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

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

Given that we know,

£1 = 1.12 Euro's.

To Simply convert it to Euro's you would multiply, 1.12 x 9 in order to find out what £9 is worth in Euro's.

Thus giving you,

10.08 Euro's

Answer:

1)50% , 2) 25% 3) 350%

Step-by-step explanation:

pls follow me not because I am genius but because I am a swager SWAG

Answer:

1. 50%

2. 25%

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 %

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)

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

Answer:

0.15

Step-by-step explanation:

6 divided by 24 equals 0.25

12 divided by 30 equals 0.4

0.4 minus 0.25 is 0.15

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.

Answer:

x=139

Step-by-step explanation:

x and 139 are alternate exterior angles. Since a transversal passes through lines m and n, They are congruent using the alt. interior angle theorem.

so x=139

Hi!! I'd love to help!!

The slope of your points is 2.

When we use the slope intercept formula (y=mx+b), we get y=2x-2.

So the answer to your question is C

Hope this helps!! Let me know if you need any more help or have questions/concerns.

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.

Done!

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.

X > 3/7

We know that the student sleeps in at least 3 days, but we don't know what the exact number is, we use an inequality where X is greater than or equal to 3 out of the 7 days.

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! :)

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

Answer:

Well Circumference = πr^2, but I don't know what you're asking for?
