Hi I have no idea how to do this question :)

Mathematics
1 answer:
erik [133]2 years ago
7 0

Answer:

A. 36

Step-by-step explanation:

Because the two angles at the bottom of both the triangles are congruent, the two triangles are similar. Therefore, the corresponding side lengths of the triangles must be proportional to each other

if the area of a triangle is hb/2,

(with h=length of height, b=length of base)

the height of the first triangle is:

25 = 10h/2

50 = 10h

h=5

you can write ratios representing the proportions of the two triangles:

5/x = 10/12 (with x=height of second triangle)

x=6

then find the area of the second triangle with the height (6) and base (12)

(6*12)/2 = 36

Jackson picked apples for his family. He picked a total of 8 1/4 pounds. He took 3 3/4 pounds to his aunt and 2 3/8 to his mothe
GalinKa [24]

Answer: 2 1/8 pounds of apples were left to give his grandmother.

Step-by-step explanation:

He picked a total of 8 1/4 pounds. Converting 8 1/4 pounds to improper fraction, it becomes 33/4 pounds.

He took 3 3/4 pounds to his aunt. Converting 3 3/4 pounds to improper fraction, it becomes 15/4 pounds.

He also took 2 3/8 to his mother. Converting 2 3/8 pounds to improper fraction, it becomes 19/8 pounds.

The total number of apples that he gave to his aunt and mother is

15/4 + 19/8 = 49/8 pounds

The number of pounds of apples left to give his grandmother is

33/4 - 49/8 = 17/8 = 2 1/8 pounds

Consider the Inequalities X >7 and X < 12 select all the values that satisfy both Inequalities
Maksim231197 [3]

Answer:

9;10

Step-by-step explanation:

What we can first do is make them into one double sided inequality and then interpret it from there.

After combining them we get: 7<x<12

This means that any number between 7 and 12 can be picked.

Keep in mind, this means that 7 and 12 cannot be picked, they have to be in between.

Therefore, we get our aswers of 9 and 10!
