can anyone fill the blanks?
Answer:
see below
Step-by-step explanation:
2/5 + 1/3 + x = 1
Get a common denominator of 15
2/5 * 3/3 + 1/3 *5/5 +x = 1
6/15 + 5/15 +x = 1
11/15 + x = 1
Subtract 11/15 from each side
11/15 +x-11/15 =15/15-11/15
x = 4/15

What 2 decimal place number lies between 4.174 and 4.189 ?
what could be the answer to my question in my maths work : 4.5 x 0.2
im struggling with this :D i need help!
Answer:
not a real number
Step-by-step explanation:
any negative number under a square root sign, except for 0, isn't real
On evaluating the given roots,
(a) [tex]$-(\sqrt[3]{8}) = -2$[/tex]
(b) [tex]$\sqrt[4]{-81}$[/tex] is not a real number
(a) [tex]$-(\sqrt[3]{8})$[/tex]:
The cube root of 8 is the number that, when raised to the power of 3, equals 8. In this case, the cube root of 8 is 2, because [tex]2^3 = 8[/tex].
Since we have a negative sign in front of the cube root, the result will be the negative value of the cube root of 8.
Therefore, [tex]$-(\sqrt[3]{8}) = -2$[/tex].
(b) [tex]$\sqrt[4]{-81}$[/tex]:
The fourth root of a number is the number that, when raised to the power of 4, equals the given number.
In this case, we are looking for the fourth root of -81.
However, the fourth root of a negative number is not a real number. This is because raising a positive number to an even power (in this case, 4) will always result in a positive value, and there is no real number that, when raised to the power of 4, gives a negative result.
Therefore, the fourth root of -81 is not a real number.

Colin buys a tv for £800. It depreciates at a rate of 1% per year. How much will it be worth in 2 years? Give your answer to the nearest penny where appropriate
Answer: £784.08
Step-by-step explanation:
First find 1% of 800, which is 800/100=£8
800-8= £792 after 1 year
find 1% of 792, which is 792/100=£7.92
792-7.92= £784.08

Each sheep has 4 legs and each chicken has 2 legs.if a farm boy counts 50 heads and 130 feet, how many sheep are there
Answer:
15 sheep
Step-by-step explanation:
1 leg = 1 foot
1 head = 1 animal
Suppose all the animals are chickens:
50 × 2 = 100
130 - 100 = 30
4 - 2 = 2
30 ÷ 2 = 15
Hence, there are 15 sheep.
Quinn leaves her house at 10:00 am and runs 3 miles at a steady pace of 6 miles per
hour. She relaxes and takes a lunch break for 1 hour. She is pretty tired so she walks
home at a steady pace of 2 miles per hour. What time does Quinn return home
Using the relation between velocity, distance and time, it is found that Quinn returns home at 1 pm.
Velocity is distance divided by time, that is:
[tex]v = \frac{d}{t}[/tex]
She walked 3 miles at a velocity of 6 miles per hour, thus [tex]d = 3, v = 6[/tex]. The time is:[tex]v = \frac{d}{t}[/tex]
[tex]t = \frac{d}{v} = \frac{3}{6} = 0.5[/tex]
Thus, she arrived at 10:30 am, and took a lunch break of 1 hour, so she started to return at 11:30 am.Distance of 3 miles, velocity of 2 miles per hour, thus [tex]d = 3, v = 2[/tex]. The time she took to return, in hours, is:[tex]t = \frac{d}{v} = \frac{3}{2} = 1.5[/tex]
1.5 hours after 11:30 am is 1 pm, thus, Quinn returns home at 1 pm.

-7+ 3x-2(3x+4)= 5(2x-3) + 4 (3x - 1) - 4.
Answer:
[tex] - 7 + 3x - 2(3x + 4) = 5(2x - 3) + 4(3x - 1) - 4 \\ - 7 + 3x - 6x - 8 = 10x - 15 + 12x - 4 - 4 \\ - 3x - 15 = 22x - 15 - 8 \\ 25x = 8 \\ x = \frac{8}{25} [/tex]
Show all work to identify the asymptotes and zero of the function f of x equals 4 x over quantity x squared minus 16.
9514 1404 393
Answer:
asymptotes: x = ±4, y = 0zero: x = 0Step-by-step explanation:
The function factors as ...
[tex]f(x)=\dfrac{4x}{(x-4)(x+4)}[/tex]
The vertical asymptotes are found where the denominator factors are zero:
x-4 = 0 ⇒ x = 4
x+4 = 0 ⇒ x = -4
The zero of the function is where the numerator is zero:
4x = 0 ⇒ x = 0
The horizontal asymptote of the function is the value of 4x/x² when x tends to infinity. That value is zero. The equation of the horizontal asymptote is ...
y = 0

Answer:
x = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
The opposite sides of a rectangle are congruent , then
10x - 1 = 4x + 2 ( subtract 4x from both sides )
6x - 1 = 2 ( add 1 to both sides )
6x = 3 ( divide both sides by 6 )
x = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex] ( = 0.5 )
