Answer:
Area of an isosceles right triangle is 24.5
Step-by-step explanation:
Given that triangle is an isosceles right angle which means that two side of the triangle are equal and one of the angle is .
Consider triangle (Refer to attachment),
.
Since both sides are equal angle opposite to both sides are same.
Now applying pythagoras theorem to ,
Assume ,
Substituting the value,
Simplifying,
Dividing by 2,
Taking square root on both sides,
Formula for area of triangle is given as,
Now AB=height,BC=base.
Substituting the value,
So, area of an isosceles right triangle is 24.5
Answer:
1 x 31 OR 15.5 x 2
Step-by-step explanation:
As 31 is a prime number, the only whole numbers that do it are 1 × 31. There is another method using decimals. Ex: 15.5 x 2=31
Answer:
The answers to each part are:
Part A.
- <u>The quantity of apples is one-third of the quantity of grapes</u>.
Part B.
- <u>The quantity of apples is a quarter of the quantity of strawberries</u>.
Part C.
- <u>The number of cherries is two-elevenths of the total fruit</u>.
Step-by-step explanation:
To identify the answer in each case, you must remember that all the parts are equal, then:
Part A.
The parts of apples are 1 and the parts grapes are 3, so if you divide the first quantity with the second quantity you obtain:
So, <u>the quantity of apples is one-third of the quantity of grapes</u> or the quantity of apples is three times smaller than the quantity of grapes.
Part B.
The parts of apples are 1 and the parts of strawberries are 4, then you must divide the first quantity with the second quantity:
In this case, <u>the quantity of apples is a quarter of the quantity of strawberries</u> or the quantity of apples is four times smaller than the quantity of strawberries.
Part C.
First, you must add all the part of fruit:
- <em>1 part apple</em>
- <em>1 part orange</em>
- <em>4 parts strawberry</em>
- <em>2 parts cherry </em>
- <em>3 parts grape</em>
The total of fruits is 11 parts, taking into account the quantity of cherries is 2, now you can divide the number of cherries with the total parts of fruit:
- 2 / 11 = 2/11 (two-elevenths)
Now, you can see <u>the number of cherries is two-elevenths of the total fruit</u>.
