Answer:
25%.
Step-by-step explanation:
Let E be the event that the dart lands inside the triangle.
We have been given that a rectangular board has an area of 648 square centimeters. The triangular part of the board has an area of 162 square centimeters.
We know that probability of an event represents the chance that an event will happen.
Convert into percentage:
Therefore, the probability that dart lands inside the triangle is 25%.
Answer:
The answer is D, 43
Step-by-step explanation:
If the pile gets bigger by 8 each week, and you want to find out how big the pile is after 3 weeks, then you have to multiply 8
by 3 to find out how much the pile increased by.
8 × 3 = 25
Now, you need to add this to your initial value to get the answer.
25 + 17
= 42
Now simplify.
43
The correct match of each tile of the equation with its solution is:
To match each tile to the correct box, we have to solve the arithmetic operations in the box, then drag the correct tile that matches our answer into the box.
From the image attached below;
1.
n - 13 = - 12
Let us add (+13) to both sides to eliminate (-13), i.e.
n - 13 + 13 = - 12 + 13
n = 1
2.
n/5 = -1/5
multiply both side by 5
n/5 × (5) = -1/5 × (5)
n = -1
3.
n + 15 = - 10
n +15 - 15 = - 10 - 15
n = -25
