5 or more? raise the score, 4 and below let it rest
The number in the tenths place, in this case, is 5 and the number next to it is 4, and since 4 is less than 5, you do not round 5 up to 6, you simply leave it alone!
Sumaya is using two different strings of Christmas lights to decorate her house.one string flashes every 10 seconds.the other one string flashes every 15 seconds.when Sumaya turns on the lights they flashes at the same time.work out how long it will be before they flash again at the same time.use the LCM to help you work out your answer
Answer: 30 seconds
Step-by-step explanation:
From the question, we are informed that one string flashes every 10 seconds while the other one string flashes every 15 seconds.
The number of minutes that it'll take before they both flash again at the same time will be gotten by calculating the LCM of 10 and 15. This will be:
10 = 10, 20, 30, 40, 50 ...
15 = 15, 30, 45, 60, 75 ....
We can see that the lowest common multiple of 10 and 15 is 30. Therefore, the answer is 30.
They'll both flash again at same time in 30 seconds.

Tanya thinks that to work out the median, she simply needs to find
the middle number. So she says that “37" is the median for this list of numbers.
Tanya's answer is not correct.
a) Describe what is wrong with her method.
b) Work out the median of the numbers in the list.
Answer:
a). To find the median from a set of numbers, you need to arrange them from ascending order (smallest to biggest), and then you need to find the number in the middle
b). 32
Step-by-step explanation:
b). Smallest to biggest
29, 30, 31, 32, 33, 34, 37
From the set of numbers given, we can clearly see that 32 is in the middle.

Answer:
66m*2
Step-by-step explanation:
2(20m + 13m)
= 66m*2
Answer:
66 m
Step-by-step explanation:
Since you are adding all the sides, you multiply 20x2 because there are two sides. Then you multiply 13x2 because 6 plus the missing number in the bottom right corner is equal to 7. The answer that you get from the multiplications, you add them and you have your perimeter.

A recipe calls for 1/4
cup of milk for every 1 1/2
cups of flour. How many cups of flour will you need for 1/2
cup of milk?
Answer:
3 cups flour
Step-by-step explanation:
set up a proportion and cross-multiply:
1/4 = 1/2
3/2 f
1/4f = 3/4
4f = 12
f = 3
Answer:
3 cups
Step-by-step explanation
basically if 1/4 cup of milk is for 1 1/2 cups of flour ------ 1/2 cup is twice the amount that a quarter cup is because a 1/4 cup + a 1/4 cup = 1/2 cup so you double the amount of flour too and 1 1/2 + 1 1/2 is 3 cups of flour.
1/4 + 1/4 = 1/2 (milk)
1 1/2 + 1/12 = 3 (flour)

Step-by-step explanation:
x+y=54.......equation 1
x=y-22........ equation 2
substitute
y-22+y=54
2y-22=54
2y=54+22
2y=76
y=76/2
y=38''
x=y-22
x=38-22

Cincinnati is about 225 miles from Cleveland. What is the distance between these cities on the map?
10 millimeters = 25 miles
Answer:90
Step-by-step explanation:
The distance between these cities on the map is 90 mm.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Cincinnati is about 225 miles from Cleveland and on scale 10 millimetres is equal to 25 miles.
The distance on the map will be calculated as,
25 miles = 10 mm
1 mile = 10 / 25 mm
225 miles = ( 225 x 10 ) / 25
225 miles = 90 mm
Therefore, the distance between these cities on the map is 90 mm.

Answer:
y - 7 = - [tex]\frac{5}{2}[/tex] (x + 2)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - [tex]\frac{5}{2}[/tex] and (a, b ) = (- 2, 7 ) , then
y - 7 = - [tex]\frac{5}{2}[/tex] (x - (- 2) ) , that is
y - 7 = - [tex]\frac{5}{2}[/tex] (x + 2)

A school hall costs £200 to hire.
Parents get a 10% discount.
30 parents share the cost equally.
How much does each parent pay
Answer:
£6
Step-by-step explanation:
The computation of the each parent pay is shown below;
But before that the cost of hall after considering the discount is
= £200 - 10% of £200
= £200 - £20
= £180
Now there are 30 parents
So each parent pay is
= £180 ÷ 30 parents
= £6
