When you're multiplying fractions by a whole number, flip the equation around. For the first one, ?/2x8=4 can be converted to 8/2=4. Or half of 8 is 4.
The next one is missing the whole number. It converts to 20/6 / 5/6, which is equal to 20/5 and 6/6, which is 4/1 or 4.
The last question can be converted to 18/3=?, which is 6. So the answer to that one is 1/6 x 18=3.
1. 1/2 x 8 = 4
2. 4 x 5/6 = 20/6
3. 1/6 x 18 = 3

A quartic polynomial P(x) has rational coefficients. If 2 − i and-√5 are roots of P(x) = 0, what are the other 2 roots?
Answer:
2 + i and + √5
Step-by-step explanation:
Since P(x) is a quartic equation, it has 4 roots.
Since 2 - i and -√5 are two of its roots, then its conjugate pairs of 2 + i and + √5 are its other two roots.
So, its other two roots are 2 + i and + √5

In ΔFGH, the measure of ∠H=90°, the measure of ∠G=52°, and GH = 5.7 feet. Find the length of FG to the nearest tenth of a foot.
Answer:
FG = 9.3 feet
Step-by-step explanation:
cos 52° = 5.7/FG
0.6157 = 5.7/FG
FG = 9.26 feet

PLS HELP ME ASAP! The height and width of a rectangular prism are 26 yards and 24 yards respectively. Find the length of the
rectangular prism whose volume is 18,720 cubic yards.
Answer:
The length is 30 cubic yards.
Step-by-step explanation:
To find volume you use equation V=LxWxH
Since we already know the height, width, and volume we can input them into the equation.
18,720=L x 24 x 26
As you can see, the length is still unknown.
To figure it out though, you can multiply the height and width of the prism,
24 x 26 = 624
And then divide the volume, 18,720 by it.
18,720/624 = 30
Thus, your length is 30 cubic yards.

Find the volume of the cone-
Answer:
12.6ft³
Step-by-step explanation:
Hey There!
So the first thing we need to do is find the formula for volume of a cone
[tex]V=\pi r^{2} \frac{h}{3}[/tex]
r = radius
h = hypotenuse
Now all we have to do is plug in the hypotenuse and the radius
[tex]V=\pi 2^{2} \frac{3}{3}[/tex]
2²=4
[tex]\frac{3}{3} =1[/tex]
4xπ=12.5663706144
And now we just round to the nearest tenth
so we can conclude that the volume of the cone is 12.6ft³
Can someone please help me
Answer:
20 ft
Step-by-step explanation:
Keep in mind that, both ratios are the same, let the length of the shadow be x, then you can make an equation that 30/ 40 = 15 / x, then 30x = 15 * 40 = 600, so x = 20.
Use the information to solve the triangle. Round your answers to two decimal places. Hint: draw a sketch first to determine if you should use Law of Sines or Cosines.
B=100°, a=15, b=23
Answer:
A = 40.0 (3 sig. fig)
C = 40
c = 15
Step-by-step explanation:
Using sin law,
sinA/15 = sin100/23
A = 40.0 (3 sig. fig)
Using angle sum of triange,
C = 180 - 40.0 - 100 = 40
Since angleA = angleC, by side equal opp angles, c = 15

Mary took a math test and she got four questions incorrect and 21 correct. What percent did answer correctly?
Answer:
84%
Step-by-step explanation:
21 correct + 4 wrong = 25 questions in total
[tex]\frac{21}{25}[/tex] x 4 = [tex]\frac{84}{100}[/tex]
[tex]\frac{84}{100}[/tex] = 0.84
0.84 = 84%

5/8 ÷ 3/8 = ab/c
Answer:
a = 1, b = 2, and c = 3
Step-by-step explanation:
5 ÷ 8 ÷ 3 ÷ 8
5 ÷ 8 × 8 ÷ 3
The 8 cancels out.
5 ÷ 3 or 5/3
5/3 = 1 and 2/3

The circumference of a circle is 147 feet.
Find the area of the circle, in terms of pi.
Answer:
Step-by-step explanation:
C = 147 ft. The relevant formula is C = 2(pi)r, and here C = 147 ft = 2(pi)r.
The relevant area formula is A = (pi)r^2. If we solve the above formula for r we get
147 ft
r = ------------ and so r^2 (needed to calculate the area) is
2pi
147^2 ft^2
r^2 = ------------------
4(pi)
147^2 ft^2
and so the area is A = ---------------- = 7203/pi
3 pi
C C^2
Alternative method: C = 2pi*r so r = -------------- and r^2 = -------------
2 pi 4pi^2
C^2 C^2
then the area of the circle is A = pi(r^2) or pi*-------------- = ---------------
4pi^2 4pi
(147 ft)^2
and in this case the area of the circle is A = --------------
4 pi
or A = 1720 ft^2

An artist sold 10 paintings. Her first two sold for $50 and $350. She sold three at a gallery show for $250, $400 and $1,200. She sold her oil paintings on line for $410, $400 and $375. Family members bought two, one for $200 and another for $280. What is the IQR of the selling price of her paintings?
Answer:
250-400
Step-by-step explanation:
Answer:
150Step-by-step explanation:
There are 10 numbers representing the selling prices of paintings.
List the numbers in the ascending order:
50, 200, 250, 280, 350, 375, 400, 400, 410, 1200Median of the lower half is:
50, 200, 250, 280, 350 ⇒ Q1 = 250Median of the upper half is:
375, 400, 400, 410, 1200 ⇒ Q3 = 400The IQR is the difference between the upper and lower medians:
IQR = Q3 - Q1 = 400 - 250 = 1500.177 ? 0.67
