Which figure does NOT belong?

Answer:

Step-by-step explanation:
The spirals in the first, second, and fourth figures are all clockwise from the outer end, i.e., if you trace these three spirals with your finger from the outside to the inside, your finger will move clockwise.
However, if you did the same with the third figure, you would see that the spiral is anti-clockwise from the outside moving in.

A parallelogram has sides of length 16 units and 10 units. The shorter diagonal is 11 units. Find the measure of the longer diagonal. Round to 2 decimal places, if necessary.
Answers
The measure of the longer diagonal is 24.31 units
How to determine the longer diagonal?The side lengths are given as;
a = 16
b = 10
The shorter diagonal is represented as d1, and it is given as
d1 = 11
The longer diagonal is represented as d2, and it is calculated using
d1^2 + d2^2 = 2 * (a^2 + b^2)
Substitute the known values in the above equation
11^2 + d2^2 = 2 * (16^2 + 10^2)
Evaluate the sum
121 + d2^2 =2 * 356
Evaluate the product
121 + d2^2 = 712
Subtract 121 from both sides
d2^2 = 591
Take the square root of both sides
d2 = 24.31
Hence, the measure of the longer diagonal is 24.31 units

Answers
The percentage yield of carbonic acid is 66 percent.
How to find percentage yield?The percentage yield of the carbonic acid can be found as follows:
NaHCO₃ → Na₂CO₃ + H₂CO₃
Hence, 2.36g sample of NaHCO₃ was thermally decomposed to generate 1.57g of carbonic acid (H₂CO₃)
Using law on conservation, the mass of the reactant is equals to the product.
Therefore,
percentage yield of carbonic acid = 1.57 / 2.36 × 100

Fatima purchased a new mattress when it was on sale. The sale price was 34% less than the regular price. If the sale price was $371, what was the original price? (Round your answer to the nearest dollar).
Answers
Answer:
$580
Step-by-step explanation:
{371x(100-34)/100}+371=580
The original price (rounded to the nearest dollar) is $497.
Explanation:In this problem, we need to identify what's the original price of the new mattress.
Since we know that the sale price is $371 and is 34% lesser than the original price, we need to add 371 and 34%.
Grab a calculator and add 371 and 34%
we get:
371 + 34% = 497.14
Now round it to the nearest whole number, we get: 497

Answers
6.665 grams of the 13 grams remain after 8 hours.
How much of a 13 gram sample of iron-52 would remain after 8 hours?The decay equation for the 13 grams of iron-52 is:
[tex]N(t) = 13g*e^{(-ln(2)/8.3h)*t}}[/tex]
Where N is the amount of iron-52, and t is the time in years.
Where we used the fact that the half-life is exactly 8.3 hours.
Now, the amount that is left is given by N(8h), so we just need to replace the variable t by by 8 hours, so we get:
[tex]N(8h) = 13g*e^{(-ln(2)/8.3h)*8h}} = 6.665g[/tex]
So 6.665 grams of the 13 grams remain after 8 hours.

A box has 1 red marble, 3 blue marbles, and 4 green marbles. Maya draws a blue marble randomly from the box, replaces it, and then draws another marble randomly. What is the probability of drawing 2 blue marbles in a row? Explain
Answers
Step-by-step explanation:
there are
1 red marble
3 blue marbles
4 green marbles
in the box.
that means there are 8 marbles in the box. which gives us 8 different outcomes for pulling randomly 1 marbles.
the probability for each of these 8 outcomes is equal : 1/8.
remember, the probability is always the number of desired cases over the number of total possible cases.
so, the probability of pulling a red marble is :
1 desired case
8 total cases
->
1/8 or 0.125
the probability of pulling a blue marble is :
3 desired cases
8 total cases
->
3/8 or 0.375
the probability of pulling a green marble is :
4 desired cases
8 total cases
->
4/8 = 1/2 or 0.5
now the experiment is pulling 2 marbles in a row, but the first pulled marble is put back into the box again.
this makes this a combined event, where the first AND the second event must fulfill the desired over total cases.
if the 2 events are independent (not overlapping or influencing each other), then we can simply multiply the probabilities. which is the case here, because the first marble is put back.
why ?
because now we have 8 possible outcomes for the first ball, and again 8 possible outcomes for the second ball, and when we combine all possibilities from the first with all possibilities from the second pull, we get 8×8 = 64 possible outcomes :
red. red
red. blue1
red. blue2
red. blue3
red. green1
...
green4 green4
so, the probability to pull a blue ball first is
3/8
and the probability to pull a blue ball second is
3/8 too
the combined probability of the combined event is
3/8 × 3/8 = 9/64
we have 3×3 = 9 desired outcomes of combining 3 blue and 3 blue balls out of the total of 64 possible outcomes.

Circle B has a radius of 24 units, Circle E has a radius of 9 units, and segment CD = 4. Find segment A.F. Round your answer to the nearest tenth.
Answers
The length of segment A.F in the circles given is: 62 units.
What is the Radius of a Circle?A radius of a circle is half the diameter of a circle, which is a point from the center to any point on the circumference of the circle. This implies that any segment that is drawn from the center of a circle to any point on the circumference of a circle is a radius. Also, all radii of a circle are always congruent to each other.
Radius of circle B = AB = BD = 24 units [all radii of a circle are congruent to each other].
Radius of circle E = CE = EF = 9 units [all radii of a circle are congruent to each other].
CD = 4
DE = x
CD + DE = CE
Plug in the values into the equation
4 + x = 9
x = 9 - 4
x = 5
DE = 5
The length of segment DE is 5 units
A.F = AB + BD + DE + EF
Plug in the values into the equation
A.F = 24 + 24 + 5 + 9
A.F = 62 units.

Hence, the velocities are given as follows:
a. v(8000) = 0.12879 x 8000 + 121.03448 = 1151 km/h.
b. v(3500) = 0.12879 x 3500 + 121.03448 = 572 km/h.
c. v(70) = 0.12879 x 70 + 121.03448 = 130 km/h.
d. v(5) = 0.12879 x 5 + 121.03448 = 122 km/h.

which theorem can be used to show that LJKL is the same as LMNP
a. AA similarity
b. SSS similarity
c. ASA similarity
d. SAS similarity
Answers
Reason
In two triangles, if two pairs of corresponding angles are congruent, then the triangles are similar . (you can find the congruent missing angles using the Angle Sum Theorem, all three angles add up to 180.)
Note: SSS is three congruent sides, ASA is angle side angle congruent with an included side and SAS is side angle side, none of these are true for this figure

Answers
Say you have a quadrilateral ABCD where angles A and C are 90. In quadrilaterals, consecutive angles are supplementary. This means A + B = 180 and C + D = 180. If A and C are 90, then B and D must be 90.
Either all 4 angles are right or no angles are right
