Answer:
<em>is the total amount.</em>
<em> </em>
Step-by-step explanation:
The first step in this problem is to figure out how much of a tip was left. To find that out, you need to multiply the percentage by the total of the meal.
We know that 11.34 was how much of a tip that was left,
To figure out the total amount that was spent, you would add the total amount and the tip.
Answer:
Step-by-step explanation:
5(x+1), when expanded, becomes 5x + 5, which is ot the same as 5x + 1.
Answer:
19/50, 9/20, 2/5
Step-by-step explanation:
it's easier to solve if you change 3/6 and 3/8 to decimals which is
0.5 and 0.375 so all you have to do is put in any number between those decimals then change to fractions
Answer: Answer Number 1; Line AB is similar to
line EF
Line BC is similar to line FG
Line CD is similar to line GH
Line DA is similar to line HE
Step-by-step explanation: First and foremost both
quadrilaterals are similar but of varying dimensions.
If we label both trapezoids as ABCD and EFGH
respectively, then it follows that the corresponding
lines (as stated in the answer above) would also be
similar.
Same applies to the four angles in the interior of the
trapezoids.
Number 2, Angle A equals Angle E
Angle B equals Angle F
Angle C equals Angle G
Angle D equals Angle H
Number 3,
If the scale factor between both figures is 2:3, then
for every length of a side in figure ABCD, the
corresponding side in figure EFGH would be
multiplied by 3/2.
Therefore if AD is 8cm, then EH equals 8 x 3/2
That gives us 12cm.
If GH is 6cm, then DC equals 6 x 2/3. That gives
us 4cm.
If AB is 3 times the length of DC, then AB equals 3
x 4, that gives us 12cm.
If AB is 12cm, then EF equals 12 x 3/2. That gives
us 18cm.
Take note that the shapes are both isosceles
trapezoids, o we have two sides of equal length, AD
and BC in the first figure and then EH and FG in the
other figure.
The first trapezoid has sides 8cm, 12cm, 8cm and
4cm. The perimeter is given as 8+12+8+4 32cm.
The second trapezoid has sides 12cm, 18cm, 12cm
and 6cm. The perimeter is given as 12+18+12+6=
48cm.
