Answer:
Step-by-step explanation:
70(10/100)=7 broken cookies.
7/70=1/10 is the fraction broken
(70-7)/70=63/70 is the fraction remaining whole
3.5 / 2 = $1.75
answer is B
cost of one pen: $1.75
Answer: The last option.
Step-by-step explanation:
1. Calculate the area of the rectangle as following:
2. Find the base of the triangle applying the Pythagorean Theorem. Then:
3. Then, the area of the right triangle is:
4. The area of the trapezoid is the sum of the area of the triangle and the area of the rectangle. Then:
Answer:
The third one.
Step-by-step explanation:
Let us recall parallelogram properties, which states that opposite angles of parallelogram are congruent.
We can see from graph that side US is parallel to TR and measure of angle U equals to measure of angle R, therefore, quadrilateral drawn in our given graph is a parallelogram.
Since we know that opposite sides of parallelogram are congruent. In our parallelogram UT=SR and US=TR.
In our triangle STU and triangle TSR side TS=TS by reflexive property of congruence.
Therefore, our triangles are congruent by SSS congruence.
