What is the width of the lid?
Answers
Answer:
The width of the lid is 15 cm
Step-by-step explanation:
The Perimeter of a Rectangle
Given a rectangle of width W and height H, the perimeter is calculated as:
P = 2(W + L)
Jon used 56 cm of ribbon to go around the edge of a rectangular lid. This means the perimeter is:
2(W + L) = 56
Dividing by 2:
W + L = 28
Since the lid was L=13 cm long, the width is:
W = 28 - 13 = 15
The width of the lid is 15 cm

write an equation of the line in a slope intercept form has a slope of -1/2 and passes through the point (2, 3)
Answers
Answer:
y = -¹/₂ x + 4Step-by-step explanation:
The point-slope form of the equation is y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope:
m = -¹/₂
(2, 3) ⇒ x₀ = 2, y₀ = 3
The point-slope form of the equation:
y - 3 = -¹/₂ (x - 2)
So:
y - 3 = -¹/₂ x + 1 {add 3 to both sides}
y = -¹/₂ x + 4 ← the slope-intercept form of the equation

Answer:
348 of them are not postgraduates
Step-by-step explanation:
Answer:
348
Step-by-step explanation:
Out of 725 employees, 52% are postgraduates.
First find the percentage who are not postgraduates, or the "remaining."
100% - 52% = 48%
48% of 725 employees = how many employees?
48/100 × x/725
Cross multiply
48 × 725 = 100 × x
34800 = 100x
Divide both sides by 100
34800 ÷ 100 = 100x ÷ 100
348 = 1x
348 employees are not postgraduates

A livestock pen is built in the shape of a rectangle that is four times as long as is wide. The total perimeter is 60 ft. Write an equation that models the perimeter in terms of width and/or length, find the length and width.
Answers
Answer:
Perimeter = 60ft = 2(4x + x)
breadth = 6ft
length = 24ft
Step-by-step explanation:
Perimeter = 2 (L + B)
L =length
B = Breadth
x= breadth
4x = length
Perimeter = 60ft = 2(4x + x)
Dividing both sides by 2 :
30ft= 4x + x
30ft = 5x
divide both sides by 5
6ft= x
breadth = 6ft
length = 4x= 4 x 6 = 24ft

Answer:
The coordinates of point B are: (29,-15)
Option D is correct option.
Step-by-step explanation:
Endpoint of diameter of a circle = A(5,7)
Centre of circle = P(17,-4)
We need to find coordinates of other endpoint of diameter of a circle i.e. B
The formula used is: [tex]Midpoint=(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})[/tex]
We are given coordinates of centre (midpoint) P(17,-4)
and A (5,7) x₁=5, y₁=7
We need to find Point B i.e. (x₂,y₂)
Putting values and finding point B
[tex]Midpoint=(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})\\(17,-4)=(\frac{5+x_2}{2}, \frac{7+y_2}{2})\\We\:can\:write:\\17=\frac{5+x_2}{2}\:and\: -4=\frac{7+y_2}{2}\\17\times 2=5+x_2\:and\: -4\times 2=7+y_2\\34=5+x_2\:and\: -8=7+y_2\\34-5=x_2\:and\: -8-7=y_2\\x_2=29\:and\: y_2=-15[/tex]
so, we get: x₂ = 29 ,y₂ = -15
The coordinates of point B are: (29,-15)
Option D is correct option.

Francis owns a camping supply store and just put in an order for flashlights and sleeping
bags. The number of flashlights ordered was five times the number of sleeping bags ordered.
The flashlights cost $12 each and the sleeping bags cost $45 each. If the total cost for the
flashlights and sleeping bags was $1785, how many sleeping bags did Francis order?
Answers
Answer:
The number of sleeping bags bought is 17.
Step-by-step explanation:
If we let "x" be the number of the sleeping bags that were bought, we can make the following equation....
(5x)(12) + (x)(45) = 1785
By solving the equation we get....
(5x)(12) + (x)(45) = 1785
60x + 45x = 1785
105x = 1785
x = 1785 / 105
x = 17
There for the number of sleeping bags bough is 17.

Step-by-step explanation:
first look at the scale factor going from 4 to 10, to get from 4 to 10 you would need to multiply 4 by 2.5. Since this problem doesnt give us the smaller scale factor first we need to divide 25 by 2.5 which equals 10.
A company makes Poppy Lapel Pins.
Each of them costs £1.10 to make.
In October it made 1000 lapel pins.
35% of them are given to charities.
The rest are sold in two formats: 60% of them at £3.00 each
40% of them at £5.00 for 2
Assuming that all the lapel pins will be sold by the end of November,
work out the percentage profit the company should make.
Give your answer to 1 decimal place.
Answers
Answer:
1000 less 35% == 650
so 250 given to charity
total cost making the pins was 1000x 1.10 = 1100
so you need to find 60 percent of 650 =390
and 40 percent of 650 = 260
so then you need to find the cost 390 x 3 pounds each so × this and gives you 1170 cost sold for intotal
Then you have 260 ÷2 = 130 x 5 = 650
so you have 650+1170 = 1820 - 1100 cost to make =720 pounds

Step-by-step explanation:
You can round it by looking at the hundredths place.
Look to the thousandths place, if its 5 or more, you round up, if its 4 or less you round down.
Answer:
the way that you do this is
Step-by-step explanation:
so the number goes from 0 as in the whole number and then the decimal indicates that the whole number getting separated by a whole bunch of other numbers which go by smaller factors they go from ten hundred thousand and so forth so for this equation you have 0.234 the hundreds is the three the reason why is because the two is the tenths and the four is the thousands the reason why it's the thousands is because there's four numbers in the entire number. so that number (0.234) would be 0.23 rounded to the nearest hundreth because the 4 is less than 5 which makes the number go lower. If it was 0.238 then the answer would now be 0.24 because it's higher then 5. please give me brainliest.
