Tom has 7/8 gallons of paint. He used 1/2 gallon of paint on a project. He uses the steps to show how much paint he had when he

WINSTONCH [101]

He made his mistake in Step 2. Tom should have subtracted 4/8 instead of 1/8. The mistake is that he was not consistent when he multiplied Denominators (bottom number) must be the same when handling fractions so Tom must multiply both the numerator and denominator by the SAME number to balance it out. 1/2 x 4/4= 4/8. Subtract. 7/8 - 4/8= 3/8. Tom has 3/8 of a gallon of paint leftover.

HELP ME FIND THE ANGLE<br><br><br><br><br> HELP ME FIND ANGLE A

romanna [79]

Answer:

32 degrees

Step-by-step explanation: So they tell you BE is congruent to BC so triangle BCE is isosceles. We know that angle C is 35 degrees and the triangle is isosceles so angle E is 35 degrees too. Now we do 180-(35+35) and that equals 110 so angle B is 110. And we know that angle EBC and FBA are supplementary angles so 180-110 is 70 degrees so angle FBA is 70 degrees and you can do the same thing with angle DFB and AFB so 180-102 degrees is 78 degrees and to find angle a you just do 180-(70+78) and that equals 32 degrees so angle A is 32 degrees. :)

ASAP please help I’m failing math

Answer:

Part A) The volume of the entire cone is $168\pi\ in^3$

Part B) see the explanation

Step-by-step explanation:

Part A) we know that

The volume of a cone is equal to

$V=\frac{1}{3}\pi r^{2}h$

where

r is the radius of the base of the cone

h is the height of the cone

In this problem triangle ABD is similar to triangle ACE

Remember that If two figures are similar, then the ratio of its corresponding sides is proportional

so

$\frac{AB}{AC}=\frac{BD}{CE}$

substitute the given values

$\frac{7}{14}=\frac{3}{x}$

solve for x

$x=14(3)/7\\x=6\ in$

To find out the volume of the entire cone we have

$r=CE=x=6\ in$

$h=AC=14\ in$

substitute in the formula

$V=\frac{1}{3}\pi (6)^{2}(14)$

$V=168\pi\ in^3$

Part B) How did you determine the value for x in triangle ACE

In this problem triangle ABD is similar to triangle ACE

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

so

$\frac{AB}{AC}=\frac{BD}{CE}$

substitute the given values and solve for x
