1) 6*10=60, 6*7=42/2=21, 21+60=81

2) 12*12=144, 12*12=144*3.14=452.16/2=226.08, 144+226.08=370.08

3) 14*5=70, 5*10=50, 70+50=120 (maybe)

4) 6*5=30/2=15, 4*3=12/2=6,15+6=21

5) 6*6=36*3.14=113.04/2=56.52, 5*5=25*3.14=78.5/2=39.25, 56.52+39.25=95.77

if right then give brainliest plz

Write the standard form of the equation of each line given the slope and y-intereept.

Elena-2011 [213]

Answer:

5y + 15x = 25, 9x - y = -4

Step-by-step explanation:

The standard form is Ax + By = C. We can make this simple by first creating the slope intercept equations of both questions:

1. y = (-3/5)x + 5

2. y = 9x + 4

For the first one, we must first get rid of the denominator by multiplying everything by 5, so we get 5y = -15x + 25, and then you can add 3x to both sides to arrive at your first standard eqn, 5y + 15x = 25.

For the second, all you need to do is swap the y and the 4, subtracting both y and 4 from each side, arriving at 9x - y = -4

PLSS give me the answer for the B and C!! ( there two different questions)

Rzqust [24]

Answer:

Circumference Formula :

$2\pi r$

$\frac{120}{360}$

This is the ratio we can work out:

$\frac{given \: angle}{revolution} = ratio$

$arc = ratio \times circumference$

$22 = \frac{120}{360} \times 2 \times \frac{22}{7} \times r$

$22 = \frac{44}{21} x$

$x = 22 \div \frac{41}{21}$

$x = \frac{21}{2}$

Here are ten numbers

ser-zykov [4K]

Solution,

Given data=3, 7 , 2 , 4, 7, 5, 7, 1, 8, 8

a.Mode= 7 because it has more frequency in comparison to others.

b.Arranging the data in ascending order:

: 1,2,3,4,5,7,7,7,8,8

N(total number of items)=10

Median=(N+1/2)th item

 = (10+1/2)th item

 = (11/2)th item

 = 5.5th item

Again,

5th item+6th item/2

 = 5+7/2

=12/2

= 6

c. summation FX=52

 N=10

Mean= summationfx/N

 =52/10

 =5.2

D. Range= highest score- lowest score

 = 8-1

 =7

Hope it helps

Good luck on your assignment
