Harry needs £400 to buy a new computer. He has saved £160 so far. What percentage has Harry saved

Roman55 [17]

He has £160 out of £400 saved up. Just rewrite that as a fraction and then there are two ways to finish it off.

The first way would be to just divide.
$\frac{160}{400}=.4$
Then turn that decimal into a percentage by multiplying by 100.
$.4(100)=40$
40%

The second way would be simplify the fraction until the denominator is 100. The numerator is your answer.
$\frac{160}{400}=\frac{40}{100}$
40%

Harry has saved 40%.

Select the equation in which the graph of the line has a negative slope and the y-intercept equals 10.

PolarNik [594]

That would be C.

20x + 5y = 50
5y = - 20x + 50
y = -20/5x + 50/5
y = - 4x + 10
now in y = mx + b form. the m represents ur slope and the b represents ur y intercept. So here, u have a slope of -4 and a y intercept of 10.

The midpoint of AB is M ( 1 , − 3 ). If the coordinates of A A are ( − 6 , − 7 ),what are the coordinates of B?

Leno4ka [110]

Answer:

a= -4

b=1

Step-by-step explanation:

Midpoint=(1,-3)=(x,y)

A=(-6,-7)=(x1,y1)

Let ,the coordinates of B be 'a and b' .

So,

B=(a,b)=(x2,y2)

Using ,midpoint formula,

(x,y)=(x1+x2\2 , y1+y2 \2)

or, (1,-3)=(-6+a\2 , -7+b \2)

Now,

Taking the corresponding sides,

or, 1 =-6+a/2

or, 1*2=6+a

or, 2=6+a

or, 2-6=a

a=-4

Then,

-3= -7+b/2

or, -3*2= -7+b

or, -6 =-7+b

or, -6+7=b

b=1

hram777 [196]

Answer:

$m > 5$

Step-by-step explanation:

$\frac{m + 4}{3} > 3 \\ \frac{m + 4}{3} \times 3 > 3 \times 3 \\ m + 4 > 9 \\ m + 4 - 4 > 9 - 4 \\ m > 5$
