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

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.

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 =

What is the surface area of cuboid?Let the three dimensions(height, length, width) be x, y,z units respectively.
The surface area of the cuboid is given by
[tex]S = 2(a\times b + b\times c + c\times a)[/tex]
A box is usually in shape of a cuboid.
For this case, its dimensions are 10 inches, 10 inches, and 6 inches.
The amount of wrapper we need is approx same as the area of its surface (assuming we're going to measure the paper needed in terms of its area).
Thus, we get:
Amount of the paper we need to wrap the considered box = surface area of that box = surface area of cuboid of dimension 10 inch by 10 inch by 6 inches = S (say), then:
[tex]S = 2(10\times 10+ 10\times 6 + 6\times 10)\\S = 440[/tex](in sq. inches)
Thus, the amount of paper needed to wrap the considered box which has dimension of 10 by 10 by 6 inches is 440 sq. inches

Maria bought g gallons of gasoline for $4.75 per gallon and c cans of oil for $5.15 per can.
a. What expression can be used to determine the total amount Maria spent on gasoline and oil?
b. If she bought 7.8 gallons of gasoline and 9 cans of oil, how much did she spend in all?
Answer:
a) 4.75g + 5.15c
b) $83.40
Step-by-step explanation:
Gasoline = $4.75 per gallon
Oil = $5.15 per can
Let g = number of gallons
Let c = number of cans
a) Total spend = 4.75g + 5.15c
b) Given:
g = 7.8c = 9⇒ total spend = 4.75(7.8) + 5.15(9)
= 37.05 + 46.35
= $83.40
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.

second page is 4.5
third page is is 25.5
fourth page is 62.5
Answer:
25% of £90 = £22.50
25% of £18 = £4.50
85% of 30 = £25.50
15% of £24 = £3.60
Step-by-step explanation:
For some of the answers, I can see you've got the digits correct, but it is important that you add the 0 for the .5 since it is in money terms. e.g. not 4.5, but £4.50.
With percentages, it is useful to break them down into easier percentages to solve. For example, instead of thinking of 15%, think of 10% + 5%. Finding 10% of a number is easy - divide it by 10. So 10% of 24 would be 2.4. And 5% of 24 is just 10% divided by 2, because 10 divided by 2 is 5. So 5% of 24 is 2.4 divided by 2, so 5% of 24 = 1.2
10% + 5% = 15% = 2.4 + 1.2 = 3.6
And because it is in money terms, we need to add the 0, to make it:
£3.60.
