Answer:
12%
Step-by-step explanation:
As per the provided information in the given question, we have :
Original price of petrol = Rs. 48New price of petrol = Rs. 53.76We are asked to calculate,
Percentage increaseAs we know that,
[tex] \\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( \dfrac{Price \; increase}{Original \; price} \times 100 \Bigg ) \; \%}} \\ [/tex]
→ Price increase = New price - Original price
→ Price increase = Rs. ( 53.76 - 48 )
→ Price increase = Rs. 5.76
Substituting values,
[tex] \\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( \dfrac{5.76}{48} \times 100 \Bigg ) \; \%}} \\ [/tex]
[tex] \\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( \dfrac{576}{4800} \times 100 \Bigg ) \; \%}} \\ [/tex]
[tex] \\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( \dfrac{57600}{4800} \Bigg ) \; \%}} \\ [/tex]
[tex] \\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( \dfrac{576}{48} \Bigg ) \; \%}} \\ [/tex]
[tex] \\ \longrightarrow \bf{\quad\underline { \% \; increase = 12\; \%}} \\ [/tex]
Therefore, percentage increase is 12 %.
What is the product of 3.8\times 10^23.8×10
2
and 6.4 \times 10^66.4×10
6
expressed in scientific notation?
Answer:
2.432 * 10⁹
Step-by-step explanation:
Given the expression;
3.8*10² × 6.4*10⁶
= (3.8*6.4)× (10²*10⁶)
= 24.32*10⁸
= 2.432* 10¹ * 10⁸
= 2.432 * 10⁹
Hence the product expressed as a scientific notation is 2.432 * 10⁹
4) What is the domain of the function?
Please help
Answer:
-4 <= x <= 5.
Step-by-step explanation:
For the end points, we usually colour it same as the ink, in blue, to mean inclusion. Here it is red, but we will assume inclusion as well, since exclusion will not have any correct answer.
Domain consists of all the valid values of x that apply to the function, which is from -4 to 5 inclusively. We will not exclude non-integer values because this is what the graph indicates.
The only valid answer is therefore the first one, -4 <= x <= 5.

4 × ( 4 + 9 ) = 2 × ( 2 + x )
4 × 13 = 2 × ( 2 + x )
2 × 2 × 13 = 2 × ( 2 + x )
2 × 26 = 2 × ( 2 + x )
Divide both sides by 2
2 × 26 ÷ 2 = 2 × ( 2 + x ) ÷ 2
26 = 2 + x
Subtract both sides 2
26 - 2 = 2 - 2 + x
x = 24

What is the equation of the line that passes through (3.-1) and is parallel to the line y = 3x + 2?
Answer:
[tex]y=3x-10[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)Parallel lines always have the same slope and different y-intercepts1) Determine the slope (m)
[tex]y = 3x + 2[/tex]
From the given line, we can identify clearly that 3 is in the place of m, making it the slope. Because parallel lines have the same slope, the line we're solving for will also have a slope of 3. Plug this into [tex]y=mx+b[/tex]:
[tex]y=3x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=3x+b[/tex]
Plug in the given point (3,-1)
[tex]-1=3(3)+b\\-1=9+b[/tex]
Subtract 9 from both sides
[tex]-1-9=9+b-9\\-10=b[/tex]
Therefore, the y-intercept of the line is -10. Plug this back into [tex]y=3x+b[/tex]:
[tex]y=3x-10[/tex]
I hope this helps!

Answer:
The answer is "[tex](x + 8)^2 = 58[/tex]"
Step-by-step explanation:
Let the equation is:[tex]x^2+16x=-6[/tex]
by adding and subtracting 64 then:
[tex]x^2 + 16x + 64 = -6 + 64\\\\x^2 + 2\times x\times 8 + 64 = -6 + 64\\\\ (x + 8)(x + 8) = 58\\\\ (x + 8)2 = 58[/tex]
the cost to go bowling is a function in terms of the number of games bowled. the cost to bowl 2 games with a shoe rental is $16.50. the cost to bowl 4 games with a shoe rental is $28.50. what is the cost of renting shoes?
Answer:
x = cost of games bowled = $6
y = cost of shoe rental = $4.50
Step-by-step explanation:
Let
x = cost of games bowled
y = cost of shoe rental
2x + y = 16.50 (1)
4x + y = 28.50 (2)
Subtract (1) from (2) to eliminate y
4x - 2x = 28.50 - 16.50
2x = 12
x = 12/2
x = 6
Substitute x = 6 into (1)
2x + y = 16.50 (1)
2(6) + y = 16.50
12 + y = 16.50
y = 16.50 - 12
y = 4.50
x = cost of games bowled = $6
y = cost of shoe rental = $4.50

Solve for x Show your work
Answer:
x = 12
Step-by-step explanation:
To solve this and show your work, you have to start of with the equation (3x - 6) = 30.
You then have to add 6 to both sides like this:
[tex](3x - 6) = 30 \\ \: \: \: \: \: \: \: \: \: \: + 6 \: \: \: \: \: + 6 [/tex]
So then the 6 is cancelled out, and you are left with
3x = 36.
Now you just have to divide both sides by 3 like this:
[tex] \frac{3x}{3} = \frac{36}{3} [/tex]
Which cancels 3 out, and you are left with
x = 12.
Find the value of x, when log 10x + log 2 = log 60
Answer:
x = 3
Step-by-step explanation:
log 10x + log 2 = log 60
Subtract log 2 from each side
log 10x + log 2 -log 2 = log 60 - log 2
log 10x = log 60 - log 2
We know that log a - log b = log (a/b)
log 10 x = log (60/2)
log 10x = log 30
We know log a = log b that a = b
10x = 30
Divide by 10
10x/10 = 30/10
x =3

Hari's weekly allowance varies depending on the number of chores he does. He received $24 in allowance the week he did 16 chores, and $18 in allowance the week he did 4 chores. Write an equation for his allowance in slope-intercept form.
i need help!
Answer:
y = (1/2)x + 16
Step-by-step explanation:
General point/slope form is
y = mx +b (the two points given are (4,18) and (16,24))
slope = rise/run = (24-18)/(16-4) = 6/12 = 1/2
y = (1/2)x + b
pick one point (4,18) and plug in
18 = (1/2)4 + b
18 = 2 + b
b = 16 (he still gets $16 for zero chores)
So
y = (1/2)x + 16
Write an equation of the line with slope -1 passing through (8,5).
Answer:
y = -1x + 13
Step-by-step explanation:
y = -1x + b
5 = -1(8) + b
5 = -8 + b
13 = b

Is 2.99 irrational or rational?
Answer:
rational
Step-by-step explanation:
its decimal expansion terminates after 9 and it can also be represented as fraction.
Answer:
Rational
Step-by-step explanation:
Irrational numbers are numbers that cannot be written as a fraction (denominator of 1 does not count). 2.99 can easily be written as a fraction (e.g. [tex]\frac{299}{100}[/tex]) and therefore is rational.
What is the value of angle vux
==============================================
There are two ways to do this.
The quicker way is to use the remote interior angle theorem. We have the interior angles 53 and 103 which add to 53+103 = 156 which is exactly the exterior angle VUX.
---------------
The slightly longer way involves finding angle TUV first. Let's say this is equal to the variable y
Adding any three interior angles of a triangle always gets us 180
53+103+y = 180
y+156 = 180
y = 180-156
y = 24
Angle TUV is 24 degrees
The angle supplementary and adjacent to this is angle VUX, which I'll call z
z+y = 180
z = 180-y
z = 180-24
z = 156
So this is another way to get to the answer 156 degrees.

The school cafeteria sells two kinds of wraps: vegetarian and chicken. The vegetarian wrap costs $1.00 and the chicken wrap costs $2.70. Today they made $244.60 from the 146 wraps sold. How many of the wraps sold were vegetarian?
Answer:
88 Vegetarian Wraps Sold.
Step-by-step explanation:
This is a System of Equations Problem.
Your Two Systems Are:
v(1)+c(2.7)=244.6 and c+v=146
c = chicken wraps and v = vegetarian wraps
Each chicken wrap costs $2.70 (2.7). Put the variable of c next to (2.7) meaning to multiply.
Each vegetarian wrap costs $1 (1). Put the variable of v next to (1)
244.60 (244.6) is the total amount of money made from selling the wraps. This will be the total of the equation.
v(1)+c(2.7)=244.6
Solve 2.7c+v=244.6 for v.
Add -2.7c to both sides.
2.7c+v+−2.7c=244.6+−2.7c
v=−2.7c+244.6
Substitute −2.7c+244.6 for v in c+v=146.
c+v=146
c+−2.7c+244.6=146
Simplify both sides of the equation.
−1.7c+244.6=146
Add -244.6 to both sides.
−1.7c+244.6+−244.6=146+−244.6
−1.7c=−98.6
Divide both sides by -1.7.
[tex]\frac{-1.7c}{-1.7} =\frac{-98.6}{-1.7}[/tex]
c=58
Substitute 58 for c in v=−2.7c+244.6.
v=−2.7c+244.6
v=(−2.7)(58)+244.6
Simplify both sides of the equation.
v=88
Answer:
c=58 and v=88
