Answer:
5 and 9
Step-by-step explanation:
-1 is 5 from 4 and -2 is 9 away from 7.
I hope this is helps.
Evaluate the expression for the given value of the variable
1. 8q + 6; q = 2
Plug in 2 for q in the given expression
8(2) + 6= 22
2. 9 + 4g; g = -3
9 + 4(-3) = 9 - 12 = -3
3. 7x - 7 ; x = 4
7(4) - 7 = 28 -7 = 21
4. 10 - 3.2n; n = 2
10 - 3.2(2) = 10 - 6.4 = 3.6
5. 12p + 4; p = 1.5
12(1.5) + 4= 18 + 4 = 22
6. 5w + 10 = 40
Subtract both sides by 10
5w = 30, now divide both sides by 5
w = 6
7. 4y - 12 = 60
Add both sides by 12
4y = 72
Now divide both sides by 4
y = 18
8. 10k + 5 = 65
Subtract both sides by 5
10k = 60, now divide both sides by 10
k = 6
9. 2b - 15 = 33
Add both sides by 15
2b = 48
Now divide both sides by 2
b = 24
10. 3d + 18 = 21
Subtract both sides by 18
3d = 3, now divide both sides by 3
d= 1
The total is 1164, I multiplied each cost by 2 and added all the results.
The problem did not state if the 1cm measure is the radius or diameter.
Area of a circle = π r²
Assuming: 1 cm is the radius
Area of 1 button = 3.14 * (1cm)² = 3.14cm²
Total area = 3.14cm² * 7 buttons = 21.98 cm²
Assuming: 1cm is the diameter : radius is 1/2 = 0.50cm
Area of 1 button = 3.14 * (1/2cm)² = 3.14 * 0.25cm² = 0.785cm²
Total area = 0.785cm² * 7 buttons = 5.495cm²
Answer:
The area under the line of the velocity-time graph is the distance travelled by the object in the time t.
For example u = 20m/s and t = 300 s
Distance (s) = ut = 20 x 300 = 6000 m
