She bought 4 English books and 2 math books
27 x 4 = 108
23 x 2 = 46
108+46=154
Answer:
0=0
Step-by-step explanation:
Answer:
0.53πrad
Explanations:
Given the radius of the circular track = 60metres
If she walks a total of 100 meters, the length of the arc of the circle = 100metres
To calculate the radian angle she rotates about the center of the track, we will use the formula for calculating the length of an arc
L = θ/360° × 2πr
100 = θ/360× 2π(60)
36000 = 120π × θ
36000 = 376.8θ
θ = 36000/376.8
θ = 95.5°
Since 180° = πrad
95.5° = x
x = 95.5π/180
x = 0.53π rad
Answer:
35
Step-by-step explanation:
Given that:
Initial number of flip flop pairs = 100
After some sale:
3/5 of flip flops left are blue = 39
The number of flip flops sold :
Let number of flip flops sold = s
Initial number - number sold = number left
Number Sold = (100 - x)
3/5 of What is left = 39
Hence,
3/5 ( 100 - x) = 39
60 - 0.6x = 39
-0.6x = 39 - 60
-0.6x = - 21
x = 21 / 0.6
x = 35
X and y intercepts
get a graphing paper
when x=0 then the line intercepts or passes through the y axis
when y=0 then the line intecepts or passes through the x axis
so subsitute 0 for x and solve for the y intercept
0+3y=6
3y=6
diivded by 3
y=2
put a point on the y axis 2 units up from thhe origin (0,0) on the y axis
subsitute 0 for y and solve for x intercept
x+3(0)=6
x=6
pput a point on the x axis 6 units to the right of the origin on the x axis
now that you have 2 points, draw a straight line connecting the two points
