Answer:
8x(10)^9 - 2 x (10)^1
1x(10)^3 - 9 x (10)^2
Step-by-step explanation:
3.1 X (10)^4- 6.5 X (10)^2
= 31000- 650
= 30,350
For greater number
_x10^blank - _ x 10^_
8x(10)^9 - 2 x (10)^1 ( we use 9 as the power because greater number used as power gives the bigger number and the next smaller number 8 as base. Similarly we use smaller number for power to get a smaller for the greatest difference)
= 8,000,000,000 -20
= 7,999,999,980
For smaller number
_x10^blank - _ x 10^_
1x(10)^3 - 9 x (10)^2 ( we use 3 as the power because smaller number used as power gives the smaller number and the next smallest number 1 as base. Similarly we use next smaller number for power to get the next smaller for the smallest difference)
= 1000- 900
= 100
We fill in the blanks keeping in mind that we do not have to repeat the numbers from 1-9 and also the numbers should have such an arrangement that they show the smallest and largest possible differences.
If correct will mark brainliest!!!!
What's the question--?
The area of a rectangle is equal to its perimeter. The base of the rectangle is 10 cm. The height of the rectangle is x cm. What is the value of x in this situation?
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

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.

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

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.)

➡️ 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

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,

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°
