Brian pays £475.29 a year on his car insurance.
The insurance company reduces the price by 2.1%.
How much does the insurance cost now?
Give your answer rounded to 2 DP.
Answer:
465.31
Step-by-step explanation:
475.29 - Percentage decrease =
475.29 - (2.1% × 475.29) =
475.29 - 2.1% × 475.29 =
(1 - 2.1%) × 475.29 =
(100% - 2.1%) × 475.29 =
97.9% × 475.29 =
97.9 ÷ 100 × 475.29 =
97.9 × 475.29 ÷ 100 =
46,530.891 ÷ 100 =
465.30891 ≈

Find the equation of a line that passes through the point (3,4) and has a gradient of 4.
Leave your answer in the form y= mx + c
HELP ASAP WIL LGIEV BRANLIEST FOR CORRECT ANSWER
Answer:
y=4x-8
Step-by-step explanation:
Y=mx+c
4=4(3)+c
C=-8
y=4x-8
Step-by-step explanation:
given that gradient i.e. m= dy/dx = 4.
equation passes through point (3,4)...
(Y - y1) = m (X-x1)
Y-4 = 4(X-3)
Y-4 = 4X-12
or Y = 4X-8

No, the equation is not a good fit because the sum of the residuals is a large number.
No, the equation is not a good fit because the residuals are all far from zero.
Yes, the equation is a good fit because the residuals are not all far from zero.
Yes, the equation is a good fit because the sum of the residuals is a small number.

Find the y-intercept of the line 19x - 13y = 26.
Write your answer as an integer or as a simplified proper or improper fraction, not as an
ordered pair.
Answer:
y - intercept = - 2
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
19x - 13y = 26 ( subtract 19x from both sides )
- 13y = - 19x + 26 ( divide terms by - 13 )
y = [tex]\frac{19}{13}[/tex] x - 2 ← in slope- intercept form
with y- intercept c = - 2
The y-intercept of the line equation 19x - 13y = 26 is 2.
Given that, the y-intercept of the line 19x - 13y = 26.
What is a y-intercept?In Maths, an intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.
The given equation can be written in standard form as
13y=19x-26
⇒ y=19/13 x-26/13
⇒ y=19/13 x-2
So, y-intercept =2
Therefore, the y-intercept of the line equation 19x - 13y = 26 is 2.

I need help on this question
Step-by-step explanation:
the area of a rectangle is
length × width.
our job here is to find all integer values for length and width, so that their product is 90.
that means that length and width are both factors of 90.
the factors of 90 are
1 × 90
2 × 45
3 × 30
5 × 18
6 × 15
9 × 10
10 × 9
15 × 6
18 × 5
30 × 3
45 × 2
90 × 1
the prime number grouping
is
2 45 (can't be divided by 2 anymore, so,
next prime factor)
3 15
3 5 (can't be divided by 3 anymore, so
next prime factor)
5 1 (the end)
so, besides 1 and these prime factors, the only other factors are combinations of these prime factors :
2×3 = 6
2×5 = 10
3×3 = 9
3×5 = 15
2×3×3 = 18
2×5×3 = 30
3×5×3 = 45
show that the equation y = 7/3x - 11/8 can be written in the standard form ax + by = c, in which a, b, and c are all integers

[tex]\green{ \underline { \boxed{ \sf{Surface \: area \:of \:Cube = 6a^2}}}}[/tex]
where a is side of the cube[tex]\begin{gathered}\\\quad \sf Surface \: area \:of \:Cube = 6\times(3.2)^2 \\\end{gathered} [/tex]
[tex]\begin{gathered}\\\implies \quad \sf 6\times 3.2\times3.2 \\\end{gathered} [/tex]
[tex]\begin{gathered}\\\implies \quad \sf 61.44 cm^2 \\\end{gathered} [/tex]

At the beginning of Jack's diet, he was 257 pounds. If he lost 3 pounds per week, find his weight after
12 weeks.
Answer:
A loss of weight means we subtract from Jack's current weight.

Maya started to run on a treadmill after setting its timer for 99 minutes. The display says that she has finished 27% of her run. How many minutes have gone by? Round your answer to the nearest tenth. minutes
Answer:
26.73 minutes have gone by
Step-by-step explanation:
Use cross multiplicationx 27
---- = ----- since we are trying to find how many minutes out of 99 passed,
99 100 place x for the missing digit
solvex times 100 = 99 times 27
simplifyx100 = 2673 x times 100 is just x100 since we don't know what x is, and 99
times 27 is 2673
figure for xx100 = 2673 to find x, it needs to be alone (x is very introverted :'> ) we can
---- ------- remove 100 by doing the opposite of what 100 is doing to the
100 100 x. Since it is 100 TIMES x, we will remove it by dividing 100 by
100 (which crosses it out) and then 2673 divided by 100. 2673
x = 26.73 divided by 100 gives us 26.73, so x equals 26.73.
