Given:
A race car game takes 6 points from a player each time the player hits a cone.
To find:
The integer which represents the change in total points if the player hits 10 cones.
Solution:
According to the given information,
1 hit = -6 points
Here, negative sign represents the reduction in points after hitting a cone.
If the player hits 10 cones.
(1 × 10) hit = (-6 × 10) points
10 hit = -60 points
So, the change in total points if the player hits 10 cones is -60.
Therefore, the required integer is -60.
Answer:
YES
Step-by-step explanation:
Given the equations representing two lines:
2x - y = -3 ----› Equation 1
-6x - 2y = -6 -----› Equation 2
Multiply equation 1 by 2, and multiply equation 2 by 1.
2x - y = -3 ----› Equation 1 × 2
-6x - 2y = -6 -----› Equation 2 × 1
4x - 2y = -6
-6x - 2y = -6
Subtract both equations
10x = 0
Divide both sides by 10
x = 0/10
x = 0
Substitute x = 0 into equation 1
2x - y = -3
2(0) - y = -3
0 - y = -3
-y = -3
Divide both sides by -1
y = 3
Thus, the solution would be (0, 3).
Answer:
50%
Step-by-step explanation:
If there were 100 people in the survey and there were 50 girls and 50 boys, then the boys made up 50% of the population for the survey.
If it descends, it means it goes down/ decreases. so 90-105, will get you to negative 15 (-15)
Answer:
i) 441π cm² ≈ 1385.4 cm²
ii) 196π cm² ≈ 615.8 cm²
Step-by-step explanation:
The areas of circles with radius 21 cm or diameter 28 cm can be found using the appropriate area formula.
<h3>i)</h3>
The formula for the area of a circle based on its radius is ...
A = πr²
When the radius is 21 cm, the area is ...
A = π(21 cm)² = 441π cm² ≈ 1385.4 cm²
<h3>ii)</h3>
The formula for the area of a circle based on its diameter is ...
A = (π/4)d²
When the diameter is 28 cm, the area is ...
A = (π/4)(28 cm)² = 196π cm² ≈ 615.8 cm²
