Answer:
[tex]\sqrt{59}[/tex]
Step-by-step explanation:
7^2 is 49 and 8^2 is 64, which means the square root of any number between 49 and 64 (exclusive) will be in between 7 and 8, and it's also going to be irrational, because it's not a perfect square.
One number between 49 and 64 is 59, so [tex]\sqrt{59}[/tex] is an irrational number between 7 and 8
Calculate the density of benzene if 0.10L has a mass of 36.4g.
Answer:
[tex]d=0.364\ g/cm^3[/tex]
Step-by-step explanation:
It is given that,
Mass of benzene, m = 0.1 L
Mass, m = 36.4 g
We know that, 1 L = 1000 cm³
0.1 L = 100 cm³
The density of an object is equal to its mass divided by its volume. So,
[tex]\rho=\dfrac{m}{V}\\\\=\dfrac{36.4\ g}{100\ cm^3}\\\\=0.364\ g/cm^3[/tex]
So, the density of benzene is [tex]0.364\ g/cm^3[/tex].

sam eats 1/4 of a pizza joe eats 1/2 of the remaining pizza. what part of the original pizza is left?
Answer:
1/4 of the pizza is left
If Sam eats 1/4 of the pizza, we must subtract 1/4 from 1.
1 - 1/4 = 3/4.
Now, Since Joe eats 1/2 of the pizza, we subtract 2/4, since 1/2 = 2/4.
3/14 - 2/4 = 1/4.
Answer = 1/4

Answer:
They will break even... but im not 100% sure im correct
Step-by-step explanation:
Im not 100% sure but here is what i have...
based on the given inequality the new one would be 15n>105+4.50n,
First subtract the 4.50n from the right side of the inequlaity sign.
Now you should have 10.5n>105
second, plug in a random number to see if she will make money or not..
I used 10, so plug 10 in for "N".
it will look like this, 10.5(10)>105
now do the math and get, 105>105,
which brings me to the cunclution she breaks even..

If x is direct proportional to y cube and x=32 when y=2
1. Find the value of x when y=6
2. Calculate the value of y when x=108
Answer:
1x=864,
2y=3
Step-by-step explanation:
y=6,x=?
if x is directly proportional to y^3 &if (when x=32, y is=2) we can understand that x=4y^3
1,x=4y^3
x=4(6^3)
x=4(216)
x=864
2,x=4y^3
108=4y^3
108/4=4y^3/4
27=y^3
√27=y
y=3
i think it is easy to understand,but if the answers are not clear you can ask me &i hope it helps you

Find the results of the given vector subtractions for u = <-8, 4> and V = <2,7>.
Answer:
see explanation
Step-by-step explanation:
- u - v
= - < - 8, 4 > - < 2, 7 > ← multiply each component of u by - 1
= < 8, - 4 > - < 2, 7 > ← subtract corresponding elements
= < 8 - 2, - 4 - 7 >
= < 6, - 11 >
----------------------------------------------------------
u - v
= < - 8, 4 > - < 2, 7 > ← subtract corresponding elements
= < - 8 - 2, 4 - 7 >
= < 6, - 3 >
-----------------------------------------------------------
v- u
= < 2, 7 > - < - 8, 4 > ← subtract corresponding elements
= < 2 - (- 8), 7 - 4 >
= < 2 + 8, 7 - 4 >
= < 10, 3 >

Producing a musical cost $88,000 plus $5,900 per performance. One sold-out performance earns $7,500 in revenue. If every performance sells out, how many performances are needed to break even? ( solving and writing Mulit-step equation question)
Answer:
55 performances
Step-by-step explanation:
The first equation will be the total cost. The total cost has $88,000 already and then $5,900 is added with each performance. So the equation would be 88,000+5,900x because x will represent the number of performances.
y = 88,000 + 5,900x
The next equation will be how much the performances earn. If they earn $7,500 with each performance then the equation will be 7,500x, with x representing the number of performances
y = 7,500x
Now set the equations equal to each other and solve for x
7,500x = 88,000 + 5,900x
1,600x = 88,000
x = 55
They need to have 55 performances for the cost and the revenue to break even.

18 ft 27 ft 37 ft What is the area of this trapezoid? square feet
Answer:
832.5.
Step-by-step explanation:
sorry, but this cannot type fractions, so just take the answer.
Answer:
832.5
Step-by-step explanation:
To find the area of a trapezoid, you need to use the formula (a+b)/2 x h
a = 18 = base
b = 27 = base
h = 37 = height
18 + 27 = 45
45/2= 22.5
37 x 22.5 = 832.5

Donna receives a $100 gift card to MovieStop. Her Blu-ray player is able to play both Blu-rays and DVDS, so she would like to get a combination of both. Each Blu-ray cost $25.99 and DVDs cost $15.99 each. Write an equation modeling the number of Blu-rays, b, and DVDs, d, that Donna can purchase with her gift card.
Answer:
100=25.99b+15.99dStep-by-step explanation:
step one:
let the number of Blu-rays be b and
DVDS be d,
step two:
given that Blu-rays cost $25.99each and
DVDS cost $15.99 each,
we can model the cost of the Blu-rays and DVDS, as
100=25.99b+15.99d
hence the expression for the number of Blu-rays and DVDS, is given as
100=25.99b+15.99d

what is -2x + 12 divided by 4
Answer:
x=4
Step-by-step explanation:
First set the equation equal to 4:
-2x +12=4
Subtract 12 from both sides:
-2x +12=4
-12 -12
-2x=-8
Then divide each side by -2 to isolate the x:
-2x/-2=-8/-2
x=4
