There are a total of 96 children in Years 4, 5 and 6
37 of these children cannot swim.
11 children in Year 4 cannot swim.
21 children in Year 5 can swim.
There are 30 children in Year 6
18 of these 30 children can swim.
(i) Work out the number of children in Year 4 who can swim.
Answer: 20 children
Step-by-step explanation:
Given
Year 4: 11 cannot swim
Year 5: 21 can swim
Year 6: 18 of 30 can swim
Total 96 children
Total 37 cannot swim
First Step: find the number of people from year 5 who cannot swim
There are 30-18=12 people who cannot swim in year 6There are 11 who cannot swim in year 4Thus, we use the total number [37]-[year 4+year 6]=37-23=14 people who cannot swim in the year 5Second Step: find the number of children in year 5
There are 21 children who can swimThere are 14 children who cannot swim21+14=35 childrenThird Step: find the number of children in year 4 who can swim
There are 30 children in year 6There are 35 children in year 5There are 11 children in year 4 who cannot swimThere are in total 96 children96-30-35-11=20 children in year 4 who can swimHope this helps!! :)

Find the missing value to the nearest hundredth cos=4/38
Answer:
83.96 (approximately)
Step-by-step explanation:
I am not completely sure what the problem is asking, just like the last one, but I believe that you are just supposed to take the inverse of cosine. So, in your calculator, make sure it is in degrees mode, then usually you have to click the 2nd key and then cosine. You use the inverse of cosine when two sides are given, but you are not given the angle.
It should look like:
[tex]cos^{-1}(\frac{4}{38})[/tex], which is approximately 83.96.
Hopefully this is right, if not, please let me know. Good luck.

Find the area of the trapezoid by decomposing it into other shapes
Answer:
60 cm ( squared )
Step-by-step explanation:
you can find the area of the trapezoid ( by decomposing it into other shapes ) by separating two triangles, and using the formula to find the area of triangles, which is A= 1/2 ( b x h ) and add the answer to those together ( 16 cm squared and 4 cm squared ), and after that, you can find the area to the rectangle by multiplying the l x w, which is 10 x 4 ( after separating the triangles.). That equals 40, and when you add them all together ( 16 + 4 + 40 ) it equals 60 cm (squared).

A restaurant makes pizzas with 6-inch diameters ad 12-inch diameters. Which of the following statement is true?
The area of the 12-inch pizza is twice the area of the 6- inch pizza
The area of the 12-inch pizza is three times the area of the 6-inch pizza
the area of the 6-inch pizza is 1/4 the area of the 12-inch pizza
the area of the 6-inch pizza is 1/6 the area of the 12-inch pizza
Answer:
The correct option is c: the area of the 6-inch pizza is 1/4 the area of the 12-inch pizza.
Step-by-step explanation:
The area (A) of each pizza is given by:
[tex] A = \pi r^{2} [/tex]
Where:
r: is the radius
For the 12-inch pizza we have:
[tex] A_{12} = \pi (\frac{12 inch}{2})^{2} = 113.1 inch [/tex]
And for the 6-inch pizza we have:
[tex] A_{6} = \pi (\frac{6 inch}{2})^{2} = 28.3 inch [/tex]
The ratio between A₆ and A₁₂ is:
[tex] \frac{A_{6}}{A_{12}} = \frac{28.3 inch}{113.1 inch} = 0.25 = \frac{1}{4} [/tex]
Hence:
[tex] A_{6} = \frac{A_{12}}{4} [/tex]
Therefore, the correct option is c: the area of the 6-inch pizza is 1/4 the area of the 12-inch pizza.
I hope it helps you!
The area of the 6-inch pizza is 1/4 the area of the 12-inch pizza
Given that;Diameter of pizza A = 12 inch
Diameter of pizza B = 6 inch
Computation:Ration of Area of Pizza A to B = [πr1²] / [πr2²]
Ration of Area of Pizza A to B = [(12/2)²] / [(6/2)²]
Ration of Area of Pizza A to B = [(6)²] / [(3)²]
Ration of Area of Pizza A to B = 36 / 9
Ration of Area of Pizza A to B = 4:1
So,
Option "C" is the correct answer of the following question.

Answer:
in about 27 days
Step-by-step explanation:
i assumed 30 days per month when i set up this equation:
w = words learned daily
100 + 4w = 180 + 30/30w
100 + 4w = 180 + w
3w = 80
w = 26 2/3
Answer:
3.86 weeks/three weeks
Step-by-step explanation:
x time it takes for thier vocab to be the same in days
so the boy lerns 360 words of spanish in a year
or 360/365 words of spanish per day which is 72/73 words per day
so,
100+4x=180+72x/73
80=288x/73-72x/73
80=216x/73
80*73=5,840
5,840=216x
27.037 days=x
so now we have to divide by seven to get weeks so that is 3.86 weeks.
so some time in week three

Standard to Slope Intercept Form
Put the following equation of a line into slope-intercept form, simplifying all fractions.
2x+8y=24
Answer:
y = - [tex]\frac{1}{4}[/tex] x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
2x + 8y = 24 ( subtract 2x from both sides )
8y = - 2x + 24 ( divide all terms by 8 )
y = - [tex]\frac{1}{4}[/tex] x + 3 ← in slope- intercept form

Jessica estimated that her family used 30% more water this month compared to last month . they used 12000 gallons of water last month , how much water did they use this month
Answer:
15,600 Gallons
Step-by-step explanation:
The 30% of 12000 is 3600 thus, Jessica's family used 15600 gallons of water.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Last used of water = 12000
30% of 12000 = (30/100)12000 = 3600
Water used in the current year = 12000 + 3600 = 15600 gallons.
Hence "The 30% of 12000 is 3600 thus, Jessica's family used 15600 gallons of water".
