50°.

Answer:

Step-by-step explanation:

x=number of cups of coffee

y=number of cups of hot chocolate

1.75x+1y=14.5

x+y=10    y=10-x

substitute for y

1.75x+10-x=14.5

0.75x=4.5

x=6

y=10-6=4

Answer:

18+2x

Step-by-step explanation:

Let the number be x.

Translate: 2x + 18 = x - 4.

Subtract x from each side:  x + 18 = -4.

Subtract 18: x = -22.

Check:  2(-22) + 18 = -44 + 18 = -26;  -22 - 4 = -26.

8 increased by twice a number​  = 18+2x
