Answer:

.5

Step-by-step explanation:

since pemdas states that multiplication and division come in the same step, we do this in order of first to last

7/8 = .875

.875 * 4 = 3.5

3.5 / 7 = .5

Can you write the equation for a circle if the given point does not lie on the circle? Explain .
Pachacha [2.7K]

Answer:

No

Step-by-step explanation:

The equation of a circle with center (a,b) and radius r is given as:

{(x - a)}^{2}  +  {(y - b)}^{2}  =  {r}^{2}

If a given point (x,y) does not lie on this circle, it will not satisfy its equation.

This means the distance from the point to the center is not equal to the radius.

It is either less or greater than the radius.

Hence you cannot write the equation of the circle.

A pole, 90 cm long, is painted green, white, and black in the ration 3:4:2. What length of the pole is painted black?
ollegr [7]
3u + 4u + 2u = 9u
9u = 90
1u = 90/9 = 10

since black is 2u ( from the ratio given)
2u = 10 x 2 = 20

Answer : 20cm of the pole is painted black.

Abbi has $400 in $5 bills. If she has 38 bills, how many of them are $20?
Sergio039 [100]
F=5 dollar bills
t=twent dollar bills

38 total bills
f+t=38

400 in bills
400=5f+20t

we have
f+t=38
5f+20t=400
multipy first equation by -5 and add to second equation

-5f-5t=-190
5f+20t=400 +
0f+15t=210

15t=210

divide both sides by 15
t=14

subsitute
t+f=38
15+f=38
f=23


23 five dolar bills
15 twenty dollar bills

Confirm that (2x + 1)^2 + (2x^2 +2x)^2 = (2x^2 + 2x + 1)^2
Sergio [31]

Answer:

Step-by-step explanation:

(2x+1)^2+(2x^2+2x)^2=

(2x+1)^2=4x^2+4x+1

(2x^2+2x)^2=4x^4+8x^3+4x^2

4x^2+4x+1+4x^4+8x^3+4x^2=4x^4+8x^3+8x^2+4x+1

(2x^2+2x+1)^2=4x^4+8x^3+8x^2+4x+1

4x^4+8x^3+8x^2+4x+1=4x^4+8x^3+8x^2+4x+1
