Answer:

x = \frac{25}{7}

Step-by-step explanation:

Using the midline theorem

A segment joining the midpoints of 2 sides of a triangle ia

Parallel to the third side and half the length of the third side, thus

7x - 1 = 24 ( add 1 to both sides )

7x = 25 ( divide both sides by 7 )

x = \frac{25}{7}

Find volume
volumecone=(1/3)(h)(pi)(r^2)

hemisphere is just a half sphere aka, 1/2 times volume of sphere so
hemisphere=(1/2)(4/3)(pi)(r^3)

fnd their volumes don't evaluate the true value till end, leav pi as pi
(or use pi key for graphing or scientific calculators)


cone
d/2=r
10/2=r=5
h=15
V=(1/3)(15)(pi)(5^2)
V=(5)(pi)(25)
V=125pi

hemisphere
V=(1/2)(4/3)(pi)(5.5^3)
V=(4/6)(pi)(166.375)
V=110.91666666666666666pi

which is bigger
125pi or 110.916666666666666666pi
125 pi
by how much?
125pi-110.91666666666666pi=14.08333333333pi
aprox pi=3.14
14.08333333*3.14=44.2217

What is the x-intercept of the line with this equation −2r+1/2 y=18?
Anon25 [30]
To find the x int, we will sub in 0 for y and solve for x...um...r

- 2r + 1/2y = 18
-2r + 1/2(0) = 18
-2r = 18
r = -18/2
r = -9

so the x int is (-9,0)

A local hamburger shop sold a combined total of 605 hamburgers and cheeseburgers on Friday. There were 55 more cheeseburgers sol
Zinaida [17]
H + c = 605
c = h + 55

h + h + 55 = 605
2h + 55 = 605
2h = 605 - 55
2h = 550
h = 550/2
h = 275 <== there were 275 hamburgers sold on Friday

c = h + 55
c = 275 + 55
C = 330...there were 330 cheeseburgers sold on Friday

Compare -1.96312... and negative square root of 5
e-lub [12.9K]
I think it’s right, sorry if I’m wrong...


The square root of 5 is the positive real number that, when multiplied by itself, gives the prime number 5. It is more precisely called the principal square root of 5, to distinguish it from the negative number with the same property. This number appears in the fractional expression for the golden ratio. It can be denoted in surd form as:

It is an irrational algebraic number.[1] The first sixty significant digits of its decimal expansion are:

which can be rounded down to 2.236 to within 99.99% accuracy. The approximation
