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!! :)

Step-by-step explanation:
Which fraction can be replaced with 1 2 when estimating with fractions? A. 10 12 B. 7 16 C. 2 9 D. 1 8
Answer:
B. 7/16
Step-by-step explanation:
The answer to this question is the option whose value is closest to 1/2.
We know that the fraction 1/2 is 0.5, now we have to get that fraction out of all these fractions that is closest to the value 0.5
10/12 = 0.833
7/16 = 0.43
2/9 = 0.222
1/8 = 0.125
The value closest to 0.5 is obviously 0.43 from the above. Therefore we can conclude that the fraction 7/16 is closets to 1/2 given these other fractions.
Thank you!

Answer:
15.) -21f - 16
16.) 5s + 2t
Step-by-step explanation:
15.)
-12f - 16 - 9f (Distribute 4 through the parentheses)
-21f - 16 (Collect like-terms)
16.)
4s + 2t + s + s - s (Since two opposites add up to zero, remove them from the expression)
4s + 2t + s (Collect like terms)
What is the area of this?
[tex]area = lw \\ area = (7.5)(6) \\ area = 45 {feet}^{2} [/tex]
[tex]area = \frac{1}{2} bh \\ area = \frac{1}{2} (6)(4) \\ area = \frac{1}{2} (24) \\ area = 12 {feet}^{2} [/tex]
total area = 45 + 12
total area = 57 feet²

Find the area of an equilateral triangle with side length 9.2 cm. Round your answer to 1 DP.
Answer:
Area=36.66 cm^2
Step-by-step explanation:
First, you need the height.
Use the Pythagorean theorem:
hypotenuse^2=height^2+(1/2 base)^2
It's one-half base because it's an equilateral triangle.
1/2 base =4.6
(9.2)^2-4.6^2=height^2
84.64-21.16=height^2
height^2=63.48
height=7.97
Area=(1/2)(base)(height)
Area=(1/2)(9.2)(7.97)=36.66 cm^2
Jeremy is 12 4 5 years old. Carl is 1 1 6 years younger than Jeremy and Jane is 1 1 3 years younger than Carl. How old is Jane?
Answer: Jane is 10 9/30 years old
Step-by-step explanation:
Given that Jeremy is 12 4 /5 years old
Carl is 1 1/6 years younger than Jeremy which is why we would subtract giving us
=12 4/5 - 1 1/6
= 11 (24- 5)/30
= 11 19/30 years
and Jane is 1 1 3 years younger than Carl which is why we would subtract giving us
=11 19/30 - 1 1/3
= 10 ( 19 - 10)/ 30
=10 9/30 years

80p2 - 180r2
Answer:
80p2 - 180r2
20(4p²-9r²)
20(2p+3r)(2p-3r)
Answer:
20(2p - 3r)(2p + 3r)
Step-by-step explanation:
Given
80p² - 180r² ← factor out 20 from each term
= 20(4p² - 9r²) ← difference of squares which factors in general as
a² - b² = (a - b)(a + b)
4p² - 9r²
= (2p)² - (3r)² ← with a = 2p and b = 3r
= (2p - 3r)(2p + 3r)
Thus
80p² - 180r² = 20(2p - 3r)(2p + 3r) ← in factored form
Write an equation of the line that passes through (−2,1) and is parallel to the line y=3x−4.
Equation: y=
Answer:
y = 3x+7
Step-by-step explanation:
the slope of parallel lines are the same so the slope is 3
y-y1 = 3(x - x1)
y- 1 = 3(x- -2)
y-1 = 3x +6
y = 3x +7

Select the three number bonds that represent factor pairs of the number 56. CLEAR CHECK Number bond: 1 times 56 = 56. Number bond: 4 times 14 = 56. Number bond: 5 times 6 = 56. Number bond: 7 times 8 = 56.
Answer:
The answer is -
Number bond: 1 times 56 = 56.
Number bond: 4 times 14 = 56.
Number bond: 7 times 8 = 56.
Step-by-step explanation:
We can define a factor pair as a set of two factors, which, when multiplied together, give a particular product.
For example -
5 and 6 are factors of 30 because 5×6 = 30
Now,
Given -
Number bond: 1 times 56 = 56. ...................(1)
Number bond: 4 times 14 = 56. ...................(2)
Number bond: 5 times 6 = 56. ...................(3)
Number bond: 7 times 8 = 56. ...................(4)
In equation (1)
1 times 56 = 1×56 = 56
⇒1 and 56 are the factor pairs of 56
Satisfies
In equation (2)
4 times 14 = 4×14 = 56
⇒4 and 14 are factor pairs of 56
Satisfies
In equation (3)
5 times 6 = 5×6 = 30 ≠ 56
⇒5 and 6 are not factor pairs of 56
Not Satisfies
In equation (4)
7 times 8 = 7×8 = 56
⇒7 and 8 are factor pairs of 56
Satisfies
∴ we get
The answer is -
Number bond: 1 times 56 = 56.
Number bond: 4 times 14 = 56.
Number bond: 7 times 8 = 56.
- The local museum requires 2 adult
chaperones for every 15 students. How
many adults would be needed with
90 students?
Answer:
For 90 students, 12 adult chaperones are required.
Step-by-step explanation:
90 (students) divided by 15 gives us a proportion to multiple the amount of adults by.
90/15 = 6
Since there are 6 times as many students as the question provided, we will multiply the amount of adults in the question by 6.
2 x 6 = 12

Subtract (-3f - 4g + 9) - (2 - 6f + 5g).
Answer:
Step-by-step explanation:
Remove the brackets. Watch out for that minus sign. It affects all three terms in the right bracket.
(-3f - 4g + 9) - (2 - 6f + 5g)
-3f - 4g + 9 - 2 + 6f - 5g
+3f - 9g + 7 is your answer.
Answer:
3f−9g+7
Step-by-step explanation:
(−3f−4g+9)−(2−6f+5g)
To find the opposite of 2−6f+5g, find the opposite of each term.
−3f−4g+9−2−(−6f)−5g
The opposite of −6f is 6f.
−3f−4g+9−2+6f−5g
Subtract 2 from 9 to get 7.
−3f−4g+7+6f−5g
Combine −3f and 6f to get 3f.
3f−4g+7−5g
Combine −4g and −5g to get −9g.
3f−9g+7
