Answer:
[-8, 8]
Step-by-step explanation:
The domain is the x values that the equation/line covers.
The line starts at -8 and ends at 8. We use brackets instead of parenthesis since the circles are closed and not open.
find the curved surface area of a cylindrical tank of base radius 30 cm and height 2m
Answer:
37 700m² (rounded off to 3 s.f.)
Step-by-step explanation:
When the curved surface area of a cylindrical tank is laid out, it will be like a rectangular piece of sheet with the circumference of the base circle as its length and the height as its breadth.
Circumference of base circle with radius 30cm = pi × 30 × 2
= 60pi
2m = 200cm
Curved surface are = 60pi × 200
= 12 000pi
= 37 700m² (rounded off to 3 s.f.)
[tex]{\pink{\underline{\textsf{\textbf{Answer : }}}}}[/tex]
➡️ 37,680m² will be the curved surface area of the cylindrical tank.
[tex]{\purple{\underline{\textsf{\textbf{Explanation : }}}}}[/tex]
Given that, A cylindrical tank of base radius is 30cm and it's height is 2m or, 200cm
We need to find the curved surface area
We know that,
➩ Curves surface area of a cylinder = 2πrh
r (radius) = 30cm.
h (height) = 200cm.
Therefore,
➩ Curves surface area of a cylinder:
➩ 2 × 3.14 × 30 × 200
➩ 2 × 18,840
➩ 37,680 m² ans.

whats the unit rate of 5.76
Answer:
there is no unit rate but hers an example of an unit rate using 5.76 NOT THE ANSWER
Step-by-step explanation:
Example: 64 ounces of water in a bottle that costs $5.76. To find the unit rate per ounce, divide the amount it costs ($5.76) by the number of ounces (64). $5.76 ÷ 64 ounces = $0.09 per ounce

hcf and lcm of 120 and 180, shown your work
The HCM and LCM of 120 and 180 are 360.
What is HCF and LCM?The Highest Common Factor (HCF) of two or more given numbers is the largest number that divides each of the given numbers without leaving any remainder. The Least Common Multiple (LCM) of two or more numbers is the smallest of the common multiples of those numbers.
Given are two numbers as -
120 and 180
We can write 120 and 180 as -
120 = 2 x 2 x 2 x 3 x 5
180 = 2 x 2 x 3 x 3 x 5
HCF of 120 and 180 will be equal to = 2 x 2 x 3 x 5 = 60
Now, we can find LCM using the formula -
LCM(a, b) = (a x b)/HCF(a, b)
LCM(a, b) = (120 x 180)/60
LCM(a, b) = 2 x 180 = 360
Therefore, the HCM and LCM of 120 and 180 are 360.

if triangle ABC and DEF are congruent, what is the measure of angle E?
Answer: 83
Step-by-step explanation: Because the triangles are congruent, angle A is congruent to angle D, angle C is congruent to angle F, and angle E is congruent to angle B (CPCTC). Now because angle A and D are congruent they are both equal to 50. Using sum of angles in a triangle, you can find that measure of angle E is equal to 180- (47+50). That is 180-97=83.
Answer:
∠ E = 83°
Step-by-step explanation:
Since the triangles are congruent then corresponding angles are congruent.
Thus ∠ C = ∠ F = 47° and
∠ B = 180° - (50 + 47)° ← angle sum of Δ
∠ B = 180° - 97° = 83°
∠ B and ∠ E are corresponding angles, thus
∠ E = ∠ B = 83°

20 POINTS N BRAINLIEST!!16.Alun has a part-time job working as a bus boy at a
local restaurant. He earns $34 a night plus 5% of
the tips.
a) Write an equation for Alun's total earnings,
E dollars, when the tips are t dollars.
b) What will Alun earn when the tips are $400?
Explain your strategy.
c) What were the nightly tips when Alun earned
$64? Explain your strategy.
Answer:
a)E=.05t +34
b)$54
c)$600
Step-by-step explanation:
a) he gets 5% of tips out of all tips people gave to the restaurant , 5% --> .05 (as a decimal) --> this is "t"
he earns an extra $34 a night of work. --> this is the constant
E= --> the total earned that night
E=.05t +34
b) simply plug in the total tip into the equation
E=.05(400) + 34
E=$54
--> he earned $54 that night
c) since we are given the total earned that night, we now plug in for y. in this case we plug "$64" for y
we find t, which is tip the restaurant was given
--> 64 = .05t +34
-34. -34
30= .05t ---> divide by .05 each side
t= $600
the restaurant was tiped 600 dollars and Alun was paid 64 dollars that night of work
hoped this helped:)

Step-by-step explanation:

XY is tangent at P and CP is radius
[tex] \therefore CP\perp XP\\(\because tangent\: is \: perpendicular \: to\: radius) \\\\
\therefore m\angle CPX = 90\degree \\[/tex]
4.
Radius of the circle = diameter /2 = 13/2 = 6.5.cm
5.
For BD to be be tangent to the circle with center C, BD should make right angle with radius CB.
[tex] AD^2 [/tex] should be equal to the sum of the squares BD and AB.
Let us work it out:
[tex] AD^2 = 7^2 = 49....(1)\\
AB^2 + BD^2 = 5^2 +5^2 \\
AB^2 + BD^2 = 25 + 25 \\
AB^2 + BD^2 = 50....(2) \\[/tex]
From equations (1) & (2), it is obvious that:
[tex] AD^2 \neq AB^2 + BD^2[/tex]
So, BD is not tangent to the[tex] \odot\: C. [/tex]
6.
Tangents drawn from an external point to a circle are congruent.
In circle with center C, BA and BD are tangents drawn from external point B.
Therefore,
BA = BD
x = 4
7.
In circle with center C, BA and BD are tangents drawn from external point B.
Therefore,
BD = BA (tangents drawn from external point to a circle)
x = 2
8.
In circle with center C, BA and BD are tangents drawn from external point B.
Therefore,
BA = BD (tangents drawn from external point to a circle)

24 in.
Answer: PN= 20 in.
Step-by-step explanation:
Given: In triangles PMN and QSR :
Length of P N ≅ Length of RQ (1) [ '≅' → Sign of congruence]
Length of QS ≅ Length of PM
Length of MN ≅ Length of RS
By SSS congruence rule
ΔPMN ≅ ΔQSR
Since Length of QR =20 in. [Given]
From (1)
Length of PN= 20 in. [Congruent means exactly equal]

x=
Answer:
10x
Step-by-step explanation:
a=p
base=10
height=x
area=10 times x
perimeter=10+10+x+x
to work out area you times the base (10) by the height however since the height is x in this instant the answer is 10 times x which simplifies to 10x
