Step-by-step explanation:
sana po makatulong ako
Answer:
On the first page: The two trapezoids on the left are similar.
On the second page: The two rectangles on the right are similar.
Step-by-step explanation:
Similar shapes have corresponding sides in a constant proportion.
The trapezoids on the left of the first page have a scale factor of 2.5 between the smaller and larger trapezoid between all corresponding sides, therefore are similar.
The rectangles on the right of the second page have a scale factor of 1.6 between the smaller and larger rectangle between all corresponding sides, therefore are similar.

Which dimensions can create only one unique triangle?
A.) 3 angles measuring 75 degrees, 45 degrees, and 50 degrees
B.) 3 sides measuring 14 m, 11 m, and 18 m
C.) 3 angles measuring 40 degrees, 50 degrees, and 60 degrees
D.) 3 sides measuring 3 cm, 4 cm, and 8 cm
Answers
Answer:
B)
Step-by-step explanation:
A, C, and D multiple choice answers have no chance of becoming a triangle because the lengths don't add up to either 180 or 90. Also, Triangle B follows the rule that 2 sides and be greater than the other side.
Answer: Choice B)
3 sides measuring 14 m, 11 m, and 18 m
=================================================
Explanation:
Let's go through choices A through D to see which result in one unique triangle, or could produce (infinitely) many triangles, or produce no triangles at all.
Choice A produces no triangles at all. Why is this? The angles don't add up to 180. We see that 75+45+50 = 170. The three angles must add to 180 degrees for a triangle to form. Choice B produces one single triangle, which is why it's the final answer. The triangle inequality theorem can be used here to show that a triangle can be formed. The SSS (side side side) congruence theorem is then used to show that exactly one unique triangle is possible. Choice C is a similar story to choice A. We can rule it out. This time we have the angles add to 40+50+60 = 150 which is short of 180.Choice D can be ruled out too. The two sides a = 3 and b = 4 add to a+b = 3+4 = 7, but that's smaller than c = 8. We must have a+b > c to be true if we wanted to form a triangle. For more info, see the triangle inequality theorem.Even if the angles did add to 180 (for either choice A or choice C), then we'd have infinitely many triangles and not one unique triangle. Think of dilating the triangles and how each dilated image retains the same angles. In other words, the triangles keep the same shape. Simply knowing the three angles is not enough info to create one unique triangle. We would need to know some info about the sides. This explains why AA or AAA is not a congruence theorem.

'To help built a playground, people could buy a brick with their name on it for $96. A total of $9,602 was raised, but 25 people donated an extra $50 each. How many people donated only $96?"
Answers
Answer: 87 people
Step-by-step explanation:
9,602 = 96x + 25(50)

9,602 - 1250 = 8352
8352 ÷ 96 = 87

On a certain hot summer's day, 429 people used the public swimming pool. The daily prices are 1.75 for children and 2.50 for adults. The receipts for admission totaled 885.00. How many children and how many adults swam at the public pool that day?
Answers
Answer:maybe 249.6 children and 179.4 adults
Step-by-step explanation:
C = number of children, which is also 1.75 each.
A = number of adults, which is also 2.50 each.
Since 429 used the public swimming pool, we know that C + A = 429.
Or, we can also use the expression:
1.75c + 2.50a = 885 (admission totaled 885.)
We also know that:
A = 429 - C
Take this expression substitute A with it into the original expression. We would get:
1.75c + 2.50 (429 - C) = 885
2.50 * 429 = 1,072.5
We would then get the following expression:
1.75c + 1,072.5 - 2.50c = 885
2.50 - 1.75 = 0.75
0.75c + 1,072.5 = 885
This also means:
0.75c = 1,072.5 - 885
1,072.5 - 885 = 187.5
Use distributive property to find C:
0.75c = 187.5
C = 187.5/0.75
= 250
C = 250
Now we find A:
A = 429 - C
Now we know what C is, we can calculate A using the expression above.
A = 429 - 250
= 179
Therefore, 250 children and 179 adults swam at the public pool that day.

Step-by-step explanation:
6*(2x+8) = 108
12x + 48 = 108
x =60/12
x = 5
Answer:
x = 5 units
Step-by-step explanation:
The area of a rectangle equals length times widths, therefore we can use the information from the question to make the following equation...
108 = (2x + 8)(6)
Now we just solve the equation and get...
108 = (2x + 8)(6)
108 = 12x + 48
12x = 108 - 48
12x = 60
x = 60 / 12
x = 5
Therefore, x = 5 units.
