Not positive, but I think the lower one is     leaf   bird    earth   panda

do you mean inbetween square root of 12 and square root of 52 or just square root of 12 and 52?

1. 

Pennies:$\dfrac{50}1=\boxed{50}$

Nickels: $\dfrac{2\cdot100}5=\boxed{40}$

Dimes: $\dfrac{5\cdot100}{10}=\boxed{50}$

Quarters: $\dfrac{10\cdot100}{25}=\boxed{40}$

2.

$0.5+2+5+10=\boxed{\$17.5}$

The base times the height, as you may know, is equal to the area of a rectangle. Once you half that, it becomes the area of a triangle. Let me explain more:

(Picture of right triangle)

As you can see, this triangle is a right triangle. I am only choosing this because it is the easiest to explain. Once you take another right triangle with exactly the same measurements, you can see in the picture below how it becomes a rectangle.

Because of this, the area of a triangle is equal to the area of the rectangle divided by two, or the base times the height divided by two, or, 1/2*B*H

if there are 4 two dollar notes, that means there are 8 dollars the are made up of two dolar notes. so 23-8=15, which is the total of the 5 dollar notes, so 15/5=$\boxed3$ five dollar notes

We're looking for the LCM of 3750, and 6000. the way I would do it is find the GCD of the two numbers, then multiply 3750 and 6000 together and divide it by the GCD:

6000-3750=2250

3750-2250=1500

2250-1500=$\boxed{750}$

$\dfrac{3750\cdot6000}{750}=5\cdot6000=\boxed{30,000 }$ miles

Plz help me on both of them

ohh, nice job. :))

20pi + 5*sqrt(2)  = 69.9

   so all of the integers from -69   to + 69 = 139 integers

From yesterday:

976 p / 4h =  244 p/h     or   244 pens per hour

244 p/h  *   1/2  hr = 122 pens in 1/2 hour

4/6*150 = 100

\(6\times 14\times 12=1008\)

\((1-\frac{50}{100})\times 1008=\frac{1}{2}\times 1008=504\)

18.30-8.50=9.8

\( 9.8+18.3=28.1\)

Notice that AC is equal to the sum of the radius and EC. We know that AB is the radius, and AB is 5 ft, so AC must be equal to 5 ft + 8 ft = 13 ft.

Since BC is tangent to circle A, AB is perpendicular to BC, so ABC is a right triangle. 

Let BC equal x. To find BC, use the Pythagorean theorem:

\(5^2+x^2=13^2\\25+x^2=169\\x^2=144\\x=\boxed{12}\)

small no.= x

larger no.= y

three times the sum of two numbers in 51

3(x+y)=51 -------equ 1

the larger number is plus four twice the smaller number.

y=2x+4  -------equ 2

substitute y=2x+4

3(x+2x+4)=51

3(3x+4)=51

9x+12=51

9x=39

x=4.33

y=12.67

4321432143214321412342132134

y = -2x + 20

6x - 5y = 12

6x - 5(-2x + 20) = 12

6x + 10x - 100 = 12

16x = 112

x = 7

y = -2x + 20​

y = -2*7 + 20

y = 6

The answer seems to be correct. 

Thanks for answering. 

Only feedback is that I followed through with your solution. And the exact solution would be 11 and 2/3 percent

Let x = Jacob
John has 9x 

9x - 12 = x + 12

8x = 24

x = 3

This means Jacob has 3 toys and John has 3 x 9 = 27 toys.

3 + 27 = 30 toys altogether

I think g(1) is actually g(2*1-5)

=^._.^=

I think you would have to set x as 3, since 2*3-5 = 1. 

So 3*6+9 = 27

=^._.^=

let x = percentage of cream in final mixture

6 * 0.1 + 3 * 0.15 = 9x

0.6 + 0.45 = 9x

1.05 = 9x

x = 0.116666666...

which means the percentage is about 11.67%
