Answer:

after 3 minutes there will be 90 gallons of water

Step-by-step explanation:

if one minute pours 30 gallons and it has been going for three minutes, that's three sets of 30 or 3*30. 3*30=90therefore there will be 90 gallons of water in three minutes.

Please help me with this question!!
tester [92]

Answer:

No

Step-by-step explanation:

Pythagorean Theorem is "a^2+b^2=c^2"

Step 1) 1^2+6^2=37

37=c^2

Step 2) The square root of 37 is 6.08

That's not 9

So they don't form a Pythagorean triple

PLSS help me with this question?
Xelga [282]

Answer:

Part a) By alternate interior angles

Part b) By vertical angles

Part c)  By AAA (Angle-Angle-Angle) Similarity Theorem

Part d) Triangles ABC and CDE are similar

Part e) b=\frac{2DE}{3}  or  b=\frac{15}{AC}

Step-by-step explanation:  

Part a)

we know that

If AB is parallel to DE

then

m<1=m<4 ------> by alternate interior angles

Part b)

we know that

m<5=m<6 -------> by vertical angles

Part c) we know that

The two triangles are similar by AAA (Angle-Angle-Angle) Similarity Theorem ------> The three corresponding angles are equal

so

m<1=m<4

m<5=m<6

m<3=m<2

Part d) we know that

If two figures are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent

therefore

Triangles ABC and CDE are similar

Part e) Find the length side of b

Remember that

If two figures are similar, then the ratio of its corresponding sides is equal

so

\frac{AB}{DE}=\frac{BC}{DC}=\frac{AC}{CE}

substitute the values

\frac{3}{DE}=\frac{2}{b}=\frac{AC}{7.5}  

b=\frac{2DE}{3}

or

b=\frac{2*7.5}{AC}=\frac{15}{AC}
