In a school, 4 out of every 7 students are girls. if there are 84 students at the school, how many are boys. AND SHOW WORKING
Answer:36
Step-by-step explanation:
[tex]\frac{4}{7} =\frac{48\\}{84}[/tex]
for every 7 students there are 4 girls, so for every 84 there must be 48
7*12=84
4*12=48
so, in all 84 students there are 48 girls
so amount of boys=84-48=36
there are 36 boys
find the surface area of the cube below.
Answer:
150
Step-by-step explanation:
surface area =6a^2
= 6(5^2)
= 6×25
=150
Answer:
150 cm²
Step-by-step explanation:
So, firstly we must understand what does total surface area means (T.S.A)
We intuitively know that, it means,
Area of 6 EQUAL faces.
So,
Edge of the cube = 5 cm
Area of 1 face= 5 × 5= 25 cm²
Area of 6 faces= 25 × 6= 150 cm².
So, that means,
T.S.A= 150 Cm²
The radius of a circle is 12.8m. Find the circumference to the nearest tenth
Answer:
80.4
Step-by-step explanation:
The radius is 12.8m so to find circumference we have to multiply it by 2, 12.8x2 equals 25.6. Since we find our diameter we multiply 25.6 by pie or 3.14 and we 80.384 and round to the tenths place. Which is 80.4

Hey there!
The answer is "[tex]12 * 16 = 20^2[/tex], therefore the triangle is a [tex]right[/tex] [tex]triangle[/tex]"
This is known as the Pythagorean Theorem, meaning that [tex]a^2+b^2=c^2[/tex], with [tex]a[/tex] and [tex]b[/tex] being the length of the shorter of the three sides, and [tex]c[/tex] being the length of the hypotenuse, or the length of the longer of the three sides.

Factorise x^2+11x+18
Answer:
(x + 9)(x + 2 )
Step-by-step explanation:
Sum =11
Product = 18
Factors = 9 , 2
When you multiply (9*2 = 18) and when you add (9 +2 = 11).
x² + 11x + 18 = x² + 9x + 2x + (9*2)
=x(x + 9) + 2(x + 9)
= (x + 9)(x + 2 )
Answer:
(x+9) (x+2)
Step-by-step explanation:
x^2+11x+18
x^2+9x+2x+18
x(x+9)+2(x+9)
(x+9) (x+2)

Hank's car travels 600 feet in 20 seconds. Andy's motorcycle travels 300 feet in 12 seconds. Which is faster, the car or the motorcycle? Explain your reasoning.
Answer:
the car travels faster
Step-by-step explanation:
Since the motorcycle has traveled 300 feet, and the car has traveled 600 feet, we will divide 600 by 2
600 divided by 2 = 300
Hank would have traveled 300 feet in 10 seconds
Andy traveled 300 feet at 12 seconds
Therefore Hanks car travels faster
Answer:
The car travels faster
Step-by-step explanation:
600 ft per 20 secs
How many feet in one sec?
600/20 = 30
Hank's car = 30 feet per second
300 feet in 12 sec
How many feet in one sec?
300/12 = 25
Andy's motorcycle = 25 feet per second

3. 350%
4. 125%
5. 30%
6. 45%
7. 59%
8. 380%
Step-by-step explanation:
to find the precentage of a fraction u have to try and make the bottom number 100, 1000, 10000 etc
to do that like the first 1 u do 2 x ? = 100 the answer is 50
Rule what u do to the bottom u have to do to the top
now that u multiply 50 down to make 100 u have to do as the rule say what u need to do is also multiply 1 to 50 to get the answer
as u might know that 100 mean % so u pet the top number and then %
Which of the following is the maximum value of the function y = -x2 + 2x + 1?
We first complete the square.
y=-x^2+2x+1
y=-x^2+2x-1+1+1
y=-(x-1)^2+2
The maximum point is (1,2) since -1 in ( ) meant 1 unit to the right and +2 meant 2 units up.
The maximum point is (1,2) but the maximum value means the y value which is simply just 2.

Figure D'EFG' is a dilation with center (0,0) of figure DEFG. What is the scale factor? Enter your answer in the box.
ILL GIVE BRAINLIST BUT PPLEASE HELP
Step-by-step explanation:
To work out the scale factor, divide one of the sides from the larger shape from the smaller shape so:
15/6 = 2.5
So your scale factor would be 2.5
And to check this, multiply 2.5 by 6 and u should get 15, so you know it is correct! :)

How do you find the height of a parallelogram without the area of it?
Answer:
See: https://brainly.in/question/12682555
Step-by-step explanation:
The link provided will take you to a differently worded explanation from another user.
You may see the "slant" referred to as a "hypoteneuse", as the shape created by the line of height(or altitude) is a right triangle. Given the base of the triangle and the "slant" or "hypoteneuse", format the equation (a²+b²=c²)-where a represents the height(altitude), b represents the base, and c represents the slant(hypoteneuse)- to fit your needs:
c²-b²=a². From this point, find the square root(√) of a. If it cannot be simplified further, then (√a) is your solution.
