Answer:
170 in²
Step-by-step explanation:
Given that :
Side, a = 14 in
Angle formed =? 60°
Take height, = l
The ratio of height to side = Sine of the angle formed
l /s = Sine 60°
Sin 60 = sqrt(3)/2
l/s = sqrt(3)/2
l = sqrt(3)/2 * s
s = 14
l = 14 * sqrt(3)/2
l = 7sqrt(3)
Area of rhombus :
l * s
7sqrt(3) * 14
= 169.74097
= 169.74 in²
= 170 (nearest square inch)
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.

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)

There are only 5 blue cards, 2 green cards and 4 red cards in a pack.
Isabella is going to take at random one card from the pack.
(a) Write down the probability that Isabella will take a blue card.
Answer:
5/11 or 45 percent, since there are 5 blue cards
The probability that Isabella will take a blue card is 5/11.
What is probability?Probability is the chance that something will happen, or how likely it is that an event will occur.
Formula for probabilityP(E) = total number of favorable outcomes/ total number of outcomes
Where,
P(E) is the probability of any event.
According to the given question
Five blue cards, two green cards and four red cards.
⇒ total number of outcomes = 5+ 2 + 4 = 11
For finding the probability of blue card
Total number of blue cards is 5.
⇒ total number of favorable outcomes = 5
Therefore,
The probability of getting blue card
= number of favorable outcomes/ total number of outcome
= [tex]\frac{5}{11}[/tex]
Hence, the probability that Isabella will take a blue card is 5/11.

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.

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

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)
